• Apache configuration file visualization/testing

  - by Matt Holgate

  Is there a tool available (or a debug mode built into Apache) that will allow me to interactively test and explain an Apache configuration for a given request? In particular, I'd like to be able to see which directives will apply when requesting a specific URL. For example, the output for the URL http://myserver.com/foo/bar/bar.html might look something like: Allow from 192.168.0.3 <-- From <Location /foo/bar> in myserver.com vhost Require valid user <-- From <Directory /var/www/foo> in global configuration Satisfy any <-- From <File bar.html> in global configuration [Background: why do I want this? The apache merging rules for configuration directives are quite complex to get right. It would be great to have a tool which allows you to check that your rules are doing exactly what you want, and would be a good learning tool]. If there isn't such a tool, is there a debug option in Apache that will log such information for each incoming request?

• How to mount a iSCSI/SAN storage drive to a stable device name (one that can't change on re-connect)?

  - by jcalfee314

  We need stable device paths for our Twinstrata SAN drives. Many guides for setting up iSCSI connectors simply say to use a device path like /dev/sda or /dev/sdb. This is far from correct, I doubt that any setup exists that would be happy to have its device name suddenly change (from /dev/sda to /dev/sdb for example). The fix I found was to install multipath and start a multipathd on boot which then provides a stable mapping between the storage's WWID to a device path like this /dev/mapper/firebird_database. This is a method described in the CentOS/RedHat here: http://www.centos.org/docs/5/html/5.1/DM_Multipath/setup_procedure.html. This seems a little complicated though. We noticed that it is common to see UUIDs appear in fstab on new installs. So, the question is, why do we need an external program (multipathd) running to provide a stable device mount? Should there be a way to provide the WWID directly in /etc/fstab?

• What technologies are needed to be a freelance web developer / designer targeting small businesses?

  - by Jason Wirth

  First off, I'm not looking for this answer: "learn PHP/MySQL, JQuery, HTML/CSS...." My background, I wear many hats, and do many things. Currently I manage investment accounts with a business partner who is also a friend. He happens to be attending business / law school perusing a joint JD and MBA. As a result, we're putting our into "coast", maintaining our current clients, but not acquiring more. Recently I've picked up some freelance graphic design / web development / online marketing side work (Photoshop, HTML/CSS, WordPress) through some personal networks. The work is enjoyable; now I'm thinking about expanding it into a larger business with these primary goals: augment my finances (I'm shooting for about $1,000-2,000 per mo.), learn new technologies, involve myself with meaningful work. As an entrepreneur I don't mind the aspects of running a business that hassle other freelancers... -- the marketing -- the billing -- etc. I'm considering targeting the small to middle market businesses and organizations where I can contribute in marketing, design, and development building projects from the ground up. Thus I'll have freedom to decide the specific technology (I won't have to work with an existing code base). What kinds of projects should I focus on? What technologies are a good fit for this style of work? For example: It might be fun to develop with Ruby on Rails. However, maybe a lot of projects would be rolling out e-commerce solutions. Thus, I should focus on PHP due to more shopping cart options, skipping ROR entirely.

• How do I troubleshoot a page not found error when configuring IIS6 Windows Server 2003? [Page Not Found]

  - by Vinicius Ottoni

  I have configured IIS6 in my windows server 2003 with this link: http://www.simongibson.com/intranet/iis6/ After that I create a new web site inside Web Sites directory. Inside the physical path I created an index.htm that has: <html> <body>Test</body> </html> But I got the following error: "The page cannot be found". When I put the same index file inside the Web Site Default physical path, it works. I configured the new web site with the link above using the IP configuration and without a Host Header.' What should I do to troubleshoot this or is there an obvious configuration error?

• Is there a formula for this?

  - by Gortron

  TL/DR: Any way to work out if known numbers between a known start and ending figure should be positive or negative numbers? I am developing an application in PHP which can import and read PDFs. The PDFs are financial ones such as bank statements with records of transactions in and out of a bank account. I only have PDFs to work with, no other formats such as CSV unfortunately. I convert the PDF to HTML using pdftohtml and start parsing the data, the intended end result is an array of transactions. So far I have it working smoothly collecting dates, descriptions and balance. Converting the XML instead doesn't help. There are other pieces of transcriptional data such as debit or credit amounts. In the PDF, the credit amount is in one column and the debit amount is in another column so it is quite clear in the PDF. However, when converted to HTML, the formatting is lost and therefor I don't know if the amount was a credit or debit amount. So, my question is, given a starting balance and an ending balance and several known figures in between, is it possible for a programme to work out if those known figures in between are credit or debit amounts? I imagine there could potentially be several combinations of those known values to reach the ending balance so I'd like to apply a formula to return the correct credit/debit sequence only if its the only possible solution. If there are several ways of adding/subtracting the known values to reach the end balance, I can ask the user to look at it manually but I'd like to keep this to a minimum if possible. Possible to do, do you think? Thank you in advance for any help.

• Start TLS and 389 Directory

  - by Kyle Flavin

  I'm trying to configure Start TLS on 389 Directory server, but I'm having all sorts of issues. I've been following this doc: https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Directory_Server/9.0/html/Administration_Guide/managing-certs.html which specifies that I should create a certificate for both the directory server and admin server. I've imported the CA cert on both servers. I've tried to use the same server certificate for both. It will not allow me to do so. However, the admin and directory servers reside on the same host. If I generate a new certificate it will need to use the same hostname. I'm not sure if that's valid... Has anyone out there set this up before? Any direction would be helpful. I have multmaster replication set up. From an external client, I'm attempting to do an ldapsearch -ZZ -x -h "myhost" -b "dc=example,dc=com" -D "cn=Directory Manager" -W "", and I'm getting a protocol error.

• What should a programmer's yearly routine be to maximize their technical skills?

  - by sguptaet

  2 years ago I made a big career change into programming. I learned various technologies on my own without any prior experience. I really love it and feel lucky with all the resources around us to help us learn. Books, courses, open-source, etc. There are so many avenues. I'm wondering what a good routine would be to follow to maximize my software development skills. I don't believe just building software is the way, because that leaves no time for learning new concepts or technologies. I'm looking for an answer like this: Take a new concept sabbatical/workshop 2 weeks per year. Read 1 theoretical and 1 practical programming book per year. Learn 1 additional language every 2 years. Take a 1 week vacation every 6 months. Etc. I realize that the above might sound naive and unrealistic as there are so many factors. But I'd like to know the "recipe" that you think is best that will serve as a guide for people.

• Apache httpd VirtualHost config - multiple sites

  - by DaFoot

  [Advised to post here from StackExchange] I have a site to work on, because of the way the URLs are built the application seems to have been created on the assumption that it will be at the server root (only app). On my dev server I have other projects and up to now a simple symlink has been working for me, but that's not the case now because this new app wants to sit at the route and process all URLs arriving on :80. Hopefully this snippet from httpd.conf will help explain what I'm trying to acheive: # default for any not matched elsewhere <VirtualHost *:80> ServerName localhost DocumentRoot /var/www/html/newproject </VirtualHost> # now try to pick out specific URLs <VirtualHost localhost/webdev> DocumentRoot /var/www/html/existingProject ServerName localhost/project </VirtualHost> Also need to be able to get same affect from wherever I'm accessing the httpd instance from. Hope that makes sense.

• How to rewrite index.php (and other valid default files) to the document root using mod_rewrite?

  - by TMG

  Hello, I would like to redirect index.php, as well as any other valid default file (e.g. index.html, index.asp, etc.) to the document root (which contains index.php) with something like this: RewriteRule ^index\.(php|htm|html|asp|cfm|shtml|shtm)/?$ / [NC,L] However, this is of course giving me an infinite redirect loop. What's the right way to do this? If possible, I'd like to have this work in both the development and production environment, so I don't want to specify an explicit url like http://www.mysite.com/ as the target. Thanks!

• IE 9:Release

  - by xamlnotes

  Yippie: IE 9s coming out March 14!: http://windowsteamblog.com/ie/b/ie/archive/2011/03/09/a-more-beautiful-web-launches-on-march-14th.aspx For you guys that love other browsers that’s ok. Personally I love IE for many reasons such as ease of use and stability.  I am cranked up to see what IE 9 does as it was retooled from the start. So this one should be big. Also, its bringing HTML 5 support now so we can have much richer applications. Its about time that HTML was revved to move from the old text like stuff to a better model. More info: http://windowsteamblog.com/ie/b/ie/archive/tags/ie9/ Some glimpses here: http://windows.microsoft.com/en-US/internet-explorer/products/ie-9/features and http://www.beautyoftheweb.com/#/highlights/all-around-fast   Looks like it will be much faster (with hardware support now) in many areas.  Better startup times and install times are hot on my list of favorites too. Plus they retooled the UI in many places too.  The UI looks a lot cleaner now: http://windows.microsoft.com/en-US/internet-explorer/products/ie-9/features/focused-on-your-websites Plus theres tons more like changes in tab pages, a notfication bar, pinned sites and so forth. Plus theres cool integration with Windows 7 also.

• Thunderbird: filters don't match links

  - by Gregory MOUSSAT

  I use filters to remove some undesirable messages (in addition to the intergrated spam filter). This is great to avoid tons of boring people who want to sell me tons of boring stuff. My problem is, since years (so with every Thunderbird release I ever had, even the current one which is up to date) it is unable to filter links. For example I want to delete every messages containing a link to http://xxxxx.emv3.com/xxxxxx I never managed to remove those emails. I use a filter on the body, checking if it contains emv3 but this never match. Those emails are in HTML format, and the links are displayed as a text like "Visit our website" or so. If I write a HTML email with a link, my filter works. When this is a spam, this never works. When I save the email to a text file, I open it with notepad and I see several http://xxxxx.emv3.com/xxxx Any idea why this don't work ? And how can I do ?

  Possible Duplicate: What physical tools do you find useful to work as a programmer?

I'm starting out in a corporate environment and want to have an understanding of what tools really work for other programmers to help them work through their problems and solutions.

• Make words look like keystrokes in Microsoft Word

  - by techturtle

  Is there an easy way in Microsoft Word 2010 to make words appear like keystrokes the way we can here in Superuser? Something like this: Ctrl + V I know that <kbd> is an HTML tag, but in normal HTML that just switches to a fixed-width font. In fact, that's how Word treats it if you paste something from SU into a Word doc: If there's not a standard way to do this in Word, is there a free font that might accomplish the same thing? I thought I'd seen some before but couldn't find any at the regular places I find fonts (dafont.com, fontspace.com).
