  • https not redirecting to mongrel upstream

    - by kip
    Normal http is working fine for me with nginx and mongrel, however when i attempt to use https I am directed to the "welcome to nginx page". http { # passenger_root /opt/passenger-2.2.11; # passenger_ruby /usr/bin/ruby1.8; include mime.types; default_type application/octet-stream; #log_format main '$remote_addr - $remote_user [$time_local] "$request" ' # '$status $body_bytes_sent "$http_referer" ' # '"$http_user_agent" "$http_x_forwarded_for"'; #access_log logs/access.log main; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; upstream mongrel { server 00.000.000.000:8000; server 00.000.000.000:8001; } server { listen 443; server_name domain.com; ssl on; ssl_certificate /etc/ssl/localcerts/domain_combined.crt; ssl_certificate_key /etc/ssl/localcerts/www.domain.com.key; # ssl_session_timeout 5m; # ssl_protocols SSLv2 SSLv3 TLSv1; # ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP; # ssl_prefer_server_ciphers on; location / { root /current/public/; index index.html index.htm; proxy_set_header X_FORWARDED_PROTO https; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_pass http://mongrel; } } }

  • What is the fastest way to find duplicates in multiple BIG txt files?

    - by user2950750
    I am really in deep water here and I need a lifeline. I have 10 txt files. Each file has up to 100.000.000 lines of data. Each line is simply a number representing something else. Numbers go up to 9 digits. I need to (somehow) scan these 10 files and find the numbers that appear in all 10 files. And here comes the tricky part. I have to do it in less than 2 seconds. I am not a developer, so I need an explanation for dummies. I have done enough research to learn that hash tables and map reduce might be something that I can make use of. But can it really be used to make it this fast, or do I need more advanced solutions? I have also been thinking about cutting up the files into smaller files. To that 1 file with 100.000.000 lines is transformed into 100 files with 1.000.000 lines. But I do not know what is best: 10 files with 100 million lines or 1000 files with 1 million lines? When I try to open the 100 million line file, it takes forever. So I think, maybe, it is just too big to be used. But I don't know if you can write code that will scan it without opening. Speed is the most important factor in this, and I need to know if it can be done as fast as I need it, or if I have to store my data in another way, for example, in a database like mysql or something. Thank you in advance to anybody that can give some good feedback.

  • Compact data structure for storing a large set of integral values

    - by Odrade
    I'm working on an application that needs to pass around large sets of Int32 values. The sets are expected to contain ~1,000,000-50,000,000 items, where each item is a database key in the range 0-50,000,000. I expect distribution of ids in any given set to be effectively random over this range. The operations I need on the set are dirt simple: Add a new value Iterate over all of the values. There is a serious concern about the memory usage of these sets, so I'm looking for a data structure that can store the ids more efficiently than a simple List<int>or HashSet<int>. I've looked at BitArray, but that can be wasteful depending on how sparse the ids are. I've also considered a bitwise trie, but I'm unsure how to calculate the space efficiency of that solution for the expected data. A Bloom Filter would be great, if only I could tolerate the false negatives. I would appreciate any suggestions of data structures suitable for this purpose. I'm interested in both out-of-the-box and custom solutions. EDIT: To answer your questions: No, the items don't need to be sorted By "pass around" I mean both pass between methods and serialize and send over the wire. I clearly should have mentioned this. There could be a decent number of these sets in memory at once (~100).

  • How to check dates don't overlap in a table using TSQL.

    - by Jon
    I have a table with start and finish datetimes that I need to determine if any overlap and not quite sure the best way to go. Initially I was thinking of using a nested cursor as shown below which does work, however I'm checking the same records against each other twice and I'm sure it is not very efficient. eg: this table would result in an overlap. id start end ------------------------------------------------------- 1 2009-10-22 10:19:00.000 2009-10-22 11:40:00.000 2 2009-10-22 10:31:00.000 2009-10-22 13:34:00.000 3 2009-10-22 16:31:00.000 2009-10-22 17:34:00.000 Declare @Start datetime, @End datetime, @OtherStart datetime, @OtherEnd datetime, @id int, @endCheck bit Set @endCheck = 0 DECLARE Cur1 CURSOR FOR select id, start, end from table1 OPEN Cur1 FETCH NEXT FROM Cur1 INTO @id, @Start, @End WHILE @@FETCH_STATUS = 0 AND @endCheck = 0 BEGIN -- Get a cursor on all the other records DECLARE Cur2 CURSOR FOR select start, end from table1 and id != @id OPEN Cur2 FETCH NEXT FROM Cur2 INTO @OtherStart, @OtherEnd WHILE @@FETCH_STATUS = 0 AND @endCheck = 0 BEGIN if ( @Start > @OtherStart AND @Start < @OtherEnd OR @End > @OtherStart AND @End < @OtherEnd ) or ( @OtherStart > @Start AND @OtherStart < @End OR @OtherEnd > @Start AND @OtherEnd < @End ) BEGIN SET @endCheck = 1 END FETCH NEXT FROM Cur2 INTO @OtherStart, @OtherEnd END CLOSE Cur2 DEALLOCATE Cur2 FETCH NEXT FROM Cur1 INTO @id, @Start, @End END CLOSE Cur1 DEALLOCATE Cur1

  • Using multiple column layout with HTML 5 and CSS 3

    - by nikolaosk
    This is going to be the fourth post in a series of posts regarding HTML 5. You can find the other posts here , here and here.In this post I will provide a hands-on example with HTML 5 and CSS 3 on how to create a page with multiple columns and proper layout.I will show you how to use CSS 3 to create columns much easier than relying on DIV elements and the float CSS rule.I will also show you how to use browser-specific prefix rules (-ms for Internet Explorer and -moz for Firefox ) for browsers that do not fully support CSS 3.In order to be absolutely clear this is not (and could not be) a detailed tutorial on HTML 5. There are other great resources for that.Navigate to the excellent interactive tutorials of W3School.Another excellent resource is HTML 5 Doctor.Two very nice sites that show you what features and specifications are implemented by various browsers and their versions are http://caniuse.com/ and http://html5test.com/. At this times Chrome seems to support most of HTML 5 specifications.Another excellent way to find out if the browser supports HTML 5 and CSS 3 features is to use the Javascript lightweight library Modernizr.In this hands-on example I will be using Expression Web 4.0.This application is not a free application. You can use any HTML editor you like.You can use Visual Studio 2012 Express edition. You can download it here.I will create a simple page with information about HTML 5, CSS 3 and JQuery. This is the full HTML 5 code. <!DOCTYPE html><html lang="en">  <head>    <title>HTML 5, CSS3 and JQuery</title>    <meta http-equiv="Content-Type" content="text/html;charset=utf-8" >    <link rel="stylesheet" type="text/css" href="style.css">       </head>  <body>    <div id="header">      <h1>Learn cutting edge technologies</h1>      <p>HTML 5, JQuery, CSS3</p>    </div>    <div id="main">      <div id="mainnews">        <div>          <h2>HTML 5</h2>        </div>        <div>          <p>            HTML5 is the latest version of HTML and XHTML.

Find out which parts of HTML5 are already supported by your browser today and compare the results with other browsers.                      The HTML5 test does not try to test all of the new features offered by HTML5, nor does it try to test the functionality of each feature it does detect.

The layout is achieved with that CSS rule #main{        column-count:2;        column-gap:20px;        column-rule: 1px solid #000;        -moz-column-count: 2;        -webkit-column-count: 2;        -moz-column-gap: 20px;        -webkit-column-gap: 20px;        -moz-column-rule: 1px solid #000;        -webkit-column-rule: 1px solid #000; Do note the column-count,column-gap and column-rule properties. These properties make the two column layout possible.Please have a look at the picture below to see why I used prefixes for Chrome (webkit) and Firefox(moz).It clearly indicates that the CSS 3 column layout are not supported from Firefox and Chrome.   Finally I test my simple HTML 5 page using the latest versions of Firefox,Internet Explorer and Chrome. In my machine I have installed Firefox 15.0.1.Have a look at the picture below to see how the page looks  I have installed Google Chrome 21.0 in my machine.Have a look at the picture below to see how the page looks Have a look at the picture below to see how my page looks in IE 10.  My page looks the same in all browsers.

  • SQLServer 2008 FailOver and Load Balancing

    - by Jedi Master Spooky
    I have a project with a 2TB database ( 450.000.000 rows). I need to provide to the proyect a solution that gives FailOver and load Balacing, what do you recommend? We are going to use a NetApp Filer for the Data Files and for the File System of the Proyect. I read that SQl Clustering does not provide load balacing. If I cannnot have this feature and I have to go only to the FailOver what Server ( I presume that the key feature here is memory) would you recomend. We are adding 1.000.000 rows a day. Once the rows is inserted we are doing a lot of updates to that row for about 1 week then the row get static. Because of this I am thinking in some kind of history table or database or something like that. I am open to the Os servers implementation, I was thinking of a windows 2008 server with cluster but this depend of the database solution

  • Deployment Workbench no longer available after PXE boot

    - by Patrick
    Our build process revolves around windows Deployment Workbench. Unfortunately this was setup by someone who is no longer with the company, and no-one has ever dared/needed to make any changes. The other day it stopped working. It turns out that one of our build guys started thinking about changing some stuff in it, clicked something and now it no longer works (He is saying now that he right clicked on the 'LAB' entry in 'Deployment points' and hit 'Update', which took some time to run through apparently). The job has fallen on me to resolve and frankly I'm not sure what I'm doing. I was wondering if someone with more experience than me can provide some pointers as to troubleshooting cos I'm feeling quite a lot in the dark here. On the server I have Deployment Workbench up and running (MMC snapin) version 3.0. There is a WDS service that appears to be running ok, as does the tFTPd service. Nothing specific to this in event logs. From the client side; PXE boot works and gets you to the Win PE launch, and it has the correct company logo as the background (proving to me that its loading win PE from the network). WPEINIT runs, and asks for domain credentials, here the team simply put User/Pass/Domain in the boxes and click ok. Normally the build would kick off. Instead they get an error message saying that the \NATBLU01\Distribution$ share isn't available. Checking \NATBLU01\Distribution$ shows that its there and accessible over the network. Security/permissions seem ok, even 'ANONYMOUS LOGON' has read access to that share so I don't see that being a problem. Digging the trace files from C:\MININT\SMSOSD\OSDLOGS\ after an attempt to run the build I can see an error saying much the same - <![LOG[Validating connection to \\NATBLU01\Distribution$]LOG]!><time="16:42:14.000+000" date="03-15-2012" component="LiteTouch" context="" type="1" thread="" file="LiteTouch"> <![LOG[FindFile: The file OSDConnectToUNC.exe could not be found in any standard locations.]LOG]!><time="16:42:14.000+000" date="03-15-2012" component="LiteTouch" context="" type="1" thread="" file="LiteTouch"> <![LOG[The network location cannot be reached. For information about network troubleshooting, see Windows Help.]LOG]!><time="16:42:24.000+000" date="03-15-2012" component="LiteTouch" context="" type="3" thread="" file="LiteTouch"> <![LOG[ERROR - Unable to map a network drive to \\NATBLU01\Distribution$.]LOG]!><time="16:42:24.000+000" date="03-15-2012" component="LiteTouch" context="" type="3" thread="" file="LiteTouch"> BDD.LOG shows much the same. Full copies of the .LOG files can both files be found here : BDD.LOG LITETOUCH.LOG I can get to a command prompt from the Win PE that boots from PXE, however there isn't any network stuff there. IPCONFIG returns nothing so none of the tests I would usually run resolve anything. I'm at a loss frankly. I did wonder if I could perhaps start a new build process but if the change to the DeploymentWorkbench has knocked it offline I don't think I'm going to be able to create a new deployment. Failing that; we do have a deployment point labeled type 'Media' which appears to be a DVD ISO image of one of the builds, but its dated 2008, is it possible to export the network build to .ISO and build from DVD? We are looking at new hardware to run this from anyway (for the impending Windows 7 roll out) so a temporary work round isn't going to be too much of a problem. All assistance is appreciated! EDIT : OK. Got it working again. Solution was close to Newmanth's idea. The problem was that our PE image didn't appear to be connecting the network. I had an older copy of the PE boot.WIM on a stick that I had been using for other purposes. I booted that and correctly got a network connection. Showed a correct internal IP and could ping out etc etc. However I was still getting the same errors in all the logs and in when wpeinit was running. What I did seperately was to update the PE image that DeploymentWorkbench was pushing out to display a different back ground. I wanted to prove that I was working in the correct place. Turns out that I wasn't. I went and looked at the other deployment stuff we had on this machine, Windows Deployment Services was installed and although all the install images are off line the boot image was online, so I uploaded the copy from my stick to that. Booted straight off. And fixed. Working. Yay! For anyone stumbling across this in the future you may find that although your deployment images are located in the DeploymentWorkbench, the Win PE boot image you are launching from is located in the associated Windows Deployment Services images.

  • PPF Savings Interest Rate Increased To 8.6% From 8% [India]

    - by Gopinath
    Here is some good news to small Indian investors who save money in Public Provident Fund(PPF) accounts operated in Post Offices and few nationalized banks – returns of your PPF savings are going to increase. Indian government has decided to increase the rate of interest paid to customers from 8% to 8.6%. To put it in numbers, if you have a 2,00,000 of savings in PPF account they are going give returns of 17,200/- per annum compared to 16,000/- returns at 8%. Also the the maximum cap on the investments in to PPF account per annum is increased to 1,00,000 from 70,000/-. PPF is one of the safest debt investments that gives very decent returns, but if you are a salaried employee with PF account then consider investing in Voluntary PF(VPF) instead of PPF as VPF returns are higher than PPF.

  • How to set child unordered list position?

    - by Joel
    Hi folks. I have a nav bar with children unordered lists nested under the main navbar items. My problem is on the inner list, when I position absolute, the inner list is centered to the page, and when I position relative, it is positioning inline with the parent list. I'm trying to get the first child item to line up directly under it's parent. /* OUTER LIST STYLING */ div#navbar2 { position:relative; width: 100%; border-top: solid #000 1px; border-bottom: solid #546F8B 1px; background-color: #546F8B; } div#navbar2 ul#navbar { padding: 0; margin: 10px 0; font-family: Arial, Helvetica, sans-serif; font-size: 16px; letter-spacing:1px; color: #FFF; white-space: nowrap; } div#navbar2 ul#navbar li { margin: 0 2px; list-style-type: none; display: inline; } div#navbar2 li a { text-decoration: none; color: #fff; padding: 10px 10px; } div#navbar2 li a:link { color: #FFF: } div#navbar2 li a:visited { color: #ffffff; } div#navbar2 li a:hover { color: #000; background-color: #FDFFC9; } /* INNER LIST STYLING */ div#navbar2 ul#navbar li ul.innerlist{ display: none; color:#000; } div#navbar2 ul#navbar li ul.innerlist li{ color:#000; } div#navbar2 ul#navbar li:hover ul.innerlist { position: absolute; display: inline; left: 0; width: 100%; margin: 40px 0 0px 0px; padding: 0px; color:#000; } div#navbar2 li.innerlist a { text-decoration: none; color: #000; padding: 10px 10px; } div#navbar2 li.innerlist a:link { color: #000: } div#navbar2 li.innerlist a:visited { color: #000; } div#navbar2 li.innerlist a:hover { color: #000; background-color: #FDFFC9; } And my html: <div id="navbar2"> <ul id="navbar"> <li id="index"><a href="index.php">About Rattletree</a></li> <li id="upcomingshows"><a href="upcomingshows.php">Calendar</a></li> <li id="booking"><a href="booking.php">Contact</a> <ul class="innerlist"> <li class="innerlist"><a href="#">Booking</a></li> <li class="innerlist"><a href="#">press</a></li> </ul> </li> <li id="instruments"><a href="instruments.php">The Band</a> <ul class="innerlist"> <li class="innerlist"><a href="#">The Instruments</a></li> <li class="innerlist"><a href="#">The Players</a></li> </ul> </li> <li id="classes"><a href="classes.php">Sights &amp; Sounds</a> <ul class="innerlist"> <li class="innerlist"><a href="#">Listen</a></li> <li class="innerlist"><a href="#">photos</a></li> <li class="innerlist"><a href="#">video</a></li> </ul> </li> <li id"classes"><a href="classes.php">Workshops &amp; Classes</a></li> </ul> </div> Thanks for any help!

  • Used HDD/ran DiskSmartView/40,000 Power-on-hours?? should i trust it w/ my data, or take it back and bitch?

    - by David Lindsay
    I just bought a used hard drive from a University Surplus Store. Decided to run DiskSmartView to make sure it wasn't ready to fail. 40,000 power-on-hours I don't know if I feel like trusting my data to something that used. I really dont know if thats unreasonably old, but when i compare it to the POH reading i get when testing my other hdds its more than 3x older (my others have 2110 hours, 6150 hours, etc.. It's a Western Digital, so that gives me a little bit of hope(WDC WD4000KD-00NAB0). I could sure use someone else's opinion here. Thanks, DAVE

  • Div positioning problem related to Relative and Absolute positioning

    - by abszero
    Hello everyone. The problem I am running into is related to a footer I have absolutely positioned at the bottom of the page. Everything is fine until the copy on the page begins to extend further down the page which then causes my content wells to extend down, behind, the footer. Is there anyway I can force my content wells to 'push' the footer down the page? Here is the relevant html: <div id="page"> <div id="page_container"> <div id="header"></div> <div id="nav"></div> <div id="main_content"> <div id="left_column"></div> <div id="right_column"></div> </div> </div> </div> <div id="footer"> <div id="footer_container"> </div> </div> And the relevant CSS #page {width:100%;margin:0 0 10px 0; text-align:center;} #page_container {width:743px;height:auto !important;height:100%;margin:0 auto;min-height:100%;text-align:center;overflow:hidden;border:2px solid #000;} #header {width:100%;background:url('../images/header.jpg');height:87px;clear:both; margin-top: -2px;} #nav {width:100%;height:29px;float:left; text-align:left; border-bottom: solid 2px #000; border-top: solid 2px #000;} #main_content {width:100%;float:left; text-align:left; background-color:#fff; border-bottom: solid 2px #000; border-left: solid 2px #000; border-right: solid 2px #000;} #footer {width:100%; position:absolute;margin-top:10px; bottom: 0; background:url('../images/footer_bg.jpg');height:133px;text-align:center;} #footer_container{width:746px;height:133px; text-align:left; display:inline-block;} #left_column {width:230px; float:left; text-align:left; background-color:#fff; margin-top:5px;} #right_column {width:490px; float:right; text-align:left; background-color:#fff;margin-top:5px; padding:10px;} Thanks for any help you might be able to give!

  • Need events to execute on timer events, metronome precision.

    - by user295734
    I setup a timer to call an event in my application. The problme is the event execution is being skewed by other windows operations. Ex. openning and window, loading a webpage. I need the event to excute exactly on time, every time. When i first set up the app, used a sound file, like a metronome to listen to the even firing, in a steady state, its firing right on, but as soon do something in the windows environment, the sound fires slower, then sort of sppeds up a bit to catch up. So i added a logging method to the event to ctahc the timer ticks. From that data, it appears that the timer is not being affected by the windows app, but my application event calls are being affected. I figured this out by checking the datetime.now in the event, and if i set it to 250 milliseconds, which is 4 clicks per second. You get data something like below. (sec):(ms) 1:000 1:250 1:500 1:750 2:000 2:250 2:500 2:750 3:000 3:250 3:500 3:750 (lets say i execute some windows event)(time will skew) 4:122 4:388 4:600 4:876 (stop doing what i was doing in windows) (going to shorten the data for simplicit, my list was 30sec long) 5:124 5:268 5:500 5:750 (you would se the time go back the same milliseconds it was at the begining) 6:000 6:250 6:500 6:750 7:000 7:250 7:500 7:750 So i'm thinking the timer continues to fire on the same millisecond every time, but its the event that is being skewed to fire off time by other windows operations. Its not a huge skew, but for what i need to accomplish, its unacceptable. Is there anyhting i can do in .NET, hoping to use XAML/WPF application, thats will correct the skewing of events? thx.

  • Checking if an int is prime more efficiently

    - by SipSop
    I recently was part of a small java programming competition at my school. My partner and I have just finished our first pure oop class and most of the questions were out of our league so we settled on this one (and I am paraphrasing somewhat): "given an input integer n return the next int that is prime and its reverse is also prime for example if n = 18 your program should print 31" because 31 and 13 are both prime. Your .class file would then have a test case of all the possible numbers from 1-2,000,000,000 passed to it and it had to return the correct answer within 10 seconds to be considered valid. We found a solution but with larger test cases it would take longer than 10 seconds. I am fairly certain there is a way to move the range of looping from n,..2,000,000,000 down as the likely hood of needing to loop that far when n is a low number is small, but either way we broke the loop when a number is prime under both conditions is found. At first we were looping from 2,..n no matter how large it was then i remembered the rule about only looping to the square root of n. Any suggestions on how to make my program more efficient? I have had no classes dealing with complexity analysis of algorithms. Here is our attempt. public class P3 { public static void main(String[] args){ long loop = 2000000000; long n = Integer.parseInt(args[0]); for(long i = n; i<loop; i++) { String s = i +""; String r = ""; for(int j = s.length()-1; j>=0; j--) r = r + s.charAt(j); if(prime(i) && prime(Long.parseLong(r))) { System.out.println(i); break; } } System.out.println("#"); } public static boolean prime(long p){ for(int i = 2; i<(int)Math.sqrt(p); i++) { if(p%i==0) return false; } return true; } } ps sorry if i did the formatting for code wrong this is my first time posting here. Also the output had to have a '#' after each line thats what the line after the loop is about Thanks for any help you guys offer!!!
