Observations from my Romp with Ruby

My experience with Ruby on Rails was a positive one, or to quote the Rails site, it was "Web development that doesn't hurt". I am still by NO stretch a ruby or rails expert but I did learn a lot and I was impressed with the abilities in such a relatively young language. I still believe that no language will ever solve all of the worlds programming ills. But they will continue to get to higher and higher levels of abstraction and developer productivity.

Ruby is essentially an object oriented scripting language. Rails is a separate library set that is focused on productivity enhancements and tools to really accellerate web development. Rails uses the Model View Controller pattern for development and a strong implementation of the Domain pattern for data persistence. You could very easily build a fairly complex app all without any knowledge of the database. (Now there are obviously other concerns with that but we won't dig into that in this post.)

CSS and stylesheets can be automatically generated along with full basic UIs with a tool called scaffolding.. (It's not that pretty but gives something upon which to build and actually works great for validating that you have the right model). For many of the common advanced UI actions there are simple sets of commands as well with built in Javascript AJAX - scriptaculous commands for visual effects, drag and drop, dynamic lists and more. Everyone knows you have to have AJAX to be cool now adays.

If you want to poke at Ruby and learn a bit check out RadRails for development (it lacks intillisense type function at the moment which made me sad but everything else you could want works right out of the box) and InstantRails for a working environment. It's a great combo to get you going in just a few short downloads.

Every language will have some weak spots and Ruby is no exception. But it does work hard to answer many of the common problems in today's frameworks. My favorite (have to give a plug for the Engineering side of things) is things like fixtures and test automation built-ins to encourage test driven development. My biggest question is still, how does it scale with very high volumes?

Solaris vs. Linux

As mentioned in my post Sun gets a new spark I recently had the opportunity to visit with some of the folks from SUN and get some visibility into the efforts they have under way. One of the things that this visit caused me to ponder was Solaris 10. When Sun open sourced Solaris I wrote it off as the death throws of a previously strong giant and it made me sad. I originally cut my Unix teeth on Solaris and did a lot of work with it as the stable foundation on which to build open systems. However, as Linux came into its own I have also been one of those folks who has systematically been replacing Solaris in the data center with Linux. For the most part going with the masses to Red Hat but with occasional forays into others as well.

Some developers that I know have stuck with Solaris for their development environments even through the Linux craze due to tools that they liked. Originally I had gone the other way, moving development environments to Linux and deployment environments to Solaris. Solaris in prod for stability and Linux for tools and speed in development.

With the new innovation going into Solaris, things like ZFS, zones and Grid it gives pause. The difficulty now is that everyone and their kid sister has run Linux, known Linux etc. There is a wealth of Linux talent out there and the Solaris admins are much harder to find. Of course Red Hat has been getting more proud of their products and pricing their support accordingly which also adds to the mix. With all of the recent silliness from Microsoft on their FUD around Open Source and indemnity clauses things get even more interesting. (I personally am of the belief that if they thought they could win they would already be in court... but I am sure the FUD is the real goal)

So given your choice... which would you pick?

Pay attention!

A while ago I read a post by Seth Godin on how to be a great audience. I thought it was a great post and provided some very good tips on what to do and how to listen and be (as the post says) a great audience. The context was a presentation to a group of eighth graders and how he could see who would be the good audience and who would not. The students who leaned forward, engaged and asked questions and drew out a better presentation.

Over the following months I have seen this over and over again in meetings. It's amazing the number of people who don't pay attention in a meeting. They drift off to their blackberry (assuming that the network is still working) while someone else is making a point. People bring laptops to meetings and proceed to answer email, read news (and if it's not an RSS feed of my blog that's just rude) or otherwise ignore why they are there in the first place.

Now I will admit that many meetings that get called seem to be meetings for the sake of meetings rather than meetings with a mission. This can be addressed separately. Be direct in meetings and don't be shy about making sure that there is a focused purpose and when that purpose has been achieved... don't feel that the meeting needs to go on just because it has been scheduled for an hour and fifteen minutes of discussion handled it. Give people the gift of time.

So, in your next meeting, make an effort to pay attention. Listen, lean in, ask questions, be a good audience and for goodness sakes PAY ATTENTION!!

Friday Link Day - Microsoft to buy Yahoo!?

News has started to come out that Microsoft is looking to resume talks to buy Yahoo! I think someone has Google envy.

Along the lines of the silicon related post from earlier this week... IBM announced that they have devised a way to create vacuum spaces in chips that will allow them to use less power and run faster. The chips even "assemble themselves" to a certain degree.

Getting tired of the laws of physics holding them back with silicon Intel is working on Laser chips now. NEC is saying that laser chips could power petaflop-class chips. Optical chips may still be a few years away but the idea sure is fun.

SUN gets a new spark

I recently had the opportunity to go out to California and visit SUN. It was just a short period of time but it was an information packed couple days. We discussed topics ranging from Sun GridEngine to strategic direction, from Developer Tools to hardware threading.

I was particularly happy to see that SUN appears to have obtained a dose of humility. Where their previous corporate strategy seemed for a while to be "ABM" (Anything But Microsoft) they are now focusing on understanding their spot in commodity markets and differentiating based on service. The previous approach and Scott McNeely's top 10 lists was certainly entertaining it didn't do much to further the companies goals.

SUN has now taken a page out of the RedHat handbook on making money with Open Source and are trying to make money with service differentiation. I had written off the initiative to Open Source Solaris as the dieing throws of a declining giant. But listening to the vision that they have and what innovation Sun is now building into Solaris 10 with things such as ZFS and Virtualization such as Zones.

Their approaches with Silicon and drive to innovate there was also interesting. They now sell Sun boxes with AMD and Intel processors. Talk about Cats and Dogs living together. We even discussed a current effort sun is working on with Microsoft for a large system provider where they are serving real time video off of Sun hardware running Windows. ... Let that sink in for a minute...

Another interesting point that was brought up was how Moore's Law and fitting more onto the same bit of silicon applies to RISC chips as well as CISC chips. Since RISC is smaller (Reduced Instruction Set) they can then fit more processors on the wafer. So they are legitimately talking 32 and 64 core processors. Talk about the need to thread your application. Initiatives such as Niagara and Victoria Falls also provide low energy approaches.

Just read some of the press of the days for a glimpse of some of what they have been up to.
