  • mysql_connect "bool $new_link = true" is very slow

    - by Mikk
    Hi, I'm using latest version of Xampp on 64bit Win7. The problem is that, when I use mysql_connect with "bool $new_link" set to true like so: mysql_connect('localhost', 'root', 'my_password', TRUE); script execution time increases dramatically (about 0,5 seconds per connection, and when I have 4 diffirent objects using different connections, it takes ~2 seconds). Is setting "bool $new_link" to true, generally a bad idea or could it just be some problem with my software configuration. Thank you.

  • 2-col layout, one col scrolls vertical, other is fixed. Both scroll horizontal.

    - by Victor P
    Im trying to do a 2 column layout where the left column is very long vertically, and the right column is very long horizontally. When I scroll vertically, I want to move up and down the left column while the right one stays fixed. When I scroll horizontally, both columns move left-right (normal behaviour) I hope this drawing explain it more (sorry for the bad quality): Is this possible to do using only css? If not, how can I do it with javascript? Thanks

  • How secure is Remote Desktop from OSX to Windows Server 2003?

    - by dwhsix
    It's unclear to me exactly how secure Remote Desktop access from OSX to a Windows Server 2003 machine is. Is the communication encrypted by default? What level of encryption? Are there best practices for making this as secure as possible? I found http://www.mobydisk.com/techres/securing_remote_desktop.html but it's unclear how much of that is still relevant for current versions of RDP and Windows Server. I know I can tunnel RDP over ssh, but is that overkill or redundant? Thanks...

  • Installing software at large organisation

    - by CJ7
    I have to give an MSI to a large organisation for it to install (presumably via GPO) on to some of their workstations that are running XP. I already know that my application is not allowed to write to the application folder. I realise it should be writing to the AppData folder. The organisation has allocated a folder on a server for the database files and other configuration files. This folder is referenced by UNC naming and not by mapped drives. My question is: based on normal practices, is my app likely to have the rights to create a sub-folder on this server? Is my app likely to have the rights to create files on this server?

  • May we have Ruby and Rails performance statistics? We're persuading the business to use Rails!

    - by thekingoftruth
    We're convincing our Products officer that we want to use JRuby on Rails, and we're having a hard time coming up with some statistics which show that: Coding time is less using Rails vs. say Struts or Zend Framework or what have you. Ruby (and JRuby in particular) performance isn't horrible (anymore). Rails performance isn't bad either. If you can get us some good stats quickly, we might have a chance!

  • PIX_FMT_YUYV422 8 bits conversion ffmpeg

    - by Sridhar
    Hi, I have a raw YUYV422 buffer with 8-bit 4:2:2 Component Y’CbCr format (Y0, Cb, Y1, Cr order). I know that ffmpeg's PIX_FMT_YUYV422 only handle 16-bit buffers.So I am getting Bad memory error when scaling that buffer into YUV420P. Can any one give me a clue, how can I use this buffer with ffmpeg to covert into YUV420. Thanks, Raghu

  • Steps to make sure network is not blacklisted...Again

    - by msindle
    I have an interesting issue. I have a client that just got blacklisted due to spam being sent out over the last 2 days. I have my firewall configured to only allow mail to go outbound on port 25 from our mail server (Exchange 2010) exclusively and I have verified that there are no open relay's on our transport rules. We are running Vipre Business and after running deep scans with updated definitions all computers come back clean. I ran a message tracking report on our Exchange server that shows all mail sent via the mail server over the last couple of weeks and didn't see anything malicious or out of the ordinary. I have also verified that there are no home devices or rouge computers on the network. For all practical purposes it appears that the network is clean, but we still wound up on 5 or 6 blacklists...Where should I start looking next? Is there a "best practices" guide that can help eradicate this issue? Thanks in advance! msindle

  • Control separate Menu Component

    - by dmschenk
    I'm trying to create a menu component for my flashbuilder app but when I separate the menu from the main application it stops working. Can someone show an example of how to do this? Also if this is a bad idea could some explain why? Thanks Dave

  • What is Erlang's concurrency model actually ?

    - by arun_suresh
    I was reading a paper recently Why Events are Bad. The paper is a comparative study of Event based and thread based highly concurrent servers and finally concludes stating that Threads are better than events in that scenario. I find that I am not able to classify what sort of concurrency model erlang exposes. Erlang provides Light Weight Processes, but those processes are suspended most of the time until it has received some event/message of some sort. /Arun

  • Eclipse vs Netbeans

    - by Zenzen
    Some time ago (~4-5months ago) I attented a lecture about JEE and at some point the lecturer started talking about webservices and how hard it is to create a good one because all the IDEs make them in a bit different way (or something like that) and that in general it's better to use Netbeans to create them as Eclipse has some issues, the thing is he didn't really say why Eclipse is bad. Now I'm wondering is what he said true and why, is it really better to use Netbeans for webservices and why?

  • Does splitting out Data, Logs, and TempDB matter using a SAN with SQL 2008

    - by MVCylon
    I'm not a server admin. So be gentle. But I was just at a conference and in one of the training classes the Instructor explained some SQL DBA best practices. One of which was to separate out Mdf,Ldf, and TempDB onto different drives to increase performance. Now at our office we have a san. The Sys Admins created 3 san drives one for data, one for Logs, and one for TempDB. My intuition tells me that was a wasted effort...was it? I don't know alot of the details, but if you ask i'll try to fill in any specs needed to answer this question accurately.

  • Refactor custom wizard to reduce flicker

    - by Matthew Brown
    I have implemented a custom wizard control in C# windows forms by creating a base form which has the shared components and then making child forms for each step of the process. I then have a class which hides/shows the child forms when you move from one step to another. The problem is that flickering is bad when moving between forms. Does anyone know a way to either keep this method and reduce the flicker or refactor it to make it use a single form (which should definitely reduce the flicker)?

  • Programming Language Choices for High Integrity Systems

    - by Finbarr
    What programming languages are a good choice for High Integrity Systems? An example of a bad choice is Java as there is a considerable amount of code that is inaccessible to the programmer. I am looking for examples of strongly typed, block structured languages where the programmer is responsible for 100% of the code, and there is as little interference from things like a JVM as possible. Compilers will obviously be an issue. Language must have a complete and unambiguous definition.

  • How do I publish a Power Point Presentation that is High Quality and no lag on the Web?

    - by Luke Hutton
    I have a ~22MB Power Point Presentation (2007) that I need to be presented on a website for viewing. The file contains audio over several slides and some embedded images. What is the best practices or best way to present the presentation so it gets delivered the quickest and best quality to users? Some ideas I've thought of are: Somehow compress the file (.wav audio files, images) into a smaller presentation and save it as a Power Point Show (pps) so users can download it and use the free Power Point viewer? Convert it to video format (.avi) or something and stream it off the web? (Hopefully freeware) Save it as a web page? (but then it's only viewable in IE I believe)

  • Optimal Disk Setup for OLTP SQL Server

    - by Chris
    We have a high transaction (lots of reads and writes) database server (running SQL 2005) that is currently set up with a RAID 1 OS partition (C:) and a RAID 5 data/log/tempdb partition (D:). The C: has 2 drives and the D: has 4 drives. The server has around 300 databases ranging from 10MB to 2GB in size. I have been reading up on best practices for partioning the disks, but would like some opinions on our setup since we are so limited in the number of disks. It seems like RAID 10 is popular, but I dont think we could use it with only 6 total disks to work with. Thanks. Update I went with 3 RAID 1 Partitions (2 disks each) Partition 1: OS, TempDB, Backups Partition 2: Logs Partition 3: Data

  • Does this introduce security vulnerabilities?

    I don't think I'm missing anything. Then again I'm kind of a newbie. def GET(self, filename): name = urllib.unquote(filename) full = path.abspath(path.join(STATIC_PATH, filename)) #Make sure request is not tricksy and tries to get out of #the directory, e.g. filename = "../.ssh/id_rsa".

  • Malicious crawler blocker for ASP.NET

    - by Marek
    I have just stumbled upon Bad Behavior - a plugin for PHP that promises to detect spam and malicious crawlers by preventing them from accessing the site at all. Does something similar exist for ASP.NET/ASP.NET MVC? I am interested in blocking access to the site altogether, not in detecting spam after it was posted.

  • C# Document Scanning

    - by ErocM
    I have a document storage application that I need to integrate with a scanner software or create one on my own. I have very limited funding so buying an expensive alternative isn't really an option. I thought about just linking to the customer's scanning software's executable and opening it when they want to scan but that just seems like a bad way of doing it. Anyone have any suggestions on how I do this? Thanks as usual, Eroc

  • Permissions to run a SharePoint 2010 Application Pool?

    - by Michael Stum
    I'm currently in the process of setting up a SharePoint 2010 farm. In my Dev Environments, I have one account that is Local Admin, Farm Administrator and runs all Application Pools. For Production Environment, I would like to go with best Security Practices and run the Web Applications (At least 2: Main Portal and My Sites) with separate Domain Accounts. It's been some time that I worked with IIS, and I remember that there were issues with accessing files in c:\inetpub by non-Admin users. On the other hand, SharePoint "automagically" sets most permissions anyway. Does anyone have some experience with which permissions I need to give to the domain account at minimum in order to work?
