• Should I work with multiple recruiters for a job search or just pick one?

  - by BuckeyeSoftwareGuy

  So I posted my resume on dice and monster last night and today I've received 5 voicemails and about 6 emails from different recruiters wanting to talk to me. What's the best way to handle this situation. I want to reply to them all of course as I'm very interested in making an imminent job change. Is there some sort of rule of thumb here? It seems to me they would want to work with me exclusively if they could. I don't want to limit my options though..

• Career Day in kindergarten: how to demonstrate programming in 20 minutes?

  - by Péter Török

  I was invited to the kindergarten group of my elder daughter to talk, and aswer the kids' questions, about my profession. There are 26 kids of age 4-6 in the group (plus 3 teachers who are fairly scared of anything related to programming and IT themselves, but bold enough to learn new tricks). I would have about 20-30 minutes, without projector or anything. (They have an old computer though, which by its look may be a 486, and I am not even sure if it's functioning.) My research turned up excellent earlier threads, with lots of good tips: How would you explain your job to a 5-year old? Career Day: how do I make “computer programmer” sound cool to 8 year olds? What things can I teach a group of children about programming in one day? My situation is different from each of the above though. So any advice on how to teach the kids (and their teachers) in a fun way about programming is appreciated.

• What video conferencing software is suitable for communicating with clients?

  - by Nick Retallack

  You're working freelance with several small remote clients and you want to have a meeting via webcam. What do you use? Please consider price, video quality, and minimum hassle for the clients. I'd prefer my clients don't have to pay anything or install anything for it to work. I'm already serving VNC in a Java applet, so something like that would be nice. Skype is awesome, and oovoo looks great, but I'd like to have more than one client on the line at once without them having to pay a subscription too. Something like Ustream.com or Justin.tv would be nice, but it would be better if all parties could talk. Related Questions: Can someone suggest free video conferencing tools

• How to scale MySQL with multiple machines?

  - by erotsppa

  I have a web app running LAMP. We recently have an increase in load and is now looking at solutions to scale. Scaling apache is pretty easy we are just going to have multiple multiple machines hosting it and round robin the incoming traffic. However, each instance of apache will talk with MySQL and eventually MySQL will be overloaded. How to scale MySQL across multiple machines in this setup? I have already looked at this but specifically we need the updates from the DB available immediately so I don't think replication is a good strategy here? Also hopefully this can be done with minimal code change. PS. We have around a 1:1 read-write ratio.

• Using pyodbc to insert rows into a MS Access MDB, how do I escape the paramaters?

  - by MDBGuy

  Hi, I'm using pyodbc to talk to a legacy Access 2000 .mdb file. I've got a cursor, and am trying to execute this: c.execute("INSERT INTO [Accounts] ([Name], [TypeID], [StatusID], [AccountCat], [id]) VALUES (?, ?, ?, ?, ?)", [u'test', 20, 10, 4, 2]) However, doing so results in pyodbc.Error: ('HYC00', '[HYC00] [Microsoft][ODBC Microsoft Access Driver]Optional feature not implemented (106) (SQLBindParameter)') I understand I can simply change the question marks to the literal values, but in my experience proper escaping of strings across databases is... not pretty. PHP and mysql team up to bring mysql_real_escape_string and friends, but I can't seem to find pyodbc's function for escaping values. If you could let me know what the recommended way of inserting this data (from python) is, that'd be very helpful. Alternatively, if you have a python function to escape the odbc strings, that would also be great. Thanks for the help.

• Basecamp API Rails

  - by dannymcc

  Hi Everyone, I was wondering if someone could do me massive favour.. I really don't understand how to make use of API's - so I was wondering if, using Basecamp as an example, someone could talk me though the basics. So far I have an application with a dashboard controller/view, I have put basecamp.rb into my /lib directory, added the following to my application_controller: def basecamp_connect Basecamp.establish_connection!('XXXXXX.basecamphq.com', 'USER', 'PASS', false) @basecamp = Basecamp.new end Obviously changing the required parts to my credentials. Next up I have added the following to my dashboard_controller: def index Basecamp::TodoList.find(:all) end Next I presume I have to somehow list the Todo's on the dashboard using some sort of loop. Am I doing the right thing, if so - how on earth do I display all the todo items and if not - what am I doing wrong/missing. It doesn't have to be todo's, anything from basecamp or any other popular API service would be a good start. It's just that I happen to have a basecamp account! Thanks, Danny

• Calling a running C# application from VBA

  - by Robert

  I have some VBA code that needs to talk to a running c# application. For what it's worth, the c# application runs as a service, and exposes an interface via .net remoting. I posted a question regarding a specific problem I'm having already (http://stackoverflow.com/questions/2556163/from-vb6-to-net-via-com-and-remoting-what-a-mess) but I think I may have my structure all wrong... So I'm taking a step back - what's the best way to go about doing this? One thing that's worth taking into account is that I want to call into the running application - not just call a precompiled DLL...

• Free internet radio station server software with remote broadcasting?

  - by Zachary Brown

  I am in the process of creating an internet radio station, but the two djs I have for it are not able to be in one place. I need for them to be able to login to a web based broadcasting session that still has full functionality. They need to be able to broadcast thier live shows with talk and music. The music will be stroed on the server. I have checked out the Broadwave media streaming server from NCH, but ti does not have the ability to login as a dj from a remote computer. I don't have any money for this, so I need it to be free. If this is not possible, I need it to be cheap!

• Using SWFObject, the flash moves 1 pixel to the right on Firefox

  - by jeffkee

  Please check this page: http://islandhideaway.weebly.com/ For whatever reason, the flash slideshow moves over 1 pixel when opened in Firefox on my Mac. All other browsers render it fine, but only on Firefox it leaves a 1 pixel white gap on the left! I am using the most recent version of SWFObject. This unfortunately is a garbage Weebly site and I cannot use jQuery in the system so I can't do a real gallery... so let's save the whole "don't use Flash for that" pep talk. It's a favour for a friend and I am already aware of better ways to do it. :)

• Sending message to windows service by web page

  - by Enriquev

  Hello, How could I do this with no access denied problem? I have a windows service: protected override void OnCustomCommand(int command) { if (command == 1) { foreach (Process traceProcess in Process.GetProcessesByName("notepad.exe")) { traceProcess.Kill(); } } } when I do this: ServiceController sc = new ServiceController("ProjectManager"); if (sc != null) sc.ExecuteCommand(1); From a windows forms it works, but not from a web page, I get access denied on sc.ExecuteCommand. What's the best way for a web page to talk to a service?

• Wrapper around bash, control STDIN and STDOUT

  - by blinry

  I would like to talk to a interactive bash process. Here is an example, so you know what I want to archieve: Program starts a new bash process. User types "ls" into my program. Program sends this command to the bash process. Program reads all available output of the bash (including the prompt) and displays it back to the user. GOTO 1 As you can guess, there is much room for nifty manipulations here and there... ;-) It would be wonderful if this also worked for subprocesses (started by the bash process) and curses-based programs. I would like to implement this functionality in Ruby, and already have experimented with IO.popen, but strange things happen. You are also welcome to do this in other languages.

• Is there a social networking protocol

  - by Marwan

  Social networking is great, but there is something fundamentally wrong with the way social networking is implemented today in most popular services. I'll put it in this example: Imagine that there is no SMTP, and consequently, it is globally assumed and accepted that you can only send email to addresses on the same domain. The result would be the emergence of a single email service, let's call it emailbook.com, which we all have to subscribe to, if we really want to communicate with the world. This is what's happening with social networking today. You HAVE to use the same service your fiends/colleagues are using to talk to them. I would like to be able to put up my own social site, invite my friends who trust me, share amongst us, but still be able to share with the world at large. What are the chances of this scenario happening in the future? What does it take?

• gcc-4.2 failed with exit code 1 iphone

  - by SKayser

  Hi, I've seen this error with different variations on discussion forums but being a non programmer I'm not sure how to progress this. Basically I have code which I found to help me with changing the background colors of cells on a grouped uitableview. The code introduced a line as such: CGContextAddArcToPoint(c, minx, miny, midx, miny, ROUND_SIZE); This gave an error indicated that it wasn't declared, so I added to my .h file the following under import uikit: #import <UIKit/UIKit.h> #define ROUND_SIZE 10 Now it shows that I have an error: Command/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.2 failed with exit code 1 iphone Some discussions talk about libraries but because I don't have a programming background I don't understand what to do. I also see that some people show a log output but I'm not sure where that comes from as I don't get any debug windows because I'm guessing it doesn't get that far. I simply click 'Build and Go' and I get this error in the Message window. Any thoughts?

• fastest (low latency) method for Inter Process Communication between Java and C/C++

  - by Bastien

  Hello, I have a Java app, connecting through TCP socket to a "server" developed in C/C++. both app & server are running on the same machine, a Solaris box (but we're considering migrating to Linux eventually). type of data exchanged is simple messages (login, login ACK, then client asks for something, server replies). each message is around 300 bytes long. Currently we're using Sockets, and all is OK, however I'm looking for a faster way to exchange data (lower latency), using IPC methods. I've been researching the net and came up with references to the following technologies: - shared memory - pipes - queues but I couldn't find proper analysis of their respective performances, neither how to implement them in both JAVA and C/C++ (so that they can talk to each other), except maybe pipes that I could imagine how to do. can anyone comment about performances & feasibility of each method in this context ? any pointer / link to useful implementation information ? thanks for your help

• Convert Double to String without precision loss in javascript

  - by holger

  I would like to convert a floating point variable to a string without losing any precision. I.e. I would like the string to have the same information as my floating point variable contains, since I use the output for further processing (even if it means that the string will be very long and readable). To put this more clearly, I would like to have functions for cyclic conversion var dA = 323423.23423423e4; var sA = toString(dA); var dnA = toDouble(sA); and I would like dnA and dA to be equal Thanks PS: Sources on the internet usually talk about how to round strings but I have not found information on exact representation. Also I am not interested in Arbitrary Precision calculations, I just need double precision floating point arithmetic.

• Download Drools RuleFlow files from Guvnor

  - by Shakil Siraj

  Hello all, I can upload RuleFlow (.rf) files to Guvnor (both 5.1 M1 and 5.0) and execute them with rules on the server. If I want to use Guvnor as a repository, is there any way I can download the RuleFlow files into my project on the fly? On the package level, Guvnor provides some "Information and Important URLs" which only talk about rules. I was wondering if there is any other URL which will give me the RuleFlow files? Is WebDav my only other option? Thanks in adavance.

• WCF, 4.0, Bidirectional...

  - by TomTom

  ...what options are there now with .NET 4.0, in a way that does support NAT for the client side (i.e. client behind NAT). I would prefer to use something HTTP based, but that is a weak condition - I think mid term I will have some non http communication outside WCF anyway, so proxy traversal is something I could delay. Pre .NET 4.0 there was the issue that basically the server-client channel would be opened from the server, which made NAT something non-traversable. Polling is not acceptable - we talk time sensitive information here. So, what are my options now?

• Why does the ASP.Net Web Forms model "suck"?

  - by Daniel Magliola

  I've heard Jeff Atwood, Joel Spolsky, and many other legendary people talk about how the ASP.Net Web Forms model sucks. (So this question is kind of directed to them, hopefully Jeff is reading) Now, I highly respect their opinion, given their background and expertise, but truth be told, I absolutely LOVE ASP.Net. I think the model is brilliant, and it sucks if you have no idea what you're doing, but once you understand how to control ViewState, when to use handlers instead of pages, etc, it is generations ahead of all the other models. So every time I hear someone complain about how it sucks, I can't help ask the same question... Why? What is it that's so bad about it? I appreciate all opinions. I'm assuming there's probably a post at Jeff's blog talking about this too...

• Why GWT? Advantages and Trade-Offs of Using This RIA Framework

  - by prometheus

  I'm new to stackoverflow and have been reading through a bunch of the "highest voted" questions for GWT. Several of these questions talk about the pitfalls or problems with GWT. In the articles: Which Javascript framework (jQuery vs Dojo vs … )? and Biggest GWT Pitfalls?, some posters seem to suggest that GWT is not lightweight enough or that there are better alternatives that may be used. Do most of you feel that there are problems with GWT that have not been fixed with GWT 2.0 -- which would make you inclined to suggest using a simpler framework for a new project? To some extent, shouldn't GWT be somewhat future-proof (since you don't have to worry about it changing drastically from release to release and since it is backed by Google)? I realize that the answer to this question depends greatly upon what you want to do or what you wish to make. I am looking at this from the perspective of starting a new web application that will eventually be used by millions of users.

• How do i redirect to a GET request from a POST request on GAE

  - by user259349

  Hello everyone, i am writing an FBML app on facebook hosted in GAE. Facebook will talk to your hosted app only vai POST (im sure this is the cause, but please do correct me if i'm wrong). So im faced with the issue that inside of my POST method, i need to redirect to facebook OAuth authroize URL. But i can only send a GET request. How can i do that? At the moment i'm doing class OauthHandler(webapp.RequestHandler): def post(self): # blablablab request.redirect(oauth_uri) Which is wrong since the oauth_uri is only responding to GET. Further more, OAuth will redirect back to my redirect handler through GET, but i cant! i can only do post. So i'm confused. ideas? Thanks in advance

• SQL searching table fields with LIKE

  - by Tom Gullen

  Given your data stored somewhere in a database: Hello my name is Tom I like dinosaurs to talk about SQL. SQL is amazing. I really like SQL. We want to implement a site search, allowing visitors to enter terms and return relating records. A user might search for: Dinosaurs And the SQL: WHERE articleBody LIKE '%Dinosaurs%' Copes fine with returning the correct set of records. How would we cope however, if a user mispells dinosaurs? IE: Dinosores (Poor sore dino). How can we search allowing for error in spelling? We can associate common misspellings we see in search with the correct spelling, and then search on the original terms + corrected term, but this is time consuming to maintain. Any way programatically?

• Add api key to every request in ActiveResource

  - by Jared

  I have 2 RESTful Rails apps I'm trying to make talk to each other. Both are written in Rails 3 (beta3 at the moment). The requests to the service will require the use an api key which is just a param that needs to be on every request. I can't seem to find any information on how to do this. You define the url the resource connects to via the site= method. There should be an equivalent query_params= method or similar. There is one good blog post I found related to this and it's from October 2008, so not exactly useful for Rails 3.

• Talking to an Authentication Server

  - by Kyle Terry

  I'm building my startup and I'm thinking ahead for shared use of services. So far I want to allow people who have a user account on one app to be able to use the same user account on another app. This means I will have to build an authentication server. I would like some opinions on how to allow an app to talk to the authentication server. Should I use curl? Should I use Python's http libs? All the code will be in Python. All it's going to do is ask the authentication server if the person is allowed to use that app and the auth server will return a JSON user object. All authorization (roles and resources) will be app independent, so this app will not have to handle that. Sorry if this seems a bit newbish; this is the first time I have separated authentication from the actual application.
