Comment For all the night shift Tesla owners (Score 2) 20

Sure, you could charge a powerwall and then charge your Tesla at night from that, but there would be a lot of inefficiency in addition to heavy cycling on the powerwall.

But overall it doesn't seem like a compelling sales pitch -- buy solar panels to charge the car that will be at work when the sun is shining.

Maybe the spreadsheet math works financially by offsetting daytime use vs. nighttime charging.

I go through enough of it that I've only had one little packet expire. I usually buy a 5 pack through Amazon and keep the unused stuff in the fridge, which is supposed to extend the life further.

I've thought of vacuum sealing it as well, but since I use enough to not have it expire on me I haven't gone that far, plus its sealed well in Mylar and I expect that exposure to air only accelerates curing and that it would self-cure even in a vacuum.

Another option is silicone tape, but the stretching needed to apply it would be a challenge on small stuff like USB cables.

The small tubes of regular clear silicone caulk (the kind that doesn't use a caulk gun) can be used instead of Sugru in some applications, but it gets kind of messy. If you're willing to waste a certain amount, you can mix cornstarch with regular silicone caulk and get a Sugru-like product that cures faster and is easier to handle, but it's messy to make.

Use of force gets complicated, fast.

In Minnesota, you can use deadly force to stop the commission of a felony in your home.

The felony doesn't have to represent a risk of physical harm, although I think it would help -- shooting a 16 year old kid with your iPad, about the climb out the broken window he came in might be something the DA would consider charging, if only for the DAs own personal PR.

The adult with any kind of a weapon, especially a firearm? They've met the definition of a felony right there, plus there is the risk of harm.

I find the worst point with all of them is near the end of the cable where it hits the connector.

If I think a given cable will get used regularly, I now just grab a pack of Sugru and add my own strain relief at that point. I find it helps a lot, but on one cable (and I forget which of the 28934774 cables I own it was...) it just moved the fray point from where it would naturally occur near the connector to the point where the Sugru tapered off.

I think the only other thing a person could do is both add their own silicone strain relief and maybe dunk the cable a few times in dip-it vinyl coating to armor the cable further.

It would be nice if someone would figure out that high-quality cables were desirable and make USB versions of welding cable with thick, high-flex EPDM jackets. I could definitely use a couple of Ethernet cables like this.

I don't know you, but I'd wager you're like me and you and I probably think of this in terms of $24 billion now versus...working.

I think guys like Zuckerberg are just mentally in a different place. They're not in it for the money, they're in it for the rush of running a massive, growing company.

Money isn't even part of the equation, and I'd bet even at the time money and even the act of paying for something wasn't something Zuckerberg even thought about. He just went places and did stuff, his view of money was the company financials, not his personal finances at all.

Comment Re:Tired of this space obsession (Score 2) 90

The way I look at is if the reusable rocket guys get the cost of orbital rockets down to 1/10th of the cost that it is now, lots of options open up. If you can get 10 trips up for the cost of 1 now, suddenly assembling a Mars-distance ship in orbit and all the fuel and supplies to make it happen seems pretty plausible.

We aren't going interstellar without some new physics, but with a much less expensive orbital lift platform, interplanetary starts to look much more within reach even if it is initially limited to Mars or even Mars orbit stations.

Comment Re:So what are these CISSP "cyberwarriors" doing? (Score 1) 89

What I don't get is why joining the NSA isn't something like getting a really well paid job combined with being in the military.

Pay them really well, so well they would have to think 3 times about not joining. Like 4x a similar pay rate that you'd find in a top-tier city for an equivalent job. Make working conditions really nice -- free high-end restaurant quality dining on premises with a room service option for people who wanted to work through a meal hour, super nice office spaces, the whole experience more "hotel" than "government office".

But then also kick in the military part -- you join up for a minimum 5 year commitment, you live on campus, your travel off-campus is limited and controlled and there's the understanding that you ARE being watched closely, but do it in an unobtrusive manner, not in a police state manner. But make the housing and lifestyle options more like a country club kind of atmosphere, single family houses, lots of recreational options, private schools for the kids, and lots of activities for spouses and kids, too. Make them stay but make staying so easy they want to stay.

Sure, the whole thing would be expensive, but you'd have a much better chance of containing your secrets. And chances are, buying their loyalty would go a long way to helping and keep the security more velvet glove than rubber glove.

The current thing with all the contractors is a mess and it's a miracle that actual government employees have any loyalty at all.

VMWare used to (and maybe still does?) have a license that said you couldn't use their hypervisor in a hosting environment, at least with the conventional end-user license. This was long enough ago that that at the time the business hosting really meant either multi-tenant http hosting on a single box, or dedicated physical server hosting and there was no openstack or similar competing virtualization system like there is now.

I'm guessing that it was meant to allow VMware to "capture" the added revenue potential that would exist if a hosting company at the time had been able to sell VMware VMs at dedicated hardware pricing. They'd sell you the license to do it, but it wouldn't be the normal end user licensing rate.

Comment Write interleaving? (Score 2) 155

I wonder how the flash is organized. Is it just a question of a single flash chip of varying size, or is it possible that the 128GB model is somehow comprised of 4x 32GB segments which allow write interleaving to happen?

The only other explanation that I can think of would be that 128GB represents a level of density that requires superior flash chips which really are faster, and that 32GB uses older parts that are just plain slower.

Once in office he escalated the war into Laos and Cambodia, with the loss of an additional 22,000 American lives, before finally settling for a peace agreement in 1973 that was within grasp in 1968

1968, the year of the Tet Offensive and the siege at Khe Sanh, which Johnson insisted the US win? The same Johnson who decided not to run for re-election in 1968?

I just don't see a peace agreement in 1968 as being something that would have actually happened, especially after Johnson had stopped the bombing in the north as well.

Maybe if Johnson had *increased* bombing in the north to Linebacker II levels and allowed Westmoreland to go after the Ho Chi Minh trail and NVA bases in Cambodia and Laos he could have negotiated a peace treaty in 1968. But along with all the other political intervention in Viet Nam, Johnson himself seemed to prolong the war in Viet Nam instead of winning it.

That's why I think the psychological or occupational testing would be most informative. The DNA test only describes what the ingredients in the cake mix box are, the psych testing tells you what the cake tastes like.

AFAIK there is no predictive DNA testing for personality or higher level psychological attributes. Hell, they often can't clearly identify genes responsible for some heritable physical illnesses.

Hiring an employee for a job is expensive without DNA testing and as such represents a big financial risk for companies if the hires don't work out. I've talked to people who had to spend *days* taking a battery of psychological tests, physicals, etc to get pretty high level jobs.

Adding in another $2500 doesn't seem to be that big of a deal if the cost to hire an employee is already $25k or more.

The question I guess I'd ask is whether it will actually be useful. Will they actually be able to notice significant improvements in performance? I would think that the psychological and occupational type testing they do now would be 90% of the value.

Comment Re:working to offset expansion of the money supply (Score 1) 401

If this is true, how do you account for the never ending ability to sell Treasuries denominated in US Dollars?

If there was some concerted effort to devalue the US dollar, wouldn't that make it ridiculous to hold Treasuries which paid off in US dollars? There has always been an existential risk associated with this -- the US in theory has always had the ability to sell Treasuries, spend the money and then print money to pay them off, but has never directly done this, or at least not on a scale that deviates from expected monetary or fiscal policy.

Any time there's a significant global financial crisis, Treasuries always seem to become more valuable as people seek to move their money into a perceived safe harbor.

Maybe in the future the US monetary and fiscal policy will erode enough that another currency is seen as a safer harbor, but right now neither the Yuan or the Euro is seen that way, each having their own peculiar problems.
