• Motherboard or Processor Problem

  - by bradlis7

  My computer is broken, but I'm having trouble narrowing down the issue. I replaced the power supply, because I assumed that was the issue, but it has the same problem. The issue started with my computer starting the fans and running, but it didn't get to the BIOS screen for about 10 seconds. Now it refuses to do anything when the power button is pressed, except when I turn off the machine and take the processor out for 10-20 seconds, then put it back in, I came hit the power button immediately, and the fans start for 1/2 second, and quit. Does this sound like a is a processor or motherboard issue? I removed all components, so I know that the issue is with one of these two things.

• Get other classes from an element with Jquery

  - by Jigs

  I am working on a small bit of script that will allow for easy and flexible creation of buttons. My buttons are made of three parts, a left, a right and a streched middle piece. There are three different sizes and three different colours of each. I have written the code that resizes the button to fit the text. Now I am looking to add the ability to easily set the colour and size. I was thinking of using three classes something like <div class="button blue big"> My script already loops through the button classes using each. Now I need to find out what other classes are set and adjust the pictures and dimentions used to fit. So how can I find out what other class selectors an element has? Also I am fairly new to jquery/javascript so I am wondering if storing the design as class selectors is the best way.

• Redirect audio from laptop to desktop over LAN

  - by Ram Rachum

  I want to be able to play a song on my laptop and have it sound through my desktop's (infinitely better) speakers. If you're familiar with Input Director: I want something that is to audio what Input Director is to mouse/keyboard. I want something that automatically redirects all audio from the laptop to the desktop in real time, and I want that solution to require, like Input Director, minimum maintenance. Beyond the initial setup, I don't want to have to babysit the program that does this. I want something that launches automatically with Windows and just works, and also allows me to cancel it whenever I want. And also doesn't go crazy when the laptop is turned on in a different network where the desktop computer isn't available. Any suggestions for such a program? (I use Windows XP on both computers.)

• Adding an additional link button to a form (using form->create)

  - by cloudhead

  I have recently been assigned a CSS & design project that's in a CakePHP environment and would like to know if I can add an additional button to the form, for a "sign up" link. The form is currently: echo $form->create('User', array('action' => 'login')); echo $form->inputs(array( 'legend' => 'Please log in:', 'username', 'password')); echo $form->end('Login'); I would like to inject a button that goes to an action of 'register', preferably after the "Login" button, on the same line, like this: username: [ ] password: [ ] [Log In] [Register] I have everything but the 'register' button. Is this possible using the 'automagic' form creation? Thank you.

• Controlling a browser from Python

  - by Noio

  I am looking for a way to control a browser from Python, i.e. fill out form fields and submit them, possibly call JS functions. I've looked around a bit, but as far as I could see PyWebKitGtk only lets you show the browser as a GUI element, not interface with it. Is there a way to do this easily? I wrote my program logic in Python, and I would hate to port it to JS. Besides that, even if I'd use pure JS "bookmarklets", those wouldn't be able to read/write to my local filesystem, would they? P.S. to quell your suspicions, I'm not trying to automatically fill out forum account creation forms or something similarly spammious, though the task is technically similar. I need to crawl/scrape sites for my research project.

• Reading PDF metadata in PHP

  - by Mark Trapp

  I'm trying to read metadata attached to arbitrary PDFs: title, author, subject, and keywords. Is there a PHP library, preferably open-source, that can read PDF metadata? If so, or if there isn't, how would one use the library (or lack thereof) to extract the metadata? To be clear, I'm not interested in creating or modifying PDFs or their metadata, and I don't care about the PDF bodies. I've looked at a number of libraries, including FPDF (which everyone seems to recommend), but it appears only to be for PDF creation, not metadata extraction.

• Dual Monitors don't turn off/sleep when they should

  - by Mario

  Details: Dual 25" monitors connected to HP Envy via HDMI and display port via DVI adapter. Power scheme is set up in high performance (Dim Display: Never - Turn Off Display: 15 mins - Computer Sleep: Never) Screensaver is set up to kick in after 10 mins of idle (which happens) 5 minutes later, the screensaver stops. The "Monitor Going to Sleep" notice appears on screen and monitors go to sleep briefly. All is well thus far. Suddenly, the Windows 7 alert sound when a device is unplugged is heard. Monitors then turn back on. Screens are black. Only the mouse cursor is displayed. Backlighting is back on. This only started happening after I obtained and connected the second 25" monitor a few days ago. However, I had a 24" in its place before, and this wasn't happening. Why is this happening and how do I correct this behavior? Thanks in advance.

• Creating a webserver from scratch

  - by Val

  I know this is going to sound a humongous task and many of you would think why in the world would you want to do so or why re-invent the wheel. However I just want a project I can work on the side see how it goes and experiment ( I got a thirst for learning something new and this is a great challenge). Question Where would I start creating a server-side scripting like php, asp and (now) node.js I would like to have a few examples, and most importantly a CODEX/documentation where I can learn and find out more how it works. I guess I am asking for directions where to go to read and find out more about this. Many thanks,

• Monitor sometimes display weird colors and lines when opening a website that contains a video

  - by WEEYE

  This happens 1/50 times when I open a website that contains a video. I don't know if it happens when I open a flash video, but I am sure it has happened when I've opened a HTML5 video. When it happens I have about 2-3 seconds to press Alt + F4 (to close my browser). If I do it in time the screen will get back to normal. If I wait too long to press Alt + F4, maybe 3+ seconds, my screen won't get back to normal when I press Alt + F4. However, when I get stuck in the weird screen I can do all types of things on the computer. the whole computer does not freeze, because if I for example press Win + L I will hear the Windows logout sound. I have HD7870, Windows 7. http://tinypic.com/r/3519tf9/5

• Does MySQL allow two primary keys on one table?

  - by Bharanikumar

  CREATE TABLE Orders -> ( -> ID SMALLINT UNSIGNED NOT NULL, -> ModelID SMALLINT UNSIGNED NOT NULL, -> Descrip VARCHAR(40), -> PRIMARY KEY (ID, ModelID) -> ); Basically, this appears to me to be creating two primary key on one table. Is that correct? I thought that we could create a number of unique keys in one table, but only one primary key. How is it that my system is allowing the creation of multiple primary keys? Please advise: what are the rules governing this?

• Computer stopped working (ASUS P5GD1-VM)

  - by Gordonrjones

  My computer stopped working the other day. I came down and it was kind of chirping away. Then, when I restarted it, it only did the same thing. I unplugged everything not needed and it did nothing at all. I thought maybe the power supply wasn't working, but when I took the cover off the green light on the motherboard was on and the power supply is making a little buzzing sound. But nothing happens when I turn the computer on, other than the green light on the motherboard flickers a bit. I checked the memory in other computer and it works fine. I'd love to be able to fix this with as little cost as possible. Can someone here help? P4-640 (3.2E GHz, 800 FSB, L2:2MB, EM64T, HT)

• bursty streaming video

  - by broiyan

  What is the cause and solution for the bursty streaming media problem? Example: when streaming from youtube, audio (and video) will pause and start intermittently. When it starts it will be bursty, that is, it will play several seconds of sound in just a fraction of a second. Normal sounds are rendered unrecognizable. Then it may pause and after a few seconds, resume with another burst. The video seems to burst along with the audio. This was observed on Ubuntu 12.04 with Google Chrome.

• Managing multiple blogs (wordpress) from one control panel

  - by thisMayhem

  This is the deal: I have more than one blog (not running yet) that I want to install in subfolders for one of my domains. Each blog will obviously have its own look and feel and content. I could just have a set of control panels and administer them individually or I could somehow manage them form a single control panel. Issues I've come across are: Some plugins offer this functionality while suppressing other features like auto draf saving, in-post category and tag creation, image upload etc. I'm not necessarily looking for a ready solution, more like some guidance on how to approach this particular problem in the best possible manner. I'm looking for a fully working scenario, not some plugin that allows me to more or less simulate the one-blog-administration experience.

• odd behavior setting timeouts inside a function with global references in javascript

  - by Pablo

  Here is the the function and the globals: $note_instance = Array(); $note_count = 0; function create(text){ count = $note_count++; time = 5000; $note_instance[count] = $notifications.notify("create", text); setTimeout(function(){ $note_instance[count].close() }, time); } The function simply opens a notification, a sets a timeout to close it in 5 seconds. so if i call this create("Good Note 1"); create("Good Note 2"); create("Good Note 3"); Ecah note should close 5 seconds from their creation, however always and only the last note closes, in this case "Good Note 3". Each note object has its own entry in the the $note_instance global array so the timeouts should no be overwriting themselves. What am i missing here folks? Thanks in advance

• Database normalization and duplicate values

  - by bretddog

  Consider a Parent / Child / GrandChild structure in a database table schema, or even a deeper hierarchy. These being in the same aggregate. One table DAYS keeps a single row per day, and has a "Date" field. This is the root table, or maybe a child of the root. No row can ever be deleted in this table. In this case, however complex my table schema looks like, however far away in the hierarchy any other table is, is there any reason why any other table would hold a Date value? Can't it instead just have a FK to the DAYS table. I obviously assume that the creation of these date fields happen not before such datefield exist in the DAYS table. I'm now thinking just about the date part to be relevant, not the time part. Not sure if all databases can store these individually. That's maybe relevant, but not really the focus of the question.

• RoR model field without validators, has*, delegates, etc

  - by jackr

  How can I declare a field, in the Rails model, when it doesn't have any "has_" relations, or validations, or delegations? I just need to ensure its existence and column width in the schema. Currently, I have no mention of the field in the "schema section" of the model file, but it's referenced in various methods that use it, and this seems to work. However, depending on my exact creation workflow, the underlying database table may be created as t.binary "field_name", :limit => 32 or t.binary "field_name", :limit => 255 This is not a restriction on the value (any binary value is valid, even NULL), only on the table column declaration. As it happens, 32 is enough -- it never receives any larger value, it's only ever written to like this: self.field_name = SecureRandom.random_bytes(32)

• USB Mouse doesn't work after turning on Laptop

  - by Barry

  I have a USB mouse attached to my laptop which does not work when I switch my laptop on. I have to unplug it and plug it back in before it works. When I do this no driver installation occurs (presumably because it has already done this) the usual beep sound does occur and the mouse starts working again. If my laptop goes to sleep I can move the mouse and the laptop comes back to life. In fact it works perfectly apart from this annoying niggle on startup. Can anyone shed any light as to why I have to keep unplugging and plugging my mouse back on startup? I am running Windows 7 Home Premium Service Pack 1 (64 bit) on a Toshiba Satellite L755-1LL Laptop.

• How to Reset Windows 7 to its default font for the whole system?

  - by Fellknight

  This might sound a little bit silly but please bear with me. Somehow I changed my default display font, the one that Windows uses for system dialog boxes, accept/cancel buttons, pretty much everything in the system (it even goes as far as to change how my the text in my web browser appears). Now everything that it's affected looks like under the effects of the bold button in office (very black and very thick words). This is an inconvenience for example on some mail accounts who use this effect to display unread messages. Is there any way to return it to its default state, non "bold" typography for the whole system?

• NVidia raid 5 array spooling sounds and delay

  - by Chase B. Gale

  I've had a raid 5 array setup with 3 2TB WD Green drives for about 3 years now. Starting last week, when I would access the array for the first time, I hear a loud drive spooling sound and experience a ~5 second delay before being able to access\save files. This behavior happens when I don't use the array for some time (about an hour) and after occurring it doesn't happen again if I continue to access the array. I've run SMART scans on all drives and they come back as being a-ok. What's causing this? Is my array getting close to death?

• problem with TEMPORARY TABLE

  - by Z77

  Within PHP I do: 1.) A temporary table is created: CREATE TEMP TABLE new_table AS SELECT .... FROM ...; 2.) AFter that I want to use this table to create a shape file: shell_exec ("pgsql2shp .... -u username -P password ...); Separetly those two things work, but by creating a temporary table and after that using this table in pgsql2shp does not work. I pressume this is because temporary table duration is to the end of session. But to create shp file I need to use username and password what means new session starts and temporary table is dropped before I use it for shape creation. Any tip how to solve it? Thank you!

• A lot to merge after creating a new branch in SVN

  - by homaxto

  We have recently made a new branch, let us call it rel3.6, which was based on the last release named rel3.5. Work has started on rel3.6, and meanwhile some bugs has been fixed on rel3.5 which now is used for a service pack to be released soon. Today I wanted to merge those bugs from rel3.5 to rel3.6, so I fired up SmartSVN. Standing in the rel3.6 branch i chosed\ to merge with rel3.5 and selected to browse for a revision range. To my surprise there was a huge list of changes even though I checked "Stop on copy" and only showing mergeable revisions. Most of them where dated back before the creation of rel3.6. I did not expect to find anything from before rel3.5 was created. If I make a merge, the only thing I get are changes and conflicts to directory properties. Have I misunderstood something, or is it possible that something was done wrong when creating the branch?
