Starting a new endeavor

17. October 2008 12:45 by scott in   //  Tags:   //   Comments (4)

I have been piddling around with an idea for the past few weeks along with all my other ideas.  Today I met with one of my old bosses at Florida Tech about the idea. She works in the program development part of the school.  Its almost like the R&D department for events at FIT.  We discussed bringing an idea like TED's to the South-East corner of the states.  TED's is creative commons which allows it to be done anywhere with the name of TED's.  I like this fact because it allows us to have the name behind the same caliber of information given. 

We made a small timeline to shoot for March after or before spring break.  This will give us plenty of time to plan and make ready one of the best conferences for one of the best innovative organizations on this planet. I personally think, if done right this could be turned into something amazing!

For all that don't know what TED is, here is a brief synopsis:

TED - TED stands for Technology, Entertainment, Design. It started out (in 1984) as a conference bringing together people from those three worlds.

TED conferences include about 50 speakers world wide to come and express ideas that they have.  These ideas are here to help the world on a small and large scale.  Most ideas at TED have helped the human race as a whole and have brought together innovators from around the world.  These innovators then speak for no longer than 18 minutes.  They talk on what ever they have focused on in life.  They then could win scholarships to help with their ideas and network with CEO's of companies along with other various people.  This conference is top notch and you have the ability to learn so much in a very small amount of time.  It adds the ability to collaborate with thinkers and doers in the world in which they now communicate with each other.

The conference is what I will try to bring to the South East.  I hope to write more on this later.  I will try to keep my progress updated regularly.

A Revolutionary way to take notes!

14. October 2008 20:55 by Scott in   //  Tags:   //   Comments (14)

For the past few weeks I have been testing out a piece of software for note taking.  I found the software by luck trolling through www.stackoverflow.com.  The software is called Evernote.  It can do almost everything that is need to do when you need to take a quick note.  All the notes live in an online repository.  Without the repository being Google, I worried that the information might not be there forever.  I decided to take a test drive and let me tell you that this thing just kicks ass.  I have it installed both on my phone and several computers where I can access the notes from anywhere.  I fully enjoy this because my last note taking software was the TASKS section from outlook.  Microsoft was doing a better job with them, but Evernotes ability to take notes anywhere is amazing.  To briefly go through what kind of notes it can take:

Desktop

  • It can take anything typed or from a web browser.  The browser part is quite extraordinary because all you have to do is click a button and it adds a note.  You can either highlight text or make the entire web page a note without highlighting and wa-la, you have a web page that you don't have to bookmark for later.  You can just go back to your notes which then unclogs the bookmarks for the real purpose of what bookmarks were made for.

Phone/PDA

  • Voice notes
  • Text note - Typed text
  • Ink Note - If you have a touch screen you can write on the note.
  • Snapshot - You can take a picture of some document or anything.  If you take a picture of the document, EverNote has the ability to capture the text off the document so it can be edited for later.
  • Upload a file - Currently this isn't on the desktop version, but you can upload a file which will be saved both on your dektops and the database.

Coding

  • I specifically use Evernote a lot when have some interesting piece of code that I want to make sure I have at home too.  Instead of emailing it to my self, I now place it in Evernote, tag it as code and then I am off!

For both os's, you can save, delete, tag, print, categorize each and every note.

I wanted to mention one more thing.  This program is FREE!  The service has limits unless you upgrade, but after using it for several weeks, I have yet to reach my limit.

I hope you will give EverNote a try.  It does also have a IPhone version out as well.

Another way of thinking about how to store data inspired by ASP.NET

14. October 2008 10:38 by Scott in   //  Tags: , ,   //   Comments (49)

A while back I witnessed how the profile properties of ASP.NET are stored in the database.  All the properties all stored in one string.  There is then another string that describes the properties and how to view them and pull them from the database.

For example you have this string:
SmtpServer:S:0:18:Port:S:18:2:Password:B:0:48:ApplicationID:S:20:1:EmailUsername:S:21:15:

Then you have another string that looks like this:
pop.abcdefgh.co.uk257abcdefghij-abcd

If you break it down correctly you could get something like this:

  • Property Name : SmtpServer
  • Property Type : string (S) <-- Or this could be the Serialize As Type
  • Property Start Index : 0
  • Property String Length : 18

Now the question that I ask my self is:
Does this actually increase performance of the system?

I would argue yes and no.  Since the system could have an infinite amount of members attached to it and a countless amount of profile properties.  It would need to have something like this to decrease the amount of rows owned by a single user in the profile table. To give an example, I could be one user with 20 propertie.  If the application had over 1,000,000 users, that would be 20,000,000 rows.  That is huge and you must design for scale when it comes to an application that could potentially be used by all the world.

I would argue no to small applications.  If you only ever expect 1,000 users to an application, then why build something this complex other than for the thrill of it. This is especially the case when you don't need to worry about space on the system.  Space is cheap, but time spent coding a solution for this sample could be huge depending on experience.

I personally would build a generic code base for two ideas of this kind.  You could first build the generic code for the example above, but there would be another generic sample to build for. Lets say that you knew you were only going to ever store numbers in your database for each user.  These numbers could be used for ID's of another tables real data.  So I only want to store ID's of a table for each user.

I would store them like:
1:56:34:39:6798:10:39:40

This is because I wouldn't need another cell to split them up with indexes.  I would just split the numbers by the Colon. I would love to hear everyone's thoughts on this and why or why not it is a good choice.  Thanks for the time to read this.

The next 8 years with Technology.

12. October 2008 08:39 by scott in   //  Tags:   //   Comments (13)

Today I watched a Google Talk today about Technology.  The president nominee spoke about ideas on free Internet, Public opinion, technology within bills that get passed in the house and senate, Public knowledge of bills, and more.

I for one am a Republican with many views against democrats and especially left wing democrats, but I do think that Technology can SAVE THE WORLD.  I have not seen my parties stance on technology, but today I saw the democrats stance on technology.  I ask you to also look at this stance.  Republicans have not shown me what they plan on doing with technology, but democrats have.

So for me and the stance on technology, I lean towards the democratic view even though I am a republican.

I hope all of you also review this video and sit down for an hour and take the time out of your day to do so.  This has greatly increased my chances for voting democrat. 

Please understand, that I am not being political, but to show you what I think should be done in the technology market.

A LINQ lesson

2. October 2008 12:18 by Scott in   //  Tags:   //   Comments (47)

I needed to get a query completed like this in LINQ.

Select max(uid) as uid, Serial_Number from Table Group BY Serial_Number
I thought about it for a while but didn't get anywhere.  I kept testing until I asked another person and they came up with:
 
        using (DataContext dc = new DataContext())
        {
            var q = from t in dc.TableTests
                    group t by t.SerialNumber
                        into g
                        select new
                        {
                            SerialNumber = g.Key,
                            uid = (from t2 in g select t2.uid).Max()
                        };
        }
 
This code is very nice and sweet.  It allows you to select the all MAX Rows of a table with a grouped table column. 
Hope you enjoyed this little lesson.  I decided to save this syntact because it is something I will most likely come accross again.

Found Hacker news

1. October 2008 20:13 by Scott in   //  Tags:   //   Comments (1)

I found a website a few days ago that is very credible to things like Digg and technorati.  Its called Hacker news and is offered by YCombinator.com which is a nest for startups. Hacker news is a very narrowed view of haaackers who work all day to hack away at jobs.  The site is pretty simple in its design, but looks extremely valuable to the person looking to use the NITCH developer community.

 It also uses Open ID which is great so I don't have to register and remember yet another password.

Website can be found here.

Thanks for reading.

When is multi-threading not a good idea?

18. September 2008 09:40 by Scott in   //  Tags:   //   Comments (3)
 
I was recently asked when not to use mulit-threading so I gave them the best answer possible.  I think my answer below fits the bill pretty nicely.
  1. On a single processor machine and a desktop application, you use multi threads so you don't freeze the app but for nothing else really.
  2. On a single processor server and a web based app, no need for multi threading because IIS handles most of it.
  3. On a multi processor machine and desktop app, you are suggested to use multi threads and parallel programming. Make as many threads as there are processors.
  4. On a mulit processor server and a web based app, no need again for multi threads because IIS handles it.

In total, if you use multi threads for other than un-freezing desktop apps and any other generic answer, you will make the app slower over time IF you have a single core machine.

Why? Well because of the hardware switches. It takes time for the hardware to switch between threads in total. On a multi core box, go ahead and use 1 thread for each core and you will greatly see a ramp up in speed at the start and over time as the cores heat up.

StyleCop was just released!

12. September 2008 06:55 by Scott in   //  Tags:   //   Comments (69)

For those that don't know. StyleCop was just released!

For those that don't understand what StyleCop is.  It is a tool that formats your code to all standards that makes it readable and nicely organized for human consumption.  It makes you look like a Rock Star (<-- that phrase is so over used).  I have started to use it and I currently have well over 1000 style errors.  I guess I need to adjust to make it work with the standards set out by the coding gods.

I would suggest a download and you look at it.  It should be at least looked at.
