  • Is it possible to write a Shell script which is faster to the same script in perl?

    - by JohnJohnGa
    Hi, I wrote multiple scripts in perl & shell and I had compared the real execution time. In all the cases - Perl script is more than 10 times faster than shell script. So i wondered if it possible to write a Shell script which is faster to the same script in perl? and why perl faster than shell although I use the 'system' function in perl script. Thanks for your help, Regards, JohnJohnGa

  • How can I write this query in Django? (datetime)

    - by alex
    | time_before | datetime | YES | MUL | NULL | | | time_after | datetime | YES | MUL | NULL | | the_tag = Tag.objects.get(id=tag_id) Log.objects.filter(blah).extra(where=['last_updated >'+the_tag.time_before, 'last_updated' < the_tag.time_after]) Ok. Basically, I have an object that's called "the_tag". I want to select from Log where log.last_updated (which is a datetime field) is between the tag's time. But, I don't know how to write the last part of this Django query.

  • Why is it still so hard to write software?

    - by nornagon
    Writing software, I find, is composed of two parts: the Idea, and the Implementation. The Idea is about thinking: "I have this problem; how do I solve it?" and further, "how do I solve it elegantly?" The answers to these questions are obtainable by thinking about algorithms and architecture. The ideas come partially through analysis and partially through insight and intuition. The Idea is usually the easy part. You talk to your friends and co-workers and you nut it out in a meeting or over coffee. It takes an hour or two, plus revisions as you implement and find new problems. The Implementation phase of software development is so difficult that we joke about it. "Oh," we say, "the rest is a Simple Matter of Code." Because it should be simple, but it never is. We used to write our code on punch cards, and that was hard: mistakes were very difficult to spot, so we had to spend extra effort making sure every line was perfect. Then we had serial terminals: we could see all our code at once, search through it, organise it hierarchically and create things abstracted from raw machine code. First we had assemblers, one level up from machine code. Mnemonics freed us from remembering the machine code. Then we had compilers, which freed us from remembering the instructions. We had virtual machines, which let us step away from machine-specific details. And now we have advanced tools like Eclipse and Xcode that perform analysis on our code to help us write code faster and avoid common pitfalls. But writing code is still hard. Writing code is about understanding large, complex systems, and tools we have today simply don't go very far to help us with that. When I click "find all references" in Eclipse, I get a list of them at the bottom of the window. I click on one, and I'm torn away from what I was looking at, forced to context switch. Java architecture is usually several levels deep, so I have to switch and switch and switch until I find what I'm really looking for -- by which time I've forgotten where I came from. And I do that all day until I've understood a system. It's taxing mentally, and Eclipse doesn't do much that couldn't be done in 1985 with grep, except eat hundreds of megs of RAM. Writing code has barely changed since we were staring at amber on black. We have the theoretical groundwork for much more advanced tools, tools that actually work to help us comprehend and extend the complex systems we work with every day. So why is writing code still so hard?

  • Is .NET a write once, run anywhere (WORA) platform like Java claims to be?

    - by Scott Saad
    I remember Sun's slogan so vividly... "Write Once, Run Anywhere". The idea being that since programs are compiled into standard byte codes, any device with a Java Virtual Machine could run it. Over the years, Java seems to have made it onto many platforms/devices. Is this the intention or was it ever the intention of .NET. If so, what kind of efforts are being put forth to make this a reality?

  • How to not write the full url in javascript ?

    - by Axel
    Hi, I did a Mod rewrite for my website so the URLs looks like this : http://www.mydomain.com/health/54856 http://www.mydomain.com/economy/strategy/911025/ http://www.mydomain.com/tags/obama/new So, the problem is that i make AJAX calls to a file here : http://www.mydomain.com/login.php And i don't want to write the FULL url or even use ../ trick because there isn't a fixed number of folders. So, what i want now, is something worked for my code to access the login.php from the root whatever the domain name is : $.ajax({ type: "POST", url: "http://www.mydomain.com/login.php" });

  • ASP.NET Where can I write to without modifying permissions?

    - by LeeW
    Where can I write to without modifying site permissions? I need to store a value on the server that will remain when all sessions have closed and can be re-read when a new session is started. I need to make sure that no site permissions need to be changed so the location can be written to by anonymous users and any authenticated user. Does such a place exist? Thanks Lee
