Excellent article.

Wow, there are so many "children" who hang out in the comments section on AppleInsider. It's just amazing.

They're children posing as smart people, but just demonstrating they can't sort out the complex world they supposedly work in. It's a testament to the complexity of the Information Age, and the fact that people just don't think about the need to "study a subject before commenting."

The author of this article has done his homework, and the children who hang out in the comments section should be good students and do the same.

To be fair Daniel is pretty biased at times. His table graphs are always slanted to make Apple look good, even if he's not aware he's doing it.

I can get that phone next month. With the numbers of sales and Android is has I'd be like I was in 1994 and stuck in a dying Market Share.

Apple may be great for stock holders but it's horrible at moving forward when they have an Advantage. History and now the current numbers are proof of that.

Good luck with the future and make sure you have Apple Care on your computers because you'll need it given Apple's trend for the last 10 years.

By the way...

How long has Steve Jobs been with Apple? I wonder why he was fired. Mac's don't "just work" anymore.

Go away. You are not positive contribution to this or any discussion.

If the author had done his homework he would know that the iPhone is not multicore and that the graphics part it's done by a GPU.

If the author had done his homework he would know that the iPhone can't do voice and data simultaneously while in EDGE or GPRS. It's not a problem of a terminal, but of the network.

If the author had done his homework he would know that runnig more than one application at the same time doesn't implies that you can install viruses or malware.

Putting his bias aside, he actually makes valid points. I have read many of his articles, and I think that he just goes to the core of the matter and illustrates it, even if he might be a fanboy

But to get back to the topic:
I hope Apple will implement some kind of multitasking in OS 4, but not the way WinMo and Android have done it. I like the idea about thread-saving or application suspension, to make sure that the state of the application is saved, but without giving it any processing time. For the apps that require processing time, I hope they come up with something like mini-processes, which do simple stuff with limited resources.

IMO the most difficult part in this is the UI, as you would need an easy way to now what is running in the background, or which applications are suspended.

I don't buy the arguments against multi-tasking at all.

Battery Life - It's my choice if I multi-task or not, and as my iPhone 3G has already used half of it's battery by the time I get to work I have no choice but to plug it into the mains anyway.

Memory - Would it be so hard to bring up a little pop-up which asks me if it can quit other running apps to free up RAM?

Can't see what's running in the background - Make the icon of a running program glow or be highlighted somehow. If I tap on it, it pops right up, if I hold on it, I can kill it. A simple double tap of the home button or a gesture of some kind could flip between running apps.

Bottom line, multi-tasking has been standard on computers for decades now. The iPhone is, so I'm told, a portable computer, so it must learn to multi-task. Not being able to listen to Last FM and read an IM is simply retarded.

First off, this functionality is already built into the OS X kernel and has been since day dot. It's dead easy to 'freeze' a currently running process and then start it running again sometime later. You can try this for yourself:
  • Open two terminal windows
  • In one of them run 'vm_stat 1'. This will produce a constantly updating list of virtual memory statistics at 1 second intervals
  • In the other Terminal window type: 'killall -STOP vm_stat'
  • Have a look at the vm_stat output now. It just stops. You will probably also see a message saying "[1]+ Stopped" because stopping a processes like this forces it to become a shell background process as well.
  • Back in the command Terminal, type: killall -CONT vm_stat
  • The vm_stat process will start running again, continuing from where it left off.
  • To get rid of vm_stat completely either type "fg" to bring the process to the foreground and then terminate with ^C, or just close the Terminal window.

This would enhance the iPhone OS's existing, simple model of switching between apps without introducing a drain on the system's processor, memory, and battery life, as only one primary app would still ever be running at once.

Um you're correct to say it wouldn't introduce a drain on the system's processor and battery life, but you're wrong about the memory. Have you ever seen demos of other multitasking phones where someone tries to start an application and gets an "out of memory" message instead? Stopped/paused/frozen processes are still going to hang around in memory unless there's a specific action to save that used system memory in Flash (a.k.a paging out to swap) to make room for the next app. This would introduce a delay in app switching that might be very noticeable due to the general sluggishness of Flash: though there are a number of smart things Apple could do to try and speed up this process.

Wait a minute....
One minute you're saying that Android is 'shipping' 60,000 devices per day, and withing 15 minutes that's risen to 160K/day?
Someone's smoking the Google crack here.

Listen... you hate Apple and the iPhone, and think they should design the thing specifically to meet your niche needs. Fine. Bad mouthing the vast majority of buyers out there (pre-teens?... please....) who want a working appliance rather than a fragile tinker-toy set will make you popular amongst a rapidly shrinking percentage of self important elitists. Enjoy their company... those of us with lives to live instead of science kit project phones to worship will stay en masse with the device that is solid. That would be the iPhone for me.

I hear there's a lot of space over one the AndroidInsider site.

Really? "You find". You don'T understand the OS, so what you find isn't what's there. you're the only one who seems to want us to believe this. Even those who prefer other phones wouldn't say such a thing.

This idea that their is not enough memory or battery life is garbage. It has already been shown in tests that, with a jailbroken 3GS, someone could have 5 apps running in the background with no noticeable lag. It can run with lag 10-12 apps (some games included) in the background. Check out the justanotheriphoneblog's testing of Multifl0w. If you are running something like iStat on your 3GS, check out the memory usage. You will find that you are using very little of the 256MB of RAM it has.

You cannot really just make a blanket statement because every app does not function the same way and every app does not use system resources the same way. Some developers will be better skilled at making their app run more efficiently than others.

The point is if/when Apple allows multitasking it will be with rules that force developers to do all of the hard work so that the end user does not have to deal with allocating system resources at all.

So true. Not too mention the first evidence of malware on the android marketplace are beginning to crop up.

Plus, no ones even mentioned how difficult tech support is to come by for these phones.


Personally, I live my iPhone for all the qualities others claim are detractors. My phone has literally all the information of my life stored on it. All my contacts, all my emails, my account information, my location habits, EVERYTHING. Personally, when it comes to a phone, the last thing I want is an open marketplace and an open process arena for Trojans and keyreaders and the like. Other than the obvious pandora, I've never once thought to myself, damn if only I were multitasking this would be such a better experience.

The only major change I'd be interested in would be concurrent apps, where closing one app just saves it's current state. If there's enough ram for this to be an option, irbetter yet a way for the developers to just save the current state to the flash drive, that would speed up the time it takes for me to say, leave a news reader, type a chat, and re-enter the article in 1-2 secs rather than 5. Not a huge issue, but could be fun.

The last things I ever want on my phone are physical keyboards, open app stores, open multi-tasking or multiple drastically different hardware platforms running the sane hardware. All of this barely works on PCs with their driver issues (still plague vista and 7), malware and virus attacks, completely freezing up decent computers with too many concurrent process, etc. Why port those issues to phones when all of the diendildes are totally unacceptable in a mobile environment

I'm not interested in any of that crap you mentioned. I love my iPhone 3G and my MBP unibody. If Apple made a mid range tower, I'd buy it in a second. But I can't help but notice all the Orwellian doublethink that goes on among Mac fans and I point it out. Two years ago these people were saying Apple didn't need to allow third party apps, now they celebrate the app store as the defining feature. As for your condescending remarks - you spend all day on a computer forum, reading every post and replying at length. Nuff said. Some of us have a life.

If you had a life then why are you arguing something like this here?

You might notice, in that life, that Pre fans, Android fans, Win Mobile fans, and others are ALL thinking their phones are best, and wishing away the negatives.

I love my iPhone but I also understand that what makes it so special can't be explained in a table. Daniel tries and fails. His tables are always full of bias, cherry picking and curiously missing data.

The table in this article is incredibly flawed:
  1. It fails to include the two biggest (by marketshare) smartphone platforms.
  2. It mixes up operating system capabilities with network capabilities. This is akin to saying that a Ferrarri has a maximum speed of 70mph because that's the national speed limit.
  3. States that PalmOS can't multitask when, in fact, its kernel can and does. Hence its ability to receive a call whilst doing another task. Multitasking on PalmOS just isn't open to 3rd party apps, just like the iPhone.
It's nonsense.

Admittedly, I do read the comments made to my 'Ignore' listed such as yours. It helps me decide who to add to the list.

Now if there was a way to automatically 'one-line' your reply for example so I never have to see any of the 'ignoreder's' original posting unless I want to.

Nope. We are just saying that no body wants Multitasking the way it is done on other platforms. And if you read the article carefully, I think it states that some kind of "multitasking" is needed, but this word has come to have a lot of different meanings. And the author points out the meanings we would want to get implemented, as well as those we don't want.

Talk about cherry picking data.

And let's get real about this "can't handle voice and data simultaneously" BS. That's a limitation of the network, not the OS. Why is it included on a table listing operating systems? It's irrelevant. If we are going down that rather dubious route then why is there no mention of the fact that most GPRS/EDGE networks can't handle voice and data simultaneously either?

It is a limitation of the networks, as was made clear in the chart.

Well,

First and third links are a proof of concept, like so many proof of concepts of OS X virus.

The karspersky link says nothing about ACTUAL malware and it talks about iPhone also.

MemoryUp virus link is erroneus, it wasn't a virus or malware according to Google.

So, despite the years that WinMo has been in the market there is only ONE case of a trojan (not a virus) which can't spread and a proof of concept of a virus that doesn't work in the wild.

None of us are saying we don't want multitasking. We are saying we understand why Apple has not implemented it. We'd prefer they figure out a better way to do it instead of just slapping it on there just to fulfill a feature check list.

I don't remember anyone saying the iPhone did not need third party apps. In fact Apple announced that their would be third party apps two months after the launch of the original iPhone. So we knew it was coming nearly a year before the App Store was launched.

That's not really true. Besides that have been other virus's, I just don't have to time to look for it as I have to leave in a few minutes. There has been malware as well. Android has already had its first scare in that area.

He was showing, as the title "What is Multitasking?" the different forms of what could be considered multitasking, and that it's available to some phone and network systems, but not to others (yet). Not all multitasking to the user is only through the phone hardware alone, some depends on which networks are being used. Therefor, its a valid comparison.
post #111 of 275

Only the last one was an Android article and it's wrong. In the first place it wasn't a virus. It was an app that was *supposedly* gobbling up memory. Secondly, the app was doing nothing of the sort. On the Android, like any other Java system, memory is managed by the JVM. Finally, to access specific APIs, you need to ask for permission in the manifest. When installing an app, the list of access required is displayed to the user.

In case you are interested, http://developer.android.com/guide/t.../security.html

Which is not to say that you can't have a phishing app - just like on the iPhone. If you are going to enter your bank credentials or your Google account information, you had better be sure where you got the app from - and that applies for the Android, iPhone, Desktop or web.

Forget iPad, my Powerbook is now exposing what appears to be poor quality of the OSX scheduler and process priority schema.

I open my laptop from sleep and have to wait 30+ secs while it fumbles about in the background due to things like Mail, before it manages to schedule my login pane. PATHETIC.

My login pane should come on immediately. No arguments. Mail can wait. Login should be boosted to operate above the main background and even regular foreground priorities.

Window tab flipping should operate above any activity within ANY tab.

Window minimising, moving or expanding should operate at a higher priority than regular process.

This does NOT happen. Safari churns on some abstract link , DNS, Flash or whathaveyou, sometimes not using much CPU but can you close the tab? No. Can you close the window? No.

We have lost (thank god) co-operative multitasking but boy do we appear to have "co-operative windowing" which, frankly, does not help us that much when what we want to do is exit a pane, tab or window and the process is not "interested".

The window should not be under control of the application, it should be under control of the window manager. I do not want to have to ask my applications to minimise, I wish to TELL them.

All I know is, OSX lacks basic functionality that I took for granted with the "big iron" OpenVMS I used to use.

which allows different tasks to run concurrently on different processor cores.

For example, when playing back video, the iPhone can spin off the heavy lifting involved with decoding H.264 to a specialized video processor core while the [b]main processor core continues to handle other tasks, such as listening for updates and maintaining the user interface

I've never read about cores if it is monocore. In every tech article when there is a CPU and a GPU they say processor, not core.

But as he is trying with the term multitasking, perhaps he wants to redefine how people names processors and GPU+CPU couples

That wouldn't be fair at all, you're just responding like that because you want to jump to his defense no matter what. Normal fanboy reaction. I pride myself for never failing to criticize Apple, which there are numerous opportunities for--he wouldn't dare. I never said "inaccurate", I said biased. And he's meant to be the journalist, so he shouldn't be at all biased. It's quite common for a regular user here to call him biased, it happens all the time. His articles are always biased, everyone knows this. He did a history of tablet computing, in which he takes his usual sudonym of "Prince" and forgot to talk tablet computers.

To paint a complete picture of the situation with PalmOS, note that despite the fact that there is no official means for 3rd party apps to multitask, there are individual exceptions.

For example, any PalmOS based smartphone still has to have a process running in the background to detect the event of an incoming phone call, just the same as would be the case in the iPhone.

Most of the PalmOS 5 handhelds have included MP3 players from various authorized 3rd parties such as RealPlayer. Those MP3 player apps had special hooks that allowed preemptive background playback of music.

Way back when US Robotics was designing the operating system for the first Palm Pilot, they chose to license a kernel from a 3rd party rather than write their own, and then customize their own user environment on top of it. The kernel they chose was technically capable of multitasking, but the license they negotiated for its use specifically prohibited exposing the multitasking API for use by applications. This kernel was used throughout Palm's time using 68K CPUs.

Palm OS 5, released at the same time as Palm switched from 68K to ARM, was designed with a seemingly exclusive focus on maintaining backward compatibility with older software where multitasking didn't exist. The backwards compatibility was so complete that the emulated 68K environment was the default state of the system. Whenever any application launched on Palm OS 5, it always started out life as an emulated 68K app; any ARM-enhanced portions were small subroutines which were accessed by "escaping" out of the 68K emulation layer.

O so Apple will only let ITS software run in the background because otherwise we could have viruses and heaven forbid the Mac OS get a virus! I'm sorry but thats a weak way to defend against viruses and its a big way of hendering development. As a information security analyst you look at balance between useability and security. In this case Apple has severely hendered useability for security. That would be like Microsoft making it where you can't install anything but Microsoft products on Windows and thats what makes it Apple :P
