Define "a lot".

Because most veterans understand that a lot of the senior, politicized brass is kinda wobbly, and given to throwing the junior squids under the bus.

Prime example is the USS Iowa disaster[1], when The Narrative demanded that GMG2 Clayton Hartwig's reputation be sacrificed.

> Anecdotally I haven’t carried cash around in years.

Generally I keep a $40 in the wallet just in case there is a cash-only situation, but that's literally just a backup -- 99% of transactions are on some kind of card.

I see the submitter omitted the end of the original title: "...That Needs to Make a Comeback in 2020". I guess they agree with my sentiment that no, it does not. Even if you ignore the most obvious environmental aspects (the fuel consumption and noise pollution), there is still one other I can think of: even if somebody invented a noiseless anti-gravity drive and the "Mr. Fusion" required to power it, it still wouldn't be a good idea for everyone to be able to simply fly and land anywhere they want...

I don't understand, and couldn't get any information from the article either. If the data are decrypted within the VM, then it is still decrypted at that point, and the host machine can read it.

You can configure it to do that, though. I don't run my hardware in a datacenter (I prefer hosting from home for various reasons) but my server's CPU is set to use the powersave governor.

The purpose of financial statements is to provide value to the users. It should be assumed that assets equal liabilities and equity. There's value in providing a separate liability total, since it gives a snapshot of the financial position of the company, more so than having to derive that from the total liabilities and equity.
There's an entire ecosystem of supported services in GCP (or whatever cloud provided you'd be passing on) that you would have to find an alternative for if you want to co-locate and manage your own physical equipment.

The more logical alternative (without abandoning the cloud entirely) would be to use the cloud provider's dedicated instance functionality (GCP's terminology for this is "sole-tenant nodes"), but these are much more expensive than virtual machine instances, especially if you don't need the capacity of a dedicated node. At some point, you or your bosses are going to be asking if the security is _really_ worth the premium.

SEV-enabled VMs can provide a convenient middle ground -- more protection than just a hosted VM instance, but since you're still sharing physical resources, the cost is closer to a VM than a dedicated instance.

If SEV VMs are considered the equivalent of dedicated instances from a compliance perspective, this could open the door to cloud hosting for a variety of industries who were unable to do shared hosting before. However, that if remains to be seen.

stuff goes wrong with cars all the time. most of it isn't critical to the core function of the machine. cars also undergo routine maintenance where parts are (hopefully) replaced before they fail entirely.
Let me put it a different way. There may exist two different programs that draw the same amount of power through the CPU but have different instructions-per-clock performance. The one with the higher IPC is getting all its extra instructions for free in energy terms.

Look at it another way: if a machine is already in its highest power state, with all cores running, but only executing one thread per core, running another thread on each core may cost almost nothing in terms of energy but could boost instructions retired by a lot.

The marginal cost of each instruction in compressed at the high end of utilization. The first instruction costs a lot, but after you're already running it the best thing you can do for efficiency is take utilization on that machine straight to 100%.
I don't think it's possible to find the information on the pricing of just the ships' hull/superstructure. But from one paper I found the hull of a commercial ship is a pretty considerable expense (about a third of the total cost).[1] I can only imagine that the cost of a USN ship's hull is more expensive.

Then there's this report from Rand: "Equipment costs range from 35 to 57 percent of construction costs for the ship types we analyzed, while material costs range from 11 to 17 percent."[2]. I don't know how much of that exactly is hull/superstructure, but I think we can assume that it's a considerable portion.

Also, building a ship takes a ton of time. So the USN may think it's better to return this ship to the fleet than build a new one.

That ties into another reason that maybe factors in here. It might be worthwhile in the sense that during war the USN will probably not have the time to build a new ship to fight. So giving its technicians experience in bringing a ship back into service might be helpful.

But if you have less intructions to run, you won't turn the machine on in the first place.

And even if the machine is already on, giving it instructions to run will make it change the CPU frequency (DVFS), access the RAM, etc. which does increase its power usage.

There's something darkly funny about people so embarrassed to have a cleaning person in their house, that they create a solution that would put most cleaning people out of a job.

The knowledge workers automate jobs away, leading pundits to say the future for low-skilled workers is to provide boutique services for the upper class. The end being that the upper class is too ashamed to actually consume those services if it means looking at a person...well, that's sort of a delicious irony, isn't it?
The lack of media coverage of the Epstein story is very telling. No reporters appear to be doing any real investigation. What is stopping people from asking basic questions to our government? A simple query to the cia asking if epstien/maxwell/wesner were part of any intelligence operations would be news worthy. Go watch the netflix documentary on epstien. It's four hours long. They discuss epstiens initial arrest and light sentencing, but they fail to include any notion of the reason for it. Acosta said that the light sentence was because Epstein was above his paygrade and belonged to intelligence. How about looking into why John McCain's wife said that everyone knew what Epstein was doing and turn a blind eye. Our intelligence agencies are out of control. The largest story of the decade is being pushed under the rug.

We do High School CompSci without the internet (for our intro course). I do see the internet as a distraction at this level. Forcing young students to think through the logic of a problem and come up with their own solution (no matter how crazy or inefficient it is) has a lot of downstream critical thinking benefits.
great question
> A resolution is difficult. China is a totalitarian country and totalitarianism needs to be fought, but I doubt that a democratic China would be any different when it comes to their claims to the world.

I wonder about this. Why does totalitarianism in a sovereign nation need to be fought? For those of us considering a democratic China...why do we think the country would fare better as a democracy? The Chinese civilisation is goes back thousands of years. Could the system they have now be the cumulative effect of all they have gone through to date? In other words it has evolved and generally serves its people. It may evolve into something else (possibly resembling Western democracies) but it may not. I don't particularly think it has to.
Can you name a company whose products have literally zero problems?

>She had been in living in hiding, most recently in Bradford, N.H., in the mansion where she was arrested, prosecutors said. They said it was located on a 156-acre property that was acquired in an all-cash purchase in December by a limited liability company that concealed the buyer’s identity.

>After her arrest, a private security guard who worked on the property told the F.B.I. that Ms. Maxwell’s brother had hired former British military members to protect her in New Hampshire, the prosecutors said in their filing Monday.

>The guard told the agents that he was given a credit card in the same name as the L.L.C. to make purchases on Ms. Maxwell’s behalf, and said that Ms. Maxwell did not leave the property at all during his time there, according to prosecutors.

I'd imagine the prosecutors were referring to these details. Like you said, I think the author of the article just laid it out in a misleading way.
I often identify a screw or bolt with a scale. I guess if you know that 16 TPI = "D", then you're ok... but in the same place as now.
Security flaw, sometimes may not root in technology side, but politics side.

China is treating everything they own as a politics weapon now. 5G contract is a perfect weapon in this view. Telecom infrastructure is huge, and almost monoplied by the base infrastructure builder due to compatibility issues. Once Huawei finished the 5G base infrastructure, China can coerce UK by attach extra terms for maintaining, upgrading or selling 5G equipments.

China has already used this approach on loans of asia investment bank. The countries which supports HK Security Law coincidentally matches with the countries which receives loans from

Some may still remains to be conspiracy theory: China increased production of hydroxychloroquine, in their reports (http://tn.china-embassy.org/chn/dtxws/t1787078.htm), they already used Chloroquine in treating their patients. However, WHO, FDA and even Lancet banned or announced inefficiency of hydroxychloroquine, and people died from this misinformation. What role did China play remains suspicious and mysterious.
That's fine, but now you need another 999,999,999 solutions. Until they're here and implimented along with this one, we don't have an actual overall solution do we?

Oh wait, no, emissions went up again while we've been talking and getting this ready. So we actually need one billion and three more solutions to get to the same place the original billion would have got is to.

This is the reality of it situation.

Sorry to be so bleak. But I think people (a) think we're making progress, and by any actual measure we are not and (b) think that piecemeal, you-do-you solutions will work, when they haven't for the last 50+ years.

That assumes members of the legislature always vote with their own party, which they don't. Plus, there are usually two houses and the upper house can scrutinize and hold to account the lower house. In the UK it's an appointed (and partially hereditary) upper house, so there's less party discipline (although not none).
This protects against remote rogue employees and intruders.

As for physical attacks, Google is ultra paranoid about physical access to DCs, and I think we can quickly agree that rogue employees and outsiders would have little chance of successful attack given the outrageous (and secret) methods that Google employs. Remember, this is one of the most-attacked organizations in the world, they've had decades (plural) to enact defenses and test them, and a successful attack would cost them over $10 billion - there's a virtually unlimited budget for physical defense. Circa 2020, I'd put Google's physical intrusion defenses up against most military installations.

Also, I once encountered a site where spam+xyz worked for signup but failed validation on the login form. I think it was something important too, like a utility or bank.
Going from a culture where I pair programmed all day and mostly just pulled stories from the backlog, working from home in an org where pairing is less prevalent (but not non-existent), it's taken me time to retrain my personal expectations that it's okay to count work time as time spent thinking about how to solve the problem.

Our media loves to criticize Russia's interference with the president election. They fail to bring up how the CIA interferes with elections abroad. I do not agree with communism but the idea that a communist movement could occur without interference from the CIA is absurd.
The power LED on the sub-base next to my TV bright I couldn't even watch TV as I was squinting. I put about five layers of masking tape over it to dim it enough that I could still see when it was powered, but it didn't light the whole damn room up.

The clock in my bedroom uses an orange display, which I figure is better than one emitting blue light when you're trying to sleep.

I'm not actually sure that's a difference. On the old systems where that philosophy was developed, disk space was at a premium. In fact, IIRC, the lack of space precipitated the need for a modular system of the sort described by the Unix philosophy.

Yeah I don't think the world needs household robots that are disposable. I'd expect them to be a similar investment to a high end car in the interest of a lower total cost of ownership over long timeframes. It would ultimately be very expensive to make wave upon wave of "cheap" high tech landfill fodder.

What I'd like to see is standardized interchangeable parts and configurable software so we can spec robots to their tasks and benefit from reuse of parts and code as much as possible.

How to UseMemo in React
I don't personally limit myself in this way, but I understand. Having personal friendships at work makes it more challenging to make hard business decisions such as switching companies when opportunities present themselves or firing / laying off team members. I've worked with people who are very friendly and pleasant to work with but explicitly avoid any personal relationships so they can use pure cost-benefit analysis in career and company decisions, rather than allowing emotion and sentiment to influence it.

Edit: actually, the most effective person I ever met who did this was someone who _did_ hang out outside work and etc to allow others to form personal bonds with him, but he avoided reciprocal investment in them. This let him take advantage of their empathy while not having any of his own to limit his decision-making. It was a bit sociopathic, but I saw firsthand how much it helped his career.
Oh man that has to be one of the most frustrating things whenever I go somewhere that has the news on...Hell, I saw someone use a twitter thread as a "source" as support for an argument on facebook.

I can tell you there is a huge market for something that works well in the 40-50k range. You are vastly, vastly underestimating this market.

Hotels have a variety of tasks they would love to replace a host of low cost labor with robots with.

Someone in a higher income bracket wouldn’t think twice about that cost if it did significant work. On the other hand, the bar is high (cleaning, folding, picking up -- all are still fairly challenging AI problems, to say nothing of the "business" logic that would go into it).

Then you've got that quality servos are expensive. Some of that can resolved with volume, but not all of it.
