• Firefox and Flash requires 2 clicks after Scrolling?

  - by Kerry

  I've noticed this with me and my partners computers, take a look at this: http://www.uploadify.com/demo/ Those buttons are flash. If you scroll (scroll to the bottom then back up, using your mouse scroll) then hover over a button, it is a normal pointer, not a hand. If you click on the button, then it turns into a hand, then you can click on it to trigger the browse files window. Is there any way to fix this? Is this a Firefox bug (doesn't happen in Chrome or IE8)?

• Why does the CPU usage reach 100% when laptop is plugged in?

  - by Mayank

  I have an HP Elitebook 8440p with Windows 7 Ultimate, i7 Processor and 8 GB RAM. For the last couple of days, when I plug-in my laptop for charging, the CPU usage shoots up to 100% and remains there for around 15 minutes. No offending process shows up in Task Manager/Process Explorer but the laptop is practically unusable for that time. The CPU usage becomes normal when I remove the power cord but shoots up again when plugged back. This is happening with different power adapters/wall sockets so it might not be a faulty adapter issue. Why is this happening and any pointer to resolve this issue?

• C++ and Scripting.Dictionary from scrrun.dll

  - by MaxFX

  Hello. I have some trouble with Scripting.Dictionary in C++. I'm trying to use interface IDictionary via smart pointer but methods of creating object don't work and I can't understand why. CoInitialize(NULL); IDictionaryPtr dict; dict.CreateInstance(__uuidof(Dictionary)); _variant_t num1 = 1; _variant_t num2 = 2; dict->Add(&num1, &num2); long i; dict->get_Count(&i); cout << i << "\n"; But method Add does not work and cout of elements in dictionary is always 0. How correct to use Scripting.Dictionary in that case. PS.: I'm getting Scripting interfaces by #import "scrrun.dll"

• Is it valid for RSS feeds to include images with relative paths?

  - by Brian Armstrong

  I have an app which reads lots of RSS feeds. Someone added a feed recently that includes images in the html portion with relative URLS (i.e. it didn't include the http://www.domain.com/ part in front). Is this valid html for an RSS feed? I thought not, but I tried adding the feed to my Google reader and it picked up the images correctly, so they must be doing something smart where they guess the domain based on the feed's url parameter or something. Even if it's not valid, how common is it to see feeds like this in the wild? To display it correctly would require you to parse the html in the feed and find/replace parts of it to insert full URL's, so this seems wrong. But wanted to double check.

• Java preferences API throughput

  - by Domchi

  I'm using Java Preferences API to store window position and size of Swing application. At this moment, I'm listening to window resize/reposition events and storing the position and size every time they change. However, that means that if user slowly resizes window which is 200px wide to 400px wide, I'll probably write new window size about 200 times during pretty short time. Preferences API uses whichever datastore is available on the host system (windows registry for Windows etc.) - but the question is, what are limitations or best practices for properties API? Is it OK, or would it be smart to write only when user has finished resizing? Anyone had experiences with Properties API on different platforms?

• Mouse Icon Distorted on Secondary Display

  - by Nathan Taylor

  I have a strange issue with a dual monitor, extended desktop setup where the mouse is always fine on the primary monitor, but sometimes when I move to the secondary display the icon becomes garbled and distorted (sometimes it just looks like a vertical line, instead of a pointer). If I move the mouse back and forth rapidly between primary and secondary displays the level of "garbledness" of the icon will change and sometimes go away completely. If I switch the display settings and set it to "Duplicate Monitor 1" then I end up with a garbled icon on the primary display and an accurate one on the secondary. Very annoying. Computer is Windows 7 Ultimate with an HD8750 and the newest video drivers. Monitors are two Dell 24" displays connected via DVI cables. I have also tried VGA cables.

• How to Practically Split Values from CSV File into MySQL Database

  - by Ryan

  Let's suppose I have the following line in a CSV file (I removed the header row in this example): "500,000",2,50,2,90000 I have a PHP script read the CSV file, break the file into individual lines, and store each line in an array called $linearray. Then, I use a foreach loop to look at each line individually. Within the foreach loop, I break the line into separate variables using the following function: $line = str_replace("'","\'",$line); From here, I insert the values into separate columns within a MySQL database. The script works. The values are inserted into a database, but I run into a problem. I want: "500,000" | 2 | 50 | 2 | 90000 But I get this: "500 | 000" | 2 | 50 | 2 | 90000 The script isn't smart enough to understand it should skip commas within quotation marks. Do you know how I can alter my script to make sure I get the output I'm looking for? Thanks.

• Adding a div layer on top of a jquery carousel. Tough one.

  - by wilwaldon

  Hey everyone, I have a tough one, well it's tough for me because I'm kinda new to the whole jQuery carousel thing, never built one before this project. Here's my problem. If you go to the TEST SITE you will see a scroller with a blue background about half way down the page. If you mouse onto the "data analytics" slide you should see a black box fade in. Here is my dilemma. I want that black box to be a menu that's connected to the data analytics slide. I've done a mock up for you so you can see what I'm talking about. Here is my scroller code. I'm using jCarousel. <div class="carousel"> <ul> <li> <div id="homeslide1"> testers sdfasdfasdfas asdftjhs iasndkad kasdnf <a href="#" id="#homeslide1-toggle">Close this</a> </div> <a href="#" id="homeslide1-show"><img src="<?php bloginfo('template_url'); ?>/images/home_data_analytics.jpg" width="200" height="94" /></a> </li> <li><img src="<?php bloginfo('template_url'); ?>/images/home_oem_partnerships.jpg" width="200" height="94" /></li> <li><img src="<?php bloginfo('template_url'); ?>/images/home_reporting.jpg" width="200" height="92" /></li> <li><img src="<?php bloginfo('template_url'); ?>/images/home_returning_lost_customers.jpg" width="200" height="92" /></li> <li><img src="<?php bloginfo('template_url'); ?>/images/home_sales.jpg" width="200" height="92" /></li> <li><img src="<?php bloginfo('template_url'); ?>/images/home_service_retention.jpg" width="200" height="92" /></li> </ul> Here is my scroller css /*HOMEPAGE SCROLLER*/ .carousel {!important padding:10px; width: 890px; margin: 0px 0px 0px 26px;} .carousel ul li element.style{height: 94px;} .carousel ul{width: 200px; padding: 5px;} .carouselitem{height: 94px;} .prev{background: url(images/home_left_scroll.png); height: 94px; width: 16px; text-indent: -999px; outline: none; cursor:pointer; float: left;} .next{background: url(images/home_right_scroll.png); height: 94px; width: 16px; text-indent: -999px; outline: none; cursor:pointer; float: right;} .carousel ul li{ padding: 0px 3px 0px 3px; margin: 0px; height:!important 94px; } .home_right_arrow{ width: 16px; float: right;} .home_left_arrow{ width: 16px; float: left;} .homeslide1{ width: 200px; height: 94px;} I've tried all sorts of z-index tricks but can't seem to figure it out on my own. If you solve this riddle I'll buy you a beer if we ever meet up. I'll also give you a high five through the internet. Is there a simple way to do this via jQuery? If so could you point me in the right direction? Thanks so much.

• Mac OS X Snow Leopard hangs after login

  - by sleepyjames

  After restoring from backup following filesystem corruption my user account hangs after login (After entering my password the login window disappears and all I get is the background and a mouse pointer, no spinning wheel of death etc ..) I can login as a different user and then logout and login as my main account (sometimes!) but this is not consistant. I can login with safemode ok and have tried deleting /System/Caches, ~/Library/Caches and removing all my ~/Library/Preferences which worked once but not again. Does anyone have an any idea which logs I can look in, if any, to see whats happening after login or any other tips? I'm using 10.6.2. Cheers.

• Arrays in database tables and normalization

  - by Ivan Petrov

  Hi! Is it smart to keep arrays in table columns? More precisely I am thinking of the following schema which to my understanding violates normalization: create table Permissions( GroupID int not null default(-1), CategoryID int not null default(-1), Permissions varchar(max) not null default(''), constraint PK_GroupCategory primary key clustered(GroupID,CategoryID) ); and this: create table Permissions( GroupID int not null default(-1), CategoryID int not null default(-1), PermissionID int not null default(-1), constraint PK_GroupCategory primary key clustered(GroupID,CategoryID) ); UPD: Forgot to mention, in the scope of this concrete question we will consider that the "fetch rows that have permission X" won't be performed, instead all the lookups will be made by GroupID and CategoryID only Thoughts? Thanks in advance!

• Python command line UI

  - by hdx

  Hey guys/gals I'm writing a python script that fixes some duplicate issues on my database. I would like to display some progress status to the users, currently I just print it like this: print "Merged " + str(idx) + " out of " + str(totalCount); The problem is that it prints that in a new line for every record and that does not look so good :) I'd like to either always print the string above on the same line on the screen or use some smart widget that displays it in some sort of progress bar. I intent to run this on the command line, any suggestions will be much appreciated.

• What's the best example of pure show-off code you've seen?

  - by Damovisa

  Let's face it, programmers can be show-offs. I've seen a lot of code that was only done a particular way to prove how smart the person who wrote it was. What's the best example of pure show-off code you've seen (or been responsible for) in your time? For me, it'd have to be the guy who wrote FizzBuzz in one line on a whiteboard during a programming interview. Not really that impressive in the scheme of things, but completely unnecessary and pure, "look-what-I-can-do". I've lost the original code, but I think it was something like this (linebreaks for readability): Enumerable.Range(1,100).ToList().ForEach( n => Console.WriteLine( (n%3==0) ? (n%5==0) ? "FizzBuzz" : "Fizz" : (n%5==0) ? "Buzz" : n ) );

• Windows CE vs Windows Mobile

  - by Vaccano

  I often see these terms: Windows CE Windows Mobile Pocket PC Windows Mobile Smart Phone I know the difference between the second 2, but I am confused on the first. I thought it was the name of the Mobile OS prior to Windows Mobile 5. But I am seeing it more often in current products. (Here is a current MS Form for developing on it. Here is a current product for creating them.) What is it and how does it relate to the Windows Mobile lines?

• Will there be IQueryable-like additions to IObservable? (.NET Rx)

  - by Jason

  The new IObservable/IObserver frameworks in the System.Reactive library coming in .NET 4.0 are very exciting (see this and this link). It may be too early to speculate, but will there also be a (for lack of a better term) IQueryable-like framework built for these new interfaces as well? One particular use case would be to assist in pre-processing events at the source, rather than in the chain of the receiving calls. For example, if you have a very 'chatty' event interface, using the Subscribe().Where(...) will receive all events through the pipeline and the client does the filtering. What I am wondering is if there will be something akin to IQueryableObservable, whereby these LINQ methods will be 'compiled' into some 'smart' Subscribe implementation in a source. I can imagine certain network server architectures that could use such a framework. Or how about an add-on to SQL Server (or any RDBMS for that matter) that would allow .NET code to receive new data notifications (triggers in code) and would need those notifications filtered server-side.

• How to use symbolic links in windows server 2008R2 across the network (mklink)

No I would like to transfer all the data von Serv1 to Serv2 and have links to the new destination. I found mklink very useful here but unfortunately it does not work over the network. Which also points the docu out. People heavily rely on the path's so it would be helpful if somone has a pointer for me... how to handle symbolic links a cross the network with Windows Servers.

• Ubuntu freezes when gdm starts showing userlist

  - by Enrique Becerra

  I have Ubuntu 10.10 (upgraded from 10.04) I was browsing in Firefox yesterday, then the PC did a suddenly reset Once I restarted, everything went normal until gdm begun showing. Then everything froze and locked when userlist showed. I could not move mouse pointer nor do anything with keyboard. Both, mouse and keyboard work fine, because this Ubuntu is dual-booting with a Windows XP install which loads/works fine. Here is my .xsession-errors file, but I don't have a clue what may be wrong. Thanks http://pastebin.com/GVtneEAF

• Help on using mod_rewrite to serve I18N static site

  - by Guandalino

  My static site www.example.com is translated in different languages and files are organized in this hierarchy: / /de index.html seite-1.html /en index.html page-1.html /it index.html pagina-1.html The root contains no files, just one subdirectory for each language the site is translated in, while subdirectories contain pages translated (both content and file name are) in the language corresponding to subdirectory name, de, en, it, etc. The question is: how to configure mod_rewrite so that when a client visits www.example.com it is taken to the correct version of the site, falling back to english version if the required locale is not supported (i.e. Accept-Language header doesn't exist or specifies a language for which the site is not available, e.g. fr)? Thanks for any pointer, I'm here to provide further details or feedback! Best regards

• Formula needed: Sort Array

  - by aw

  I have the following array: a = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16] I use it for some visual stuff like this: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Now I want to sort the array like this: 1 3 6 10 2 5 9 13 4 8 12 15 7 11 14 16 //So the original array should look like this: a = [1,5,2,9,6,3,13,10,7,4,14,11,8,15,12,16] Yeah, now I'm looking for a smart formula to do that ticker = 0; originalArray = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16] newArray = []; while(ticker < originalArray.length) { //do the magic here ticker++; }

• Using ROBOCOPY to MOVE data around, not copy it

  - by Nate Bross

  I have the following powershell script, which executes a few robocopy commands: ROBOCOPY.exe $q3 $q4 /R:5 /W:15 /S /NP /MT:32 /XA:SH /XJD ROBOCOPY.exe $q2 $q3 /R:5 /W:15 /S /NP /MT:32 /XA:SH /XJD ROBOCOPY.exe $q1 $q2 /R:5 /W:15 /S /NP /MT:32 /XA:SH /XJD ROBOCOPY.exe $src $q1 /R:5 /W:15 /S /NP /MT:32 /XA:SH /XJD This works fine, but it takes a really long time, I'm wondering, if there is a way that I can have robocopy do a "cut + paste" instead of a "copy + paste" so windows will move the NTFS pointer to the file, instead of actually copying all of the bits of each file?

• How secure are GUIDs in terms of predictability?

  - by ssg

  We're using .NET's Guid.NewGuid() to generate activation codes and API keys currently. I wonder if that poses a security problem since their algorithm is open. .NET Guid uses Win32 CoCreateGuid and I don't know it's internals (possibly MAC address + timestamp?). Can someone derive a second GUID out of the first one, or can he hit it with some smart guesses or is the randomness good enough so search space becomes too big? Generating random keys have the problem of collision, they need a double check before adding to a database. That's why we stuck with GUIDs but I'm unsure about their security for these purposes. Here are the 4 consecutive UUIDGEN outputs: c44dc549-5d92-4330-b451-b29a87848993 d56d4c8d-bfba-4b95-8332-e86d7f204c1c 63cdf958-9d5a-4b63-ae65-74e4237888ea 6fd09369-0fbd-456d-9c06-27fef4c8eca5 Here are 4 of them by Guid.NewGuid(): 0652b193-64c6-4c5e-ad06-9990e1ee3791 374b6313-34a0-4c28-b336-bb2ecd879d0f 3c5a345f-3865-4420-a62c-1cdfd2defed9 5b09d7dc-8546-4ccf-9c85-de0bf4f43bf0

• Vendor neutral SQL

  - by Sparafusile

  I'm currently working on a project for a web application that may be installed on several different servers with various software configurations. I want to make my application as flexible as possible by allowing the user to have various SQL servers installed. The problem is the SQL syntax used by any two server vendors does not match up. For a simple example, here is the same SELECT statement for MS SQL and MySQL: MS SQL - SELECT TOP 1 * FROM MyTable ORDER BY DateCreated DESC MySQL - SELECT * FROM MyTable ORDER BY DateCreated DESC LIMIT 1 Are there any standard way to abstract the statement creation for various vendors? Any online resources or books discussing this problem? Any hints or smart-alec remarks that I'd find useful? Further information: I'm writing my we application in vanilla ASP running on a Windows server. Thanks, Spara

• Repeatedly querying xml using python

  - by Jack

  I have some xml documents I need to run queries on. I've created some python scripts (using ElementTree) to do this, since I'm vaguely familiar with using it. The way it works is I run the scripts several times with different arguments, depending on what I want to find out. These files can be relatively large (10MB+) and so it takes rather a long time to parse them. On my system, just running: tree = ElementTree.parse(document) takes around 30 seconds, with a subsequent findall query only adding around a second to that. Seeing as the way I'm doing this requires me to repeatedly parse the file, I was wondering if there was some sort of caching mechanism I can use so that the ElementTree.parse computation can be reduced on subsequent queries. I realise the smart thing to do here may be to try and batch as many queries as possible together in the python script, but I was hoping there might be another way. Thanks.
