• Rails, destroy if blank

  - by Joseph Silvashy

  This might sound odd, but is there a 'Rails way' to have a model destroyed if a certain attribute is blank? Say I have a model like tags with just a name attribute or something, if the user edits the tag and deletes all the text out of the name field in the form I'd like the model to just be deleted. I'm aware of the reject_if method, but that doesn't seem to work.

• Command to determine whether ZooKeeper Server is Leader or Follower

  - by utrecht

  Introduction A ZooKeeper Quorum consisting of three ZooKeeper servers has been created. The zoo.cfg located on all three ZooKeeper servers looks as follows: maxClientCnxns=50 # The number of milliseconds of each tick tickTime=2000 # The number of ticks that the initial # synchronization phase can take initLimit=10 # The number of ticks that can pass between # sending a request and getting an acknowledgement syncLimit=5 # the directory where the snapshot is stored. dataDir=/var/lib/zookeeper # the port at which the clients will connect clientPort=2181 server.1=ip1:2888:3888 server.2=ip2:2888:3888 server.3=ip3:2888:3888 It is clear that one of the three ZooKeeper servers will become the Leader and the others Followers. If the Leader ZooKeeper server has been shutdown the Leader election will start again. The aim is to check if another ZooKeeper server will become the Leader if the Leader server has been shut down. Question Which command needs to be issued to check whether a ZooKeeper server is a Leader or a Follower?

• Resources for Windows Phone 7 development

  - by geocoin

  Windows Phone 7 has just been unveiled and right now there is no publicly available information to non-privileged developers/partners. MS are announcing all details of the development chain at the Mix10 conference. So until then this could be a good starting point/collection of online resources as they appear EDIT: I've added the speculation tag so we can also accumulate speculation. Please mark speculative posts as such. once firm details are announced we can confirm or delete them

• Is it verified that iPad cannot create ad hoc wifi networks?

  - by godofbiscuits

  Has anyone been able to verify that the iPad cannot create an ad hoc network? It has different radio hardware (the fact that it does 802.11n demonstrates this) than the iPhones, which I thought was the reason that the iPhones could not create WiFi networks. I know this was sort of answered elsewhere, but I wanted it to get proper attention with its own question and by more tag coverage. Jeff, your god of biscuits. ;)

  Hi all, of all three choices (AIR+AJAX, +Flash, and +FLEX) I went on the AJAX route. But it seems that it can't show Flash embedded in HTML (using the traditional OBJECT tag). Is it by design? or my fault?

• df says disk is full, but it is not

  - by Chris

  On a virtualized server running Ubuntu 10.04, df reports the following: # df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 7.4G 7.0G 0 100% / none 498M 160K 498M 1% /dev none 500M 0 500M 0% /dev/shm none 500M 92K 500M 1% /var/run none 500M 0 500M 0% /var/lock none 500M 0 500M 0% /lib/init/rw /dev/sda3 917G 305G 566G 36% /home This is puzzling me for two reasons: 1.) df says that /dev/sda1, mounted at /, has a 7.4 gigabyte capacity, of which only 7.0 gigabytes are in use, yet it reports / being 100 percent full; and 2.) I can create files on / so it clearly does have space left. Possibly relevant is that the directory /www is a symbolic link to /home/www, which is on a different partition (/dev/sda3, mounted at /home). Can anyone offer suggestions on what might be going on here? The server appears to be working without issue, but I want to make sure there's not a problem with the partition table, file systems or something else which might result in implosion (or explosion) later.

• Is there a Moria like theme for Visual Studio 2010?

  - by Junior Mayhé

  Is there some cool Moria like theme for Visual Studio 2010? Mine is highlighting gray font with gray background! I just can't configure it on Tools-Options-Environment-Fonts and Colors menu. Visual Studio doesn't seem to show an item for this "highlighting keyword/tag system". You select a variable on variable called myVar, and it highlights all with the same name but with a grayer color and gray background. I just can't read it and can't set it.

• MapReduce job is hung after 1 of 5 reducers completed on single-node environment

  I have only one Data Node on my dev environment on EC2.

• Best way to play wav files in the browser?

  - by Splatzone

  I have no choice but to play wav files directly in the browser (serverside encoding to mp3 isn't an option, unfortunately.) What's the best way to do this? I'd really like to take advantage of the HTML 5 audio tag but my target audience includes many, many teens using IE6. As far as I'm aware flash isn't an option, but speedy playback really is critical. Thanks.
