Where is Outlook 2010 Export

by ssmith via Blog on 1/31/2011 10:44:39 PM

In an example of extremely intuitive user experience, the latest version of Outlook has moved things around in the interests of ribbonizing everything.  This would be fine if in fact the trendy new ribbon UI was organized in a fashion that was, well, based on logic.  Sadly, at least in the case of Exporting data, this is not the case.  In previous versions of Outlook, one could navigate to File, Import/Export, and lo and behold, the Import and Export options did appear.  Not ...

I can do that by simply randomizing whether any two elements are greater than, less than, or equal to each other: myList.Sort((x, y) => (new Random()).Next(-1, 2)); That generates a random -1, 0 or 1 for every comparison, right? So it will sort the list into random order, right? . . . . . . . There are multiple defects here. First off, clearly this violates all our rules for comparison functions. It does not produce a ...

Reimplementing LINQ to Objects: Part 42 - More optimization

by skeet via Jon Skeet: Coding Blog on 1/31/2011 5:55:12 AM

A few parts ago, I jotted down a few thoughts on optimization. Three more topics on that general theme have occurred to me, one of them prompted by the comments. User-directed optimizations I mentioned last time that for micro-optimization purposes, we could derive a tiny benefit if there were operators which allowed us to turn off potential optimizations - effectively declare in the LINQ query that we believed the input sequence would never be an IList<T> or an ICollection<T>, so ...
