App makers need to stop assuming they can solve the security problem. They always need to break the veil of their own internal firewalls to gain speed. THey need to assume they will make a mistake. Meanwhile yawning right in front of them is the OS level Sandbox tools (e.g. on macs a DTRACE derivative) that allows the entite process and every child process to live insode a resource restricted firewall and possible even a chroot jail. Limit what ports or what filesystems or what other OS level resource the app can have and the damage it can do if it goes rogue is sharply limited.
these are really easy to do! they are built into OSX and Linux (maybe windows too? don't know) and they don't seem to affect performance. So why don't apps use these??
One could offer a small guaranteed income and if you want more then a guaranteed job as well. It doesn't have to be either-or.
As for meaning full work the Depression era found many meaningful jobs. Every time I visit an older park I'm so grateful for the lasting staircases and bridges that were hewn into the walls of canyons for me to walk through. We don't have that scale of free labor these days. I'm sure it was hard work but it was meaningful and lasting. Many people were employed as artists and not only made epic frescos and such that we still have today but also produced temporary art like theater for the desperately poor folks of the depression. It was morale boosting and reminded people we are a society that can come together. It had great value to defining US culture. It was also a time when a lot of new ideas got explored too. Even mathematical functions were enumerated and tabulated (before computers) so that people could knwo the zeros of the hypergeometric series functions for my gaussian quadrature integrals needed to compute the amount of concrete needed for hoover damn or the stress on an airplane wing.
Lots of meaningful work from blue-collar to academian occured in the depression era jobs programs.
Paying one person to dig a hole and another for fill it back in is unlikely to be what people mean by gaurenteed jobs.
In fact I would argue that compulsory public service is really a good thing for citizens. I certainly volunteer lots of time to causes because I can see the impact it has on my community. That impact makes me feel good inside. But it also binds me to my community too which is a good thing.
Finally, if you study the Gini index and consider which countries have the largest economic mobility (Do you earn a different wage than your father did?) then you see that countries with good safety nets actually have more economic mobility than those without. I would guess this is because people willing to take risks can achieve more, but they won't take them if there's a chance of losing everything. Thus just knowing there's a net helps even if you never need it.
If they didn't put any cover at all on it, it should also have the same unbreakable properties. Or if the screen cover were just cellophane or plexiglass. Glass is used in large part because it is scratch resistant, chemical resistant, and it can be thin for less optical distortion. I've heard nothing about it's other relevant properties.

well yes I think that's what I said in other terms. the representational format (as you called "x y z t") verus the pures scaling format (0,1,2,3,4..). the limit of 8 on the divisional algebras makes this special for the representational one.
My first thought is what does ordering out of state mean? The fiber they own, the Right-a-ways they own, any contractual monoplies they own and existing service contracts they own are property with value. Will they be able to sell these assets? If not it's a seizure of private property. Perhaps they will be allowed to continue service providing just not solicit new bussiness? Perhaps they will be allowed to lease these to another service provider? What I might guess is that they spin off a company called "not-Charter" and then sell or lease these assets to this wholly separate company. A holding company is created to hold both Charter and "not-charter" so one company now owns both companies (like Alphabet). Municipalities might try to fit to edge into this but how? not-charter has a competitive advantage of the customer base and existing lines. Municipalities might try to lease the lines but then they are just leasing charter stuff. They could start building out their own but things like right-aways on poles and properties will be a difficult thicket. Witness how Google fiber got screwed out of space on poles and conduits because they were not a registered telecom or lacked monopoly grants. Ironically the thicket of regulations that might seem like limits of cable companies are lobbied for by these companies to create entry barriers. THey like paying for rights of way because it denies others. There are often state wide laws that prohibit a municipality from competing with private enterprise. Municipalities are not allowed to favor one company over another by gifting them anything (anti-donation clauses to avoid graft).
Thus charter exits, and non-charter enters. The customer's ID number on their bills doesn't even change. The profits all go to the holding company and the same share holders as before.
Cuomo moves on to the senate, and then charter donates to the campaign for his replacement. three years from Now charter buys out "non-charter".
Right answer but wrong rationale for getting to the answer. Companies are never purchased for their stock market market cap. They are purchased because they company has some value, usually earnings capacity. A good rule of thumb is that the selling price of a value-oriented company (as opposed to a growth stock) is that about 10x it's earnings. that is the payback period (ignoring net present value) is about ten years. If the company has growth potential then the price should be higher. Thus to take an example, if the price to earnings ratio of a growing company is 16 then, it's also reasonable to pay at least 16 fold it's earnings.
As it turns out that means it's value to you happens to be roughly the market cap plus a premium because the company probably has synergy for you making it worth more to you than to anyone else.
And conveniently, paying more than the stock price is what is required to induce at least half the people to sell you their shares.
You might wonder why it turns out to be so convenient that the market cap happens to be the purchase value of the company. And the answer is, to people who invest based on fundamentals that is how they decide to invest. And consequently the price to earnings ratio of a company tends to track the market cap in just that way. 10 fold P/E for an established profitable company and higher multiples for companies with either higher profits or higher expected growth is pretty normal (well not lately, but over time).
So yes you got to the right answer. But the reason for it is not that stock value-- what people paid for that stokc initially-- is the market cap. When the price declines 119B did not get lost because it was never paid in the first place. And after the sale of a company, the value of that company should rise if it was a good investment so the new owners will also have paid less than the future market cap would be.
point is no one paid the market cap on a growing stock it's a fiction. (now on a failing company that's different).
Without having to understand the physics or worry if it's right or not there is an important fact to be gleaned for computer scientists here. Specifically, we won't have a strong need to ever build SIMD systems wider than 8 (well maybe 16). There might be advantages for parallelism beyond that but they are merely scaling advantages not representational advantages.
That is to say, we currently handle 4 wide floats efficiently in SIMD systems. That's not an accident. Systems like Silicon Graphics were specially designed for exactly the purpose of efficient 4x4 matrix multiplication to handle quaternion graphics. Four is the essential number needed to make the atomic unit of all those transactions be the quaternion size. It makes everything else easier if you are not having to do bookkeepping on the data representation of the 4-vectors.
One might have thought that well, make an 8 then someone will want a 16 then a 32. So there's nothing special about 8. But this says indeed there is something special about 8. It's the largest size you really need to worry about the bookkeeping on. It's the largest atomic unit most algebras will ever need to treat.
You could scale beyond that but you will want to make sure that the most efficient ops can work on 8-vectors in whatever designs you consider in the future. it's special.
And microcode desginers will also want to make 8-ops special as well. Page boundaries should be multiples of 32= (8*float) etc...
For large companies the notion of a market cap is fiction. If one defines market cap as shares outstanding times market price this number has no bearing on the sale value of the shares. Any attempt to sell a trillion dollars of stock at once would force the price to fall in the process of selling it. At that level the last shares might not even find a buyer at any positive price. Thus the market cap would be massively greater than the realizable market trade.
Saying the market cap dropped by 119 billion is equally gibberish.
If you disagree then you need to also realize that no one ever paid the market cap for all the outstanding stock. Most of it was bought at Lower prices. The integrated area of price by share histogram is far less than the market cap.
Hmmm.... don't know enough orbital mechanics to argue but getting heavier sattelites 8 times further away seems like it might take a much larger rocket than the space-X one. So is there much to compare here?
Precisely wrong. First you are right that no one would buy an nonmaintaiable IOT device but they would buy ones that the manufacturers promised to keep updated. You could do that now of course but people complain about the Apple tax or similar. But Apple routers and Apple TV are trivial to update because they do it via the attached computer. So do things like chrome computers and fire sticks.
Or you could contract with a third party if you dare.
The key point is that once someone is paying for it then it gets done.
have teams compete to topple them as fast as they can, any way they can. Like a reality TV show. Do you want the 20 pounds of C4 or the blow torch. Maybe use the monster trucks from Idiocracy's Rehabilitation night. You'd make money.

Las Vegas New Mexico was developed in 3 waves. First the spanish settlements on the farmlands west of the river. (1830s) The streets here have spanish surnames and the blocks are not rectangular or uniform. Then the Railiroad era (1880s) where the highlands to the west of the river were settled. This has very rectangular blocks and all the streets have names like "Washington" or numbered avenues. And finally the freeway and strip mall era of development further to the west has long dead straight boulevards.
Las Vegas was established in 1835 after a group of settlers received a land grant from the Mexican government. The town was laid out in the traditional Spanish Colonial style, with a central plaza surrounded by buildings which could serve as fortifications in case of attack. Las Vegas soon prospered as a stop on the Santa Fe Trail. During the Mexican–American War in 1846, Stephen W. Kearny delivered an address at the Plaza of Las Vegas claiming New Mexico for the United States.
A railroad was constructed to the town in 1880. To maintain control of development rights, it established a station and related development one mile (1.6 km) east of the Plaza, creating a separate, rival New Town, as occurred elsewhere in the Old West. The same competing development occurred in Albuquerque, for instance. During the railroad era Las Vegas boomed, quickly becoming one of the largest cities in the American Southwest. Turn-of-the-century Las Vegas featured all the modern amenities, including an electric street railway,
I recall this being taught in my middle school aerial cartography section of Geography. There's different epochs and influences on city layout. The french and spanish tended to build layouts conformal to landscape features like rivers, foothills, and drainages. The spanish ones always were oriented around a major zocolo plaza with the church at one end. Later American cities were Rectilinear grids. For an extreme case look at Salt Lake city which is paced out by distance from the church at the center.
But this is all well known, the design of cities and it's traceability to the varied possible influences used to be well taught
1. apple doesn't store your passwords on their servers 2. apple has very flexible password generation 3. it works system wide not just as an application with limited privledges. 4. you are not relying on a third party to keep it's OS incompatibilies patched as things break.
I have no idea what continuous monitoring of accounts means.
Password managment is something apple computers already do and sync. Letting a third party like apple be the conduit for your password syncs isn't particularly unnerving. It's no more unnerving than letting 1-password do it.
Unless of course, apple is your employer and insists you use an iphone or a mac computer. In that case you want a different third party.
So it makes sense for apple employees not to be forced to eat their company dogfood in this case. But it probably doesn't mean apple is going away from it's own password management. That works just fine and it's interoperable with other browsers like chrome.
Uber seems to think itself above the law. It's one thing to say "hey that law is bullshit". It might be. But it's not the right of a large corporation to subvert local laws just because they seem to get away from it.
Uber should sell pot from it's vehicles and set up a prostitute order service. What would be the difference? All blue laws are bullshit laws unless of course you like them.
