  • Two routers, one off-site, same ISP-assigned static IP. A recipe for conflict?

    - by boost
    This is the situation I've inherited: There are two routers, one off-site. Both are connected to the ISP. The ISP assigns both of them the same static IP (or so it seems). Presumably, the network problems we're having are related to the idea that you can't have two instances of the same IP. So we rang up the folk off-site and told them to turn off the router. Now everything's working okay here. How do I get around this? Get another static IP? Figure out how to get the router to ask for a dynamic IP (as we're not using the static IP for anything)?

  • Why does jQuery do this in its constructor function implementation?

    - by mattcodes
    If we look at the latest jQuery source at http://code.jquery.com/jquery-latest.js we see the following: var jQuery = function( selector, context ) { // The jQuery object is actually just the init constructor 'enhanced' return new jQuery.fn.init( selector, context ); } My understanding of the new keyword in Javascript is essentially JavaScript passes the function an empty object {} and the function sets stuff on it via this.blah. Also from my understanding new differs from .call/.apply etc.. in that the return object also has the prototype set to that of the function. So the return value should have a prototype that the same as jQuery.prototype.init.prototype (or jQuery.fn.init.prototype). However from what I see its prototype is set to jQuery.prototype thus all the commands available to work on the set. Why is this? What am I missing in my understanding?

  • Minimize VirtualBox Hard Drive disk

    - by Aviv
    I have Ubuntu Server 10.04 TLS installed on a Virtual Machine in a VirtualBox. The size of the Hard Drive is dynamic growing hard drive and the maximum is 32GB. At the beginning i had 4GB on the Hard Drive and the size of the .vdi was 4GB. Lately the size of data on the disk is 15GB but the size of the .vdi is almost 32GB. Why is that? How can i pack / optimize / defrag the HD so it will be the same size of the data on the disk? Thanks.

  • Reverse Proxy (mod_rewrite) and Rails (absolute paths)

    - by SooDesuNe
    I have front end rails app, that reverse proxies to any of a number of backend rails apps depending on URL, for example http://www.my_host.com/app_one reverse proxies to http://www.remote_host_running_app_one.com such that a URL like http://www.my_host.com/app_one/users will display the contents of http://www.remote_host_running_app_one.com/users I have a large, and ever expanding number of backends, so they can not be explicitly listed anywhere other than a database. This is no problem for mod_rewrite using a prg:/ rewrite map reverse proxy. The question is, the urls returned by rails helpers have the form /controller/action making them absolute to the root. This is a problem for the page served by mod_rewrite because links on the proxied page appear as absolute to the domain. i.e.: http://www.my_host.com/app_one/controller/action has links that end up looking like /controller/action/ when they need to look like /app_one/controller/action mod_proxy_html seems like the right idea, but it doesn't seem to be as dynamic as I would need, since the rules need to be hard coded into the config files. Is there a way to fix this server-side, so that the links will be routed correctly?

  • automated printouts from a wireless printer

    - by Piotr
    I have a wireless printer which is always on, and an always on fanless linux server. Looking at the mprinter project on Kickstarter I started to wonder if there is an app somewhere in the internet already that will allow to prepare an automated daily printout based on some settings. things to be printed could include - weather forecast for my locations, todo`s scheduled for that day, a "quote of a day" or "word of the day", stats from google analytics for my site, and many more ... I would set a printout at 6:15 every work day so its on my printer when I am already up, having a coffee. anyone knows something that can be used for such purpose? While I know this can be done by combining the power of TeX, cron and a script language to manage the dynamic part of the PDF I believe this is a use case someone has already addressed.

  • How to change hybrid disk to basic disk in windows 7?

    - by Marco
    I created a partition E and then deleted the partition. After that I extended my partition C (where OS was installed) to take the space. My partition C became hybrid drive. My hp notebook does not have DVD rom and the notebook only came with an recovery image (I also have a paragon disc image). My computer has some problems now and I want to recover it by either the factory format or the paragon disc image. However, none of them works. I know it is because my disc has become hybrid disk. My question is how to fix the dynamic disk problem?

  • Is there a way to automate testing for a GNS3 network topology?

    - by Chedy2149
    I'm working on an MPLS backbone topology using GNS3, this topology includes configuration of several networking technologies such as IPv6, BGP, OSPF, IPv6 to IPv4 dynamic tunneling, MPLS based VPNs, MPLS based traffic engineering... So I'm a beginner with basic knowledge in networking (Ipv4 addressing, basic routing and switching) and I can't just easly test if my topology works or not, moreover fiddling with configuration I've noticed that sometimes when getting MPLS config right and missing BGP config all my topology is messed up. Given that I use Cisco 7200 series routers, is there any way to build a test harness for my topology in order to guarentee correctness with a single push button automated process?

  • How to make a server check it's own availability on the web?

    - by Javawag
    Hi all, Just a quick question – my server is running at my house serving www pages at www.javawag.com. The problem is that my home internet connection keeps dropping randomly - for about 10 mins at a time. This is only an intermittent problem and will go away soon I hope. However, my server doesn't recover properly - when the connection comes back, I can still access it at 192.168.0.8 (locally) without any issue, but at www.javawag.com there's no reply! (Just an aside - my home internet connection is dynamic ISP, the domain www.javawag.com points to javawag.dyndns.org which in turn points to my IP, updated every minute by ddclient on the server) Is there some way for the server to check if it's accessible from the outside world periodically, and if not restart Apache/reboot? Oh, and if I reboot the problem fixes itself also! Javawag

  • Iterator blocks and inheritance.

    - by Dave Van den Eynde
    Given a base class with the following interface: public class Base { public virtual IEnumerable<string> GetListOfStuff() { yield return "First"; yield return "Second"; yield return "Third"; } } I want to make a derived class that overrides the method, and adds its own stuff, like so: public class Derived : Base { public override IEnumerable<string> GetListOfStuff() { foreach (string s in base.GetListOfStuff()) { yield return s; } yield return "Fourth"; yield return "Fifth"; } } However, I'm greeted with a warning that "access to a member through a base keyword from an iterator cannot be verified". What's the accepted solution to this problem then?

  • How do I turn off caching in IIS7?

    - by jammus
    Hello. I'm developing an ASP classic site under Windows 7 (form a queue ladies). The problem is IIS seems to be heavily making use of its cache for both static and dynamic content which really conflicts with my 'make a small change, alt-tab, hit ctrl-F5' development style. Changes made to .asp files may take two or three refreshes to show up where as changes to .js files can take 20 times as many. How do I go about turning the caching off on my development machine? Cheers. in b4 stop using asp classic

  • Do I need to recompile PHP to make use of CURL API?

    - by amn
    I have both Apache and PHP set up manually, albeit the latter without CURL. There is this jungle of instructions and explanations on extensions for PHP. I have a very straightforward question - what do I need to do to enable CURL in a more dynamic way. I resent the idea of static linking, in fact I hate and avoid static linking like the plague. Is it possible to have my Apache and PHP understand that there is CURL in town? I can compile CURL if necessary. Package management may be out of the question, because I built PHP myself - I am on Ubuntu, and it does not provide PHP without Suhosin and a a whole lot of time, so I removed it and built PHP myself. The whole slew of related questions simply propse installing "php5-curl" package, which is exactly one thing I CANNOT do since it installs it in a completely unrelated directory, which my PHP does not even seem to bother linking to.

  • Making a relevant search of text in database using regex

    - by madphp
    Can anyone tell me how I could count the possible instances of a keyword in a block of text? I've split a search term up into separate tokens, so just need to run through and do a count for every instance and removing punctuation or other special characters when making the count. Secondly, if someone has inserted search terms surrounded by double quotes, i want to be able to skip explode, but just count instances of that exact phrase. It doesn't have to be case sensitive and I would like to remove punctuation from the phrase when doing the count. Thirdly, in both cases i want to be able to ignore wordpress and html tags. Lastly, if anyone know any good tutorials for relevant searches that answer the questions above, that would cool too. I've got this far. $results = $wpdb->get_results($sql); $tokens = explode('search_terms'); // Re-arrange Relevant Results foreach ($results As $forum_topic){ foreach($tokens As $token){ // count tokens in topic_title if ($token ){ } } }

  • Best way to use mod_rewrite to replace WordPress pages with static files

    - by David Moles
    Here's the situation: I've got an old WordPress installation that I'd like to archive as static files, but I'd also like to preserve old URLs. I've already created the static archive with wget and sorted out the filenames and links. Now I'd like to configure Apache to intercept requests for the old dynamic URL and replace them with the new static one, e.g.: http://www.example.org/log/?p=1234 or http://www.example.org/log/index.php?p=1234 should redirect to http://www.example.org/log/archives/1234.html I've tried adding the following to the VirtualHost config for example.org, but to no effect -- I just get the PHP page. RewriteCond %{REQUEST_URI} /log/ RewriteCond %{QUERY_STRING} p=([^&;]*) RewriteRule ^/$ http://%{SERVER_NAME}/log/archives/%1.html [R,L] I've enabled logging and I can see what look like other rules being applied, but not this one. None of my other guesses at match patterns for %{REQUEST_URI} seem to have any effect either (log, log/, log.*, even .*). I'm new to mod_rewrite and this is mostly cargo cult, so I'm pretty sure I've gotten it wrong. Anyone know what I should be doing here?

  • SQL query: how to translate IN() into a JOIN?

    - by tangens
    I have a lot of SQL queries like this: SELECT o.Id, o.attrib1, o.attrib2 FROM table1 o WHERE o.Id IN ( SELECT DISTINCT Id FROM table1, table2, table3 WHERE ... ) These queries have to run on different database engines (MySql, Oracle, DB2, MS-Sql, Hypersonic), so I can only use common SQL syntax. Here I read, that with MySql the IN statement isn't optimized and it's really slow, so I want to switch this into a JOIN. I tried: SELECT o.Id, o.attrib1, o.attrib2 FROM table1 o, table2, table3 WHERE ... But this does not take into account the DISTINCT keyword. Question: How do I get rid of the duplicate rows using the JOIN approach?

  • Word 2007 "Out of Memory or Disk Space" Error on launch

    - by Adam
    Word 2007 is installed on a Vista Home Premium machine and whenever it starts up it opens what appears to be a dynamic installer to do something and then throws up the "Out of Memory or Disk Space" error. Word 2007 never completes starting up. Reinstalling Word hasn't helped and if I can avoid reinstalling Windows until Windows 7 is released and get Word working in the mean time, that would be ideal. I've been looking around for a solution, once of which seemed to point to a problem with the user account. I created a second user on the machine and Word still had the same problem. The other solution that seems possible is a corrupted normal.dot/normal.dotm file. However, even in the location it should be, I can't seem to find it. Am I going in the right direction with this? Is there another solution I haven't come across that will fix this? If it is possible that renaming normal.dot/normal.dotm how can I find it?

  • Can Ping but Cannot Telnet directly to SQL Server 2012 Cluster Nodes

    - by tresstylez
    We have a monitoring tool (Solarwinds Orion) that needs to connect to a 2-node failover SQL Server Cluster. For reasons outside of our control -- we cannot monitor the CLUSTER IP directly at this time, so we have fallen back to monitoring each cluster node IP directly. This is not working. Upon troubleshooting, we tried to test that the cluster node was listening on the proper (fixed) port by using telnet to the cluster node IP/port -- and the telnet failed. However, telnet'ing to the Cluster IP/Port was SUCCESSFUL! Each node has its own IP. Each node is listening on the identical FIXED port. Each node has Dynamic Ports disabled. Each node can be PINGED successfully from the monitoring tool. Windows Firewall is DISABLED. How can I troubleshoot why I cannot telnet to the listening port on the cluster nodes?

  • Tracking my home IP from anywhere on the internet?

    - by oKtosiTe
    I have an ISP that serves semi-permanent IPv4 addresses. They can't promise fixed IP addresses, but unexpected changes are quite rare. This begs me to ask however: what would be the easiest/most reliable way to track my home IP address so I can access my (Windows 7) home server even in the case of an address change? Please note: for reasons that I don't want to go in to, I'd like to avoid using any "dynamic DNS" type services. Instead I'd prefer some way to perhaps have the home server leave an occasional/triggered "address stamp" on a remote, off-site server (by SSH, HTTP post or similar, preferably over an encrypted connection).

  • Fast exchange of data between unmanaged code and managed code

    - by vizcaynot
    Hello: Without using p/invoke, from a C++/CLI I have succeeded in integrating various methods of a DLL library from a third party built in C. One of these methods retrieves information from a database and stores it in different structures. The C++/CLI program I wrote reads those structures and stores them in a List<, which is then returned to the corresponding reading and use of an application programmed completely in C#. I understand that the double handling of data (first, filling in several structures and then, filling all of these structures into a list<) may generate an unnecessary overload, at which point I wish C++/CLI had the keyword "yield". Depending on the above scenario, do you have recommendations to avoid or reduce this overload? Thanks.

  • How to reference individual cells in Excel to variable data from records in an external SQL table

    - by user273476
    I have a SQL table containing date oriented financial data eg. multiple daily records with fields for Date, Account code and Value. I want to set up dynamic links (formulas) from cells in an Excel speadsheet to this data so when the spreadsheet is loaded the data is fetched from all the relevant records. The spreadsheet has the Account codes on the x axis and Dates on the y. Each day the SQL table has new data in it for the new day and I want the spreadsheet to reference this new data for the column for the new day. Any ideas? I have seen how you can generally bring in data from a SQL table (in our case using ODBC as it is not MS SQL) but the data is not simply bringing in multiple records as you would a CVS file but specific records in the SQL table referencing to specific cells and columns in the spreadsheet.

  • Ruby/RoR: calling original method via super()?

    - by fearless_fool
    In a RoR app, I want to specialize ActiveRecord's update_attributes() method in one of my models, extracting some of the attributes for special handling and passing the rest of them to the original update_attributes() method. The details: class Premise < ActiveRecord::Base ... def update_attributes(attrs) attrs.each_pair do |key, val| unless has_attribute?(key) do_special_processing(key, val) attrs.delete(key) end end # use original update_attributes() to process non-special pairs super.update_attributes(attrs) end ... end The call to super.update_attributes(attr) raises an error: undefined method `update_attributes' for true:TrueClass ... which makes me suspect I really don't understand the super keyword in Ruby. What am I missing? Specifically, how do I call the original update_attributes() method?

  • Sharepoint 2010 reacts very badly to having it's IP address changed. How do I fix it?

    - by Jeff Sacksteder
    I have Sharepoint 2010 set up on a virtual host for prototyping various projects. If I restart the host, the IP changes. Afterwards, SP complains that it can't find it's configuration database. I can't find where it might be storing an IP. To clarify, the URL remains the same - I have a dynamic dns solution in place to handle that. I can't see anything in the web.config files or the database connection strings that would indicate a hardcoded IP. How can I fix this up in less time than re-installing every time I need to do a project?

  • C# Inherited member variables behaving undexpectedly

    - by Nilbert
    If I have a class like this: class A { public string fe = "A"; } And a class that inherits from it like so: class B : A { public string fe = "B"; } Visual C++ will tell me that B.fe hides A.fe so I should use the new keyword. So I change class B to look like: class B : A { public new string fe = "B"; } And then I have a function that takes an A (but, by virtue of inheritance, will also take a B) like this: class D { public static void blah(A anAObject) { Console.Writeline(A.fe); } } Even when I pass it an instance of a B object, which it will take without question, it will print "A"! Why is this, and how can I make it work how I want without setting the variable in the constructor?

  • Have Free website Hosting with Google App Engine

    - by mickthompson
    I'm reading about Google App Engine. I'm creating a bunch of simple dynamic websites in java. I'm considering to use Google App Engine and setup my clients' website on it. In this way I've only to register a domain www.myclietdomain.com and then point that to the GoogleAppEngine application... In this way I plan to avoid hosting costs. Infact I'm paying even for hosting few static html pages... Do you think that is possible to use Google App Engine for this scope?

  • Twitter Search API Question

    - by supermogx
    I'm using the twitter search API to get twitter posts based on some keywords, using AND and OR keyword. It works OK, but I seem to get problems using hashtags... For example : Not returning any results : http://search.twitter.com/search.json?q="%23ipad+AND+%23ipod"+OR+"%23joke+AND+%23funny"&rpp=100&callback=? Returning results : http://search.twitter.com/search.json?q="ipad+AND+ipod"+OR+"joke+AND+funny"&rpp=100&callback=? But there's results with #ipod AND #ipad because when I search only for #ipod, I can see a lot of posts with both hashtags. Example : http://search.twitter.com/search.json?q=%23ipad&rpp=100&callback=? P.S. %23 = # Any idea?
