    I personally wish that this worked so we could use it for fusion fuel. Sadly, you need protons from somewhere to get even a _vaguely_ stable Helium atom, which is why all the even testable fusion reactors use deuterium and tritium.

  3. Cannot scale anyway on How Close Are We, Really, To Nuclear Fusion? · · Score: 2, Interesting

    I've explained this on Slashdot before: Even if such plants reach "break even", creating more available energy than they use to run, they can't possibly scale to production use because the tests that are even _slightly_ successful use tritium as a critical fuel component. And the only viable source of tritium is ordinary nuclear fission reactors: there is no scalable natural source for it.

    There is _no_ fusion technology ever tested, nor realistically proposed that does not rely on tritium. And every source of tritium itself, either earth-bound fission or potentially solar sail collectors for solar tritium, is _itself_ far more efficiently used as a straight power supply by itself. Sustainable fusion is interesting as a technological accomplishment, but it's not a viable power source unless the need for tritum is eliminated.

  4. It's too late on Ask Slashdot: Advice On Enterprise Architect Position · · Score: 1

    What you describe is a political issue, not a technological one. Unless you've already made strong friends with the IT staff, and _earned_ their respect and trust, expect them to resist you at every step. In particular, expect their middle management layers to disagree with every move and sabotage them behind your back. And I'm afraid you're starting out with a basic confusion: "3000 employees" is not a medium sized, company, it's a _big_ company. I'm also afraid that if you think of it as a medium size company, you'll be tempted to micromanage individual employees and pet projects. You're not going to have time for this, really.

    Earning the respect and trust of the existing staff is going to be awkward. You're going to need that: they're going to need questions answered, clear decisions made with clear justification, and a clear set of technology and social practices so they know what is expected. Documentation, backup, and standard practices for network and environment configuration are all going to come from or be signed off on by you. If they disagree with a practice, they need to be safe to express it safely, work with you to iron out the differences, and if it turns out one of you were dead wrong, to get the other's insight credited and the other person educated on why the right practice is just that.

    And I'm afraid many practices aren't that clear-cut: flexibility versus recoverability, reliability versus expense, growth over repair are all going to require decisions coming from you, as an architect. And even when you make the "right" decision, sometimes things are going to break that the "wrong" decision would have avoided. Some of them are going to be _large_.

    That's partly why the existing staff are afraid of handing over admin access. Another possibility is that they're _embarrassed_ and you'll have immediate visibility into what they're embarrassed about. I've had tremendous difficulty with staff leaving in unannounced backdoors "to get their jobs done" and not wanting me to know about them. I've even been booted right off a project because I kept going to the manager with "your technical leader is putting in backdoors for his telecommuting here, here, and here, in direct violation of SOX guidelines: I can't sign off on this".

    Anecdotes aside, you're going to have to establish trust with these people. From your short description, it sounds like they've been thinking of you as the enemy. If they're unhappy and can't work with your vision, check if your vision is confused and you can accommodate their ideals and goals. If you can't incorporate their goals, or if they're just plain wrong, show them the door gracefully. And let them know what your "vision" is, so they can be sure if you'll like their plans or if they're going to have trouble convincing you something is workable.

    The best way to show them the door is to help them get hired somewhere else better suited to their neds as well as yours. I've had good success with staff who'd outgrown our environments, or our environments had moved to new practices they didn't care for, helping them find work with partners and other companies who appreciated their approach. I've even done a few flat-out exchanges: "You need a new security expert, we need a new backup expert", we've swapped staff, and we both came out better for it.

    Or both., I'm afraid. Or the survey was badly constructed. I've seen a number of security compliance surveys, especially now with HIPAA laws affecting health care security, that were designed to allow hospital IT departments to claim more or less security with subtle interpretation. The result is that for medical IT staff who needed more security funding, and wanted to justify the work, they'd answer the surveys one way and say "we have a problem, we need to spend money". And if they wanted to report success the next year, despite no genuine oerall change, they'd choose other similarly "interpritive" answers and point to the improvement in security.

    The stroke he suffered while writing "Number of the Beast" affected Robert Heinlein a great deal. I'm afraid having so many adoring fans, and editors who grew up with his earlier work, gave him enough influence that editors didn't dare to rein in his works with the plot unification and cutting of excess themes that a good editor would apply to a less successful author. It's a common problem for successful authors, and coupled with his age and the stroke, I'm afraid Heinlein's work suffered.

    The "Heinlein juveniles" were exciting and inspirational work for many people, especially engineers. His characters were humans, many were engineers by nature if not by trade, and they bothered to do the work to master their crafts and to use the available tools to their full extent. The Lazarus Long anecdotes were filled with the lessons of an old man who's learned tremendous wisdom and tries to share it, and the Moon is a Harsh Mistress explored family life and guerrilla warfare and space-based warfare and the moral ramifications of AI and shortsighted politcal thinking, all in the same story. Stranger in a Strange Land explored the idea that language shapes thinking, and that to fully understand something is to love and cherish it as it exists, but does _not_ mean accepting that it should continue to exist.

    I recommend Heinlein's older work to youngsters today in much the same way I recommend Terry Pratchett's fantasy work. They're entertaining, they pay attention to the consequences of technology and technological shifts, and they carry interesting moral lessons.

I've seen this a great deal, with pointless code churn and endless "meetings" used to justify the size of a group that is accomplishing very little, for group members to take on irrelevant projects, and to leave only a few core people doing any real work.

    > That is a non sense sentence. What exactly is an unreliable compilation?

    "Unreliable compilaton" could mean many things. Code that is likely to give different results based on subtle compilaton option differences, such as optimization levels, due to assuming default population of uninitialized variables is my current favorite. Code that produces different binary functions dependent on compiler assumed architecture is another, such as using "int" versus "uint_32", is another older favorite from when I did more porting of 32-bit code to 64-bit environments. Code that relies on replacing system libraries with its own particular "tuned" versions of libraries or standard OS functions is another, since it becomes vulnerable to inconsistencies in the compiler flags and a developer who fails to set them correctly can get surprisingly inconsistent behavior.

    Other features do not so much prevent compiler inconsistency, but help with programmer consistency. Following the local style guide, using consistent naming schemes for variables, keeping memory handling in one consistent area of code so "free" and "malloc" are easily tracked, and sanitizing I/O before relying on it are all aids to consistent behavior.

    Given the accusations and abuse heaped on various software project leaders or contributors, it's more common than you may realize.

    Also, I'm afraid that the standards for what constitutes "molesting children" vary from culture to culture, and even from state to state. There are cultures where clitorectomy, which I would certainly classify as sexual abuse of children, is considered part of proper upbringing. Looking at https://www.cga.ct.gov/2003/ol... for rape statutes, the first state listed considers it a felony for an 18 year old to have sex with a 15 year old.

    Even marriage among siblings has occurred in small communities, and among royalty, throughout history. And sexual play among siblings is surprisingly common among humans and other mammals. This doesn't mean that I, for one, recommend it. But by itself, without violence or threats or other harassment, it should not turn the recipient of sexual molestation into an automatic object of lifelong pity.
