  1. Re:Obvious Solution on Equipment Failure May Cut Kepler Mission Short · · Score: 1

    If I remember right, there already is a successor in the pipeline. Anyway, I would be surprised that the end of Kepler would be the end of the exoplanet revolution. It's a very hot field in astronomy. There's a scientific gold vein out there, people will keep digging. Kepler is a significant milestone, and one of my favorite missions, but not a unique instrument. It's the beginning, not the end.

    The shuttle was nowhere near capable of flying to Kepler. It's at 40 million miles, while the space shuttle could only fly up a couple hundred miles. Besides, considering the cost of the mission, it would not warrant a complicated repair mission. For that money you could probably send up 10 new telescopes.

    Only persons who WANT to believe in God will attribute the origin of life to him.

    What I believe or don't believe has nothing to do with what I want. It would be rather stupid to believe something is true because you want it to be true.

    Adding vast amounts of time does not solve the problem because no one was there to observe life come into existence.

    Suppose someone was there to observe it, what problem would then have been solved? We would have a historical claim about the abiogenesis, but that would be it. That's not science, it explains nothing. We could even doubt the veracity of the claim, and there would be no way to settle it.

    Adding large amounts of time does not answer any question, indeed. The only thing it does (together with the vast scale of the universe), is that very rare events can not be ruled out. Again, nobody knows how life started and it is quite possible we will never find out, but I have no problem with not knowing. I don't feel a need to invent invisible magical creatures that then magically created life. That would be silly.

    Even the simplest single celled organism is unbelievably complex and contains a prodigious amount of information. The theory that life on Earth was seeded from space begs the question, how did that life begins wherever it did begin?

    That's true. But somehow you don't seem to draw the correct conclusions from that. When confronted with something complex, the theory of evolution tells you it can not have formed instantly, but instead it happened gradually. Therefore, the "starting point" of life is at the molecular level, not at the cell level. And I put the quotes there deliberately, because there won't be a single point, it will be a gradual process. Just like there isn't a point where there is a "first tree" or "first human".

    Even with the best efforts of intelligent scientists and the expenditure of mountains of money, no one has yet created any life form whatsoever from nonliving matter.

    So what? Why should we be able to create life? Why should it be simple? There are an unknown number of possibilities to consider. It might have been a freak accident or rather trivial, nobody knows. Whatever the odds, in a universe this big it is rather a non-issue.

    I'm old enough to remember when cellphones first appeared. First when someone pulled a phone out of his pocket, everybody looked, made a joke, laughed, whatever. A few years later, almost everybody had one. Another few years, and the first reports of people whose phone had fused with their hand started to pour in. I doubt that 'not socially acceptable' will be a major issue.

    So basically that's a sort of pulse-width modulation. The same technique used in DC-DC converters to maximize efficiency. Keep the motor running at maximum efficiency. Fine. Now take a look at this again: "alternately slow down and speed up to take advantage of regenerative braking". Can you spot the difference?

  12. Re:You clearly didn't review the charts given. on NY Times' Broder Responds To Tesla's Elon Musk · · Score: 2

    Look, the most efficient way to move is at constant speed. There is no way on earth that speeding up/slowing down is going to be more efficient. You need energy to speed up, at less than 100% efficiency, and you recuperate energy from slowing down, at less than 100% efficiency. How can that ever prolong battery life? That's basic highschool stuff. If the reporter has a highschool degree, yet is unaware of that, then that's quite embarrasing for the educational system.

    It's true that accusing the reporter to lie is a serious one, but so is accusing the technical support staff of such incompetence. That leaves that there was a misunderstanding between the two: maybe support wanted to explain how to optimally slow down to maximize energy recuperation, and the dumb reporter didn't understand. Or maybe Tesla hired a moron for tech support. All are possible. With all results being possible, that is equivalent to saying that no conclusion can be made. So: do the test again, better this time.

    There are some fishy things though. When he's presented with logs, all of a sudden everything he did is because of tech support. Very convenient. And then there's tech advice like this: I was given battery-conservation advice at that time (turn off the cruise control; alternately slow down and speed up to take advantage of regenerative braking).

    Why would such a thing work unless you believe in perpetuum mobiles? I mean, seriously, the world needs more BS detectors. It's possible some nitwit gave hime that advice, or the reporter misunderstood, or he lied.

    Unless the phone logs are kept, we'll probably never know. The only thing remaining is to repeat the test, or continue argueing untill the sun turns into a red giant.

  19. Been there, .. on Ask Slashdot: How To Convince a Team To Write Good Code? · · Score: 1

    I used to work on a project that shows some similarities. Ad-hoc coding, feature creep, heavy time constraints, overly complex code, ... Don't expect miracles. If you start with a heap of dung, it is never going to smell good.

    I sent an e-mail to my manager detailing 4 of the most critical problems. Fortunately, he was wiling to hear them, and we made some changes that improved the situation. But when I left there was still a scheduler (to start and stop machines at specific times) that was never rewritten. It was funny, the day I left I found the e-mail again, and then I heard a fellow-engineer had been assigned to make a trivial change to it. Expected amount of work: two weeks.

    If the problems lie deep, it is wishful thinking that you can simply fix it. In a perfect world, you would start over again. In reality, there are all sorts of constraints. Here are some tips:

    Analyze the project history: try to discover what files are changed the most, what kind of changes are mostly requested, are there modules that produce a spray of bugs whenever they are touched etc. (you do have a bug tracking system, right? If not, get one now!).

    With that analysis, try to isolate some pieces of problematic code. Remove all sharp objects from your desk while doing this, because you might want to poke your eyes out. Focus on a part that changes a lot and see how you may fix that. To give an example: every time new menu options had to be added, the guy who wrote that became pale and mumbled something and went off to implement it. A few days later it became available, with some bugs like wrong menu's popping up. So when I tried to find out what was the problem, it turned out that every goddamn menu-item had a hand-coded position ID. so if a new item had to be inserted, all the next menu's needed their id's to be incremented, and all references to those id's updated. Using some rather advanced macro's (including concatenations), I managed to clean that up. It's not cleanest solution, but it only took me 2-3 days to implement, and after that, new menu's could be added in no time and without bugs. Also, anyone could add them.

    What I want to say with this: you may improve the situation without making extremely drastic solutions. If you make just a couple of such changes, these can already have a drastic impact on development time. More importantly, it will not go unnoticed, and change the dynamic of the team and management. People will start asking the right questions: how can we further improve the situation? At that moment, your voices will be heard much louder.

    If there are no test cases (as was the case for me too), you have to reconcile with the fact that it's too late. Try to add test cases for new modules, but realize that retro-fitting unit tests to a large project with low-quality code is not realistic. The next best thing might be adding assertions wherever you encounter bugs. Also adding sanity checks (e.g. testing if large object trees contain valid data) may prove helpful in debugging.

    I hope that helps, and best of luck.
    Any further criticism/advice is always welcome.
