Universal Big Bang Lithium Deficit Confirmed

spitzak Re:Quite accurately? (170 comments)

You may have seen tables of various isotopes of Hydrogen and Helium, those seem to match predictions very well, and there are more than 2 of them, which may be why you are thinking it may go above 2 in the atomic table.

Universal Big Bang Lithium Deficit Confirmed

spitzak Re:Quite accurately? (170 comments)

The model can give a "quite accurate" expected value, even when wrong. Example (note numbers are completely made up):

Say there is model A which predicts 2.5-2.6% lithium.

Say there is another model B which predicts 2%-8% lithium.

Say in reality there is 1% lithium.

Both models are apprently wrong. But Model A is more "accurate" in making the wrong prediction. Therefore the text in the article is perfectly correct.

Get it?

Information Theory Places New Limits On Origin of Life

spitzak Re:Empirical Data Trumps Information Theory (211 comments)

Actually it will be a lot worse than Venus and due to a different cause in that the sun would actually be irradating many times more energy on it, and possibly even engulfing it in hot plasma. Venus is heated by the insulation of a huge amount of CO2, the Earth with that much CO2 would be equally hot, and Venus without it would be just a tropical Earth. And when the sun expands the CO2 will be irrelevant (I would think the heat would actually make it escape to space), not that that is going to help any.

To Really Cut Emissions, We Need Electric Buses, Not Just Electric Cars

spitzak Re:Container ships (486 comments)

I don't know if this is a troll, but if not you may be a bit confused about who is "falling for this". It seems you are as you just listed a few outright lies and distortions.

To Really Cut Emissions, We Need Electric Buses, Not Just Electric Cars

spitzak Re:Container ships (486 comments)

If you believe the environmental cost of making a new car exceeds the savings of using it instead of an old car, then you are the one that is duped. This has been debunked many times. Guess the person who thinks they are 'smart' is you.

Ask Slashdot: What Are the Strangest Features of Various Programming Languages?

spitzak Re:question colon (729 comments)

In Python you write "a?b:c" as "b if a else c". I think that is pretty obscure, and hard to read too.

Ask Slashdot: What Are the Strangest Features of Various Programming Languages?

spitzak Re:Powershell (729 comments)

Null-terminated strings were considered superior to using a length because they allowed strings to be > 255 bytes long (using 16 bits for the length would allow longer counted strings, but at that time with 4K of memory nobody in their right mind would suggest wasting a byte like that!).

Null-terminated strings also have the nice property that getting the "tail" is a very fast operation, since you just return a pointer to the middle. This meant that searches could return strings, rather than indexes. This then meant that every function that worked on text only needed one argument, a string, rather than two (a string and an index). The savings due to this were pretty significant.

The Grumpy Programmer has Advice for Young Computer Workers (Video)

spitzak Re:Programming: You're doing it completely wrong (120 comments)

I was talking about the pre-lambda stuff in std and boost, especially std::foreach.

C++11x did in fact fix a lot of this and I certainly use the new syntax.

The Grumpy Programmer has Advice for Young Computer Workers (Video)

spitzak Re:Programming: You're doing it completely wrong (120 comments)

Actually more often I have seen the opposite: claims the new stuff is going to be faster, the compiler is not smart enough to figure out that they are the same, and thus you should use the new stuff.

There was a coworker who insisted that using C++ std::foreach for loops was faster because "the compiler knows you can't break out of it and thus can optimize the whole thing". I had two objections to this: first of all it would be a really stupid optimizing compiler that could not figure out there are no "break" statements inside the for loop. And second the C++ was still allowed to throw exceptions in both cases.

The other objection I had was that the functors were unreadable.

Yet another objection is my suspicion that the optimization would be far worse on the functors due to the enormous header files of templates they actually used and I expected the optimizer for the simple for loop to have fewer bugs in it. But I did not test this.

Larry Rosen: A Case Study In Understanding (and Enforcing) the GPL

spitzak Re:Compelled to freely license? (191 comments)

Copyright violation conviction results in having to pay monetary damages to the copyright holder, and to cease redistribution of the copyrighted work.

Fulfilling the requirements of the LGPL on new copies in no way is required by, and conversely also does not get you out of, the punishment. Therefore for every possible reason in the book this "viral" idea is false.

Larry Rosen: A Case Study In Understanding (and Enforcing) the GPL

spitzak Re:more gpl non-sense (191 comments)

You are stating a LIE that was written by MicroSoft. Absolutely not what Richard Stallman said.

The GPL does not compel anybody to freely license their product. What it does is make you violate copyright if you include GPL code in that product. The punishment for violating copyright is defined by law as monetary damages and a requirement to STOP distributing (and stopping is the exact opposite of being forced to distribute, you know).

Thanks for proving your ignorance.

Larry Rosen: A Case Study In Understanding (and Enforcing) the GPL

spitzak Re:Do What Though Wilt (191 comments)

I assume you just completely missed the fact that the original company was making money by selling a commercial license for their code? They certainly did not want to use the BSD license.

Larry Rosen: A Case Study In Understanding (and Enforcing) the GPL

spitzak Re:The viral argument is misleading. (191 comments)

None of those get you off the hook for the previous copyright violation.

Also starting to distribute your own source code does not fix it either.

The viral argument is worse than misleading, it is totally wrong. The concept does not exist, it is a LIE being perpetuated by various parties for who defeat of open source is in their interests.

Larry Rosen: A Case Study In Understanding (and Enforcing) the GPL

spitzak Re:Compelled to freely license? (191 comments)

No, it has NOTHING to do with "infection". That is a FALSE concept, a LIE perpetuated by MicroSoft to discredit the GPL. There IS NO SUCH THING AS "infection".

What the LGPL does is give you some more methods of distributing the code without violating copyright. It has nothing to do with the punishment if you violate copyright, which does not change in one bit! And that punishment does NOT include 'you are forced to distribute stuff you have copyright on for free'. It just does not contain that in any law in any jurisdiction. So stop it with the lies.

Larry Rosen: A Case Study In Understanding (and Enforcing) the GPL

spitzak Re:Compelled to freely license? (191 comments)

No you are wrong.

The license gives rules that you must follow if you don't want to violate the copyright. There are other ways of not violating the copyright, an easy one is to not distribute a copy at all!

The license is enforceable. If you don't follow it you have VIOLATED COPYRIGHT, which is against the law.

But you are making the bogus and false statement that the punishment for violating copyright is to force you to continue distributing it but obey the license. That is FALSE. The punishment for violating copyright is that you must cease violating it (ie stop distributing!!!!!) and pay monetary damages to the copyright holder.

Conversely starting to obey the GPL on new distributions does not get you out of anything. You have still violated copyright with your earlier copies and therefore not only are you not forced to distribute code, it does not even help you!

You are repeating one of the biggest lies being perpetuated by MicroSoft. Don't be such a tool.

'Just Let Me Code!'

spitzak git and code review (372 comments)

I seem to be spending a lot more time rebasing git commits and reading/writing code reviews and doing the necessary email to merge request further-rebased git commits into the main branch than actually fixing the code.
