Ubuntu 10.04,Ruby on Rails Tutorial v3 dependency fix!

August 8, 2010 at 5:27 am (Free Software, General Info, Linux, Opensource, Programming, Ruby, Ruby on Rails, Technology, Ubuntu, Web2.0)

I’ve been following the awesome Rails 3 tutorial by Michael Hartl at http://railstutorial.org/book. I highly recommend anyone wanting to learn Ruby or Rails (even some other languages thrown in as well) to go to this site and you will learn from a thoroughly professional free online gem of a book. I also recommend anyone who can, to purchase the PDF or hardcover that is being offered to show the appreciation for all the hard work put in to this by the author.

Anyway as I was working through Chapter 3 when setting up the initial gem file for bundler to install all the project’s dependencies I kept getting a screen full of errors. After reading the errors I noticed that the gem install was failing while installing the nokogiri package. After Googling as we all do I noticed on the Nokogiri web site that Ubuntu/Debian required two packages to install the nokogiri package. I was hesitant to install them through the normal apt-get packaging tool because I didn’t want the Ruby Version Manager setup to not be able to find the dependencies since the rubies I use through RVM are installed in my /home/me/.rvm directory. Well after installing the two dendencies the classic Debian/Ubuntu way I was pleasantly surprised that all was well and my gem installs were able to finish without a hitch allowing me to continue with the awesome tutorial.

The two packages needed on Ubuntu/Debian can be installed as follows:

sudo apt-get install libxslt-dev libxml2-dev

*the Nokogiri site has details for a fix without running the RVM setup, be careful not to follow as is on the site if you are using the tutorial as directed on the rails tutorial web site.

And as a reminder make sure RVM is setup as Michael instructs in the tutorial.

Just a few words of caution, when following the instructions for the setup at the beginning of the Rails tutorial be very careful to follow them word for word and with this dependency exception on Linux, everything else works as expected.

Microsoft staying relevent

August 5, 2010 at 12:24 pm (.Net, Apple, Free Software, Google, Linux, Mac, Microsoft, Opensource, Personal, Programming, Python, Rant, Ruby, Ruby on Rails, Technology, Web2.0)

Update: As the Ruby Inside blog points out maybe Microsoft thinks they need to revert back to their old ideas

Lately as I’ve been learning Ruby I’ve noticed some frustrating hurdles that are becoming all too familiar.

Now I know  Microsoft has taken steps to embrace the “other” world of web programmers but as I’ll show, I believe the wrong steps.

As the Ruby and Python web frameworks grew and also the community that insisted on developing web applications in a way that kept them in control of the HTML,CSS etc. Microsoft noticed and responded with the ASP.Net MVC releases. Their also were Windows programmers working on Iron Ruby, Iron Python etc.

This strategy while seemingly plugging the whole in the boat in my opinion is only delaying the inevitable shift developers are making to the “dark side”. Whether Microsoft or anyone else wants to admit it the threat from Mac OS X, Linux, Ruby, Python etc has much more in common then is admitted from the Microsoft camp.

For starters as I’ve said in other blog posts, a great deal of the Mac OS X shift by Windows developers and to be fair even Linux developers has more to do with the tools then it does to do with the pretty beach ball spinny thing ( ie. the pretty things). The Linux shift has more to do with instability at times on the Linux platform but that may be worked out if Ubuntu stays focused on the important things.

Not only do I believe Windows could slow the shift by their current developers but they could also possibly gain some of them back. Rather then try to force everything through the .Net filter they need to do the obvious. Give them what they are looking for.

1.How about a native Bash or Zsh environment. Environment being the key word. There are some applications running natively but far from a complete environment. An even so much of this has to be scraped together from evry corner of the web.

Developers now hanging on by a thread to the Windows platform have to jump through all kinds of hoops to use Windows. There is the Cygwin setup that breaks every time Windows upgrades. Although I must say the Cygwin developers have done a good job keeping things in order. I know Microsoft hates to admit it but .Net and C# isn’t for everyone. Stop thinking everyone wants a .Net implementation of every tool or language there is.

2.Embrace what the developers want to use rather then what Microsoft thinks they should use.

This doesn’t mean Microsoft is giving up on what they see as the future of programming. There are plenty of developers that still use those tools and will continue to stay the .Net path.

3.Embrace the commandline, the classic commandline. There are many developers and sysadmins who have tried to wrap their heads around Poweshell. The object oriented shell isn’t what some want to use. Again there are some who think that way but there are also those who wonder what the hell was Microsoft thinking. When the sysadmins and developers were begging for a better commandline story on Windows I’ll be willing to bet Powershell isn’t what they were thinking. The problem with Microsoft and these technologies is that they spend so much money and time on these technologies before the users get to see them that is more or less stuck with where they’ve gone.

If none of this strikes a note with Microsoft people then maybe we need to just admit that there are droves of developers who just need to keep switching.

There are developers that are holding on by a thread, believing that they can possibly stay on Windows but that thread is getting thin. Try setting up a native Django, or Rails development environment on Windows and see how long before your installing Cygwin, creating symlinks and such to make their environment “feel” native.

I would venture to say with all the free and opensource software that already exists having this happen would be more of pulling these tools together then remaking everything from scratch.

This would give Microsoft a much better story in their competition with Google and web applications in general. How much better off would they be covering much broader of a base of developers then they currently do. Who knows Microsoft could even innovate in this space and shock everyone. I know the resources are there but the will is at this time.

How would they like to see all the old school hackers that even work for Microsoft to stop buying Macs and using Macs to program for Microsoft. When the .Net Emacs project starting getting leaked to the world I truly believed that someone at least got part of the problem. But developers don’t want .Net everything. Microsoft could embrace what developers want even more then Apple and in my opinion shift the tide

P.S. Maybe you’ll listen, maybe you won’t, but at least I tried to articulate a few things that would make Windows seem like a platform I could even think of continuing to use.

As always just my two cents.

Ruby !

July 30, 2010 at 8:14 am (Cloud Computing, Computer Science, Free Software, Opensource, Programming, Python, Ruby, Ruby on Rails, Technology, Web2.0) (, , , , , )

Update: I wanted to mention that I have thoroughly overstated the situation as far as Rails apps seemingly being used more by “real sites”. I noticed a Django developer doing some awesome work on some Discovery websites and a few others. I guess it’s just me hoping that it was Python and not me. Well I guess it is me. I ‘ll keep leaning on my noob status until I can hopefully no longer use that crutch. Thanks to Derek the Python/Django guy who made me take a second look.

It amazes me that the most english-like programming language in the world was built by someone who is not a native english speaker. Maybe the simplicity comes from his inability at the time to be overly verbose, using only statements and such that best communicated an idea to someone with a very basic english vocabulary. I think since Matz has become pretty fluent in the english language though.

One other thing I would like to note. I remember a talk that DHH the creator of Rails gave along with Adrian Holavity, one of the Django creators. DHH ekpt saying that he felt some of the architectural decisions behind Django were better suited to we sites where in his mind Rails ‘ architecure was better suited to web apps. At the time I took as a somewhat snide remark, thinking listen to this saying that Django was for building simple web pages and Rails was for building “real” web apps. Well if you take a look on the web now I think the statement rings true, there seems to be many more complicated, detailed Rails apps compared to Django’s hundreds of sites that seem rather simplistic in the app side of the functionality. Just an observation. What do you think?

Web business, Jason Calacanis or Matt Mullenweg!

July 8, 2010 at 1:54 am (Apple, Cloud Computing, Evil, Free Software, nonEvil, Open Web, Opensource, Programming, Rant, Technology, Web2.0)

I  have been watching This Week in Startups quite a bit lately. As much as I like the shows, the guests, and even Jason Calacanis, he can really come off as a pompous jerk. The show I was watching this evening prompted this post when he started the show talking about having a bad day and as he started to reveal his day he started playing with his hair and mentioning that he “drove in with the tops down in the Tesla“. You know the type, the name dropping type of guy that would seem to be insecure, but I think there is more to him then that. I guess I am kind of annoyed with the side of web startups that are all that made the dotcom boom go bust. You know the guys that are constantly trying to figure out how they can squeeze money from the internet backbone as a junky tries to squeeze his fix from the dealer. Now don’t get me wrong there is an aggressive business side to every successful startup, but the web startups that seem to be the biggest booms are the ones that are created by someone that is passionate about solving a problem and in some cases they even start as they are trying to fix their individual problem(DHH Ruby on Rails). If for nothing else but to save some time (Rasmus Lerdof creator of PHP). Well those are they ideas that blowup because of the sincerity and the lack of the marketing, research pompous money grabbers. Then looking at the new startups Jason is working on seems to show that he cares so little about some of the things relating to his startups that his ideas lack focus and clarity. I loved when I found This Week in Startups and truly feel that is Jason’s niche only to find that now it is world domination, not just with startups (what I consider him rightly qualified for) but this week in books, games, iPads, coffee cups etc. Even Facebook came from a place of sincerity and a genuine need, not to mention obviously from the person that wanted to and was able to fill that niche.
As I search for my place in the larger picture of technology and where I feel best suited to venture out on my own. I also realize that just because I come up with an idea it does not mean that I am the right person to solve it. Like Jason’s Mahalo site I believe is way to vague to attract the future that most people would hope for in a solid startup. I know they are getting the traffic and such but I believe when these targets are narrowed down more to a fixed subject with a reason to exist they succeed because the need was waiting to be filled. Stackoverflow besides the fact of having Joel Spolsky and Jeff Atwood already hitting the ground running was able and passionate about solving the problem at hand. There are in my opinion a few ingredients needed for a successful web startup and the idea and implementation are two of those, but you can tell when the passion, sincerity and believability are missing. The startup has to be more than a company wanting to be sold, it must be a company able to sell and not only through the burst of hype that they get in the first year or two but in the years to come which comes from the genuine desire to solve a problem and follow through with it.
I know there are many who will disagree with me but if there are two camps of entrepeneurs on the web, the dotcommers and the hacker types, who would be there regardless of the millions in the bank.
I guess I would consider myself to be on the side of the Matt Mullenwegs (WordPress) of the web, more than the Jason Calacanises. If you want to see the difference watch some of the interviews Jason gives with the likes of a Matt Mullenweg or a David Heinemeier Hansson (Ruby on Rails, 37Signals) and you’ll see the difference when Jason asks these two about why they wouldn’t want to sell their companies and cash out now.
Just my two cents as always. But I still love ya Jason and will continue to watch the webcasts.
