Still As Life

I received a completely unexpected present from a good friend of mine a couple of months ago, a new Palm Treo 750 running Windows Mobile 6.

I am quite fond of the design of the Palm Treo’s as they manage to incorporate an (almost) full keyboard along with a reasonable sized screen (240px * 240px) without the need to use a sliding keyboard. Sliding keyboards are prone to getting broken much easier in my experience, especially when I’m using them.

Unlike it’s predecessors and most other Palm phones, the Treo 750 runs Windows Mobile instead of Palm OS, and there have been some interesting things implemented in Windows Mobile by Palm. To my understanding, Palm have an exclusive license with Microsoft, allowing them to actually modify Windows Mobile 6.

One of the things I find the most useful is how it displays SMS and other messages in the form of a conversation, similar to how Gmail displays emails, and how Palm OS displays messages received. The addition of a search box on the Today screen is also extremely useful. Simply start to type a number or name and it will search your contacts and make suggestions as you type.

I have noticed news and rumours popping up, as well as some releases on Apple’s website about the next version of OS X, due out next year, Snow Leopard. Just going off the information directly from Apple, Snow Leopard is sounding like it is going to be a very interesting release and as an unashamed Mac fan, I am eagerly awaiting it’s release.

One of the first things that popped into my head when I saw what it was being called was that surely they could have picked a different cat since they used Leopard for 10.5, but upon thinking about it further, Snow Leopard is actually perfect for it, hopefully when I’m done, you will see why.

Apple says:

“Taking a break from adding new features, Snow Leopard — scheduled to ship in about a year — builds on Leopard’s enormous innovations by delivering a new generation of core software technologies that will streamline Mac OS X, enhance its performance, and set new standards for quality.”

So what’s the big fuss?

Microsoft Exchange Support

Well, one of the biggest things is full Microsoft Exchange support through Apple’s Mail, Address Book and iCal applications. As a user of Microsoft Exchange for my email, calendar and contacts on my desktop and Palm Treo 750, being able to sync my MacBook Pro with my Exchange Server would complete my work communications suite. I imagine there are plenty of other people in the same shoes as myself there, and I have no doubt that it is holding many people back that would otherwise be more interested in the Macintosh platform. Yes, there are other options available that I have talked about previously, such as using Kerio Mail Server instead of Microsoft Exchange Server. However, in a situation where Microsoft Exchange is already installed, this is not really a viable option.

I have noticed that Mail in Os X Leopard has an option to access an Exchange Server, but I have not tried this as of yet.

What else is there?

Open Compute Language

The other thing in Snow Leopard that is quite a big addition is what Apple is calling “OpenCL”, or Open Compute Language. I’m sure by now a lot of tech savvy people have come across the concept of using the processing power of graphics processing unit’s for general purpose processing as well as graphics processing. OpenCL is meant to allow development in this area. From the Apple website (server) (and personal), OpenCL is:

“Another powerful Snow Leopard technology, OpenCL (Open Computer Library), makes it possible for developers to efficiently tap the vast gigaflops of computing power currently locked up in the graphics processing unit (GPU). With GPUs approaching processing speeds of a trillion operations a second, they’re capable of considerably more than just drawing pictures. OpenCL takes that power and redirects it for use in high-performance computing applications like genomics, video encoding, signal processing, and simulations of physical and financial models.”

Grand Central and 64 Bit

Now, the other things listed on the personal, or client usage OS X site are not necessarily spectacular, such as mentioning 64 bit and multi-core support through Grand Central, seeing as how OS X has been 64 bit and with options running on multiple cores for years, but with all the confusion surrounding Vista and it’s 32 and 64 bit versions, it doesn’t hurt to re-establish that OS X is 64 bit and every computer is now running a multi-core CPU. What is interesting about these things though is the improvements Apple are making in the 64 bit field. With up to 16 terrabytes of RAM supported in Snow Leopard, is this paving the way for a new breed of Mac that could potentially run entirely from RAM rather than the slower hard drives? The MacBook Air has a solid state drive as an option, it would make sense to start offering them in other computers if the capacity can be brought to a sufficient level. With the vast amounts of power available in graphics processors and multi-core CPU’s (currently up to 8 cores and 4 GPU’s in Mac Pro’s), it makes sense that the biggest bottleneck is going to be the 7,200 rpm or 10,000 rpm hard drives.

Grand Central is meant to make the entirety of the operating system “multicore aware”, which I assume means that every part of OS X will be capable of efficient multi-threading, allowing them to run faster. I have seen it indicated and theorised in a few places, that Grand Central will be, or should be, providing a more efficient way of controlling multiple threads. This is particularly important as the more cores and threads you have running, the more overheads there are. So you can only add so many more cores before there is so much overhead that multiple cores simply won’t help. There is a good read about this over on ZDNet by Robin Harris. Providing a solution to this problem that is easily accessible by developers would be an excellent advance, regardless of what your preferred operating system is. If Apple hit it with Snow Leopard, it will have to push Microsoft to come up with a solution as well in time for Windows 7, if they don’t then there needs to be something else that can provide a significant performance boost on similar hardware.

I expect that in Snow Leopard, with the addition of OpenCL, that multi-core functionality on Mac’s will natively include GPU’s as well as CPU’s and processing across the two+ units as well as improving the 64 bit performance to potentially allow RAM to be used in place of hard drives. There are already solutions available that allow you to add RAM to riser cards that can be used as a small boot drive or swap drive, though they are very limited. It makes sense to extend this to allow maximum data access speeds for the processors.

What else is there?

Reduced Footprint

A reduced footprint is meant to be coming along. This is marketed as a reduction in the hard drive space used by the operating system, which grew in Leopard. This is always a nice thing seeing as how I like to have as much hard drive space as I can get my hands on, and I’m sure others will agree. However, the system footprint or a program footprint generally refers to how much RAM it utilises in order to run. Given the hints dropped in the 64 bit section relating to more free RAM, I hope that the reduced footprint will also reduce the amount of RAM used by the operating system, both when idling and under load. Though as it is, the RAM usage is nothing compared to Vista.

Compatibility

Unfortunately for those still using Mac’s based on the old IBM CPU’s, I have seen it mentioned in a few places that Snow Leopard will not be a universal release and the system requirements list an Intel-based Mac.

However, these system requirements are thus far only for the developers preview, so it may yet be available as a universal release.

No doubt there will be more than just what is being marketed at this stage, but thus far this is looking to be a very exciting release. What do you think?

I’ve had my new Sony Ericsson K850i which I bought on the $49 Maxi Cap account with Vodafone for a bit over a month, so I think now is the time to write up how I have found the phone, and how I have found the transition to Vodafone from Optus pre-paid. I’ll break this up into a couple of posts, this one being focussed on the phone.

It’s times like these that I am especially glad I have already upgraded my computer.

I have been re-rendering a bunch of fractals for print at 300 dpi on A0 and A2 sized paper. Even on the new computer, in order to get them done in time to have the high res images ready for printing for the exhibition I have had to cut the quality down compared to what I usually do them at. I’m looking at 15 hours on average for a fractal that is roughly half the quality of my normal renders, though once printed this won’t be so noticeable. This also results in around 3gb of RAM being used at any one time for the render. This is for A0. A2 I am averaging around 5 hours at half the quality with around 1 gb of RAM being used at any one time.

I’m not game to try and A0 on the old computer at all. I have had an A2 size one rendering though, it has an estimated render time of 40 hours at the same quality level as on the new computer, just so you have a comparison. I have also had to limit the RAM usage on the old computer since it only has 1gb of RAM. This means that instead of rendering the entire fractal, it will render it in 5 blocks which is slower, but it’s the only way I can do it on the old one.

Rendering A0 fractals on the new computer does render it virtually useless. While they on average use 3gb of the available RAM, they push the overall RAM usage up to an average of 98%, even when I close down the majority of things. Thus it is pretty pointless to even try to do anything else on it. Since I have limited the RAM usage on the old computer, it is still usable, but since I’m not rendering anything on the laptop, it doesn’t matter and I may as well let Apophysis have as much of the CPU time as possible.

While my laptop should do a reasonable job of rendering the fractals, since it is roughly half as powerful as Quadzilla (my Macbook Pro is a Core 2 Duo with 2gb of RAM, Quadzilla is a Core 2 Quad with 4gb of RAM), but I need the laptop to be usable all the time for uni and so on.

I would love to render all my fractals at these resolutions, but also at the quality I normally do them at. I’m thinking I’ll pick up another 4gb of RAM soon, though probably not for another fortnight or so since I have rent next weekend and the prints of these fractals are going to cost $56 each. If I get the extra RAM, that should make the computer usable whilst rendering, which means that it will be a lot easier for me to do them like this. Until then though, I could just limit the RAM usage to half and it should also be fine. I’ll just have to have a play around with it once these ones for the exhibition are done.

For those who have only seen my first fractal animation, the one I will be showing on Wednesday is a newer one that I did around September 2007. I also did the audio track for this one.

Who remembers my theories on how Apple are increasing their market share and becoming more and more of a threat to Microsoft and their massive market. Now a huge threat mind you, but it is still happening.

Well, the Oklahoma Christian University is now providing free Macbook’s to all their students, as well as an iPhone or iPod Touch. In addition to this, they are allowing students to exchange their Windows laptops for Macbook’s. Isn’t that awesome?

Just goes to show, changing an infrastructure completely to Mac’s is possible, and if one uni can do it, theres plenty of opportunity for others. It was only a week or so ago I was reading about another US university that was providing free iPhones to it’s new students.
