Physical Cores vs Virtual Cores in Parallelism
- by Code Curiosity
When it comes to virtualization, I have been deliberating on the relationship between the physical cores and the virtual cores, especially in how it effects applications employing parallelism. For example, in a VM scenario, if there are less physical cores than there are virtual cores, if that's possible, what's the effect or limits placed on the application's parallel processing? I'm asking, because in my environment, it's not disclosed as to what the physical architecture is. Is there still much advantage to parallelizing if the application lives on a dual core VM hosted on a single core physical machine?Read the article

I hate the standard Query window that comes up when you select new query on a data connection in server explorer, I'd much rather have a T-SQL Editor come up. Is this possible? Maybe not replace that functionality but a shortcut key or something that would bring up a T-SQL editor?Read the article

- by Andrew G. Johnson
Long story short is I tried to quickly update a single row in SQL Server using the Management studio and just typed UPDATE table SET column='value' and forgot the WHERE other_column='other_value' portion.

List of SQL Server errors that should be retried?
- by Christopher
Is there a concise list of SQL Server stored procedure errors that make sense to automatically retry? Obviously, retrying a "login failed" error doesn't make sense, but retrying "timeout" does. I'm thinking it might be easier to specify which errors to retry than to specify which errors not to retry. So, besides "timeout" errors, what other errors would be good candidates for automatic retrying? Thanks!Read the article

PC reboots spontaenously: debugging tips [closed]
- by aaron
I swapped my core 2 duo for a quad core recently, and generally things run fine, but every now and then my computer just restarts. I don't even get a blue screen (Vista 32). Core temp isn't a problem. My thinking is that my power supply is inadequate, but I haven't been able to test that (one idea was to under clock the cpu to see if that helped, but going up in speed was the only simple thing to do in the BIOS) Two cases where I semi-consistanly get problems: - Borderlands windowed after some period of time (and some other games, but Borderlands does it pretty regularly) - watching a video (e.g. quicktime/vlc) and having another video running Another thought is non-cpu heat? Maybe the graphics card? Any thoughts on how to track this down appreciated. Thanks!Read the article

How do I tell my boss, that I need endless cpu power to automate my daily job? By the way, what's your setup, now in sep, 2008. How fast disks? How much memory? How many cores? How big screen?

The setup of the build system is also. Is there an another way?) Thanks!Read the article

Why is fulltextsearch for phrase ignored in SQL Server?
- by cpt.oneeye
I am executing the following SQL statement on an indexed SQL Server 2008 R2 database. SELECT * FROM mydatabase WHERE (CONTAINS(ColumnA,'"The Apple is red"')) The problem is that it returns too many entries. It also returns entries where 'ColumnA' contains only one of the words ('Apple' or 'is' or 'red'...) and not only the entries which contains the exact phrase. According to MSDN this should be the way to search for a phrase. Thanks cpt.oneeyeRead the article

SRAM Cell Diagram - Can someone explain this a bit more clearly? ( From COMP1917 @ UNSW: Lecture 2 o
- by Kristina
I've begun watching a series of first year lectures from the University of New South Wales (UNSW) in Australia, and I'm a bit perplexed by the instructors explanation of how an SRAM gate works. I realize this isn't exactly "programming-related" but since it comes from a series of lectures relating to computing and programming, I thought StackOverflow may be able to help (reddit failed me entirely). In this lecture beginning at around 32:12, Richard (the lecturer) tries to explain how a "latch gate" works within SRAM. Although his students seem to keep up, I feel I'm missing something crucial which is preventing the concept from really "clicking" in my brain. For convenience, I've added the image from the video below: Thanks in advance for any help you can provide, but if this question doesn't fit your view of "programming-related" could you please provide an alternate forum for this in a comment when you cast your close vote? Thanks!Read the article
