If you are a computer professional looking for a great place to work, you might consider Magenic. We’re looking for good consultants in San Francisco, Minneapolis, Chicago, Atlanta and Boston.

In particular, we’re looking for people with really good .NET development skills, XAML and/or web design skills, SharePoint development skills and SQL Server skills.

http://magenic.submit4jobs.com/

Magenic is a pure Microsoft focused consulting company. As such, you’ll get to work with people who share your technology focus and interests. All we do is .NET or .NET related work like SharePoint and SQL Server. Our clients are in nearly every vertical market, and that means we get to use cool technologies – from ASP.NET MVC and Silverlight to SQL BI tools and BizTalk to TFS and Subversion. Some of our projects involve large, geographically distributed teams. Others have just a few Magenic consultants working with a customer.

Magenic Studios is our UI design group. It is a national group, which means there’s travel, and also means the people in Studios get to work on the coolest UI design projects. The focus of this group is XAML and web design, not development. We hire people who are technology savvy – we’re not looking for Photoshop-only people, but rather our people know html and css and understand how styles cascade and interact. The same on the XAML side – we’re not after C# skills, but our people understand why a StackPanel is preferable to a Canvas, and how to use styles to control the appearance of the UI.

Our consultants are experienced and enthusiastic – which means it is a lot of fun to work with them. Every time I get to interact with a Magenic project team I learn something new, either about .NET itself, or ways in which the technology can be applied to solve complex business problems. And our consultants interact across the company, freely tapping into the shared experiences and knowledge of their colleagues. Magenic has a great culture for passionate technologists!

For my part, I’ve worked for Magenic for nearly 10 years now, and it has been a great experience. I love working with the kind of people Magenic hires. And I love working for a company where the owners and managers put so much energy into making the company a good place to work, while also remaining focused on keeping the company successful, sustainable and vibrant. In these economic times (like those of 2001-2002), maintaining that balance is challenging, so it is nice to be able to have confidence that the company is in good hands.

Of course we all hope the economy continues to improve, and the reality is that, thanks to current economic improvements, Magenic needs more consultants now in all our offices. So if you’ve been a professional technologist for a few years and want to work at a great company with people who share your passion for software, UI design, web work or data – you should really check out Magenic.

There’s a lot of understandable buzz about the iPad, including this well-written post that I think conveys something important.

As a Microsoft-oriented technical evangelist I’m now almost constantly asked what I think of the iPad. I’ve spent perhaps a total of 20 minutes with one, so I’m not an expert, but I can confidently say that I found it very pleasant to use, and I think it is a great v1 product.

(as an aside, many people also call it a “Kindle killer”, which I absolutely think it is NOT. It is too heavy, the screen is shiny and backlit and the battery doesn’t last 1-2 weeks – it was almost inconceivable to me that anything could replace real books (but the Kindle did), and the iPad certainly doesn’t compete with real paper or the Kindle)

I think the iPad reveals something very, very important. As does the iPhone, the Android phones and the upcoming Windows Phone 7: most users don’t need a “computer”.

Not a computer in the traditional sense, the way we as software designer/developers think about it.

Given the following:

  • “Instant” on
  • Primarily touch-based UI for the OS
  • Apps (and OS) that is designed for touch through and through (and no non-touch apps)
  • Light weight
  • Good battery life
  • Good networking (including home LAN, corporate domain, network printing, etc)
  • Portable peripherals, and standard connectors (USB, Firewire, ESATA, etc)
  • Docking station capability

I submit that your typical user doesn’t need a traditional computer. Sure, there are the “knowledge workers” in accounting, who push computers harder than developers do, but they aren’t a typical user either.

From what I can see, a typical user spends a lot of time

  • reading and composing email
  • using specialized line of business apps, mostly doing data entry and data viewing/analysis
  • browsing the web
  • playing lightweight casual games (solitaire, Flash-based games, etc)
  • using consumer apps like birthday card makers
  • organizing and viewing pictures and home videos
  • creating simple art projects with drawing apps, etc

None of these things require anything like the new i7 quad core (w/ hyperthreading – so 8 way) laptop Magenic is rolling out to all its consultants. Most users just don’t need that kind of horsepower, and would gladly trade it to get better battery life and more intuitive apps.

Which (finally) brings me to the real point of this post: today’s apps suck (just ask David Platt).

David talks a lot about why software sucks. But I want to focus on one narrow area: usability, especially in a world where touch is the primary model, and keyboard/mouse is secondary.

I have a Windows 7 tablet, which I like quite a lot. But it is far, far, far less usable than the iPad for most things. Why? It really isn’t because of Windows, which can be configured to be pretty touch-friendly. It is because of the apps.

Outlook, for example, is absolutely horrible. Trying to click on a message in the inbox, or worse, trying to click on something in the ribbon – that’s crazy. I’m a big guy, and I have big fingers. I typically touch the wrong thing more often than the right thing…

Web browsers are also horrible. Their toolbars are too small as well. But web pages are as much to blame – all those text links crammed together in tables and lists – it is nearly impossible to touch the correct link to navigate from page to page. Sure, I can zoom in and out, but that’s just a pain.

The web page thing is one area where the iPad is just as bad as anything else. It isn’t the fault of the devices (Windows or iPad), it is the fault of the web page designers. And it really isn’t their fault either, because their primary audience is keyboard/mouse computer users…

And that’s the challenge we all face. If the traditional computing form factor is at its end, and I suspect it is, then we’re in for an interesting ride over the next 5-7 years. I don’t think there’s been as big a user interaction transition since we moved from green-screen terminals to the Windows GUI keyboard/mouse world.

Moving to a world that is primarily touch is going to affect every app we build in pretty fundamental ways. When click targets need to be 2-4 times bigger than they are today, our beautiful high-resolution screens start to seem terribly cramped. And these battery-conserving end user devices don’t have that high of resolution to start with, so that makes space really cramped.

And that means interaction metaphors must change, and UI layouts need to be more dynamic. That’s the only way to really leverage this limited space and retain usability.

For my part, I think Microsoft is in a great place in this regard. Several years ago they introduced WPF and XAML, which are awesome tools for addressing these UI requirements. More recently they streamlined those concepts by creating Silverlight – lighter weight and more easily deployed, but with the same UI power.

I’d be absolutely shocked if we don’t see some sort of Silverlight-based tablet/slate/pad/whatever device in the relatively near future. And I’d be shocked if we don’t see the iPad rapidly evolve based on user feedback.

I really think we’re entering a period of major transition in terms of what it means to be a “computer user”, and this transition will have a deep impact on how we design and develop software for these computing appliances/devices.

And it all starts with recognizing that the type of UI we’ve been building since the early 1990’s is about to become just as obsolete as the green-screen terminal UIs from the 1980’s.

It took about 5 years for most organizations to transition from green-screen to GUI. I don’t think the iPad alone is enough to start the next transition, but I think it is the pebble that will start the avalanche. Once there are other devices (most notably some Silverlight-based device – in my mind at least), then the real change will start, because line of business apps will shift, as will consumer apps.

I’m looking forward to the next few years – I think it is going to be a wild ride!

CSLA 4 Beta 1 is now available for download. This includes CSLA .NET version 4 for .NET and Silverlight.

Beta 1 is essentially feature complete. It includes some really big (breaking) changes from 3.8.

Here’s a list of highlights, and of course the change log lists essentially all the changes (with the breaking changes highlighted).

The biggest change is the new business, validation and authorization rules system (info here, here and here). While the new rule system requires changes to your existing business, validation and authorization rules code, the new capabilities are pretty amazing and I think you’ll find it is worth the effort to make the changes.

There are many other changes as well, touching almost every aspect of the framework. From new ASP.NET MVC support, to enhanced MVVM support in Silverlight and WPF, to addressing many of the most common requests around the data portal, CSLA 4 should offer benefits to most application scenarios.

This is a beta 1 release, and is the start of the overall beta-to-release process. Based on your feedback using this beta, I expect to do a couple more beta releases over the next few weeks, with a final release in about 6-8 weeks (so around the end of June).

While I’m sure there will be changes based on feedback, the focus during the beta process is on fixing bugs or addressing anything that is clearly broken. I do not anticipate any major feature changes or enhancements during this process – that’s what the past few months of pre-releases were all about.

CSLA 4 does require .NET 4 and (optionally) Silverlight 4. It also requires Visual Studio 2010. If you are using older versions of Visual Studio, .NET or Silverlight then you should continue to use version 3.8.

Please download CSLA 4 Beta 1 and offer bug reports or other feedback using the CSLA forum.

At the Chicago codecamp this past weekend I was sitting next to a younger guy (probably mid-20’s) who was angsting about what to learn and not learn.

“I’ll never learn C#, it is Microsoft only”

“Should I learn Python? I don’t have a use for it, but people talk about it a lot”

And much, much more.

Eventually, for better or worse (and I suspect worse), I suggested that you can’t go wrong. That every programming language has something to teach, as does every platform and every architectural model.

For my part, a few years ago I listed many of the languages I’d learned up to that point – and I don’t regret learning any of them. OK, I also learned RPG and COBOL, and they weren’t fun – but even those languages taught me something about how a language shouldn’t work :)  But I must say that PostScript was a fun language – programming printers is kind of an interesting thing to do for a while.

Platform-wise, I’ve used Apple II, C64, AmigaOS, OpenVMS, PC DOS, Novell, Windows 3.x, Windows NT, and modern Windows, as well as Unix, Linux and a tiny bit of some JCL-oriented mainframe via batch processing.

Every platform has something to teach, just like every programming language.

I also suggested that people who’ve only ever done web development, or only ever done smart-client or terminal-based development – well – they’re crippled. They lack perspective and it almost always limits their career. If you’ve never written a real distributed n-tier app, it is really hard to understand the potential of leveraging the all those resources. If you’ve never written a server-only app (like with a VT100 terminal) it is really hard to understand the simplicity of a completely self-contained app model. If you’ve never written a web app it is really hard to understand the intricacies of managing state in a world where state is so fluid.

Sadly (in my view at least), the angsting 20-something wasn’t interested in hearing that there’s value in learning all these things. Perhaps he was secretly enjoying being paralyzed by the fear that he’d “waste” some time learning something that wasn’t immediately useful. Who knows…

It is true that things aren’t always immediately useful. Most of the classes I took in college weren’t immediately useful. But even something as non-useful as Minnesota history turns out to be useful later in life – it is a lot more fun to travel the state knowing all the interesting things that happened in various places and times. (I pick that topic, because when I took that class I thought it was a total waste of time – I needed credits and it seemed easy enough – but now I’m glad it took it!)

(And some classes were just fun. I took a “Foundations of Math” class – my favorite class ever. We learned how to prove that 1+1=2 – why is that actually how it works? And why x+y=y+x, but x-z<>z-x. Useful? No. Never in my career have I directly used any of that. But fun? Oh yeah! :) )

A colleague of mine, some years ago, was on an ASP classic gig. This was in 2004 or 2005. He was very frustrated to be working on obsolete technology, right as .NET 2.0 was about to come out. His fear was that he’d be left behind as ASP.NET moved forward, and he had 3-4 more months of working on 1997 technologies. My point to him was that even if the technology wasn’t cutting edge, there were things to be learned about the business, the management style and the process being used by the client.

A career isn’t about a given technology, or even a technology wave. It is a long-term 20-30 year endeavor that requires accumulation of knowledge around technology, architecture, software design, best practices, business concepts, management concepts, software process, business process and more.

People who fixate on technology simply can’t go as far in their career as people who also pay attention to the business, management and inter-personal aspects of the world. It is the combination of broad sweeping technical knowledge and business knowledge that really makes a person valuable over the long haul.

“Wasting” 6-8 months on some old technology, or learning a technology that never becomes mainstream (I learned a language called Envelope of all things – and it was in the cool-but-useless category) is not that big a deal. That’s maybe 2% of your career. And if, during that time, you didn’t also learn something interesting about business, management and process – as well as deepening your appreciation for some aspects of technology, then I suggest you just weren’t paying attention…

All that said, spending several years working on obsolete technology really can harm your career – assuming you want to remain a technologist. I’m not saying you should blissfully remain somewhere like that.

But I am suggesting that, as a general rule, spending a few weeks or even months learning and using anything is useful. Nothing is a waste.
