Any advice on how to trace my own path to good python skills? thanks. PS: I will use vim, ypython and http://diveintopython.org

  • My home box as my own host?

    - by Majid
    Hi all, I have a 512 kb/s DSL service at home. I do not have a static IP but I can get one if I pay some extra to my ISP. Now, if I get the static IP, can I make my home box act as my internet host? What else do I need? Thanks P.S. I know that if at all possible, the site I make available this way might be slow, that is alright, my question is if it is possible at all. Edit: I need this for very small traffic. I am a php developer and for my projects I am often asked to provide a demo. I currently use a free hosting for this purpose but it is down most of the time and support is non-existent. So I thought to set-up my home computer as my test server. With this please note that: I will only occasionally have 'visitors' and that will be one or possibly two visitors at any time. These demos, are to showcase functionality, so no big images are served and page views will normally generate under 100KB of traffic.

  • Suddenly can't send E-Mails with Apple Mail to Gmail SMTP

    - by slhck
    Hi all, I have a weird problem that started just today. I am using Apple Mail on a Leopard machine, connecting to Gmail. Fetching e-mail works just fine. My SMTP settings are also correct. Still, I can't send mail, it will display a pop up saying that "transferring the content to the mail server" failed (translation from German, could be different in English OS X versions). I have verified the following: My SMTP settings are definitely correct. I have not changed them and the issue appeared today. Also, I went through the Apple online configuration for Gmail accounts and did not have to adjust any setting. I can run network diagnosis and it will connect to both POP and SMTP servers without a problem (all green lights) The Telnet details will show me the HELO message from the Gmail servers, so there's no authentication failure. Console.app will not show any messages related to "mail" when I try to send the mail, so there's no specific error message The mail I'm trying to send does not have an attachment, it is plaintext only I can login to gmail.com and send mails without a problem The recipient address exists and contains no syntax errors I can also not send mails to myself When using another IP and ISP (through VPN), it still doesn't work As for my settings: I connect to smtp.gmail.com and for advanced settings I choose password-based authentication with user: [email protected] and my password. I let Apple Mail try the default ports (for SSL and TLS, respectively). Again: I have not changed a thing between yesterday and today. What is causing that strange behavior? Any help would be much appreciated.

  • PHP Image Upload object won't create directory on windows

    - by ThinkingInBits
    I'm writing a class that excepts a product_id and a $_FILES array as it's constructor. The class saves these variables and uses them to create a new directory named by product_id and attempts to copy the temp file to my specified directory. For some reason my class isn't even getting as far as creating a directory (which should happen in the constructor) Here's a link to my code: http://pastie.org/955454

    I'm looking for an implementation preferably in Java of an algorithm for finding a Minimum Equivalent Graph of a Digraph (http://portal.acm.org/citation.cfm?id=321526.321534). Even better would be an implementation of "Approximating the minimum equivalent digraph" http://cat.inist.fr/?aModele=afficheN&cpsidt=3634076 (requires ACM membership, sorry) alternative link http://www.cs.umd.edu/~samir/grant/kry94b.ps (postscript)

  • where to find Ubercart translation files

    I am trying to update language specific text files ("po files") for Ubercart, but it is unclear who/where these files are maintained. There are several places sited but I am not sure which is maintained? http://ftp.drupal.org/files/translations/6.x/ubercart/ http://l10n.privnet.biz/translation_group/ Also a description of how to do this in Drupal. In Drupal (link: admin/build/translate/import) there are several text groups to select. Do I have to repeat update for each group?

  • PHP script loading took over 10 seconds

    - by Misiur
    My again. I've promised to not come back today, but I've got another trouble. http://www.misiur.com/me/ - it took over 10 seconds to load. Whole site code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="pl" lang="pl"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>{site('title')}</title> <link rel="stylesheet" type="text/css" href="{site('themeDir')}/global.css" /> </head> <body> <div id="site"> <div id="footer"> <p>Site Managment System {site('version')} by <a href="http://www.misiur.com">Misiur</a>.

I think that I've messed up. Help.

  • OPS4j repository alternative

    - by Paul Whelan
    The OPS4J repository is down at present and I am trying to run pax-provision using a profile for spring-dm. My question is how do I tell maven to locate the profile information from a site other than ops4j.org. Is this possible? ideally I would like to cache all the packages from the repo especially the spring-dm details which seem never to be cached and are downloaded all the time making coding on the train and times when the site is down impossible. Thanks Paul

  • Why doesn't my form post when I disable the submit button to prevent double clicking?

    - by John MacIntyre
    Like every other web developer on the planet, I have an issue with users double clicking the submit button on my forms. My understanding is that the conventional way to handle this issue, is to disable the button immediately after the first click, however when I do this, it doesn't post. I did do some research on this, god knows there's enough information, but other questions like Disable button on form submission, disabling the button appears to work. The original poster of Disable button after submit appears to have had the same problem as me, but there is no mention on how/if he resolved it. Here's some code on how to repeat it (tested in IE8 Beta2, but had same problem in IE7) My aspx code <%@ Page Language="C#" CodeFile="Default.aspx.cs" Inherits="_Default" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <script language="javascript" type="text/javascript"> function btn_onClick() { var chk = document.getElementById("chk"); if(chk.checked) { var btn = document.getElementById("btn"); btn.disabled = true; } } </script> <body> <form id="form1" runat="server"> <asp:Literal ID="lit" Text="--:--:--" runat="server" /> <br /> <asp:Button ID="btn" Text="Submit" runat="server" /> <br /> <input type="checkbox" id="chk" />Disable button on first click </form> </body> </html> My cs code using System; public partial class _Default : System.Web.UI.Page { protected override void OnInit(EventArgs e) { base.OnInit(e); btn.Click += new EventHandler(btn_Click); btn.OnClientClick = "btn_onClick();"; } void btn_Click(object sender, EventArgs e) { lit.Text = DateTime.Now.ToString("HH:mm:ss"); } } Notice that when you click the button, a postback occurs, and the time is updated. But when you check the check box, the next time you click the button, the button is disabled (as expected), but never does the postback. WHAT THE HECK AM I MISSING HERE??? Thanks in advance.

  • Setting Cookie Port

  • Parallels Plesk returning strange numbers

    - by Jack W-H
    Hi everyone, As a relatively new Server Admin I've become a bit confused by some statistics Parallels Plesk Panel 10.0.1 is returning to me. I have a domain ('subscription') set up, mysite.com. Mysite.com only hosts files, mostly images Its file contents use up about 390MB of disk space Here's a screenshot: this is what Plesk is reporting mysite.com to use: And some more info: Now this is pretty confusing... I thought at first my site might have been hacked and had contents written to disk, but I checked and all is in order, nothing has been hacked into as far as I can tell. So I had a look in the site's CP for some more in-depth statistics, and this is what's returned... Now - sod's law - when I go to check my disk space statistics in more depth via the control panel, this morning it says "The data were not collected yet." - not too sure what that means, but, last night when I checked it was reporting something odd. It said Files were using up 390MB, but 1.80GB or so were being used up by 'Mail Accounts'. This is really strange, as there are no mail accounts set up for the domain. The only hint of 'mail' there is, is the catchall set up to forward *@mysite.com to a separate, ISP-hosted email account. Any ideas anybody? I can post more details if you need it. Sorry to be a bit vague but I'm not sure what else I can post. Thanks, Jack

  • log4j performance

    - by Bob
    Hi, I'm developing a web app, and I'd like to log some information to help me improve and observe the app. (I'm using Tomcat6) First I thought I would use StringBuilders, append the logs to them and a task would persist them into the database like every 2 minutes. Because I was worried about the out-of-the-box logging system's performance. Then I made some test. Especially with log4j. Here is my code: Main.java public static void main(String[] args) { Thread[] threads = new Thread[LoggerThread.threadsNumber]; for(int i = 0; i < LoggerThread.threadsNumber; ++i){ threads[i] = new Thread(new LoggerThread("name - " + i)); } LoggerThread.startTimestamp = System.currentTimeMillis(); for(int i = 0; i < LoggerThread.threadsNumber; ++i){ threads[i].start(); } LoggerThread.java public class LoggerThread implements Runnable{ public static int threadsNumber = 10; public static long startTimestamp; private static int counter = 0; private String name; public LoggerThread(String name) { this.name = name; } private Logger log = Logger.getLogger(this.getClass()); @Override public void run() { for(int i=0; i<10000; ++i){ log.info(name + ": " + i); if(i == 9999){ int c = increaseCounter(); if(c == threadsNumber){ System.out.println("Elapsed time: " + (System.currentTimeMillis() - startTimestamp)); } } } } private synchronized int increaseCounter(){ return ++counter; } } } log4j.properties log4j.logger.main.LoggerThread=debug, f log4j.appender.f=org.apache.log4j.RollingFileAppender log4j.appender.f.layout=org.apache.log4j.PatternLayout log4j.appender.f.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n log4j.appender.f.File=c:/logs/logging.log log4j.appender.f.MaxFileSize=15000KB log4j.appender.f.MaxBackupIndex=50 I think this is a very common configuration for log4j. First I used log4j 1.2.14 then I realized there was a newer version, so I switched to 1.2.16 Here are the figures (all in millisec) LoggerThread.threadsNumber = 10 1.2.14: 4235, 4267, 4328, 4282 1.2.16: 2780, 2781, 2797, 2781 LoggerThread.threadsNumber = 100 1.2.14: 41312, 41014, 42251 1.2.16: 25606, 25729, 25922 I think this is very fast. Don't forget that: in every cycle the run method not just log into the file, it has to concatenate strings (name + ": " + i), and check an if test (i == 9999). When threadsNumber is 10, there are 100.000 loggings and if tests and concatenations. When it is 100, there are 1.000.000 loggings and if tests and concatenations. (I've read somewhere JVM uses StringBuilder's append for concatenation, not simple concatenation). Did I missed something? Am I doing something wrong? Did I forget any factor that could decrease the performance? If these figures are correct I think, I don't have to worry about log4j's performance even if I heavily log, do I?

  • Very Slow DSL (ethernet) speed

    - by Abhijit
    I 'was' on opensuse 12.2 when my dsl speed was normal. Yesterday I switched from opensuse to ubuntu 12.04 and speed decreased. It came to range of 7-10-13-20-25-kbps. Then I switch to linux mint, and then to fedora. Still slow speed. When I was in ubuntu I disabled ipv6 but still no luck. Now I am in fedora but this time with DIFFERENT ISP. And still I am getting very slow sped. So my guess is this is nothing to do with os. What can be wrong? Is this problem of NIC? Does NIC speed decreases over time? Does NIC life ends over time as with keyboard or mouse? Help please All the os I used are 64 bit and my laptop is Compaq Presario A965Tu Intel Centrino DUal Core. Interesting thing to notice is I get normal speed while downloading torrent inside torrent client softwares. This slow speed issue applied to download from any web browser or installing software using terminal.

I try to find solutions on the source code, then I find seems there are setting that related to this: http://www.jedit.org/users-guide/buffersets.html but I didn't find the selection mentioned on my setting.

  • How to add some complex structure in multiple places in an XML file

    - by Guillaume
    I have an XML file which has many section like the one below: <Operations> <Action [some attributes ...]> [some complex content ...] </Action> <Action [some attributes ...]> [some complex content ...] </Action> </Operations> I have to add an <Action/> to every <Operations/>. It seems that an XSLT should be a good solution to this problem: <xsl:template match="Operations/Action[last()]"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> <Action>[some complex content ...]</Action> </xsl:template> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> My problem is that the content of my <Action/> contains some xPath expressions. For example: <Action code="p_histo01"> <customScript languageCode="gel"> <gel:script xmlns:core="jelly:core" xmlns:gel="jelly:com.niku.union.gel.GELTagLibrary" xmlns:soap="jelly:com.niku.union.gel.SOAPTagLibrary" xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:sql="jelly:sql" xmlns:x="jelly:xml" xmlns:xog="http://www.niku.com/xog" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <sql:param value="${gel_stepInstanceId}"/> </gel:script> </customScript> </Action> The ${gel_stepInstanceId} is interpreted by my XSLT but I would like it to be copied as-is. Is that possible? How?

  • MongoDB query against geospatial index with maxDistance fails from node.js client

    I want to query against a geospatial index in mongo-db (designed after this tutorial http://www.mongodb.org/display/DOCS/Geospatial+Indexing). So when I execute this from the shell everything works fine: db.sellingpoints.find(( { location : { $near: [48.190120, 16.270895], $maxDistance: 7 / 111.2 } } ); but the same query from my nodejs application (using mongoskin or mongoose), won't return any results until i set the distance-value to a very high number (5690) db.collection('sellingpoints') .find({ location: { $near: [lat,lng], $maxDistance: distance / 111.2} }) .limit(limit) .toArray(callback); Has someone any idea how to fix that?
