My wife: I missed the turn.

Me: that's OK, now we can stop at little Cesar's for a hot'n'ready (joking).

My wife: oh, we need toilet paper!

FedEx overcharging with online purchases

So I recently purchased shipping online from +FedEx. At the time of the purchase I was quoted at $13.78 online. I know for two reasons. First, I enter all my transactions and track everything using YNAB (You Need a Budget). Second, I just went online and set up a shipment to verify the cost. It was the same. 

Today as I'm downloading my to reconcile my accounts, I notice that +FedEx  charged my $20.70!!!  What the hell! I know most people don't enter their transactions personally and reconcile their accounts anymore. Most people would never catch this. This is MAJORLY shady and needs an explanation.

Infurious Demogarte
The Oculus Rift has drifted in and out of tech news for the past two years and the information that filters out is more and more promising every month.  Think the Rift is only for gaming? You may be pleasantly surprised. While it's true that the Oculus Rift is going to revolutionize the gaming industry,…

This gives "boat accident" a whole new meaning.
This was no boat accident. But it is the ultimate tribute to the most famous shark movie ever made. Crave chats with the crafty fan who may or may not be blamed in future therapy sessions.

So while playing cards I got angry when my dad for on to me for looking at my phone because I felt it was unjustified. I them threw a little tantrum and tossed it across the room 😒.

It was fine as I knew it would be, but I accidentally took a picture at the same time. This is the awesome result.

+Russell Holly +Android Central One of the best 810 analyses I've seen.
 
Early findings on M9 / 810 - anecdotal thermal and throttling stuff.

For a primer, the only other phone out there with 810 is G Flex 2. So that's going to be one of our main points of comparison. And no, this isn't about trashing the M9, it's about evaluating Snapdragon 810. I like the M9 just fine so far.

Relevant figures: S810 - 4x A57 CPU cores at ~2GHz, 4x A53 (low-power) cores at ~1.6GHz.

Tools: Geekbench CPU stress test (not publicly available), Seek Thermal IR camera, my eyeballs / hands, CPU-Z for monitoring core clock speeds.

G Flex 2 exhibits probably some of the most aggressive processor throttling of any smartphone in existence. A CPU stress test turns 2 of its "high-power" A57 cores off within two minutes to keep under LG's set thermal ceiling, and within another few minutes, the remaining two A57s go into limp mode at 384MHz. During this time, the A53 low-power cores stay active at the full 1.6GHz. Once the A57s are in limp mode, the A53s are doing basically all the heavy lifting, and the phone slows down a lot. This is because LG is doggedly managing the internal temperature of the phone, even in benchmarks.

The M9 exhibits similar behavior under a CPU stress test, but seems to have a higher thermal ceiling under "ordinary" usage than the G Flex 2, so the throttling is less aggressive. The A57 cores, under high load, all stay active, but in no time during my testing did I observe them above 1.7GHz (1728MHz to be exact), despite being rated for 2.0GHz... which is kind of concerning. For the first few minutes, the A57s bounced between 1GHz and 1.5GHz playing thermal hot potato while the A53s stayed locked in at 1.6GHz (as on the G Flex 2). After a few minutes, though, as temperatures rose to what I'm guessing is HTC's thermal ceiling, the A57s slowed down to 900-1200MHz, then to 800-1200MHz, then to 700-1000MHz, then to 600-900MHz. Eventually (maybe 10 minutes in), the A57s all just dropped to 633MHz and stayed there, indicating limp mode was achieved, and the A53s were doing most of the work.

Now, a CPU stress test isn't actually a great way to generate external heat. The best way to make a mobile device hot is to run the GPS and cellular radio a lot (download an app, use navigation) or in some cases work the GPU playing intensive games. The CPU stress test shouldn't really get a phone all that hot because the main source of heat is being very actively controlled by the CPU governor to keep temperatures down.

The point of this test is to show that, when bogged down with heat-soak contributed to by other components, the Snapdragon 810 will resort to pretty aggressive throttling, and do so relatively quickly. A Snapdragon 805 in the same situation will throttle some, but the comparative loss in performance will be substantially lower.

Because HTC has left the M9 basically un-governed in benchmark apps, it's hard to tell how much the throttling impacts CPU performance statistically. It's quite happy to run Geekbunch CPU bench loops until it hits 115F+ (46C) external temperature, which is pretty warm. The G Flex 2 has managed thermals even in benchmarks, so it takes a 40-60% single-thread performance hit and a 30%+ multi-thread performance hit once it's at that thermal "ceiling," but the temperature doesn't get very high at all.

For a control, a Snapdragon 805 in a Note 4 was used, and that device experienced maybe a 10-15% single-thread drop and a 5-10% multi-thread performance drop when running through the Geekbench 3 CPU cycles.

The peak temperatures aren't really important so much as the mounting evidence that Snapdragon 810 just isn't a very good high-end chip in something as small as a phone. The thermals require aggressive CPU management in daily usage that effectively neuters the processor during extended usage or high thermal load situations (navigation, high data consumption, high screen brightness, etc.).

Apparently. It's not every time, but it's often enough that it is very disrupting.

Yesterday, I posted that my family recently got hit with a life-changing event. I want to share a little bit more about that today. 

To get to the point, my wife and I found out our two-year old has a chronic kidney disease called Chronic Nephrotic Syndrome. Basically, his kidneys aren't working as they should, and they are irreparable. In order to live, he's going to need a kidney transplant, but he can't even have that done until he effectively doubles in size. This is a difficult task in children with any chronic disease, but the kidneys are especially crucial in growth. It's going to be a long, hard road that will perhaps take two years or longer. In the meantime, he's going to require three weekly dialysis treatments.

For those of you who are interested in the longer version of the story, here it is. I'll try to keep it as simple as possible.

Axten has always been a small baby, much smaller than other children his age. We just assumed that this was because my wife and I aren't very big people - her being 5'4" and me only 5'6". He's also a very picky eater, but that's not uncommon for a two year old. We figured he'd grow out of it. A few months ago, we started noticing swelling around his eyes, mostly in the morning when he wakes up. A lot of kids have allergies, so we just chalked that one up to the dusty Texas atmosphere.

Turns out those were all the first signs of a serious kidney disease. It wasn't until last week when he came down with the flu that we knew something more was wrong, when his feet and legs started swelling. It was the day after Christmas and I decided to take him to the ER because of the swelling and lethargy. After one look the ER doctor told me to take him to the Children's Hospital in Dallas immediately. We've been here ever since.

We had no idea what we were in for. We were in the ER for six or seven hours while they ran all sorts of tests on him. He was severely dehydrated from fever, which sent his kidneys into overdrive. Apparently they were functioning just enough to get by before he became ill, and the sickness was just too much for them to handle. Within 24 hours of arriving at Children's, we went from thinking he had some sort of flu and infection to finding out he has failing kidneys, a surgery to install a hemodialysis catheter, and the first round of dialysis treatment to clean his blood. He has handled it all like a champ, especially since he's so small. I nicknamed him Tiny Tank, because honestly, he's just tough as nails. 

I've never experienced anything so terrifying in my life. We're still trying to adjust to what's happening and the new life we'll have moving forward. He's already had four dialysis treatments, but has responded exceptionally well to them, which is a good start. After spending three days in the intensive care unit, we've been in a regular room for a couple of days. Eventually we'll get to go home, but we're still not sure when that will be. 

We have a long, hard road ahead of us that I never could have expected. I'd like to ask that everyone keep us and Ax in your thoughts and prayers. This all happened so suddenly we're still trying to figure it out. Honestly, it's overwhelming. I still can't believe any of this is real. 

If you'd like to help out financially, my sister-in-law started a GoFundMe account to raise money for his treatment. I don't want anyone to feel obligated by any means (and I'm honestly not sure how I feel about sharing this link in the first place), but I've had several requests for a way to donate since we first started telling people, so I'm sharing it here, too. The link is attached. 

Thanks for reading. Just typing this up has been cathartic for me. 
I have created this account in hopes of raising money for medical expenses for my nephew Axten and his parents. On December 26, 2014 their lives changed. Axten is two years old and will be three in February. He had been sick for a few days and just not getting better at all. My sister noticed his...

This place is brand new and they are SPECTACULAR. We are getting it close to once a week now. The food is very clean and not at all greasy like most Chinese food. It actually reminds me of Pei Wei. They also advertise no MSG which is HUGE for a Chinese Restaurant. Additionally, my parents happened to discover it at the same time and sent me a text recommending it without any mention from me. I honestly can't say enough about this place. Even the prices are great. Give it a try, you won't regret it.
