Why is there no graph?

Why doesn't the collections API include a graph implementation? A single/double edged and weighted graph might prove useful at times. Is it because these things can be represented with existing collections? If not, does anybody know of open source implementations of these types of structures? All I can seem to find are academic examples used for CS homework assignments.

you might look for a "charting" project instead. they tend to include abstract graph structures, e.g. www.jgraph.com (no affiliation, just the first link i hit).

Why are there so many more choices on the USA iTunes Store? Surely having an iTunes account should let you access all itunes availability the world over? Also how do you request films/tv series to the UK itunes?

Why are there so many more choices on the USA iTunes Store? Surely having an iTunes account should let you access all itunes availability the world over?
Also how do you request films/tv series to the UK itunes? There's tv series I'd like but they're incomplete like The Batman & Xena Warrior Princess. And films theta aren't available for download but you can purchase in a store like HMV? Apple isn't doing itself any favours by secluding countries by their store. They'd make billions if you could just select the iTunes Store you want to search & purchase from just by signing in! If anything what they're doing is putting themselves into a corner, other companies like Samsung & HTC are already on too of them for innovation & ease of use. The people they're attracting are predominantly existing Apple users not new customers. What do you guys think?

It's not Apple's choice, they can only sell a particular item where the content provider/rights-holder has granted them a license to sell them. Content is licensed by the rights-holders to Apple on a country-by-country basis, each country therefore has to have its own store, and you have to be in a country to use its store - they want control over where their content is available.
You can try requesting that an item be added to the UK store via this page, but unless the rights-holder agrees to then Apple won't be able to sell it here : http://www.apple.com/feedback/itunes.html

Why is there no way to delete all emails from my iphone?

Why is there no way to delete all emails from my iphone? IOS 7.1. Every other phone in the market allows you to 'select all' then delete.
This trick of selecting one, then holding move, then unchecking (and subsequently moving all the emails to trash) doesn't work. I've read these suggestions and while it appears to work the emails just show up again once you leave and return to the inbox. Perhaps it worked on an older version of IOS.
It blows my mind this is not a standard function. I get a few hundred emails at work every day, and most of the time I just want to delete all of them from the phone as I've read them already. Currently it seems i can only click edit and then have to check each email individually to be able to delete them at the same time; this is the definition of tedious. I would think there are millions of other iphone users who get their company email on their phones that must experience the same thing. It seems now i either spend 20 minutes a day deleting emails, or just let thousands of emails accumulate on the phone (taking up space and also making it hard to just review the most recent emails which is all I want to be able to do when checking email on my phone).
I am hoping I am just missing some simple solution here that everyone else uses. Please help!!

Only Apple could answer as to why there is no "select all/"delete all" function in the iOS mail app. Users have been bemoaning this lack of functionality for years now. Like everyone else, you can submit feedback to. Apple here.
Apple - iPhone - Feedback
While I understand the whole idea of being able to use the phone on the run, if you have an IMAP email account, and if you have access to a computer at work during the day, use your "select all" function on the server and delete all of the unwanted email there and it will be removed from the phone as well.
That doesn't solve the problem on the phone, but it gets rid of the email which is your ultimate goal anyway.

Why is there so much available space on my hard drive after installing Lion?

I just made the decision to go ahead and install the new operating system "Lion"
I backed everything up to my Time Capsule and I have an older back up of everything on an external hard drive.
Now I have two questions and one task.
Why is there so much available space on my hard drive and where did my iPhoto library go after installing the new operating system?
My task is to restore my most up to date iPhoto library which I assume is on my time capsule.
How should I approach this task?

Hi entresoft,
I am not sure how to do this. I am not a very literate computer person but have a vague idea of what you are suggesting.
If I do manage to figure out how to do what you have suggested will this restore my iPhoto Library and I assume maybe other files?
Thanks!

Why are there so many flash updates?

Why are there so many Flash updates… I have had two in the last week and at least one more since the start of the year. It seems to have really got silly this last 12 months, is Flash really that unsecure and unstable that it needs this many fixes and updates?
I know you can tick the install in background box when updating but I like to know what is going onto my computer and given Adobe's knack of crashing my system when using PS and AI I don't really want them silently installing anything.

99% of the time the update gets prompted by Youtube or BBC when videos won't play on there sites and I follow the links through them. You would like to think that big sites like these would not allow false links to malware to crop up, but it isn't out of the question. Next stop, up to date anti virus…..
As far as Youtube goes I thought they had adopted HTML 5 now as standard and didn't rely on Flash?

If i am the only user and owner of my macbook, then why are there 78 users in the directory editor?

Hi guys just wanted to know little bit about the open directory as my MacBook Pro has been playing up on and off at least a couple of years. I have been advised by Apple over the phone or as well as over the genius bar in trying to get my mac to behave. This normally solves whatever problem that has been happening at the time. "Great, job done!"... Not so much, as another problem eventually shows it's ugly pixelated face again and then we end up going round the Infinite loop ride one more time... And this ride ain't always free! I have forked out about £600 on it so far and it wasn't cheap in the beginning! Anyway I have just got off the ride and before I get punched by a plyst to get back on I would rather learn about the things I don't understand so hopefully I can resolve the matter without hair loss. So my main question so far is why are there 78 user names (most of which are computer related names, not all) are found in Directory Utility? I do not play games on my Mac it is mainly used for media such as iPhoto, iTunes, pages, mail and surfing the net. So which out these 78 users do I select as a server?
If you have any suggestions or pointers then please post a reply.
Thanks for reading
Orion

So which out these 78 users do I select as a server?
None. It's normal. Make no modifications.
It's not clear what trouble you are experiencing, or if anything is wrong at all. If your Mac is not behaving as you expect it should, describe what's wrong in as much detail as possible.
Include all relevant details regarding your MacBook Pro starting with which one of its three dozen models you have. Posting the results of EtreCheck will help with that. Read about it here.

After installing Mountain Lion, why is there Yahoo access for one user but not another?--both are administrators.

After installing Mountain Lion, why is there Yahoo access for one user but not another?--both are administrators.

We've had several instances where we have had to run chkdsk on arrays with over 1m files. Average completion time is approximately 72 hours. The maximum downtime window they have available is the 64 hour weekend window. File sizes and number of files were
much smaller then than they are now.
The idea, in theory, was to use VHDs to compartmentalize the data into smaller volumes which could be more easily managed. It would also improve performance when transferring these compartments of data as they would use sequential read/write rather than
fragmented/random. This idea was never fleshed out in entirety, they don't split data up into little containers, but simply into big ones per project. Hence the 11m files in one container that I am currently trying to diagnose.
Some other important facts: The VHD in question is mounted in B:/project/ as this server also allows remote workers to log in, but they are restricted to see only data in E:. Disks A-D are hidden via group policy.
Update: icacls is failing on a large number of files within this dataset. I counted the path characters to ensure it wasn't the 255 character limit I was encountering and verified that the paths being blocked are only about 150 characters long. Once it finishes,
I'll have to try taking ownership and then re-running it. At this point I still have no idea how long to expect. I'm running out of time as the environment will be in use again at 9AM tomorrow morning.

Why is there no scaling for high resolution monitors in Adobe Bridge CC?

Why is there no scaling for high resolution monitors in Adobe Bridge CC?
Photoshop CC, Illustrator CC and Indesign CC have 200% scaling for high resolution monitors in their preferences panel but Bridge CC does not, when will this feature be added to Bridge CC Adobe???

Inconsistency between or among applications in the artificial "suites" should come as no surprise.
The "suite" concept is a fabrication of Adobe marketing and bean-counting types. The engineering teams are totally independent of each other, they are not only in different buildings but in different cities and states of the American Union, even in different countries.
The fact that they have little if any communication among them is highlighted by requests occasionally made in these forums by top Adobe engineers to let the other teams know when there are problems in one application that impact our workflow in another one.

Why is there no support for RTF files in Pages?

Why is there no support for RTF files in Pages?
This is nuts!

You are not alone.
Actions speak louder than words, but Apple does manage to still distract many from what is self evident before them.
I am astonished by those who swear that non-existent features, or features that pre-exist the current version make Pages 5.2 a major upgrade.
An affect that does seem to wear off with familiarity, as each version of Pages 5 gets a boost in the App Store, only to see the disapproval rating surge back again.
Pages was always one of the top purchases in the App Store, now it doesn't even rate.

Why is there a maximum email attachment size?

I can understand why there is a maximum MMS file message size but why is there a maximum email attachment size set by the handset? The limit is preventing me sending pictures from my phone. MMS messages are charged at a flat rate but GPRS data is chared per kB. My operator, Tmobile, say they have no limit on email message sizes (and obviously they make more money if you send a larger file. If I transfer my sim card to my laptop or PDA I am able to send any size of attachment with no problem. But with the sim back in the handset a limit of 100kB is imposed. I get the same result using both Tmobile or Orange sims. This is especially annoying if you have a phone that produces high quality images with file sizes several times the limit. You can have a great image with no means of sending it at its original resolution. Anyone know why this is?

Most operator's (carrier's) MMSC (Multimedia Messaging Service Center) servers do set a limit.
What the MMS size limit that's guaranteed to go through is defined by a document known as the MMS Conformance Document (maintained by OMA, Open Mobile Alliance, which is a standardization organization by mobile device manufacturers and network operators, primarily).
So, both the handsets (phones) may or may not have a size limit depending on how it was designed, and in addition the networks also have their own limits, and they do not need to be the same, but the doc I mentioned specifies what the devices and networks have to support, at least.
