Apple – Double or Nothing?

Yesterday Apple announced another record quarter in sales.  In fact, iPhone sales doubled in Q4 2009 (a good holiday present for Apple).

Tomorrow Apples announces a new tablet computer (at least that’s the rumor of what they will announce).

Google has a lot of ground to catch up with Apple in the phone market, and it certainly doesn’t appear that Apple is going to just stand by and wait for them.

I guess the one thing that Apples numbers show is that there is money to be made in economic hard times if you’ve got something people want.

Amazon Merchants

Once again I’ve been disappointed with the “service” and “products” provided by an Amazon merchant.

I’ve ask Amazon how to inhibit the display of any and all items except those sold by them; I don’t care to deal with the questionable merchants that use Amazon’s sites.  And obviously Amazon doesn’t stand behind them either (look over their A-Z Guarantee, and notice that a person who buys an item every day has the same lifetime limits as one who rarely buys — sounds to me like Amazon is afraid to offer a real guarantee — why should I have more confidence).

Anyway, rather than play the game with Amazon I’ve just opened a charge dispute with my credit card company (which in this case happens to be an Amazon credit card).

If Amazon doesn’t have a way to block the display non-Amazon merchandise I’ll close my account (and credit card).

ASUSTek Computer Inc (Asus)

This is from one of my friends, send to Teresa Perdue ( tsd@asus.com.tw ) of ASUSTek Computer Inc ( http://www.asus.com.tw/ or http://usa.asus.com/ ).

I’d considered buying an Aus Eee PC… but I think I might be happier with a sub-notebook from one of their competitors.

I’ve removed the personally information (except for Teresa’s).

__________

Teresa,

Thank you for informing my that my motherboard is out of warranty and that you will not replace then fan.

In my opinion, this is not a warranty issue.  Warranties generally protect one from a product that happens to be bad.  Most reputable companies replace any item that is poorly designed or has an unusually high failure rate regardless of the warranty period.

I would like for you to know that I am very disappointed with Asus.  On your website you even say that the original fan did not work properly.
Also, there are numerous forums on the Internet that talk about the problem s with the AN8SLI chipset fan.

I have already had one Asus motherboard fail because of a chipset fan that failed.

I have probably built about 100 computers in the last ten years almost all of which used Asus motherboards.  It now seems that you are having quality control issues and that I will have to use a different brand of motherboard in the future.

I have just ordered two fans from your eStore.

Please understand that it is not the cost of the fans that is an issue.  My total charge, including shipping, is $22.00 which is insignificant.  What is significant is that I have learned that I cannot rely on Asus to replace faulty products.  I am unwilling to risk purchasing products from a company that doesn’t stand behind the quality of their workmanship.

This email is being copied to all of the other system builders with whom I work and will be copied to all system builder forums to which I belong.

Sincerely,

XXXX XXXXX

SFF-8484 to 4 x SATA Cables

I just purchased a Dell PERC 5/i (basically an LSI 8404) RAID card off eBay and I needed to purchase two SFF-8484 cables to connect it to my SATA hot swap bays.

There seems to be a great deal of confusion on eBay from vendors that have these cables — many of the vendors just don’t know what they have; and it’s important to know, since there are two different cables fitting the general description — and they are not interchangeable.

The cable I needed could be identified by a Trip Lite part number S502-01M or an Adaptec part number 2167000-R (discontinued) or a StarTech part number SAS84S450.

The description should contain the key phrase that the cable is used to attach a SAS (or SATA) HBA (Host Bus Adapter) to individual SATA drives.  The description should not mention anything about hooking up a SATA controller to a SATA/SAS back plane.

What’s the difference in the cables???

Well, the SAS controller to SATA device cable is straight through; the SATA controller to SAS back plane has the RX and TX swapped… and generally speaking there’s not a lot of call for the SATA controller to SAS back plane so those will be the least expensive, and the most prevalent on eBay.

The sellers who do know what they have, and advertise it as such want a phenomenal price for the cables (they’re only $19.99 on Amazon, buy the two you’ll need and they ship free)…

Do your home work and ask your questions before you commit to buy on eBay — particularly if it’s from China or Hong Kong (it’ll take several weeks to get the item, and returning it will be half the price you paid).  While Amazon’s gone down hill a great deal recently; it’s still easy to return, and in the long run you might save both time and money.

Hackers

I’ve noticed that here lately my SSH server has had an increasing number of hackers trying to log in.  Mostly they’re from the APNIC (Asia-Pacific) region, but a fair number from other regions (include North America) as well.

Since I have no plans to travel abroad in the near future I went ahead and blocked out all IP addresses registered through any registrar except ARIN, and I also added several hosting companies that seem to to have customers that either don’t secure their servers well or they themselves launch cyber attacks.

It’s generally a good idea to make sure that any server that can be used to gain entry to your network is as secure and limited as possible.  Obviously you don’t want to go overboard and make it impossible for you to do what you need with relative ease; but that said, you don’t want to make it easy for others to do things to your computers.

Disk Drive Temperature / Airflow

I upgraded both of my workstations (one Windows one Linux) to have a mirror pair as the secondary drive…  which added a third drive to each of the cases (the cases are setup so that you can have five 3.5″ internal drives and four 5.25″ external units)… the 400GB SATA-2 drive in the Windows machine keep producing SMART warnings that it was getting close to the recommended maximum temperature, and I decided it likely had to do with the fact that the power management of the motherboard slowed down the main case fan which reduced the airflow.

The case actually had two cutouts for fans in front of the disk drive array, so I wired up a couple fans for each one off a single power connector, put the fans in and now the drives are running cooler (the 3TB SATA-3 drives in the mirror in the Windows machine are much newer drives and run much cooler).

Keep in mind, that the cooler your drives run, the longer they’ll probably last and the fewer problems you’re going to have — plus when you run drives close to their maximum recommended temperature you’re going to see thermal re-calibrations which are going to make your computer look like it’s hanging or at least stuttering.

While I don’t think you should get crazy with fans, you should insure that any location in the case that has a heat producing component should have airflow — and many fans come with speed adjustments so you can run them at their lowest setting and provide enough airflow while minimizing the fan noise (which can be deafening if you have lots of fans).

One last thing — make sure when you buy fans you buy good quality ball-bearing fans — if you don’t, you’re just wasting money and asking for a fan failure (plus way too much noise).

Grasping at nothing with billions

Intel paid 7.7 billion dollars (US) for McAfee Associates.

WTF is up with Paul Otellini?

Does he really think that having pathetically outdated security technology is going to help keep Intel in control of computing in the ever changing landscape of mobile computing?

Clearly Intel must be in the dark about how modern software is built from the ground up to resist the security issues that plagues the old cobbled together systems of the past (ie Windoze).  Obviously, though, Intel understands that their dominance in the computing arena is likely to fade — but spending this kind of money is just insane.

One thing is clear — Intel is massively over charging for it’s processors if they can afford to dump nearly $8B US into the trash can.

Computer Cables

Whether you have a Windows PC, a Mac, or a *nix box, the one thing you’ll have a headache with is all the cables.

And for those of you who try to say you don’t — all I’ve got to say in The Nile ain’t just a river in Egypt!

There are all kind of products sold on the market to manage the cables on your computer, and many of them will make it look better, but most of them just make it that much harder to do anything with them — so if you’ve got an Architectural Digest shoot coming up you might want to run out and buy one of those, but for those of you who just want to get a handle on the cables I’ve found something that might help.

What I’ve started doing is taking a couple (sometimes three) Velcro ties and bundling all the cables that come out of the back of the computer for about a foot to a foot and a half… what that does is it keeps them together and out of the way for sliding the computer back and forth, but doesn’t create a nightmare every time you need to do something.

You want to make sure that you allow all the cables to gently bend into the bundle (not sharp kinks — it’s just not good for the cables of the connectors), and make sure that there’s reasonable clearance behind the computer (if not, you can bend the bundle to one side).

The Velcro ties are fairly inexpensive, and you can get them at office stores, dollar stores, etc.

Virtualization Solutions

On windows there’s basically three commercial solutions for virtualization, and several free solutions… wait one of the commercial solutions is free (well when you buy the operating system), and the other is partially free…

  • Microsoft Virtual PC (runs on both servers and workstations)
  • Microsoft Virtual Server (runs on both servers and workstations)
  • Microsoft Hyper-V (runs only one Windows Server 2008)
  • Parallels Workstation (runs on workstations)
  • Parallels Server (runs on both servers and workstations)
  • VMware Player (runs on both servers and workstations)
  • VMware Workstation (runs on both servers and workstations)
  • VMware Server (runs on both servers and workstations)
  • Citrix (aka XenSource)

For Intel based Mac you have commercial solutions

  • Parallels Desktop
  • Parallels Server
  • VMware Fusion

And for Linux you have the following commercial solutions, and many free solutions (Xen being one of the leaders)

  • Parallels Desktop
  • Parallels Server
  • VMware Player
  • VMware Workstation
  • VMware Server
  • Citrix (aka XenSource)

And for bare metal you have

  • Parallels Server
  • VMware

 

I’m not going to go into details on any of these, I just wanted to give at least a partial list with a few thoughts.

If you’re new to virtualization, use one of the free virtualization solutions.  You can try several of them, and many of them can convert a virtual machine from another vendor’s format to it’s own, but learn what the strengths and weaknesses are of each before you spend money on a solution that might not be the best for you.

Microsoft Virtual Server has some definite performance advantages over Microsoft Virtual PC… there are some things you might lose with Virtual Server that you might want (the local interface); but Virtual Server installs on both desktop and workstation platforms, so try it.

For Mac I definitely like Parallels Desktop better than VMware Fusion; but you may not share my opinion.  VMware claims to be faster, though I certainly don’t see it.  And I might add, that if you have a decent machine you’re running virtualization software on, fast isn’t going to be the number one concern — correctness is far more important.

Also, with each of the virtualization systems, hosts, and guests there are best practices for optimizing the installation and performance.  I’ll try and write up some information I’ve put together that keep my virtual machines running well.

For the record, I run Microsoft Virtual Server 2005 R2 (64 bit) on Windows Server 2003 R2 x64 SP2, and on Windows Vista Ultimate and Business x64 SP1; works well.  And I run Parallels Desktop v3 on my Macs.

For the most part my guests are Windows XP Pro (x86) and Windows Server 2003 (x86); I don’t really need 64-bit guests (at the moment), but I do also run Ubuntu, Debian, Red Hat, Free Spire, etc linux…

Like I said, figure out your requirements, play with several of the virtualization systems and spend your money on more memory, perhaps a better processor, and stick with the free virtualization software!

Xoom

Several weeks ago I purchased a Motorola Xoom (WiFi only model), I’d looked at the Acer, the Asus, the Samsung, and read up on the Thrive — I decided that the Xoom was the best candidate of the available Android/Honeycomb tablets available now.

I’m happy with my purchase, and it’s amazing how quickly a “gadget” can find its way into your everyday life.

I will write a lengthy review of the Xoom to let you know everything I like about it, and the things I really don’t think are that great… plus I’ll write a post on my rooting adventure (after all, it’s Android, why wouldn’t you root it).

Let me just close with it’s a great tool, and if you’re willing to carry something like that with you it gives you incredible access to books, news, entertainment, information…

I do expect that prices for 10″ tablets will continue to come down… but I’d definitely recommend you only consider a dual-core (or better) tablet.
