• High CPU - What to do.

  - by Udi Kantzuker

  I have a high CPU problem with MYSQL using "top" ( linux ) shows cpu peaks of 90%. I was trying to find the source of the problem, turned on general log and slow query log, The slow query log did not find anything. The Db contains a few small tables and one large table that contains almost 100k rows, Database Engine is MyIsam. strange thing i have noticed that on the large table, select, insert are very fast but update takes 0.2 - 0.5 secs. already used optimize and repair and no improvement. the table is being updated frequently, could this be the source of the high CPU% ? What can i do to improve this?

• Java sockets: can I write a TCP server with one thread?

  - by hmp

  From what I read about Java NIO and non-blocking [Server]SocketChannels, it should be possible to write a TCP server that sustains several connections using only one thread - I'd make a Selector that waits for all relevant channels in the server's loop. Is that right, or am I missing some important detail? What problems can I encounter? (Background: The TCP communication would be for a small multiplayer game, so max. 10-20 simultaneous connections. Messages will be sent about every few seconds.)

• How to split and join array in C++?

  - by Richard Knop

  I have a byte array like this: lzo_bytep out; // my byte array size_t uncompressedImageSize = 921600; out = (lzo_bytep) malloc((uncompressedImageSize + uncompressedImageSize / 16 + 64 + 3)); wrkmem = (lzo_voidp) malloc(LZO1X_1_MEM_COMPRESS); // Now the byte array has 802270 bytes r = lzo1x_1_compress(imageData, uncompressedImageSize, out, &out_len, wrkmem); How can I split it into smaller parts under 65,535 bytes (the byte array is one large packet which I want to sent over UDP which has upper limit 65,535 bytes) and then join those small chunks back into a continuous array?

• Why does this program segfault

  - by Leda

  Upon compiling and running this small program to reverse a string, I get a Segmentation Fault before any output occurs. Forgive me if this is an obvious question, I'm still very new to C. #include <stdio.h> int reverse(char string[], int length); int main() { char string[] = "reversed"; printf("String at start of main = %s", string); reverse(string, sizeof(string)); printf("%s\n", string); return 0; } // Reverse string int reverse(char string[], int length) { int i; char reversed[] = {}; int temp; for(i = 0; i < length; ++i) { temp = string[i]; reversed[length - i] = temp; } return 0; }

• What do browsesr use to auto suggest values in web forms?

  - by nedlud

  If I come back to a web site after having filled in a form previously, the browser remembers my username (for example). I'm not talking about cookies remembering user names and passwords, but the way a browser will suggest a value for a previously submitted field. What controls this behaviour? My issue at the moment is that I have login forms on several small apps all running under the one domain. (eg www.example.com/app1/login/ and www.example.com/app2/login/). If I use my user name for app1, then go over to app2 where I use a different username, it only ever auto suggests my app1 user name. How can I change this behaviour? Do browsers use the fields ID to help remember this stuff? If I change the ID of the fields in the login form, will they auto suggest the correct values in future?

• How do I get the sequence of numbers in a sorted-set that are between two integers in clojure?

  - by Greg Rogers

  Say I have a sorted-set of integers, xs, and I want to retrieve all the integers in xs that are [x, y), ie. between x and y. I can do: (select #(and (>= % x) (< % y)) xs) But this is inefficient - O(n) when it could be O(log n), I expect the number of elements returned to be small. Using take-while and drop-while would let me exit once I've reached y, but I still can't jump to x efficiently. I am just learning clojure so here is how I would do it in C++: set<int>::iterator first = xs.lower_bound(x); set<int>::iterator last = xs.lower_bound(y); for (; first != last; ++first) // do something with *first Can I do this in clojure?

• iPhone Accelerometer Values

  - by Mike

  My question is about the iPhone accelerometer. Does the accelerometer measure acceleration or movement of the iPhone? What I mean is if I hold the iPhone and go from 0mph to 60mph, I would expect the measure of acceleration to increase in value from 0 to 60, but once I reach 60, I expect the value to return to 0 since I am "no longer accelerating" but am moving at a constant speed. Now if the accelerometer measure motion, I would expect it to register 0 to 60 and continue to provide a change in value as I move forward at 60mph. Sorry, I looked at a few books, programmed some code (values seemed to small to give a recognizable result over short distances or speeds), and a lot of web searches, and I am trying to get an answer to this question. Thanx!

• Replace Spring.Net IoC with another Container (e.g. Ninject)

  - by Jeffrey Cameron

  Hey all, I'm curious to know if it's possible to replace Spring.Net's built-in IoC container with Ninject. We use Ninject on my team for IoC in our other projects so I would like to continue using that container if possible. Is this possible? Has anyone written a Ninject-Spring.Net Adapter?? Edit I like many parts of the Spring.Net package (the data access, transactions, etc.) but I don't really like the dependency injection container. I would like to replace that with Ninject Thanks

• Best practices for packaging resources (jpg's, sound, video) in an iPhone app?

  - by Mel

  I'm a newb iPhone developer writing an app that has several large JPGs and sound files. Everything works ok if I drag these non-code resources into my project. But I am wondering if this is the right way to package my app. In Windows development, I would create a "resource DLL" that keeps the .exe size small. What is the equivalent for iPhone? I think I should be creating a "bundle" - can someone please give me some pointers to using these and how to link them into my main project? Thanks!

• .resx file data inaccessible in Visual C#

  - by dsp_099

  What I'm trying to do: include some files along with the executable to extract them later. I have two projects, both with a Resource1.resx file (and some resources included from disk). In one project, I can use File.WriteAllBytes(path, Resource1.Image); to dump the resource to disk. In another, Resource1 is does not exist. I've done this before but all I can find is information about localizations (?) when I search MSDN for how to work with Resources.

• Strange problem installing a setup that I have just created.

  - by robUK

  Hello, I have both VS 2005 and 2008 installed. Just today I created a setup project in 2005 and I got this error when I tried to installed it. "The folder path 'http://sharingcentre.info' contains an invalid character." So I decided to create a simple project and added a new setup in 2005 and got the same problem. I then converted the project to 2008 and added another new setup. The same problem happened again. However, a previous setup project I created before work ok. I can install my application. Its only from today I cannot install any of my new setup projects. Using either 2005 and 2008. Has anyone else had this same problem. Searching google doesn't give me any real responses, I give the error message is too vague. many thanks for any suggestions,

• Why I should use an N-Tier Approach When using an SqlDatasource is ALOT EASIER ?

  - by The_AlienCoder

  When it comes to web development I have always tried to work SMART not HARD. So for along time My Aproach to interacting with databases in my AspNet projects has been this : 1) Create my stored procedures 2) Drag an SQLDatasource control on my aspx page 3) Bind a DataList Control to my SQLDatasource 4) Insert, Update & Delete by using my Datalist or programmatically using built in SQLDatasource methods e.g MySqlDataSource.InsertParameters["author"].DefaultValue = TextBox1.Text; MySqlDataSource.Insert(); Recently however I got a relatively easy web project. So I decided to employ a 3-tier Model...But I got exhausted halfway and just didnt seem worth it ! It seemed like I was working too HARD for a project that could have been easily accomplished by a couple of SqlDataSource Controls. So Why Is the N-Tier Model better than my Approach? Has it anything to do with performance? What are the advantages of the ObjectDataSource control over the SqlDataSource Control?

• Hosting Private Git repos on my own server?

  - by Stoic

  Hey, I am looking for a way to host private git repos on my own server. I am using Github for Open source projects of mine, but I would prefer to use my own server for storing private git repos. Can someone suggest me on which script should I be using for this purpose. Trac is not what I am looking for, though. I want something that is, preferably PHP based solution (just optional) and esp. something that has an easier UI. Any help is appreciated here.

• (UNITY3D) Get slerp to work just as LookAt(,Vector3.right) does

  - by Ben Rokah

  Ive been working over a sidescroller shooter game. Ive got my sidescroller shooter character to look around with these : chest.LookAt(mousepos,Vector3.right); & chest.LookAt(mousepos,Vector3.left); (Left when the character is turned to the left and right when the character is turned to the right) so it wont aim in to any other axis... But when the mouse gets to cross the middle of the character and not around it it gets the rotation to make a small transportation between frames and it wont get all the way to there.. It'll just teleport to its correct rotation like lookat should. Well the question is, how do I get any quaternion slerp which works with a Time.deltTime to work as same as LookAt(,Vector3.right)? I must have the Vector3.right and left so it'll move trough 1 axis. Many thanks to anyone who helps me out. :)

• jQuery: using hover to roll-over multiple images at once.

  - by WillKop

  I have a small problem, but I'm a bit stumped. I am using the following code to do rollovers on my webpage $("#mylink1 img").hover( function() { this.src = this.src.replace("_off","_on"); }, function() { this.src = this.src.replace("_on","_off"); } ); This works great for individual images, but I would like to roll over one of them and have the the other one change as well. <a id="mylink1" href="about.cfm"><img src="images/Home_top_navs/aboutus_manage_off.gif" /></a> <a id="mylink1" href="about.cfm"><img src="images/Home_top_navs/aboutus_nav2_off.gif" /></a> Any help would be appreciated!

• Project works in eclipse but not when exported

  - by Mike

  I wrote an application that uses GraphViz to generate some graphs as .gif's according to the DOT syntax. When I run from Eclipse the images are generated fine but when I export it as a jar the images are created but there is no data in them. When I view them in Microsoft Picture Viewer its just the red X. It was working as an exported jar until I put the picture generation in its own thread. I can't seem to figure out whats going on here. Are there any problems exporting multi-threaded projects? Any one have any ideas? Thanks

• Run and terminate a prgram (Python under Windows)

  - by Fredrich

  I'd like to create a small script to that basically does this: run program1.exe -- kill program1.exe after n seconds -- run program1.exe again. I know some basic Python and would read up on this, but I'm in a bit of a hurry and just need this to get done asap. If someone has a script/idea or could help my out with just the syntax I need to open and kill the .exe file, please... I don't mind solutions in other languages either. I'm sorry if this is a bit "please write my code"-ish, that's not something I typically do.

• Is it possible to take a half done web application that has been started using VB.NET and continue u

  - by John ClearZ

  A guy came to me there recently with a half done web app that has been created using VB.NET, nothing major, just a normal site. His original programmer couldn't continue so he wants me to finish it. Problem is I don't program using VB.NET nor have I any intention of learning it for a project this small. Usually I would run from something like this but I need the cash. Should I take the project and continue it using C# or just leave it. Has anyone had a similar experience and how did it turn out.
