  • Dlink DWA-556 Access point fails to start on 2.6.35-25 while 2.6.35-24 works. How can I do this with >2.6.35-24?

    - by Azendale
    I'm using hostapd to run an access point with a Dlink DWA-556 wireless N card. However, I can no longer get it to start when I use kernels greater than 2.6.35-24. Here's a log where I ran the uname -a&&hostapd -c <configfile> on the different kernel versions.

  • Trois fondamentaux de JavaScript, par Jean-Pierre Vincent

    Après quelques années à écrire dans un langage, on finit facilement par oublier les premières difficultés que l'on avait rencontrées Nous allons explorer ici les trois notions fondamentales de JavaScript qui sont probablement les plus grosses sources de bogues, d'incompréhension et de frustration pour le développeur Web moyen. Et qui accessoirement sont la base d'une programmation plus évoluée par la suite.

  • What can Go chan do that a list cannot?

    - by alpav
    I want to know in which situation Go chan makes code much simpler than using list or queue or array that is usually available in all languages. As it was stated by Rob Pike in one of his speeches about Go lexer, Go channels help to organize data flow between structures that are not homomorphic. I am interested in a simple Go code sample with chan that becomes MUCH more complicated in another language (for example C#) where chan is not available. I am not interested in samples that use chan just to increase performance by avoiding waiting of data between generating list and consuming the list (which can be solved by chunking) or as a way to organize thread safe queue or thread-safe communication (which can be easily solved by locking primitives). I am interested in a sample that makes code simpler structurally disregarding size of data. If such sample does not exist then sample where size of data matters. I guess desired sample would contain bi-directional communication between generator and consumer. Also if someone could add tag [channel] to the list of available tags, that would be great.

  • Removing the contents of a Chan or MVar in a single discrete step

    - by Bill
    I'm writing a discrete simulation where request values from multiple threads accumulate in a centralized queue. Every n milliseconds, a manager wakes up to process requests. When the manager wakes up, it should retrieve all of the contents of the central queue in a single discrete step. While processing these, any client threads attempting to submit to the queue should block. When processing completes, the queue reopens and the manager goes back to sleep. What's the best way to do this? The retry behavior of STM isn't really what I want. If I use a Chan or MVar, there's no way to prevent clients from enqueuing additional requests during processing. One approach is to use an MVar as a mutex on a Chan holding the queue. Are there other ways to do this?

  • how to allocate array of channels in go

    - by eran
    Sorry for the novice syntax question. How do how create an array of channels in go? var c0 chan int = make(chan int); var c1 chan int = make(chan int); var c2 chan int = make(chan int); var c3 chan int = make(chan int); var c4 chan int = make(chan int); That is, replacing the above five lines in one array of channels of size 5? Many thanks.

  • How can I send out diff's of submitted changes to the entire project whenever someone commits a chan

    - by Alex
    I'd like to be able to send all the contributors working on a project a message whenever a commit is made. This way, everyone sees the contribution, and hopefully someone will take a look and spot bugs and whatnot. Furthermore, it provides our bosses with a nice and simple, if a little incomprehensible, way to get an idea of how the project is progressing. We're using Mercurial right now.

  • How to implement a counter when using golang's goroutine?

    - by MrROY
    I'm trying to make a queue struct that have push and pop functions. I need to use 10 threads push and another 10 threads pop data, just like i did in the code below. Questions : 1. I need to print out how much i have pushed/popped, but i don't know how to do that. 2. Is there anyway to speed up my code ? the code is too slow for me. package main import ( "runtime" "time" ) const ( DATA_SIZE_PER_THREAD = 10000000 ) type Queue struct { records string } func (self Queue) push(record chan interface{}) { // need push counter record <- time.Now() } func (self Queue) pop(record chan interface{}) { // need pop counter <- record } func main() { runtime.GOMAXPROCS(runtime.NumCPU()) //record chan record := make(chan interface{},1000000) //finish flag chan finish := make(chan bool) queue := new(Queue) for i:=0; i<10; i++ { go func() { for j:=0; j<DATA_SIZE_PER_THREAD; j++ { queue.push(record) } finish<-true }() } for i:=0; i<10; i++ { go func() { for j:=0; j<DATA_SIZE_PER_THREAD; j++ { queue.pop(record) } finish<-true }() } for i:=0; i<20; i++ { <-finish } }

  • Publish a software with copyright and license

    - by King Chan
    I just read some artical about publishing software and I am personally developing some random metero application at the moment. The artical were suggesting the software should have a publisher website. But what I have to put down in the publisher website to keep my copyright? Is it simply really just "Designed/Developed @ 2012 By King Chan" at the bottom of the site and software and is enough? Or do I have to even write a long paragraph of license/agreement said the user who download/use the software cannot copy the icon/functionality etc? (The Apple and Samsung things get me worry about CopyRight now....)

  • Dynamically add event to custom control (Confirm Message Box)

    - by Nyein Nyein Chan Chan
    I have created a custom cofirm message box control and I created an event like this- [Category("Action")] [Description("Raised when the user clicks the button(ok)")] public event EventHandler Submit; protected virtual void OnSubmit(EventArgs e) { if (Submit != null) Submit(this, e); } The Event OnSubmit occurs when user click the OK button on the Confrim Box. void IPostBackEventHandler.RaisePostBackEvent(string eventArgument) { OnSubmit(e); } Now I am adding this OnSubmit Event Dynamically like this- In aspx- <my:ConfirmMessageBox ID="cfmTest" runat="server" ></my:ConfirmMessageBox> <asp:Button ID="btnCallMsg" runat="server" onclick="btnCallMsg_Click" /> <asp:TextBox ID="txtResult" runat="server" ></asp:TextBox> In cs- protected void btnCallMsg_Click(object sender, EventArgs e) { cfmTest.Submit += cfmTest_Submit;//Dynamically Add Event cfmTest.ShowConfirm("Are you sure to Save Data?"); //Show Confirm Message using Custom Control Message Box } protected void cfmTest_Submit(object sender, EventArgs e) { txtResult.Text = "User Confirmed";//I set the text to "User Confrimed" but it's not displayed txtResult.Focus();//I focus the textbox but I got Error } The Error I got is- System.InvalidOperationException was unhandled by user code Message="SetFocus can only be called before and during PreRender." Source="System.Web" So, when I dynamically add and fire custom control's event, there is an error in Web Control. If I add event in aspx file like this, <my:ConfirmMessageBox ID="cfmTest" runat="server" OnSubmit="cfmTest_Submit"></my:ConfirmMessageBox> There is no error and work fine. Can anybody help me to add event dynamically to custom control? Thanks.

  • Advice for moving from custom domain hosted on blogspot to new custom domain on hosting provider [closed]

    - by Chan
    Need some advice :) a) Facts: 1. Currently, we have a blog www.thebigbigsky.net hosted on blogspot.com. The site has been up for around a year and google had cached some of the posts. 2. The idea for setting up the blog was to promote/share articles/write-up about personal development and self-growth, and also to offer counseling services related to them. 3. There is another subdomain - chinese.thebigbigsky.net hosting similar blog posts but in Chinese. This is hosted on blogspot as well. b) What we want to do: 1. We did some research on the internet and understood that, to make a website more popular, it is better to have a domain name that is related to the content of the site. Hence, in our case, a domain name containing "personal development" would be more ideal and easier for people to remember. 2. Hence, we are thinking to move away from blogspot to a meaningful new domain (example: personaldevelopmentwithxyz.com) and move all contents there. The new domain will be hosted on a hosting provider e.g. hostgator.com c) Here are the steps we have in mind: 1. Register the new domain (example: personaldevelopmentwithxyz.com) 2. Get a hosting provider hostgator.com 3. Setup a new site based on Wordpress, import all contents from existing blog to this new site - personaldevelopmentwithxyz.com. 4. Switch current blog back to thebigbigsky.blogspot.com 5. Switch DNS of www.thebigbigsky.net to point to the new site on hostgator.com 6. On hostgator.com, setup permanent redirect 301 of www.thebigbigsky.net to point to personaldevelopmetnwithxyz.com by following the tutorial mentioned here - http://www.blogbloke.com/migrating-redirecting-blogger-wordpress-htaccess-apache-best-method/ Questions: 1. Will it have major impact on the current google pagerank or SEO of thebigbigsky.net? As the site is not that popular, we assumed that the impact would not be a major one. 2. Is the domain personaldevelopmentwithxyz.com considered too long? (For SEO etc) 3. Steps c.4 and c.5 above - Will this work for our case? 4. How about the subdomain - chinese.thebigbigsky.net? We would like keep it as separate blog with the domain e.g. chinese.personaldevelopmentwithxyz.com 5. We added "facebook comments" to the existing post on www.thebigtbigsky.net and would not want to lose it. Will the comments still be there after we moved to the new domain? 6. Any better idea to do it? :) Thank you very much! regards, -chan

I escaped the slash in Java accordingly): /bin/grep -vP --regexp='^[0-9]+\t.*' /usr/local/apache-tomcat-6.0.18/work/Catalina/localhost/saccitic/237482319867147879_1271411421 Java Code: String filepath = "/path/to/file"; String options = "P"; String grepparams = "^[0-9]+\\t.*"; String greppath = "/bin/"; String[] localeArray = new String[] { "LANG=", "LC_COLLATE=C", "LC_CTYPE=UTF-8", "LC_MESSAGES=C", "LC_MONETARY=C", "LC_NUMERIC=C", "LC_TIME=C", "LC_ALL=" }; options = "v"+options; //Assign optional params if (options.contains("P")) { grepparams = "\'"+grepparams+"\'"; //Quote the regex expression if -P flag is used } else { options = "E"+options; //equivalent to calling egrep } proc = sysRuntime.exec(greppath+"/grep -"+options+" --regexp="+grepparams+" "+filepath, localeArray); System.out.println(greppath+"/grep -"+options+" --regexp="+grepparams+" "+filepath); inStream = proc.getInputStream(); The command is supposed to match and discard strings like these: 85295371616 Hi Mr Lee, please be informed that... My input file is this: 85aaa234567 Hi Ms Chan, please be informed that... 85292vx5678 Hi Mrs Ng, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 85aaa234567 Hi Ms Chan, please be informed that... 85292vx5678 Hi Mrs Ng, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 8~!95371616 Hi Mr Lee, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 852&^*&1616 Hi Mr Lee, please be informed that... 8529537Ax16 Hi Mr Lee, please be informed that... 85====ppq16 Hi Mr Lee, please be informed that... 85291234783 a3283784428349247233834728482984723333 85219299222 The commands works when I call it from inside bash (Results below): 85aaa234567 Hi Ms Chan, please be informed that... 85292vx5678 Hi Mrs Ng, please be informed that... 85aaa234567 Hi Ms Chan, please be informed that... 85292vx5678 Hi Mrs Ng, please be informed that... 8~!95371616 Hi Mr Lee, please be informed that... 852&^*&1616 Hi Mr Lee, please be informed that... 8529537Ax16 Hi Mr Lee, please be informed that... 85====ppq16 Hi Mr Lee, please be informed that... 85219299222 However, when I call grep again inside java, I get the entire file (Results below): 85aaa234567 Hi Ms Chan, please be informed that... 85292vx5678 Hi Mrs Ng, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 85aaa234567 Hi Ms Chan, please be informed that... 85292vx5678 Hi Mrs Ng, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 8~!95371616 Hi Mr Lee, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 852&^*&1616 Hi Mr Lee, please be informed that... 8529537Ax16 Hi Mr Lee, please be informed that... 85====ppq16 Hi Mr Lee, please be informed that... 85291234783 a3283784428349247233834728482984723333 85219299222 What could be the problem that will cause the grep called by Java to return incorrect results? I tried passing local information via the environment string array in runtime.exec, but nothing seems to change. Am I passing in the locale information incorrectly, or is the problem something else entirely?
