Is back up really necessary

In the event of anything untoward happening when I install SL is it not just possible to put in the original Leopard Disc? Do I have to back up my system? I could back up any of my documents and put these on a memory disc. Its just that it seems such a hassle to have to get an external drive as well. I never backed up my drives in the twelve years I was a PC person although I did save stuff to a memory stick, but not the whole system.

I suspect what the OP means is whether it's worth backing up the Operating System and his data before upgrading.
If you have your data, and you're happy to reinstall the Operating System, Applications, and the look and feel (I.e. how you've personalised your install) then I guess no you don't.
On the other hand I'd rather have too much backed up rather than too little
The answer above stands - don't backup what you wouldn't care about if you lost.

Is 'Leopard' really necessary?

Hi again..
I've been reading different threads on this topic (some of which were negative on various Leopard features) and was just wondering whether it was really necessary to install Leopard?
We only recently bought our Mac and I was just concerned that I might end up with unnecessary problems....
What are the benefits of (or purpose in) installing this software/upgrade?
Any information on this would be appreciated, thanks!

After one week using Leopard, I was ready to say it was far more trouble than it was worth. Against my better judgement, I decided to do the default "Upgrade" install, but not before I made a clone of my Tiger startup disk, & it would have been a nightmare without that. The install seemed to go fine but my iMac would not restart completely -- no menu bar, no Finder, & a stuck Dock. I tried a lot of things but ultimately had to erase the drive from Disk Utility on the Leopard DVD -- Erase & Install would not even work from within the installer, repeatedly giving me a message about not being able to unmount the target volume. But after around 12 hours total effort, I successfully installed it 'from scratch' on the newly reformatted drive & used Setup Assistant to migrate everything from the clone.
I have no idea why I had these problems: I had used Tiger's latest version of Disk Utility prior to the first attempt to verify that the Tiger install had correct permissions & that the file system was OK. I had no third party hacks installed (& I'm obsessed enough about the evils of such things to know how to find them, even when stuck into the nooks & crannies of the OS). "Clean" is an overused term, but my Tiger OS was as pristine as I know how to make it, drawing on almost two years of active participation in these forums & everything all its gurus taught me.
Anyway, even after getting it installed successfully, & doing everything suggested here & elsewhere to make sure it was in good health, I had a variety of small & not-quite-so small problems. The 10.5.1 update helped some, as did Apple's k-base articles about repairing oddities introduced by upgrading from Tiger & such, but it still was disappointingly unstable compared to 10.4.10. Worse, I learned that several of my mainstay apps weren't Leopard-compatible.
But I stayed with it, partially because I could always reboot into Tiger with my clone when I needed to, partially because I'm just stubborn enough not to want to admit defeat, but mostly because the new feature set really does have a lot to offer that Tiger does not. The biggies like Time Machine are great but I find all the little refinements are really what I like most. For example, I didn't think something as simple as being able to display the path in the bottom of all Finder windows (like in Spotlight searches) would be such a boon, but it is. Spotlight is still far from perfect but Boolean searches make it much more powerful.
Long story short(er), I find that when I need to boot back into Tiger, I really miss all the little things it won't do that Leopard will. There are still some rough edges & things that need to be rethought, & it still isn't as stable as I would like but overall, as the two months of use mark approaches, I do not regret buying it & making it my mainstay OS version.
Necessary? No. Worth it? It is for me.

Are third party disk utilities really necessary?

Are third party disk utilities [such as TechTool Pro or Disk Warrior] really necessary on a G5? Does the Apple Disk Utility perform all necessary repair functions?

need a DiskWarrior for sure - buil-in utility is not very powerful for real nasty file corruption.
most important is to back up files regularly to another drive - if drive fails no utility will fix it.

What is MacKeeper - is it REALLY NECESSARY

Is MacKeeper REALLY necessary - as I am not having a problem with slowness. Princepony

Apps like MacKeeper or any other maintenance apps like CleanMyMac 1 or 2, TuneUpMyMac, MacCleanse or anything like these apps, installed on your Mac, while they appear to be helpful, can do too good a job of data "cleanup" causing the potential to do serious data corruption or data deletion and render a perfectly running OS completely dead and useless leaving you with a frozen, non-functional Mac.
Plus, these type of apps aren't really necessary OR needed. They really aren't.
There are manual methods to clear off unnecessary data off of your Mac that are safer and you have complete control over your Mac and not just leave a piece of auto cleaning software in charge of clearing off data off of your Mac.
These types of apps potential of causing OS X issues outweighs the implied good and benefits these types of hard drive or memory "cleaning" apps are written to do. Plus, the software companies that write these apps make it hard to easily uninstall these apps if something DOES go wrong and these apps work in a way where you have no recovery or revert function to return your Mac back to its former, working state in the event something does go wrong.
That is because of poorly written code. The companies that write these apps are only interested in one goal...to scam/rob you of your hard earned cash for a piece of software that will be more harmful to your Mac than good for it!
It is best to never, EVER download and install these types of apps.
The risk to your system and important data is too great a risk!
Stay well clear of any of these "cleaning" style apps!

Restore my iPod touch can make me lose everything I have and is it really necessary? // Restaurer mon IPod touch peut-il me faire perdre tout ce que j'ai et est-ce vraiment nécessaire??

Hi everyone!
I have problems with my 4th generation IPod Touch for a while.
First, it was no longer recognized by Windows or by ITunes and yet il worked fine forabout 2 week.... it is beyond comprehension!! Ican no longer use ITunes... not pratical!! I'm actively looking for solutions.
I finally solved the problem of recognition with Windows, with the help of Apple. Now, I still have the problem of recognition with which ITunes still does not work. When I open ITunes, a warning message telling me to restore my IPod.
My fear is losing my music but also some conversations, my bookmarks, my pictures and my apps and data entered in them. I would lose nothing, find my IPod as it's now after the restoration.
Is it possible to not lose its data during a restore?? If so, how?? Is ICloud does the work??
Is it really necessary to restore my IPod?? Do you think this would solve my problem really??
Could you please help me???
Thank you in advance for your answers!
Zazzz
P.S. Sorry for my English..... I'm French!!
Bonjour à vous!
J'ai des problèmes avec mon Ipod touch 4e génération depuis un bon moment.
Tout d'abord, il n'était plus reconnu par Windows ni par ITunes et pourtant il a bien fonctionné durant environ 2 semaines... c'est à n'y rien comprendre!! Je ne peux donc plus utiliser ITunes... pas pratique!! Je suis donc en recherche active de solutions.
J'ai finalement résolu le problème de reconnaissance avec Windows, avec l'aide Apple. Maintenant, il me reste le problème de reconnaissance avec ITunes, qui ne fonctionne toujours pas. Lorsque j'ouvre ITunes, un message d'alerte me dit de restaurer mon IPod. Ma crainte est de perdre ma musique mais surtout certaines conversations, mes signets, mes photos ainsi que mes applications et les données entrées dans ces dernières. J'aimerais ne rien perdre, retrouver mon IPod comme il est maintenant après la restauration.
Y a-t'il une façon de ne pas perdre ses données lors d'une restauration?? Si oui comment?? Est-ce que ICloud fait le travail??
Est-ce vraiment nécessaire de restaurer mon IPod?? Croyez-vous que ça règlerait vraiment mon problème??
Pouvez-vous m'aidez svp???
Merci d'avance pour vos réponses!

Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
Connectez-vous via le câble à l'ordinateur que vous utilisez pour la synchronisation. A partir d'iTunes, sélectionnez l'iPad / iPod, puis sélectionnez l'onglet Résumé. Suivre les indications pour la restauration et assurez-vous de dire «oui» à la sauvegarde. Vous serez averti que toutes les données (applications, musique, films, etc) seront effacées, mais, comme les finitions de restauration, il vous sera demandé si vous souhaitez le contenu de la sauvegarde à copier à l'iPad / iPod. Encore une fois, dire «oui».
Sorry for my French. I'm an American!

Is 2 GB Ram really necessary?

Looking to upgrade my gf's Macbook.
1 GB = $99
2 GB = $225
Given OSX's good memory management quality, and the fact that she will mainly do web design and LogicPro 7 work on the Macbook, is the 2 GB really necessary or will it be more like overkill?
We had 2 GB in our old powerbooks and it seemed to make little real-world everyday difference between 1 GB of Ram.
Thanks for any comments...

I'm running 2G of Ram with Logic Pro 7. It's well worth the money if you can afford it. And it also depends on what you're going to within Logic Pro 7. But so far, I've noticed a HUGE difference...things are running a lot smoother than before the memory upgrade.
Having said that, 1G should be sufficient. Of course, Logic Pro 7 is running Universal. So you're going to get your money worth. And plus, your gf is going to love you for the 2G upgrade.
Web-design takes less "stress" than using Logic. But then again, if she's a professional web-designer and going to use Photoshop with it...keep in mind that it's not Universal yet. But when the update is ready, I'm sure it will fly with 2G of Ram.
Not all 3rd party plug-ins for Logic Pro 7 are universal yet...so performance is going to suffer a little when running those plug-ins.
Live 5.2 is UB and Reason 3.0.5 is also UB. If you really want to surprise your gf, get these 2 music production softwares, she will love using them with Logic Pro 7. I know, I'm a little off topic, just some suggestions. Any day is Valentine day.

Is the rating system really necessary?

I know... I know... I'm probably getting on a touchy subject here.
I understand the desire for a sort of incentive for people to answer questions but it is my observation that use of points is hardly consistent. For the most part, it seems like questions from established users tend to get helpful and solved answers most of the time. Great. The point system works in that instance.
I have also noticed that I will see someone come on the boards, post a question, get their answer and never post again. They either don't know about the rating system or they do not stay long enough to use it.
Does that mean I need to look at the O.P.'s post count before I post an answer? I think that's shallow. If someone has question and I think I know a solution, then I will post a solution.
But what is the solution? Do away with the rating system? I think some upper-level members would have a justifiable objection to that. Change it to a raw post count? I suspect we would see an even higher number of posts deleted because of people trying to pad their numbers.
What if members received 1 point for marking an answer as helpful and 2 points for marking an answer as solved?
Its a thought.

No, the rating (reputation) system isn't really necessary, but it does serve as an incentive for many people to increase their participation, and increased participation lends itself to the perception of increased value in this Apple-provided service, if not to the usefulness of the bulk of the posts that are left here.
Ultimately, there are a lot of things that go into the decision to attach a reputation system of one kind or another to Discussions, and there has been one such system or another in place here for many years, so there is no reason to believe that the concept will ever be abandoned.
As to the idea that upper-level members would object to its loss, yes, some would. Maybe many. On the other hand, there are quite a few of us who see through this charade and do what we can do undermine its importance relative to the real mission of Apple's Discussions. In the end, I'd like to think that our cynicism helps to balance out the "shallowness" of post-count building and points-grubbing strategies that seem to obsess many of our peers.
What if members received 1 point for marking an answer as helpful and 2 points for marking an answer as solved?
I've suggested this myself in the past, but one of the roadblocks to its implementation is that the current software is only able to mete out points in increments of 5. Oh well....
Good luck!

[Solved] Is HAL really necessary?

Hey ,
I used Arch a while ago, but started distrohopping again, since I didn't want to put so much effort in configuring my system. But now I feel ready to give it another shot
For a few days now, I've been reading the Wiki; and now I'm not quite sure if HAL is still really necessary. I mean, udev can do pretty much the same things, right?
And I'm only using my laptop for surfing, office-stuff & as a mediplayer (my music is stored on a ntfs-formated usb-hdd.)
I'm still really new to the whole Linux-thing, so maybe I'm completely wrong; please correct me if I am
Greetings from Germany,
mT

On the xorg wiki page it says
"If you are using Xorg 1.8 you do not need to add HAL to DAEMONS array or start hal"
so if you use xorg 1.8 you don't need hal ( which I think is still not in the official repo , but you can get it from AUR )
I hope that helps

FK's indexes : really necessary ?

Hi all,
I have a database with an index for each Foreign Key. This leads me to wonder whether theses indexes are really necessary ?
I read elsewhere that a query like this one would help me to see which indexes are really worth it (the bigger the ratio, the best the index) :
select distinct_keys/num_rows as ratio, distinct_keys, num_rows, index_name
from user_indexes
where num_rows != 0
order by ratio;Can anyone confirm this is a good clue, or give me some more advice
Thanks for your comments

I found information on this topic here : %20and%20{key}]http://asktom.oracle.com/pls/ask/f?p=4950:8:71095::NO::F4950_P8_DISPLAYID,F4950_P8_CRITERIA:292016138754,{foreign}%20and%20{key}
It says that indexes on FK are necessary to prevent table-level locks.
Now my question is : what if statistics are not set for theses indexes ? Will Oracle ignore them and lock the tables ?

Is Iterator class really necessary for our lifes?

I'm reading about Iterator class and how to use it, but a doubt arrise. Is it really necessary?
Take a look at my code bellow:
import java.util.*;
public class Main {
    public static void main(String[] args) {
        ArrayList ar = new ArrayList();
        for (int i=0;i<20;i++)
            ar.add(i);
        //Method 1
         for(int i=0;i<ar.size();i++)
            if (((Integer)ar.get(i) % 2) != 0)
                ar.remove(i);
        //Method 2
        Iterator it = ar.iterator();
        while(it.hasNext())
            if (((Integer)it.next() % 2) != 0)
                it.remove();
        System.out.println("The even numbers are: ");
        for(int i=0;i<ar.size();i++)
            System.out.println((Integer)ar.get(i));
}In the code above, we have two ways to do the same thing, both works fine, but using the Method 2 I needed to code one line more instancing a new class Iterator.
Can anyone tell me in which circuntances I really need to use a Iterator and why?
Thanks

Additionally, Iterator works on all Collections. For Sets, there is no get(i). If you have a method that returns a Collection, and that Collection might be a LinkedList or an ArrayList or a HashSet or something else, the Iterator is the gauranteed way to walk through it, regardless of what class it is. And with enhanced for loop, it's quite clean and simple.
Collection<Thing> things = thingFetcher.fetchACollectionOfThings(); // LinkedList? HashSet? We don't know and don't care
for (Thing thing : things) {
thing.doStuff();
}

Is periodic maintenance really necessary?

Is it really necessary, and does it really accomplish anything? And if so, why isn't it mentioned in the user-pamphlet that came with the machine?
I've read several threads about running "sudo periodic daily weekly monthly", and whether or not it will get run automatically if the machine is asleep or powered off at the scheduled time, and how to run it manually or download tools to automate the process.
But I've also seen some things saying it doesn't really accomplish much.
It seems like if it was really necessary that apple should advertise it better and make it more straight forward for novice users to do it.

Not true. If the Mac is asleep at the appointed hour of the maintenance scripts execution (3:15 am) the scripts will run soon after the Mac is awakened. But if the Mac is turned off at night, the scripts do not run when the Mac is booted. The countdown clock is reset to 0 and if the Mac is consistently shut down before 3:15 am, then the scripts will never run.
It has already been established in another thread that the OP shuts down his Mac every evening and his Mac's scripts have not been run for some time.

CU51 really necessary?

Hi all,
We enter KMAT and configuration values in SD order.
In order to have our BOM exploded according to configuration in Production order, we need to go CU51 and save the configuration.
The question is, CU51 is really necessary for activating configuration ? Because we never change anything in the BOM over CU51, which is to explode according to Sales order item characterictic values. I wish, the BOM explodes in production order appropriately without visiting CU51
Thanks

In order to ensure that an order BOM is exploded, one of the following steps must be performed:
Before saving a sales order in the transaction VA01 or VA02, make sure to go to "Engineering" from within the configuration.
Save the Order/Item in the transaction CU51.
Activate the switch GV_FORCE_BOM_EXPLOSION_ASL (Include LCUKOFBE) from SAP note 303446. This switch forces an explosion of the order BOM from within the sales order, without going to the "Engineering" view.
Use the report RCU_CU51_DARK from SAP notes 371188 and 384624.

Is it really necessary to download your Blackberry OS from a specified carrier like this one? :https://swdownloads.blackberry.com/Downloads/entry.do?code=4558DBB6F6F8BB2E16D03B85BDE76E2C

Device operating system releases are "released" by specific carriers once they have certified and trained their support techs, but still, you are able to load to any carrier's same model by following specific instructions.
Some users might worry they will void their device warranty by loading an OS from another carrier. There is really nothing to worry about. Please read more information on that here: http://www.port3101.org/power-users/296-blackberry-os-upgrade-including-betas-myths-dispelled.html

Is a PDF reader really necessary on iPad?

Is a PDF reader really necessary for iPad? I haven't needed one yet ... I don't think.

Depends on what you want to do with the PDF's and how you're getting them on the iPad. Originally, when the iPad came out in spring of 2010, there was no native PDF reader (except for emailed PDF's). Goodreader was one of the first apps to cater to PDF reading, and others came up, so there are a number of PDF apps. As time went on iBooks was given PDF ability, and for most people that's fine, but apps such as Goodreader have additional features.
If you haven't needed one yet, don't worry about it - just use iBooks or the mail reader. If you find yourself in need of a more sophisticated app, then just visit the App Store and see what meets your needs.

Is DPS really necessary to create an Android app?

Is DPS really necessary to create an Android app? I ask because I'm trying to create my first app and a colleague of mine bought DPS but then cancelled his subscription because he found a tutorial that showed that all he needed was InDesign (he's running CS6 on a Mac but I'm running CC(2014) on a PC running Windows 7). When he selects a folio in the Folio Builder and then selects the options dropdown in the top right hand corner of the box he has an option to 'Create App' but for me that doesn't exist. Can anyone explain this please?
I have so far managed to upload my folio to the DPS Dashboard and from within that I have published it, tested it on my Android device using the 'Adobe Content View' that I downloaded from the 'Google Play store' and I've also exported my app from the DPS Dashboard as a .zip file. What I can't do (or don't understand how to do) is the next bit. How do I get from the .zip to an app with its own icon. Do I have to purchase a DPS account to go any further? Also worth mentioning is that I don't want to upload this app to the 'Google Play Store' as I only intend it to run on a few tablets.
Thanks,
Joe

Thanks Bob, can I also ask...am I right in thinking that a single-folio app cannot be created for Android? What I want to do is simply have a single page view divided into six areas and clinking on one of the 6 areas plays a video full screen and then at the end returns to the page showing the six videos...nothing fancy!
Thanks,
Joe
