Snow Leopard and SAMBA for Pangea

Tuesday, November 10th, 2009, 11:03 am MT - posted by Ross Madden

With the release of Snow Leopard (Mac OS X 10.6) there have been reports of slowness, and hanging of the Finder when attempting to access SAMBA (SMB) network shares.  SAMBA network shares are essentially the most popular type of network share in use today, and the primary method of sharing files between Macintosh computers and Windows computers.

Unfortunately for us, Pangea uses SAMBA to share its files.  So, we have been experiencing these symptoms, primarily the hanging of Finder when attempting to browse through sub-directories within your Pangea space.  For the past couple of months since Snow Leopard has been released, I have been patiently monitoring several forum threads for a solution as well as silently hoping that the releases of 10.6.1 and 10.6.2 would address and fix these issues automatically.  This has not happened.

On the other side, these forum threads have provided a solution to this problem which I have implemented on the Pangea server.  This solution was to remove a line in the Pangea SAMBA configuration file that prevented certain files from being created by Apple client computers (those of you connecting to Pangea with your Macintosh computers).  This line is called the ‘veto file’ setting is now turned off and Macintosh computers will start freely placing these strange files onto the Pangea spaces they access.  These files include .DS_Store, .AppleDesktop, .AppleDouble, and .Trashes to name just a few.  These files will not be visible to Macintosh computers, but will start showing up in the file lists for Windows computers.  The important thing is that this has solved the SAMBA access issues with Finder.

So, for the end users who glaze over with the above technical explanation – Snow Leopard can now access Pangea normally, but will be creating strange files and folders (.DS_Store, .AppleDesktop, .AppleDouble, .Trashes, etc.) which will only be viewable by Windows clients on default.

Thank you for your patience with this, and I will remain optimistic that at some point the future I can re-enable the ‘veto file’ line.  Enjoy!

What is Twitter and why should I use it?

Tuesday, October 13th, 2009, 10:48 am MT - posted by Ross Madden

“Twitter is a free social networking and micro-blogging service that enables its users to send and read other users’ updates known as tweets” (http://www.twitter.com).  What the heck does that even mean though?  Twitter has actually been around for several years, but only this past 12 months has it picked up steam and become a household name.  Twitter is a free service that allows users to send out and receive updates from other Twitter users.  These updates are short, pithy, and allow a user to filter though a vast amount of information in a very short period of time.

twitter

In our academic environment Twitter can be very useful in the following ways.  Twitter use can be split into two camps depending on who you are; you may fall into one or the other, or even both.

Twitter Follower
Most of the average Twitter use is simply following and reading posts that are posted by the Twitter users you follow.  Typically, you will have a list of twitter users that you follow and you can at any point check on those entries to read their content.  Since their content is limited (140 characters) you can quickly read and filter though a ton of information.  So, as a Twitter follower, one can be informed of events, special offers, interesting articles, tips and tricks for various services, and up to the minute news.

Twitter Content Provider
As a Content Provider you are responsible for creating content that you post to your followers on Twitter.  In some sense everyone can be a content provider if you use Twitter as a Social Networking tool.  This is accomplished by updating your life to your friends and family that follow you.  Most of Twitter content circulates around posting links and news and the distribution is amplified by “Re-Tweets” (noted by RT or Via).  RTs allow a user to resend a Tweet they received from an account they follow to all of their followers.  Good content is then RTd over and over again reaching more and more Twitter accounts.  RTs are a way for someone to vouch for another Twitter account, much the same way Google Pagerank works when one page “links” to another page.  These RTs usually end in more accounts following the original sender (due to the valuable content they have provided) and in the end allows the Twitter accounts that are sending out valuable content to reach more and more people.  In the end, those with the more valuable content will have the most followers (at least this is how it should be).

Accessing Twitter
The most basic way to access your Twitter account is through the Twitter website at http://www.twitter.com.  However, with the increase in popularity that Twitter has enjoyed recently there has been an incredible surge in the creation of new client software for whatever device you are using.  On my work computer, I have been using Tweetdeck (http://www.tweetdeck.com/beta).  On my smart phone (iPhone) I have been using a free app called Twitterrific (http://iconfactory.com/software/twitterrific).  With this combination I am able to send and receive tweets with ease from wherever I am.   What Twitter clients are you using?

My personal Twitter experience revolves around the Twitter account for BioIT.  BioIT has been using Twitter under both the Follower and Content Provider roles consistently since around late August.  I have refined the accounts I follow through trial and error.  If I follow an account and it then spams out post after post – I usually un-follow them.  I now have a concise group of accounts that are both creating valuable new content as well as RTing with discretion – only valuable and relatively new content should be RTd.  If I see an account send a dozen RTs out in a short period of time, they had better be amazing conent – otherwise it is just annoying.  Twitter has been valuable to me in that I receive all of my IT related news and events quickly (in terms of reading through all new Tweets in the morning), and in real time – since my Twitter clients are alerting me of new tweets every minute or so (that is – if there are new tweets).

The BioIT Twitter account is attentive to content that deals with end user micro-computing, tips and tricks, and information technology.  These topics must also be valuable to someone in our Academic/Research environment.  I also occasionally post about super cool new gadgets or technology that I feel most will appreciate.  My new content comes from the BioIT weblog and BioIT FAQ library.  All in all, I think the BioIT Twitter account would be valuable to anyone from Colorado State University.  Feel free to follow BioIT at http://www.twitter.com/bioit.

Let me know what you think about Twitter.  Enjoy!

Taking it to Netbook City!

Friday, October 2nd, 2009, 1:01 pm MT - posted by Ross Madden

What is a Netbook?

Netbooks are the term applied to ultra portable laptop computers which in turn come with a low price tag; typically, under $400.  The low price means that these devices are comparably underpowered for the operations a more expensive “laptop” or desktop computer could typically handle.  The ultra portable part means that these devices are very small, usually a 10″ screen or even smaller.  Powered by an Intel Atom processor, these low power chips are great for battery life – as some netbook specifications boast 10+ hours of life on a single charge.  These devices are great for Internet, photo and video viewing, social networking, and basic applications.  Just don’t expect to do anything heavy like Photoshop or video editing.

1005ha

I am aware of at least a few of these devices in the building – and anticipate more.  In fact, I just recently picked up an Asus 1005HA model (shown above).  This $300 machine is replacing an aging Apple Powerbook G4 12″.  A netbook was attractive to me because of its ultra-portability, long battery life, and low purchase price.  For my purposes I will be running Windows 7 32bit RC and Ubuntu Linux Netbook Remix.

It took me only a couple of hours to follow these dual booting directions (http://www.bauer-power.net/2009/06/how-to-dual-boot-windows-7-and-ubuntu.html).  I use the Windows 7 side for the majority of my work on this device – Word, Excel, and web browsing.  The Ubuntu side is available so that I can program of course.

The important thing to remember about these little devices is that they are UNDERPOWERED.  Just like any low cost traditional laptop or cheap desktop setup – they are noticably slower when doing anything other than browsing the web and using services or resources that exist on the web.  However, I would say that close to 90% of what I do on computers happens within a web browser.  E-mail, Social Networking, Netflix – these services all exist in the “Cloud” (See the post for ‘What is Cloud Networking‘) – and with more and more services popping up online, netbooks seem like a good and affordable way to access these resources from wherever you are.

What is Cloud Computing?

Wednesday, September 30th, 2009, 4:26 pm MT - posted by Ross Madden

The term ‘Cloud Computing’ has started to emerge with more frequency over the past few years.  It seems that every new service is operating in the “cloud” and we should be embracing it.  So what exactly is the “cloud” and how can we embrace it?

cloud-thumb-434x318

If you have ever seen one of those network diagrams showing computers, workstations, servers and how they connect to each other they always seem to be connected to the Internet which was denoted as a little “cloud” (click here for an example) – this symbolism has evolved the terminology we use today to refer to the Internet and the services it provides.  Services such as Gmail, Flickr, Amazon all exist on the Internet or “cloud”.  We do not physically have these programs installed on our personal computer, but rather use our personal computer to access them.  This “cloud” concept allows us to access resources and services “on demand” rather than physically owning and understanding how they work.

According to Wikipedia “Cloud computing customers do not generally own the physical infrastructure serving as host to the software platform in question. Instead, they avoid capital expenditure by renting usage from a third-party provider. They consume resources as a service and pay only for resources that they use.”  For example, Netflix allows us to watch movies on demand using a monthly subscription plan.  We do not actually own physical copies of the movies we watch – we access these resources when we want them.

As these services become more and more popular, trimmed down and inexpensive hardware used to access these services is also rising in popularity.  The ultra portable and vastly less expensive (compared to a standard laptop) class of computers, termed Netbooks, is one example of hardware designed to work almost exclusively with these cloud services.  Netbooks are designed for accessing web services, and little else due to their underpowered Intel Atom processors.  These weak little machines do great on the Internet, and have incredible battery life, but really chug if you want to do anything require some muscle such as Photoshop or video editing.  Fortunately for us, (at least from my experiences) much of our time spent on a computer doesn’t require anything beyond the strength offered in these little devices.

To add to the list of services we use on the Internet, Microsoft Office 2010 will come with an slimmed down version of the software that will install in the “cloud” to provide Office applications to licensed users regardless of the computer they use.

I hope this little blurb made some sense.  Enjoy!

PDF to Word (.com)

Thursday, August 27th, 2009, 9:27 am MT - posted by Ross Madden

This morning’s Tekzilla Daily Tip was something I get asked about quite a bit.  How can I edit a PDF file?  Chances are you have either lost the original document or this file was e-mailed to you and you need to make changes.  Adobe Acrobat’s Word export mangles the original formatting of the document, and the built in editing is often not enough for larger changes.  In steps pdftoword.com!  This FREE web service allows you to convert your PDF document to a RTF (Rich Text Format) or DOC (MS Word) file.  Check it out!

UPDATE (8/28/2009 8:00 am) – Once you have your Word file edited, you then convert back to PDF using the free PDF add-on for MS Office 2007 or the built in PDF printer for Mac OS X.
