Saucony Kinvara Running Socks Review
My first impression is that they have a nice hugging fit without being tight, They also have a nice amount of cushion without being hot. I think one of the features I like best is the heel tab. It is a little thicker than the rest of the sock and really protects the back of your achilles tendon from the back of your shoe. I really like low cut socks, but the worst is when they ride down enough for chaffing to happen. The heel tab really makes that an impossibility.
I got out for a 10 mile run in them yesterday and I really didn't even have to think about socks the whole time. That is a win for me.
Overall I'm very pleased with the socks and will probably get more pairs of them in the future.

2014 Marathon #2 Training Begins Today
I wanted to start with a shoutout to my nutrition sponsor Hammer Nutrition! I have been using their products for about a year and have been very happy with the results. Hammer Gel and Endurolyte Fizz tablets are my go to for fueling and electrolyte replacement. I'm hoping to do a little better with weekly updates this time around. So stay tuned!

Blender Add-On: Selection Sets Version 0.3 (updates)
It is a quick way to create ad-hoc groups of items that can be reselected easily. Simply select some items and choose the plus button to add a new set. The items in the set are then displayed below.
Click the Cursor select button to select the objects in the selected group. To add more items to a group, select the group, then select more objects, then click the + in the lower list. You can also remove objects from a group in the lower list. This is a very early release (hence version 0.1) but I feel like it is already useful when Blender groups are too heavy handed.
While I applaud what the new Blender Marketplace is doing, I'm more of a give it away and let people support what they love sort of guy. So if you love this or any of my tutorials and want to say thanks, consider sending me some Amazon cash in any amount you feel is appropriate! Just send it to johnny.matthews@gmail.com. Make sure to tell me in the message what thing you are sending the appreciation for :)

Updated to Version 0.3 (download link)
Changes in Version 0.3
- Set names auto-fix duplicates (which caused problems)
- Clicking on an operator changes selected set
- Icon Spacing
- Better Index Handling
- Icons in list box

Creating a Stylized Snowflake
Starting from a clean scene in overhead view, Add a Circle (Shift-A) with 12 verts (F6 and change verts)
Extrude the circle with scaling in (E then S) a couple times then merge the inner most circle at the center (W->Merge->At Center).
Extrude the top 3 verts constrained along the Y axis (MMB during extrude)

Striping a Curve in Blender/Cycles
To start we add a bezier curve and a bezier circle, then in the curve properties tab for the curve object, we add a bevel object of the curve. This ends us up with a simple tube looking object.
We can of course assign it a uniform texture, but what if we want stripes?
We could add a checker texture to start, but that does not map nicely by default.
As you can see here, mapping an image can also be good, with or without the striping! The Mapping Node can really make this easy as well.

Going from Blender to 2k Digital Cinema DCP
- Sources: To start, I created my Blender scene and collected my audio files
- Render #1: Render the Blender Scene into a series of 16 bit TIFF files at full resolution
- 2048x858 with square pixels (1:1 aspect ratio)
- Composite: Using my tiff files and my audio, I created a second Blender project to composite the sources into what I wanted the final project to look and sound like. For my project, I used Stereo audio, so I didn't mess with the surround sound options. I will be looking into that for future projects.
- Render #2:
- Render out the Composite to 16 Bit TIFF image sequence with any additional compositing/effects/etc
- Create the audio mixdown. This is where you could end up with a stereo file or a series of files for surround
- Video Path to MXF (Material Exchange Format)
- Using openDCP, convert the TIFF files to a JPEG2000 image sequence
- Encapsulate the JPEG2000 image sequence in an MXF file
- Audio Path to MXF
- Process the resultant audio files as needed (compression, normalization, etc)
- Make sure the project will save as 24bit uncompressed WAV at 48k or 96k
- Save each channel as a separate mono file (e.g. mix-Left.wav, mix-Right.wav)
- Use openDCP to encapsulate the audio in an MXF file
- Use openDCP to combine the MXF into a DCP (digital cinema package)
- Optional Convert the DCP into a quicktime file for testing on your local computer with ffmpeg
Resolution:
First off there is aspect ratio. A flat 2k render is 2048x1080. But that is not what the 2k digital cinema projects at. The aspect ratio is 2.39:1, so actual render resolution is 2048x858.
Source Files:
Image:
DCP (digital cinema package) uses JPEG2000 format. Luckily there is a handy free utility called openDCP which can convert 16 bit TIFF files into JPEG2000. So when I rendered out my blender scenes, I made sure that I was exporting to 16 bit RGB TIFF files. Then using openDCP, I convert the individual frames to JPEG2000 files.
Audio:
I used the blender compositor to cut up and arrange my audio and export. The audio required for DCP is a mono .WAV Signed PCM 24 bit format at 48k or 96k sampling rate file for each channel. I used Audacity to upconvert the mp3 files I exported. Make sure that you have a separate file for each channel. Stereo is 2 channels, 5.1 is 6 channels, etc.
There are other items you can do that I haven't touched yet as well.
Intermediate Files:
openDCP then lets you package your JPEG2000 files into a MXF file, as well as your audio source files into another MXF file. These are the 2 files that will be used to create your final DCP folder.
DCP Output:
One main thing I learned is that DCP is not a file. It is a series of files, some contain the data and others contain definitions of that data. The last thing you do with openDCP is combine all these items into your DCP. Once finished you are left with a folder with 6 files. This folder can be ingested into a digital cinema system and played back.
There are not many options for testing you DCP file on your local computer. EasyDCP player has a trial version that will let you play the first 15 seconds of a DCP. Which will let you know if it is working. But another thing you can do is convert your DCP into a quicktime file, to see what your output looks like. The newest builds of ffmpeg can convert MXF to Quicktime. The following line of code will do it.
ffmpeg -i videofile.mxf -i audiofile.mxf -c:v prores -c:a copy testfile.mov
Where the videofile and audiofile are the mxf files that were placed in your DCP folder.

5 Lessons I learned at the 2014 Country Music Marathon
I guess I could call the 2014 Country Music Marathon in Nashville, TN the first full marathon that almost wasn't, was almost a half and then at the last second became a full once more.
After training for 13 weeks, I had my first serious bout with IT band syndrome. I adjusted my training, changed my running style and tried to get myself of track to at least run the half marathon in Nashville. After I got there and realized that the only thing I had to do differently to run the half rather than the full was to just run the half course and the timing chip would do the rest, I realized that I could wait to decide until the cutoff point between the 2 races at mile 11. So feeling strong at that point I went left when the half marathoners went right. It took a while (5:14:15) but I finished and learned some good lessons for next time both in the race and in training.
Lesson 1) Since I have started running with a forefoot strike, my calves do a LOT more work while running and they were the first thing to start aching around mile 13 or so and then they were toast by mile 20 leading me back to my old form, while made my IT band knee pain fire up. So the lesson learned was before the next marathon, I need to focus more on calf strength.
Lesson 2) The next thing to really start bugging me was a nasty blister on the inside ball of my right foot. I think the toebox of my right shoe was just a little too loose and was sliding around on me. But instead of pulling over and dealing with it, I kept going. Lesson 2: Stop and make adjustments when needed rather than just pushing on.
Lesson 3) I trained for the last month using my Nathan VaporWrap hydration vest and was ready to take it with me on the course. It had pockets for everything I needed from nutrition and water to my camera, phone and car keys. As I crossed the pedestrian bridge from the LP field parking lot to the starting line, I was stopped by a policeman telling me that since my pack was not see-through, I would not be allowed to take it in. There had been nothing on the RnR website about not allowing hydration packs. I had to go back to my car and 1 hour before the race re-evaluate everything I was taking with me. Luckily I had my phone armband in the car, so I could still take it, and my Hammer Nutrition shirt and shorts have very good pockets on the back for some gels and my car key. I decided to carry my flask of Hammer Gel for the whole race. So I had to leave some items behind. I was not very happy and it derailed my attitude for a little while. But I made quick adjustments and moved on. So lesson 3: Even if you are sure something is allowed on the course, it might not be. Have a backup plan for your gear.
Lesson 4 & 5) These were lessons learned during training, On my first 18 miler I was completely toast by the time I got home. My mile splits had been all over the place and I felt terrible. After consulting with some of my fellow Hammer Athletes, I realized 2 things needed to change. 1st, I had gone out way too fast and was pushing too hard too soon in my workout. I needed to start out slower and build slowly using my heart rate gauge an "Endurance Zone". Second was that although I had been fueling at every 5-6 miles, and timing-wise this seemed to be ok, my body responded better to more frequent fueling. I found that fueling every 4 miles (which for me is every 32-45 minutes) really kept my energy levels up and feeling good. So even though my calves were just sore by mile 20 and my knee hurt by mile 21, I still had plenty of gas in the tank to keep moving all the way to the finish line. Hammer Gel and Perpetuem solids were my go to fuel source. So learn by trial and error how often YOUR body needs to refuel and stick to it!
My first marathon is something I will never forget. It was so much fun, sometimes it was effortless, sometimes it was painful, but in the end crossing the finish line was so very satisfying and I can't wait to do it again.

The Past Few Weeks: The Bad, the Good and the Ugly.
Week 6 was interesting to say the least. Lower mileage during the week ramping up for Saturday's 18 miler. I ended up going out after lunch on Saturday. It was low 30˚s with a brisk wind. Not quite as painfully cold as the week before (no ice on my water bottle this time). I was pumped about this run (and a little nervous to be honest) so I was eager to hit the road. Unfortunately I let my excitement for the new distance get the better of me and I went out too fast. My target average pace was supposed to be 9:45. I felt great the first 4 miles averaging 8:45. Mistake. By mile 10 I was hitting 10 minute miles and by the end it was around 11:30 minute miles and I hurt. My muscles were screaming at me for a while after that one.
28 miles for the week
I consulted with my awesome (and much more experienced) sponsored Hammer athlete group for some advice. Obviously pacing was brought up. I will be managing pace next time using my heart rate monitor to see if I can even out the whole thing and stay feeling better longer.
I also started reading a new book this last week. It is "Racing Weight" by Matt Fitzgerald. After having lost a great deal of weight, my previous hard cut diet was not working for me anymore. It got rid of the bulk of my fat stores but the last 15 pounds or so are gonna be stubborn, so I wanted to get a newer sustainable plan aimed at performance and getting lean, not getting skinny. So far it's pretty good stuff. I'll do a write up later in more depth.
The Good
Week 7 went better. My first 20 miler ever was a rainy 34 degree day. But I got out there and did it. I fueled more often and kept a more even pace throughout. I ended feeling much better than the previous week. A lot less sore and a lot happier with the whole experience.
33.5 miles for the week
Some Rest
Week 8 was a good rest week. I ended up putting in a lot less miles, but I was a good recovery week. I missed 1 workout on Saturday.
20 miles for the week
The Ugly
Week 9 : This winter has been the worst for training for my first full marathon. The bitterly cold weather has forced me to log way too many treadmill runs. But so far Saturdays have been 'good enough' to run outside. But sadly single digits and freshly iced roads made running outside not possibly for me. Seeing as it was scheduled only for a 16 miler, I decided to suck it up and do it on the treadmill. Lets just say that I am DONE with winter. 16 miles on a treadmill is miserable. 150 minutes of going NOWHERE! ugh. But I got it done and with a 2%-3% incline the whole time, I feel pretty good about the effort. I missed 1 workout this week.
29 Miles for the week
Next week is back to a 20 miler again. With 37 miles scheduled for the week. We will see how that treats me. 10 weeks until race day.

Week 5 Recap
The 16 miler on Saturday went well. I think it would have gone a little better had it not been for the cold. At 18°F it was a bit chillier than I like to run in, but there was no way I was gonna do 16 miles on the treadmill. So 3 layers of long sleeve shirts, 2 layers of gloves and my trusty cold gear tights, mask and a fleece headband and I was off. It was a first for me to have to break the ice off my water bottle valve to open it each time I took a drink. I averaged a 9:31 pace which is actually 14 sec/mile faster than my plan called for left me feeling good about the outing. Had a banana before the run, Perpetuum Solids about 4.5 miles in, Hammer Gel at miles 8 and 12. Also had an Endurolyte Fizz in my water bottle. Energy-wise I felt good throughout the run.
Total mileage for the week was 30.8 miles.

Marathon Training Week 3
2013 A Running Year in Review
- In late 2012 I had started running, then at the turn of the year, I decided to step up my running and start focusing on weight loss. I was about 230 pounds and dealing with the beginnings of some weight related health issues. I ramped up the running to 3-4 times a week @ 5k distance on the treadmill. By summer I had made it to about 175lbs. Since then I've been fluctuating from 175-185. I still have about 10-15 pounds to lose. That's for next year.
- June 1st, while visiting my folks in Phoenix, I ran 13.1 miles in a single workout for the first time. It took over 2 and a half hours, but I did it. It was a run to the top of South Mountain and back again. It was a truly inspirational moment watching the sun rise over the valley as I ran up the mountain road by myself.
- September 28th, I ran the FCC Preschool 5K for the 2nd year in a row and ran it 10 minutes faster than last year at 24m 55s. So there is my 5K PR
- October 27th, I ran my first 1/2 marathon in St Louis. The Rock 'n' Roll 1/2 Marathon was a great experience and let me set a 1:52:25 PR.
- December 25th, as a Christmas gift from my family, I registered for the Rock 'n' Roll - Country Music Marathon in Nashville, TN.
- December 28th, the last run of the year, I hit the 1134 mile mark for 2013.
