However, I had a problem with MAMP and a vhost I setup for local development. The wordpress front page and /wp-admin/ worked but any sub pages, etc. failed to load. When trying to access a WordPress page at url http://site.local/music/ The error in the apache logs was:

[error] [client 127.0.0.1] File does not exist: /Users/lantrix/devel_projects/vhosts/site.local/music

I had made sure that mod_rewrite was enabled as mentioned by Samuel B over at the WordPress support forums. I had also ensured I had updated the permalinks in the local WordPress install, thus writing out a .htaccess for the rewrites. Still no luck.

Then I remembered, one needs to tell Apache that a directory outside the webserver root /Applications/MAMP/htdocs, in this case my vhost path of /Users/lantrix/devel_projects/vhosts/site.local, needs to have an AllowOverride so the .htaccess WordPress has placed can be used. This in combination with the apache Options directive to FollowSynLinks as mentioned by Mark at the support forums worked for me. No more 404 errors!

Below is my working vhost configuration at the bottom of my MAMP apache config file /Applications/MAMP/conf/apache/httpd.conf. It works for me, but YMMV:

A Ruby

If you’re a tech head, and you’ve been around Object Orientated languages – then you’ve surely heard of Ruby.

I’ve been around people who are passionate about Ruby, but never caught the bug. What I did do whilst others were programming away, was read about ruby. One day whilst reading I came across the name of an online persona Why the lucky stiff, also known as _why.

_why

Whilst _why was/is considered a prolific and influential programmer of Ruby, what was fascinating was his disappearance. In August 2009, he withdrew from “public” life – specifically all his online presence was deleted. He closed up his blog, twitter account and github account. Plenty of people have ensured his code and writing not only live on but continue, and you can read more of his eccentric writings at his estate.

However, my interest here is his book: Why’s (poignant) Guide to Ruby

Some have innocuously declared the 19th of August as “Why Day“. What better way to celebrate knowledge than to start reading a book, and why not read the guide book itself?! I’m just a regular old person, so far unaware of Ruby and its intricacies. I may even be able to teach a child what I learn.

I declare that starting from August, and thanks to #whyday, I’ll start reading his guide to Ruby – hence furthering my limited knowledge of Object Orientation in programming. At least once a week I’ll write something I’ve learnt about Ruby, because _why once tweeted “programming is rather thankless. you see your works become replaced by superior works in a year“. Hopefully what I write will be thanks.

I’ll leave you with another quote from _why that used to be at the front of his code repository for Ruby: “If you are just a regular old person unawares, I still believe that great things can come from you, but only if you will just leave this place immediately and begin your quest to invent a machine for turning pure kinetic energy into animals.”

I first saw this video at Eastman’s Genealogy website.

Original research of the figure and facts is by Karl Fisch, Scott McLeod, and Jeff Brenman.

One of the initial mistakes I made was to try and run the installation from a network mount. DON’T. Solaris must block the execution of code on some types of removable drives, which in this case was a VMWare Fusion shared folder.

A second thing that is not clear in the README files: Clearcase 7.1.1 on Solaris x86 does NOT support the GUI installation. Therefore, for me as much as any readers of this blog, I’ll document the steps to kick off a fresh/silent installation.

The install will be/have:

• A local install
• Clearcase Atria Licencing, local
• IBM Installation Manager installed first
• ClearCase installed second

1. Download your entitled product for Solaris X86, for CC7.1.1 which is:
   • CZ9XKML
   • IBM Rational ClearCase V7.1.1 Solaris x86 Platform Edition Multilingual

   If you need an evaluation copy, they are also available.

2. Copy the archive to your server, and extract it. I’ll use /var/ccinstall for my install source, but adjust as required:
   

   
   mkdir -p /var/ccinstall
   cp -p CZ9XKML.zip /var/ccinstall
   cd /var/ccinstall
   unzip CZ9XKML.zip
   cd disk1
   

3. Follow the IBM documented steps for preparing a silent install. For my steps the dir /var/ccinstall/disk1 will be esd_image_root.
4. Kick off the install:
   

   
   /var/ccinstall/disk1/InstallerImage_*/install \
   --launcher.ini \
   /var/ccinstall/disk1/InstallerImage_*/silent-install.ini \
   -silent \
   -input clearcase_response_sol_x86.xml \
   -log silentinstall.log
   

   
   If you want to also show the progress, include the switch -showVerboseProgress

At this point kick back and make a few coffees.
Enjoy.

OpenBSD v4.7

OpenBSD is a multi-platform 4.4BSD-based UNIX-like operating system, and is fast, simple to install and secure “out of the box”.

1. Download installation files
2. Read the Installation guide
3. Read the Frequently Asked Questions

A good introductory book for OpenBSD is the “OpenBSD Command Line Companion” by Jacek Artymiak. It walks you through an install and an intro to OpenBSD.

Other books on the OS are:

• Absolute OpenBSD: UNIX for the Practical Paranoid
• The Book of PF: A No-Nonsense Guide to the OpenBSD Firewall

one of my external hard drives, the one with EVERYTHING I REALLY, REALLY WANT on it has died…

Im sure this happens to many people, and often. What is one to do in a case like this?

Did you backup?

• OPTION 1: If it’s your backup drive that failed, the data will most likely still be on the related computer. Make another copy or backup. Problem solved.
• OPTION 2: If it’s not a backup drive that failed, do you have a backup of it? If not start backing up in future. Think about your recovery options, and the cost involved.

Data recovery options

Ok so you didn’t have a backup, and it’s critical data. If you manage to recover your data, you should consider that prevention is better than a cure.

• OPTION A: If it’s a mac, I use and can recommend Data Rescue by Prosoft Engineering. This software allows you to recover data from the HDD and costs about USD$100. You will need another external HDD (preferably two to clone your corrupt drive first) to recover data to. DON’T use the broken hard drive until the software and new HDD(s) are ready to go. This will cost about $300 for two new disks and the software but has no guarantee it will work, especially if there has been a catastrophic hardware failure.
  • if it’s windows, I can’t and/or wont be able to help or give free advice. Try a windows data recovery program as per option 3. If you want to engage the services of a professional to recover on windows expect $150 per hour.
  • Is it Linux, BSD or UNIX? If you disk is unmounted then try fsck -fy <yourdiskdevicename>
• OPTION B: Pay a professional data forensic service company upwards of $1000 to recover your data. Some companies, such as Prosoft Eng, may perform this task at a budget rate.

How much is the data worth to you?

If it’s not worth between $300 (for the software + new disk solution) to $1000+ then a last ditch effort is put the HDD in the freezer for 10 mins and see if it works long enough to get your essential data off it. Freezing it may permanently destroy the disk so I accept no liabilty for offering this advice.

Future prevention

Disks fail, it’s just a matter of time as to when. Always have at least one backup of ALL your data you can’t afford to lose. On a Mac, it’s as simple as buying an external disk that is about 1.5 times the size of your computers Hard drive, and plugging it in. The Mac will ask if you want to start backing up – and all you have to do is leave it plugged in when you use your Mac.

Even better is to backup in duplicate or triplicate with a copy “offsite“, e.g. at another location. Update backups regularly, with time between backups as long as you an afford to miss data. On a Mac, you can have one hard drive always plugged in, backing up with Apple’s Time Machine. Introduce a second Hard drive that you “clone” once a week using Carbon Copy Cloner, and leave that drive locked up at work. Now you have a primary backup and an offsite secondary backup.

Use paid “cloud” backup services such as dropbox (which I use for free), mozy, BackBlaze or iDrive. These will sync or backup your valuable data automatically into the “cloud”, and even in some cases between computers.

Good luck!

I have previously setup the port forwarding, etc. according to Apple, but never could get a successful connection using video or audio (or screen sharing).

After reading a post on the OpenBSD misc mailing list I went back and read the OpenBSD 4.5 pf.conf man page.

There is a section of the man page that states (my emphasis):

fragment reassemble
Using scrub rules, fragments can be reassembled by normalization.
In this case, fragments are buffered until they form a complete
packet, and only the completed packet is passed on to the filter.
The advantage is that filter rules have to deal only with complete
packets, and can ignore fragments. The drawback of caching frag-
ments is the additional memory cost. But the full reassembly
method is the only method that currently works with NAT. This is
the default behavior of a scrub rule if no fragmentation modifier
is supplied.

My scrub settings were such that I was filtering not complete packets, but fragments. The moment I changed the scrub settings to this:

scrub in on $ext_if all fragment reassemble

All worked perfect. I can initiate iChat calls and receive them too. Desktop sharing now works as well. All using Google talk (jabber) in iChat.

Note that in OpenBSD 4.6 or current there have been PF changes, so the wording of the scrub rule may be different. Always read the pf.conf man page for the release you are on.

Initialized empty Git repository in /Users/lantrix/tweet/.git/
Using higher level of URL: http://plugins.svn.wordpress.org/tweet => http://plugins.svn.wordpress.org

And it would proceed to hit up the entire wordpress repo.
After reading a possible solution on Charlie’s Old blog, I stubmled across a newer way to do this.

As of v1.6.4 of git, you can now use a –no-minimize-url when doing a git-svn clone. This makes git clone only the part of the repo you want; and the added bonus is you can get all your tags and branches.

Here is how I did it:

git svn clone --prefix=svn/ --stdlayout \
--authors-file=authors.txt \
--no-minimize-url http://plugins.svn.wordpress.org/tweet/

It still took a while to parse all the SVN history, and now of course this stands out in the git-svn doco

The authors.txt file just mapped my svn users to git user/email pair, e.g.:

lantrix = Lantrix <lantrix @someemail.com>
plugin-master = none <none @none.com>
(no author) = none </none><none @none.com>
</none></lantrix>

You will probably want to have a look at these set of scripts. Have a read of NothingMuch’s perl blog for extra steps and details on extra svn conversion scripts.

I’ve also customised the PS1 to show user/host/path.

You should probably setup git bash completion as well. This can be done by sourcing the bash completion script that is available in the git source code as shown (change path to where you place script):

Have fun.

If you are working in Excel, and you want to show the worksheet name in a Cell on that worksheet, you can use the CELL function to do so.
By default the CELL function will return the current document name, if used with the filename info_type:

=CELL("filename")

This provides a full path to the spreadsheet, with the worksheet of the current Cell at the end, e.g:

C:\folder\[myfile.xls]Sheet1

You can easily get just the worksheet name by using the FIND and MID functions to do the hard work. You need to find the location of the last square bracket, and find achieves this as shown:
=FIND("]",CELL("filename"))

This would return the position of the last bracket. In this case it is at position 22 of the text that CELL(“filename”) returns. The MID function can extract text starting at a location for n length, where n is an arbitrary number. So we would combine MID, FIND and CELL functions to return just the worksheet name like this:

=MID(CELL("filename"),FIND("]",CELL("filename"))+1,255)

The reason we add a +1 is because we want to start extracting the text one character AFTER the right square bracket, e.g. at the start of the Worksheet name. Our result is:

Sheet1

Worksheet names from another Worksheet

So far so good, and how is this any different than any other blog post or forum post on the net explaining this? So far it’s not, but here comes the fun part.

What if you have multiple Worksheets, and you do this:

1. Have a cell with content, Sheet1!B2
2. Sheet1!B2 displays the content of OtherSheet!H5, i.e.:
   

   =OtherSheet!H5

3. You want Sheet1!B1 to display the worksheet name where the CONTENT of Sheet1!B2 comes from.

You could try using the MID/FIND/CELL function combination to try this. In Sheet1!B1 you would enter:

=MID(CELL("filename",B2),FIND("]",CELL("filename",B2))+1,255)

However this would yield the worksheet name of B2 itself, not the worksheet where you are taking your content from:

Sheet1

Not what we wanted. Somehow you need to get the Value of the formula used =OtherSheet!H5 and look up the worksheet name for OtherSheet!H5

The Solution

To do this you ware going to need to do two things:

1. Make a new function to display the formula, sans the equal sign
2. Make your CELL function use the result of your function to lookup the filename info_type

We can use the Excel VB Editor to create a new function, and call it GetLocation:

Function GetLocation(Cell As Range) As String
   GetLocation = Mid(Cell.Formula, 2)
End Function

But we can’t just use GetLocation to directly feed the CELL function. We need to use another handy function INDIRECT. This allows us to return the result of the GetLocation function as a Reference. This then allows the CELL function to evaluate the filename/Worksheet details for the destination cell in the other worksheet:

=MID(CELL("filename",INDIRECT(GetLocation(B2))),FIND("]",CELL("filename",INDIRECT(GetLocation(B2))))+1,256)

This now provides the Worksheet name of the cell that Sheet1!B1 is using to get it’s content from which is OtherSheet!H5:

OtherSheet

This is very handy when you need to show on a master worksheet which other worksheet your data is actually coming from. Windows Excel only, not Mac I’m afraid – until they bring back VB. Enjoy!

In my case I am Using Solaris 9, and have Oracle 10g databases and client files for use by BOE.

When running the cmsdbsetup.sh script you get the following error pertaining to clntsh:

           Business Objects 

Current CMS Data Source: DBNAME 

err: Error: Failed to get cluster name. 
err: Error description: Unable to load clntsh 

select (Select a Data Source) 
reinitialize (Recreate the current Data Source) 
copy (Copy data from another Data Source) 
changecluster (Change current cluster name) 
selectaudit (Select an Auditing Data Source) 

[select(6)/reinitialize(5)/copy(4)/changecluster(3)/selectaudit(2)/back(1)/quit(0)] 
----------------------------------------------------------

This error “Unable to load clntsh” refers to the libclntsh.so library used by the Oracle client. Since BOE runs as 32bit, the 32bit Oracle client libraries should be accessible by the user running BOE.

If you are running a 64 bit Unix and a 64bit Oracle install check that the environment for the user running BOE (user that will run the CMS) has the 32bit libraries in the path:
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib:$ORACLE_HOME/lib32

Then check that either the user is a member of the Oracle dba Unix group or everyone has permissions to access the 32bit libraries under Oracle 10g:

su - oracle
chmod o+rx $ORACLE_HOME/lib32/*

Feel free to leave any comments if you need help with this.

Many people sent suggestions to Apple to fix this, but it seemed to be falling on deaf ears.

Little did we know that Apple were releasing a new version of the touchpad driver included with Bootcamp 3.0 on the Snow Leopard install DVD.

I’ve updated my Bootcamp to 3.0, and indeed the applemtp.sys driver version has increased to 2.1.2.112. The FAQ for the Snow Leopard update states that Bootcamp 3.0 has:

“Improved tap-to-click support – The ability to tap the track pad to click the mouse button is now supported on all Mac portables that run Boot Camp.”

In my tests, so far, there has been no more crashes. I get to use double finger right click tap, and the track pad responsiveness that I got in the older buggy driver is back as well.

Thanks Apple. No more BSOD.

• Vendor: Novatel Wireless Inc.
• Model: GSM
• APN: 3netaccess
• CID: 1

I installed Snow Leopard as an Upgrade (not a fresh install) after having a CCC backup and a Time machine backup in place.

When I plugged in my 3 expresscard, 10.6 detects the card, initialises and populates the WWAN icon with “Telstra 3G: Not Configured”.

It detects the card as a “Novatel Wireless HSDPA Modem”, and automatically configures the Network Advanced settings of the card, as shown:

The question is: Why is the APN telstra.datapack setup as default?

I am able to change the APN to 3netaccess, which results in a successful connection to 3:

The annoying thing is the WWAN menu still shows Telstra when connected.


Looking at the WWAN system file:

cd /System/Library/Extensions/IOSerialFamily.kext/\
Contents/PlugIns/AppleWWANSupport.kext/Contents/\
Resources/
less countryCodes.plist

First off install some require packages, including the zziplib package:

  export PKG_PATH=http://mirror.aarnet.edu.au/pub/OpenBSD/4.5/packages/i386/
  pkg_add -v zziplib
  pkg_add -v autoconf-2.62

  mkdir /usr/local/src/
  cd /usr/local/src/
  wget http://pecl.php.net/get/zip
  tar zxvf zip
  cd zip-1.10.2/ 

  export AUTOCONF_VERSION=2.62
  phpize
  ./configure
  make
  make install

  cat << EOF >> /var/www/conf/php.ini
  extension=zip.so
  EOF
  sudo apachectl stop
  sudo apachectl start

Of course, this will go stale over time as new releases and versions come out, so YMMV.

Todays post is a 2009 midyear round up of the status of the Google Mobile applications: Latitude, Voice, Docs, Mail, Maps and Reader. My focus is on the iPhone mobile platform.

• Google Latitude

  Google Latitude is their location and status message product. The application up until now has been available on other phone platforms such as Android, but lacking on iPhone.

  In the mean time, iPhone users have had to look elsewhere. There are other similar products that perform locational “check-ins” and integrate with services such as Twitter. Brightkite is an example of a well written locational application.

  Google had actually written a Latitude application for iPhone, but it was rejected. Apple were concerned that it was too similar to the Maps app shipped with iPhone.

  Google decided to go ahead and rewrite Latitude as a webapp for the iPhone. It was announced late July 2009, and can be accessed from the Google mobile home page or by using the Google Mobile application.

• Google Voice

  The recent controversy with the rejected Google Voice application hangs in the air. This week David Pogue (via Mashable) blogged about Google rewriting their rejected application as a webapp, much the same as Latitude now runs.

  If they get this stood up, this will be the next step in the move from the old school to the new, being VOIP. With Skype possibly on the way out by 2010, Google may fill the void – albeit with many more functions than a simple VOIP application.

  For the time being, there is no iPhone capability for Google Voice.

• Google Docs

  Google docs is currently accessible on the iPhone from Google as a mobile web application.

  The current limitation with the mobile web application is that it is view only, and does not allow sharing of your documents. To perform all the functions you need to use a full browser

• Google Mail

  The iPhone has you covered when it comes to mail. You can either use the built in email application to access Gmail via IMAP, or access the mobile web Gmail. The mobile web Gmail is full featured, and makes use of iPhone/AJAX specific web features to give you an almost dedicated app like experience.

  On the other hand, the benefit of using the built in Mail is offline reading/composing and excellent integration the the iPhone V3 cut/copy/paste features; even for photos and voice memos.

• Google Maps

  Google maps is one of the core applications of the iPhone and iPod line. It comes pre-installed from Apple. The quality of this application has increased with the current V3 firmware providing outstanding features.

• Google Reader

  There is no native application for Google reader. But don’t let this stop you. A couple of avenues are available.

  The mobile web application for reader is as mature as Google’s mobile Gmail. It allows you to perform almost all the features that the full web based reader does, and it makes use of the iPhone safari features.

  If you want something Application based – a new alternative is emerging. The NetNewsWire/FeedDaemon product suite is an RSS reader from NewsGator for the Mac/Windows platforms, respectively. They have a dedicated iPhone application that syncs with the desktop products. NewsGator recently announced that their Beta desktop products now sync with Google Reader, and that an update to their iPhone app is on the way. This solution will allow synchronisation of RSS feeds and unread item status across your Desktop and Google reader, but the dedicated iPhone app is not out yet. You can watch for their iPhone announcement from @newsgator on Twitter, or at their blog.

You can download the Google Mobile application from the iTunes store.

I’ve uploaded the initial public release, v1.2, of my simple Tweet plugin to the WordPress Plugin Repository. You can install the plugin by:

• downloading it from http://wordpress.org/extend/plugins/tweet/ ; or
• On a recent version of wordpress, v2.7 or above, follow these steps:
  1. Login to your wordpress dashboard
  2. Select the Plugins/Add New menu item as shown
     
  3. Search for Author lantrix as shown
     
  4. Click on the Install link for the Tweet plugin

If you need any assistance, you can leave a comment over on the dedicated page for the Tweet WordPress plugin for Twitter.

If you like the plugin, I’m happy to accept donations if that’s your thing.

As of June 26th 2009, the iPhone 3GS was released. Telstra now offer iPhones (the new or old model) on the original plans, but you can now sign up to the Cap plans. Comparing these plans at the $80 per month spend level shows:

Note: For data usage you need to pay an additional cost per month if you don’t want to incur AUD$2 per Megabyte of data. This is the same for iPhone or Cap plan, so I wont compare these in this post.

As can be seen from the above data, the original iPhone plan versus the NextG Cap plans now offered on the iPhone differ significantly. Discounting the flag-fall:

• With the iPhone plan you get 259 minutes of talking time, roughly 4.3 hours.
• With the Cap plan you get 608 minutes of talking time, roughly 10 hours. (Not including the extra $100 credit to Telstra Mobiles).

Hopefully you can see now why the Cap plans are better value. What does one do in this situation? One would think that you could call billing, change plans to a practically exactly the same priced plan – and change over.

With the hope of a changeover, I called billing. I wouldn’t mind taking the hit of having to sign up for 24 months again, and I learned that this would be required – BUT – and there is always a but with Telstra, this wasn’t all. If I wanted to change my iPhone plan to a Cap Plan I would have to agree to the following:

1. Sign up to the Next G cap plan for a full 24 months again
2. Pay out my current plan (in other words pay off the iPhone)

Paying off the current plan would cost me $850 upfront, or $70 per month for the next year.

Telstra – where is the incentive to keep customers. This is not a way to show it. Had you allowed a plan change to one now offered to newcomers to the iPhone on your network, I’d still be a paying customer for another 2 years (an additional year on top of my current obligation). Money grabbing to “pay out” my current plan and THEN signing up to a full new contract is a customer loyalty killer. Next G speed and coverage be damned.

This update is compatible with the iPhone 3.0 Firmware, so many people were hoping that Push notification would be included. It has not been, so the functionality of Skype on the iPhone is limited. Apple does not allow Applications to run in the background, so one can’t receive calls or message notifications in Skype without the app continuously running. The moment you jump out to the iPod, Contacts, Phone or any other part of your iPhone OS, Skype quits.

Without push notifications V1.1 of the Skype App for iPhone remains a novelty for Skype users, and only mildly useful for “away from the desktop” users who need to make a call over wifi.

I used to use Tweetdeck, until Tweetie came out for the Mac (a native client). However on any other non-apple platform I recommend Tweetdeck or DestroyTwitter (both Adobe Air apps) to my friends.

In the last 24 hours Kevin Rose, of Digg fame, blogged about getting hold of the Tweetdeck beta. Since then the blogosphere has gone mad about it. Mashable reports that the app is now live in the Apple appstore.

You can get it for free from the App Store.

This particular H1N1 strain has not circulated previously in humans. The virus is entirely new.
The virus is contagious, spreading easily from one person to another, and from one country to another.
As of today, nearly 30,000 confirmed cases have been reported in 74 countries.
… I have therefore decided to raise the level of influenza pandemic alert from phase 5 to phase 6. The world is now at the start of the 2009 influenza pandemic.
… On present evidence, the overwhelming majority of patients experience mild symptoms and make a rapid and full recovery, often in the absence of any form of medical treatment. Worldwide, the number of deaths is small. Each and every one of these deaths is tragic, and we have to brace ourselves to see more. However, we do not expect to see a sudden and dramatic jump in the number of severe or fatal infections.
… Most cases of severe and fatal infections have been in adults between the ages of 30 and 50 years.
This pattern is significantly different from that seen during epidemics of seasonal influenza, when most deaths occur in frail elderly people. … At the same time, it is important to note that around one third to half of the severe and fatal infections are occurring in previously healthy young and middle-aged people.

This is also a timely reminder to people who work in office spaces about coughing/sneezing not into your hands, but the best cloth at hand. Two years ago at the start of the Flu season in Australia I blogged about the benefits of using your sleeves for catching germs. I’ll re-iterate this again with this comic but well done video:

The WHO has more details on the H1N1 strain of the Flu. There are also details on the current severity of this strain.
