"Why would anyone buy a Mac now?"

There was a bit of a lively discussion the other night about Macs and PCs. A friend had picked up an Acer Laptop for about $350 with a pretty impressive spec sheet (15" monitor, dual-core processor, 4 GB RAM, 256 MB graphics card, Windows 7). He had looked into Macs but the closest thing to that was the MacBook Pro 15" for $1600. Ouch, what a price difference!

Then he poses the question: "Why would anybody buy a Mac now?"

Hmm. Well, I can't imagine he came to me looking for objectivity, I'm fairly well biased. Still, are we really that disparate now? A $1250 premium for a Mac laptop does seem pretty onerous, especially since Macs and PCs were supposedly on par pricewise for awhile there.

We should probably mention here that at least some of that cost savings on those PC laptops is advertising -- apparently companies pay PC manufacturers to include their software on the machine. So when you boot it up, you get a ton of ads, spyware, and other junk you have to turn around and clean back off. What a mess. I'd pay $100 just to not have to mess with that. So we're up to $450, but that's a far cry from $1600.

So what'd I say to him?

I told him different people value things differently, and I could think of at least 25 things I valued enough more on the Mac to make it worth it for me.

"No way!" he says. "You can't think of 25 things."

Easy:

  1. No viruses. What is that peace of mind worth?

  2. Awesome process scheduler. The mac prioritizes the user interface much better than Windows. Doesn't seem to matter how busy the computer is, I can still move the mouse around, switch windows, etc. Windows (and linux for that matter) have always let the interface suffer when the machine gets busy.

  3. Window manager not in the kernel. Huh? This means that the part of the OS that draws the windows is wedged into the core of the OS, but runs as a separate process. Why is this good? Ever have your Windows-windows stall, i.e. stop drawing? You drag them and they act like a cutout of that part of the screen? Happens all the time on Windows, but rarely on the Mac (actually never, but I hesitate to use that word).

  4. Time Machine. Plug in a spare drive, accept the OS's offer to make it a Time Machine drive, and it builds you a back up, taking regular snapshots as incremental backups (but not wasting drive space!). Their solution is quite elegant (uses unix hard links), each snapshot looks and acts like your entire disk file structure. Very nice!

  5. Spotlight. Fast system-wide contextual search. Maybe Windows 7 does this better, but none of the Windows versions I've ever used have done this well.

  6. Expose/Spaces. Supposedly Windows 7 just stole this from the Mac, but I'm guessing they did a half-keister job of it. I love being able to invoke expose or spaces in the middle of a drag.

  7. Unix. The Mac is a unix machine under the hood, and it's very nice. I have written lots of perl and awk scripts to do stuff for me, and it's great being able to have perl create emails for Entourage (Mac equivalent of Outlook), or to pipe the output of a unix command to my text editor. Also has X11, so much of the open-source stuff from the linux community is available as well. I love rsync. Love that I can type "open ." in a terminal window and have the Finder open a window of that subdirectory; or drag a file from the Finder into a Terminal window and have it insert the path to that file. SSH/sshd built in. Find. Apache webserver. Super stable. Etc.

  8. Robust networking. I come and go on my laptops, and they always just happily connect to the network wherever I am, wired or wireless. I could never get Windows to do this.

  9. Column view in the Finder. I've grown to love this view. The sidebar shortcuts are also a huge time saver.

  10. Long battery life. My work laptop gets 5-6 hours off a single battery charge. My home laptop is older, but usually gets 2-3. I was lucky to get 45 minutes out of my Windows laptop.

  11. Built-in PDF generation, editing. Anything you can print in the OS you can make a PDF of. I use this *all the time*. Also, you can delete and reorder pages, then save a copy. All built-in.

  12. No reboots necessary. I seriously can't remember the last time I restarted either my work or home laptops. I put off OS updates just because I don't want to have to reboot. I love an OS with long-term stability!

  13. Good sleepers. I just close the lid, and when I open the lid, they're back up and usable faster than I can get the lid opened all the way. My Windows laptop would always drain the battery whenever I just closed the lid, and the machine would be off the next morning when I opened it back up. I wanted to drop-kick it into the parking lot. On the Mac, when the battery's about to die it writes the contents of RAM to the hard disk, and when you power up it reloads the RAM in about 10 seconds and you're back in business. Awesome.

  14. Multi-touch trackpad. Windows laptop trackpad stunk -- no multi-touch, inconsistent response, etc. Mac laptop is a joy -- 2 finger scrolling, 3 finger page turns, 4 finger expose control, and more.

  15. Quick window zoom. Hold down control and swipe 2 fingers up or down on the trackpad (or hold down control and spin the mouse wheel). Fun, and I use it all the time.

  16. Best of 2 worlds. A platform with native MS Office, Photoshop, Quicktime, and unix terminal all in one. Any other platforms do that? I can also run Windows and Linux in a virtual machine, having all 3 platforms on one machine.

  17. Great keyboards. I love the new flat keyboards, they have a nice touch.

  18. Auto detect monitors. Everybody at work who plugs their Windows laptop into a projector or external monitor has come to expect trouble. Not me, monitors come up fine, even hot-plugged.

  19. iChat with screen sharing. If mom calls needing help with her computer, I can be looking at and controlling her screen in about 20 seconds, all with built-in software. Awesome. Pretty rare, though, she doesn't need help very often.

  20. One-click flash drive eject. Why does Windows make this so hard? Snow Leopard made ejecting flash drives a joy, no more "you can't eject this drive because an application is using it..." errors.

  21. Built-in screenshots. I can take a snapshot of any part of my screen with a single keystroke, very cool.

  22. Built-in zip and unzip. No WinZip necessary. I prefer tarballs myself, and also has bzip2.

  23. Built-in dictionary/thesaurus. I use this all the time. You can even do a spotlight search for a word and one of the options is the definition in the Dictionary app.

  24. Applescript. System-wide almost user-friendly scripting tool. Lets you do things like automatically build a spreadsheet from the contents of an email filtered through a unix command, then email it to someone, all automatically. Does require some skill but not a CS degree.

  25. Quicklook. Highlight any file (or files) in the Finder and press space and get an instant preview of it. Another huge timesaver.

  26. Mounts and compatibility. NFS, SMB, AFP, FTP, VNC connections supported natively (probably more). Macs can read FAT32/NTFS drives, but PCs can't read Mac HFS+ drives.

  27. Disk images. Built-in support for encrypted and non-encrypted drive images. I store all my sensitive stuff on one of these and don't worry about my laptop getting stolen.

  28. Acceleration sensors. Laptops have acceleration sensors such that if it detects that it's falling, it quickly parks the drive heads on my hard disk before it hits the ground to keep from damaging my drive.

  29. Drivers. Almost no futzing with drivers. With my current batch of hardware I didn't have to install goofy drivers for any of it, not my printer, scanner, digital camera, or digital video camera. Ever try installing a printer under Windows? Never works the first try, often not the second either.

  30. Unobtrusive. Somehow on PCs I feel like I'm always tripping over the interface, it's always asking me dumb questions or notifying me of things I don't care about. Or not working for reasons I can't determine (and my Windows using friends can't either). The Mac works, and stays out of my way and lets me work.

There's 30, want me to keep going? =)

A little bragging...

Can I just take a timeout from my usual blogging fare and brag about my wife for a minute?

Kyla and her running partner Kathy after their last race


Yesterday morning she ran a half-marathon. Yes, a real half marathon. Just over 13 miles in just over 2 hours. How cool is that? To be able to just start running and keep going for a couple of hours, now that's just incredible to me. She wasn't even sore afterward. Awesome.

Way to go, babe!

Go To The Source

Joseph Smith:
Search the scriptures-search . . . and ask your Heavenly Father, in the name of His Son Jesus Christ, to manifest the truth unto you; . . . you will then know for yourselves and not for another. You will not then be dependent on man for the knowledge of God; nor will there be any room for speculation. - Teachings of the Prophet Joseph Smith, pp 11-12


Brigham Young:
I have uniformly exhorted the people to obtain this living witness each for themselves; then no man on earth can lead them astray. - Journal of Discourses, 6:100


John 16:13:
Howbeit when he, the Spirit of truth, is come, he will guide you into all truth...


Matt. 7:7-11:
Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you: For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened.

Or what man is there of you, whom if his son ask bread, will he give him a stone? Or if he ask a fish, will he give him a serpent? If ye then, being evil, know how to give good gifts unto your children, how much more shall your Father which is in heaven give good things to them that ask him?


I love it that when it comes to religious things, we don't have to take anyone's word for it.

Scale in biology

Ever wonder how big a red blood cell is compared to the flu virus? Or a single chromosome compared to an atom?

This is the coolest thing I've seen all week.

Healthcare Costs

I never paid much attention to my medical plan at work, until a few weeks ago when people started complaining about healthcare premiums being higher in AL. I hadn't noticed.

So when my benefits-selection stuff showed up, I decided to do a little research on the plan I had selected.

Check this out:















YearMy healthplan cost as a percentage of my salary (gross)
20011.4%
20021.5%
20031.7%
20041.9%
20052.2%
20063.0%
20073.1%
20083.5%
2008
(move to AL)
3.9%
20093.9%
(good raise)
20104.2%
(also good raise, but not good enough!)



Can you believe how fast this is climbing? And this is adjusted for my salary!

Surely there are better alternatives, especially for people like us who aren't getting as much as we're paying.

One idea is to just save the many thousands of dollars we're putting into health-plan premiums, pay cash for whatever services we need, and if someone needs a major operation, get it done in New Delhi or Costa Rica.

I have no confidence that Congress will come up with a healthcare plan that works on purpose. But they might get lucky...

Whose fish?


Not a Walleye Pike


Yesterday I ran across a puzzle on Coudal.com, supposedly created by Albert Einstein and accompanied by the assertion that only 2% of people can solve. Looked like fun so I tried it.

In case that link ever goes down, here are the clues:
There are five houses in a row in different colors. In each house lives a person with a different nationality. The five owners drink a different drink, smoke a different brand of cigar and keep a different pet, one of which is a Walleye Pike.

The question is-- who owns the fish?

Hints:
  1. The Brit lives in the red house.

  2. The Swede keeps dogs as pets.

  3. The Dane drinks tea.

  4. The green house is on the left of the white house.

  5. The green house owner drinks coffee.

  6. The person who smokes Pall Malls keeps birds.

  7. The owner of the yellow house smokes Dunhills.

  8. The man living in the house right in the center drinks milk.

  9. The man who smokes Blends lives next to the one who keeps cats.

  10. The Norwegian lives in the first house.

  11. The man who keeps horses lives next to the one who smokes Dunhills.

  12. The owner who smokes Bluemasters drinks beer.

  13. The German smokes Princes.

  14. The Norwegian lives next to the blue house.

  15. The man who smokes Blends has a neighbor who drinks water.


There are no tricks, pure logic will get you the correct answer. And yes, there is enough information to arrive at the one and only correct answer.


There are a couple of references on ways to solve this on Coudal's website, but none of them seemed very good to me. I solved the whole thing in only 15 minutes or so, and their approaches looked hard. So, once you've got the answer, check out my approach here. If your way is better, put it in the comments, I'd love to see it.

Good luck!

Malware on the Mac

I've said it before, but after this story from Computerworld, I'll say it again: your Mac can't stop you from downloading and running malware*. This time it's video codecs from Russian websites. "For helping you play diss videos our vebsite, download diss program and it help you."

These days, as long as the website looks reputable you're pretty much okay. That may not be the case forever, though, so make sure you're being careful. "But hey, how am I supposed to know what a reputable web site looks like?!" Here are the websites for a few of my favorite Mac apps: Firefox, Keyboard Maestro, MarsEdit, CSSEdit, Transmit, 1Password, BBEdit, Delicious Library, Google Earth, MacTracker, and Adobe Photoshop.

Caveat websurfer.


* "Malware" is not a virus. Viruses self replicate, often without the user even knowing. Viruses are rampant on Windows. Malware, on the other hand, is a program that does bad stuff that the user installs willfully, usually because the they think it's a game or free software.

Does anyone read this thing?
