  • Fiber Channel Loop vs Point to Point

    - by RandomInsano
    So, I'm playing with a couple of QLogic QLA2340s connected directly together. I've got options here to either have them act as a loop, or in point to point mode. What's the difference if I'm only going to have two machines connected together? Is point-to-point more efficient? The firmware has an option to prefer loop, then fall back to p2p. Anyone have any idea if there are performance benefits or drawbacks? It's pretty hard to find that information.

  • CentOS vs. Ubuntu

    - by DLH
    I had a web server that ran Ubuntu, but the hard drive failed recently and everything was erased. I decided to try CentOS on the machine instead of Ubuntu, since it's based on Red Hat. That association meant a lot to me because Red Hat is a commercial server product and is officially supported by my server's manufacturer. However, after a few days I'm starting to miss Ubuntu. I have trouble finding some of the packages I want in the CentOS repositories, and the third-party packages I've tried have been a hassle to deal with. My question is, what are the advantages of using CentOS as a server over Ubuntu? CentOS is ostensibly designed for this purpose, but so far I would prefer to use a desktop edition of Ubuntu over CentOS. Are there any killer features of CentOS which make it a better server OS? Is there any reason I shouldn't switch back to Ubuntu Server or Xubuntu?

  • Windows 8 Disk Mirroring vs Intel Fake RAID

    - by Johnny W
    So Windows 8 is out and I have a new motherboard. I wish to create a RAID 1 coupling between two HDDs -- for storage purposes only (my OS is on an SSD) -- but I don't know which is the best route to take. My motherboard (Z77 chipset) comes with the age old Intel Fake RAID, but since I only wish to use my RAID for storage, I wondered if I might be better to use Windows 8 Disk Mirroring. Can anyone advise which is better? Or perhaps the pros and cons of each, if that's too contentious? I just can't see the benefit of FakeRAID. You can see my current setup here, if that might change things(?): Thanks!

  • Unable to generate temporary class for web service

    - by sac
    I have an application with a proxy class for my webservice - This works fine in all 32-bit machines. However the same app throws an exception in windows server 2008 64-bit machine. It looks like the temporary class could not be generated for the web service. The error in the event viewer is "error CS0008: Unexpected error reading metadata from file '' -- 'Bad Key.

  • 50um vs. 62.5um fiber compatability

    - by murisonc
    I've heard that there are compatibility problems when using 50um fiber with some fiber converters. After some research I'm thinking this is a legacy issue when using slower devices (100 Base FX) that used LEDs. I was told that the fiber converters are made for a certain size of fiber core and wont work with 50um fiber. Am I right in thinking this is just a corporate knowledge thing that is outdated when using 1000 Base SX converters (which should be using lasers instead of LEDs)?

  • How to set HTTP Headers from client class inherited from SoapHttpClientProtocol

    - by Alfred
    I'm using a class MyClass inherited from SoapHttpClientProtocol (auto-generated in my project by creating a WebReference from a .wsdl file, representing a service). Before calling a "WebMethod" of this service, I need to custom the http header of my request. I tried overloading the GetWebRequest() method of SoapHttpClientProtocol that way : public partial class MyClass: System.Web.Services.Protocols.SoapHttpClientProtocol{ protected override WebRequest GetWebRequest(Uri uri) { HttpWebRequest request = (HttpWebRequest)base.GetWebRequest(uri); request.Headers.Add("MyCustomHeader", "MyCustomHeaderValue"); return request; } } I was hoping that GetWebRequest was called in the constructor of MyClass, apparently it's not. Could someone help me ?

  • Creating a common selector class with UITableView or UIPicker

    - by trevrosen
    I have several places in my app where I need to select a Foo for further processing from a list of Foo objects. I'd like to do this as a modal view, but neither UIPicker nor UITableView seems to lend itself to the standard approach, since the usual way to do a modal view controller involves setting the parent view controller up as the delegate, and both of those classes need to implement data source protocols, etc. Implementing the data source and selection protocol methods in my parent view controller defeats the purpose of trying to use one common class for implementing this modal selector screen all over my app. Does anyone have any solutions to this problem or am I effectively stuck implementing this selector class over and over again?

  • Home CAT6 wiring: CMR vs CMP?

    - by Eddie Parker
    I'm planning on wiring my house with CAT6 cable. I'm finding a large jump in price between CMR and CMP cabling, and I'm confused by what counts as a 'plenum' and what does not. As I'm wiring my house, I'm planning on going through interior (hollow) walls, and through the attic and crawlspace to get to the points I wish to wire. I will be going between floors at one point, which leads me to believe I need at least CMR, and obviously CMP wouldn't hurt either. I don't mind spending the extra money if I need to, but is it overkill going for CMP if the bulk of the wires are either going vertical, or through a crawlspace or attic?

  • Python-MySQLdb problem: wrong ELF class: ELFCLASS32

    - by jsalonen
    As part of trying out django CMS (http://www.django-cms.org/), I'm struggling with getting Python-MySQLdb to work (http://pypi.python.org/pypi/MySQL-python/). I have installed Django CMS and all of its dependencies (Python 2.5, Django, django-south, MySQL server) I'm trying out the example code within Django CMS code with MySQL as chosen database type When I execute python manage.py syncdb, the following error occurs: django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: /root/.python-eggs/MySQL_python-1.2.3c1-py2.5-linux-i686.egg-tmp/_mysql.so: wrong ELF class: ELFCLASS32 I have been able to trace the problem specifically to python-mySQLdb (as also visible in the stack trace). Other than that, I am completely puzzled. I don't have a clue what ELFCLASS32 means, or what ELF class is anyway. I suspect that this error could have something to do with the fact that I am running 64-bit version of Debian 5 (on a VPS). Any good ideas how to troubleshoot?

  • Windows 7 Disk Management Spanned Volume vs Striped Volume

    - by Kairan
    Im looking for a reason why a person would use a Spanned volume rather than a Striped volume? If my understanding is correct Striped: Faster read/write speed than spanned, but I "assume" more wear+tear Spanned: No speed benefit like striped, but data is written sequentially and fills up Drive1 before filling up Drive2, so it saves on wear+tear Beyond that Im not sure if there is any other deciding factor on which to use. Definition found below: A striped volume uses the free space on more than one physical hard disk to create a bigger volume. Unlike a spanned volume, a striped volume writes across all volumes in the stripe in small blocks, distributing the load across the disks in the volume. The portions of disk used to create the volume need to be the same size; the size of the smallest free space included in the striped volume will determine.

  • Using terminal vs KDE in linux?

    - by Ke
    Hi Im used to using nautilus within centos but have recently just got a VPS and quickly realising that using a KDE is unacceptable in this environment. Although I do find it so much quicker doing things like folder permissions in KDE rather than typing it all out in the terminal? Everyone I speak to says, use the terminal and I should learn this way as opposed to using the KDE, but theres certain things I just dont get How is it possible to make quick changes to scripts and viewing them in a browser etc , without a mouse or using KDE? and only using a terminal?? I am wondering how to develop websites just using the terminal??? How can it be quicker to type out/view permissions etc in the terminal when its instant and just a few clicks in the KDE? Any thoughts are much appreciated. I would love to understand the benefits but just cant seem to see them right now. Cheers Ke.

  • Removable vs fixed mount points in Linux

    - by Dave
    What makes a mount point removable in Linux? I am using Gentoo Linux with Gnome 3.2, and I find it annoying that some of my drives (ex: /dev/sdb) appear as removable but not the others (ex: /dev/sdc, /dev/sdd). They are all in /etc/fstab, with the same options. They are all mounted properly at startup, they all work fine under my own folders /mnt/drive2 /mnt/drive3 /mnt/drive4. But only one of them (the first) appears in Nautilus (and in the Gnome 3 notification tray) as mountable/removable, not the others. Can I add options to my fstab to hide it? Or can I probe using udevadm or whatever? It looks strange to be able to remove/unmount fixed drives that I never need to unmount nor remove. Any pointer would be good, thanks.

  • Python 3.1.1 Class Question

    - by Protean
    I'm a new Python programmer who is having a little trouble using 'self' in classes. For example: class data: def __init__(self): self.table = [] def add(self, file): self.table.append(file) data.add('yes') In this function I want to have table be a variable stored in the class data and use add to modify it. However, when I run this script it gives me the error: Traceback (most recent call last): File "/Projects/Python/sfdfs.py", line 7, in <module> data.add('yes') TypeError: add() takes exactly 2 positional arguments (1 given) I assume that I am trying to call the function the wrong way in this instance, as this syntax is very similar to an example in the python documentation: http://docs.python.org/3.1/tutorial/classes.html

  • Dell R510 vs R710

    - by AX1
    Hello, the Dell R510 and R710 can both hold regular configurations (e.g. X5650, 24 GB RAM, etc.) and these usually come out to about the same price. Is there a particular reason why one would choose the R510 over the R710 or vice versa? There really appears a lack of differentiating factors. The only 'major' factor I found, which doesn't apply to me though, is that the R510 can hold up to 12 3.5in HDDs while the R710 (which is slightly more expensive) can only hold up to 6 3.5in HDDs. Maybe you guys have some input and bought either of these machines (or both) to shed some light on other differences and why someone should choose one over the other as the pricing is pretty much the same with my configuration. Thanks!

  • apache rewrite debian vs windows

    - by user1079002
    I have simple rewrite rules as I just learned about them RewriteEngine On RewriteRule ^dl/(.*)/.*$ dl/$1/index.php [L] RewriteRule ^index.php$ upload.js [L] both are working on Windows for url localhost/upload/dl/mkdji/index.php, but on Debian works only second rule for url www.domain.com/index.php, but not for www.domain.com/dl/oksoks/index.php After dl is some random string. Obviously I'm missing something regarding directory depth, but don't know what. file htacces is in localhost/upload and root of domain.com folders. What am I missing here?

  • i5 vs. i7 processor dev laptop

    - by vector
    Greetings! I need to get a laptop for dev work ( mostly server side Java, NetBeans ) and wonder if anyone had a chance to use either the i5 or i7 based laptop? Is the i7 an overkill? ... or will the i5 handle it just fine? I'm thinking something from the HP line running Ubuntu. Thanks

  • Difference between "Redirect permanent" vs. mod_rewrite

    - by Stefan Lasiewski
    This is an Apache httpd 2.2 server. We require that access to this webserver be encrypted by HTTPS. When web clients visit my site at http://www.example.org/$foo (port 80), I want to redirect their request to the HTTPS encrypted website at https://www.example.org/$foo . There seem to be two common ways to do this: First method uses the 'Redirect' directive from mod_alias: <VirtualHost *:80> Redirect permanent / https://www.example.org/ </VirtualHost> Second method uses mod_rewrite: <VirtualHost *:80> RewriteEngine On RewriteCond %{HTTPS} off RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} </VirtualHost> What is the difference between a "Redirect permanent" and the mod_rewrite stanza. Is one better then the other?

  • Windows Server 2008 Standard vs. Web

    - by Andreas
    I'm currently comparing Windows Server 2008 versions to see what to use. What i found is this, that might affect me: RAM: 32GB. (the same) Sockets: 4 (the same) Remote Desktop: 2 (the same) IIS: true (the same) Application Server: Only standard. I will run my server as a single CPU (4 core) 8GB RAM, 2x raid1 web-server running: IIS Asp.net .Net 4 Third part mail server. (Only for sending mail from my web-application) SQL Server Express (My data is not more then 10 GB) Some minor applications for import and export of data. I might use external load balancer if I install a second machine in the future. My question is if you see any reason for me to go for standard that is 4 x price compared to web. BR Andreas

  • Intel z77 vs h77 for intensive compiling, gaming [closed]

    - by Bilal Akhtar
    I'm in the market for a desktop motherboard (preferably ATX) that functions well with Intel i7-3770 Ivy Bridge processor at 3.4 GHz with LGA1155 socket. That processor is very fast, and it should handle all my tasks. My question is about the type of motherboard chipset I should choose to accompany it. I plan to use my rig for compiling and developing Debian package and other OS components, web development, occasional Android apps, chroots, VMs, FlightGear, other gaming but nothing serious, and heavy multitasking, all on Ubuntu. I do NOT plan to overclock, and I never will, so that's not a cause of concern for me. That said, I'm down to three chipset choices: Intel H77 Intel Z68 Intel Z77 I'm planning to go for H77 since I don't need any of the new features in Z77. I don't plan to use a second GPU and I will never overclock my CPU/GPU. My question is, will H77 based MoBos handle all my tasks well? Intel advertises that chipset as "everyday computing" but other sites say it's base functionality is the same as Z77. Intel rather advertises Z77 for "serious multitaskers, hardcore gamers and overclocking enthusiasts". But the problem with all Z77 motherboards I've seen is, they're way too expensive and their main feature seems to be overclocking, which won't be useful to me. Will I lose any raw CPU/GPU performance or HDD R/w with the H77 when comparing it to a Z77? Will heat, etc be an issue too? From what I've seen, Z77 motherboards have larger heat sinks when compared to H77 ones. Will that be an issue too, if I go with an H77 motherboard with no heat sinks for the chipset? The CPU will have a fan in both cases, of course. tl;dr When it comes to CPU/GPU performance and HDD r/w, is the Intel H77 chipset slower than the Z77? I don't care about overclocking or multiple GPUs, and for the processor, I'm set on Ivy Bridge i7-3770.

  • LVM2 vs MDADM performance

    - by archer
    I've used MDADM + LVM2 on many boxes for quite a while. MDADM was serving for both RAID0 and RAID1 arrays, while LVM2 where used for logical volumes on top of MDADM. Recently I've found that LVM2 could be used w/o MDADM (thus minus one layer, as the result - less overhead) for both mirroring and stripping. However, some guys claims that READ PERFORMANCE on LVM2 for mirrored array is not that fast as for LVM2 (linear) on top of MDADM (RAID1) as LVM2 does not read from 2+ devices at a time, but use 2nd and higher devices in case of 1st device failure. MDADM reads from 2 devices at a time (even in mirrored mode). Who could confirm that?

  • PHP vs Batch file for mysql cronjob?

    - by mysqllearner
    Hi, My server details: OS: Windows Server 2003 IIS6 Plesk 8.xx installed (currently using Plesk to set the cronjob) I need your advice. I have 2 methods: Method 1: Using php + mysqldump, create databases backup files into gzip, and then send email with attachment (each databases has around about 25mb) Method 2: Using batch + mysqldump, create databases backup files into gzip, and then send email with attachment (same, each databases has around about 25mb) My questions: Whats the difference of using php file and batch file for cronjob? Which method is better in term of backup speed and send email, and (maybe)safety (e.g., lesser file corrupt occurance)? If i set the cronjob hourly, will it effect my web performances? I mean, lets say my website has 100++ users online now, and each user making transaction to MySQL, when I perform backup at my web peak hour, will it decrease the performances, like the loading speed, prone to errors etc?? (sorry for my bad english) P.S: If you need my php and batch file code, please ask me to post it here. I didnt post it now is because, its very simple and standard code.

  • key value coding-compliant for NSObject class?

    - by 4thSpace
    I've created a singleton class that loads a plist. I keep getting this error when I try to set a value: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key test.' I have one key in the plist file. The key is named "test" and has no value associated with it. I set the value like this: [[PlistManager sharedManager].plist setValue:@"the title value" forKey:@"test"]; I look at the set plist dictionary and see this from within PlistManager: po self.plistDictionary { test = ""; } I get the error just as I'm leaving PlistManager in the debugger. PlistManager is of type NSObject. So no xibs. Any ideas on what I need to do?
