That's is, what program have you done that involved a lot of mathematical computations?

I've been pondering this myself a few days. One of the most interesting I did was for illustrating joint-and-last-survivor life insurance policies, but that's not as complex as it sounds. I've done some goodess-of-fit stuff and some rate-of-flow and rate-of-change things. But nothing that really every made my CPU smoke.

But I'm looking for such a problem for use as an example. I'm currently writing a little bit of T-SQL to calculate bond prices using that to compare agaist a known set of asking prices on bonds look for in-the-money or out-of-the money offerings (and yeah, I'm just sick enough to want to do that with T-SQL.) Its interesting because it be a good test of how many such comparisons one method vs. another can do. At the same time, it's not exactly attractive as Lorzen's butterflies (if you get that pun why are you here? Why aren't figuring out if gravity really is constant or not?)

Ideally, I'd like to find a problem complex enough that a scripting program really lags behind a compiled one, yet one that can be easily understood and yet be practical.

Thoughts?

MARS is definitely a Yukon-only feature (http://www.winnetmag.com/Articles/ArticleID/41393/pg/3/3.html); Async calls and Object Spaces are supported for any data provider that supports them. UDT et. al. are Yukon specific.

We haven't done a security audit of our applications yet, but I can already tell they have holes in them and it's not all the codes fault. I wish there were more IT pros in the world, specifically where I work, so I wouldn't always have to dink with the systems.

Hello,

I´m testing a little bit with the Whidbey preview. First, I must say: "Good job Microsoft !" because the Visual Studio is very stable for an alpha version ! I love the Generics, Anonymous methods, partial classes and all the C# language addons. It´s now possible to have a public get accessor (property) and an internal set accessor, ...

Now my question: I´m playing a little bit with ADO .NET (mdac9). I want to test the MARS feature. I´ve read in an Addison Wesley book (A first look at...) that I must use "use mdac9=true" in the connection string. But I get an error that this keyword is unknown. What is to do to use MARS feature in this preview version ?

The asynchronous calls in ADO .NET works fine with the element "async=true" in the connection string.


As MS products go, MARS is currently only supported by Yukon SQL Server 2005.

Right, you can put it out on a raw format drive, but virtually never seen that done in actual practice. Not sure why.

Actually, the NTFS choice is far better than FAT for a number of reasons, performance being just one of them. There's block size differences and so on. There's lots of optimization tricks you can do with regard to SQL Server and disks, see: [link]http://www.sql-server-performance.com/ac_filegroup_performance.asp[/link]

I think its most accurate to think of WinFS as being an NTFS meta data database and that's about it. It feeds of journaling events and streams. Beyond that, its more details than I want to dive into right now Smiley

Does CVS work from within Visual Studio, integrated as well like SourceSafe?

Unfortunately being in the UK, US products have not gone done in price (I think I have read somewhere PC's can cost $500 less if you buy them in the US rather than the UK. Visual Studio.NET Pro costs £855 ($1,537) in the UK, $989 in the US - why the huge difference (apart from exchange rates)?

The poor US$ helps exports from the US but harms imports to the US from Europe and Japan. US products cost us the same in the UK, but make the US companies more. It's cheaper to fly to America, buy Visual Studio (or a PC), and then fly back.

Is there a Visual Studio just for Web Development (no Win Forms, but supporting both C# and VB.NET)?

Dreamweaver MX costs $370 in the US, £350 ($629) in the UK. So it is a lot cheaper for Web Development.

The closest .NET IDE (only?) to Visual Studio is SharpDevelop. Doesn't have ASP.NET support and so is probably nowhere near Visual Studio in terms of features. Pretty good though considering it is Open Source - also compiles for Mono as well as Microsoft.NET.

It is expensive if you are non-profit, which is why some companies are using languages like Python (which has a basic free IDE). What about the Eclipse IDE as well? Komodo only costs $295. Not for VB.NET or C# but works for Python/Perl/Tcl/PHP/XSLT (Open Source languages). It shows that IDE's can be a lot cheaper.

What profit is made on Visual Studio, is it 80% like it is for Windows/Office? IMHO anything that makes that much profit is overcharged for (I suppose you could argue for value for money).


I don't care if its integrated or not. I'm not that lazy. IJW like its supposed to. <grin />

I can't speak about the UK markets other than suggest maybe it would be cheaper to buy from the US, pay the conversion and have it shipped.

Yes, there is, its free and its called WebMatrix.

I use Komodo alot because VS.NET doesn't debug XSLT very well. I still frequently find myself using TextPad for VB.NET. Having said that, I'm happy to pay the $1500 per year to renew my MSDN subscription, since it makes me very, very product to have all of the tools.

Sorry, folks, I'm in a really sour mood at the moment and I'm taking it out on you. You see, I've been reading posts on Channel9 from people who seem to have gotten some religion about OSS and are bent on a Jihad against anything and everything Microsoft does. From my point of view, they just don't get it. Yes, Microsoft plays rough, but then in our capitalist economy, who doesn't? You really want to see how ugly a monopolist can get? Go learn about people a like Carnigie and Rockfeller and about the building of the Western US. Or about Packer or Studebaker. And why doesn't anybody call Cisco a Monopolist? But no, I guess its just easier to go bash on Microsoft...

What really set me off though today was this consistent line-of-thinking that I see over and over and over again that "Microsoft is bad because they don't support open standards or free software."

Let's count the number of Microsoft employees involved with W3C efforts and compare that to the number of Novel ones, shall me? Where would SOAP, XQUery and many others be without Microsoft's involvement in them? Give credit where credit is due, please.

By the way, here's a free C++ compiler and toolset from Microsoft. Go knock yourself out: http://msdn.microsoft.com/visualc/vctoolkit2003/

And "Microsoft will never have an OSS product." Then what is this all about: http://sourceforge.net/projects/wix

And Gee, you want a great free database? how about this: http://www.microsoft.com/sql/msde/downloads/download.asp

Oh yeah, and don't I recall Microsoft actually investing in a Open Source tool company called ActiveState?

Here's my bottom line: I like OSS. I like what it can do. Stick to explaining its benefits and you'll earn a lot more creditability with me. Stick to bashing MS just for the sake of bashing MS and all you earn is me tunning you and the movement out.

Lets hope Whidbey and Yukon are much higher quality and bug-free than previous versions. Pity Visual Studio is so expensive (unless you get massive discounts if you are non-profit or government [as you are spending taxes for the tools])

Also it would be good if SourceSafe was anywhere near as good as CVS (or Subversion). Why not have CVS/Subversion support in Visual Studio? Probably not as these are widely used by the Open Source community, which Microsoft seems to be against (at least at the OS / Office Suite level - Linux / Open Office)


Sorry, I couldn't stop laughing.

Let's compare: You can get pro, full edition, retail: $500. Now go figure out how much it would cost you to equip yourself with WebSphere. "So expensive" must be relative to what, NotePad?

I can use CVS all day long with Visual Studio if I want too. I doesn't strike me that Microsoft doesn't want us not to use CVS or SubVersion. In fact, it seems rather popular. Yes, they provide Visual SourceSafe. Yes, its a minimalist soultion. Fine, don't use it.

Maybe I listen to the collective too much and just can't see things from the other point of view about OpenOffice. But I don't see Microsoft as being against Open Source as much as they are for their own products. But then, in our capitalist Economy, that exactly what they should be.

I think the fact that Windows has a monopoly seems to help a lot.

Open Source can only get better and is often designed to work cross-platform. Unfortunately no one has the funds to really compete on the same level as Microsoft which has immense profits and a huge bank account with no debt.

IBM and Novell are the only ones that can really compete (perhaps Sun and Redhat stand a small chance)

I wonder what Redhat would do if they had $50bn in the bank? Would they make Linux even better and user friendly, or make their products proprietary and closed source?

For cheap web hosting with moderate traffic LAMP is the best solution (Linux Apache, MySQL, PHP)


I don't believe that being a Monopoly (if it were) helps Microsoft develop better products in the least. In fact, I think it hurts them. When everybody is running your stuff, you can't be as agile was you want. If the "delay" of Whidbey and Yukon have demonstrated anything, its that. A&B/Miller has kind of proven that just because you're virtual monopoly, that doesn't mean you have best product. Smiley

As for what any company would do, they would do what companies are legally obligated to do: maximize shareholder return. As alturistic as supporting open source sounds, in the end, they have no choice, they have to sell something. With Linux, you're paying for the "value they add to it." With Microsoft, you're paying for the "value they add to you."

VB as was based on COM and was just kludged enough that it didn't make sense for it to migrate as was to the CLR. VB as was didn't support the essential "OO" concepts MS feels languages need today.

My guess is, DP, the first month or so with VB.NET will seem really harsh because there's not many good entry points for you. Yes, learning how to write in the same mindset of VB.OLD is possible, but the real benefit of VB.NET is taking full advantage of the framework. Within six months you wonder why you waited so long. Smiley

Again, I don't want to sound like a Homer here, but I really wish the Sells and Gehtland book would have been out when I first wanted to learn VB.NET. Its just about perfect, IHMO. But, since I was was such an early adopter, I had the Hollis/Lohtka book. That was a great book too, but its total irrelevant now.

People round here keep on talking about managed code. But I don't know what it is. Or why it's so important.
My programming experience is limited to VB but since there is vb.net I guess this is applicable to VB.

If you've beenw writin VB, then you've been -- in a sense -- writing managed code the whole time. Managed code is what unmanaged code isn't. In VB6, you rarely had to worry about freeing up any memory or other resources because the "run time" for VB took care of such issues for you. C++ programmers, on the other hand, had to explicitly "manage" the resources they used like sockets, blocks of memory and so on. In a managed code environment like .NET, the run time takes care of all that work for you.

In current usage, "managed code" means programs running in the .NET CLR that are taking advantage of its resource management schema.

That doesn't mean you are totally off the hook for resource management howerver. There's still some best practices you need to engage in when coding. If a class offers a dispose method, you should call it as soon as you are sure you're done with the instance to free up any system resources it may have tied up waiting for the Garbage collector to come along and make rid of them.

Before you start fretting much about all of this, go make friends with FxCop. It will help you avoid the few really dumb things you might do otherwise (at least, it does for me... <grin />)

Here are a few questions I was asked a few months ago, not for my current position however:

1. What is the difference between Authentication and Authorization in Asp.Net.

2. What is the difference between Polymorphism and Inheritance.

3. Explain what connection pooling is in SQL.

4. What is the difference between a Union and Join in SQL.

5. Explain a scenario where you would use ByRef instead of ByVal.

6. What is the difference between .Net Remoting and Web Services, and when would you use one over the other.

7. What would you use in place of a public variable in Asp.Net and explain why.


Those are a few that came to mind. I will edit the post as I think of more.

These are okay screening questions testing to see if a candidate has a minimum level of knowledge to do the job. I try to question at a higher level: do you have the skills and disposition to be effective in the role I want you for.

Some examples:

We have an RS/6000 running DB/2. We need to combine that data with data residing on our SQL Servers. The data is used in a reporting application build on Access 2003. How would you design a system that allowed this to work with minimum execution time?

I'm really looking for two things: what questions do you ask and what does your design look like.

Another one: We need to develop an application that will accept electronic payments from our clients and will post these payments to both our accounting and project management system. You have 30-days and $200,000 to get the system in place. What do you do?

Here I'm more interested in the questions you ask than what you design.

A final one: You have a bug an application you are writing. You've checked the on-line documentation but the suggested fix doesn't help. Your team mates need you to complete this bit of the program within the next 24 hours or the project is in real trouble. What do you do?

If the applicant say "go have a beer and start surfing the help wanted ads" (yes, I did have somebody jokingly answer that), I'm very tempted to tell them right then and there that that's exactly what they should go do. Immediately. Smiley

1. Nothing "sucks" because "of" its licensing model, it sucks because its a bad user experience. None of licensing models (OSS, GPL or Commerical-no-copy) are immune to this.

2. TCO that isn't based on net-present-benefit is fool's benchmark.

3. Designning systems to operate on "fire-and-forget" for the sake of lowest TCO is a practice that must stop. We need to stop thinking of business systems as solid-state black-boxes and start thinking as Ecosystems that need proper management.

We could do a lot worse than borrowing the thinking put forth by Bruce Sterling: "What if 'Green Design' were just good design?"

No really... the fastest browser on the planet... (ducks, grins!)

Seriously though, I'm all for "if it works in lynx, its all you really need." Needless to say, the Flash people hate me.

IE6 is fine for general use. FireFox is a bit buggy LiveHeaders has been a seriously helpful tool.

The life expectancy of the browser -- as we know it today -- is pretty limited anyway IMHO. By 2007, we won't even need to have this discussion, I bet.

Three thoughts on this

1. DevelopMentors Bootcamps. The ones that run 10-12 hours a day. Especially if you get somebody like Fritz Onion. HARDCORE!

2. Nothing teaches you a product like investing your own time in making it do things you want to do. I'm sort of teaching myself InfoPath as an alternative to writing ASP.NET.

3. Writing a book. You know, you may feel so totally at one with something that you say "oh yeah, I could write a book about that." Go ahead. I dare you. I (breaking the rules of protocol and skipping over the single and double dog dares) TRIPLE DOG DARE you to. You'll learn way more than ever wanted to know.
