How to have website think you're visiting from a different country? Please be careful with localizing. Years ago I ran into a nasty one--a webmail system that insisted on using my localization and there was no way to override it. It wasn't my system, though, and I don't speak the language it was set for. |

Looking for meaningful, strong argument in favor of antivirus software on development machines @grasGendarme I don't find it stupid, it's just the AV is protecting stupid users. The average user isn't going to be legitimately receiving e-mail with executable attachments and thus any such attachment is likely malicious. If you jump through the hoops of changing the extension to get it to run you've shown you perfectly well know it's executable content and you probably know what you're doing. |

Does Turing-complete implies possibility of malware? Would not a system that was totally sandboxed be immune to malware even if it was turing complete? (How useful it would be with no ability to persist state would be another matter...) |

Why are there so many numeric types (bit, int, float, double, long)? 3) albeit rarely an issue: Operations on numbers bigger than the computer's wordsize are slower. |

Is it just me or is this a baffling tech interview question? A variation on #3--they're trying to hire H1-Bs and thus need to show any Americans that apply are unqualified. |

Is Software Testing Really Needed? @AndresF. The killer problem with the Therac-25 was the result of a command to the hardware getting lost if it was still executing the previous command. It was a bad software design but simply applying testing procedures to it wouldn't have shown up the problem. The code didn't know it was firing the high power beam without the deflector in place. |

Optimization algorithm, how to develop this problem I think his use of time for Y means that it's how long the space is occupied by the item. |

Notation for the average time complexity of an algorithm The thing is you retain only the highest order term, nothing else. Thus O((n+1)/2) is O(n). |

I don't know C. And why should I learn it? @Stephen Knowing how the computer actually works can become very useful when you're trying to debug the weird cases. I am of the opinion that all competent programmers need to be able to read the assembly language of their system so they're not lost when they suddenly end up with a screen full of it. (Note that writing it is another matter, that's a specialized skill most programmers will never need.) |

A colourblind member of our team And what if you run out of colors he can reliably tell apart before you run out of colors you need? |

A colourblind member of our team @juan2raid: Worse than colorblindness is those with impaired color vision. Many men (it's carried on the X and thus far more common in men than women) don't even know they have it. My former employer tested all factory floor employees so supervisors would know who couldn't do the two color-sensitive jobs in the factory. 20% failed, most of them had no idea their color vision was flawed. |

answered | In functional programming, are local mutable variables with no side effects still considered “bad practice”? |

Is Bubble Sort the slowest sorting algorithm? In the old days before we had sort routines in our libraries bubble sort had the advantage of being very easy to implement. There are times it's actually a reasonable solution--when n has a very low hard limit. |

Theory about software communications mixing up with other software causing an Apocalypse? In the real world the packet is going to need authentication codes and it's going to be encrypted. The authenticator alone is going to be long enough to preclude guessing and in addition we need a minimum of the weapons system, yield, target and time (although the latter will normally be ASAP.) If they can get all that in 30 characters I would be very surprised. Since it's encrypted you need to hit that with 30 random bytes. 8 bits/byte, there are 2^240 possible 30 character strings. By chance? Hah! |
