• High quality graph/waveform display component in C#.

  - by dlopeztt

  Hi, I'm looking for a fast, professionally looking and customizable waveform display component in C#.

• Javascript Regular Expressions - Replace non-numeric characters

  - by user271619

  This works: var.replace(/[^0-9]+/g, ''); That simple snippet will replace anything that is not a number with nothing. But decimals are real too. So, I'm trying to figure out how to include a period. I'm sure it's really simple, but my tests aren't working.

There is any real example to use IMAGE?

• Primary zone will not transfer to secondary zone

  - by Matt Beckman

  Using DNS on Windows Server 2008, there is a constant struggle with adding primary and secondary zones. I will add a primary zone to NS1 for a new domain, edit it as needed, and when it's ready add the secondary zone to NS2. However, MOST of the time, the secondary zone remains in an error state, and will never acquire the primary zone data. I have gone back to domains a few weeks after adding them to find out that Windows never propagated the change. Annoying. Anyway, I recently updated SP1 to SP2 thinking this would help, but it hasn't. I added two new domains today, and spent an hour after the secondary zone would just not sync. During that time, the only error in the logs I had seen was for one of them where DNS complained about not being authoritative. In order to eventually resolve the issue, I ended up deleting the primary zone, creating a new primary zone, and hitting "Apply" after each and every field change. For example, after modifying the serial number from "1" to a date appropriate "2010093001", I hit apply, and then the Primary Server (apply), Responsible Person (apply), and finally Name Servers (apply). After I did this, the secondary zone didn't waste any time getting the data. Ideas?

• How to scale MySQL with multiple machines?

  - by erotsppa

  I have a web app running LAMP. We recently have an increase in load and is now looking at solutions to scale. Scaling apache is pretty easy we are just going to have multiple multiple machines hosting it and round robin the incoming traffic. However, each instance of apache will talk with MySQL and eventually MySQL will be overloaded. How to scale MySQL across multiple machines in this setup? I have already looked at this but specifically we need the updates from the DB available immediately so I don't think replication is a good strategy here? Also hopefully this can be done with minimal code change. PS. We have around a 1:1 read-write ratio.

• Is there an SCM tool made for solo programmers with key logging built in?

  - by pokstad

  Are there any Source Code Management (SCM) tools made specifically for solo programmers or small groups of programmers that tracks every small change made to source code in real time? This would require all key strokes to be tracked, and any other small changes like GUI UI editing. This seems like it would be a very useful tool for a programmer trying to remember a fix he did an hour ago that they didn't manually commit.

• Is literate programming dead?

  - by Stephen

  A fair bit is written about literate programming, but I've yet to see any project that uses it in any capacity, nor have I seen it used to teach programming. My sample may small, so I'm looking for evidence that literate programming exists and is successful in the real world.

• How to setup a webserver in common lisp?

  - by Serpico

  Several months ago, I was inspired by the magnificent book ANSI Common Lisp written by Paul Graham, and the statement that Lisp could be used as a secret weapon in your web development, published by the same author on his blog. Wow, that is amazing. That is something that I have been looking for long time. The author really developed a successful web applcation and sold it to Yahoo. With those encouraging images, I determined to spend some time (1 year or 2 year, who knows) on learning Common Lisp. Maybe someday I will development my web application and turn into a great Lisp expert. In fact, this is the second time for me to get to study Lisp. The first time was a couple of years ago when I was fascinated by the famous book SICP but found later Scheme was so unbelievably immature for real life application. After reading some chapters of ANSI Common Lisp, I was pretty sure that is a great book full of detailed exploration of Common Lisp. Then I began to set up a web server in Common Lisp. After all, this should be the best way if you want to learn something. Demonstrations are always better than definations. As suggested by the book Practical Common Lisp (by the way, this is also a great book), I chose to install AllegroServe on some Common Lisp implementation. Then, from somewhere else, I learned that Hunchentoot seems to be better than AllegroServe. (I don't remember where and whom this word is from. So don't argue with me.) Ironically, you know what, I never could installed the two packages on any Common Lisp implementation. More annoyingly, I even don't know why. The machine always spit up a lot of jargon and lead me into a chaos. I've tried searching the internet and have not found anything. Could anybody who has successfully installed these packages in Linux tell me how you did it? Have you run into any trouble? How did you figured out what is wrong and fixed it? The more detailed, the more helpful.

• Non ASCII char in PHP?

  - by domagoj412

  Hello, I am trying to send something to serial port (r232) with PHP. I am using this class: http://www.phpclasses.org/browse/package/3679.html The problem is that I am allowed to send only 1 byte. But if I send something like "1", I am actually sending 49 (ASCII for 1). Instead of send("1"), I tried with send(1) but it is no good, because this is integer which has 2 bytes. So is there a way to send a "real" char, not ASCII equivalent?

• Rails, REST Architecture and HTML 5: Cross domain requests with pre-flight requests

  - by Orion

  While working on a project to make our site HTML 5 friendly, we were eager to embrace the new method for Cross Domain requests (no more posting through hidden iframes!!!). Using the Access Control specification we begin setting up some tests to verify the behaviour of various browsers. The current Rails RESTful architecture relies on the four HTTP verbs: GET, POST, PUT, DELETE. However in the Access Control spec, it dictates that non-simple methods (PUT, DELETE) require a pre-flight request using the HTTP verb OPTIONS. In addition during testing we discovered that Firefox 3.5.8 pre-flight POST requests as well. My question is this. Is anyone aware of any project for the Rails framework working to address the issue? If not, any opinions about the best strategy to support the OPTIONS method, since it has to support the routes for all the POST, PUT, DELETE methods?

• How could a quine in my programming language look?

  - by ads

  I have created a turing-complete programming language (already proven) so it must be possible to write a quine for it, right? But all quines I know store their source code in a string and then replace a special character in it using something like chr and ord. My language only has the following Basic arithmetics Int and string types Variables == operator Conditional gotos I have no idea how I could write a quine as I have no real string manipulation available, I can only output constant strings. Yet, it is 100% turing-complete.

• automating write conflict messages

  is there any method to avoid the annoying write conflict messages by automating and hiding the process so that it doesn't appear as if the program is defective? there doesn't seem to be any point to these messages anyway as there is only one real choice which is to drop the changes.

• Implementing a continuous "revert-buffer" aka Textpad

  - by vedang

  One of my colleagues uses TextPad, and one feature I found really useful is the Auto-Reload. (The feature has been described in this SO quesion: http://stackoverflow.com/questions/1246083/alternative-to-textpads-prompt-to-reload-file). Basically, it keeps reloading the file without any prompt from the user, which is really helpful when monitoring log files that are updated in real-time. Is there something similar available for Emacs? If not, can anyone whip up the required elisp magic?

  I am currently using Microsoft's MODI (Microsoft Office Document Imaging) to read text in an image in C#. Everything is working fine, except some of the words I want to read are not real English words. Is there any way to use a custom dictionary when using MODI or add words to the regular English dictionary that it uses?

• Get cookie expiration

  - by Ashish Rajan

  Is it possible to read cookie expiration time with php ? When I print_r($_COOKIE) it outputs: Array ( [PHPSESSID] => 0afef6bac83a7db8abd9f87b76838d7f [userId] => 1232 [userEmail] => [email protected] [firstName] => user [lastName] => user ) So I think $_COOKIE don't have the expiration time, is it possible with some other function?
