  • Viewing HD Video on the Web

    You may have found that Internet videos sometimes don’t play cleanly –  that is, they start and stop and stutter. I’m going to talk about how to fix that problem.

    When you watch a video “on the Internet”, what’s actually happening is that the video has to be downloaded to your computer before viewing. Don’t worry, Windows (or Mac or Android or whatever) will discard the video file after you’re done; you don’t have to do anything.

    When you start the video, you’ll see at the bottom left a little “progress bar”. The number is the time into the video; the little green bar shows how much video has been downloaded. As long as the green bar is ahead (to the right) of the time, the video will play smoothly. The best strategy is to wait for the green bar to get at least half way before playing; otherwise you’ll probably experience some “stuttering” where the video stops and starts over and over.

    Another tip for enjoying HD video is to make the video “Full Screen” – to do this, click the little icon in the lower RH corner:

    Smugmugfullscreenbutton

    This will expand the video to full screen on your PC. Don’t worry, to switch back, you press the “Esc” key on your computer keyboard.

    Happy Viewing!


  • Things that go fast – Laptop Edition – Round Two

    A couple years ago, I wrote about upgrading my laptop from an HDD to an SSD. The change in performance was awesome, but the longevity of that particular SSD – not so much. Long story short, the SSD bricked, I went through the replacement process, then discovered that software encryption does not work on an SSD. There’s a technical explanation for this if you care to go down that particular rabbit hole.

    I have a self-imposed requirement of full encryption on any laptop I travel with –  two words: “identity theft”. The issue at hand is that if your laptop is stolen, even assuming you have Windows passwords, etc., it’s a pretty simple matter to pull the drive out, mount it and read all the data on it. Unacceptable.

    Before moving on to the result of the new SSD upgrade, I’ll spend a few words on “Why you would care” (above and beyond the onboard encryption)…

    Computer Subsystems

    The picture above shows the major subsystems of a computer –  PC / Mac / iPhone, supercomputer, whatever, all have rough equivalents.

    • CPU –  the brains of the outfit; where all the thinking goes on.
    • Memory –  AKA RAM, AKA fast and expensive, this is where the information needed for the things you are working on or looking at right now (like on your desktop) is stored. Important point –  the information in RAM disappears when the computer is turned off. That’s why you’re prompted to “save work” when you’re shutting down or restarting your computer.
    • Video Card –  processes the information needed to change what you’re looking at on a computer screen.
    • Hard Disk –  the computer equivalent of a file cabinet or library. Information that you need kept for the long term is stored here. I’ll insert an editorial comment here  –  if there’s information (pictures, videos, spreadsheets, letters, etc) that is really important to you, you’ll have a backup copy of that information in some safe place.
    • Motherboard –  ties everything together and provides lines of communication between the subsystems, including, but not shown, your mouse / touchpad / keyboard.

    All of these subsystem components are currently running at speeds such that individual events happen in a range of .000000001 second or less – except the hard drive, where things happen in the .001 second range – in other words, the hard disk is the horse and buggy at the Indy car race. An SSD, being fully electronic, gets long term storage back in the race.

    OK, lots of technical verbiage –  here are a list of things that will happen much faster on an SSD system vs an HDD system:

    • “Boot” time –  from when you turn your computer on until it’s ready for you do something. On my laptop, this went from over a minute down to 21 seconds.
    • Installing a program
    • Launching a program
    • Tagging pictures
    • Editing videos
    • Backing up your hard drive

    Bottom line –  your computer will ‘feel’ far faster overall in every circumstance that involves the drive.

    Back to the upgrade –  two things have happened since a couple years ago –  1) Intel produced a secure solution, and 2) I’m home with time to mess with a laptop.

    I installed the new Intel SSD, did a clean Windows 7 install (from a thumb drive, what an improvement that is!), and set up the BIOS HDD password. Then I downloaded 64–bit benchmarking software from PassMark and ran the tests on the old system (HDD) and the new system (SSD). The  resulting awesomeness in chart form:

    Graph

     

     

     

     

     

     

     

     

     

     

     

     

     

    The most important number to you is the ‘Random R/W’ number –  a more than 50 times improvement. At first I thought “there must be some mistake” –  until I remembered that the HDD is the equivalent of buggy-whip technology in a computer. HDD technology was invented in the early 1950’s, and although optimized to the nth degree by the subsequent 60 years of development, still remains dependent on rotating disks and moving arms –  and mechanical things cannot physically move at the speeds of electronic circuitry.

    Armed with that, plus a little cross-referencing on other testers’ results, and –  I’m good with that number.

    Bottom line –  the single biggest change in performance for that aging laptop or desktop system might well be to get rid of that HDD and replace it with an SSD –  and if you also require the security of drive encryption, at least consider the Intel 320 series.

    Namaste, Rick

    P.S. –  if you happen to be thinking about a new laptop, be sure to consider the new Ultrabooks, a little competion for the MacBook Air…

    P.P.S. –  this my first blog entry edited entirely offline. MUCH more pleasurable. Thanks, Amy!!!

  • Panorama Mania

    Carol and I like the wide open places. Places like the tops of mountains where you can see the curvature of the earth. We also like to share our experiences through our photography – guess you might call us “serious amateur photographers”.  It’s somewhat impossible to do justice to the big places with single snapshots; combining multiple photos into panoramas can work.

    I often have discussions with friends and family about cameras. Ideally it would be nice to have a good digital SLR, with full manual modes and so forth. However, my bottom line is always “the best camera is the one you have with you”. This is what keeps us in the dust proof / water proof / point-and-shoot regime. We can take them anywhere (wet canyons, oceans, wind-driven sand on dunes, in the rain, etc.) and have hardly a care about them continuing to operate.

    The (current, no doubt being solved somewhere) downside of this class of camera (small, waterproof, point-and-shoot) is that they do not have real manual modes. Therefore, it’s unlikely that multiple exposures (like for a panorama) will be consistent enough that there will not be a noticeable difference in contrast / lighting / color / etc. The problem this creates is that – in the past – when stitching pictures together to form a panorama, those parameters needed to be consistent across all the photos in the panorama.

    Convict Lake, February 2010. Arriving at the scene, and climbing down into the lake’s outlet area, I was struck by the raw beauty. I took a hand held panorama, then thought “why not give this opportunity the chance it deserves” and went and fetched the tripod. I set up the tripod on top of the thin layer of ice on the outlet and took a series of shots in landscape mode (camera horizontal). I looked through the pictures, looked at the scene and noticed that in landscape mode I was not getting the full reflections of the peaks in the water. I reshot the entire scene in portrait mode / infinite focus with plenty of overlap between shots.

    At home, as I was catching up with my Google Reader, there was an article about “the best panorama stitching software” the writer had tried out. I followed the link, downloaded a couple of trial versions and quickly converged on the same answer – and now own a copy of PTGui Pro.

    20100217 Convict Lake Pano Crop Upsamp

    I let PTGui do its magic with the raw, unedited photos. I’m really happy with the resulting panorama. If you want to appreciate the technical accomplishment of PTGui, pan and zoom around in the picture and look for errors in the skyline or water where the pictures have been merged. I did this and can’t find anything.

    A few tips if you want to do your own awesome panoramas:

    1. Use a level tripod – if possible.
    2. Force your camera to make the fewest possible choices – i.e., force infinite focus, single white balance, whatever you can accomplish. Read The Friendly Manual.
    3. Lighting will be important – sometimes you won’t have a big choice (for instance, we were somewhat surprised to even make it to the top of Split Mountain, let alone plan for lighting), but if you have a choice, use the best lighting.
    4. Be sure to get enough overlap in your pictures – some writers recommend 1/3 of the scene or so on each side.
    5. You decide – lug around a heavy, fragile digital SLR and use lightweight panorama software, or carry a lightweight camera and use heavyweight panorama software…

    Here’s wishing you the best in your photographic endeavors!

    Namaste.

  • Things that go fast – Laptop Edition

    We get accustomed to things. Everyone knows that while using a computer, there are going to be times when you just sit and wait for the machine to become responsive. The main reason is due to one component of the system, the fundamentals of which haven’t changed much since the early 1950’s.

    The computer industry serves us up multi-core CPU’s running at multiples of GigaHertz, fast RAM, fast I/O, blah, blah, blah – the idiot child in the group, however, is the hard disk drive. With apologies to all the thousands of developers working hard at optimizing the performance of HDD’s (I spent 19 years of my life at this, too), really, it’s lipstick on a pig compared to the Solid State Drive, a disruptive technology that has finally become real and within reach of most of us.

  • Aligning Camera / Picture Times

    It’s inevitable  – despite good intentions, if there are multiple cameras at an event or on a trip, the timestamps on the pictures will be off.

    A partial list of reasons I’ve encountered:

    • Time zones,
    • daylight savings time,
    • never having set up the camera,
    • using different time bases (i.e., cell phone, the clock in the car, the clock on the bank)

    The easiest way to interleave pictures chronologically is to sort by time. This doesn’t work if time bases are different.

    Fortunately, digital cameras add a bunch of data to the picture file called EXIF data. The trick is to be able to edit the EXIF data and time shift a group of pictures. Continue reading  Post ID 1283


  • New Laptop with Vista

    I’ve read a lot of reviews on Vista – buggy, unstable, frustrating, can’t wait to upgrade to XP, etc. and then there are the unavoidable (admittedly entertaining) PC vs Mac commercials. I had a chance to work with a Mac this spring and didn’t find it any more intuitive or easier than a Windows PC. Plus I have a lot of valuable PC software, number one being Photoshop CS2. Emulation modes – forget it… Continue reading  Post ID 1283


  • Using Picasaweb to share pictures

    Key concepts:

    1. The pictures you want to share must be on your PC / MAC somewhere you can find them and where Picasa or iPhoto can locate them.
    2. Picasa and iPhoto are local applications running on your PC / MAC. Go here to download Picasa. Go here for help with Picasa.
    3. You can edit pictures in Picasa or iPhoto. You can also edit pictures in any external application like Photoshop, Easyshare, etc. Continue reading  Post ID 1283
