HT4790 What's the point if anyone can log into Recovery HD?
What happens if I use Command-R and use the Recovery HD to log into the machine and erase (format) everything? Can this scenario actually happen? I mean, the Recovery HD won't ask for a password, so it would be pretty simple to lose everything or am I missing something here?

Yes, everything in OS X and Bootcamp, not the Lion Recovery HD

Yep, you can lose it all.

What is the point of having a smartphone if nothing ever works?
Before my GS3 updated to kitkat my apps would crash all the time. My phone updated last week and now the apps work but in what used to be areas with strong steady 4g coverage I have no data. So annoyed. I can turn my data on and without touching it I'll have 4g for a minute and then none before coming back for 5 seconds only to go out again. What am I paying for? My office doesn't have wifi and I have a large data allowance but what is the point if I can never use it? I do a lot of travelling and use my phone as a GPS but as I have no no longer have reliable service anywhere even in Philadelphia where it was a constant 4g. Not to mention the GPS is unreliable as well. Waze is an amazing GPS but to have a phone that doesn't work half the time is frustrating. I should just go back to my old flip phone that lasted me 2 days on a single charge. My phone is due for an upgrade in a few months. Maybe I'll save some money and get something that isn't a smartphone and I won't have to worry about paying for the data and everything else that comes with having a smartphone.
I can understand that Verizon did not make the phone. My satellite provider did not make the dish nor the receiver I use either, but if they malfunction and make it to where I cannot receive their service (the satellite signal) then the satellite provider assists in getting equipment that works. If it is a software issue, they have more sway with the provider of said software, as the representative and mass user of the software, than individual customers do. So if Verizon is receiving multiple complaints from their customers, complaints that their customers are unable to use the service that they are being paid to provide, then they can go to manufacturer to request the fix. Who do you think Google or Samsung is going to listen to more, an individual who received a phone from a 3rd party (Verizon) or the entire company who purchases those items (phones and software) en-masse and thus can more affect their bottom line? As another example... when you purchase a car and the seatbelt malfunctions, do you go to the seatbelt manufacturer or back to the car maker? Should each person who has a seatbelt malfunction go to the seatbelt maker or should the car maker issue a recall on all affected vehicles and offer a fix, provided from the seatbelt maker? When I go back to Samsung or Google, and IF they listen to me and initiate a fix, what priority is Verizon going to make it to get it out to their customers? Or is Verizon relying upon each disgruntled user to go find their own fix without it affecting them (Verizon) at all? Other service providers have already started issuing fixes according to my research... and if Verizon delayed pushing this update out for so long (as I've seen complaints that it was), why did they push it with these known issues and not insist before they pushed it out that Google or Samsung fix it first so as not to get these complaints? Sorry, but Verizon is at least partially responsible for my inability to use their service, as the provider of the equipment and software that I need to be able to utilize their services. I didn't go out on the black market and purchase this phone, I bought it at a Verizon store. I have not rooted the phone or in any way done anything other than add about 6 apps to the phone from the way it was provided to me by the store, and their required update - pushed across their cellular and data service - is what has resulted in my phone no longer being functioning. So yes, while Verizon may not manufacture the phone or the software, they are in fact the provider of said items to me and thus are responsible, and should be pushing back to Google or Samsung to get a fix for their customers. I was hoping to hear that Verizon was doing just that, but it does not appear to be the case.... Yes, other providers may be having the same issue, but I've seen them working with their customers to get a solution, providing CUSTOMER SERVICE to their customers, and that is all that I and others like me, have been looking for from Verizon in this kitkat fiasco and which they have been failing at.

i have recently purchased the highest storage but was unable to backup my phone via icloud, the button on my iphone to backup on icloud is grey out, anyone knows how to resolve the problem? What's the point of purchasing the biggest storage?
First check that your device is correctly connected to the wifi/internet (settings > wifi)
If your back up continually fails, you might try turning off back up on your mobile device (settings > iCloud > storage & backup) and then deleting the backup file from iCloud by swiping the backup file on the mobile device (settings > iCloud > storage & backup > manage…) and then turning back up on again.
If this doesn't help, try turning off some items for back up in a pattern to try to establish if your problem is being caused by specific data on your device.
Being able to back up to the cloud can be very useful, especially if you don't have access to a computer or have infrequent access to one, however unless you specifically need to use iCloud for back up, you will find backing up to iTunes significantly more convenient and possibly more reliable.

I want to know what I need and then how to take a pdf form I created in word and add the blue boxes so that anyone can type into my form
Hey john@adobe,
Could you please specify how exactly have you created your form.
You might need to have Acrobat installed on your computer to convert a word document to PDF.
Do you have Acrobat installed? If yes, what version? If no, then please try using the trial version of Acrobat DC (latest version) and access its features:
Download Adobe Acrobat free trial | Acrobat Pro DC
Also, let me know what kind of blue boxes are you talking about.
If you want others to edit your PDF form, then you need to make it a fillable form by choosing 'Form Editing' option from Tools pane.
Let me know more on this so that I can help you out.

I set up airport wifi with a WEP password, but it never asks for the password and anyone can enter my network...what to do?
Is it possible to backtrack your way out of the keychain?
Yes:
Run the Keychain Access utility found in \Applications\Utilities
In the category column (on the left side of the utilities' window), select "All Items."
In the right column look for your Network Name. It will have a "Kind" of "AirPort network password."
Delete every entry that has both your Network Name with this Kind.
What can I do to test or reset?
You can completely erase all the base station's passwords by performing either a "hard" or "factory default" reset. You can also temporarily disable these passwords for up to five minutes so that you will have enough time to change them using the AirPort Utility, by just performing a "soft" reset. I would recommend this one first.
This would also be a good time to consider using WPA or WPA2, instead of WEP, as WEP is no longer considered secure.
I got the airport extreme based used with no softward and set up with reset on airport base and followed instructions.
You can download a copy of the AirPort Utility, that runs on OS X Tiger here. -
What's the point of a contract when Verizon can cancel it any time?
I live in an apartment and have a two years contract with Verizon Fios which I signed back in Jan of this year. There is some issue in my apartment unit and my apartment management is transfering me to a ground floor unit in the same building. When I initiated the service transfer request with Verizon, they wanted me to drop my two year contract and sign a new two year contract with a significantly higher monthly fees. What's the point of two year contract that I signed back in January?
Technically you broke the contract by moving.

Hello people,
I'm wondering: what's the point in including code in a JSP using the
<%@include...%> directive if I must "touch" every single page that is including it if I want the modified verion of the included page to be reloaded by the server?!
Is there a way around this?
I know that including with <jsp:include.../> will have the server reload the included page if it has been modified.
But if I use this type of include, variables defined and intialized in the included page won't be visible by the parent page and that doesn't help me at all (or am I mistaking on this one? please tell me).
Thanks a lot for any help,
svevo.Hi guys, thanks for answering! :)
Still though what I'm reading here doesn't solve my problem:
using
<jsp:include page="myinclude.jsp" flush="true" />
doesn't let objects and/or variables in the including page to be visible in the included page and viceversa and that's a problem for the webapp I'm developing.
On the other hand files included with
<%@include file="myinclude.jsp"%>
are not reloaded unless the including page is reloaded as well (and that's a pain and makes including code this way basicly worthless IMHO).
What I need is a way to include code that will be able to use objects and variable declared and initialized in the including page and that we'll reload each time it is changed without having to track each single page using the included code and modify that as well so that is realoded by the server. Nor I can reload tomcat.
So, has anybody encountered the same problem?
Has anyone found a workaround for this?
Thanks a lot! :)

Unless I misunderstood, I have to pay to get all my music to be pushed to all my devices (iTunes Match) and I have to buy iWork for my iPhone (even though I already have it on my Mac) in order to get those documents pushed to the cloud. (It makes more sense to stick with iWork beta!)
I feel like Apple is nickling and diming its loyal customers.
So, essentially, iCloud is useless! I thought it would be a great way to free up space on my hard drive; I could just store my documents and music in the cloud.
My question is: what is the point of iCloud? Honestly, what does it do? It just pushes stuff between your devices? I genuinely don't understand the point of it.capaho wrote:

Here we go... Yet another 'loyal' Apple customer who seems to think that because they've bought one Apple product, Apple should forever let them have new products and services for free.
The real problem here is that Apple has no long-term commitment to support anything it makes. It wasn't that long ago that MobileMe (which was not free) came into existence and now it is already being dumped in favor of iCloud, which lacks the iDisk, remote access to Time Capsules and personal websites. It's a step backwards and a disservice to those of us who were using some or all of those MobileMe features.
Apple's product cycles, both hardware and software, are too short to be of use to anyone but those who like to play. Forget about trying to run a business from Apple products these days.
That is exactly right.
In my own small home network we 7 Macs all being synced through MobileMe. Only two of these Macs can run Lion and doing so would mean no longer being able to use applications that our clients still use so it would mean loss of these clients. Not to mention the cost of replacing at least 5 of or Macs.
Then there are businesses that have dozens of Macs or sometimes even hundreds of Macs along with gigs and gigs of data that Macs running Lion can't access. So even ignoring the huge cost of replacing al these Macs with newer Macs there is still the issue of Macs running Lion not being able to run needed applications.
With MobileMe one could buy a newer Mac running Lion and it would still be able to sync with older Macs but now it is all or nothing.
At least one design shop that I do work for is now replacing their Macs with Windows machines since these computers can run older software and also be able to sync with iOS devices using iCloud. At least a dozen other places that I do business are considering doing the same thing. -
What's the point of this code?
Hi, I'm getting an error in a program.
So I went to look in the code where the error is displayed.
And I found this:
z_nbjr = sy-datum - z_fromdt.
if z_nbjr > 1.
message is displayed.
Now, z_fromdt is the value TVARV-LOW for 'ZVDL_VBUK_LAST_RUN', and the message that is displayed is 'Please rebuild index file ZVDL_VBUK'.
Can anyone explain to me what is the point of this? What is TVARV-LOW?
And why do they make this check? And how do I rebuild the index file?>

As Pushpraj has already pointed out correctly, TVARV is where the variants are stored. It's rather strange that you've never seen fields like LOW and HIGH, because they're also used in the ABAP range tables (see Help for command RANGES).
Since this is all your custom development, we, unfortunately, cannot know what is the point of all this. I'm guessing that the message to "rebuild the index" is also custom and, therefore, you would need to find a documentation for the program in question or ask your colleagues what this could mean. Also check if there is a long text available for the message (although I doubt that).
Most likely it's some kind of an internal process of running some other program. -
What's the point of using a password?
what's the point of using a password if anyone can insert the installation DVD and choose reset password
As Barney-15E says, someone with physical control, can just remove the disk, and put it in an external enclosure, and mount the file system with their computer and access all the files.
Only encrypted data would be protected. There are data encryption facilities available on the Mac, both included, as well as 3rd party, including 3rd party whole disk encryption.
But having a password on an account, and engaging the password when the screen saver is active, can keep casual access from happening.
Also if you allow network access (file sharing, remote login, screen sharing), the password will keep random net users from accessing your system, when for example, you are in a coffee shop, or if someone gets onto your WiFi network, or you give a visitor to your home access to your network, or you allow a guest to use the guest account. -
Capture Conv: rev/reverse - what's the point?
Take this example from http://www.langer.camelot.de/GenericsFAQ/FAQSections/TechnicalDetails.html
public static List<?> reverse(List<?> list) { return rev(list); }
private static <T> List<T> rev(List<T> list) {
List<T> tmp = new ArrayList<T>(list);
for (int i = 0; i < list.size(); i++)
list.set(i, tmp.get(list.size() - i - 1);
return tmp;
}Now, I've read the JLS, the Generics tutorial, the JOT.fm article and the langer.camelot.de FAQ, but I can't for the life of me figure out one thing:
What's the point!? The wildcard version of reverse returns List<?> whereas the naive alternative (public static <T> List<T> reverse(List<T> list)) returns whatever you pass in. That seems much more useful! You pass in a List<String> and you get back a List<String> The JLS says that the templatized version "is undesirable, as it exposes implementation information to the caller."
My question is this: is that the real reason? It's not, right? What implementation information is exposed? The type parameter? How is that bad? Is it bad enough to reduce the functionality of the method?
I have a hunch that "exposing implementation information" is low on the tradeoff scale - and that the real reason for the wildcard version is backward compatibility. If you only had the templatized version, old code that tries to pass in a plain-old List to reverse would now generate unchecked warnings because of the conversion from raw List to the formal parameter's type List<T>. The preferred wildcard version doesn't generate unchecked warnings because the conversion from raw List to List<?> is 'safe'.
Isn't that right? The reason that "public static <T> List<T> reverse(List<T> list)" is bad is not because it exposes implementation details, but because it causes old code to generate unchecked warnings, non?
If I'm right, then my follow up question would be: who cares? Who cares if old code generates unchecked warnings? Isn't that fair? - a sort of gentle pseudo-deprecation of raw types?
And furthermore, if you'll allow me to smush several questions together, why the preoccupation with eliminating unchecked conversions all over the place? Doesn't the bytecode that comes out look the same either way? What benefit does an unchecked-conversion-free program or CompilationUnit have over one with such conversions? Does provability make possible some future JVM optimizations where some casts or instanceofs can be eliminated? I don't really see how, unless we're talking about some wacky static compiler. Why go to so much trouble to avoid unchecked conversions?Angelika, you caught me. I was writing about the 'void reverse(List<?>)' example from the JLS when I went back to your page and realized that your example had a return type. It confused the matter slightly, but not enough to detract from my main point, I thought. In fact, it seemed to prove my point - to provide a good counter-example to the JLS reasoning! But let me start from the beginning:
In the draft JLS, it mentions that<T> void reverse(List<T> list) {} is preferable to void reverse(List<?> list) {} which is "undesirable" because "it exposes implementation information to the caller."
What implementation information? The only difference between the two is that the 'unknown element type' has a different name. '?' as opposed to 'T'. In both cases, it means the same thing! A List with some unknown element type.
Whether it's called 'T' or '?' is inconsequential, it seemed to me. Perhaps one could argue that one is 'prettier' than the other but I didn't see how any implementation detail was exposed.
I didn't see any real reason to prefer the wildcard version over the other, except the reason I gave: the wildcard version avoids unchecked warnings for legacy code.
I now see that there is one other important difference - the type parameter T is actually part of the method signature. That could have important implications for overriding. In that sense, the 'List<T>' version does 'expose' and impose an unnecessary implementation constraint. I haven't thought through how that could be a problem, but I certainly can imagine that it might.
However, neither the 'avoid-unchecked-warnings-on-legacy-code' reason nor the 'typeparameter-is-part-of-method-signature' reason is mentioned in the JLS example. Without those two pieces of information, the preference just seems arbitrary.
So that was my initial question: "am I incorrect? The dont-expose-implementation-information reason seems much less important than the avoid-legacy-warnings reason - shouldn't the JLS mention *that* instead?"
THEN, to add to my feeling, I noticed that the similar-looking example on your page involved a return type of List<T>. It seemed to follow the JLS recommendation to its detriment! The preference in the JLS example seemed arbitrary yet harmless, but here it seemed actually wrong! In trying to avoid the hand-wavy concept of 'exposing implementation information to the caller', the usefulness and semantics were ruined! That seemed like alot to give up, just to spare legacy people some unchecked warnings. I thought this just drove home my original point about the JLS example - but instead it just made my question a confusing mixture of two different issues. I should have realized that and left the FAQ version out of the discussion.
Given all of that, consider now only the JLS's 'void reverse(List<?> list)' case and let me ask this refined question:
I think the JLS should say that '<T> void reverse(List<T> list)' is undesirable not because of the vaguely unconvincing reason that "it exposes implementation information" but rather because of these two explicit reasons:
. the type parameter is part of the method signature (which can cause strange 'gotchas' with overriding) and because
. it causes previously acceptable code to now unnecessarily generate unchecked warnings.
Does anyone else think differently?
POSTSCRIPT:
Of course, the thing I didn't realize was that that code snippet in the FAQ is crazy. ie. 'List<?> reverse(List<?> list)' is absurd! You would probably never do that. What kind of reverse method would return a List of a different parameterization than it gets? That would be a really weird reverse method, I think.
Given that, it seems to me that you should modify the 'reverse' snippets in the FAQ, under sections "What is the capture of a wildcard?" and "What is a wildcard capture assignment-compatible to?". I think you should do one of three things:
1. Make rev/reverse return 'void'. Then your example code becomes the same as the JLS, the wildcard version makes sense, and preferring it makes sense too.
2. Remove one of the two methods and only have 'public <T> List<T> reverse(List<T>)' which gives the correct implication.
3. Keep the example but give the methods a different name and purpose than 'reverse', like
'List<?> examineListAndMaybeReturnOneWithDifferentElementTypes(List<?> list)'. :) -
What is the point of having 17 apps if no one is skilled in that many disciplines anyway?
I have been told how having access to 17 apps is a really great deal. The problem is no one is skilled in that many different disciplines. Even if someone took the time to learn all that software they would still not be competent in all those fields. I don’t know any creative types that are really good at graphic design AND video AND illustration AND music AND the web coding etc. What good is access to all those tools if you don’t have all the skill to do all those different line of work?
I keep hearing people say “Isn’t it great to know that you could use all that software if you wanted to?” No! It isn’t! Having access to tools without the necessary skills to competently use them is pointless! I have worked in graphic design for about a decade and have been improving over all that time so the idea that I could just start a new field adequetly is redic! You need to have an entire team of people who work in many fields to do all those things really well. So my question is what is the point of having the software running off one machine with a license for only one user?@W_J_T (and MikeChambers)
“yeah you gotta be good at something rather than no good at anything, that is true. ;-)
I guess that is why I don’t understand this big push by Adobe to make their users become mediocre in many areas. Can you please elaborate on this point Mike Chambers? Why should I be bad at a lot of things rather then good at a few things? I don’t get it.
“As far as apps vs fields, the first thing many people wanna know is if you know the required software for the given task(s).”
On one hand I understand the need to have software skills on the other hand software skills without artistic talent does little good.
“Why that is I don't know, its rather odd and does not allow people the same ability to only focus on their more specialized sectors like in the past with the Creative "Suites".”
I understand the problem Adobe had with suites; all the products had to be released on the same time schedule which meant some were released way before they should have been. CC gets around that problem but Adobe hasn’t done a good job at telling why anyone needs all the apps.
“Did you just wish to have some dialog, or do you have a specific question or suggestion about things? I am kind of confused at this point sorry. ;-)”
It just seemed odd to me when I kept hearing these Adobe evangelists getting excited about the ability to use so many apps. I came here since I was hoping Adobe could explain why having apps in so many fields that you are not talented in is a good deal. So far I am still waiting for Adobe to answer that question.
“your passion seems to be solely the design aspect of things.”
Yes, it is but perhaps most importantly is the issue of time dedicated to learning a new craft. I have a good amount of design work so looking into a career change at this point doesn’t make sense for me. If I changed my career I would have to turn down design work that I currently have coming in and that would be a little silly.
