Some of the troubles of slashdot is that lower IDs are a sign of 'worthiness' and Karma is mostly unobservable (capped too); the gamification is limited; If I only had a five digit UID or better yet four, then I'd really be someone.

In the last few months of gestation, mothers will pass some immunity to their babies (through the placenta; Breast milk helps too), but clearly not as much as you think. In part because a baby isn't a direct copy of the mother, everyone's immune systems are different. However, once a baby's immunity system is fully formed (about 6 months after birth), it's important to as best as possible stay on schedule with every recommended vaccination. A strong natural and individual immune response from a vaccine is the best protection, both for the individual and society as a whole.
A common misconception about vaccination is that it prevents infection. Vaccination only trains your own body's immune system to attack a disease after your system has been exposed to it. For some their vaccination wasn't good enough to build an immunity and others might have temporary or lasting immunity system problems. Even vaccinated people can get a disease, but it's generally less frequent and more mild overall.
Babies have to grow some before and other people have actual real problems taking a vaccine ever, those people rely on 'herd immunity'. I'm fairly certain that you too were at least once a baby.
If your Ring camera or doorbell product is stolen at any time after your purchase, Ring will replace the stolen device at no charge to you. This theft protection is not transferable and applies only to the original consumer purchaser. Coverage of this theft protection is limited to one (1) replacement only for each Ring camera or doorbell product that you have purchased. Theft protection does not apply to any products purchased from third party sellers on eBay and other online marketplaces. Any claim based on theft of your Ring camera or doorbell product must be submitted within fifteen (15) days of the theft and include the original sales receipt, and a copy of a police report evidencing that you reported the theft to the police. Failure to report the theft to police voids this theft protection
Fiber is available in places where it's already run, but not generally expanding at the rate which it should. Verizon stopped their roll out about a decade ago and has only expanded in places where municipalities are suing or as a replacement for failing copper lines. Comcast is pushing gigabyte service over it's coax, but has limited fiber roll out if the community insists on it. AT&T is plodding along only in metropolitan areas. Google has went as far as to dig up some test deployments and hasn't moved quickly. Other players aren't entering.
Conspiracy?
Maybe not. 5G is supposed to give multiple gigabyte service to both traditional cellular and home customers, which would solve the 'last mile' hookup costs for home internet service. I suspect that most companies now are spending more money putting 'larger tubes' to the cellular structure, or at least I think they should. However, it could be much more than a decade before cellular tech can really replace fiber-to-the-premise. On some levels we are in a troth between current reality and the future.
If it's such a big consideration, perhaps you could spend, say, 5 minutes looking for them? Best phones with a physical QWERTY keyboard, which shows three phones with an 'old fashioned keyboard' (two blackberries, one motorolla) and notes that the Samsung S8 has a keyboard case option made by the manufacturer. Also there are plenty of small bluetooth keyboards and third party case options, yet I've never seen one 'in the wild'.
Whenever this topic is broached there is always someone who complains about the lack of physical keyboards and claims that it's the option they are willing to switch for, but the reality of it seems different.
"Self Produced" is a misnomer because while many 'broadcasters' do have production departments, few shows are produced fully 'in house'. Scripts are purchased, production companies get contracts and complete movies/series are often sold into distribution. Before becoming the cheesy 'movie of the week', it may have started out as someone's grand idea only to lack the money or attention, if production went well some of them could have ended up with real box office draw. The fact that 'made-for-tv' were exculded was more about which part of the corporate giant released the work, productions often take trips though a couple divisions if not competing companies.
Furthermore the idea of 'limited theatrical release' is now a business model where 'Oscar winnable' films are put in a very limited release just before the end of the year with the idea of using expected nominations to drive ticket sales during awards season.
Unix vs DOS line endings should have always been the 'go to problem check' for a weird error in a Windows to Linux environment, sadly I've seen it in a professional environment dozens of times. Any decent text editor (including those in IDEs) will handle both and resist changing when saving, but notepad had until recently always 'automagically' converted the file to DOS which was the only way to save.
Actually, the difference is that Windows works just fine with the standard UNIX line ending (\n'), but many unix programs will crash if they see a DOS line ending ('\r\n'). I'm guessing that Microsoft simply made sure to preserve the line endings already present in a file (like the regular setting in all better text editors), or changed the default to the UNIX endings, which is already handled in Windows (as best as I know) . In fact a recent article annouces UNIX EOL support in notepad
When you see '^M' at the end of every line in a Linux config file you know that someone edited the file on a Windows system. It's a simple fix (dos2unix), but it can really trip up new developers and sometimes even some 'old pros' on a bad day.
I'd guess that it's more like 10 or so years from the start of a tipping point. By then about 20% of the cars will be electric, at that point gas will start to get cheap (with the removal of 20% of the demand), but banks and investors will stop financing oil projects (which require lots of money just to keep going). In about 20 years gasoline would be very expensive and pull the rest of the car market into full electric.
Today charge times for a 'super charger' will likely surprise you, 80% charge in 40 minutes, fully charged in 75. While much longer than the max of maybe 5 minutes pumping, a 300 mile range is about 5 hours of driving, charging while taking lunch/dinner or sleeping at a hotel will likely become the norm. Even if stopping for 2.5 hours in a 15 hour drive may seem unreasonable for some, I don't think that it will be a real blocker for purchase for most. Especially because most will simply charge overnight at home, so it will actually save time, especially when gas stations become scarce. Also there is 'new tech', Porsche has an upcoming production car which is much quicker to charge and 'air lithium batteries' are being developed.
Gasoline is effectively storage of that energy which creates more pollution to release at the point of use. How much electric varies with some estimates claiming about even on a per gallon, but it surely varies with the quality of the inputs, which includes more than just crude oil, much of it manufactured itself. Add in the industrial pollution, the gas station tanks which usually start to leak after 10 years (even discounting environment, leaking product is a bad), the gas/oil tankers eating diesel and the idea of not depending on a depleting resource, it is hard to imagine a world not better off with electric cars.
However, what is likely the biggest advantage is that electric doesn't care how it's made, as we transition from fossil fuels to renewables to perhaps fusion (it's been 50 years), our cars will be able to use any of them. Disruption of oil from the Middle East, South America or Russia wouldn't send our economy into a tailspin.
Every morning I park what might be my last gasoline engine car near the 'plug in' area at work. However, even though I'm one of the first 10% of the people in the office, both chargers are usually occupied. Unfortunately, I suspect that I'd never really be able to take advantage of the free charging.

I've been thinking about getting a used Tesla next year, once my Honda CRV is paid off. One of the nice things is that beside brakes and tires there is very little maintenance needed for them and the batteries look to be holding up very well. They are expecting 90% capacity at 185,000 miles on average and people with high milage are seeing better results. $35,000 for a 2012 Model S is looking like a good deal, but I'll likely pick up a midrange Model 3
No need to 'miss those days' you can totally get a phone for even less right now. Even a quick search shows newly released 'clones' of the flagship iPhone for $300. If you don't mind tech that's just a few years old, a new battery in an old iPhone for $29 was a great deal and several manufacturers make brand new phones some even consider 'disposable'. Search for 'flip phone' you'll find dozens similar to the Razr. However, at the time it was popular, it wasn't cheap, also like all the phones of it's era it had both a proprietary headset AND charger. Don't forget a charger for the car and another for the office. To me it's just another example of seeing the past though rose colored glasses.
However, what many seem to misunderstand is that phones used to come as part of a 2 year contract, the full unsubsidized prices were much higher. Phone plans now have 'unlimited data/text/voice' often for the same price that used to be for a dozen or so 'prime time' hours. These days they only offer installment plans on full price phones with continuing service; you can only find discounts on new equipment for new service (which is actually a rebate on an installment plan).
The idea that 'everyone thought that the earth was flat 500 years ago' is a myth. The ancient greeks knew that that the world is roughly round; Pythagoras wrote as much in 600 BC. Christopher Columbus was ridiculed because he believed that the world was half the size that most who had studied the subject believed. They were right, if he hadn't run into 'the west indies' rather than India as he planned, the famous explorer would be nothing more than a footnote at best.

Does 'cutting out the middle man' save any money for the consumer? No.
While I pay for Netflix directly, I've bought some subscriptions, simply because it minimizes the steps to cancel once I'm done catching up on content (I'm looking at you, 'AMC Premier'). It also reduces my exposure to credit card fraud because , a single bill is easier to explore and I'm fairly certain that they cannot simply raise a price without an explict opt in on the new rate.
OS/2 was IBM's official successor to PC-DOS and originally completed against Windows 3.1, 95 until it was fully supplanted by Windows NT (Linux distributions also). "OS/2" was the name, the last version produced by IBM was 4.52 in 2001, however, in 2017 they licensed eComStation to create an updated version.
The thing that struck me the most was the number of 'thieves'. While 'porch pirates' are a real thing, they aren't so common that one guy or even a couple of them could in short order have so many packages lost to them.
Call me crazy, but for $100,000, I'd drink tea for a year. As for the smartphone ban, a cellular laptop and a flip phone would work just as well overall. I would miss a couple of iPhone apps, but a chromebook can run android apps, so that might work.
While it's true that most fiber installations reuse the existing coax to provide TV signal and data to a more centrally located router in the home from the ONT box (Optical Network Terminal) which is usually located on an outside wall, that isn't the only way to set it up. If you don't need 'regular TV', have an CAT 6 or better ethernet network which can reach and ask for it, you can wire right straight from the access point.
Comcast (aka Xfinity) has pure coax back at least the neighborhood level, which is 'shared' between everyone on the service loop.
After several years on Xfinity with a TV package, I recently swapped back to FIOS for the near 1 Gb connection as part of becoming a 'streaming only' media consumer, which saved me a chunk of money. While there was a couple of outages which were fixed by restarting or resetting by customer service, eventually they sent out a tech fixed my cable by changing a couple of connectors. However, I never had much trouble after buying my own 'cable modem' about that same time, so I'm not really sure what did it.
I have no hate for Comcast, but every time I looked it seemed that the service was more expensive than before. However, I have no illusions that past my two year guarantee, Verizon won't increase the rate even above the current 'full price', it's the nature of the beast. I'm just glad I have two services to fight for my business rather than a largely unregulated monopoly as many do. In many places the electric grid is a highly regulated shared service while you buy power from company which you can easily switch. I would argue that Internet service is on par with other utilities and could use the same treatment, in fact due to the nature of IP, such a plan could likely be a good idea.
While I'm on the subject, at first I only had near the full 1 Gb connection when directly wired to the ONT using my son's Alienware laptop, even the Verizon tech's tablet didn't show the full speed. My personal router (a fairly new Asus ACU88) didn't handle much more than 350 Mb, I bought a NETGEAR Nighthawk X10 AD7200 from which I now get all the service for which I pay.
Even if refineries operate power plants which provide 100% of their needs, which I donâ(TM)t think is true, you donâ(TM)t disprove a single point. The main point is that total power consumption, from any source, wonâ(TM)t likely raise significantly, if at all.
What many (nearly all?) don't take into account is that it takes a considerable about of electric to refine crude oil.

The difference is that NASA isn't paying for the parts per spec, but the complete mission as a whole. Previously projects were designed down to the single integration item by a committee including congressmen and the private contractors (who are paying them). The net result is a system where the parts are broken up and scattered by congressional district. That's how the shuttle boosters (and now the solid rocket portion of the SLS, or whatever they are calling it now) are made in Utah.
The free market is not an American invention; it was created before the first sharp stone was traded for a spot by a warm fire. Likely the only human activities older are warfare and sex.
50,000 jobs weren't all going to be 'new to the company', maybe not even mostly. Surely a number would be high level transfers from other locations, including DC and NY. Executives avoid moving as much as anyone, while some will make the jump to a new city, most will stay 'closer to home' (often family) and resist moving power to a new complex. So there might have been very real internal forces pulling them 'home'.
Also, while Amazon called it a search for HQ2, it's not uncommon for a company to have divisional HQs. The division which would easily be likely to gain its own HQ would be AWS. However, AWS has a growth problem in that many retailers (and some other companies) while they like the platform, don't like adding to a competitor's bottom line. Add to a market cap which is creating its own weather (e.g. disproportionately affecting it) in the stock market and regulators sniffing around a forced breakup and you could understand the wisdom of Amazon doing it on their own terms. So I think that this has always been a search for a home of a spit off AWS and there is also a decent chance that they'll spit into a third company (perhaps software), with a choice of two HQ2s this seems likely.
have a long shot guess that the reason why it took so long is that Amazon will announce both the HQs and the split up at the same time.
Actually, Master/slave is a very bad description of the relationship typically described by it. In most systems the Master does much if not all of the productive work, slaves are generally observers, ready to move into the Master role if needed. Outside of the IT world such a view isn't realistically possible. While some distributed cacheing situations may seem more appropriate, I'd argue that zookeeper is the only use case for the Master/slave terminology, because it does different work than those systems which it supervises.
I had to read that again as well. I'd guess that the F-18 (perhaps modified) is expected to make a sound wave similar to what's been modeled, but only under specific conditions. e.g. diving once already above the speed of sound. This is a survey to see if it's really at an acceptable level.

So I think that this has always been a search for a home of a spit off AWS and there is also a decent chance that they'll spit into a third company (perhaps software), with a choice of two HQ2s this seems likely.
have a long shot guess that the reason why it took so long is that Amazon will announce both the HQs and the split up at the same time.
Actually, Master/slave is a very bad description of the relationship typically described by it. In most systems the Master does much if not all of the productive work, slaves are generally observers, ready to move into the Master role if needed. Outside of the IT world such a view isn't realistically possible. While some distributed cacheing situations may seem more appropriate, I'd argue that zookeeper is the only use case for the Master/slave terminology, because it does different work than those systems which it supervises.
I had to read that again as well. I'd guess that the F-18 (perhaps modified) is expected to make a sound wave similar to what's been modeled, but only under specific conditions. e.g. diving once already above the speed of sound. This is a survey to see if it's really at an acceptable level.
