Amazon search has been increasingly ignoring the input and just barfing out SPAM. Even very specific searches mix in both sponsored and otherwise promoted items to the point where exact matches often are excluded. I went looking for a bicycle chain ring I have previously bought. Multiple exact name searches and variants turned up nothing but SPAM and semi-related bicycle garbage. I figured it was no longer carriered, wrong. Google found it on Amazon and it was still quite actively sold, just not discoverable through Amazon's search.
Screw Bezos.
I keep seeing claims that most of these cities already have laws on the books mandating helmet use for these things, yet I've NEVER seen a helmet on any riders in my area, or on the riders in any of the news reports about their rollout. Perhaps if the companies were liable for the injuries suffered they would find a way to enforce helmet usage.
Sadly that would only be possible if their app was running on a platform that had access to a camera, oh wait...
No, more accurately, Trump won because of the majority of people, who disliked both candidates, a LARGER fraction disliked Trump slightly less than they disliked Clinton. But you know, that whole electoral college BS thing.
When elected, Trump was the most disliked president elect in history. If Clinton had been elected, she would also have been the most disliked president elect in history.
"For a portable device, that means more battery drain. So even if you can run apps a few % faster, you'll only be able to do (roughly) the same amount of work before battery runs empty" Actually no. In the olden days the supply voltage was fixed, leakage current was low resulting in a constant energy per cycle for a given operation. In modern times the supply voltage is carefully adjusted with clock speed. Run the part down at 1V and it might only run at 1 GHz, crank it up to 1.5V and it goes at 2 GHz, but consumes about 4x the power and also has much increased leakage power. Cell phone SOC's go even further these days, containing both low power cores and high performance cores to further scale power savings across a wide range of operating scenarios. The low power core might be half the performance at a given clock rate, but a quarter or less the power. Firmware choices as to which cores to activate and what clock rate to run at can make huge difference net power consumption and perceived speed.
Seriously, why is wearing a badge and uniform automatic immunity to virtually every blatant transgression? Police should be held ot a higher standard, not a very low one. Seeing your fellow brother's in blue headed to the lockup will be more of a wake-up call than hours and hours of training and re-training you not to beat the crap out of, or shoot those you are protecting and serving.
There is a pervasive mindset in CS majors I have run into that all that matters is coding. Far to often they jump right in and start barfing code down without understanding the real application. The result in major rip-up whenever a requirements doc is not bulletproof (and when are they ever?). Training them in school to design an overall approach, mockup the UI, get sign off from customers, then finally code it up would make a lot of projects go faster and better in the long run.
In school this shows up as a mindset of getting through all their CS classes in the fastest, least engaged fashion possible. TA'ing a EE class for CS majors was eye-opening and depressing. Many of them dry lab'ed their work claiming they didn't need to test their solutions (many bits of their assembly code were just wrong).
I don't think that History majors being added in will solve this. I do see a need for CS to mature. Perhaps in another decade or two the churn in languages, frameworks, etc will settle out and they can pull their heads out of their Mountain Dew pile to smell the roses, who knows... I work with a lot of EE's turned coders who got their jobs specifically because pure CS majors struggle when understanding complex RF things being processed in software/firmware cannot be handled by simple function calls. A coder with some RF and math background handles this stuff in stride.
Left out is a comparison of income growth and unemployment rate by degree track. Have those majors seen a huge salary run-up relative to college averages due to this new scarcity? Are key English and History jobs going unfilled? I suspect the answers are No and No, or the article would have headlined with those claims.
The exploding cost of higher education should be a real guy check for students and parents as so whether a desired degree track is worth the money/debt and if it will ever pay off. I believe for many the answer is becoming and emphatic "No".
Computer Science shows very strong growth, Engineering shows modest growth. Given where the economy has been going for the last few decades I would argue that the trends are right in-line with the work force aligning itself with the job opportunities.
Why would insurance companies care? They insure people today at a profit, even motorcycle riders and teenagers that have a ~10x risk over normal car drivers. If autonomous cars come out and prove to be 10x safer, expect that the premiums for it will be ~10x lower, not that they will crank up premiums for normal drivers or lobby to outlaw them. Insurance companies are about profiting by charging a mark-up over your statistical average cost of coverage, not about caring about their customers.
Don't discount the chance that your 10 year old EOL'ed HAL-car may be refused insurance at all due to out of date software that is deemed to no longer be road worthy. If you think hackers won't have fun with finding old zero-days and wreaking havoc across fleets for kicks, then I have some Hillary Clinton emails to sell you.
Autonomous cars need to be 10-100x safer than human drivers to be accepted. It is stupid, but that is what we seem to demand of machines that replace human judgement. Half the selling point in all the propaganda thus far has been how normal drivers are a hazard to themselves, and that the only way to save ourselves from ourselves is to let HAL take over driving duties.
Now it is becoming clearer that its not just having a human driver, but also the basics of speed, margin or error, etc. Achieving the claimed safety improvements is more than just letting HAL take over, rather we need roads with good paint lines, for the cars to drive slower, respect the law, etc.
I have real doubts that the Venn diagram includes overlap between ">10x Safer", and "Not maddening to ride in."
+1. There are tons of hidden environmental costs of normal store fronts as well. Consumers drive there and back, at a cost of $0.50 a mile or so (often ignored by people who go store to store to save a few bucks). Consumers also demand razzle dazzle up to date interiors with poorly insulated glass fronts held at 72F, so lots of frequent renovations for aesthetic reasons and large cooling bills to allow you to drive your SUV from the suburbs to pick up your nick nacks.
Amazon can easily heavily insulate their huge warehouses (more volume per unit area), and can also can sweat out their low end employees to save on cooling bills. Brutal, but also more Eco-friendly. Amazon does not have random schlubs pawing over the merchandise making a modest percentage unsightly and therefor unsaleable.
With all that data in hand, what should we expect as a death rate compared to the current death rate in developed countries? How about pedestrian and cyclist fatality rate estimates? How about operator intervention rates on typical US roads (i.e. crappy poorly maintained and often mismarked)?
All those simulations and miles are just a big round number, I want to know what the scorecard looks like. If these things were near perfect there would be no need for such continued voluminous testing and refining.
This. I was interested in upgrading 6 months ago, but the crypto craze had prices beyond what is reasonable, so I waited. Now I'd rather wait a while longer for the next generation unless there are some sweet discounts (unlikely). 4K at >60 Hz is a big want. I'd also really like to see some unified G-Sync/FreeSync standard come along, preferable without the 2-3x monitor markup.
60 Hz limit in 4K of DP1.2 and HDMI 2.0 have made 4K a real trade-off compared to 1080P, gaming.
There really is some chicken and egg stuff going on between having a card good enough to drive 4K, and having good monitors that can do 100+ Hz at 4K. Even today the Gsync capable screens painfully more expensive than their vanilla counterparts.
In a capitalist system there are never any true shortages, you just have pay what the market demands.
You can't simultaneously gripe about lack of talented candidates while only raising wages 1-2% annually in complete lock step with your competition. If these people are vital for the company to survive they should be paid whatever is needed. After all, that is the argument for inflated CEO pay.
Agreed. It is rather alarming that so much safety critical equipment in a Tesla can be easily software tweaked at will by a company stuck in a startup mindset. OTA updates are great, till they are not. I'd freak out if my car suddenly changes how it responded to the the brake pedal. Using your fleet of installed users as unwitting testers is pretty damn sketchy.
+1. Most semiconductor chips (especially cheap stuff for IOT) use aluminum metallization, while higher end stuff like your CPU likely has at least partial copper metallization if high current/power density is needed. Bond wires are often gold, but aluminum and copper ones are not uncommon either. The total amount of gold in a bunch of bondwires is really really tiny too (15-20 um diameters are the norm, with usually 1mm length, about 6 ng of gold per wire, or $0.0002 of gold per wire).
Most gold plated boards you find these days are ENIPIG which puts down nickel on copper, then uses a process that literally puts 1 atom of gold down on the surface to protect the nickel from oxidizing, and that is its entire purpose. Only edge connectors that need to work over repeated insertions like your GPU's board get gold of any real thickness these days, and even there the amount is pretty darn small.
A theme for appliances is to avoid the luxury models. The volumes are lower, so the the designs are not as well wrung out, repairs are much more expensive, and they are often in designer colors that look out of date sooner.
Get the low end ones with barely any controls in white. They will likely cost half as much, last twice as long, and cost half as much to repair if you need to do so.
WiFi connected anything is a large negative to me these days. It will be unsupported within a year, if not by the day it goes on sale, and is usually a sign of a product trying to distract you from otherwise junk design.

Regulate Nicotine as the addictive non-medicinal drug it is. If it was introduced today it would be lumped in with cocaine, heroin, and marijuana.

A major sign that Linux needs to grow up. It has a Bus Factor problem. I mean the guy can't even go on vacation without causing upheaval.
