• Using a AWS EC2 Server to host a busy website and I need to set up a loadbalancing

  - by Philip Isaacs

  My company has one EC2 server running on AWS with a MYSQL-DB and Apache on the same instance. This one instance hosts a website built on PHP Zend Framework. The site runs like crap when it starts to get busy with a lot of traffic so I'm looking for some advice on how to set up something that can handle the load better. My first question is should I move the mysql DB on to a separate EC2 instance or perhaps use AWS's RDS service which looks like a nice option. I'm sort of new to some of this but I'm guessing I'll need at least two EC2 instances for serving the website from and some sort of load balancing mechanism to distribute traffic. But maybe not, I'm not sure. Also what are some best practices for how to replicate the data so that they stay in sync on both instances? Okay I know these are a lot of questions. But I don't know where to start so any advice will help.

• mysql_connect "bool $new_link = true" is very slow

  - by Mikk

  Hi, I'm using latest version of Xampp on 64bit Win7. The problem is that, when I use mysql_connect with "bool $new_link" set to true like so: mysql_connect('localhost', 'root', 'my_password', TRUE); script execution time increases dramatically (about 0,5 seconds per connection, and when I have 4 diffirent objects using different connections, it takes ~2 seconds). Is setting "bool $new_link" to true, generally a bad idea or could it just be some problem with my software configuration. Thank you.

• Does this introduce security vulnerabilities?

  - by mcmt

  I don't think I'm missing anything. Then again I'm kind of a newbie. def GET(self, filename): name = urllib.unquote(filename) full = path.abspath(path.join(STATIC_PATH, filename)) #Make sure request is not tricksy and tries to get out of #the directory, e.g. filename = "../.ssh/id_rsa". GET OUTTA HERE assert full[:len(STATIC_PATH)] == STATIC_PATH, "bad path" return open(full).read()

• What is the best programming language for web development and why?

  - by Logan Serman

  I've always used PHP, but recently I've been reading about why it's bad. I love Python, but I don't know how it works with the web. I've never even seen Ruby... what is worth learning? Should I stick to PHP?

• Programming Language Choices for High Integrity Systems

  - by Finbarr

  What programming languages are a good choice for High Integrity Systems? An example of a bad choice is Java as there is a considerable amount of code that is inaccessible to the programmer. I am looking for examples of strongly typed, block structured languages where the programmer is responsible for 100% of the code, and there is as little interference from things like a JVM as possible. Compilers will obviously be an issue. Language must have a complete and unambiguous definition.

• Why do so many programmers consider Visual Basic a poor language? [closed]

  - by Mike

  Why do programmers consider Visual Basic a bad language? Putting aside any gripes with Microsoft or with proprietary/non-free software in general, and looking the language itself. Syntax, style, etc. I have just started using it, and find the syntax rather terrible. But I'm wondering what are the most common specific problems.

• Permissions to run a SharePoint 2010 Application Pool?

  - by Michael Stum

  I'm currently in the process of setting up a SharePoint 2010 farm. In my Dev Environments, I have one account that is Local Admin, Farm Administrator and runs all Application Pools. For Production Environment, I would like to go with best Security Practices and run the Web Applications (At least 2: Main Portal and My Sites) with separate Domain Accounts. It's been some time that I worked with IIS, and I remember that there were issues with accessing files in c:\inetpub by non-Admin users. On the other hand, SharePoint "automagically" sets most permissions anyway. Does anyone have some experience with which permissions I need to give to the domain account at minimum in order to work?

• Eclipse vs Netbeans

  - by Zenzen

  Some time ago (~4-5months ago) I attented a lecture about JEE and at some point the lecturer started talking about webservices and how hard it is to create a good one because all the IDEs make them in a bit different way (or something like that) and that in general it's better to use Netbeans to create them as Eclipse has some issues, the thing is he didn't really say why Eclipse is bad. Now I'm wondering is what he said true and why, is it really better to use Netbeans for webservices and why?

• Malicious crawler blocker for ASP.NET

  - by Marek

  I have just stumbled upon Bad Behavior - a plugin for PHP that promises to detect spam and malicious crawlers by preventing them from accessing the site at all. Does something similar exist for ASP.NET/ASP.NET MVC? I am interested in blocking access to the site altogether, not in detecting spam after it was posted.

• 389 DS Achitecture for Multiple Sites

  - by Kyle Flavin

  I'm looking to deploy 389 Directory in my environment to replace an existing iPlanet installation. I would be using it primarily to store user account data for authentication purposes. I have two physically separate data centers that I would like to share the same directory tree. My initial thinking is to setup 389 DS as follows: -A Master/Consumer in DataCenter A -A Master/Consumer in DataCenter B -Replication agreement between both masters, to mirror the directory tree in both environments. Does this sound like a reasonable approach? Is there a better way to do it? (ie: four masters?) Is there documentation for best practices when setting up 389 DS in situations such as this? Thanks.

• How do i cast an object to a string when object is not a string?

  - by acidzombie24

  I have class A, B, C. They all can implicitly convert to a string public static implicit operator A(string sz_) { ... return sz; } I have code that does this object AClassWhichImplicitlyConvertsToString { ... ((KnownType)(String)AClassWhichImplicitlyConvertsToString).KnownFunc() } The problem is, AClassWhichImplicitlyConvertsToString isnt a string even though it can be typecast into one implicitly. I get a bad cast exception. How do i say its ok as long as the class has an operator to convert into a string?

• Cross-browser method for hiding page elements until all content is loaded to prevent layout from appearing broken during load?

  - by Ryan

  I have an issue where due to some elements loading faster than others, the page looks broken for a few seconds at the start. An example is the CSS Pie behavior that allows me to do curved corners in IE, it appears before it becomes curved which looks bad. What would be ideal would be it somehow knowing when everything is loaded and then appear all at once, possibly including some kind of elegant visual way of not making the user feel impatient... any ideas or common tricks for doing this?

• Constructor within a constructor

  - by Chiramisu

  Is this a bad idea? Does calling a generic private constructor within a public constructor create multiple instances, or is this a valid way of initializing class variables? Private Class MyClass Dim _msg As String Sub New(ByVal name As String) Me.New() 'Do stuff End Sub Sub New(ByVal name As String, ByVal age As Integer) Me.New() 'Do stuff End Sub Private Sub New() 'Initializer constructor Me._msg = "Hello StackOverflow" 'Initialize other variables End Sub End Class

• SEO Google - Navigation Title vs. Page Heading

  - by louism

  Hi, i was wondering if anyone knows if theres a connection between what a navigation item is named and the page heading it goes to - does this have an impact on SEO? so for example, if i had in my navigation menu an item called About Us, but when you click it you come to a page with the heading Learn Who We Are (i.e. wrapped in [h1] heading tags) because there isnt an exact one-to-one match, is that a bad thing in terms of SEO? thanks

• Close socket and select()

  - by kamziro

  So I need to close a particular connection, but the problem is another thread is, at the same time, doing a select() which has the socket as one of the file descriptors it's watching. Will the select() terminate gracefully, or will anything bad happen?

• Extend precision of MySQL's double datatype?

  - by tim82

  I am trying to save the value "6.714285714285714" into a DOUBLE datatype field. Unfortunately it does not fit at all and is cutted by one char. Storing larger numbers becomes less precise. Already searched in the mysql manual and it seems to be that double is the most precise data type available. Anyone knows a practicable workaround? Sorry for my bad english and thx a lot!

• Gathering mac addresses with Python

  - by William

  Hi, is there a good way to gather the mac addresses of machines on a local network using Python. If it helps I'm trying to execute this python script from the DHCP server for the network. I'm new to Python but would it be a bad idea to look at the DHCP leases file for this info? I'd like to use this inside a Django app eventually. Thanks.

• What is the best IP/Subnet set up strategy for a multi-server webhosting setup?

  - by Roy Andre

  Sorry for the mixed-up title, but let me try to explain better: We run a hosting solution, which until now has supported shared hosting and VPSes. Easy enough. We are now getting larger clients which require a more complex setup. We have more or less settled the server-setup itself, which will consist of: 1-2 Frontend Proxy/Load balancing servers 2+ Application servers 1 Database server 1 optional Memcached server The issue we are dealing with is to agree on a flexible and easy-to-maintain IP setup. So far we've been into VLAN'ing the internal servers in its own subnet, we've though of assigning an official IP to each server, and so on. What will be the best approach here? Any best practices? Using one official IP on the Frontend server, and then just set up an internal subnet for the servers behind that? We could then just NAT in any eventual sources required to access for instance the DB server directly over 3306.

• What java version is needed for JUnit 4.8

  - by Jens Schauder

  I am trying to run JUnit test with a 1.5 JRE, but get the error Message: java.lang.UnsupportedClassVersionError: Bad version number in .class file When I switch to JRE 1.6 (actually a JDK but that shouldn't matter, right?) everythings works fine. So the questions are: Do we really need Java 6 for the current JUnit version? what is the newest JUnit version, that works with Java 5?

• OpenMP implementations in VC++ 2008, 2010

  - by John

  Depending on implementation, OMP can be quite useful to parallelize fairly arbitrary bits of code - e.g a parallel section inside a method that calls two independent methods - or it can be bad. It depends on how threads are created/cached, I think. How does the VC++ 2008 implementation work? And is the 2010 implementation significantly different in terms of features and performance/flexibility?

• Will Visual Studio 2010 democratize UML ?

  - by asksuperuser

  I've been very upset these past years with all the UML tools (especially the clunky mammoth Rational Rose from IBM which I really hated each time a client asked to use it). I think UML did suffer from bad integration. I rarely used UML myself because of lack of productivity. So I had a positive surprise with Visual Studio 2010 especially the sequence diagram reversing tool which really helps understand code. For people who had tried VS 2010 Ultimate do you think the same ?
