How to update iOS on your iPhone, iPod Touch or iPad

I couldn’t find anything similar on Apple’s support site, so I thought I’d do up a quick tutorial for iPhone, iPod Touch or iPad users who have no idea how to go about getting the latest and greatest software updates on their devices. šŸ™‚ In this tutorial, we are updating an iPhone to iOS version 4.3.4 Step 1 Launch iTunes on your computer and connect your iPhone, iPod Touch or iPad to your computer using the cable. Step 2 In iTunes locate your iPhone under DEVICES Step 3 At the Summary screen, click on Update. Step 4 Click on Update again at this new dialogue box. Step 5a Click on Next etc throughout. Step 5b The software update will start downloading. This may take a while depending on the speed of your internet connection and the size of the...

KnowledgeTree speed on VPSes

KnowledgeTree speed on VPSes

I was trying out KnowledgeTree 3.7.0.2 (Community Edition) on 3 different virtual private servers just to see how they fareĀ  with “heavy” websites, and here’s how they perform generating a page of 20 items. All VPSes are 512MB instances running on Ubuntu 10.04 LTS . APC Hosting (Virtuozzo) Request created in 17.190s Rackspace Cloud Server (Xen) Request created in 0.446s Club Uptime (OpenVZ) Request created in 0.299s The most ironic thing is that the above VPSes are listed in order of most expensive to least expensive. It seems here we do not get the best performance from the mostĀ  expensive service? In fact it performs much worse than the other two! At this point, the Rackspace offering is the most attractive with its built-in manual and...

Debian Lenny to Squeeze upgrade

Debian Lenny to Squeeze upgrade

Debian 6 i.e. “Squeeze” was released almost a month ago. Although there are still about 11 months more before Debian 5 “Lenny” is no longer supported, I figured I would upgrade one Debian Lenny Xen-based VPS hosted on a Rackspace Cloud,Ā  currently functioning as an OpenLDAP server, as a weekend project. The upgrade steps were straightforward: 1. Edit /etc/apt/sources.list and change all instances of lenny to squeeze. 2. Run the following commands in succession in terminal sudo apt-get update sudo apt-get install apt dpkg aptitude sudo apt-get dist-upgrade Surprisingly enough the upgrade went well with Apache and even OpenLDAP migrated successfully. Just the following issues related to phpldapadmin were encountered: 1. The upgraded...

Unattended updates on CentOS

Unattended updates on CentOS

Having recently had to clean up after the Exim4 vulnerability that did not get patched on a server in time, one of the first things I do on a new VPS is set up automatic unattended updates. The steps are clearly documented for Debian/Ubuntu, but for CentOS it was a little harder to find the information. Here are the steps: In a terminal session run yum install yum-updatesd Next you need to edit /etc/yum/yum-updatesd.conf and edit the following lines to hold the values in bold emit_via = email # automatically install updates do_update = yes # automatically download updates do_download = yes # automatically download deps of updates do_download_deps = yes and also enter the following lines # who to send the email to: email_to = myself@myemaildomain.com # who send...

WordPress updates without FTP login prompts

WordPress updates without FTP login prompts

One gripe I have about running WordPress on a VPS is that it keeps prompting me to enter the FTP password every time I do an update. As it turns out, you can save your FTP login credentials in wp-config.php so that you never get asked again! Simply add the following lines to wo-config.php // ** FTP SETTINGS FOR AUTO-UPDATE ** // define('FTP_HOST', 'YOUR-HOSTNAME-HERE'); define('FTP_USER', 'YOUR-FTP-USERNAME'); define('FTP_PASS', 'YOUR-FTP-PASSWORD'); Remember to change the values above accordingly.
