Disabling shots are irresponsible, unsafe, and ineffective.
......
AND open the shooter up to litigation.
The reality is a disabling shot is not a design goal and a disabling shot does not "stop" the other bad person from returning fire in most cases. No weapon is designed to disable today.....
My personal pet solution to this is portable shields. Too often "peace" officers are taught to fire in defense for fear of their life and limb because they have no "safe" place to stop and assess the situation. A shield not too different from a riot shield should be quickly available, doors of police vehicles should have layers added to protect from ballistic small arms fire. A shield can fold or unroll to be about 1meter by 2 meters. An unroll design could be like a carpenters tape where it has a curve and snaps straight but rolls up. Folding designs are obvious and many. Storage can be in or on the deck of the british boot, on the door or behind the seat. Body armor is nice but less effective in many situations.
It's called 'motivated reasoning', but I doubt these idiots have ever heard of it.
Must be a conservative state, because this peculiar strain of stupidity is generally right-wing in nature. It's all about me! me!! me!! and screw the consequences, especially for the environment, our grandkids, or poor people.
Someone is winging it here. Right-wing left-wing it is necessary to read the 400+ pages.
I am only half way into this and it carves out an agenda ignoring any dialogue. Many of the statements of fact are the current conclusions of science in progress. As works in progress the conclusions should not be so boldly presented as fact. This alone will cause people that know or think they know to reject the agenda.
Omitted in this is a solid anchor to mathematics which is covered by others. There is a bit of hand waving about iterative modeling and CO2 cycles, weather and more but after discussing iterative modeling some conclusions become fact.
I happen to be old enough to have been taught "geosynclinal theory of mountain building" as if it was fact. Yet in the afternoon of my final exam I sat in a seminar by J. Tuzo Wilson and some of his students on Plate Technics. I am also old enough to recall when 1inch was defined as 2.54cm EXACTLY and the difference between the old and new can matter.
An old boss of mine (in Wyoming) kept a cartoon behind clear plastic on his desk. It had one man with a gift package labeled "Truth"... the next panel had the same character with a gift package labeled "New Truth". Stuff changes....
There is an interesting management problem that may apply to this. In an exercise teams are given topics to advocate for and against. Then the team that "wins" gets to debate another team up a ladder. The observation and point of the exercise is that as an agenda moved up through the process the position gets less and less flexible. In as little as three cycles some "managers" in this class got so invested in the position they were given that fists get brandished.
The further folk get from the sciences and more invested they get with a position the sillier they can appear to someone looking at it with the eyes of a child.
Watch the old and new Cosmos -- Neil deGrasse Tyson is MUCH more invested in the same positions that Carl Sagan was. Neil transforms conclusions into facts. Conclusions that I agree with but facts.... no.... the "New Truth" beckons tomorrow.
Enough rambling. The US coal and natural gas resources are large. Ignore this and people will die of heat or cold or lack of water (pumps, desalination). Other nations will be happy and aggressive in their exploitation of fossil energy and climate will be impacted no matter what this 400+ page document authors think they know. I know that some of the computer codes involved use "PI=3.14" and iterate for months on many cores to get a result to 19 places to the right of the dp.
The software in particle physics is almost exclusively C++ and/or Python.
Not so long ago, I talked to a guy whose software was mostly Fortran, with Python as a glue. Apparently the FFI on both ends is good enough that hooking this up is no less complicated than it is with C. That was fluid dynamics.
Among other things, they used Python for unit tests...
The interesting bit about tossing Python in the mix is Python is a rich collection of C, C++ and other code. The interpreter is only a small bit of what runs in most cases. Time after time when some interesting bit of Python was found to be a hot spot it would be coded in C (or any language) with the correct link-to-it bits to to cool off the hot spot. As long as the linking bits are correct any compiler can be used as well. Consider that those that find clang.llvm to be a winner over gcc can use the compiler that is the bake-off winner (there can be large differences).
This relentless hot spot removal by the Python community has greatly increased the value. Even R bindings exist.
FORTRAN, Fortran and fortran all have clear regions where symbolic math can rule. Math types have gotten very good at correct symbolic transformations and machines can automate the transformations. For example the compiler can discover a constant expression and evaluate it once inserting the answer into the code. If you run the program 10,000 times on 5000 machines this constant evaluation by the compiler takes time Tr=Tc/(10000*5000) and at runtime has an answer latency of near zero.
However... One implication here is that Java has been deployed on a bazillion devices and permissively marketed.
Now I see an attempt get that JavaHorse back into the barn... But wait that stallion has made my mare pregnant without my permission and Oracle now wishes to claim ownership of the colt but dismissed responsibility for the foal.
To call it Java requires testing the virtual machine. My guess is none of the licensed Java ports identified these libraries as special copyright material and simply permitted them to be included.
i.e. there have been lapses at Sun and Oracle over time where this can be demonstrated. Most importantly any of the products that depend on the big pile of java poo in question directly or indirectly are in violation and failure to protect "Java" in these cases keeps the horse out of the barn. Oracle needs to litigate many many more....
If there are contracts out there that notice libraries and make no distinction and include them all then it can quickly become an all or nothing game. i.e. if they claim all but only own a little bit then no organization could discover the truth in this big pile of poo.
One subtle turn is the tiered hardware and use layers to all this. Java had no restriction on many classes of biger machines. Later the mobile thing was introduced but mobile devices today have more power than "non-mobile" machines. Mobility is slippery too. The older mobile phones were bigger and heavier than many desktop devices (look at the Apple Mac Mini). If I can run java on it then phones are little different. Mobility of many Solaris machines in ships and aircraft come to mind.
Next is the way java is installed. If the installer uses Java before the EULA then where does the EULA live in the sequence of gates, Oh wait it is out of the barn.
Quantum RNG based on off-the-shelf flash memory. It's not very fast (up to 10kbit/s), but it's quite simple and since you have flash memory in close to every device, it's probably a lot cheaper to do than using optical sensors.
This is interesting but to get the bits from flash you do not have them for other things.
A camera because of the size of the array and speed is interesting as a source of entropy in a system. Also they are not alike so it is very hard to model a camera and generate the same result.
Part of the news here is that the crypto folk are worried that a TLA got in bed with a five letter company and biased the built in sparkling new RNG instruction hardware and silicon magic in ways that they like.
Add some additional entropy and mix it in then the TLAs of the world have a more difficult path.
This is not exactly LavaRand or aquarium bubbles but the very fast part has value.
You know that this is not just silly news images and sound bites generated by news outlets with agenda.
This is bigger, blatant and outright corruption.
The astounding thing in Florida was how close it was. Neither side contests the vast majority of ballots cast in Florida. In this case the vast majority of ballots are in question.
The game in Florida was how well the machines mobalized the historic non-voters. One hint was the android/iphone application that Democratic canvassers had. They could walk up to a doorstep and with a click connect to a data base that told them if the occupant(s) were registered and for what party and if they had voted.
A democratic canvasser might pass a republican home and knock on a democratic home and get that vote out often providing transportation portal to portal on election day. A lot of energy went into mail in ballots.
Some of these canvassing groups were funded by federal funds but had clear agenda: racial, social, age based, union based and political. Agenda that were well within the law as it stands today since most were never put on the record.
The old phrase "Birds of a feather flock together." applies here those that recruit recruit within their comfort zone. Some of this is good, some bad, some can be made to sound good, some can be made to sound bad.
Pay attention... There is an electoral college end run in progress. Again within the law but enough change to upset the close balance that we now expect to see.
As for organizations providing rides portal to portal for voters there is no evidence for multiple stop fraud but the same vehicle does make multiple stops and it is unclear if the occupants are different or the same. This lack of clarity invites FUD that feeds voter ID laws. A better solution IMO is the finger in ink solution that we see on TV and in the US it could be UV ink that makes no statement at the grocery store or other public place.
Well he made a tweet to the effect that none of his ideas had been pursued as patentable and none had been patented.
He also said they have and own all the code he wrote (note the past tense).
There is a tangle here if Zenimax prevails because it implies that no programmer can move from one job to another.
To protect himself he would also have to snapshot any and all revision control systems containing code he worked on (as protection). That however is specifically prohibited.....
To prosecute an honest violation Zenimax must disclose their magic and discover code inside the new company.
OR Zenimax needs to continue to pay his salary for a GOSH DARN LONG TIME. A gosh darn long time could be a lifetime.... in the way Mickey Mouse has a lifetime of protection. His heirs and their heirs would continue to see a cash flow indexed by inflation, seniority etc,,,,
An app that would disable the phone if it's moving at more than 20 KM/H.
How does the app know you are driving in contrast to being a passenger?
I would rather most of my passengers talk on a phone than insist that I pay attention to them while I am driving. Some exceptions are the rare individual that can read a map and give directions. So rare I bought a GPS nav device.
Like casinos in Nevada that mint their own silver dollar size tokens and gaming chips it may make sense for closed electronic transaction systems.
Parents and scholarships might make deposits to the account of a student. Time payments to ensure a meal ticket or rent budget not be blown in a weekend might be facilitated.
I'm not clear what point you were trying to make here, but; Your landlord will always retain a key to your apartment. If it's a large enough building, the maintenance crew will have keys as well.
By doing so they assume a liability and a large one at that. In many situations they MUST give fair notice and only enter announced or in a physical emergency... gas leak, water leak....
Most apartments have enacted astounding checks and visit protocols (witness and supervisor). Not to mention lock boxes for keys.
Changing a lock is interesting because previous tenants may have been careless or be nefarious. A number of rape and assault cases has put serious writing on the wall as well.
An internal dead bolt and darn fine chain lock makes a lot of sense.
I think in most cases the flow itself would keep bubbles in check. Bubbles move at a fixed speed up a liquid. As long as the liquid is moving faster than that speed through the siphon, bubbles shouldn't be an issue.
But I don't know the dynamics of what happens if an air pocket manages to form at the top. It may or may not dissipate on its own. Or it may grow, slowing and eventually stopping the siphon action.
Folks with aquariums know about bubbles.
Since flow is partly a function of the cross section flowing a bubble at the top of a siphon reduces the flow. It may be possible to have a small pipe on the top and a longer but smaller siphon in a position to pull from the top and drain the bubble.
The most interesting siphon is the inverted siphon. Used by the Romans -- this was quite the engineering effort of the age.
and a straw with three holes in it might work as a siphon, depending on the size of the third hole (and other related factors such as the viscosity of air)
Add location to this as well.
If the third opening was under water on the head end no problem.
If the third opening was on the down stream end it could limit flow volume by admitting some air but note that when the location of the bottom end extends more than about 32 feet the weight of water tends to pull a vacuum and perhaps trigger harmonic hammering and cavitation like actions.
Some big water systems do use siphons. I wonder if they have a pump and other tricks to eliminate bubbles that might limit flow over hill and dale.
In a darn fine vacuum water would boil and the siphon would fill with water vapor and stop.
As others above indicated.... you need both. As you minimize both to zero you get no siphon action. That is something Bill Nye the Science Guy could demonstrate if he ever got a free ride to the ISS.
At some point I want to believe some of these abuses will open the door to testing of time dilation drugs that could let heinous criminals server 1,000 year sentences.
There are many issues but I just wish that the likes of Mamazon would get it that just because I bought a watch last week that I want to buy another every three days for six months (and counting).
A couple years back there was a plug in that would randomly visit sites and often blindly follow links so a browser history would have a massive pile of deniability. It seems to me a similar obfuscation plan is in order.
The Western world decided to shift from a growth system, where women bear and raise children and the able bodied population slowly increases, to a system where the women enter the work force and children are few in number. If you measure it in years, they did this quite a long time ago. If you measure it in generations, it's only been a couple.
This had the consequence of.......snip....
More accurate than most/. stuff. With the move of women into the workforce we have seen a growing reliance on two incomes to sustain a life style. This has fueled the housing bubble and has removed the ability of a second job as a possible safety net.
Two income cash flow is twice as likely to encounter a lay off or other market driven contraction causing the family planning to fall in the stinker.
Women I know work for status, child care, home cleaning services and in the end get nothing but guilt and disconnected home lives for their efforts. To say nothing about their ability to retire in the way they would like.
This shift is a large and ugly unseen consequence of this "movement".
This will eventually sort itself out in ways I cannot predict. By keeping our eyes open we might make a better world but it is not a given.
Yet another reason to be Anonymous in all things. This is really smarmy and needs to be investigated.
A more fruitful rant might be: To leave feedback at FB:
"Auto play on mobile is just WRONG. Mobile bandwidth is expensive and also costs astounding amounts of battery life. Just because google+ is worse does not make it fine. G+ is disabled on my device FB is next."
I am not thrilled that this is considered a good idea. In principle I suppose you _can_ learn to program on a Chromebook, but only in a very limited way. If this is the wave of the future in education, some thought needs to go into how to design a programming curriculum that can work with these devices.
Not only can but many folk at Google do exactly that. They interact with the cloud of compute servers and VMs to their hearts content. It is not necessary but it is possible to set a Chromebook in developer mode and do the rare odd bit that cannot be done in their cloud. Schools could provide a modest cloud server set of student resources inside a school VPN and have a lot of control.
The point is that not only can you but this is solved at Google and with some modest education of the teachers is easy.
Where did you see that it was Novec 649? There are a whole bunch of different 'Novec' engineered fluids... They could be referring to Novec 1230, which is a fire suppression fluid [mentioned in TFS]...that one doesn't seem very healthy to be around.
SWAG... scientific wild ass guess. I looked at the Novec product line and picked on that I would try first. Note I changed the comment subject to "I wonder" not "I know".
Novec 649 fluid is an advanced heat transfer fluid, balancing customer needs for physical, thermal and electrical properties, with favorable environmental properties. Novec 649 fluid is an effective heat transfer fluid with a boiling point of 49C. Novec 649 fluid is useful in heat transfer particularly where non-flammability or environmental factors are a consideration.
IIRC, the shells will have a guidance system that will allow them to be guided, which is something that they will need if they plan on hitting a moving target – it does take over a minute for the shell to travel 100+ miles – the target will not be in the place where it was when the shell was launched.
And the earth rotates too. Long range gunnery is hard.
The max range of a 155 round is a lot shorter than some are indicating. 16000 yards or about 9 miles for the howitzer. It is necessary to not confuse naval guns with army howitzers. Since I am an Army guy I will not worry about naval guns beyond acknowledging that "guns" have longer range but the max is about 23 miles.
Rail guns are interesting as kinetic weapons. The projectile must be something dense and durable. One guess would be tungsten, or tungsten carbide, depleted uranium perhaps. Depleted uranium amo is commonly jacketed with gliding metal to protect the barrel for sure. I wonder if U has sufficient strength as is for a rail gun acceleration profile.
There is a big gap between modern guns ~25 miles and cruise missiles, both range and cost. Perhaps this is the true goal of a rail gun.
There are fairy glades aplenty in my neighborhood, though I have taken to procuring my wood from a local furniture maker. It dries unromantically in my garage.
Alas, I do not own a fancy CNC router and have learned to make my fiddles by hand, the old way. I will admit to employing a drill press and a band saw in a couple of steps during the process.
Golly you have got to learn to spin a better yarn.;)
I am told (by experts and makers) that the value of a violin goes up exponentially with the addition of the sweet harmony contained in the story.
For goodness sake, for fiddles clean the wood or cut a varnish at one step with a bit of Tennessee whisky or Kentucky moonshine. For a violin audition them in on a warm summer night with a friend or two out at a nearby glenn . Take a photograph of each print on 8.5x11" glossy paper and document the instrument with a paragraph of writing on the back using a goose quill pen and the most permanent india ink you can find.
Americans may eat a lousy bunch of fast,junk food, but at the same time we seem to be living a lot longer than my grandparents generation......snip....
With the existing data this does not seem to hold up. In populations where it can be measured in the US there seems to be at best a two year advantage. That alone might be counted by improvements in pneumonia treatment.
Now the obese generation in their 40s +/- may prove an entirely different set of complications and medical issues. Perhaps the push to eliminate tobacco will balance the scales but obesity is going to hammer quality of life in old age metrics.

>A straw with a hole in it cannot siphon.
A straw has two holes in it.
A straw with only one hole can't siphon.
But it is just one hole open from top to bottom.
A bendy straw could be used as a siphon.
In a darn fine vacuum water would boil and the siphon
would fill with water vapor and stop.
As others above indicated.... you need both.
As you minimize both to zero you get no siphon action.
That is something Bill Nye the Science Guy could demonstrate
if he ever got a free ride to the ISS.
At some point I want to believe some of these abuses will open the
door to testing of time dilation drugs that could let heinous criminals
server 1,000 year sentences.
There are many issues but I just wish that the likes of Mamazon would get
it that just because I bought a watch last week that I want to buy another
every three days for six months (and counting).
A couple years back there was a plug in that would randomly
visit sites and often blindly follow links so a browser history
would have a massive pile of deniability. It seems to me
a similar obfuscation plan is in order.
The Western world decided to shift from a growth system, where women bear and raise children and the able bodied population slowly increases, to a system where the women enter the work force and children are few in number. If you measure it in years, they did this quite a long time ago. If you measure it in generations, it's only been a couple.
This had the consequence of .......snip....
More accurate than most /. stuff.
With the move of women into the workforce we have seen
a growing reliance on two incomes to sustain a life style.
This has fueled the housing bubble and has removed the ability
of a second job as a possible safety net.
Two income cash flow is twice as likely to encounter a lay off
or other market driven contraction causing the family planning
to fall in the stinker.
Women I know work for status, child care, home cleaning services
and in the end get nothing but guilt and disconnected home lives
for their efforts. To say nothing about their ability to retire in
the way they would like.
This shift is a large and ugly unseen consequence of this "movement".
This will eventually sort itself out in ways I cannot predict. By keeping our
eyes open we might make a better world but it is not a given.
Yet another reason to be Anonymous in all things.
This is really smarmy and needs to be investigated.
A more fruitful rant might be:
To leave feedback at FB:
"Auto play on mobile is just WRONG.
Mobile bandwidth is expensive and also
costs astounding amounts of battery life.
Just because google+ is worse does not make
it fine. G+ is disabled on my device FB is next."
I am not thrilled that this is considered a good idea. In principle I suppose you _can_ learn to program on a Chromebook, but only in a very limited way. If this is the wave of the future in education, some thought needs to go into how to design a programming curriculum that can work with these devices.
Not only can but many folk at Google do exactly that.
They interact with the cloud of compute servers and VMs to their hearts content.
It is not necessary but it is possible to set a Chromebook in developer mode
and do the rare odd bit that cannot be done in their cloud. Schools could provide
a modest cloud server set of student resources inside a school VPN and
have a lot of control.
The point is that not only can you but this is solved at Google and with some
modest education of the teachers is easy.
Where did you see that it was Novec 649? There are a whole bunch of different 'Novec' engineered fluids... They could be referring to Novec 1230, which is a fire suppression fluid [mentioned in TFS]...that one doesn't seem very healthy to be around.
SWAG... scientific wild ass guess.
I looked at the Novec product line and picked on that I would try first.
Note I changed the comment subject to "I wonder" not "I know".
3M Novec 649 Engineered Fluid
Novec 649 fluid is an advanced heat transfer fluid, balancing customer needs for physical, thermal and electrical properties, with favorable environmental properties. Novec 649 fluid is an effective heat transfer fluid with a boiling point of 49C. Novec 649 fluid is useful in heat transfer particularly where non-flammability or environmental factors are a consideration.
IIRC, the shells will have a guidance system that will allow them to be guided, which is something that they will need if they plan on hitting a moving target – it does take over a minute for the shell to travel 100+ miles – the target will not be in the place where it was when the shell was launched.
And the earth rotates too. Long range gunnery is hard.
I'll add that I just read that 155mm rounds cost $50,000 each. So it's even cheaper than conventional artillery.
Citation please.
The new GPS radar guided Excalibur perhaps. But no a standard HE round.

The max range of a 155 round is a lot shorter than some are indicating.
16000 yards or about 9 miles for the howitzer. It is necessary to
not confuse naval guns with army howitzers. Since I am an Army guy
I will not worry about naval guns beyond acknowledging that "guns" have
longer range but the max is about 23 miles.
Rail guns are interesting as kinetic weapons. The projectile must be
something dense and durable. One guess would be tungsten, or tungsten carbide, depleted
uranium perhaps. Depleted uranium amo is commonly jacketed with gliding metal to protect
the barrel for sure. I wonder if U has sufficient strength as is for a rail gun acceleration profile.
There is a big gap between modern guns ~25 miles and cruise missiles, both range and cost.
Perhaps this is the true goal of a rail gun.

There are fairy glades aplenty in my neighborhood, though I have taken to procuring my wood from a local furniture maker. It dries unromantically in my garage.
Alas, I do not own a fancy CNC router and have learned to make my fiddles by hand, the old way. I will admit to employing a drill press and a band saw in a couple of steps during the process.
Golly you have got to learn to spin a better yarn. ;)
I am told (by experts and makers) that the value of a violin goes up exponentially
with the addition of the sweet harmony contained in the story.
For goodness sake, for fiddles clean the wood or cut a varnish at one step with
a bit of Tennessee whisky or Kentucky moonshine. For a violin audition
them in on a warm summer night with a friend or two out at a nearby glenn .
Take a photograph of each print on 8.5x11" glossy paper and document the instrument
with a paragraph of writing on the back using a goose quill pen and

Americans may eat a lousy bunch of fast,junk food, but at the same time we seem to be living a lot longer than my grandparents generation. .....snip....
With the existing data this does not seem to hold up. In populations where it can be measured
in the US there seems to be at best a two year advantage. That alone might be counted
by improvements in pneumonia treatment.
Now the obese generation in their 40s +/- may prove an entirely different set of
complications and medical issues. Perhaps the push to eliminate tobacco will
balance the scales but obesity is going to hammer quality of life in old age metrics.
