• How can I check that I'm not frying the chipset on my 945 gclf?

  - by Journeyman Geek

  I'm running an old 945 gclf as a home server. Its an odd little system which has a passively cooled single core atom 230 processor, and a small heatsink/fan combo over the chipset. lm-sensors/sensors detects one temperature sensor which I guess is the processor. coretemp-isa-0000 Adapter: ISA adapter Core 0: +38.0°C (crit = +100.0°C) The fan on it is making rather horrible noises and I am considering unplugging it or using a speed reducer. There's also a risk it may fail anyway. Is there any way I can monitor the temperatures of the chipset or be warned of any issues with it? Is there anything specific I can watch out for that would indicate trouble?

• Will Haskell be a good choice for my task?

  - by Narzanka

  I'm starting a new project and don't know which language to use. My 'must have' requirements are: Be able to run on Windows/LinuxMacOs natively (native executable) - user should be able to just run the exe (when on Windows for example) and see the results. No runtimes/interpreters (no jvm, clr, etc) - one file download should be enough to run the application. Full unicode support. Be able to manipulate OS threads (create them, run multiple tasks in parallel on multi-core CPUs, etc). Be reasonably fast (Python level performance and better). To have some kind of standard library that does low-level, mundane tasks. Not very niche and have some community behind it to be able to ask questions. My 'nice to have' requirements are: Language should be functional It should have good string manipulation capabilities (not necessarily regex) Not extremely hard to learn I'm thinking about Haskell now but keeping in mind OCaml as well. Please advice if my choice is correct.

• How to know if the website being scraped has changed?

  - by Lost_in_code

  I'm using PHP to scrape a website and collect some data. It's all done without using regex. I'm using php's explode() method to find particular HTML tags instead. It is possible that if the structure of the website changes (CSS, HTML), then wrong data may be collected by the scraper. So the question is - how do I know if the HTML structure has changed? How to identify this before storing any data to my database to avoid wrong data being stored.

• Wordpress & Vanity User URLs

  - by st4ck0v3rfl0w

  Hi All, Was wondering if anyone had any smart approaches to creating dynamic vanity user urls upon user registration. My site basically uses emails as usernames. I have the regex to strip the text before the "@" symbol (e.g. "[email protected]" becomes "name") I would then like to take the "name" and create a vanity url (e.g. domain.com/name or name.domain.com) Any thoughts on how to accomplish this with Wordpress? I'm a pretty advanced Wordpress user and my first thoughts were to do the following Verify user registration Upon successful user registration create page name with username as the title (this would help me achieve the www.domain.com/username) Apply preset template to that page with the desired view Any and all thoughts are welcome.

• Problematic tags displaying HTML in Java

  - by Andez

  Hi again, I have the following tag included in my HTML which causes the JEditorPane not to show the HTML output. <META http-equiv="Content-Type" content="text/html; charset=UTF-8"> Not so much a big deal but anyone know why this would happen? Cannot find too much documentation on this - best I came up with was someone having a go a few years ago to see what was supported on retro virus site. At the minute I'm doing a simple find replace on the string which is not good - are there any better ways? I've seen a lot of people saying that RegEx is no good. The code I have used is this._html = this._html.replace( "<META http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\">", ""); Andez

• Long term system health monitor

  - by user30336

  As an experienced user, I sometimes notice that things are not going well with my computer. For example, my backup drive recently started cycling up and down, so I guessed it was probably dying, and replaced it. I detected this with my ears. Windows did not seem to notice or care. There ought to be software that monitors overall system health by keeping track of things like this, so that unusual events or increasing error rates will not be shrugged off. Among other things: disk errors that are recovered, corrupt network packets (at above the baseline expected rate) and crashes of trusted programs are early warnings. Is there any software that tries to use this kind of monitoring to warn of impending trouble?

• Writing directory: permission denied even though dir seems to be chmodded correctly

  - by Aron Rotteveel

  I am having some trouble creating files in directory on my Ubuntu machine: I added myself to the www-data group in order for me to easily edit stuff in my /var/www dir on my development machine. stat /var/www shows the following: File: ‘/var/www’ Size: 4096 Blocks: 8 IO Block: 4096 map Device: 808h/2056d Inode: 142853 Links: 3 Access: (0775/drwxrwxr-x) Uid: ( 33/www-data) Gid: ( 33/www-data) Access: 2010-12-30 16:03:18.563998000 +0100 Modify: 2010-12-30 16:02:52.663998000 +0100 Change: 2010-12-30 16:03:13.111998001 +0100 Still, it is impossible for me to create anything below /var/www (the only way for it to work is to chmod it to 777. What am I missing?

• how to use replace_regex_copy() from boost::algorithm library?

  - by Vincenzo

  This is my code: #include <string> #include <boost/algorithm/string/regex.hpp> string f(const string& s) { using namespace boost::algorithm; return replace_regex_copy(s, "\\w", "?"); } This is what compiler says: no matching function for call to ‘replace_regex_copy(const std::basic_string<char, std::char_traits<char>, std::allocator<char> >&, std::string, std::string) The link to the library: http://www.boost.org/doc/libs/1_43_0/doc/html/boost/algorithm/replace_regex_copy.html Could anyone please help? Thanks! ps. Boost library is in place, since other functions from it work fine.

• Converted VmWare Image does not boot in Virtual Box

  - by vBox Question

  I have a .vddx virtual image which boots in VmWare, but I'm having trouble getting it to work with Sun Virtual Box. In Sun Virtual Box, I created a new Virtual Machine and pointed it at the vddx file from VmWare. When I try to boot the virtual machine, Sun Virtual Box says that the volume is not bootable. VmWare is able to boot from this virtual machine. Does anyone have any suggestions about what might be causing the problem? Is there a conversion utility that I need to run? Any debugging options that I could turn on?

• Are there design-time watch windows for Visual Studio 2008/2010?

  - by Jeff

  There are many times when I need to test a little snippet of .net code but rebuilding and publishing the entire project or writing a suite of unit tests just seems like overkill. For example, I am writing a regular expression right now and I want to see if it the pattern is matching on the right parts. I could go and find a million other utilities that do that sort of thing, but that is not exactly my point. FireBug has an exact analogue to what I want - the FireBug console. There is a text box where the user can enter some JavaScript and FireBug will execute it on the spot and display the return value. I would love to be able to enter something like (new Regex("b+")).Replace("abc", "x") and see the results without having to do all the overhead. Does VS have anything like this?

• Tag suggestion (not tag autocomplete)

  - by takeshin

  AJAX autocomplete is fairly simple to implement. However, I wonder how to handle smart tag suggestion like this on SO. To clarify the difference between autocomplete and suggestion: autocomplete: foo [foobar, foobaz] suggestion: foo [barfoo, foobar, foobaz], or even better, with 'did you mean' feature: [barfoo, foobar, foobaz, fobar, fobaz] I suppose I need some full text search in tags (all letters indexed, not just words). There would be no problem to do it witch regex or other patterns for limited number of tags (even client side). But how to implement this feature for big number of tags? Is there any particular reason (besides URL) the tags on SO are dash separated? What about Unicode characters in tags? I store the tags in the table with the following columns: id, tagname. My SQL query returns objects with following fields: id, tagname, count

• Server Design Enquiry [closed]

  - by Brandon Gelfand

  I am really new to this and am having trouble with how I can store information from a website. I am going to be making a site similar to dropbox for my company and there is gonna be around 40 TB of space that we need to be able to access on the go, for instance pull the file up on the phone or off our laptop using the internet. Obviously using an Amazon S3 server is not the most cost effective way of doing this so how can I make my own server to hold all of the info and communicate to it from a website? Please I need as much help as possible, like a blueprint or something. Thanks and sorry for the noobish question but I can't really find an exact answer to my question.

• Apache server, PHP

  I am running a php site on my apache server (Mac). I am having trouble displaying images on the site when I access it externally or from another computer on the same server. If I try to access the image directly. website.com/image.jpg I get a broken link icon and can't display the image. Any ideas what could cause this? My images are embedded using a style.css file. background-image:url(image.jpg);

• Prevent "jQuery( html )" from triggering the browser to request images and other referenced content

  - by Chris Dutrow

  Using jQuery to create new DOM elements from text. Example: jQuery('<div><img src="/some_image.gif"></img></div>'); When this statement is executed, it causes the browser to request the file 'some_img.gif' from the server. Is there a way to execute this statement so that the resulting jQuery object can be used from DOM traversal, but not actually cause the browser to hit the server with requests for images and other referenced content? Example: var jquery_elememnts = jQuery('<div><img class="a_class" src="/some_image.gif"></img></div>'); var img_class = jquery_elememnts.find('img').attr('class'); The only idea I have now is to use regex to remove all of the 'src' tags from image elements and other things that will trigger the browser requests before using jQuery to evaluate the HTML. How can jQuery be used to evaluate HTML without triggering the browser to make requests to the server for referenced content inside the evaluated HTML? Thanks!

• Concatenation awk outputs

  - by Rookie_22

  I'm using regex to parse NMAP output. I want the ip addresses which are up with the corresponding ports open. Now I've a very naive method of doing that: awk '/^Scanning .....................ports]/ {print substr ($2,1,15);}' results.txt awk '/^[0-9][0-9]/ {print substr($1,1,4);}' results.txt | awk -f awkcode.awk where awkcode.awk contains the code to extract numbers out of the substring. The first line prints all the ips that are up and 2nd gives me the ports. My problem is that I want them mapped to each other. Is there any way to do that? Even sed script would do.

• cron library for java

  - by nutsiepully

  I am looking for a cron expression library in java. Something that can parse cron expressions and return me future fire times for the trigger. API on the lines of. CronExpression cronExpression = new CronExpression("0 30 4 * * *"); List<Date> fireTimes = cronExpression.getFireTimes(todaysDate, nextWeekDate); I don't want to use something as complicated as quartz. The purpose is to basically use cron like a regex for timings. That's all. I do not want a background scheduler. I tried googling but wasn't able to find anything very helpful. Any suggestions would be appreciated. Regards, Pulkit P.S - I looked at using the CronExpression class out of quartz. Wasn't very helpful - failing some tests.

• Visual Website Optimizer and Code Igniter

  - by absentx

  We are trying to integrate visual website optimizer into a site of ours that uses Code Igniter. The problem is when we go into the VWO control panel to look at stats and previews nothing seems to be working. In the previews panel, all of them come up as code igniter error pages that say "The URI you submitted has disallowed characters." I have researched some solutions to this and have tried changing the regex in system/config to allow more characters, all characters etc and I am still having the problem. Any known issues or problems trying to integrate VWO and Code Igniter? This definitely seems to be a url issue but I can't nail it down.

• New 2.5" hard drive for laptop - What to compare?

  - by TFM

  I'm having trouble finding a new (bigger) hard drive for my laptop. I came across some criteria that I never thought about before, while I was checking a price comparison site. Of course, that made me more confused. First of all, I will probably go with something above 250 GB, and at least 16 MB cache. Now the confusing part: Most new drives are 7200 RPM, as opposed to good old 5400 RPM. 7200 RPM used to mean extra heat, but suddenly it's almost impossible to find a 5400 RPM in 2.5". What did I miss? Second question: Internal data transfer rate. My old drive has a rate of around 60 MB, but new drives have values like 100 MB or more (e.g. 150 MB). How important is this "internal data transfer rate"?

• How to remove [^a-z\s] in C++

  - by Steven

  So far I have: int SimplifyText(char chars[], int length) { //To lower for(int i=0; i<length; i++) { chars[i] = tolower(chars[i]); } This function simplifies the text in the first argument which is an array containing the number of characters as given in the second argument The requirements are: tolower all remove all non-alpha characters replace multiple whitespace by one blank. Any leading whitespace at the beginning of the array should be removed completely. The resulting number of characters should be returned as the value of the function. And the annoying part: Another array cannot appear in the function Cannot use strings, only char arrays. Cannot using G++'s extension for setting an array size using a variable. Oh and can't use regex :) I'm stuck with this, any help would be great. :)

• C# method contents validation

  - by user258651

  I need to validate the contents of a C# method. I do not care about syntax errors that do not affect the method's scope. I do care about characters that will invalidate parsing of the rest of the code. For example: method() { /* valid comment */ /* <-- bad for (i..) { } for (i..) { <-- bad } I need to validate/fix any non-paired characters. This includeds /* */, { }, and maybe others. How should I go about this? My first thought was Regex, but that clearly isn't going to get the job done.

• Why do some servers have so many processes running?

  - by Xeoncross

  I have two VPS servers but they have drastically different amounts of memory usage and processes running. I'm still new to running linux servers so I'm having trouble figuring out what is going on and what I can do to fix it. Both are Debian 5 32bit installs. On one server with 128MB of ram and a single CPU core I have a full server running in only 84MB of RAM. The other server has 512MB (quad core CPU) and it has nothing running but core processes yet its still using 94MB of RAM. Does one have a different kind of virtualization technology that requires more linux core processes or what?

• jQuery filter selector, is this right?

  - by fire

  It seems to work ok but I don't know if this can be impoved on or not. I want to select any HTML tag that has a class of edit-text-NUM or edit-html-NUM and change the color of it. Here is what I am using... jQuery(document).ready(function(){ jQuery('*') .filter(function() { return this.className.match(/edit-(text|html)-\d/); }) .css({ 'color': '#ff0000' }); }); Does that look ok and is the regex ok? *edit: Also is this efficient? I am aware that using jQuery('*') might be a bit of a hog if it's a large page. It only has to work from <body> down so maybe it could be changed?

• Read external HTML page and then find data within

  - by inthewayboy

  I'm playing around with an idea, and I'm stuck at this one part. I want to read an external HTML page and then extract the data held within two <dd> tags. I've been using file_get_contents with good results, but I'm at a loss as to how to accomplish that last part. The two tags I want to extract the value from are always enclosed within a particular <div>, was wondering if that might help? In my mind it reads the entire html file into a string, then dumps all the data up until this one particular <div>, and dumps all the data after the closing </div>. Is that possible? I think this needs regex syntax which I've never used yet. So any tips, links, or examples would be great! I can provide more info as necessary.
