Recover Deleted Files

I’m super careful with files on my computer. Careful almost to the point of obsession. After having a hard drive crash and losing a bunch of data 15+ years ago, I made sure it would never happen again. But recently I broke one of my own rules and ended up in a bit of a mess. The rule is: get your files off of SD cards as soon as possible.

There are bunch of good reasons for this but a few are:

  • SD cards are easy to lose
  • SD cards are easy to damage
  • SD cards are easily corrupted

None of those bit me. The problem that bit me was user error. I left files on the SD card for a couple weeks because I was too lazy to put the card in the computer and copy them over. The exact sequence of mistakes is probably boring to read, but the bottom line is that I thought all of the old photos on the card had already been transferred off but only about 80% of them had. There were a bunch of “first day of school” photos that I hadn’t transferred off right away and I didn’t notice that fact before deleting them.

As soon as it happened, I realized what I had done and my stomach twisted into a knot. I just lost files not because of a software/hardware problem but because I was an idiot.

I immediately ejected the SD card from my computer and slid the lock lever over to prevent any further stupidity. Next it was time to find something to recover the files. When a computer deletes a file, it doesn’t actually overwrite the file, it just removes the entry from the “card catalog” that points to the actual file locations. So if you can carefully scan the disk and you know what the binary header of your file looked like, you can still read the old data.

If you search around for “recover lost files” there are tons of programs available and I believe two things are generally true:

  1. They’re going to cost quite a bit of money because they know you’re panicked.
  2. It’s a great way for hackers to get you to install spyware/viruses. You’re in a hurry and you click away without really checking the validity of the site.

I ended up using PhotoRec which is free, open source, and hopefully safe. It’s not very user friendly, but that was fine with me.

The tool worked ok, but it didn’t find any files on my first scan. I had only saved .CR2 (Cannon Raw) files and the tool didn’t have a scanner for those files included out of the box. Thankfully they allow you to add your own file signatures, so I whipped open a hex editor, figured out what the header of a CR2 file looks like and added a new signature.

After that it quickly plowed through my SD card and found the “deleted” files. It didn’t get 100% of them, but because I took about 100 pictures of Elijah in ~4 different poses, I still had plenty of good photos to choose from. The day was saved.

But this is one of those lessons that I’ll never forget. When you walk in the door with new pictures on your SD card, immediately copy them to your computer and get them backed up to cloud storage. And whenever I buy my next camera body, I’ll probably be buying one that has built-in WiFi syncing available. I might even check out those WiFi SD cards to see if they’re worth it.

XFinity For Roku

Earlier this year, Comcast launched an app for Roku, but I only just got around to installing it. It’s still in beta so you won’t get a full feature set, but it’s still an interesting move for the company.

Previously, if you have Comcast service and you want to add another TV in your house, you had to pony up $10/month or more for another box that sits with that TV. Ouch. Now they are offering you alternatives to that extra monthly bill.

For quite a while they’ve allowed you to stream to a browser window or a phone app. The main limitation there is that you have to be on your home network for it to work, but this has still given me a way to have football on out in the shop. I just connect my laptop to the TV and I’m good to go.

The Roku app makes this even easier. You can pick up a basic Roku for ~$30-40 if you don’t have one already. The XFinity app is free and voila, now you’ve got live TV via the Roku without an extra monthly fee. If you have their Cloud DVR service then  you can access those shows through the Roku interface. (Note that I haven’t tested that since we don’t have the Cloud DVR service.) The only downer for me right now is that I only get standard definition on most of the channels. That doesn’t happen for everyone and it should change when the app is out of beta.

This feels like a direct response to the rise in popularity of non-traditional TV services like DirectTV Now, YouTube TV, Sling TV, Playstation Vue, etc. Compared to those services, Comcast is coming at it from the other side (moving from traditional cable to internet) but it’s good to see them making moves in that direction.

Fantasy Football – Week 4

Seahawks! Now THAT was a fun game to watch. I liked the up tempo pacing of their offense (even if it does screw up my 30-second skip button between plays). The downside is that it means that their defense might not get a huge rest on drives that are duds. That did turn out to be the case in the first half so I was worried that we’d see another second half defensive breakdown, but that obviously didn’t happen as the offense set a franchise record for most second half points. The injury to Chris Carson was a big blow though. He looked like their featured back for the first four games but now they have to continue the search. Hopefully Procise and Rawls can get healthy and get moving downfield.

Logan’s domination of our league continued this week as I failed to even make him nervous. Dad and Luke are tied for second place and the rest of us are lagging behind them. Tim is still searching for his first win. Could he do it against undefeated Logan?

The Yahoo draft day projections had Logan in 6th and Dad in 8th which is a great data point to show how ineffective those rankings really are. Of course MY power ranking formula is my more valuable and accurate. We have four weeks in the books so it produces some results now:

1. Logan
2. Luke
3. Austin
4. Ben

A couple important notes for our league:

  • Bye weeks start this week so make sure you have a full roster.
  • Remember that our reminder emails aren’t working anymore. If you want reminders, that feature is available from the Yahoo website and/or the phone app.

On to the weekly awards…

Free Throw Summary

I might get a few more rounds completed in my “25 Free Throws A Day” challenge, but it’s getting dark so early that it’s unlikely I’ll have too many more. So let’s take a look at how the stats shook out.

  • I shot a total of 1625 free throws and made 1125 of them. (That doesn’t count the warm up free throws.) That comes out to 69%.
  • My five and ten round averages generally increased. At the end, my five round average was 21 and my 10 round average was 20.5.
  • My best was 22/25 and I hit that pretty early in the summer. I got it again a number of times but could never break through. I definitely choked a few times. For example, I once made it to 22/23 and proceeded to miss both of the next two shots because I was so excited about setting a new record. At the end, I finally got 23/25 a couple times.
  • I feel like a perfect streak is within reach. I might keep going with this next year until I make that happen. If I can do that, I’ll be 0.48% of the way to the record of 5221 consecutive free throws made.

This whole thing started as an excuse to get outside every evening so from that point of view it was a big success. I wanted to do a better job of enjoying our beautiful summer weather. It was fun to watch the improvement along the way.

If I do continue this next year, I think I’ll change it up a bit and count the most consecutive free throws made. That makes it a lot easier to “warm up”. This year I struggled with the warm up period. Should I just shoot until I feel like I’m doing well and start counting? Or should I take 10 warmups every time? It was kind of squishy. Counting the number of consecutive free throws made means that I don’t have to worry about a warm up period and I can shoot for as long as I want before stopping. I have plenty of time to mull that over while I wait for the sun to return next spring/summer.

Lego Whitening

As I dug through my old Legos as my parents house, it was hard to ignore how yellow the white pieces had become. I have two fairly big sets (Lego Model Team) with lots of white Legos and I was curious how hard it was to make them white again.

First of all, why does white plastic turn yellow over time? The core reason is that bromine is added to the plastic as a fire retardant. Over time, that chemical reacts with the plastic and produces a yellow color. The change can be accelerated by light, especially sunlight. Thankfully, the process can also be reversed… with SCIENCE!

There are many websites out there describing various ways to whiten Legos, but I’ll use the one from the Jangbricks video below. The basic steps are:

  1. Wash with soap and water, brush
  2. Put on eye protection and water proof gloves
  3. Find a plastic container that fits the parts
  4. Completely submerge the parts in 3% hydrogen peroxide
  5. Put in a sunny spot (UV light), 3-4 hours (5 at the most) if it’s mid day direct sunlight
  6. Pop the bubles every hour to make sure the water stays in contact and completely wet
  7. Rinse with water and dry (salad spinner)
  8. Spread the parts out to air dry
  9. Reuse the hydrogen peroxide several times. When it stops bubbling enough, dump it down the drain.

It’s hard to find days with strong sunshine this time of year, but we did get some sun last weekend. I’d say we got about 80% of the way there. I’m debating whether I want to try to find some artificial lights to replace the sunlight piece of the puzzle or just wait until next summer to try again.

Yard Watering Recap

We’re coming out of the dry season, and what a dry season it was. We tied the warmest summer ever (1967) and got the record for the driest summer ever (1910). Even with all that, I’m happy to say that our yard stayed green and I think I used about the minimum amount of water possible to make that happen. Here’s the data from our sprinkler system showing the cumulative gallons used by year:

The 2015 line is especially interesting. It was very hot and dry that summer too, and even with all that water, my yard died. I had the settings really dialed in this year. The key was getting the runtime for each zone set properly and then trusting the Zimmerman algorithm inside OpenSprinkler to automatically adjust those runtimes based on the previous day’s humidity, temp precipitation and the forecasted precipitation. I only overrode it once when we had a streak of weather in the mid-high 90s.

The rain came a little earlier than it has the past two years so I’ve already shut it off, at least for now. The yard looks healthy enough and the weather is wet enough that I doubt I’ll need to run it again.

Fantasy Football – Week 3

The Seahawks are 1-2. At least they scored a touchdown AND an extra point. There were some flashes of offense but it clearly wasn’t enough. After the game, I told a Packer fan that the odds weren’t looking good for a Seahawks/Packers playoff game. The Seahawks were pretty good odds for winning the Super Bowl before the season. Kudos if you were smart enough to bet against that. I’m not saying you can predict a season from 3 games, but they clearly aren’t dominating the league early on, even against teams like the 49ers.

Our league had low scores for the first two weeks but that ended this week with almost everyone breaking 100. Logan is the last man standing with an undefeated record. I’ll take the next shot at him in Week 4.

This Week This Season All-Time
Highest Team Score Luke had 161.89 Ben had 124.88 (Week 2) Tim 200.51 (2015)

Allowance

My sister and I never had an allowance when we were growing up, but I also remember having a few bucks here and there so it worked out fine. I’m it would have worked out fine for Elijah too, but Tyla and I have really enjoyed having our own individual allowances (we call it a “fun budget”) so I liked the idea of doing one for Elijah too and using it as an educational tool.

Natali Morris has a couple great posts on the topic and I’m largely stealing the ideas from her, but here is how we set it up for now:

  • We’re not paying him to do chores. Everyone in our house does chores. It’s expected, not rewarded.
  • Each Saturday, he’ll get $4. $1 goes in the piggy bank for long term savings. (Eventually we’ll migrate that to an actual child bank account.) $1 is for donating to church. And the remaining $2 go in his spending jar.
  • For now, everything in his spending jar is a one dollar bill. That makes it easier to explain how much money he has and how much he needs for a particular toy.

There are a few ideas for expanding this in the future beyond what I mentioned above:

  • If he wants to earn additional money, we’ll find some jobs for him to do around the house (not chores!)
  • After he has a few purchases under his belt, I’m willing to let him buy something that he doesn’t have money for, but I will charge him interest on that loan.

It seems like a lot for a four year old to grasp, but so far so good. If this works out, we have a chance at raising a kid who understands the value of money, saving, and staying out of debt. And oh yeah the “Can I have X? PLEEEEEAAAASE?” questions while in the toy aisle have a very easy answer now: “You can spend your own money on this if you want it.”

P.S. I walked into the bank and asked for $100 in one dollar bills. As soon as those words came out of my mouth, I said, “Oh. Wow. That sounded way more dirty than I thought it would. Honestly, it’s for an allowance for my kid.” The teller got a good laugh out of it and said she sees lots of interesting stuff.

Fantasy Football – Week 2

The Seahawks got their first win of the season. Barely. Against the 49ers. That’s hardly inspiring. They also got their first touchdown of the season but we’ll keep waiting for that first extra point. It was nice to see Russell Wilson happily scrambling around though. Jimmy Graham has a total of 4 catches for 9 yards this year. Hopefully they can get him back on track and/or he can get through whatever injury is slowing him down.

In our league, all four of the undefeated teams faced each other. Logan and I came out on top so we are now the only undefeated teams left. Logan is leading our league in roster moves already this year. He has 5 and the next highest is 2. I think his mid to late season roster moves were really what set him apart last year so maybe we can gang up on him this year by being better about picking people up off waivers.

Samsung Gear VR

My first experience with virtual reality was probably playing with a Nintendo Virtual Boy in a store in the 90s. It has progressed a wee bit since then and now the phone that you carry in your pocket can provide a pretty impressive virtual reality experience.

Thanks to Don and Megan for getting me a Samsung Gear VR for my birthday! I had a Google Cardboard set up from last year and that was enough to convince me that it could be really cool but not good enough to really scratch the itch. The Gear VR is a very nice experience.

Setup was pretty easy but required a lot of app installs on my phone. But once that was done, I plugged the phone into the goggles, adjusted the straps, and entered the world of virtual reality. I’m still learning my way around, but so far the coolest thing I’ve done is take a flight with the Blue Angels. 2D videos are great, but being able to move your head around while watching the video really takes it to another level. It’s an awesome experience!

I can’t see using this for long periods of time on a regular basis, but it’s really neat to see how far the technology has come. It makes me want to experience a full-blown setup with dedicated goggles driven by a beefy computer (but not nearly enough to pay for all that myself!) I feel like we’re getting closer and closer to my dream video game: Forza Motorsport VR Edition. It has to be coming some day. RIght? Pleeeeeeeeease?
