    Thank you, that does explain a lot. We're a Linux shop as well, but our two graphics designers are both using the Adobe Suite on Windows.

    That is a bit reassuring. Still, one would expect that of all places, the Linux Foundation would be on a KDE desktop using LibreOffice.

    The draft of the "Let's Encrypt" Certificate Policy is available in PDF here: https://letsencrypt.org/ISRG-C... Note that the PDF document's title is "Microsoft Word". I find that rather unusual for the Linux Foundation! Wasn't LibreOffice or some other Linux-available office suite good enough to write that document? I'm surprised that they are using a Windows desktop for everyday tasks such as document editing.

  4. Re:scratch on Ask Slashdot: How To Introduce a 7-Year-Old To Programming? · · Score: 1

    The largest advantage of Scratch is the immediate results and the mixture of multimedia content that can be done with literally just a single click of a button. It can be extended to further complexity just one or two mouse clicks at a time.

    I disagree that multimedia and "click of a button" should be the goal when teaching children. Rather, I think that teaching them the computational process, and how to structure their thoughts, should be the goals.

    For this, I completely disagree that Python is a viable replacement or even worse something that should be done instead of Scratch. Don't get me wrong, Python is a fine computer programming language and perhaps as a 2nd language to teach a kid it might be very useful. It is just lousy as an introductory environment for somebody in grade school or junior high school to learn the basic concepts of computer programming.

    The other fun thing about Scratch that beats Python hands down is that Scratch is also multi-threaded with parallel processes happening as a major feature of the language. Kids doing stuff in Scratch don't even realize they are doing that kind of stuff until it is pointed out that some program/project they are making has nearly a dozen threads and even more event handlers being used. I don't see Python being nearly so easy to introduce such concepts.

    Again, I disagree. Scratch seems to be hiding so much away that one can write a multithreaded application without realizing it? How does that teach structured thought processes? If the goal is to get whiz-bang graphics out the door quickly, the Scratch sounds great. If the goal is to teach a fun, productive hobby that could turn into a profession, then it sounds terrible. I suppose that the choice depends on one's goals.

    What kind of IDE/environment are you using?

    VIM. No, seriously, my eight year old uses VIM!

    My first language was Logo. Couldn't do much with it, but it was fully interactive, which meant that you got immediate feedback as soon as you pressed Enter.

    Perhaps that is why VIM is a good choice. In the learning stages one learns to use it, and the immediate feedback is a form of gratification if it does what you intended. And when VIM does something unexpected, we laugh and wonder what we can learn from that.

  6. Re:Python on Ask Slashdot: How To Introduce a 7-Year-Old To Programming? · · Score: 1

    I wish I saw this post, I just posted above about my eight year old daughter's experience with Python. It is a great language for children, very easy to use and none of the confusing (for kids) brackets to explain. We're writing console applications such as hangman and having tons of fun. Kids don't need all the attention-grabbing flashy graphics that markets lure them with like candy. They do need something intellectually stimulating, and seeing for the first time that you can call your sister cute with this is just too much fun:

    >>> def is_cute(name):
    ...   print(name + " is cute!")
    ...
    >>> is_cute("Maayan")
    Maayan is cute!

    Sorry for the font, changing my posting settings was the only way to get the code to display properly.

    Use scratch. It's mildly obnoxious for a real programmer, but has everything you need off hand, and program flow is very easy to visualize.

    Don't.

    Python is a real programming language, and it is very easy to learn. My eight year old daughter started learning Python when she was seven, and she can write Hangman and other games. Note that we are writing _console_ games but we have a blast doing so. And her native language is not English, nor even use English letters, so if your child already knows the English alphabet and knows what "define", "print", and "if" mean, then he will already be at an advantage.

    For kids their age, it is fun just to write a function is_cute(name) that accepts the name of someone they think is cute, and then prints "AC is cute", "timothy is cute", and so on each time it is called.

    Thanks, Bert. I agree with you on all accounts.

    I've been on both ends of the assault rifle, and my children have been through one rocket damaging our home and dozens more landing nearby. The more we "advance" technology the more we enable any particular human to hurt more and more people around them. I long for the day when we forget how to forge rifles and pack blackpowder. Let the warriors (and I say this as a reserve soldier) fight with their fists. There is no way for either side to "leave the civilians out of it" when we are fighting with weapons with a ranges measured in kilometers. If you can't look the other side in the eye, don't pull the trigger / don't throw the punch / don't push the button.

    And don't be afraid to call someone a false cleric if they are using holy texts / mythology / out-of-context quotes in order to convince you to hurt somebody.

    Is it kosher then? Or does reality temporarily take precedence over mythology when someone is wounded?

    Nice veiled insult. Saving a human life is considered, as per our mythology, more important than any other commandment. We drive ambulances on the sabbath and use pig implants when that is needed to save a life. There is no "temporary" about that, it is our custom.

    Some religions value the afterlife more than human life. Some religions value vague interpretations of scripture more than human life. Some politicians value religion more than human life. Jews believe in human life first, all else second.
