How to get a list of tables is database backup in sql server
I have a list of database backup files and I want to see what tables are
in each without loading them. How can I do this quickly ? I am suspicious
that whoever loaded these files into a database perhaps did not do it
properly. No logs available of when the load took place and what it
brought in or in there were errors.

Akka - during load testing, forkjoinpool.scan at 20% of cpu time
Akka - during load testing, forkjoinpool.scan at 20% of cpu time
We're making some good progress in load testing and scaling an akka
application but we're seeing scala.concurrent.forkjoin.ForkJoinPool.scan()
coming up as the second highest hotspot around 20% of self time in
visualvm. The Self time (CPU) column says only a fraction of that (say
.05%).
I suspect this means blocking or context switching are potentially
problematic but I'm not too sure - can any one give insight? If it's
context switching I'm guessing tuning dispatcher throughput to a higher
number may net us gains, otherwise if it's caused by blocking we'll need
to read through the code some more.
Any insight greatly appreciated.

COPY string value to byte [] in Java
COPY string value to byte [] in Java
I would like to COPY (not convert) the value of a string to a byte. The
string has been created through transformation of a byte value to base 36,
and then saved as a string.
i.e:
//-------------deconstruct -----------------
byte [] a = [B@7bb4568; // actual byte value
String b = a.toString(); // Copy byte value to a string
String[] parts = b.split("@") ; // split string b to @
String part_1 = parts[0]; // string with value [B
String part_2 = parts[1]; // string with value 7bb4568
//-------------reconstruct -----------------
String c
String pre_fix = "[B@"; // first part of the [B@7bb4568 byte value ,
saved as string
c = pre_fix + parts[1]; // join the two parts
So we have the two parts "reunited" and i want this string value to be
SAVED (and NOT to be converted) as a byte value!
Any ideas???
Thanks in advance!

Partialjs - Get model to render in _layout.html
Partialjs - Get model to render in _layout.html
I have a problem when get model in _layout.html
In default.js, I have model like that
exports.install = function(framework) {
framework.route('/', index);
};
function index(){
var model = {menu: {url:'/product',name:'Product'}};
self.view('index', model);
}
in index.html, I can get model.menu
<ul class="menu_index">
<!-- I can see model.menu here -->
<li><a href="{model.menu.url}">{model.menu.name}</a></li>
</ul>
but in _layout.htmt, I can't
<head></head>
<body>
<ul class="menu_layout">
<!-- But I can't see model.menu here -->
<li><a href="{model.menu.url}">{model.menu.name}</a></li>
</ul>
<div>@{body}</div>
</body>
Any suggestion? Thanks

javax.jdo stopped working with App Engine Backend
javax.jdo stopped working with App Engine Backend
I am writing a backend using the google app engine. I have three projects
using this (One of which was a tutorial) and after installing a number of
updates, the
import javax.jdo...
lines started showing error saying that it could not be resolved. I have
tried to google around a bit but haven't had any luck. Is there something
I need to include in the buildpath or some other error? Thanks

Installing Ubuntu on new HDD, replacing it with old HDD running Windows
pMy question is related to: a
href=http://askubuntu.com/questions/301032/direct-install-of-ubuntu-into-new-hddDirect
install of Ubuntu into new HDD/a I have a Laptop with Windows 8. I would
like to replace the HDD with a new one and install Ubuntu on it. My
question is if I late replace the Ubuntu-HDD with the Windows-HDD will
Windows 8 run without Problems? Will intalling Ubuntu change BIOS or
something on the pc that can cause any Problems when I insert the old HDD
with Windows?/p pThanks /p

Proof of $X+\csc{\left(\frac{\pi}{X}\right)}>2\csc{\left(\frac{\pi}{2X}\right)}$
Proof of
$X+\csc{\left(\frac{\pi}{X}\right)}>2\csc{\left(\frac{\pi}{2X}\right)}$
When $X$ is greater than 1, I want to prove that
$X+\csc{\left(\frac{\pi}{X}\right)}>2\csc{\left(\frac{\pi}{2X}\right)}$
where $\csc{(\cdot)}=\frac{1}{\sin{(\cdot)}}$.
Plotting the above expression using computer software, the plot shows the
inequality is true.
How to prove it mathematically?
Thanks in advance.
