Which is a better bacikup software?

I'm puzzled as to which is a better backup software:
Carbon Copy Cloner or
Super Duper which says it preserves data that would be lost during something called a roll back.
I don't what that means;
I am backing up to a firewire external drive, is that a good choice?
Need advice
Thanks

I read in SuperDuper that it completely erases your drive and makes a duplicate of the HD. There are documents that I remove from my HD but would like to keep on the backup disc just in case. I may need them in the future. According to SuperDuper they would be erased because they no longer reside on the main HD. I'm looking to update new and changed items but not delete items that no longer reside on the main HD, am I making myself clear?
Yes, the free version of SuperDuper! will always erase the target drive and clone the entire source disk again. The paid version will do what you want. What I have in quotes below is directly from the registered version's menus.
1) Smart Update. "Smart Update will copy and erase what's needed to make the target drive identical to your selections from the source. The result will mimic "Erase, then copy", but will typically take a fraction of the time."
2) Copy newer files. "Any selected files already on the target drive that are older than the equivalent file on the source will be replaced. New files will also be copied; no files will be removed."
3) Copy different files. "Any selected files already on the target drive that are different (in date, size or attributes), than the same file on the source will be replaced. New files will also be copied; no files will be removed."

Which language is better to develop the software that controls the Tektronix-Sony 370A Curve tracer and how to approach it?

Which language is better to develop the software that controls the Tektronix-Sony 370A Curve tracer and how to approach it. I a a fresher in this field. Please any one help us developing the software.

If you're looking to develop a driver for the instrument, one already exists and can be download here or you can get it off of the driver disk that comes with LabVIEW. If you're asking for the best language in which to write an application program that uses the driver, the obviously the answer is going to be LabVIEW. Note that you might get a different answer if you post the question to a Visual Basic or C++ forum but those answers would be wrong.

Which solution is better for schedules task? Console application or windows service?

I have a "MULTI-LEVEL" XML file that I will be getting on daily basis and I want to accomplish following tasks:
1) I have to read and parse the "MULTI-LEVEL" XML data
2) Then I have to set or create some kind of .net service (c#) that read the xml and parse the data once a day (daily)?
3) Now I have SOAP service from other software where I want to feed this XML data to. The schedules service will compare the XML data with software data and update (or add) based on the comparision.
For this task, I come to conclusion that there are 2 best ways to do this:
1) Create a console application and use windows task scheduler to run it everyday
2) Create a windows service that runs in the background
Which is a better way (or reliable) solution to do this task? Please advise

There are several things to keep in mind when writing an app that is designed to run without a user logged in. One of the most common mistakes is requiring some sort of user input. Since the task will run without user intervention you don't want
any sort of calls to Console.ReadLine, MessageBox.Show, etc. They will cause the task to freeze and eventually need to be terminated. You also don't want to rely on any sort of desktop apps running since a user may or may not be logged on at the
time.
Also be aware that a task can be scheduled to run under any user context. As such you either need to ensure it runs under an account with sufficient privileges or that your app needs no special privileges. You mentioned you tried to run it from
bin\debug but you most likely have your project under your Documents directory. Only you would have permissions to that folder and therefore will run into issues if the task is run under a different context. You also mentioned you put it in the
C:\ but users don't have write privileges to that folder and therefore if you tried to write a file out it would fail. If you need to read/write files then you should pick a common location that all users have access to or at least the one that will run the
scheduled task. Be aware that, by default, Task Scheduler will not run a task elevated. You need to check the option to run elevated when you configure the user to run the task under.
One of the key things to ensure you do with a task is verify it is working properly as a normal app. You should also ensure that you have good logging so that if it does fail you can trace down the failure more easily. One common thing that people
tend to do in console apps is put a try-catch around the main function and display a message if an unhandled exception occurs. This is going to cause problems in a task. Simply log the exception and rethrow it so Task Scheduler will flag the run as a
failure.
If you still cannot figure out why your task is failing then please add some logging and then tell us what code is being run at the time and what the failure is.

Which one is better null == object or object == null

I am just surffing on a google and i found one new thing which is new concept to me, but that concept is not cleared
Concept is, i found one place a class object is compaired with the null in following way
if( null == object)
Usually i used
if(object == null)
Problem :- What is the diffrance between these two condition and which one is better?

So... Just use the first way (by default) because that's how people are it reading accustomed to.Agreed. Just to point out, the reason commonly given for preferring (null == object) is that it prevents semantic errors such as (object = null), which is only a problem in Java in a minuscule number of cases.And the practice started in C (or maybe even an earlier language) where it's an issue in many cases. For example,
int i = 0;
if (i = 1) { ... }The "if" line is illegal in Java, but it's legal in C. If the programmer forgets the second = sign, then you get the above. Variable i gets a value of 1, and the expression i = 1 has a value of 1, which corresponds to true (whereas in Java, you can't use an int where a boolean is expected). So the if comes out true, when it should have been false (had we properly used if (i == 1)), and in addition, the value of i has changed when we didn't want it to.
In Java, this would be a compile-time error, whereas in C, it's a runtime error. Compile-time errors are easier to fix, and they don't get the opportunity to cause a problem after the software has been released.
In C, to turn this back into a compile time error, you could get in the habit of writing if (1 == i) Then if you forget the second = sign, you get if (1 = i) which is a compile-time error.
Because Java doesn't equate numerical zero with false and non-zero with true, this issue is, as yawmark demonstrates, much less of a problem in Java.

Which would sound better????

I was going to transfer my PCI Creative Labs Sound Blaster Live 5.1 card to my new PC which will be running on a MSI K4M4-V mboard.
Should I transfer the card or will the onboard sound off the mboard, ie VIA1617A Codec 5.1 Channel AC'97 software audio, sound better???
Thanks
Richard

I agree with osnavi. I had a sound blaster audigy in my computer when I first built it. Thought everything sounded great. Then I had some hardware conflicts and the sound card was to blame, so I removed it for troubleshooting purposes and forgot to put it back in. I started playing one of my games and I was astonished... The onboard was actually able to produce lower bass and in general sounded clearer.
As you have a different board than I do try both. Get a song that has extremes in both high and low sound and see which you like better. One thing as both ironcatt and kafkacell mentioned is in using the onboard sound, the CPU is used more, but with a seperate sound card some pressure is taken off of the CPU because the card is able to handle it. Performance in games is where you will notice most of the difference. But I have never even thought about going back to that card (although I am eyeing the new X-Fi cards).
Good Luck

I am going to buy a macbook pro for grade 12, and I need to know wheather I should get a macbook pro or a macbook pro retina. If someone could tell me (in a very simple way) which one is,better for me and why, I would be ever so apprreciative.

Why do you need a expensive MacBook Pro?
Your attending high school and unless everyone else is rich also your likely going to be a target by the more poorer students for theft or damage to the machine.
You could keep it home, but if you need it for class then your exposed again.
Also at that age your not very careful yet, a MacBook Pro is a expensive and easily damaged machine.
Unless your made of money and so are others at your school, I would recommned a low profile, just does the job cheap Windows PC.
If it dies, gets lost, stolen or damaged because of your inexperince handling senstivie electronics then it's no big deal.
You can buy a Mac later on when your sure you have a need for it, currently there isn't much advantage of owning a Mac compared to a PC, they do just about the same things now, one just looks prettier than the other.
Since 95% of the world uses Windows PC's your going to have to install Windows on the Mac in order to keep your skills up there or be unemployed, so it's a extra headache and expense.
good luck

I use Firefox when a site doesn't work well with Safari. Some people like Google's Chrome, but I find it too instrusive and do not trust Google's security. You can download Firefox from firefox.com.

Which solution for better perfomance?

I'm writing java application based on XML. This application have to store very large XML file into DB (XML file is about 1000MB large). My solution is to divide it into smaller (100MB) parts (because of memory resources) and store it in DB. I have one XMLType table based on object-relational storage (so at the end there will be 10 rows each of 100MB size).
XML file looks like:
<students>
<student id="1">
...// 5 nested elements or collections of elements
</student>
<student id="2">
</student>
<student id="3">
</student>
</students>
</students>
Now I need to get java object Student which correponds to <student>element. My solution is to select whole <student> element and use JAXB to convert it to Java object. While solving a problem with selecting <student> element (just in case you know a solution for my another problem: How to select specific element from a XML document using JDBC? another question raised in my mind.
Which solution has better performance when I don't need to select relational data but I'm interested in xml fragment?
1) Use object-relational storage
2) Use CLOB storage
As I figured out object-relational storage is better for selecting data like student name. But is it also better when I need whole xml fragment?
Isn't my solution completely wrong? I'm quite a newbie in XML DB so it's possible that I missed better solution.
Thanks for any advice

I don't know which version you have regarding 11g, but probably in this case I would go for a table with a XMLType Binary XML column. To make xpath and other statements perform use Structured or Unstructured XMLIndexes to support your queries. The following has worked for far smaller XML documents but the millions we used were good for a total of >> 1 TB total storage size...

Which cover is better whether smart cover or smart case

which cover is better whether smart cover or smart case

It is really a choice to personal preference.
The Smart Cover provides some protection for the front of the device but no side/back protected. However, the Smart Cover is much more easier to use in my opinion and makes the device feel better.
The Smart Case provides all around protection for your iPad and is worth getting. It is not as tough as some of the crazy cases out their that like protect from 100ft drops lol.
So, just go to the Apple store and talk to a representative and he/she will help you out!

Which is a better performer, the macbook air or the mac mini?

Which one performs better, the late 2013 macbook air (standard configuration: 4GB RAM, dual core i5 1,3 Ghz CPU) or the mac mini core quad core i7, 4GB RAM with a regular hard disc?

LowLuster
No Air model can be as fast as a Mini with a quad core i7 CPU. Can't happen.
I didnt solicit your opinion, and it IS a fact, .....skilled users here on this board will and DO TELL other users OFTEN that:
"outside of processor core use (video/ photo etc.) you will NOT NOTICE ANY DIFFERENCE on X computer vs. slower Y computer"
I have a 8 month old QUAD core Mac Mini and it is , as I said above "noticeably not ONE BIT" faster than my current 2013 macbook Air with 8gig.
My quad core came with 4gig of RAM as I recall, I immediately tossed in 16gig.
Notice the word "noticeably"
Your subjective hyperbole aside, you are wrong......., those above yourself and myself (point wise,...as Ogel has stated, Clinton has stated, and others) state this fact very often regarding ---"outside of processor core use (video/ photo etc.) you will NOT NOTICE ANY DIFFERENCE on X computer vs. slower Y computer"
Its not my opinion, its a fact, namely additionally that I stated "noticeably" - "my quad core mac mini on MOST EVERYTHING (which is most things since 'most things' are NOT photo and video editing) is not "noticeably" ONE BIT faster than my Macbook Air.
"most things" people do (most people) on their computer does NOT involve photo and video editing (photoshop pro, final cut pro etc etc)
This is a fact, that AS SUCH most people WILL NOT notice any difference in general computer use between a quad core mac mini (for example) and a entry level macbook Air. (SSD vs. HD speeds aside). Nobody is going to notice faster youtube, or Word use, or websurfing, Acrobat Pro, Quicktime play, general APPS that havent changed much in 7 years.
Dont curse on these family boards please, its uncouth.
Peace
