Adventures in home working http://steves.seasidelife.com I'm Steve Richards a strategist and all round tech enthusiast working on enterprise desktop, application delivery and collaboration solutions. I work from home by the coast in the North West of England. All the views expressed in this blog are my own. Sat, 09 Jun 2012 16:18:06 +0000 en-US hourly 1 http://wordpress.org/?v=3.5.1 Taking the iPad to work http://steves.seasidelife.com/2012/06/09/taking-the-ipad-to-work/ http://steves.seasidelife.com/2012/06/09/taking-the-ipad-to-work/#comments Sat, 09 Jun 2012 16:18:06 +0000 Steve Richards http://steves.seasidelife.com/?p=1123 I’m on my third iPad. 

  1. The first one was a WIFI only iPad 1 with 32 GB of memory, it didn’t last long.  I found it distracting rather than productive and whilst I loved using Instapaper on it I found I could do most things with the Kindle.  I found WIFI only a real restriction and 32GB to hard to live with, so I sold it on eBay.
  2. Then after the iPad 2 came out I picked up a refurbished iPad 1 with 64GB and 3G. Much better, I loved the freedom on 3G, but after 6 months I found I was being drawn back into distraction mode.  I wanted to focus on productivity again so I sold it and also sold my Macbook Air (another form better than function device) and lived quite happily with just my Kindle and my Thinkpad X220.  Both perfect form/function compromises.
  3. Now I’ve started to use my wifes iPad 2 during the day while she’s at work and I’m rediscovering just how good it is for reading and I’ve started to read PDF’s as well as Instapaper. My usual Cafe’s have WIFI so it’s fine most of the time.  When I’m reading books, I’m out on the garden, walking or cycling I still use my Kindle, but when it’s with me I prefer the iPad.

So I’ve decided to experiment with using the iPad for writing.  I’ve already got the applications – Writing Kit and Blogsy so all I needed was the keyboard and the ideal model has just been released.  It fits in my tiny bag and seems to work just fine.  I’ve settled on the Logitech Ultrathin Keyboard Cover

So my experiment in productivity continues, my Cafe time will now be spent writing AND reading. 

All that said I’m still writing this on the perfect keyboard of the Thinkpad X220.

Back to the future http://steves.seasidelife.com/2011/08/01/back-to-the-future/ http://steves.seasidelife.com/2011/08/01/back-to-the-future/#comments Mon, 01 Aug 2011 10:58:01 +0000 Steve Richards http://steves.seasidelife.com/2011/08/01/back-to-the-future/ A few years ago when I started working a 4 hour day I was in a global role, working mainly with the US.  That meant I had my mornings free and I established a pattern of spending them walking, cycling and swimming with rest break at Cafe’s spent reading.  I worked great, I gradually worked myself back to a full time role. 

It didn’t take long though for that full time role to take a toll on my health and I was quickly relying on pain killers to get me through the day and I was taking ever more time off.  After about a year thanks to the advise and support of my managers and my occupational therapist I was put back on 4 hour days (actually 5 hour days with an extra rest day) but it hasn’t worked as well.  I’m pretty sure it’s because I’ve been lazy. 

Instead of keeping moving during my morning’s I’ve settled into the habit of sitting and reading and whilst this is low stress, movement seems to be one of the keys to keeping my migraines and body pain down and my infections low.  Every holiday proves this too me and yet I still slip back into bad habits.

Even worse though, over the last 3 months I’ve had a wonderful Macbook Air, so light that I had no trouble taking it with me to the Cafe and so not only did I spend my time sitting, but I spent it sitting and working on my laptop.  It wasn’t long before I was on Sametime and full engaged in work during my mornings.  It was only a small step from there to deciding to stay home some mornings to go on conference calls, or catch up with backlog.  Next I was leaving earlier to head into the office and staying later!

So if I look back over the last 3 months as I slipped into bad habits, I had one good month, 1 month off sick and one month very slowly recovering from my month off sick.  During that last month I’ve been gradually drawn into longer and longer working hours, more time sitting and a lot less time moving. 

This last week’s holiday has allowed me the space to reflect and decide to get back to my previous good habits, basically walking, swimming and cycling while listening to loosely work related podcasts with regular cafe stops for reading on the kindle.  Working in the afternoon and hopefully an evening walk or cycle with the family.  I’m also trying to figure out how to establish a meditation session as well and do a little strength exercise at the excellent Fairhaven Lake Fitness trail.

Migraine Madness http://steves.seasidelife.com/2011/03/15/migraine-madness/ http://steves.seasidelife.com/2011/03/15/migraine-madness/#comments Tue, 15 Mar 2011 19:07:27 +0000 Steve Richards http://steves.seasidelife.com/2011/03/15/migraine-madness/ I’ve suffered from migraines for most of my life, but 8 years ago they got much more frequent, up from 2 a month to 10-15 a month.  There was a clear link between this increase and developing Adult Onset Still Disease and I often discussed this with my GP and Rheumatology specialist but no improvement has been forthcoming despite many attempts at lifestyle change and new treatments.  In desperation my GP finally referred me to a specialist migraine clinic who just prescribed more meds.

So frustrated by what I considered to be a “less than comprehensive” assessment and treatment plan from the specialist I decided to do some more research myself (I’ve read several books over the years that have never had much actionable advice) and I settled on Coping with Headaches and Migraine by Alison Frith.

Imagine my surprise as I read this book, a summary of the best advise from the London Migraine clinic, and what unfolded was an exact description of my plight, what had caused it and a series of clear actionable steps to address it.  Not only was the advice actionable, but it contradicted most of what I thought I had already known and was so clear and simple that I was amazed that in dozens of meetings with doctors almost none of it had been mentioned.

Here’s a summary of the key points with enough context to allow readers to see if the advise is applicable to them and to understand why I was so shocked.

Key points:

  1. People who suffer from chronic pain, like people with Rheumatoid Arthritis, who also suffer from Migraines and take pain killers for their Arthritis will often develop chronic migraines as well.  Often going from 2-3 times a month to 10-15.   That’s exactly my situation, the risk was never mentioned by my GP or Rheumatologist
  2. The worst pain killers for someone to take for Arthritis if they suffer from Migraines are mixed Paracetamol and Codeine, even though they are often the most effective. I was prescribed CoCodamol 30/500’s and had them on repeat prescription.
  3. This problem is well documented in the book “Medication Overuse Headache develops in headache-prone people. People who do not have tension-type headaches or migraine do not tend to develop MOH if they use painkillers for other conditions such as arthritis or back pain. People with these conditions who also have migraine should take particular care”.  So it’s amazing that a phenomenon that’s considered “Overuse” that’s documented throughout my medical history and my repeat prescriptions was never spotted. 
  4. About a year ago I found out about rebound headaches and Codeine I discussed this with my GP and agreed a strategy of reducing the CoCodamol to 3-4 times a week and the rest of the time using either soluble paracetamol and caffeine or Ibuprofen.  
  5. Both my GP and Specialist also prescribed Triptans (not pain killers but brain chemistry modifiers)  I took them for a couple of months but noticed my headaches were just as frequent but now more severe.  Not very good advice
  6. This is why this wasn’t very good advice, (more quotes from the book):
    1. The longer that MOH continues, the more difficult it is to treat, don’t delay seeking help – the specialist just gave me more meds, no exploration of my concerns over rebound headaches
    2. Avoid changing one drug for another. This is just as risky for developing MOH – contradicts completely the advice I was given.  In fact the specialist didn’t even ask me what pain killers I took for Arthritis
    3. If you have MOH, all painkillers and Triptans must be stopped completely – otherwise supportive strategies will not help.  contradicts completely the advice I was given
    4. Clinical studies suggest that oral aspirin (600–900 milligrams [mg]) has the best effectiveness.  For 40 years all of my prescriptions have been for Paracetamol + other stuff, never had aspirin been mentioned
    5. Tips for avoiding caffeine-related headache Minimize caffeine in your diet if you can – never mentioned
    6. Combination drugs with caffeine and Aspirin or Paracetamol can lead to medication over-use more quickly – over 50% of the over the counter remedies now seem to also contain caffeine
  7. Finally the specialist prescribed Topamax a migraine prevention drug also used to treat epilepsy -  after 2 days though it was seriously messing with my brain,  I couldn’t focus, couldn’t recall common words, sense of taste changed and body felt “out of alignment” with my brain, as if my sense of where my body should be and where it actually was was 30 degrees out of sync – so I stopped those very quickly!!

Ok so where am I now:

  1. Stopped the regular CoCodamol for 2 weeks while I was working, but still took other pain killers to keep me going during headaches or joint/muscle pain
  2. After 2 weeks stopped all pain killers, and took a weeks holiday, kept healthy and exercised every day, reduced caffeine.  I had headaches every day and loads of shoulder and arm pain – I’m currently 6 days into this and the headaches are still getting worse

Where do I hope to get to, again quotes from the book:

  1. Limit triptan use for migraine to a maximum of ten days per month. Limit painkillers to a maximum of 15 days per month. Remember that it is the number of days that you treat that is important – not the number of doses in a day. Avoid any drugs containing caffeine, codeine or other combination painkillers – this is going to be quite a challenge as when my Arthritis is bad I depend on pain killers to work and sleep
  2. Naproxen can be used to aid recovery from MOH and replace your usual method of pain control, This non-steroidal anti-inflammatory drug is prescribed in a six-week reducing regimen – should be able to use this in about another 10 days time when I am back at work the the bad days, it works for body and head pain
  3. Clinical studies suggest that oral aspirin (600–900 milligrams [mg]) has the best effectiveness and take it soluble with an anti-sickness medications to help nausea and – importantly – to prevent your gut from shutting down – this is what I hope to use on the 10 days a week when I’m allowed to be in pain
  4. Studies show a relapse rate of up to 40 per cent within five years, so you must be on your guard

In summary “MOH is common in those who seek help for their headaches. It is reported in at least ten per cent of those attending headache centres in Europe and up to 70 per cent in the USA”

Kindle Essentials http://steves.seasidelife.com/2010/12/02/kindle-essentials/ http://steves.seasidelife.com/2010/12/02/kindle-essentials/#comments Thu, 02 Dec 2010 14:00:01 +0000 Steve Richards http://steves.seasidelife.com/2010/12/02/kindle-essentials/ A few tips on how I use my Kindle

image Case

I started out thinking I didn’t need a case for my Kindle, but over the months I realised that this was a mistake:

  1. A case means you worry less
  2. A case makes it easier to hold the Kindle, even though it’s slightly heavier
  3. A case lets you prop up your Kindle on a table for easier – hands free – reading
  4. This is the one I went for

Content

Getting content onto your Kindle is key and there’s no better solution than Calibre:

  1. I have a huge library of eBooks built up over the years in all manner of formats.  Many of these are public domain books from Project Gutenberg, some of them PDF documents and many more are electronic equivalents of the many thousands of paper books that I’ve purchased.  Calibre lets me convert these books to suit whichever eReader I happen to have at the time starting with Sony, then iPad, now Kindle.
  2. Amazon has a good collection of free eBooks, note that if you get them from Amazon then your reading position will sync across your devices (assuming you have Kindle apps on them).  If you load them from Calibre then you only get them on your physical Kindle
  3. Amazon has listed other free book collections
  4. Although I like to read magazines on the iPad, Calibre auto-downloads content off magazine web sites and formats and packages it up for reading on the kindle for free.  The results are generally excellent.  Even better it will email the books direct to the Kindle (I use my gmail account to go this).  I leave Calibre running on my Home Server and so each week the magazines all just arrive on the Kindle like magic.
  5. Instapaper is a web service that allows me to capture web content that I want to read from many sources including Google Reader, Twitter and arbitrary web sites.  Gathering web sites is as simple as clicking a bookmarklet, or using the Firefox addin Send to Instapaper.  The Instapaper web service stores all of the URL’s and then on a daily basis will email a neatly packaged up “book” to your Kindle for offline reading.  It’s not as good as the iPad experience which is fully synchronised with the web service, but it’s still useful.  I’m hoping that when the Kindle Appstore gets going one of the first apps in it will be Instapaper!

 

Getting content to the Kindle

I use several methods:

  1. Calibre will transfer content directly to the Kindle via USB, perfect for bulk loading a large collection of books
  2. I generally use email to get ad-hoc content to timagehe Kindle.  I have a 3G Kindle, but I don’t generally want to use 3G for delivery of content, because then I have to pay for it, so I set my threshold to Zero (see pic) and then everything gets delivered via WIFI at no cost, regardless of which email address it’s sent to.
  3. Every week Calibre sends me a bunch of magazines via email, over WIFI
  4. Every night Instapaper send me a bunch of web pages via email over WIFI.  Although Instapaper says it doesn’t use the free kindle email service, you won’t get charged if you set your “personal document charge limit” as I have it above.
  5. I buy — way too many — books as well via the Kindle store and they all get delivered over WIFI or 3G depending on where I am

Kindle vs. iPad http://steves.seasidelife.com/2010/12/02/kindle-vs-ipad/ http://steves.seasidelife.com/2010/12/02/kindle-vs-ipad/#comments Thu, 02 Dec 2010 13:17:33 +0000 Steve Richards http://steves.seasidelife.com/2010/12/02/kindle-vs-ipad/ image I have a Kindle and an iPad, but its the Kindle that’s had the biggest impact on my life – so what’s so great about the Kindle?

The Kindle is for reading, whilst the iPad is optimised for distraction.  Yes it’s possible to do almost everything the Kindle does on the iPad, but not for long.  My brain has been trained by modern life to look for distractions every 5 minutes and if I’m reading on the iPad then it readily supplies those distractions and it does it incredibly well.

In contrast the kindle does only one thing well, it’s a superb text reading machine, yes it has an experimental browser, can read magazines and PDF’s, even play games, but it does all those things badly and slowly.  It’s sufficiently painful to browse the web on a kindle that I never bother, it’s never a distraction.

Why is this single mindedness an advantage over the iPad – because I want to read.  Reading is a real joy, something that I hardly ever get to do enough of and the Kindle is superb at it:

  1. The screen is fantastic, wonderful contrast in all light conditions including full sun
  2. Very light weight, meaning less stress on arthritic wrists
  3. Very long battery life, meaning I never have to worry
  4. Excellent page turning buttons
  5. Small enough to take almost anywhere
  6. Great Kindle apps on all of my devices, including the Blackberry for those very few times when the Kindle’s too big to take somewhere

I never regret an hour or two spent reading, but I often wonder what I achieved after an hour on the iPad.

What does the iPad do best?  Almost everything, but in my “busy” life the one thing it really does that the blackberry and the laptop struggles with is reading rich documents, magazines, manuals, text books.  Goodreader is a revelation in terms of PDF reading and Instapaper is fantastic for reading web pages that I’ve captured on the PC to read later.

I’m hopeful that there will be a dedicated Instapaper app for the Kindle sometime soon that will auto synch with the web service, but for now when it comes to work reading the iPad is king.

iPad discipline and first thoughts http://steves.seasidelife.com/2010/06/03/ipad-discipline-and-first-thoughts/ http://steves.seasidelife.com/2010/06/03/ipad-discipline-and-first-thoughts/#comments Thu, 03 Jun 2010 17:24:11 +0000 Steve Richards http://steves.seasidelife.com/2010/06/03/ipad-discipline-and-first-thoughts/ This is my first post from the iPad using the word press applications, no wysiwyg formatting unfortunately, so I’m not sure what it will look like. Anyway here goes.

The good

– the hardware is wonderful, an excellent screen, very responsive
Touch, amazing battery life, easy to clean (using a micro fibre cloth) which should have been provided!

– the apps show great promise, although they are almost all at version 1, ie functional but not feature rich. They could all do with a few extra features to iron out their niggles in use.

– the performance is excellent, I’ve not experiences any significant lag so far that wasn’t a network constraint

– PDF reading is excellent, I’m using the paid app – GoodReader – and the scanned magazines and PDF manuals and work documents that I have to read a lot are first rate provided you can manage the small text. Executive book summaries and Gartner reports are even better, as they are not quite a4. I downloaded other PDF readers but none are a patch on GoodReader. However getting a large collection of books onto the iPad proved a bit of a pain, I longed to just copy files over to the file system.

– multiple-media is wonderful, I like to consume video podcasts while cooking, washing up etc and the iPad is perfect for this. I’ve also converted a whole load of tv programmes for when I’m travelling and these are excellent too

– I’m not a huge gamer, but even I’ve been immersed in the few that I downloaded, but that’s one more distration in life that I don’t have time for very often

– the on screen keyboard is excellent for typing. I’m currently using two fingers but it’s quick and easy and responds very naturally, the autocorrect is useful as well

– evernote is an absolute dream on the iPad, better than the pc and having my whole notebook offline with me is a real boon.

– the last pass tabbed browser is a very useful app, i use last pass on the PC so it’s great to have all my passwords with me and the ability to open multiple tabs slightly mitigates the lack of multitasking

The not so good

– Im currently in a GPRS coverage area, my Blackberry and iPad are both on o2, the iPad via my mifi. However it’s very noticeable how much more tolerant the bb is to the slow network working 100% reliably. Whereas the iPad frequently times out for example. This may be an issue that I rarely face, hopefully!

– the screen definitely suffers from reflection, it’s been fairly easy to workaround this so far though. Fortunately I had a loose weave micro fibre cloth with me and this is perfect. It’s possible to clear an active screen as well without any touch event being detected

– the iPad is very very distracting. I have a Sony ebook reader as well, when I use that I read! When I pickup the iPad to read I have a dozen other things to draw my attention away and so I’m going to have to learn to be disciplined all over again. This need for discipline makes me doubly pleased that I didn’t invest in a 3G iPad, the miff was MUCH cheaper and requires that extra step to connect, hopefully that will save me from living on line and allow me to retreat into books and magazines some of the time at least

– spoilt by the Blackberry I’ve grown up with multitasking. It’s a real shock to have to go back to a serial workflow, and especially annoying to have to explicitly open applications and then wait for them to update, which ideally would have happened before I needed them in the background

– not having a filesystem visible to all applications seems a real shame, it would be great to be able to backup at filesystem level and to easily copy files to and from the pc. Every application having it’s own synching support is a real loss

– I wish I never had to use iTunes ever again, unfortunately some synching has to be done via that route and I cringe every time it’s necessary

On my way home from the best iForum so far http://steves.seasidelife.com/2009/06/17/on-my-way-home-from-the-best-iforum-so-far/ http://steves.seasidelife.com/2009/06/17/on-my-way-home-from-the-best-iforum-so-far/#comments Wed, 17 Jun 2009 17:44:12 +0000 Steve Richards http://steves.seasidelife.com/2009/06/17/on-my-way-home-from-the-best-iforum-so-far/ What made it the best? I pretty much ignored the scheduled talks and spent
most of the time in one to one discussions. Some of them scheduled in
advance by our great Citrix and Appsense teams, especially Chris and
Alister. Some of them opportunistic scheduled with twitter followers and
some with staff managing the conference. The relatively low attendance made
discussions at the stands viable this time in a way I’ve not experienced at
many conferences. When I did attend sessions, a couple of times it was the
post session chats that added most value.
 
Prior to this conference I had talked myself out of the value of live
conference attendance, but now with this new strategy I’m back on board. It
takes more prep, but it pays off.

I recommend a big screen in the office http://steves.seasidelife.com/2009/06/12/i-recommend-a-big-screen-in-the-office-2/ http://steves.seasidelife.com/2009/06/12/i-recommend-a-big-screen-in-the-office-2/#comments Fri, 12 Jun 2009 12:33:18 +0000 Steve Richards http://steves.seasidelife.com/2009/06/12/i-recommend-a-big-screen-in-the-office-2/

when I got a big screen for my home office I thought I would make most use
of it sat at my desk, luxuriating in all that screen real estate. Whilst I
do use it that way, what’s made most difference is that I can sit on my
sofa with my laptop and use the big screen for remote attendance of web
conferences, watching conference videos, vidcasts etc.
 
Now with Windows 7 I can put all these various video sources in my Video
Library and they are available in media center, which means I can control
the whole experience using the remote control.
 
While I watch I can be taking notes or following up leads on the laptop.
 
When work ends of course, it’s also great for movies and TV.

Does Corporate Failure = PKM? http://steves.seasidelife.com/2009/05/14/does-corporate-failure-pkm/ http://steves.seasidelife.com/2009/05/14/does-corporate-failure-pkm/#comments Thu, 14 May 2009 11:52:35 +0000 Steve Richards http://steves.seasidelife.com/2009/05/14/does-corporate-failure-pkm/ Steve over on the Reflexions blog try’s to answer the question

Does Corporate Failure = PKM? posed by Nick Milton and I must admit I find myself agreeing with Steve, who has a few points of agreement with Nick.  That is up until the point where Nick is quoted as saying:

If the company is doing Knowledge Management properly, and making communal knowledge transparently available at the point of need, then you would not need PKM.

and Steve responds:

Here’s where I think Nick is spot on

At this point we diverge and here’s why:

  1. The personal knowledge that I need to manage is not and never will be the same as any pool of knowledge held by my company, although there will be overlaps and gaps in both
  2. My personal knowledge spans several different companies, and with 60%+ of the content of my knowledge repository being publicly available information, I don’t want it locked up in some company specific silo
  3. In the last 10 years of working for my current company if I’d put my trust in the companies well funded knowledge management infrastructure, it would now be fragmented across dozens of different systems. Some of these different generations of the enterprise system and some functional or project specific repositories that all existed with sound justification
  4. A significant proportion of my personal knowledge management system is meaningful only to me based on a context that only I understand, with a subtlety that I’ve never seen in the meta-data support of any enterprise KM system
  5. Locating the specific “thing I want” in my personal system relies on many clues that don’t exist in enterprise systems and a narrow search scope “just the stuff I’ve tagged, linked, saved or created or modified”.  I don’t see an easy way to create this search scope in another way
  6. I’ve been an avid contributor to enterprise KM at the same time as I’ve built my personal knowledge, but I’ve contributed a small subset to the enterprise, because much of my personal stuff would be clutter to the enterprise, lacking the connections and context that make it knowledge to me
  7. I’d never consider my personal knowledge as a substitute for enterprise PKM or Google, but I find many people who use google or enterprise search confuse being able to find “something” on any topic, with being able to find the “specific assets” I want in the way that I do in my PKM system
  8. One final point is that some of my best work and best external knowledge has been dropped from issued versions of work at the enterprise level, because it didn’t survive a scope cut or a change in customer requirements or didn’t convince some approver.  I still have that stuff. Unissued stuff still has huge value to me, but would quite rightly confuse the enterprise in a big way

In summary I’m all for enterprise KM, but PKM is a complement to it.  A good KM strategy should see itself in this capacity too.  Take a look at the “my life bits” research to see the direction that PKM is going, taken to this extreme I don’t see anyone suggesting that all “my life bits” belong in the enterprise KM system.  Rather it see’s PKM as an extension of the brain.

PKM is one of the most neglected areas within the enterprise, no surprise that there’s such a rich eco system of tools being created directly targeted at the individual, with many now starting to integrate with the individuals network of contacts, to create a personal knowledge network.

Virtualisation & slow applications http://steves.seasidelife.com/2009/05/14/virtualisation-slow-applications/ http://steves.seasidelife.com/2009/05/14/virtualisation-slow-applications/#comments Thu, 14 May 2009 11:51:54 +0000 Steve Richards http://steves.seasidelife.com/2009/05/14/virtualisation-slow-applications/ Graham writes an interesting post where he compares the impact of slow login and slow applications.  It’s a good analysis and leads Graham to conclude that forced to choose he would go for slow login, because it’s predictable and infrequent and so can be proactively managed (ie do something else why you wait.

I’ve been mulling over the same issue – but without the nice graphics -when it comes to desktop and application virtualization, and I’m very keen to dig a bit deeper into the user experience impact of a collection of new technologies:

  1. Virtualised applications add a small performance overhead
  2. Streaming virtualised applications adds a significant overhead to launch time, especially in a VDI environment where caching is of limited value (although pre-caching in the image would be better)
  3. Virtualization of the applications configuration and the users personalised settings adds a further overhead to launch times
  4. WAN access to data adds a further overhead to application launch times
  5. We’ve yet to quantify for many niche applications whether non-persistent VDI images (where only the roaming profile is persisted at logoff) are going to be slower, maybe because they cache for performance in the local profile and assume that the users local profile is going to be there tomorrow 99% of the time
  6. Sharing server resources across many users, is likely to work out great on average, but I’m not 100% sure that it will be faster for peak CPU periods which often occur at application start-up
  7. Most VDI deployments encourage users to logoff frequently and that’s likely to increase as the logon/logoff cycle is required in order to update the master image, not only does this affect a few of the points above, but it also makes detailed user state preservation very important – ie saving which applications, files, scroll locations, browser tabs, window positions etc the user has open and restoring them when the user logs back in. 
  8. I dread to think how regular logoffs would impact my productivity, right now I logoff once ever couple of weeks, and it takes me at least 20 minutes to close everything down and open everything up again, if I had to do this every day – the least of my worries would be the time it takes for the OS to boot.

So one things for sure, in the new word of desktop, end user experience performance monitoring is going to be pretty important.

The future of search on the web http://steves.seasidelife.com/2009/05/05/the-future-of-search-on-the-web/ http://steves.seasidelife.com/2009/05/05/the-future-of-search-on-the-web/#comments Tue, 05 May 2009 10:19:48 +0000 Steve Richards http://steves.seasidelife.com/2009/05/05/the-future-of-search-on-the-web/ Every year or so I hear Microsoft talking about Internet Search and implying that Google Search is nothing compared to what Microsoft has in store for us.  Unfortunately what seems to be delivered is useful, but incremental.

I heard about Wolfram Alpha today, and it the first time for years that I’ve seen a real revolution in Internet Search, the kind of revolution that depends on the search engine really understanding the information it’s searching and the content of the search query.  It’s not the full vision of the semantic web, but it’s the best demonstration I’ve seen that illustrates the promise of it.

It’s developed by Stephen Wolfram and team, a genius, who’s delivered a series of breakthrough products and insights over the years.

What it doesn’t do is trigger twitter tools, so currently no tweets to say I’ve blogged from my Blackberry.

New bike http://steves.seasidelife.com/2009/05/02/new-bike/ http://steves.seasidelife.com/2009/05/02/new-bike/#comments Sat, 02 May 2009 19:46:03 +0000 Steve Richards http://steves.seasidelife.com/2009/05/02/new-bike/ I gave my old bike to my Mum a few weeks ago as an excuse to by another, as if even more excuse was needed though I had the opportunity to take advantage of the governments cycle to work scheme. Vince seemed to have a few issues getting a non Halfords bike so I took the lazy route and went for a Carrera Subway 8 and I’ve been very happy so far.

What I added:

A rack and rack bag, which I’ve padlocked to the rack so I don’t have the hassle of having to carry it around

A mirror, I don’t know how to ride without one now, I’ve had one for 20 years

Handlebar extenders, never had these before but they really vary the riding position, great

Jennie gave me her handlebar bag, this has been very useful

The bike:

The disk brakes are a revelation,

The 8 speed hub gears cope just fine with all the hills around here, changing is effortless and you can change gear while stationary

Overall the bike seems great, a bit heavy but that’s the price I’m paying for tough and comfy

This blog post is also an excuse to try out posting via email using the WordPress Postie Plugin.

VMware VDI http://steves.seasidelife.com/2009/04/30/vmware-vdi/ http://steves.seasidelife.com/2009/04/30/vmware-vdi/#comments Thu, 30 Apr 2009 17:08:22 +0000 Steve Richards http://steves.seasidelife.com/2009/04/30/vmware-vdi/ I had the chance to spend the morning being briefed by VMware on their current VDI offerings and their longer term roadmap, a lot of it is NDA but it’s useful to take a look at the broad themes and to contrast their approach to that of Citrix and to the issues we are seeing in the enterprise VDI market.

The good

  1. The core hypervisor is clearly very mature and the most widely used for VDI.  However it seemed to me that the opportunities for VMware to further increase desktop density/core was pretty limited now, from now on we really need to rely on Moore’s law.
  2. Memory over commit, this is a nice feature, to decrease memory costs, but my impression is that impact on overall TCO is pretty small
  3. USB, VMware have written their own USB support, the team have tested a very wide range of USB devices, iPhones, iPods, Blackberries, Scanners etc – they all work, even though not many of them have yet made it all the way through the rigorous VMware QA process
  4. Users who install apps, most VMware VDI customers today have a significant number of users who install applications.  The Citrix Provisioning Server model’s not really suitable for this, although there’s some very interesting third party activity around virtualising end user installed applications at the time the user installs them,  this would allow a users installed apps to roam with them from one pooled non-persistent PC to another, and potentially also into XenApp and Physical Desktops.
  5. The Wyse multi media redirection extensions have been licensed to mitigate some of the limitations of RDP

The potential

  1. The cloud – I was most impressed by the mid term potential of the cloud services capabilities.  More specifically the ability to describe the characteristics and SLA requirements for a Virtual desktop workload, and its associated infrastructure servers.  This would in theory allow us to have a general purpose VMware cloud onto which we could deploy virtual desktops as “just another workload” but with the confidence that all of our SLA’s would be met.  In this model as our environments scaled and performance characteristics changed over the years, we would just make metadata changes and the cloud would adapt to the changing workload automatically.

    The current approach is to have a server infrastructure that’s optimised for the virtual desktop workload at the physical level which is fine for now, but not so flexible in the long term. 

  2. vmSafe,  I really like the idea of taking the anti-malware protection out of the VM and running it on the infrastructure.  Not only does this remove the need to keep running VMs up to date with changes to Antimalware signatures etc, but it should also be more efficient and make it much quicker to respond to a critical events.  However it’s only a nice concept right now.

The stuff I’m not so sure about

  1. The protocol – One of my biggest concerns, currently VMware are taking a variety of approaches, using and extending RDP and then also supporting the PC over IP protocol from Teradici both in software and hardware.  My initial impression is that it’s going to be a long time before VMware has a protocol story that’s as flexible and performant as Citrix has with ICA. In our case where we have a very wide variety of use cases to support, Citrix allows us to use one protocol for all of them.
  2. The broker – improved in that it now supports access to anything that supports RDP, including physical blades, terminal servers and distributed PCs – however there’s no ICA support or Wake On Lan support for distributed desktops that makes it only useful in a few scenarios.
  3. Bare Metal (type 1) hypervisor – I like the idea of a client side hypervisor, I can see that within a year we will have PC’s with all the characteristics of thin clients (low power, no moving parts, cheap, secure, stateless etc) but to which we can stream the OS  (we can already “stream” everything else), however these don’t really need a hypervisor – Citrix provisioning server can do this to physical “thin PCs” now and seems a very good solution, even better when it gets integration with Wan Caches. 

    Where I do see client side hypervisors being popular is the employee owned notebook PC, unfortunately the first release of the VMware bare metal hypervisor will only support a singe VM, so it’s not going to be that attractive for employee owned use cases, also its likely to only support a small subset of laptops, most likely also requiring vPro, and these are likely to be too expensive for employee purchase.

  4. Offline VDI – VMware has another (Type 2) client side hypervisor solution, currently available as an experimental release.  This works on the idea of the user having a Physical PC and a VDI PC and then when they need to go on the road they can “check  out” the VDI PC – download it to their Physical PC and then check it back in at some later date.  I’ve always been a bit surprised by this use case, mainly because almost all the VDI deployments I see are for locked down PCs. 

    For a locked down VDI PC – the whole virtual PC image doesn’t flow down to the client, only the users apps, config and personality, and all that needs to flow back up is the users personality.  The config can flow to the client using something like AppSense which can also copy the users personality back to the server as well.  The users apps can flow down to the client device using Application Streaming.  This just leaves the Virtual machine itself, in the locked down use case it’s always the same master image the flows down to the users PC, nothing gets copied back.  So this is really Operating system streaming and caching, similar to virtual app streaming and caching.

    The benefit that VMware has is a solution that works for locked down and non-locked down PCs and its available now.  However the more elegant model is where we dynamically compose the users offline VDI PC from separate OS, App, Config and personality streams and then persist just the Personality back on the server.  Why’s this more elegant?  because it allows us to use the same, apps, config and personality to dynamically compose physical PCs, client and server hosted virtual desktops, and Terminal Server Apps and Desktops.

    Final thought though is that VMware approach will also be easy to extend to user data, sitting in a virtual disk, so whilst I have some concerns over it’s elegance, it’s a pragmatic approach.

  5. Cloning, the new cloning support is a big improvement, but I still feel that cloning at the storage layer is a better idea.  For example the Offline VDI stuff doesn’t currently work with the View Composer cloning technology, however I’m guessing that it would work just fine if the cloning were done by the storage infrastructure.   

    I’m also pretty amazed by products like ILIO from Atlantis that looks to the hypervisor just like storage, but actually does amazing image management behind the scenes. 

  6. Thinstall, I think ThinStall has some great use cases, but the fact that it doesn’t support dynamic caching in the virtual machine makes some use cases problematic, particularly the Offline VDI and OS streaming ones.  Also it seems to me that precaching virtualised apps in the Citrix provisioning server image would probably be faster than thinstall “streaming” from a network file system, but I’ve no lab results to support that view
  7. User personalisation, VMware personalisation ideas are currently focussed on Virtual Machines.  I like the AppSense/Res approach that allows for the users personality to be injected into physical desktops, client and server hosted virtual desktops and terminal servers/XenApp.
  8. Configuration, I’ve not seen anything from VMware around OS/User and App configuration
