IT security organizations are spending too much on data protection for compliance but not enough on securing key trade secrets, the real crown jewels of corporate data.
I wanted to build a single PC to fit all my needs, but since hardware virtualization support (Vt-d specifically) is a huge problem, I decided to build multiple single-use oriented computers. In this scenario I want these computers to be as minimal as possible.
So the core of my question is:
"Are there significant performance difference between chipsets?"
I'm considering Sandy-Bridge i7 or i5 for my "game console" computer. And since I will use only one graphic card, one or two HDD, 4-8GB RAM and nothing else, I would be fine with a micro-ATX board with a Q67 (or some other low-end chipset).

Oracle's Master Data Management suite has seen remarkable development progress in the past year and a half. Leveraging out-of-the-box integration to applications provided by Application Integration Architecture, the cost, risk and time it takes to implement an MDM solution has been cut in half. Oracle Applications are now 'MDM Aware', Data Quality tools have reached state-of-the-art status, and new hubs are coming on line. In this AppsCast, Pascal Laik, VP MDM Products discusses this progress, what it means for Oracle customers, and where we are going from here.
Possible Duplicates:
i5 vs. i7 processor dev laptop
Developer Notebook i5 or i7
I could not decide on which configuration below gives better performance for developers on a notebook(running VS.NET, SQL Server, no gaming);
(A) i5 540M + SSD (Intel) or (B) i7 720M + 7200 RPM HDD (Western Digital)
Since these two configurations(A, B) costs nearly same $ for me, I would like to buy the fastest one for my job environment.
Please do not comment just buy this or that, if you can give an inference about your choice I would be appreciated.
Thank you,

In my last question i asked how to best send a string from one view controller to another, both which were on a navigation stack:
http://stackoverflow.com/questions/2898860/pass-string-from-tableviewcontroller-to-viewcontroller-in-navigation-stack
However I just realised I can either pass the path to the file in the app's document's folder as the first (the table view) has already accessed the data in the file should I pass viewcontroller the data to the pushed VC?
Ignoring all the characteristics of each languages and focusing SOLELY on speed, which language is better performance-wise?
You'd think this would be a rather simple question to answer, but I haven't found a decent one.
I'm aware that some types of operations may be faster with python, and vice-versa, but I cannot find any detailed information on this. Can anyone shed some light on the performance differences?
I love the new live event in jQuery 1.3. The question I have is the performance of this event. I know the advantages of using live over click/bind('click') but is there a performance hit for using it over click/bind('click')?
If not, why would you ever use click or bind('click')?
My client wants to standardize address information for existing and future addresses collected for their customers, particularly the street suffixes. The application used to enter and collect address information has the street suffix separated from the address field, but it is a textbox instead of a drop down list therefore things are not standardized. I know there are some options out there to standarize data, but they would like a less expensive alternative. Are there any functions in SQL Server that I can use to standardized data?
I want to configure Haproxy for outgoing mail load balancing.
my configuration file /etc/haproxy.cfg is.
global
maxconn 4096 # Total Max Connections. This is dependent on ulimit
daemon
nbproc 4 # Number of processing cores. Dual Dual-core Opteron is 4 cores for example.
defaults
mode tcp
listen smtp_proxy 199.83.95.71:25
mode tcp
option tcplog
balance roundrobin # Load Balancing algorithm
## Define your servers to balance
server r23.lbsmtp.org 74.117.x.x:25 weight 1 maxconn 512 check
server r15.lbsmtp.org 199.71.x.x:25 weight 1 maxconn 512 check
And when i start service haproxy i get this error.
Starting HAproxy: [ALERT] 244/172148 (7354) : cannot bind socket for proxy smtp_proxy. Aborting.
Please tell me where i am doing mistake.help will appreciated.

I have a code that would call $.load() to get an HTML fragment. In the fragment there will be a list of images and a script that would do some calculation based on the list size. The fragment looks like
<div>
<ul>
<li><img .../></li>
<li><img .../></li>
...
</ul>
</div>
<script>
//... script to do calculation on the list width
</script>
Originally, I use css's max-width to ensure that the image would not exceed 180px. But as IE has no max-width, I use the expression hack. However, it seems when the image are first load, the script cannot get a correct width of image list. Seems like the script load earlier than the CSS expression.
If it is a new page, I can certainly call $(window).load() to ensure all the images are loaded. But what can I do in an ajax html fragment request?
I have a data.frame:
df<-data.frame(a=c("x","x","y","y"),b=c(1,2,3,4))

a b
1 x 1
2 x 2
3 y 3
4 y 4
What's the easiest way to print out each pair of values as a list of strings like this:
"x1", "x2", "y1", "y2"
I am implementing a tree Data structure in c# based (largely on Dan Vanderboom's Generic implementation). I am now considering approach on handling a Count property which Dan does not implement.
The obvious and easy way would be to use a recursive call which Traverses the tree happily adding up nodes (or iteratively traversing the tree with a Queue and counting nodes if you prefer). It just seems expensive. (I also may want to lazy load some of my nodes down the road).
I could maintain a count at the root node. All children would traverse up to and/or hold a reference to the root, and update a internally settable count property on changes. This would push the iteration problem to when ever I want to break off a branch or clear all children below a given node. Generally less expensive, and puts the heavy lifting what I think will be less frequently called functions.
Seems a little brute force, and that usually means exception cases I haven't thought of yet, or bugs if you prefer.
Does anyone have an example of an implementation which keeps a count for an Unbalanced and/or non-binary tree structure rather than counting on the fly? Don't worry about the lazy load, or language. I am sure I can adjust the example to fit my specific needs.
EDIT: I am curious about an example, rather than instructions or discussion. I know this is not technically difficult...
Got the 32bit and 64 bit versions of the Intel VTune Performance Analyser. I installed the 64bit version (I think the installed was the "EMT" one) and when I go to create a new project, upon clicking the button to select an executable to profile, no file dialog popup shows.
I got an old laptop and installed the 32bit on to Windows XP and it works fine.
Regarding the 64 bit version, I did try changing the compatability to XP SP3 but it still didnt work.
Does anyone know how to fix this?
I have installed private key (pem encoded) and public key certificate (pem encoded) on amazon load balancer however when i check the ssl with site test tool (http://www.networking4all.com/en/support/tools/site+check/), i get the following error
Error while checking the SSL Certificate!! Unable to get the local
issuer of the certificate. The issuer of a locally looked up
certificate could not be found. Normally this indicates that not all
intermediate certificates are installed on the server.
i converted crt file to pem using these command from this tutorial
openssl x509 -in input.crt -out input.der -outform DER
openssl x509 -in input.der -inform DER -out output.pem -outform PEM
during setting up of amazon load balancer only option i left out was certificate chain (pem encoded) however this was optional. could this be cause of my issue? and if so i how do i create certificate chain? for the last question i have tried googling however i'm getting more confused than before.
please help
many thanks in advance.
UPDATE
@all thanks for the helpful advice. if you make request to verisign they will give you a certificate chain however this chain includes public crt, intermediate crt and root crt. make sure to remove the public crt from your certificate chain (which is the top most certificate) before adding it to your certification chain box of your amazon load balancer.
if you are making https request from an android app then above instruction may not work for older android os such as 2.1 and 2.2. to make it work on older android os [https://knowledge.verisign.com/support/ssl-certificates-support/index?page=content&id=AR657&actp=LIST&viewlocale=en_US]. on this link click on "retail ssl" tab and then click on "secure site" "CA Bundle for Apache Server". copy and past these intermediate certs into certificate chain box. just incase if you have not found it here is the direct link [https://knowledge.verisign.com/support/ssl-certificates-support/index?page=content&id=AR1409]
if you are using geo trust certificates then solution is much the same for android devices however you need to copy and past their intermediate certs for android.

I'm trying to copy a 200GB file from an NFS mount to a local disk. The local disk is an XFS filesystem on a LVM on top of a RAID 5 system (hardware RAID controler).
I'm using rsync to monitor the transfer speed. At the beginning the IO speed is about 200MB/s, stable for the first 18GB. But then the performance drops by a factor of 10-20 and never recovers to the initial rate. Sometimes it reaches about 50-100MB/s but just for a few seconds and then the process seems to hang for a bit.
At the same time all file-stat operations on the target filesystem are blocking for a long time (minutes). Also interrupting the copy process blocks for several minutes, a sub-sequent delete of the partly copied file takes also several minutes.
Any ideas what could be causing this?
I have an application which intensively uses DB (SQL Server).
As it must have high performance I would like to know the fastest way to insert record into DB.Fastest from the standpoint of execution time.
What should I use ?
As I know the fastest way is to create stored procedure and to call it from code (ADO.NET).
Please let me know is there any better way or may be there are is some other practices to increase performance.
My laptop came with a 500 GB hard drive. I use my laptop for storing my digital photographs, and only have about 14 GB of file storage left on the original hard drive. I have a 750 GB external hard drive, but am leery of relying on it for primary storage as I tend to knock things over and it has already crashed once and I lost a lot of the files. I am looking at a 1 TB internal hard drive, but am concerned if storing so much data will affect the computer's performance. Should I also increase RAM from 4 to 8 GB (the limit for my 64-bit, Windows 7, Asus A54C laptop)?
Hello,
we have a new win2008-R2 (2x Xeon X5570, 32GB RAM).
There I have installed the terminal-server roles, thats all OK.
Currently 5 users are working at this server, but all get a very low performance in their remote-desktop session.
Sometime it takes 1-2 seconds till the keyboard-inputs will be performed and shown.
At the clients I run RDP v 6.1
We have also an older TS-server (based on Win2003 with an Opteron-CPU), there are working about 20 users at the same time. There I do not have the troubles with the inputs at the remote-desktop sessions.
Both servers are connected to the same gigabit-switch.
Any ideas what could cause the troubles at the Win2008 R2?
Many thanks in advance.
Regards
Chris
