Hello
How can I measure programicaly (not query the OS, but measure) the size and order of associativity of L1 and L2 caches (data caches)?
Assumtions about system: It has L1 and L2 cache (may be L3 too, may be cache sharing), It may have a hardware prefetch unit (just like P4+), it has a stable clocksource (tickcounter or good HPET for gettimeofday).
There are no assumtions about OS (it can be Linux, Windows, smth non-standart), and we can't use posix queries.
Language is C. And Compiler optimizations may be disabled.

I'm looking to run a second batch command from .bat but after the first command has been done.
REN "myfile.txt" "my_file.txt"
start "title" "path"
Here, I want the rename command to be executed before the process I wanted to start that has been terminated or executed. why it doesn't work in sequence order?
In writing functions my brain always spends a few milliseconds to check which order of parameters would be best for a given function.
should I write:
public Comment AddComment(long userID, string title, string text)
Or probably:
public Comment AddComment(string title, string text, long userID)
Why not:
public Comment AddComment(string title, long userID, string text)
Do you follow any rules when ordering the parameters for your functions?
Which parameter would you place first and which would follow?
When users make credit card transactions on my web app, I'd like to include the transaction fee on the confirmation page before the user makes the order. The thing is, there are different transaction fees for different cards. Is there a way to determine a transaction fee from the card number?
I'm using Rails and ActiveMerchant, but I figure this question was applicable to other languages as well.
I need to write a sql statement to select all users ordered by lastname, firstname. This is the part I know how to do :) What I don't know how to do is to order by non-null values first. Right now I get this:
null, null
null, null
p1Last, p1First
p2Last, p2First
etc
I need to get:
p1Last, p1First
p2Last, p2First
null, null
null, null
Any thoughts?
Probably a trivial question, but in which order does Exception::getTrace return calls? Most recent first or last? I'd like to know before I implement my error handler.

I have attempted to define this element, but XML Spy rejects is with an ambiguous error. All elements in the sequence are optional. The ValueType element can occur before the RawData element and the DefaultData element. All element in the sequence must appear in this order.
How can this element be made conformant? Thanks!
Hello.
Is there recommended orderin which include files should be specified?
For example, the system files, STL, Boost, go before of after local include files?
is there a particular reason to choose one or another?
Thanks
I’ve read that logical operator AND has higher order of precedence than logical operator IN, but that doesn’t make sense since if that was true, then wouldn’t in the following statement the AND condition got evaluated before the IN condition ( thus before IN operator would be able to check whether Released field equals to any of the values specified within parentheses ?
SELECT Song, Released, Rating
FROM Songs
WHERE
Released IN (1967, 1977, 1987)
AND
SongName = ’WTTJ’
thanx
I created a windows explorer toolbar in C#. This toolbar is removed when uninstalling my applicaiton but it's still shown after unregistering (cached in explorer.exe). explorer.exe needs a restart inorder toolbar to dissapear. How can I fix this by C# code?
Is there a way to specify the tab order of the elements within a jQuery Dialog which itself contains an Accordion? The dialog also specifies one button in the buttons options. For accessibility, we need to be able to tab through the accordion panes, the form elements in each accordion, the button in the buttons options, and the close icon of the dialog itself, but tabbing seems to be skipping over the button in the buttons options, and I can't find any resource that has a resolution for this sort of problem.
I know this is a simple question, but I haven't had the chance to test it in any browser other than Firefox.
If I attach multiple event handlers to a single event on a single DOM element, are the event handlers guaranteed to be called in the order they were added? Or should I not rely on this behavior?
Hello
I have the following test-code:
CREATE TABLE #Foo (Foo int)
INSERT INTO #Foo SELECT 4
INSERT INTO #Foo SELECT NULL
INSERT INTO #Foo SELECT 2
INSERT INTO #Foo SELECT 5
INSERT INTO #Foo SELECT 1
SELECT * FROM #Foo
ORDER BY
CASE WHEN Foo IS NULL THEN Foo DESC ELSE Foo END
DROP TABLE #Foo
I'm trying to produce the following output:
1
2
3
4
5
NULL
"If null then put it last"
How is that done using Sql 2005

Not that I would want to use this practically (for many reasons) but out of strict curiousity I would like to know if there is a way to reverse order a string using LINQ and/or LAMBDA expressions in one line of code, without utilising any framework "Reverse" methods.
e.g.
string value = "reverse me";
string reversedValue = (....);
and reversedValue will result in "em esrever"
EDIT
Clearly an impractical problem/solution I know this, so don't worry it's strictly a curiosity question around the LINQ/LAMBDA construct.
I've decided that today - as soon as this question is answered, in fact - I'm going to dive into learning HTML.
But, looking online, I've noticed there are many types: HTML, XHTML, HTML5, and so on.
So, which should I start with? In what order should I learn them?
And, for that first language, where should I learn at?
