  • Big and reaaaally strange problem with a web server (host InMotion Hosting)

    - by altar
    Hi. I have a terrible problem that I have tried to solve since three days ago: I browse my own web site and after a while I cannot access the web site. AT ALL! I can only see a 501 error message: "Method Not Implemented. GET to / not supported. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request." Once I get that error the site is totally and permanently inaccessible in that browser!! Reboot, browser restarts, clear cache, clear all history and cookies, etc., are not working. I have reproduced it in 4 different computers. Three computers are in one city, the 4th is in another city. Two different ISP's also. One computer is Linux, the others are on Windows (XP and 2000). Browsers are FF 3 to FF3.5 and IE 8. The error is ALMOST reproducible on demand (for me at least). It appears when I browse the forum under certain circumstances. I don't know which are these circumstances, but if I browse it long enough (10 sec to 5 minutes) it eventually appears. Just to make it clear, once the error appears (while browsing the forum) then the whole web site become inaccessible, not only the forum! My host is not willing to help because they say they cannot reproduce the error. I sent screenoshots but they don't care. NEWS Reseting browser's settings from the 'Tools-Clear private data' din't worked. However! When I have cleared the same settings (more exaclty) cookies from the special menu that appears when you right click website's icon, it worked. So it was something related to a cookie BUT it manifests in all browsers (FF, IE, Opera). So it cannot be a browser related problem.

  • Good bitmap fonts with big sizes and unicode support

    - by bitonic
    I really like bitmap fonts for programming/terminal. As far as I know there are two bitmap fonts with good unicode support: Unifont Fixed The problem is that I have a really high resolution screen, and they're both too small. Fixed does include a large size (10x20) but it looks really bad (it's basically always bold, and bold is a different face). Are there any other bitmap fonts with unicode support and large sizes? Terminus is the only font with a decent size but it doesn't have good unicode support. Having good coverage for mathematical symbols would be enough, since that's what I need.

  • Securing internal data accessed by a website on the big, bad internet

    - by aehiilrs
    A close relative of this question on Stack Overflow: When you have a web site in your DMZ that needs to access production data stored on an internal DB, what strategies do you recommend using to lower the risks that come from accessing live data? Is it even considered acceptable to have a connection initiated from the DMZ come inside of your network? An extra detail about the nature of the site that kind of throws a monkey wrench into the machinery is that people using the web site will be competing for "spots" on a first-come, first-serve basis with others using the internal software. Because of this, as close to zero lag time between the two applications as possible is ideal.

  • How to view big files on Windows?

    - by user20988
    Sometimes we need to view large files - 30M-100M. Usually we use FAR viewer for this. Sometimes we need to copy to clipboard long traces from this file. But it is possible to copy only one screen in FAR viewer. What can be used for this purpose? It should be GUI and freeware. UPDATE: We need to have ability navigate over the file and see updates of the file in the meantime (eg tail -f)

  • Question about server usage, big community platform [closed]

    - by Json
    Possible Duplicate: How do you do Load Testing and Capacity Planning for Web Sites I’m working on a community platform writen in PHP, MySQL. I have some questions about the server usage maybe someone can help me out. The community is based on JQuery with many ajax requests to update content. It makes 5 - 10 AJAX(Json, GET, POST) requests every 5 seconds, the requests fetch user data like user notifications and messages by doing mySQL queries. I wonder how a server will handle this when there are for more than 5000 users online. Then it will be 50.000 requests every 5 seconds, what kind of server you need to handle this? Or maybe even more, when there are 15.000 users online, 150.000 requests every 5 seconds. My webserver have the following specs. Xeon Quad 2048MB 5000GB traffic Will it be good enough, and for how many users? Anyone can help me out or know where to find such information, like make a calculation?

  • Finding usage of jQuery UI in a big ugly codebase

    - by Daniel Magliola
    I've recently inherited the maintenance of a big, ugly codebase for a production website. Poke your eyes out ugly. And though it's big, it's mostly PHP code, it doesn't have much JS, besides a few "ajaxy" things in the UI. Our main current problem is that the site is just too heavy. Homepage weighs in at 1.6 Mb currently, so I'm trying to clean some stuff out. One of the main wasters is that every single page includes the jQuery UI library, but I don't think it's used at all. It's definitely not being used in the homepage and in most pages, so I want to only include the where necessary. I'm not really experienced with jQuery, i'm more of a Prototype guy, so I'm wondering. Is there anything I could search for that'd let me know where jQuery UI is being used? What i'm looking for is "common strings", component names, etc For example, if this was scriptaculous, i'd look for things like "Draggable", "Effect", etc. Any suggestions for jQuery UI? (Of course, if you can think of a more robust way of removing the tag from pages that don't use it without breaking everything, I'd love to hear about it) Thanks!! Daniel

  • Cairo / GTK example code crashes when window is too big or maximized

    - by user1890673
    I have copied and compiled the source code available in the section titled "Full Source". http://cairographics.org/threaded_animation_with_cairo/ I adapted this code to a project that I'm working on only to find that the app would crash when I made the window too big. Going back to the original example code, it too crashes when the window is too big ( 1000x1000 or so). I narrowed down in the example that this line appears to be responsible: pixmap = gdk_pixmap_new(window-window,500,500,-1); Where pixmap is of type GdkPixmap*. Resizing the window overwrites pixmap with a new pixmap that is the size of the window. I am doing this in Eclipse Juno in Windows Vista, 32-bit. My compiler is MinGW version 0.5-beta-20120426-1. My GTK+ version is 2.24.10 and apparently Cairo is 1.10.2 I added all of the includes and libraries for GTK and also added compiler switch -mms-bitfields. Is there a limit to the size of a pixmap or something? I'm just starting with GTK with examples so I'm not sure where to go if this example doesn't work.

  • 301 redirect Rule For Load Balance F5 BigIp

    - by Kshah
    I have a load balancer F5 Big ip for my website. Currently, I am having 302 redirect in place; however, I wanted to apply 301 but dont know how. For example: My website (abc.com) when typed 302 redirects to abc.com/index and when typed www.abc.com 302 redirects www.abc.com/index. I wanted to have a rule which will help me in abc.com - 301 redirect - www.abc.com/index abc.com/index - 301 redirect - www.abc.com/index www.abc.com - 301 redirect - www.abc.com/index Below is the code that my tech person is trying: Redirect to WWW when HTTP_REQUEST { if { [HTTP::host] equals "abc.com" or [HTTP::host] equals "abc.co.in" or [HTTP::host] equals "www.abc.co.in" } { if {!( [HTTP::path] equals "/")} { HTTP::respond 301 Location "http://www.abc.com[HTTP::path]" } } } Redirect POST when HTTP_REQUEST { if { [HTTP::method] equals "POST" } { persist source_addr pool shop_shop_vr4_http } } Redirect-VR4 HOMEPAGE when HTTP_REQUEST { if { [HTTP::path] equals "/" or [HTTP::path] starts_with "/target/" or [HTTP::path] starts_with "/logs/" or [HTTP::path] starts_with "/config/" } { HTTP::redirect "http://[HTTP::host]/index.jsp.vr" } }

  • Is there a user-comfortable Unix-like OS?

    - by Rob Kam
    Apparently BSD is like this but only for the OS not for the third party applications: Is there a Unix or Unix-like operating system (but not OS X), where all the installed applications and drivers either all work smoothly/properly or are not included in the distribution? But not something that's been dumbed down.

  • Predictive vs Least Connection Load Balancing Techniques

    - by Mani
    I have a windows based desktop application that communicates via TCP to the application servers. (windows 2003). No sticky sessions between client calls. We have exactly 2 servers to load balance and we are thinking to use a F5 hardware NLB. The application is a heavy load types, doing not much bussiness logic in the services but retrieving quite a big amount of data at most of the times. May be on an average 5000 to 10000 records at all times. Used mainly for storing and retirieving data and no special processing of data or calculations running on the server side. I am favouring 'predictive' considering my services take a while at times to return data and hence tracking the feedback would yield some better routing as in predictive. I am not sure if the given data is sufficient enough to suggest some ideas but considering these, what would be some suggestions\things to consider\best between Predictive and Least Connections ? Thanks.

  • F5 BigIP upgrade from 9.x to 10.x

    - by mbuk2k
    Having a few difficulties upgrading a Big IP 3400 from 9.4.8 to any version 10.x image. The following are the versions I've tried: 10.1.0.3341.0 10.2.2.763.3 10.2.3.112.0 10.2.4.577.0 To upgrade I'm running the following command: image2disk --format=volumes BIGIP-10.1.0.3341.0.iso Obviously replacing the version number with the relevant image I'm trying to upgrade to each time. The F5 reboots, and starts copying packages however after 30 seconds or so just stops copying. The cursor in the console is still flashing but no matter how long it's left, the package doesn't copy. It seems to be a different package with each version/image (but always the same package per version) at point of freezing, which I'm guessing is suggesting a space issue? I've checked free space on the device and it has over 2GB free at root which should surely be enough? If anyone has any advice or pointers, it would be kindly appreciated. Thank you

  • Why do some websites add "Slugs" to the end of URLs?

    - by Dave Webb
    Many websites, including this one, add what are apparently called slugs - descriptive but as far as I can tell useless bits of text - to the end of URLs. For example, the URL the site gives for this question is: http://stackoverflow.com/questions/47427/why-do-some-websites-add-slugs-to-the-end-of-urls But the following URL works just as well: http://stackoverflow.com/questions/47427/ Is the point of this text just to somehow make the URL more user friendly or are there some other benefits?

  • Htaccess rewrite rule .aspx to .php

    - by Markus Ossi
    Background: I have a website that has been built with ASP.NET 2.0 and is on Windows hosting. I now have to rewrite my site in PHP and move it into Linux hosting. I have a lot of incoming links to my site from around the web that point directly into the old .aspx-pages. The site itself is very simple, one dynamic page and five static ones. I saved the static .aspx pages as .php-pages and rewrote the dynamic page in PHP. The dynamic page is called City.aspx and I have written it in PHP and it is now called City.php. On my old Windows hosting, I used ASP.NET's URL mapping for friendly URL. For example, incoming URL request for Laajakaista/Ypaja.aspx was mapped into City.aspx?CityID=981. My goal: To redirect all human visitors and search engines looking for the old .aspx pages into the new .php pages. I am thinking that the easiest way to redirect visitors into new pages will be by making a redirect, where all requests for .aspx-files will be redirected into .php filetypes. So, if someone asks for MYSITE/City.aspx?CityID=5, they will be taken into MYSITE/City.php?CityID=5 instead. However, I am having a lot of trouble getting this to work. So far this is what I have found: rewriterule ^([.]+)\.aspx$ http://www.example.com/$1.php [R=301,L] However, I think this can not handle the parameters after the filetype and I am also not quite sure what to put on front. To make things a bit more complicated, at my previous site I used friendly URL's so that I had a huge mapping file with mappings like this: <add url="~/Laajakaista/Ypaja.aspx" mappedUrl="~/City.aspx?CityID=981" /> <add url="~/Laajakaista/Aetsa.aspx" mappedUrl="~/City.aspx?CityID=988" /> <add url="~/Laajakaista/Ahtari.aspx" mappedUrl="~/City.aspx?CityID=989" /> <add url="~/Laajakaista/Aanekoski.aspx" mappedUrl="~/City.aspx?CityID=992" /> I tried to make a simple redirect like this: Redirect 301 Laajakaista/Aanekoski.aspx City.php?CityID=992 but was not able to get it to work. I ended up with an internal server error and a 50k .htaccess-file... Any help is greatly appreciated.

  • Writing a Javascript library that is code-completion and code-inspection friendly

    - by Vivin Paliath
    I recently made my own Javascript library and I initially used the following pattern: var myLibrary = (function () { var someProp = "..."; function someFunc() { ... } function someFunc2() { ... } return { func: someFunc, fun2: someFunc2, prop: someProp; } }()); The problem with this is that I can't really use code completion because the IDE doesn't know about the properties that the function literal is returning (I'm using IntelliJ IDEA 9 by the way). I've looked at jQuery code and tried to do this: (function(window, undefined) { var myLibrary = (function () { var someProp = "..."; function someFunc() { ... } function someFunc2() { ... } return { func: someFunc, fun2: someFunc2, prop: someProp; } }()); window.myLibrary = myLibrary; }(window)); I tried this, but now I have a different problem. The IDE doesn't really pick up on myLibrary either. The way I'm solving the problem now is this way: var myLibrary = { func: function() { }, func2: function() { }, prop: "" }; myLibrary = (function () { var someProp = "..."; function someFunc() { ... } function someFunc2() { ... } return { func: someFunc, fun2: someFunc2, prop: someProp; } }()); But that seems kinda clunky, and I can't exactly figure out how jQuery is doing it. Another question I have is how to handle functions with arbitrary numbers of parameters. For example, jQuery.bind can take 2 or 3 parameters, and the IDE doesn't seem to complain. I tried to do the same thing with my library, where a function could take 0 arguments or 1 argument. However, the IDE complains and warns that the correct number of parameters aren't being sent in. How do I handle this?

  • Which is more user friendly: TortoiseGIT or TortoiseHG?

    - by hamishmcn
    I have been experimenting with using Mercurial and TortoiseHG to track my work when I am working remotely (with a slow VPN I don't want to commit to SVN unless I have something that works). I have found TortoiseHG a bit hard to use - or at least it often doesn't work the way I expect it to, so I am considering switching to GIT and TortoiseGIT. (For example I had problems rolling back source code to an earlier version and I still don't know what I did wrong) My question whether they have a similar level of functionality / user friendliness or whether one is better than the other. What has your experience been?

  • Best way to create SEO friendly URI string

    The method below allows only "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ-" chars in URI strings. What better way is there to make nice SEO URI string? import org.apache.commons.lang.StringUtils; public static String safeChar(String input) { input = input.trim(); input = StringUtils.replace(input, " -", "-"); input = StringUtils.replace(input, "- ", "-"); input = StringUtils.replace(input, " - ", "-"); input = StringUtils.replaceChars(input, '\'', '-'); input = StringUtils.replaceChars(input, ' ', '-'); char[] allowed = "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ-".toCharArray(); char[] charArray = input.toCharArray(); StringBuilder result = new StringBuilder(); for (char c : charArray) { for (char a : allowed) { if (c == a) result.append(a); } } return result.toString(); }

  • Efficient Context-Free Grammar parser, preferably Python-friendly

    - by Max Shawabkeh
    I am in need of parsing a small subset of English for one of my project, described as a context-free grammar with (1-level) feature structures (example) and I need to do it efficiently . Right now I'm using NLTK's parser which produces the right output but is very slow. For my grammar of ~450 fairly ambiguous non-lexicon rules and half a million lexical entries, parsing simple sentences can take anywhere from 2 to 30 seconds, depending it seems on the number of resulting trees. Lexical entries have little to no effect on performance. Another problem is that loading the (25MB) grammar+lexicon at the beginning can take up to a minute. From what I can find in literature, the running time of the algorithm used to parse such a grammar (Earley or CKY) should be linear to the size of the grammar and cubic to the size of the input token list. My experience with NLTK indicates that ambiguity is what hurts the performance most, not the absolute size of the grammar. So now I'm looking for a CFG parser to replace NLTK. I've been considering PLY but I can't tell whether it supports feature structures in CFGs, which are required in my case, and the examples I've seen seem to be doing a lot of procedural parsing rather than just specifying a grammar. Can anybody show me an example of PLY both supporting feature structs and using a declarative grammar? I'm also fine with any other parser that can do what I need efficiently. A Python interface is preferable but not absolutely necessary.

  • Are All Dynamic Languages Typo-friendly?

    - by yar
    With Java on one side and Ruby/Groovy on the other, I know that in the second camp I'm free to make typos which will not get caught until run-time. Is this true of all dynamically-typed languages? Edit: I've been asked to elaborate on the type of typo. In Ruby and in Groovy, you can assign to a variable with an accidental name that is never read. You can call methods that don't exist (obviously your tests should catch this, it's been said). You can refer to classes that don't exist, etc. etc. Basically any valid syntax, even with typographical errors, is valid in both Ruby and Groovy.

  • how to combine widget webapp framework with SEO-friendly CSS and JS files

    - by Ali
    Hi guys, I'm writing a webapp using Zend framework and a homebrew widget system. Every widget has a controller and can choose to render one of many views if it chooses. This really helps us modularize and reconfigure and reuse the widgets anywhere on the site. The Problem is that the views of each widget contain their own JS and CSS code, which leads to very messy HTML code when the whole page is put together. You get pockets of style and script tags everywhere. This is bad for a lot of different reasons as I'm sure you know, but it has a profound effect on our SEO as well. Several solutions that I've been able to come up with: Separate the CSS and JS of every view of every widget into its own file - this has serious drawbacks for load times (many more resources have to be loaded separately) and it makes coding very difficult as now you have to have 3-4 files open just to edit a widget. combine the all the widget CSS into a single file (same with JS) - would also lead to a massive load when someone enters the site, mixes up the CSS and the JS for all widgets so it's harder to keep track of them, and other problems that I'm sure you can think of. Create a system that uses method 1 (separate CSS and JS for every widget), when delivering the page, stitches all CSS and JS together. This obviously needs more processing time and of course the creation of such a system, etc. My Question is what you guys think of these solutions or if there are pre-existing solutions that you know of (or any tech that might help) solve this problem. I really appreciate all of your thoughts and comments!! Thanks guys, Ali

  • .Net friendly, local, key-value pair, replicatable datastore

    - by Brad Mathews
    I am looking for a key/value type datastore with very specific requirements. Anyone know anything that will work? Needs to be a component of some sort. No additional installation needed. The datastore needs to be on the local hard drive. I am using VB.Net for a desktop app running Windows XP through 7 so it needs to callable by that environment. It needs to replicatable. If I have four copies of my app running on the network, each local copy of the datastore needs to replicate with the others. As close to real time as possible. The first three are easy, I can do that with ADO.Net out of the box. The last one, replication, is the one I do not have answer to. Does such an animal exist? Thanks, Brad

  • [C# asp.net mvc or javascript] user-friendly xml sensitization library that html encoding invalid pa

    - by Fox
    I would like to allow my users to submit a subset of xhtml that will be displayed to other users (likely I'll build a schema for it) but I want the server to handle validation more gracefully then hard rejecting invalid submissions.... Instead I'd like the server to Html Encode invalid/harmful parts of the submissions.... (sanitize javascript and css etc.) Is there any library (maybe asp.net mvc 2 has such functionality?) or do I have to develop my own? or maybe there is a javascript library that html encodes invalid parts and I can just have the server only accept that subset?
