Android Lollipop is Incredibly, Unbelievably Bad

Those who know me will attest that it takes a vary serious effort to rattle me to the point where I'd start saying things like "I hate X". I am even more tolerant to the shortcomings of software products. For example, I never shared majority's outspokenly negative view of Windows ME or Windows Vista (Starting with Vista "Start" menu has become moot as search was the quickest way to find and start a program or a document). I could easily deal with problems of those operating systems. In fact, I considered them rather minor, and the reaction of the public overblown. And, I started using computers when MS DOS was the main OS, then I switched to Windows 3.1 and used every version of Windows since then. I spent a few so-so years in the iOS ecosystem and about as much in the Android universe. I have never complained. So now that we've established the baseline of my pain threshold, let me get to the point.

Android Lollipop, you did it. I hate you. My wife does too. In my view, Lollipop is the worst OS, bar none. We used to have Google Nexus 4 phones running Kit Kat smoothly and dutifully. No complaints at all. One day they were "upgraded" to Lollipop, which made our handsets unusable. Not just very slow, but Lollipop terminating and unloading our apps was simply incredible. Podcasts that stop in the middle while running in the background? Check. Phone app that takes 45 seconds to show up while you need to make a call rather urgently? Check. Camera app that shows up a minute after the moment of interest has passed, and then holding your phone hostage for another 30-40 seconds? Oh yeah, all the time! Keyboard that draws letters in the virtual keyboard "button" squares at the rate of one per second? I saw that too.

After tolerating that disaster for a couple of months, we sold Nexus 4 sets on eBay and got LG G2s. It was a great hardware for a value phone, running Kit Kat simply beautifully: not a hitch, very snappy - just a joy to use. Then the terrible day has come - the day of forcible upgrade by LG or whoever is the overlord pushing "upgrades" to our phones. Now our LG G2s are almost as slow and unbearable as Nexus 4s were, except we can't justify buying another hardware less than a year after previous phone purchase. We are stuck in the Lollipop inferno for now.

I understand that this could have been phone manufacturer's fault, but eventually the buck stops with Google. Brief internet search shows that even most recent and expensive hardware is susceptible to the Lollipop slowness curse just as well. Sadly, our exit from Apple ecosystem few years before was precipitated by their very similar software update approach that made the experience of keeping up with hardware miserable.

There is simply no excuse for the Android Lollipop being so incredibly bad. It's really hard to fathom why and how thies disaster of an OS has passed the mesh of Google quality control. I will give Google one more chance with Marshmallow, but if it turns out anything like the experience with the Lollipop, the dreaded switch of the ecosystems might be the only way forward..

For shame, Google.

The End of Profit

Finally I get to write my own "The End of..." piece, albeit just in my own blog. To not bore anyone with the requisite amount of text appropriate for the title, here's just the executive summary.

The never-ending quest of the business world to increase efficiency means increased commoditization of every product, with which margins become really thin, making it very difficult to turn any profit at smaller scale, which in turn would disincentivise new business formatiuon, which will depresses the economy and wages. Where did I make an error here?

Amazon Fire TV 4K is Alright, Not Mind-Blowing

Amazon has pulled ahead from Google by releasing the 4K-capable version of the Fire TV mini-STB. Google's Chromecast does not yet have a 4K game. Until recently it was only $200 Nvidia Shield console ($225 with the remote you want) that supported 4K.

So the question for 4K folks is: Amazon Fire TV or Nvidia Shield? Or, even, why bother with dongles and set-top boxes instead of just using Smart TV capabilities of your 4K TV set?

(Again, I am not a gamer, I am interested in high-quality media streaming, so my take on this reflects only media part of the equation.)

Here's the things: YouTube, as of now, holds advantage of the 4K content available. In order to play YouTube 4K content, your system needs to have hardware support of VP9 codec - 4K format used by YouTube. No all 4K TV sets support it. For example, Vizio, which combines excellent features with affordability, can't play YouTube at 4K - a major drawback, IMO. However, a TV set that does run YouTube at 4K with comparable feature set, will cost you about $800 more. Now, to me this $800 gap for just a couple of features I miss, main of which is 4K YouTube, is the space where 4K STBs come in.

Until today, just about the only 4K STB game in town was Nvidia Shield console. But with today's announcement of Amazon Fire TV, we've got competition. And to me decision for which one to get comes down to this:
FeaturesNvidia ShieldAmazon New Fire Tv
Price$200$100
4K Frame Rate60fps30fps
YouTube 4K SupportYes?? No

Update:
Yep, from its specs, it's unclear whether new Fire TV supports VP9 YouTube codec. Until I can confirm it's a "yes", for me Fire TV is not a contender. If the answer is yes, then I can imagine trading extra 30fps of Shield for a $100 discount.
According to 4K.com, YouTube 4K content cannot be watched due to lack of VP9 codec support by the new Fire TV. So I $100 price tag seems too high for this device.

Entering 4K Video World: Hardware Upgrades and Process Changes

4K video resolution is arriving - not really slowly, but in a somewhat weird way: 4K content is sparse, while consumer-grade hardware to produce and consume 4K content is getting affordable, from GoPro 4 Black and Sony FDR-AX33 camcorders costing under a $1000, to plenty of sub-$1,000 4K TV sets. This price point is a sweet spot where a video geek can get the hardware and not be overrun with guilt that must ruin the psyche of a real early adopter.

Watching raw 4K footage on a 4K TV is not something I can deal with - video has to be edited first, and in the 4K video case, it means your computer will have to move and process a whole lot more data. Which in turn means upgrades, and no matter how exciting it is for you and me, it means keeping costs down to make this all bearable for our dear sane family members.

Start with a monitor: your HD computer monitor will need to be upgraded to see the glory of 4K. I got Acer S277HK. It's not perfect: backlight is bleeding over at the corners pretty badly, but it's 4K, it's IPS, it has HDMI 2.0 in addition to the DisplayPort so it can be connected not only to a computer in a pinch, it has built-in speakers so I don' have to waste desk space for speakers, and it's not ridiculously expensive. I am very happy with it, running on Windows 10. Everything look massively more gorgeous on it than on a regular HD monitor.

To drive the 4K monitor, I got the least expensive video card I could find for the purpose, which is just about any GeForce 750Ti - it won't handle 4K gaming, but should be plenty for 4K video editing. I got the EVGA, which worked out quite nicely. It also has a fairy quite fan, and I really like when my system is quiet. GeForce 750 (non-Ti) might have worked, but based on reviews it looked iffy, so I went with the Ti, which seems to be very much up to the task.

Now, here's something I didn't experience in a while: after copying 100 Mbit/s 4K footage shot on Sony FDR-AX33 from an SD card on to the 2TB spindle SATA drive, I found that playing back 4K 100Mbit video from the spindle is all jittery as heck. I felt it is 90's all over again. Now, how do you fight this? The largest 4K clip I have is about 46 Gig and I definitely will have lots of these in the future. A reasonably priced large-capacity SSD that would provide adequate performance still costs about $250 on sale. At only 0.9 TB, it won't take very long to fill it up with 4K clips. So I got an idea: replace the spindle drive with the SSD, and to save the space, get Amazon Cloud Drive Unlimited. At $60 a year, and assuming the price will go down in the future, unlimited cloud storage looks very attractive for anyone planning to edit 4K videos. As an Amazon Prime user, I have been relying on complimentary Amazon Cloud to backup my pictures for a while. Using Amazon Cloud Drive by itself is not a particularly polished experience: one has to use awkward Amazon Cloud Client to upload files, which is a far cry from, say, DropBox quiet syncing. So although in theory Amazon Cloud Drive Unlimited seemed like a good option, I still wasn't sure how the whole workflow would look like, until I discovered the Odrive - the syncing client Amazon Cloud Drive sorely misses.

ODrive is the secret sauce that made this whole thing come together. Now all pieces were falling into places: upload all your raw footage to the Amazon Cloud Drive Unlimited and using Odrive, unsync folders with massive raw 4K footage to save the space on the SSD. When editing video, sync only folder(s) that hold 4K footage you are working with. Once done, unsync to free space. Rinse and repeat. This way your large-capacity SSD drive will hold only your pictures and the minimum number of big 4K video clips. That can easily be managed with probably even a 512GB SSD.

Now if initial syncing of the 4k raw footage up to the Amazon Cloud Drive won't run into the ridiculous and dreaded 300GB data cap of the blood-sucking Comcast (Update: oh yeah, I did - see update below), I should be all set for editing my 4K videos on a budget, using VideoStudio X8 Pro, and not having nervous breakdowns due to fears of running out of disk space or slow hard drive performance.

Finally, once I finish editing a few 4K videos, I will stop memorizing the content of the awesome Rtings.com and get an actual 4K TV to enjoy the fruits of my labors.

Update: ODrive Windows client crashes fairly regularly. If it crashes in the middle of uploading a large file, it starts over. It crashed several times trying (and never succeeding) to upload my 46GB 1hr+/100Mbit/s 4K clip, which took my Comcast data usage to 670GB, while I never reached the 300GB cap before. Comcast forgives first three months of overages under the "courtesy months" policy. I'll is that's the case when the bill shows up.

The Search Is Over

Google found out that "When you look at people who don’t go to school and make their way in the world, those are exceptional human beings. And we should do everything we can to find those people."

Dear Google, don't kill yourself: the search is over, I am right here. You are welcome.

On Being Rational

I got no well-structured thoughts on the subject. For now it's just a list of points for future elaboration.

  1. Being rational (having common sense) means being persuadable by evidence. Everyone will agree with with, but most people will firmly hold on to their deeply-held irrational convictions.

  2. Majority of opinions we hold are prejudices, biases, and instilled dogmas, rather than tested assumptions that were proven to be correct. Our identities are largely based on these untested opinions. Parting ways with one's identity is an extremely traumatic experience, hence people often would rather die than admit they were spectacularly wrong, even in the face of incontrovertible evidence. Early-formed, quickly-formed and strongly-embraced identities are the surest way to becoming deeply irrational.

  3. Rationality can be made more wide-spread if it's treated as a form of intellectual hygiene: compensating for own biases and stamping out fallacies in ones thinking is not natural, but also not terribly difficult: it can be learned, and the habit of questioning own assumptions can be maintained through practice, like washing hands and brushing teeth. To that end, rhetoric and logic should be taught, with spotting fallacies being the most important skill practiced in lab exercises. Ability to detect untrustworthy sources of information is not a natural proclivity either because it requires ability to adjust for own biases. But that too is a reasonably easy skill to acquire.

  4. Historically, being rational was not the most advantageous behavior: proving that Earth is not at the center of the Universe could get you killed. Allegiance to the tribe was valued more than being right about facts. Repeating disproved theories as an article of faith is just a statement of allegiance to the tribe, to reassure identity, and to get protection and the status among peers. As tribes become less essential in providing security for individuals, mutants who practice rationality are free to use feedback loops for quickly iterating through trial and error in chasing larger status goals: having much larger scale of impact and acquiring more wealth.

  5. Most opinions stated on TVs are not backed up by anything, and usually are pile of fallacies.

  6. The most exciting word for a rational person is "because". Claim without proof means nothing.

  7. In the long run, incentives inevitably trump culture. Aspirations and convictions melt away as compliance with incentives get justified even if incentives contradict views dictated by the culture. Structuring incentives correctly is more important than efficient day-to-day management of performance problems.

  8. Being right in business was always more profitable, but few businesses until now were structured to separate clear performance data from the noise of subjective opinions about the contributor. Also, even if a business was successful vs the competition due to acting in a rational manner, until recently businesses didn't have the global reach to compel the competition to also adopt measuring performance. Current situation where self-measuring businesses get very decisive competitive advantage is the single largest contributing factor for increased rationality in the society in general.

  9. Big Data dramatically simplifies and reduces costs of searching for evidence.

  10. Problem: when measured criteria are too few and simplistic, incentives get narrowed down to focusing on passing the test at any cost, including taking on insane workloads and cheating. Another problem is negative motivational power of measuring one's performance: people get turned off if they fear they may score poorly, leading to the vicious cycle of "low performance => poor score => even lower performance".

  11. Cooperation is more profitable than confrontation. It's obvious on the surface, but in evolutionary terms, humans had such a small amount of resources throughout the history, that someone's benefit almost certainly was somebody's loss, hence zero-sum mentality took hold and still dominates (sports, wars and border conflicts lasting well into the era of potential abundance). That's why it looks like humans programmed not to truly enjoy their success unless competitor loses. Most successful societies are those where trust covers widest possible number of people. That's not really natural, as evolution taught us to trust members only inside small social network: a family, a tribe, ethnic group, etc. That's why corrupt and brutal but familiar local leaders are routinely elected and stay in power as long as they can maintain the fear of the larger groups of outsiders even if the leader produces dismal outcomes for the group.

  12. Adding value (working) has become more profitable than taking property of others (war) very recently in historical terms. That's another facet of the reasoning why humans are ultimately held down by using zero-sum thinking as a default route.

  13. From evolutionary perspective, status among peers is the only important measure of success because it lead to reproductive advantage. Hence physiologically status is more important than wealth because wealth is only a proxy for status. Since status competition is zero-sum by definition, the question is "how much money does one really need" is moot: winner will be satisfied with one penny as long as everyone else got nothing.
If you agree with what I wrote above, you are in danger of being irrational as I made lots of claims without providing any proof or references. :-)
