Mads Torgersen on C# dynamic: “We owe it to IronPython and Ruby to make them first class languages.”

Mads Torgersen: “Static typers put the ‘anguish in languish’.”

Keith Robertson: “I’m here to sell you something. You can tell because I’m the one with the tie.”

Erik Meijer: “C# dynamic ‘is like the needle exchange program’.”

Tim Macfarlane: “We’re planning on putting [Tycho] on the DLR pretty soon.”

Karl Prosser: “When I see squiggly brackets, it feels like a real language to me.”

Jeffrey Snover on Powershell: “No prayer based parsing.”

Lars Bak: “It’s good to have a slow compiler because that gives you job security.”

Joshua Goodman: “The way PMs fix things is by sending email.”

Erik Meijer: “I love the math – you don’t need brain to do math. It’s all symbol pushing.”

Luke Hoban: “CodeDom is able to handle any language that is C#. Including VB.”

Erik Meijer: "LINQ is the solution to everything.”

Philip Wadler: “Monads aren’t everything!”

Philip Wadler: “Nothing is so practical as a good theory.”

Erik Meijer: “Because of reflection, every language on the CLR is dynamic.”

I’ve enjoyed myself at Lang.NET and found the people and content are brilliant. I’ll definitely be back again next year. Kudos to the guys who helped set these up.

Insert into NewStudy

select studyid,((29 + 1) - 27) * Rand() + 27,null from StudyTable

It will only generate Rand() once and fill in all rows with the same data, which is not what I want.

In order to generate a random number for each row, I have to create a view of the RAND() function:

CREATE VIEW vRandNumber

AS

SELECT RAND() as RandNumber

go

Insert into NewStudy

select studyid,((29 + 1) - 27) * (select RandNumber from vRandNumber) + 27,null 

from StudyTable

This works very well. Of course, 29 and 27 are my min and max respectively. I can create a separate function to do the same thing:

CREATE FUNCTION RandNumber(@Min int, @Max int)

RETURNS float

AS

 BEGIN

 RETURN @Min + (select RandNumber from vRandNumber) * ((@Max+1)-@Min)

 END

So instead, I can do RandNumber(27, 29) within the statement.

The problem why I didn’t use this randomization is because of permissions. Elevating a standard user to allow creation of a view is disallowed in my situation.

So this is what I did instead, to keep within the boundaries of the permissions, is to use row_number() instead. Take the mod of row_number by ((@Max + 1) – @Min) which is 3 for my case and add the @Min to it. It’s not random, but deterministic, but it works well enough for my case.

Insert into NewStudy

select studyid, (row_number() over (order by studyid)) % 3 + 27,null

from StudyTable

So that’s it. A deterministic pseudo “random” (not so random it seems) number based on row_number(). I wonder if there are other solutions to this.

Faulting application name: msiexec.exe, version: 5.0.7000.0, time stamp: 0×49432105
Faulting module name: ntdll.dll, version: 6.1.7000.0, time stamp: 0×49434898
Exception code: 0xc0000005
Fault offset: 0x00000000000ebbaa

Faulting application path: C:\Windows\System32\msiexec.exe
Faulting module path: C:\Windows\SYSTEM32\ntdll.dll

This happens whenever you try to install anything that uses msiexec.exe on Windows 7. The workaround is to do a simple registry edit.

HKLM\Software\Microsoft\SQMClient\Windows\DisabledSessions

Remove all entries except default.

Don’t ask me why that works, but it works. I’m back to installing things. It seems people are having this problem just recently. Hope this helps anyone having this problem.

To get into the market, it first has to be light enough, and a screen wide enough to be comfortable. Together with a “Slate Stand” for desktop usage, this will enhance multi-touch on the desktop itself. We now are seeing laptops so slim (1 inch thick) and so light (2 lbs) with screen sizes of 13.1” or larger, I predict that this will be the critical factors in bringing back the slate tablets.

If somehow, someone is able to integrate a “Slate Stand” as part of the tablet design, that will be awesome.

Imagine a “Slate Stand” being a supporting stand to tilt the tablet in a 20 to 40 degrees angle (adjustable of course) for easy touch screen experience. I’m thinking just a fold under the laptop which can increase and decrease the degree angle as the fold gets closer together. Imagine this: /\ :underneath your laptop, and flattening out: —— :when you don’t need it.

Together with full size keyboard which will “slide in and out” virtually on the screen with a flick of a button (or gesture, or on some text input) and each key is big enough for our fingers, I think we’ve got something pretty good going on here.

Re-engineering applications’ user interactions to make full use of multi-touch, and we have endless possibilities. Hey, that’s what WPF is for. *wink*

Let’s hope to see it out there soon!

For those who doesn’t want to click on that link (like myself when I searching for this post again), here’s the code.

//Don’t dispose the following two objects. Sharepoint will take care of their disposal when page is completely rendered.
SPWeb  webInUserContext = SPContext.Current.Web;
SPSite SiteInUserContext = SPContext.Current.Site;
Guid webGuid = webInUserContext.ID;
Guid siteGuid = SiteInUserContext.ID;

SPSecurity.RunWithElevatedPrivileges(delegate()
                {
                    // get the site in impersonated context
                    using (SPSite site = new SPSite(siteGuid))
                    {

                        // get the web in the impersonated context
                        SPWeb web = site.OpenWeb(webGuid);
                       // Do your work here  

                     web.Dispose();
                    }

               });

There we go. I used this piece of code to access the SPFile of a document within SharePoint. SPFile requires elevated privileges, and can’t be access with just your normal privileges.

My code works now, and I’m happy.

If you notice, the master page file in SharePoint Designer is checked out (from the check symbol at the side). It’s supposed to show me “Check In” and “Undo Check Out” and all that. Where is it?

It is under your “Edit” toolbar, “Check In”.

So when it doesn’t display, you know where to go.

Here’s a good post specifying how to hide your sign in link.

You can play around with Welcome.ascx and come up with your custom style sign in.

I ran a few of the test on our website, and boy are there a few optimizations we could have done, especially for the JavaScript within the pages to improve performance. And also some quirks xhtml and css errors which will just make things nice and more standardised.
