"I should add a note here to explain why Tesla is deploying partial autonomy now, rather than waiting until some point in the future. The most important reason is that, when used correctly, it is already significantly safer than a person driving by themselves and it would therefore be morally reprehensible to delay release simply for fear of bad press or some mercantile calculation of legal liability."

I'm at loss with +Samsung Mobile Android phones; it's almost as if there was some planned obsolescence in play, but that's not all; the Bluetooth seems to work way better with Cyanogenmod than Samsung firmware. Ultimately over the device lifetime, if using Samsung firmware, the Bluetooth gradually gets worse and finally stops working at all. WTF?

This Note 3 is now my second Samsung that exhibits same kind of behavior at two years of age: It gets gradually slower and slower and factory resets don't fix it. It develops trouble connecting to Bluetooth devices and in the end stops seeing most of them at all. The storage speed is fine and amount of free RAM doesn't seem to explain it. The previous one having similar issues was S2.

So, I've been playing around with it and tried different approaches:
1) On Note 3 with Samsung firmware the lag is tolerable after a factory reset, but it doesn't see Bluetooth devices. Heart rate meter, Beddit sensor and VIVE base stations all show on Bluetooth scan with Nexus 7 tablet but none show on Note 3.
2) On the same Note 3 with Cyanogenmod the lag is intolerable especially in games, it stutters and freezes for seconds, works for some some seconds, stutters again etc. Reboots don't help and factory reset neither. But here the Bluetooth works fine. All the devices mentioned above show without problems.

So it seems like I can pick only one of the two: either I can use the phone to track sports and sleep or I can use it for general purpose like social media, browsing and games but not both at the same time.

It's a bit bizarre - how can a Bluetooth operation be so heavily dependent on software? And why would Samsung stock firmware be worse on using Samsung hardware Bluetooth than Cyanogenmod?

Two most frustrating things with HTC VIVE that would be dead easy to fix: Sounds and restarts.

For some silly reason SteamVR games use the default sound device and then there's a setting where the SteamVR can change the default when it starts and change again when it exits. The right way to do this would be to just let user define that a certain device is always used for VR games, period. No need to change the default audio device for non-VR apps.

Another, related, source of annoyance is that you can't reboot the headset or SteamVR without taking the headset off. Considering reboot is the easiest way to fix, say, the missing sounds, this should be a no-brainer. In general, all the settings you'd want to touch during a VR experience are accessible only outside the VR. The whole SteamVR Settings menu should be available as is inside the VR.

When using eyeglasses putting helmet on and off is a multi-stage process involving removing grease and calibrating the position, so having to do it several times almost every time you use it at all is crappy design.

The fellow who makes ME look like a cynical playground-snarling pessimist - Peter Diamandis - offers up “Why the World Is Better Than You Think in 10 Powerful Charts.”  Do we have lots of problems to solve? Some of them perilous to the planet and our kids? Sure! But one of the worst of our problems is snarling cynics who refuse to look at the good news.  And conclude that problems CAN be solved!  Because some have been.

Living in the cyberpunk age:

> Just hours after Prime Minister Recep Tayyip Erdogan threatened to "root out" Twitter, graffiti has been popping up around Istanbul with two IP addresses anyone can use to circumvent the government's ban. The two numbers — 8.8.8.8. and 8.8.4.4. — refer to Google's Public DNS, which can be easily utilized to maintain access to Twitter.

"FAO on julkaissut raportteja, jossa kotieläintuotannon kasvihuonepäästöt nimetään yhdeksi merkittävimmistä kasvihuonekaasujen lähteistä. Typen oksidit ja metaani ovat hiilidioksidia voimakkaampia kasvihuonekaasuja ja niitä syntyy merkittäviä määriä karjan kasvatuksen sivutuotteina."

"Ministeri Tiilikainen huomauttaa, että Suomen pellot käyvät erityisen hyvin rehuheinän tuotantoon, minkä vuoksi karjan kasvatus on täällä luontevaa."

Ministeri puhuu vähän niinku aidanseipäistä... Tässä olisi ollut ministerillä hyvä paikka tehdä PR:ää yhdelle kovasti nousussa olevista suomalaisista keksinnöistä. Mutta ei. Ei kepulainen voi puffata vientituotetta jos se on liian uusi keksintö.

> If you follow social-science news, maybe you saw the headlines recently: “Conservative political beliefs not linked to psychotic traits, as study claimed,” noted Retraction Watch, for example. As the site explained, four political science and psychology papers published since 2010 have now been corrected for wrongly implying a positive correlation between psychoticism (a trait that isn’t what it sounds like — we’ll get to that) and conservatism. What the researchers should have reported, it turned out, was an inverse correlation: The higher someone rates for psychoticism, the more likely they are to be liberal. There was an error in the way the researchers coded and interpreted their data. [...]

> If you dig deeper and talk to the people who were actually involved, though, what emerges is a frustrating, occasionally bizarre story of scientific dysfunction. And while this is by no means one of the biggest errors to have made its way into the social-science literature, it’s a useful cautionary tale in what happens when the norms social scientists are frantically trying to establish — replicability, openness, and data-sharing — are ignored. [...]

> Hatemi, whose primary research interest is in how political ideology intersects with biology and genetics, was informed three years earlier, in July of 2012, of exactly what he and his colleagues had gotten wrong. That was when Colin DeYoung, a University of Minnesota personality psychologist, wrote him an email on behalf of DeYoung’s then-grad student, Ludeke, who had discovered the errors (Ludeke now works at the University of Southern Denmark). Emails provided to Science of Us, and conversations with all four researchers, show that in addition to suggesting to Hatemi and later Verhulst exactly what they had gotten wrong, DeYoung and Ludeke repeatedly asked for the raw data that would have allowed them to definitively demonstrate the error — and were repeatedly rebuffed in their attempts to attain it (Hatemi and Verhulst tell a different version of the data-sharing side of the story, which we’ll get to). After being informed of their error, Verhulst and Hatemi proceeded to publish still another paper containing that error, in PLOS One in 2015 — despite the fact that Ludeke, in the course of anonymously reviewing the manuscript that would become that paper, pointed it out once again.
“This guy comes up — and I didn’t even recognize him at the time — and says, You tried to destroy my dissertation and I’m going to get you.”

"Like clockwork, the conservatives who up until yesterday were all about “Blue Lives Matter” turned on police because of these comments. According to the president of Open Carry Texas C.J. Grisham, officers should be fired for complaining about his right to carry an AR-15 in public."

As the Open Carry narrative goes, the police should somehow be able to magically tell good guys carrying assault weapons from bad guys carrying them. But in reality civilians with assault weapons all look like civilians with assault weapons, so in a scene of mass shooting police had to spend significant time tracking down every open carry person. If the only person carrying rifle openly would have been the mass shooter, more officers might be still alive.
Open Carry had an opportunity to justify its existence - and it failed on every conceivable level.
