How President Nixon Saved/Wrecked the American Space Program

Hartree Re:Hate Nixon (125 comments)

That was in the 68 campaign (i.e. I'm a bit young to remember much of it personally, unlike Watergate and the fall of Saigon). How much effect it really had can be argued. One thing I do know is that even later the Paris talks weren't looking all that promising until at least 1972, and Thieu had to be strongarmed to go along. Whether Johnson/Humphrey could have delivered Thieu to the negotiating table even without interference is a question we'll never know the answer to.

There's plenty of things to dislike about Nixon. He's always been a mixed bag in a lot of ways. Yes, he was a crook. But, some of the diplomacy during his administration may have reduced the chance for nuclear war (détente with the USSR, and the opening with China).

In some ways, his Vietnam policy is similar to Obama's in Iraq. Then it was called Vietnamization, now it's called having the Iraqi's assume responsibility for their security. In the case of Nixon, we have 40 years of history to know it didn't work very well. In 40 years, we'll know a lot more about how Iraq works out.

How President Nixon Saved/Wrecked the American Space Program

Hartree Re:Hate Nixon (125 comments)

All depends on how you define "playing in that sandbox". We had several hundred military advisors there during the 50s. Now, you may be able to say that Truman was also "playing in that sandbox" while it was still French, but you can't say the US wasn't there in more than just casual numbers during Eisenhower's administration.

Now, if you mean standard combat troops, that was the Kennedy administration. But, advisors and intelligence personnel are a nebulous area (a bit like our current anti-gravity personnel in Iraq who in no ways have their "boots on the ground").

How President Nixon Saved/Wrecked the American Space Program

Hartree Re:Hate Nixon (125 comments)

"But.. if I feel like Nixon hating there is always Vietnam"

Which part do you hate him for? Ike and especially Kennedy were already playing in that sandbox. LBJ was the one to get the Tonkin Gulf resolution passed and massively enlarge the commitment of troops.

If it's that you think he lost the war, that was already well underway since the crisis of US public opinion after Tet. The draw down of troops and the cut off of ammunition to South Vietnam were nearly mandated as a result of public opinion and congressional action.

Yes, Nixon increased the bombing campaign and implemented a blockade, but also pursued peace talks with North Vietnam (The agreements which N. Vietnam basically violated when they pushed south.)

I've been appalled by how often when I've heard one of the younger set say that Nixon started the Vietnam War. That's a pretty major failure of history knowledge. I'm hoping that's not what you were thinking.

A Garbage Truck That Would Make Elon Musk Proud

Hartree Re:Engines are more than just for movement: (174 comments)

Sure. Or, just make it a hybrid drive with charging from the grid and have the best of both worlds.

Fire trucks are a small enough part of the vehicles out there to be less of a worry for efficiency. Reliability is a big thing for emergency vehicles.

There are a lot of garbage trucks and other utility type trucks out there that do short range stop and start runs that would probably make a lot bigger difference.

A Garbage Truck That Would Make Elon Musk Proud

Hartree Re:Long distance freight: (174 comments)

I'm quite familiar with intermodal transport. It becomes useful on longer runs. But, being able to just hook in to a powered feed is a lot more flexible.

For intermod, you have to have a truck and driver on either end of the rail link, plus the time to assemble the train, etc. It's quite efficient in a lot of ways, but unwieldy for mid range loads.

A Garbage Truck That Would Make Elon Musk Proud

Hartree Long distance freight: (174 comments)

The short haul is a lot easier to do with batteries.

I like the idea of catenary wires or some other way for a truck on a freeway to get electric power from the road itself.

Use battery or a hybrid system to get from the customer pick up to the nearest interstate and them hook up to the electric for the long drive, and let the truck drive itself. Have that lane separate from the manual driving lanes.

An alarm sounds when it's time for the driver to take back over (or stops the truck in a safe place if the driver fails to take back over).

Makes the control system for the automatic driving part much easier as it's just following a wire or other guide.

A Garbage Truck That Would Make Elon Musk Proud

Hartree Engines are more than just for movement: (174 comments)

Fire trucks have to use their engines for extended periods to run the on board pumps during major fires.

Bad enough having to find a hydrant. Imagine having to find an electrical outlet with sufficient current capacity to keep electric pumps going after the batteries are down.

GlaxoSmithKline Released 45 Liters of Live Polio Virus

Hartree Lotsa Questions: (209 comments)

The links aren't very informative.

Is it one of the weakened strains that's used for making oral polio vaccine? Those aren't terribly dangerous as they're already given orally to kids. They also tend to be present in the water in the areas oral vaccine is still given, as people shed the vaccine strain virus as they are building immunity.

Is it a full up wild type polio that might be used at some stage of making the injected vaccine?

And that's just a couple of questions I've got. Details makes a difference.

Physicists Observe the Majorana Fermion, Which Is Its Own Antiparticle

Hartree Re:Well that's random (99 comments)

Not so random. Maybe a long ways distant. (i.e. It's vaporware, but give us more money.)

One of the problems of current quantum computing qubits is they are easily upset by thermal and other noise from their surroundings.

There are certain systems that involve Majorana fermions that have been theorized to be what are called topologically protected states. These would be largely immune to noise in a way similar to how electron pairs in a superconductor are immune to the normal energy losses that cause resistance in a wire.

A problem with this, is, we hadn't really shown that Majorana fermions actually existed.

This is a hot area of solid state physics research. Note that these are not particles in the usual sense, but things that behave like particles (like electron pairs in a superconductor behave kinda sorta like single particles). They fall under the general term of quasiparticles.

Ask Slashdot: What Old Technology Can't You Give Up?

Cooked food.

That's a very old technology that I just can't seem to give up.

Steak tartare just doesn't sit well with my tummy, and a glass full of raw eggs for breakfast is right out, regardless of what Rocky thought.

And don't even get me started about raw potatos.

Satellite Images Show Russians Shelling Ukraine

Hartree Re:Memory Troubles: (582 comments)

In response to shelling from South Ossetia which you somehow don't think of as a violation (of an agreement that only Russia recognized). The history behind that war is long, and each side can come up with justifications.

By your logic, the current war in Gaza wouldn't be considered aggressive because Israel was responding to rocket fire.

It's all aggressive. Your logic seems to be "My guys are good, so they are beyond criticism." Horse hockey.

Google's Mapping Contest Draws Ire From Indian Government

Hartree Re:Out of the public domain? (96 comments)

"you'd be rotting in a cell for 25 years."

Mostly because the legal system is so slow it'd take that long to even get to trial.

Satellite Images Show Russians Shelling Ukraine

Hartree Re:Memory Troubles: (582 comments)

Sounds like you don't just have memory troubles, but factual troubles as well.

Russia is indeed a major player in BRICS, but the Chinese economy is fully 4 times as large. Even Brazil's GDP is greater.

Now, how a dust up in the Ukraine will sink an economic union that the rest of outweighs Russia by 6 to 1 in GDP is beyond me. The Brazillians, Chinese, and Indians are not being heavily impacted by this.

Start learning some history. This is about the fact on the ground that it's extremely difficult to defend Western Russia without having at least a neutral Ukraine. It's just not far enough from Europe to Moscow. The military in Russia has a long memory, and it includes Napoleon and Nazi Germany invading. The Russian high command knows that the defense in depth and the long cold winter retreat in both cases was what let them win. Without the Ukraine they get very nervous.

This conspiracy theory that it's all to undermine BRICS at the behest of the Rothschilds or some other bogeyman/illuminati is laughable.

"The last time the Russians got this aggressive was their invasion of Afghanistan under Jimmy Carter"

I think you're forgetting that they invaded Georgia when George W. Bush was president.

I think that counts as pretty aggressive.

This American Life Retracts Episode on Apple Factories in China

Hartree Hartree writes  |  more than 2 years ago

Hartree (191324) writes "This American Life aired an episode in January about visiting Foxconn's factory in Shenzhen China that supplies Apple with iPhones and iPads. It was the most downloaded of all of its episodes.

That show helped prompt Apple to release, for the first time, a list of its suppliers and allow outside audits of working conditions at its suppliers. (Discussed here on a previous Slashdot story.)

This American Life has now retracted the episode after finding out that Mike Daisey, whose visit to the factory the show was based on, fabricated portions of the story. This included a number of minor items, but also major ones such as his saying that he personally met underage workers and those poisoned by hexane exposure.

To set the record straight, this weekend's episode of This American Life will present how they were mislead into airing a flawed story.

TAL's press release (pdf) is here."

FBI names, arrests Anon who infiltrated its secret conference call

Hartree Hartree writes  |  more than 2 years ago

Hartree (191324) writes "Ars Technica reports: The anonymous operative that recorded a conference call by the FBI and other international cybecrime units has been arrested in Ireland.

This is due to information apparently provided to the FBI by Sabu, the LulzSec head who was named and indicted earlier today along with several other members.

Interestingly, one of the topics discussed during the intercepted call was delaying UK court cases to avoid interfering with a major operation that the NY FBI was planning.

Ironically, that operation was the investigation leading to Sabu and LulzSec's arrest earlier today. That also lead to the arrest of the person recording that very call."
