• What's the big deal with brute force on hashes like MD5

  - by Jan Kuboschek

  I just spent some time reading http://stackoverflow.com/questions/2768248/is-md5-really-that-bad (I highly recommend!). In it, it talks about hash collisions. Maybe I'm missing something here, but can't you just encrypt your password using, say, MD5 and then, say, SHA-1 (or any other, doesn't matter.) Wouldn't this increase the processing power required to brute-force the hash and reduce the possibility of collision?

• How do I clone an OpenLDAP database

  - by elzapp

  I know this is more like a serverfault question than a stackoverflow question, but since serverfault isn't up yet, here I go: I'm supposed to move an application from one redhat server to another, and without very good knowledge of the internal workings of the application, how would I move the OpenLDAP database from the one machine to the other, with schemas and all. What files would I need to copy over? I believe the setup is pretty standard.

• Is the W3 standard a major factor when google decides SERP position?

  - by Camran

  I have a dynamic php website which index only has around 800 errors according to the w3 validator online. I have tried checking major websites like ebay, stackoverflow and others also, all with around 400 errors. So my first thought is, what good is that validator when it always displays errors? Secondly, will the errors affect my SERP ranking? ie, will me fixing these errors as good as I can increase my Google search position? Thanks

  I've got thousands of urls from many hosts I need to screenshot. I can use the lib fine from the command line, but how can I integrate it into my code so I can take multiple screenshots simultaneously?

• Ignore deleted files in git?

  - by matthavener

  Is it possible to ignore deleted files in git? git update-index --assume-unchanged allows me to ignore modifications, but it still tracks deletions.

• Does setting HttpCacheability.Public also cache the page on the server?

  - by Stewart Robinson

  I have these lines in my global.asax (basically because of http://stackoverflow.com/questions/2469348/can-i-add-my-caching-lines-to-global-asax) The thing I want to now understand is whether this code purely adds the HTTP headers to the page or does it also make .Net cache this page on the server for 300 seconds? Response.Cache.SetExpires(DateTime.Now.AddSeconds(300)); Response.Cache.SetCacheability(HttpCacheability.Public);

  - by Chuck Savage

  Which of the two of these are preferable (and why) from the service installer, I've seen both mentioned on different websites (and here on stackoverflow Automatically start a Windows Service on install and How to automatically start your service after install?). // Auto Start the Service Once Installation is Finished. this.AfterInstall += (s, e) => new ServiceController("service").Start(); this.Committed += (s, e) => new ServiceController("service").Start();

• Why is there no middleware in Erlang?

  - by Zubair

  I asked a question earlier about ESBs written in Erlang or Java, and there didn't seem to be anything in Erlang, and only products in Java. http://stackoverflow.com/questions/2453641/what-would-be-the-best-language-in-which-to-write-an-esb/2453683#2453683 I guess I find it difficult to understand why a language like Erlang has no such middleware products, especially seeing as it should be ideally suited to the job.

  I know from reading this: http://stackoverflow.com/questions/1230457/is-there-a-size-limit-for-ota-android-market-downloads/1232145#1232145 That there wasn't a limit to the size of an application that could be downloaded over the air (OTA) but I wonder if a limit, like that imposed by the Apple App Store (20MB) exists now that the Nexus one is running on AT&T's 3G network as of today.
