Comment Re:Copy machine at stores (Score 1) 62

The main use I can see for such a machine is printing replacement parts for the cheap bit of plastic that breaks in a load of consumer equipment, but where the replacements are too difficult or expensive to buy. Unfortunately, doing that well will also need some kind of 3D scanner so that you can put in the broken bit and modify it (e.g. put in two parts and then drag them around until you have a single object).

Comment Re:treating the symptoms (Score 1) 230

You do realize that the federal government does allocate funding for schools in the exact same manner as highways and food stamps or housing and so on right? Outside of social security and medicare, it is all passed to the states for the state equivalent program to administer with strings attached to how it can be spent. The bulk of all of that is funded by state and local entities in the same way schools are funded. Highways are funded through a fuel tax and certain excise taxes on tires and such but the federal government has a constitutional right to establish post roads (highways)

And I didn't realize the context of your comment at first. I should have replied to the grandparent instead of you. But the manner in which taxes are collected is not an excuse, it is the order of things. The feds only have as much power as was ceded by the states via the constitution and their ability to stretch clauses beyond obvious meanings. War is a constitutional role for the federal government, schools- not so much. The same with everything else you listed. It exists as some stretch of some related power granted to congress which is why the funding is passed to the states to administrate.

Kind of the first joke I thought of too; but... what if our desire to ask such questions is the result of some sort of built-in bias? What if truth is N-dimensional and we just can't conceive of it in any real way? Note, not gradations of T and F, but an actual N-dimensionality of veracity. Like, I'm telling the truth, I'm telling a lie, or I'm telling an arrow.

what did they replace SystemD with and how does it log?

Unless they tell you so, you should assume they did something sensible like use something syslogd compatible, and if you don't like it, you can switch to another one. From googling I get the idea it's rsyslog.

Comment Re:Init alternatives (Score 1) 123

The truth is that the boot speed improvements of systemd are effectively notional. The boot process is so fast now that starting in parallel only saves you time when something goes wrong. If you regularly have a problem during boot, then you should think about fixing that regardless of what your init system is.

The US government has never funded schools by much to begin with. It simple isn't their job to and all the funding they do give comes with strings saying how and when the funding can be spent.

The states and local municipalities largely fund schools and those political entities do not fund the wars. Your decrease funding to pay for a war might sound good but it shows a lack of knowledge on the scope and magnitude of education funding in the US.

You are correct to a degree. But this wouldn't be an ex post facto law. It would be the same as a no smoking in a public building law. It just means that actions that was once legal (smoking at the courthouse) is now not legal. So existing contracts would just become unenforceable in respect to the law after the law takes effect but nothing makes the provisions before the law takes effect illegal or punishable. This is further complicated with Calder v. Bull which sort of takes the line that only criminal laws can be ex post facto. So unless this law provides criminal punishment, the courts would likely ignore any ex post facto claims.

Now if the law says anyone who had one of these contracts before the law takes effect will be fined or imprisoned or otherwise punished, the ex post facto clause certainly would become valid. But a new law just means you have to change your behavior from the date it takes effect.

Interestingly, we have seen this ex post facto law situation with interest rates in which congress changed the rates for the Stafford student loan program to rates lower than contracted rates for a period of time from July 1 to to august 9th of 2013. H.R.1911 actually has language in it saying that it takes effect as if it was passed on July 1st 2013 even though it was signed into law a over a month later. Yet nobody challenged it.

Comment Re:I thought diesel ran cleaner (Score 1) 215

Expanding isn't "reacting to heat".

What? What do you call it, then? I didn't say it was reacting with heat. Although it does react with oxygen in the presence of heat, to form NOx, that's explicitly not what I was talking about.

But, back to the original point: Diesel engines take in much more atmospheric air than gasoline engines when running at normal loads (highway cruising).

Yes. But they consume no more when wide open. The size of the exhaust is defined primarily by the maximum flow, not the cruising flow. (That defines other design characteristics more.) Diesels tend to have higher peak boost in spite of their typically higher static compression ratios, but they also tend to have significantly lower RPM limits and tend to run less RPMs while cruising.

Of course, all of this has been muddied by the introduction of the direct-injected gasoline engine, and by developments in diesel engine technology. Not only do GDI motors have higher cylinder pressures and thus higher temperatures, but there are also now diesels with [automated] throttles. As well, the recent crop of automatic transmissions with many gear ratios (8 now being common, 9 not being uncommon, and 10 beginning to roll out) and multiple overdrive ratios has led to gasoline engines being used at much lower RPMs...

Comment Re:How the fuck.... (Score 1) 215

Yeah maybe in America. But that is a fantasy land in terms of fuel. This article however is talking about other places in the world.
In Australia for example most heavy busses have switched to running nat gas because it was cheaper. Most taxis and many passenger cars did too though these are being displaced by electric.

all of which makes sense, but what about long-haul trucking? the hauls are really long in oz.

Comment Re:Think outside the container... (Score 1) 215

I can't help but be a little amused at all the people saying cities could never ban Diesel because there's no acceptable alternative.
There is, of course, just not for long-haul trucking.

You could probably switch to turbine-electric and burn... well, whatever you wanted really, but the only thing which would have the same kind of energy density is jet fuel. That would only cost what, an order of magnitude more or something? But the good news, everyone, is that we're all going to be getting higher-grade fuels whether we like it or not. It's not going to be possible to get much better emissions out of internal combustion vehicles without them. The automakers want to see even higher-grade diesel fuel, and higher-octane gasoline.

Of course, if the Trump takes a Dump on CAFE somehow then we might well not get any of this stuff any time soon...

It doesn't matter what score or moderation the parent is. I as everyone should, surf slashdot at -1 and give bonuses to troll and other down mods specifically because people with agendas will use the moderation system to hide dissent.

So to a regular logged in user, your point is largely lost unless that user is only looking for an echo chamber to agree with themselves. Otherwise, they would have modified their levels also and view low scoring post.
