• Why are PNG-8 files mangled when opened in Photoshop?

  - by Daniel Beardsley

  Why are some 32 bit PNGs opened in Photoshop with Indexed Colors and no transparency? For instance, I grabbed a png icon file of the Stack Overflow logo at: http://blog.stackoverflow.com/wp-content/uploads/icon-so.png When opening it in Photoshop CS3, it apparently treats it as indexed color and gets rid of the alpha channel. The image on the right is a screen grab of the icon. Changing the Image mode in Photoshop to RGB doesn't change the image at all. I've tried this with a few other PNGs and it seems hit or miss. When viewed in other programs, it displays fine. left:png opened in Photoshop, right:screen grab of png from browser What gives?, does Photoshop not interpret the PNG file format correctly?

• Using Postgres on Volusion site

  - by Sean

  Okay, I apologize if this is so basic that I should know the answer, but I'm not sure where else to go for the solution. I would like to start a small store site using Volusion. I would like some custom ASP code to query data that I currently have in a Postgres database. I would like to be able to just move the database file(s) onto the Volusion server via ftp and access them from my store site (via the custom ASP). Do I need to install Postgres onto the server to do this, or can I just ftp my database file(s) and access them with the ASP code? I think I need to install Postgres, but would like to do this without such an installation if possible.

• Unable to get to remote samba share

  - by tubaguy50035

  I have a remote VPS that I would like to setup samba on and only allow my IP access to it. I currently have in my smb.conf: [global] netbios name = apollo security = user encrypt passwords = true socket options = TCP_NODELAY printing = bsd log level = 3 log file = /var/log/samba/log/%m debug timestamp = yes max log size = 100 [hosting] path = /hosting/ comment = Hosting Folder browseable = yes read only = yes guest account = yes valid users = nick I have the ports (137,138,139,445) open in iptables (they're open to everyone right now while I debug) and I see nothing in the syslog about iptables blocking my requests. When I try to open a file browser to my address \\ipaddress, it hangs for a good thirty seconds, and then opens a log in box. I enter my user name and password for the server, hit okay. It then opens the same box, I enter my credentials again and hit enter. Windows then tells me it could not connect. My user account is added to Samba already. Anybody have any suggestions what I can do to get this working?

• In linux: how to exit a program but not kill it?

  - by biomed

  I use Ubuntu 10.10 and I have a python program (mnemosyne) that I synchronize the data files using dropbox. If I forget to close (exit) this program. Here is my problem scenario. I leave the program running at home and go to work but if I open the program at work and work on it the data file is changed and I loose my progress at home when I exit (it automatically saves) when exitimg. I thought I could create a cron job to automatically close mnemosyne every morning regardless os me remembering to do it or not but if I use kill the program exits without saving the datafile and I end up with a tmp file and an error message when I restart it. Is there a better way of sending the exit signal to this program emulating me clicking fileexit menu option. Thanks

• SSH automatic logon works for one user but not the other

  - by tinmaru

  I want to enable automatic ssh login using the .ssh/config file for my git user. Here is my .ssh/config file: Host test HostName myserver.net User test IdentityFile ~/.ssh/id_rsa Host git HostName myserver.net User git IdentityFile ~/.ssh/id_rsa It works for my test user but not for my git user so my global SSH configuration is correct. The configuration are exactly the same as far as I know. It used to work with git user but I'm unable what change has broken the automatic logon. When I type: ssh -v git I get the following log: ... debug1: Authentications that can continue: publickey,password debug1: Next authentication method: publickey Offering RSA public key: /Users/mylocalusername/.ssh/id_rsa debug1: Authentications that can continue: publickey,password debug1: Next authentication method: password [email protected]'s password: _ Does anyone know what could be a possible difference

• Gitosis installation of public key not working...

  - by user29600

  I've been following this tutorial to install and setup git on Ubuntu Server 10.04 using Windows 7 as a client. However, after finally figuring out how it works (executed gitosis-init a bunch of times on the wrong key), I copied the id_rsa.pub file over to the server in /tmp folder and ran it again. Unfortunately it still doesn't work and when I execute git clone [email protected]:gitosis-admin.git it asks for gitosis's password rather than the RSA Passphrase. I'm assuming is the same problem this guy is having here... however, after following his instructions: Purge git-core and gitosis and manually remove the /srv/gitosis folder and following the instructions again (with the proper id_rsa.pub file this time), I'm still having the same issue. Anyone know what I'm doing wrong? Is there any way to probe for more information that might help in solving this?

• Cannot copy anything onto WD Elements 1TB External USB HDD

  - by Aashish Vaghela

  I have a Western Digital 1023 Elements 1TB External USB HDD. Recently, it has started an unusual problem. I cannot copy any file of any size on to that 1TB hard-drive, eventhough it has more than 400 GB free (out of 931GB actual size). I tried copying movies from one friends laptop, which did not work. I also tried another desktop to copy some study material e-books (in PDF), which also did not work. I get same CRC error when I try to copy anything from a computer's hard-drive onto this WD 1TB hard-drive. Vice-versa it's working. I mean, I can copy any file from the USB HDD onto local machine's HDD on any computer. It's like one-way traffic. This HDD is only 1 year old. What are my options ? Any suggestions ? Regards, Aashish.V

• Difference between SSLCertificateFile and SSLCertificateChainFile?

  - by chrisjlee

  Normally with a virtual host an ssl is setup with the following directives: Listen 443 SSLCertificateFile /home/web/certs/domain1.public.crt SSLCertificateKeyFile /home/web/certs/domain1.private.key SSLCertificateChainFile /home/web/certs/domain1.intermediate.crt From: For enabling SSL for a single domain on a server with muliple vhosts, will this configuration work? What is the difference between SSLCertificateFile and SSLCertificateChainFile ? The client has purchased a CA key from GoDaddy. It looks like GoDaddy only provides a SSLCertificateFile (.crt file), and a SSLCertificateKeyFile (.key file) and not at SSLCertificateChainFile. Will my ssl still work without a SSLCertificateChainFile path specified ? Also, is there a canonical path where these files should be placed?

  - by YeppThat'sMe

  gurus. I have a problem and i dont know how to solve it. I am working with Git and Compass/SASS on some projects. Now i want to protect those directories.

Same scenario with compass. There is a config.rb file within the folder which also starts to download it. How can i prevent this behaviour? How can i deny downloading specific files?

• Where is the list of available Windows locales?

  - by Richard Cotton

  If you open the Regional and Language Options (via Control Panel), and click on the Regional Options tab, then there is a drop down list of all the available locales. Where is this list populated from? (I want to compare the settings for each locale; I'm fine with how to do that, but I need a list of locale names to loop over.) EDIT: After browsing through my windows directory (should probably mention I'm using XP), the file C:\WINDOWS\system32\locale.nls looks like a plausible candidate, but it's a binary file. Is this what I should be looking at, and if so, how do I read it?

• DosBox Booting From HDD Image, FreeDOS Image created with qemu-img.

  - by TechZilla

  I'm having trouble booting a HDD image with DosBox. I've only gotten either read errors, or boot failures. The HDD image is a verified working FreeDOS installation, created with qemu-img. The image has been formatted FAT32, and it's working as expected with QEMU. The Image is only 1G in size, and is a flat raw image. I have been able to mount it with Linux, for ease of file transfer. I even was able to boot with DOSEMU, After I mounted the image under Linux. I would love to somehow just boot from the raw image file, but I would have no problem booting from a mount. I just can't get anything to happen, and I have read the Documents over. I have verified DosBox is working as expected, with its included DOSlike environment. I would appreciate any help, as I just don't have much of DosBox experience.

• What are the components required to run taskpads on a workstation?

  - by Darktux

  we are planning to implement task pads in our enviroment for delegation for user administration.I have few questions regarding this. 1.) To run a taskpad (with AD users and computers) ; does the workstation contain whole set of Administrative tools oris there a way just to compy dsa.msc to all workstations and get done with? Note: All tak pads will be shared on a file share and users access them via powershell scripts. 2.) We are creating MMC's in Windows 7 and keeeping them in a share; will the work with Windows XP too or do we need to develop 2 versions of them? We are aiming to keep away software from workstations and maintain it as much as possible on centralized file shares. Please shoot me any questions or clarifications pertaining to my query.

• .bashrc doesn't get sourced after su'ing to root

  - by Ian Dunn

  I've got a CentOS 5.6 VPS and both root and my normal user account have identical copies of a .bashrc file in their home directories. The file contains a few basic aliases, etc. If I login to root, root's copy gets sourced. If I login to myuser, myuser's copy gets sourced If I su to root after logging into myuser, then all the aliases, etc inside myuser's copy get removed, and root's copy doesn't get sourced. If I then manually source root's copy, the command completes without any errors, but none of the aliases's etc get applied. I've searched Google and Server Fault, but haven't found any solutions. Does anyone know how to fix that?

• PowerPoint 2010 won't open any files.

  - by Samwho

  Recently I installed Office 2010 BETA on my friend's laptop after recommending it to her. The problem is, whenever she tries to open files in powerpoint it claims that there is a problem with them and it can attempt to repair them, when you click repair it just says there was a problem with the file and it can't open it. The exact same .ppt files work fine on my copy of PowerPoint 2010 (we sent the file from her laptop to mine via MSN) so I'm confused as to why they won't work just on her laptop. Any insight into this would be fantastic :) Thanks.

• Unloading uwsgi dynamic app

  - by Gevious

  I have a uWSGI setup where I run dynamic mode and add applications to it. All applications are working off the same codebase, but each have their own settings file. Its working beautifully. Say for instance, i want to change a setting for one app that has already been loaded. Is there a way I can get uwsgi to reload the app, rather than restarting the whole uwsgi server? In emperor mode I could just touch the config file. How do I achieve the equivalent result in dynamic mode?

• Sharepoint .PDF contents displaying as 'searchtext.xml' in searches

  - by Green Muffins

  Hi Experts, I recently used installed ifilter in my sharepoint farm to enable searching of the contents of .pdf documents. All went well, except if I search for contents of any .pdf file, they appear in the search results with document title "searchtext.xml", and the link to the document gives a giant page of the .pdf contents in an .xml looking browser page. :s I have added .pdf filetypes to the search, so I am unsure why it is reading them incorrectly.. if I search for a .pdf document title such as 'document.pdf' it will display the result as a html page, though the link does follow to a readable .pdf file. Any help?

• Where does a Quick-Time powered application store changes to the user interface?

  - by Luke

  I have downloaded an application written with the Quick Time library (for Windows 7). The application does not need an installation: just unzip it in a directory and run the program. It works, but I have a problem: the program allows the user to change a lot of values using its interface but does not have an option to reset them to their default values. What is more problematic is that when I exit the program and run it again, the interface still has the changed values. In the program directory there is no file that stores the changes done to the UI of the program. I suspect that Quick Time records these changes somewhere, but I can't find the right file. I have even deleted the application and re-unzipped it to another location - but the UI values still remain the same values changed by me!

• Commands not working in Windows 7 32-bit command prompt

  - by Precious Tijesunimi

  I have an HP laptop with a Windows 7 32-bit Home Premium operating system. My command prompt doesn't run lots of commands like help, shutdown, ipconfig, ping, etc. I get a message like: 'help' is not recognized as an internal or external command, operable program or batch file. Only simple commands like cd and dir are working. I noticed that whenever I navigate to c:/windows/system32, the command works. But I need to run some important commands like java on a file that is on the desktop and not in the system32 folder. How can I fix this?

• Why S3 website redirect location is not followed by CloudFront?

  - by ychaze

  I have a website hosted on Amazon S3. It is the new version of an old website hosted on WordPress. I have set up some files with the metadata Website Redirect Locationto handle old location and redirect them to the new website pages. For example: I had http://www.mysite.com/solution that I want to redirect to http://mysite.s3-website-us-east-1.amazonaws.com/product.html So I created an empty file named solutioninside my bucket with the correct metadata: Website Redirect Location= /product.html The S3 redirect metadata is equivalent to a 301 Moved Permanentlythat is great for SEO. This works great when accessing the URL directly from S3 domain. I have also set up a CloudFront distribution based on the website bucket. And when I try to access through my distribution, the redirect does not work, ie: http://xxxx123.cloudfront.net/solution does not redirect but download the empty file instead. So my question is how to keep the redirection through the CloudFront distribution ? Or any idea on how to handle the redirection without deteriorate SEO ? Thanks
