Comment In Academic Projects (Score 2) 435

We use C++ exclusively for academic projects but we rarely use STL for performance reason. Some of the C++11 functions really come to rescue like number to string conversion, time keeping etc that may save a day but in general we use "templates" almost everywhere but use of STL is limited to some once in a while operations like loading data from an input file.

Comment Overgenralized scenario. (Score 2) 278

When people work in a group as a team this inevitably happens and that's all right. Building a perfect software that satisfies everyone is a hard NP problem. What's the point of being perfectionist if that 10% you wish to polish it going to consume 90% of your time and money.

Comment The Final Explanation (Score 2) 360

Two phenomena are at work:
1. Atmospheric pressure is needed to take the fluid till the apex. It will not affect the rate of siphoning but it is a necessary barrier that has to be overcome.

2. Once atmoshperic pressure has done its work, the rate of flow of fluid will be completely determined only by the difference between the heights of two ends of the pipe and the amount of gravitational force.

Comment Equations: (Score 1) 360

The total pressure acting on water in the pipe is

[P(air) + P(h1)] - [P(air) + P(h2)]

where h1 is the position of upper end and h2 is the position of lower end of the pipe.
If you want to siphon the liquid fast, either lift the upper end or lower down the lower end of pipe, which is the proof that gravity is in action.

Although, P(air) gets canceled in a regular siphon as in the equation above, if air pressure is different at two ends it will start affecting the flow. Obviously, in outer space P(air) will be zero and P(h1) and P(h2) will be very weak.

Comment Human-aided computer sort (Score 1) 195

The method I commonly use is human-aided computer sort. This is how it works. You hand over the sixty or something papers to 60 people while entering the sortable field of each paper in a spreadsheet as you do it. Sort the field on the spreadsheet and collect the sheets back from the fellas in the sorted order. As a bonus you get the soft copy of the entire index. And it only takes O(n).

Fast vs precise vs versatile

You can hum a tune and record it on your phone.
Why do we need musical notation then?
The answer is ... precision.

I like the Python/Ruby approach: do more with less code. That's the best it can get.

And if you really really want to code using fancy blocks and rectangles (like those in flowcharts), imagine the nightmare those malformed graphics elements arranged in ever increasing network like layout with exponentially increasing connections will cause when much easier things like syntax highlighting sometimes sucks.

Code visualization and visual coding may be used as a secondary aid.

Comment No regrets (Score 1) 2219

Slashdot beta used to suck 6 months or a year ago (whenever its existence was first revealed), it sucks enough even today. If anything good about it had to happen it would have happened by now. So based on my own experience, I am fairly convinced that there is no point expecting anything good from the beta site.

I've already blocked the beta site using a browser plug-in. I've never failed to respect my own experience and my honest beliefs and these are the common elements that bind me to the other readers, their stories and their comments. And for the sake of them, if I have to leave slashdot (in case classic is discontinued), I'll leave and never look back. No regrets.

Make your move mods.
