• Android market going down the drain?

  <b>Ian's Thoughts:</b> "You can search the Android Market for the following keywords and see quite a bit of content that I feel shouldn't be available to customers, and definitely not to children: nude, sex, porn, 18+, adults only, boobs, the android market seems to be turning into a porn hub."

• solr administration

  - by devrick0

  Does anyone have any notes for an sysadmin supporting solr? I'm looking for anything that might be useful for monitoring & metrics as well as troubleshooting. Some useful links I have found are: /solr/admin/stats.jsp and /solr/admin/analysis.jsp In the logs I have noticed, other than the query, "hits", "status" and "QTime" values. The documentation on what these mean is sparse at least based on the 100+ websites I have checked. QTime appears to be the query time response in milliseconds. Hits is some form of results but I'm not sure exactly what makes that up and I'm not sure about status. Typically I see status come back as "0" but I have seen other numbers such as "5", so my thoughts that it could be either HTTP status codes or a 0 or 1 (good or bad) methodology isn't accurate. All of the documentation I have come across is intended for developers. Any sysadmin-centric documentation would be a big help.

• Premature end of script headers

  - by Tony

  I often get a "premature end of script headers" error in my apache log which results to an internal 500 error. I understand what the error message means - that my application did not give the browser the headers it needs (and maybe nothing at all), but the odd thing is that this does not happen all the time. It actually usually happens the first few times I go to my website after a deploy. Could this be a memory issue? Does anyone know how to trouble shoot this? My apache log isn't really telling me anything. I am running a ruby site using the rails framework on ubuntu hardy. thank you!

• Tomcat cannot connect to MySQL on localhost

  - by David

  Hi, I have deployed an application on my Tomcat server with JDBC resources defined. What is puzzling me is that I can connect to the database (which is running locally on the server) only using the server's IP. When I change the resource host to localhost (or 127.0.0.1) then MySQL rejects the connection. I don't want to be connection via the server's IP but rather locally. What do I do? Thanks!

• Dell D620 Windows 7 Blank screen

  - by Dave Arkell

  When I installed Windows 7 on my Dell D620 it was all fine until a couple of days later most times when I either shut down or suspend (by closing the lid). When I unsuspend or startup the computer, there is often a completely blank screen (can't see post screen or anything), and restarting doesn't help. I've found that I can eventually bring it back up again by suspending and unsuspending a few times, but obviously this is not ideal. Has anyone else experienced this? I think it is a driver issue, that somehow the driver is putting the video card into a certain mode that it forgets how to get it back out of. Any ideas on a better solution than my switching off and on business? Edit: Turns out that the video card had burned out! IT managed to get me a new mainboard sorted for me.

• Is there a standard UNIX tool to repeat a command any number of times?

  - by Jørn Schou-Rode

  This is probably dead easy, but is there a simple way to write a command once in the console, and have it executed n times, where n is specified at runtime? Something like this: repeat 100 echo hello Does such command exist (assume typical Linux installation)? Or would I write to do some kind of loop in bash?

• Against the use of "if" statments. Is there always a "clean" alternative?

  - by Zubair

  I have recently seen alot of activity saying that "if" statements should be banned. However in some of the alternatives people are just doing an "if" statement but discussed as a "case" statement, or as an overloaded function in pattern matching languages. Is it really such a clean solution to replace a well understood concept with a more obscure one?

• php session not working (as with cookies disabled), but cookies are enabled for the domain. What oth

  - by SWilk

  Hi, I have a problem with a client, who cannot log in to our system. We have PHP-based B2B system, which uses cookies to store session-id. The client cannot log in and is redirected to the login page, without any error message. He claims he have cookies enabled in his Firefox. Also, if he had cookies disabled, my javascript would detect this and would show him an red, very descriptive error info. He does not seen anything like this. What else could have same effect on sessions like disabled cookies in browser? Are there any proxies which filters cookies? Any AV software, etc? What to look for? Our login form works for any other user without problems.

• CRSF token and Session replication with Tomcat and Apache

  - by technocool

  I have an J2EE compliant web application. I use a session based token to append a secondary id to all incoming link generated by my application. To prevent my application against CSRF attack, I validate the secondary id before I allow the user session to work off the subsequent page. Recently, while working with session replication mechanism implementation, I observed that on session failover, the generated secodary id is lost and the user get re directed to the login page/default page. Any suggestions on how I can ensure that the my generated secondary token id is not lost from the replicated session?

• How does PHP work - literature

  - by Ondrej Slinták

  I'm interested in literature (articles on internet, in magazines, books, podcasts - I don't really mind anything) that describes how PHP works internally, about its gotchas and perhaps some advanced functions. Is there anything like this out there? I tried to search on Google, but majority of articles were about starting with PHP and its basic functions. Any input is really welcome as I'm trying to understand the language internally - I'm tired of my mindless typing of code without understanding its essence.
