  • nginx not starting at reboot after gitlab installation

    - by Luis Masuelli
    I installed nginx (1.6) in ubuntu server (14.04). After that, I installed gitlab. I didn't realize it came with its own nginx. I uninstalled gitlab later. After installing gitlab, my first nginx began to never start at boot as a service. This means: If I hit sudo netstat -anp I don't see the corresponding entry in 0.0.0.0:80. If I hit sudo nginx -s reload and then sudo netstat -anp I see the corresponding entry I mentioned. I thought I could fixing it by doing: sudo update-rc.d nginx remove sudo update-rc.d nginx defaults After removing gitlab, but it did not help me (i.e. after reboot, nginx does not automatically start). I revised the /etc/init.d/nginx just to see that $DAEMON is still /usr/sbin/nginx. Question: What should I check to see the problem here (or: what could the problem be)? sudo nginx -s reload works with no problems at all.

  • SQL - First row inserted every day for the past X days

    - by okie.floyd
    A tough SQL question (I'm using postgres by the way). I need the first row inserted every day for the past X days. one of my columns is a timestamp, which i hold the time inserted, and another column is the row id. If it's not possible to get the first row inserted every day, i at least need a unique one; a single row for every day for the past x days. Any suggestions? Thanks okie

  • Hibernate3: Self-Referencing Objects

    - by monojohnny
    Need some help on understanding how to do this; I'm going to be running recursive 'find' on a file system and I want to keep the information in a single DB table - with a self-referencing hierarchial structure: This is my DB Table structure I want to populate. DirObject Table: id int NOT NULL, name varchar(255) NOT NULL, parentid int NOT NULL); Here is the proposed Java Class I want to map (Fields only shown): public DirObject { int id; String name; DirObject parent; ... For the 'root' directory was going to use parentid=0; real ids will start at 1, and ideally I want hibernate to autogenerate the ids. Can somebody provide a suggested mapping file for this please; as a secondary question I thought about doing the Java Class like this instead: public DirObject { int id; String name; List<DirObject> subdirs; Could I use the same data model for either of these two methods ? (With a different mapping file of course). --- UPDATE: so I tried the mapping file suggested below (thanks!), repeated here for reference: <hibernate-mapping> <class name="my.proj.DirObject" table="category"> ... <set name="subDirs" lazy="true" inverse="true"> <key column="parentId"/> <one-to-many class="my.proj.DirObject"/> </set> <many-to-one name="parent" class="my.proj.DirObject" column="parentId" cascade="all" /> </class> ...and altered my Java class to have BOTH 'parentid' and 'getSubDirs' [returning a 'HashSet']. This appears to work - thanks, but this is the test code I used to drive this - I think I'm not doing something right here, because I thought Hibernate would take care of saving the subordinate objects in the Set without me having to do this explicitly ? DirObject dirobject=new DirObject(); dirobject.setName("/files"); dirobject.setParent(dirobject); DirObject d1, d2; d1=new DirObject(); d1.setName("subdir1"); d1.setParent(dirobject); d2=new DirObject(); d2.setName("subdir2"); d2.setParent(dirobject); HashSet<DirObject> subdirs=new HashSet<DirObject>(); subdirs.add(d1); subdirs.add(d2); dirobject.setSubdirs(subdirs); session.save(dirobject); session.save(d1); session.save(d2);

  • Performance with timestamp conditions

    - by Tim Whitlock
    Which of the following is faster, or are they equivalent? (grabbing recent most records from a TIMESTAMP COLUMN) SELECT UNIX_TIMESTAMP(`modified`) stamp FROM `some_table` HAVING stamp > 127068799 ORDER BY stamp DESC or SELECT UNIX_TIMESTAMP(`modified`) stamp FROM `some_table` WHERE UNIX_TIMESTAMP(`modified`) > 127068799 ORDER BY `modified` DESC or even another combination?

  • Desktop appliciations are unable to launch my browser in Windows 8

    - by Chevex
    I have a fresh copy of Windows 8 Pro installed from MSDN. I have Google Chrome installed (stable channel) and it is set as my default browser. I even went into Control Panel Default Programs to ensure that Chrome had all its defaults. When other desktop applications try to launch my browser they always fail. For example, while trying to install the Android SDK for Windows the installer accurately detected that I did not have the JDK installed. It provides a friendly button to visit java.oracle.com. When pressing this button, nothing happens at all. You can see that here: http://youtu.be/XXL8GhuWWg0 If it were only that application that was having issues I wouldn't think anything of it but I have been encountering similar issues all over the place. Probably the most irritating one is when visual studio has updates; clicking the update button does nothing. http://www.youtube.com/watch?v=zwd1mn3TId0 You can see in that screencast that Visual Studio is not able to launch the browser no matter what I click. The update button doesn't do anything and neither do the two links in the update's description. Any suggestions? I'm assuming it's a Windows issue since it is happening in multiple applications. UPDATE: Setting IE as the default browser fixes the issue. So it has something to do with it not being able to launch Chrome programmatically. Is it even possible to workaround this bug or do I have to suffer with IE as default for now?

  • Why do updates inside of a SQL transaction still need disk IO?

    - by usr
    In SQL Profiler you can see that very simple updates to a table by primary key take about 10-30ms each. On about every 10th update the write column shows 1, on all other updates it shows 0. This must mean that about every 10th update statement still requires disk IO. I wonder why that is. Would it not be more efficient queue up all IO until the transaction commits?

  • If I create a transient property in the model, isn't this managed by core data then?

    - by mystify
    Just to grok this: If I had a transient property, lets say averagePrice, and I mark that as "transient" in the data modeler: This will not be persistet, and no column will be created in SQLite for that? And: If I make my own NSManagedObject subclass with an averagePrice property, does it make any sense to model that property in the xcdatamodel file? Would it make a difference if I would simply create a property in my subclass and not model that in the entity? (I think: yes, it doesn't matter at all ... but not sure)
