Do you like to program?  I mean really Buy Lumigan Without Prescription, like to program?  Apparently you aren’t in the minority if you said “no” to that question.  I got into an interesting discussion about hiring good programmers last week and the consensus was that the best programmers were the ones with a passion for it.  This isn’t all that revolutionary to those of us who are passionate about it, but perhaps you disagree.  Isn’t programming just about converting needs into code?  It seems as dry as materials engineering on the surface (no offense to materials engineers out there), and yet discussions about languages, algorithms, and design patterns bring about something akin to a holy war.  Somehow I doubt that materials engineers end up flaming each other over the general advantages of various alloys – independent of any specific application!

It’s always been amazing to me how polarizing computer science issues can become.  Though everyone agrees (in a general sense anyway) that the tools and language are dependent on the scenario, once you start talking specifics, no one can agree on anything!  Though this isn’t productive most of the time, it does certainly demonstrate a passion unmatched in many fields.  People who are really into programming get really passionate about every detail.  Conversely, people who tend to code as a job and nothing more don’t care about the details – they are just tools to get the work done.

Why is one programmer “better” than another?  Maybe that’s too strong a way to phrase it.  Why would I be more interested in hiring the passionate developer?  Well, even though I might need to face heated discussions about design and implementation from time to time, I would know that the person was putting a lot into the effort.  Hours spent at home learning new technologies, time spent at work to eek out every bit of performance and efficiency, and the attitude that the final work reflects personally on the code all mean that a passionate developer is more likely to create good code.  On the other hand, I’ve worked with developers who just like to argue because their knowledge base is narrow and they want to keep designs in their comfort zone.  We need to eliminate this too!

Thus, the programmers that I would look for would be passionate about the field, and their passion would lead them to explore new features and tools to provide more options.  A passionate programmer will consider coding more than just a job and will keep up to date as technology changes.  Does this mean that “day job” programmers can’t write great software, or that passionate programmers don’t have a life?  Not at all.  They aren’t mutually exclusive attributes.  Just like any field though, it’s passion that usually leads to the best solutions.

Buy Toprol XL Without Prescription, This is somewhat of a philosophical post, so bear with me here!  I find the application development process itself to be really interesting and so it’s something that I think about at times.  As a person who writes samples, articles, demos, and other content for  products, it’s pretty common for me to actually need to come up with the idea for the software – not just the software itself.  This is backwards from most software development.

Think about it – an enterprise developer creates software that speeds up or reduces errors for the company’s people.  A “dot com” developer creates a site that addresses some need in order to bring in people for advertising, subscriptions, or what have you.  A hobbyist developer creates a solution to a problem that s/he is having – a magazine collector wants a tool to assist with the collection, and a musician might want a tool for keeping track of gigs.  The bottom line is, as the old proverb goes, necessity is the mother of invention.

Not so with people like me!  The necessity in this case is the need to create interest and provide help with a product or technology.  I end up racking my brain for a scenario that is somewhat realistic and demonstrates the necessary attributes of the product.

As an example, let’s say that I need to come up with a sample of the new file drag-and-drop feature in Silverlight 4.  Drag and drop is nothing new, but it’s new to Silverlight.  I could create an almost “Hello World” style of sample that just exposed a panel, and when a file was dropped it would display the filename.  That’s a pretty basic sample, and a pretty common way to demonstrate something – just create something quick and dirty that shows it.  It’s not very compelling though, and in the end it doesn’t create much more benefit that a paragraph or two of SDK documentation would provide.  The key is to demonstrate real benefit.

Part of a sample is showing how the code works, but an arguably bigger part is showing why you would want it to work that way.  A drag-and-drop panel satisfies the former requirement, but not the latter.  A better example would be the classic file uploader applet.  As you drag files, they get added to a queue and then upload in the background.  This is a clear benefit to a form submission method of uploading files.  It makes sense, it’s quickly graspable, and with some tweaking could probably even be adapted for actual use on a web site.

There is a balance though.  A sample shouldn’t have so much going on that the demonstrated technology is lost.  It should be easy to factor out the rest and focus on the feature of interest.  In the file uploader example, the queuing and uploading needs to be in separate classes so the work of accepting a dropped file is obvious, clear, and adaptable for other needs.

A sample, demonstration, or article that includes code that meets these criteria is considered a success by me.  Doing this on a project with multiple samples, and over multiple projects can be quite a challenge.  It’s very rewarding to get it right though.

Diflucan For Sale, At Aeshen, we are often tasked with figuring out how to build up a community around a given product or technology.  This is an important step in assuring success.  Building up a community around something can be the difference between being a blip on the radar and taking the world by storm.  Building up a community isn’t easy though, and it requires careful intervention from a product’s caretakers in order to see it through.

One way to get the ball rolling is to get the word out as early as possible.  This is a great first step to discover the need.  Early blog posts, articles, and references can really make a difference.  Once people are expecting a technology, they start to really think about how it would change things, and there will be a pent-up demand for it to be released as quickly as possible.

Once people are talking about it, it’s important to get them together.  Creating blogs with commenting and hosting chats can gauge interest further, but also enable people to share their thoughts.  At this point, no one can do much more than conjecture, but as more blog posts and other communications emerge, the discussion will become more focused.

Releasing videos of products or interviews with designers/architects can also get people more interested as they are getting a more in-depth look as what they can expect.

When it’s time to release the technology, it’s vital to have as much content available as possible from day one.  Everyone loves to download that new library, but API documentation is only going to take them so far.  Creating samples is really a requirement.  Creating hands-on-lab documents with detailed explanation of steps get people thinking in the right mindset for getting the most out of it.

With all of these people working with samples and labs, having forums is really important.  This is where people can shine by showing off their knowledge to others and learning together.  Give people points for participating, allow discussions to be flagged as good or bad, and use a layout that allows good content to float to the top easily.  All of this gets people talking, learning, and ultimately using the technology.

Finally, a good community must be nurtured.  Make sure that you have official responses from time to time, release additional samples, talk about upcoming versions, allow users to vote on bug fixes and features.  All of this will make the difference between a few people trying something out, and a community of people passionately evangelizing your work with you.

In my last post I talked about how LINQ to SQL greatly simplifies working with database tables in your code.  No longer do you need to sprinkle SQL throughout your code and iterate through results to create business objects.  LINQ handles it all for you so you can concentrate on what to do with those objects.

Buy Prednisolone Without Prescription, What’s amazing is how well LINQ to SQL’s query generator works.  If you have started using LINQ to Objects, you know how great it is to find specific objects in a collection, to sort, and even create secondary objects from data.  All of this is amazing, but extension methods make it fairly easy to understand what’s happening behind the scenes.  When you work with LINQ to SQL, you include the use of a DataContext object.  This is where the magic happens.

A DataContext encompasses details about how the database relates to the business objects.  This is where you declare that a Person object is an instance of a row from the Persons database table, and the object properties relate to columns.  From there, all CRUD operations can be easily generated.

Simple operations are easy enough, but when you start layering on operations like grouping, Take(), and Skip(), the query  generation really shines.  The DataContext creates an expression tree based on your query, and then executes it when used.  This is called deferred execution and is an important distinction.  Merely assigning a query to a variable, like this:

var people = from p in DC.People where FirstName == “John” select p;

does not result in any SQL queries being sent.  It’s not until you work with the collection that data is retrieved.  This makes it possible to reuse a query throughout your code and always have fresh data.  If you want to cache your results, simply call ToList() on the query, and it will execute right there.  Basically, as long as it’s an enumerable it will execute on each enumeration.  Once converted to a list, the results are static.

There are many great resources out there to learn more about LINQ to SQL.  Fire up AdventureWorks, Northwind, or your favorite sample data and start trying it out!

Synthroid For Sale, If you’re still writing SQL queries in code, you are really missing out.  Writing queries by hand is always error-prone and can lead to long debugging sessions.  As a data persistence model, LINQ to SQL is easy to use and really makes a difference in the quality of code that you write.

After using the LINQ Designer, you have a model of your tables in a standard looking Entity Relationship Diagram.  From there though, your code can query your database by simply working with objects.  If you like LINQ to Objects for working with in-memory collections, then you are most of the way there.

The cool thing about it is how the query generator works behind the scenes.  When you create a query using object calls, a T-SQL statement takes form with all of the necessary pieces in place.  It parameterizes, adds sub-queries , inserts ROW_NUMBER syntax , and does all of this without you needing to think about how it fits together on the database side.

What if policy prevents you from sending ad-hoc queries to the database though?  No problem!  LINQ to SQL lets you specify stored procedures to call for all CRUD operations, then stored procedures to call for business-specific needs.  You lose the query generation coolness at that point, but you retain the ability to work with database data as local objects without tedious work to create objects from result sets.

The objects returned from your LINQ operations provide fully-typed access to your data along with nearly effortless updates and inserts to the database.  You can focus on what to do with the objects, such as binding to user interface elements, rather than spending time integrating data access code.  Let your database team create the queries or stored procedures, then assign them to the objects with ease!

In my next post, I’ll talk more about the mechanics of specifying database hints to the LINQ to SQL designer, and how to make effective use of it all from code.

Topamax For Sale, At Aeshen we work on a lot of new technologies.  We’re often on the forefront of products before they are released.  This makes for a fun time getting to explore the new features to learn about how developers can benefit.  A big part of our job is taking these features and making their value propositions really clear.  The thing with developing is that there are an almost infinite number of ways to do anything.  If I read about a feature that allows data querying in a novel way or that adds some new troubleshooting features, I might be excited by the prospect of it.  Almost always though, people are already doing the same thing using other tools or techniques,  Even if this way results in less code or is easier to maintain, it’s not necessarily a slam-dunk in the eyes of all developers.

Everyone has their favorite ways of doing things.  It’s usually based on custom code, specific tools, third –party libraries, and that special extra touch that they bring to the table.  It takes a pretty big benefit to justify the cost of changing,  There’s the time to learn the new technology to the level of the other choices.  There’s the question of updating existing code or not.  There’s the question of licensing, installation, training for support people, and a host of other questions.  It’s no wonder new features and products are rarely embraced by the general community as quickly as I expect them to be!

The final issue, in my mind, is the question of future.  Every new release is a bit of a gamble.  Will it be deprecated by a new version in a few months?  Will it be abandoned between final beta and release  Will a new product supersede it?  Will it fall by the wayside due to a competitive offering?  It’s a big deal to invest in something new when everyone knows how brutal product lifecycles can be.

I can’t ever help out with that side of things, so I dig into the new stuff and create content to show it off in the best light.  If it doesn’t remain relevant, then I usually feel pretty disappointed.  After all, I’m invested in the new technology due to work required to ramp up and “sell” it.  If it doesn’t take off, and I sense apathy from the greater developer community, I feel like maybe my work wasn’t what it needed to be.  In the end though, the community chooses.  I get to play with shiny new things, and hopefully I helped to inform some decisions!
