Time Machine

Looks like Apple's "Time Machine" feature can be made to work with a non-Apple fileserver. From the helpful hint at the following URL, I now have it working to my fileserver, a FreeBSD machine with netatalk... http://blog.danielparnell.com/?p=43
Now... I just need some more storage space...

Leopard is a bit spotty

It appears that the formerly excellent X11 support in Tiger has regressed and the X11 support in Leopard, despite being based upon the more modern Xorg codebase, shows significant regression in functionality.
  1. Unable to move windows on to secondary displays

  2. Unable to be configured to use TCP connections, except by manual startup (Do we really need multiple Xquartz processes?)

  3. DPI is fubar - I prefer to set 75DPI even though I have large displays - I have large displays because I want more stuff on the screen!

  4. Display feels slower.

Some of the other new features are nice - the new SSH AskPasswd program is a nice new touch but I think I shall just have to bite the bullet and 'upgrade' to the Tiger X11 release. I shall be following the instructions detailed at http://aaroniba.net/articles/x11-leopard.html

Leopard's CUPS defaults

Mac OS 10.5 was not discovering my CUPS printers like how 10.4 was. It turns out that Apple has decided to only discover printers by Bonjour only and has turned off CUPS own detection. This seems like a poor decision.
I found the answer at http://mcdevzone.com/2007/10/28/printer-fix-for-leopard

Leopard Review

Here is my not-very-objective review of MacOS 10.5 aka Leopard.
Installation was pretty painless - I uninstalled things like APE beforehand and after reading the various blogs where people had hanging installs, I am sure glad that I did take the precaution. It feels faster on my Quad-G5 PowerMac - things seem to respond faster. Visually - I'm going to have to change the default background - some of the annoying artifacts on the menu bar are from the background image. The work done to Mail - is excellent. Much improved responsiveness. The iChat improvements are very welcome - it can now be signed-in on multiple accounts.
I have not managed to get Time Machine working from using a FreeBSD fileserver, even when I have netatalk installed and operational - There has been some skectchy reports of workarounds but its not working here. I really don't want to have an external drive for each Mac for backup - I would prefer to be able to back them up centrally over the network.
With respect to software development - time will tell. There is already some indication that the assembler/linker may have some problems with some inline PowerPC assembler which prevents the build of the glib macport from completing successfully.

Mac OS X Leopard has arrived

Actually, the small box arrived about an hour ago. Clearing some old work source repositories from my hard drive and other general 'housekeeping' duties. I haven't eagerly anticipated a new OS release for a long time: I would probably compare this to the time when OS/2 2.1 was released with its full 32bit Presentation Manager or perhaps even OS/2 Warp 3 with its UI enhancements... As to what features I am looking forward to exploiting, I would say in no particular order: Spaces, XCode, DTrace, Shark. There is a bunch of other 'nice to have' features... I guess I will see how well I like it after I install it.

We can smell the smoke from here.

All throughout today and yesterday, there has been ash falling from the sky from all the fires around near Los Angeles. We have had all the windows closed to keep the dust and ash out - going outside for a short while irritates my eyes something awful and that is even though I take a powerful anti-allergy medicine daily.

Today we lean that Microsoft has lost it's appeal regarding their monopolistic practices in Europe. I foretell that Microsoft will continue with business as usual and otherwise completely disregard the ruling and the penalties. So, they may pay the fiscal part of the penalties but the rest of it will have to wait for Satan to get a new job as a snow-plough driver in hell.
What can be done about it? Quite simple. It is within the EU's power to void Microsoft's copyrights, patents, trademarks and all other intellectual property in Europe.
Radical, yes. But it would also serve as a warning for all other companies that they are not above the law. Europe is a big market for Microsoft ... bigger than their American market.
I doubt that would ever happen but it doesn't hurt to dream.

Time to morn the passing of an old friend. My old Pentium 200MMX (SMP 2 Processor) machine would not start up today. The PSU is fine - the DPT SCSI controller can be heard to spin up the hard drives but to no avail - the CPUs failed to start up. No POST beep codes, nothing. No activity.

*sighs*

It was a trusty workhorse, from 1997 to 2007.

Only one question plagues me.... What machine should I butcher in order to have a working OS/2 machine or do I wait until eComStation goes GA and buy a modern machine?

06 September 2007

I am not happy. As to why I am not happy, lets consider a hypothetical situation: Imagine you have purchased a new computer and while it was in warranty, it kept crashing and working slow. The manufacturer of the computer thinks that the CPU may be a little faulty so they want you, the end user, to take out the CPU and ship it to Intel for diagnostics. And while you are at it, maybe you should send the video card to Nvidia, just in case.
Would you accept that kind of situation? I doubt it. You purchased the computer whole and complete from one vendor, you do not expect to go to the suppliers of the computer's vendor in order to have it fixed. You'd think it to be unacceptable... What if there was a faulty diode on the motherboard... Would your PC vendor expect you to go to IR for a replacement diode?
Ugh!

Anyways.... Our car has been having problems. It isn't even two years old yet but it has already spent about two months sitting at a Saturn dealership. It has had 3 steering columns replaced. 2 drive wheel bearings. a transmission control modules and an engine management module ... and thats only the expensive parts. Now, we have had the driver's side front drive tyre blow out two times in as many months: Both times, the tyre failed in an identical fashion. Now we (the end user) must send the tyre to the manufacturer to be examined for defects... The first tyre came with the vehicle, the second was purchased from a Saturn dealer.. ie. Both failed tyres came to us via Saturn. WHY DO WE HAVE TO TAKE THE TYRE TO THE MANUFACTURER? Absolutely non-existent customer service: They should be bending over backwards for us, especially when you consider the entire catalogue of faults that this vehicle has had to date.

I am not a happy Saturn customer.
I cannot in good consciousness recommend anyone else to buy a Saturn vehicle.

I wish I had purchased a Volkswagen.

Something seems a bit fishy in Redmond Land.... As many people who know me know, I don't use Windows that often but I do mostly for my work and I'm typically using Visual Studio C++. Only yesterday, I fired up Windows XP and after a couple of hours of use, up popped up the dialog for installing updates. I simply closed what I was doing and let the updates occur.
Windows XP rebooted and I began to use it but when I copied files over the network, I had a nagging feeling that the performance wasn't quite up to par.
Today, I have tried transferring larger files and I notice that it appears to stall frequently while performing the file transfer. So I started "ping -t" ... and wouldn't you know, this machine which used to have no problems is now dropping about 1 in 10 packets over my fully switched network. Just in case it was a faulty port on the switch, I changed the port and ethernet cable. No change.
Is this some sinister plot to make Vista "better" by crippling older XP installations?
In any case, it is stupid - and dropping that many packets causes a lot of problems. I cannot believe that everyone are experiencing this or else there would be a worldwide outcry - a revolt. Perhaps its just a coincidence that the network card is now faulty but it's a bit awkward to resolve as the NIC is the on-board integrated port on a laptop. I guess I will have to try with a PC Card device and see if that rectifies it.

I was wondering around a superstore the other evening when the black Windows Vista box caught my eye... It says there, right under where "Windows Vista Ultimate" is written, "The most complete Windows ever" or something like that.
What I would like to know is.... Why would anyone want an incomplete operating system? I don't care if it is the "most complete". I want an operating system which is "complete".
Still, I have to admit that the most expensive software purchases I have personally paid for in the past couple of years has been 2 retail boxes of Windows XP Professional. Of all the people I know personally who have tried Windows Vista (usually bundled with their computers), almost all of them have either purchased Windows XP or have somehow acquired a DVD. One person even considers installing XP Home an upgrade over the bundled Vista Home Premium. For all of Windows XP's flaws, it never drove people to install Windows ME. I have to confess that I haven't actually used Vista long enough to be as frustrated with it as those people but to be perfectly frank, Windows XP Pro does everything I need out of an OS when I need to use it.
There are a few new pieces of software which I will purchase in the near future when they are released: Mac OS 10.5 which I will probably buy the family pack and the expensive one: eComStation 2.0 - partly for nostalgia's sake but I also have a unopened, still in shrink wrap, Hopkins FBI for OS/2 which I have been thinking about trying for the past couple of years.

It looks like Kingston Technology is serious about their Lifetime Warranty on their products. A little under a week has passed since I had sent them the memory which had gone faulty - and it didn't cost me a penny. They paid for the FedEx shipping both ways. The replacement module looks a little different than the returned and the new modules I had purchased immediately after the failure: They all had identical track layout unlike the replacements. It all seems to work though. The machine has correctly identified the modules and so now it has 4.5G RAM.
On a little side note - I tried to post this message earlier today but the Google Blogger site appeared to be down for maintenance.

07 August 2007

Yay, the new memory arrived. I am glad that I didn't splash out and only paid for the standard delivery - it arrived next day. The machine was getting a little slow without the memory even with a lighter workload than normal - the swap had grown to 1.5Gb after a day's use. I still need to get a RMA for the old memory so I can send it back for replacement...

05 August 2007

Oh Joy.... The past few days, my Mac started crashing randomly, usually just applications or a MySQL test run would show that the server SIGSEGV. Quite annoying. Today, it locked up complely. Not even the mouse cursor could move and it didn't even show the MacOS kernel panic message. So enough was enough. I found the MacOS install CD and started the Apple Hardware Test. Kicked off the extended test and wandered away to do other stuff. When I came back, I was greeted with a message that the memory was faulty:

2MEM/1/4:DIMM3/J7000

It's well beyond the Fry's 30day replacement but definitely less than a year... so I will have to call Kingston on Monday for a RMA number for it. Meanwhile, I'll order some replacement memory so that the machine won't be crippled for too long... besides which, when the replacement memory comes back, I will have a bit more memory to do stuff with.

05 July 2007

Yay! The new motherboard, CPU, RAM and PSU are npw installed into my home fileserver. Booting up and running straight after the major upgrade without a hitch, very nice how seamless FreeBSD makes the transition but there again, I expected that to be problem free. Sitting on my desk is the old motherboard, an Intel OR840 with a Pentium 3 800MHz processor: A real oddity by todays standards as the CPU is a Slot-A module and the RAM is RamBus 800 modules. There is a spare slot for a second CPU which is only populated by the termination card... as are half the RAM slots. Tempting to try to find a second CPU and perhaps I will splurge and buy eComStation to run on this odd motherboard. At least now, I will be able to update FreeBSD on the fileserver without worrying about carefully reapplying patches to allow FreeBSD to work without problems on the OR840.

03 July 2007

Just when I was somewhat enthusiastic about swapping over my fileserver motherboard, I discover that my power supply is too ancient to support the new motherboard. Ho hum. So I have ordered a new PSU and it should arrive on the 5th. I was hoping to be able to do the swap during a day-off so theres minimal interruption.

28 June 2007

Server upgrade imminent. I have purchased a new motherboard, CPU and RAM to replace the aging Pentium 3 + OR840 combo with 128MB RamBus RAM I am currently using in the server. The new motherboard is a SuperMicro PDSGE and will have a Pentium 4 650 and 1Gb of RAM. I am probably not going to use the new motherboard's on-board gigabit ethernet adaptor because of concerns about Intel's AMT technologies.... Heck, I may just place the AMD PC/Net PCI adaptor for the outward facing interface (Yes, that is the same adaptor I 'cloned' when I wrote my AMD PC/Net PCI emulation for QEmu which is incidentially also used by Xen when performing machine emulation). I may just use the on-board gigabit NIC for a direct crossover link to the Mac for fast jumbo frames. Meanwhile, I just have to make sure that I have everything - Likely to need a new PSU to power the motherboard. Will probably need a few new case fan, good practice to replace them anyways for a machine which practically stays on 24 hours a day.

13 June 2007

Every now and again, I have to have a large sigh...


*** sighs ***


With the recent release from Perdue detailing a computer simulation of the 9/11 WTC attack, the fierce debates that it spawns as to the "It's an inside job" vs. "No it's not," camps and their arguments miss the point of the simulation.
I have looked at the short video clip and I would say that it seems plausible: I could imagine a aeroplane causing that kind of damage. It is also clear to me that the damage rendered to the core columns is inadequate to cause a complete structural failure of the whole building, especially considering that the aeroplanes hit quite high up on the building. There was relatively little load being supported by the core columns at that level.
Of course, the "Terrorists hate us" camp would trot out the argument that steel only needs to be heated up to half it's melting temperature in order to begin to warp and fail. Given that the buildings were hit some 400m above ground level, assuming that there was enough fuel burning to heat the core columns via radiation, and assuming that 100% of the radiation was absorbed with no radiative losses... for that heat to propagate down the core columns such that all the columns were heated sufficiently that a cascade "pancake" collapse would occur, hmm... after some scribblings on a back of a napkin.... assuming a rather light core column at an average cross section of .34 sq m per column... it would take as much energy as released in 18 million pounds of TNT to raise all the core columns to 800 degrees Celsius... Or expressed as a speed of a 747 aeroplane if translated into kinetic energy - about the same as if it was traveling at around 10,000 miles per hour.

Pretty fast, innit?

Oh well... People never let facts bother their perception of the world. Unfortunately, they let any idiot vote nowadays.

This is amusing... Ok, perhaps ironic, also prophetic... But quite definitely amusing.

Delayed posting, originally for Monday 16 April, 2007

So much has happened during th past week but due to the happenings, I have not been able to post any news.
Easter Sunday at around 3:30am, my mother in law suffered a severe heart attack. She passed away early on Tuesday at about 4:30am. These events were completly unexpected due to the full exam she had a month ago and of her mere hours before the heart attack. We held her funeral and burial on Friday. There was quite a good turnout.
