  • Best Linux Distro for web services (Nginx & node.js) on laptop: Compaq 6710b?

    - by tomByrer
    I haven't used Linux in 5+ years, aside from d/l occasional system recovery CDs off DistroWatch, so I don't know the current landscape. Related postings on this forum are several years old & may not relate to my hardware (Compaq 6710b laptop, Core2Duo Centrino). Requirements: Use the Compaq 6710b laptop's WiFi out of the box enough frequently updated pre-made packages for web hosting & development (Nginx & node.js are biggest concerns, everyone has Apache & PHP, & I'm not crazy about building from source) prefer be easy enough to use, but outside help available (so a small user-base distro is only OK if the community is active & a major disto's packages are compatable) configuration easy to transfer to outside web hosts. You have actually installed/used recommended disto (don't have to be expert) TIA!

  • centos server shared files

    - by Kyle Hudson
    Hi, I am wanting to implement a multi-server specialised hosting environment. I currently have a cloud solution comprising of 3 centos boxes (2 lamp web servers, 1 mysql). What I am wanting to do is, implement a 5 server solution where they is 3 web servers, 1 mysql box and a fileshare. Basically I want the fileshare to host all the web files for the servers, the caching will remain on the individual servers and the sessions will be stored in mysql. So what I am asking is how do I map the servers to share the same "docroot"? Is it NFS? if so whats the best way about doing this? Thanks in advance.

  • Is HTML considered a programming language?

    - by nihilist.myopenid.com
    I guess the question is self-explanatory, but I'm wondering whether HTML qualifies as a programming language (obviously the "L" stands for language). The reason for asking is more pragmatic—I'm putting together a resume and don't want to look like a fool for listing things like HTML and XML under languages, but can't figure out how to classify them.

  • Will this SPF record restrict delivery of email for the original domain?

    - by user199421
    As part of the product we offer we send emails on behalf of our clients. Because the emails don't come from an IP associated with the client they are sometimes flagged as spam. We advised some of our clients to add an SPF record approving us to send emails on their behalf. We saw immediate improvement in deliverability rates after making the change however one of our clients was notified by his hosting provider that the SPF record we suggested to add would "slightly restrict" all emails that don't come from our servers (including our client's own servers). The record we use is this: v=spf1 a mx include:ourdomain.com ~all So my question is if the warning we received about this is correct and if so why and what can be done to solve this (allow sending email both from original domain and by ourselves).

  • Bringing the xenbr0 interface up on XEN under Ubuntu 8.04

    - by iyl
    I installed XEN on Ubuntu 8.04 using this tutorial: http://www.howtoforge.com/ubuntu-8.04-server-install-xen-from-ubuntu-repositories but after I reboot with the XEN kernel, I don't have xenbr0 device. I see that network-bridge script runs and it creates peth0 device, but not xenbr0. I have a very basic IP setup, with a single static IP defined in /etc/network/interfaces. The only unusual thing is that my hosting (1&1) gave me a netmask 255.255.255.255, so I had to add the default gateway with this script: /sbin/route add -host 10.255.255.1 dev eth0 /sbin/route add default gw 10.255.255.1 Everything else is plain vanilla Ubuntu 8.04.

  • basic help for Nat configuration needed

    - by Klaes S.
    I have a server with a IP 1.0.0.5/24. This is the main IP address of the server, and now I have two other IP addresses for the server, they are 1.0.2.30/24 and 1.0.2.31/24. I want to make a VirtualBox running another OS accessible through the Internet, and only allow the specified IP to reach the virtual box. I'm new to iptables and therefore I need some basic help and getting started information about this. The hosting provider does not allow more than on MAC address per switch port, which means that I'm not able to make bridge as far as I know. Futhermore I want the host, to reject the extra IPs so its only the VirtualBox / virtual machine that accepts the request's on the extra IPS.

  • Application deployment with Puppet

    - by michaeltwofish
    I'm new to Puppet and while I've been using *nix systems for many years, I've never worked as a sysadmin or in ops. I'm currently writing Puppet manifests for hosting a set of (PHP/MySQL/MongoDB, code in git) web applications. Clearly Puppet needs to have some knowledge of the actual applications because I'll set up a virtual host for each one, but I'm not sure whether Puppet should be managing things like code deployment and database creation. Is Puppet an appropriate tool for application deployment? If not, can you recommend a more appropriate tool?

  • Building a balanced binary search tree

    - by Znarkus
    Hi! Is there a method to build a balanced binary search tree? Example: 1 2 3 4 5 6 7 8 9 5 / \ 3 etc / \ 2 4 / 1 I'm thinking there is a method to do this, without using the more complex self-balancing trees. Otherwise I can do it on my own, but someone probably have done this already :)

    I have a iAd that seems to be correctly displaying but when push a new view controller into the view i get a warning from the iAd that says it has been: WARNING A banner view (0x490fd0) has an ad but may be obscured. This message is only printed once per banner view. But the ad still runs fine so should i pay attention to this? I just tried adding self.adBannerView = nil; [adBannerView release];` just before i push the viewController but i still get that error

  • Should the hostname of my VPS point to the dedi IP of my Domain or to to a shared one used for new account creation?

    - by thomas
    I leased a VPS which I want to use to sell shared hosting. 3 IPs - I call them A, B and C here for simplicity. Actual setup is: A=NS1.mydomain.com; host.mydomain.com and is used to set-up new accounts in shared environment B=NS2.mydomain.com C=dedicated IP for mydomain.com (SSL secured) The more I read about DNS, the more I get confused; thus my question: Is this configuration "Good Practice", especially the hostname pointing to A rather than to C? And what would be a better alternative?

  • How to tell IIS7 to allow POST to a text file (to solve 405)?

    - by meticulous
    If I want to allow HTTP POST to text files *.txt (i.e. I'm taking an example of what could be any static resource normally accessible by GET). The error is: Server Error 405 - HTTP verb used to access this page is not allowed. The page you are looking for cannot be displayed because an invalid method (HTTP verb) was used to attempt access. How can I accomplish this? Background: I'm using apps.facebook.com to hit my hosted facebook app and facebook sends HTTP POST now through to the iFrame hosting my app. This facebook behaviour has been around for a while but it's being forced now. In turn this forces me to make stuff available to the POST verb.

  • General question about Ruby Eigenclass/Singleton

    - by Dex
    module MyModule def my_method; 'hello'; end end class MyClass class << self include MyModule end end MyClass.my_method # => "hello I'm unsure why "include MyModule" needs to be in the eigenclass in order to be called using just MyClass. Why can't I go: X = MyClass.new X.my_method How is this type of pattern useful if I can't call it from an instance?

  • How to find out if a method exists in Obj-C when given an NSString

    - by Justin
    I have a method as an NSString *. If it exists, I want to call it, and if not, do nothing. SEL eventSelector = NSSelectorFromString(eventSelectorStr); if ([delegate respondsToSelector:eventSelector]) { [delegate performSelector:eventSelector]; [delegate adapterDidFinishAdRequest:self]; } else { // Does not implement selector } This code does not work, since NSSelectorFromString will register the string as a selector, so respondsToSelector:eventSelector will cause a crash because the selector is actually invalid.

  • Python List length as a string

    - by mvid
    Is there a preferred (not ugly) way of outputting a list length as a string? Currently I am nesting function calls like so: print "Length: %s" % str(len(self.listOfThings)) This seems like a hack solution, is there a more graceful way of achieving the same result?

  • Using git with cgit for decentralized/centralized development

    - by polemon
    I plan to use git for hosting my projects on my server. I've read about cgit, git-daemon, and I more or less decided to use those tools. But general use is still kind of confusing for me. What do I need to set up on the server, to push my files onto it. And when the files on the server are newer as the files on my computer, how do I merge them? Also, I use, say, two computers where I develop. How do I merge from one computer to the other? Also, when two people are working on the same project, how do they merge their local repos from one another? As you probably can tell by now, I come from SVN, but I've worked with Mercurial and now I'd like to test git.
