  • CHECK/NOCHECK for Sql Compact Edition

    - by Ryan H
    I am attempting to wipe and repopulate test data on SQL CE. I am getting an error due to FK constraints existing. Typically in Sql2005 I would ALTER TABLE [tablename] CHECK/NOCHECK CONSTRAINT ALL to enable/disable all constraints. From what I could find in my searching, it seems that this might not be supported in CE. Is that true? If so, is there an alternative?

  • Java - is it possible to read a file line by line, stop, and then immediately start reading bytes wh

    - by hatorade
    I'm having an issue trying to parse the ascii part of a file, and once I hit the end tag, IMMEDIATELY start reading in the bytes from that point on. Everything I know in Java to read off a line or a whole word creates a buffer, which ruins any chance of getting the bytes immediately following my stop point. Is the only way to do this read in byte-by-byte, find new-lines, reconstruct everything prior to the new-line, see if it's my end tag, and go from there?

  • How do I stop Mercurial's "hg serve -d" service under Windows?

    - by Joel
    I'm technically savvy but don't have extensive experience with servers/daemons (I'm a Windows guy, so...command lines intimidate me). I started a Mercurial server using the hg serve -d command, and all was well. Now, I want to stop it, and can't find a process to kill. Does anybody know the process name or a relatively simply CLI command to get it done?

  • Fairness: Where can it be better handled?

    - by Srinivas Nayak
    Hi, I would like to share one of my practical experience with multiprogramming here. Yesterday I had written a multiprogram. Modifications to sharable resources were put under critical sections protected by P(mutex) and V(mutex) and those critical section code were put in a common library. The library will be used by concurrent applications (of my own). I had three applications that will use the common code from library and do their stuff independently. my library --------- work_on_shared_resource { P(mutex) get_shared_resource work_with_it V(mutex) } --------- my application ----------- application1 { *[ work_on_shared_resource do_something_else_non_ctitical ] } application2 { *[ work_on_shared_resource do_something_else_non_ctitical ] } application3 { *[ work_on_shared_resource ] } *[...] denote a loop. ------------ I had to run the applications on Linux OS. I had a thought in my mind, hanging over years, that, OS shall schedule all the processes running under him with all fairness. In other words, it will give all the processes, their pie of resource-usage equally well. When first two applications were put to work, they run perfectly well without deadlock. But when the third application started running, always the third one got the resources, but since it is not doing anything in its non-critical region, it gets the shared resource more often when other tasks are doing something else. So the other two applications were found almost totally halted. When the third application got terminated forcefully, the previous two applications resumed their work as before. I think, this is a case of starvation, first two applications had to starve. Now how can we ensure fairness? Now I started believing that OS scheduler is innocent and blind. It depends upon who won the race; he got the largest pie of CPU and resource. Shall we attempt to ensure fairness of resource users in the critical-section code in library? Or shall we leave it up to the applications to ensure fairness by being liberal, not greedy? To my knowledge, adding code to ensure fairness to the common library shall be an overwhelming task. On the other hand, believing on the applications will also never ensure 100% fairness. The application which does a very little task after working with shared resources shall win the race where as the application which does heavy processing after their work with shared resources shall always starve. What is the best practice in this case? Where we ensure fairness and how? Sincerely, Srinivas Nayak

  • How to get distinct results in hibernate with joins and row-based limiting?

    - by Daniel Alexiuc
    I'm trying to implement paging using row-based limiting (for example: setFirstResult(5) and setMaxResults(10)) on a Hibernate Criteria query that has joins to other tables. Understandably, data is getting cut off randomly; and the reason for that is explained here. As a solution, the page suggests using a "second sql select" instead of a join. How can I convert my existing criteria query (which has joins using createAlias()) to use a nested select instead?

  • CCATS needed for non-export iPhone app?

    - by Steve
    I'm getting ready to finally deploy my first iPhone app. The app uses SSL to connect to a REST web service. While reading the docs on deploying the app to the app store, I came across some drivel regarding having to go through a 30 - 60 day government vetting process just to ship an app that simply connects to an HTTPS server. My question is, since this is an export requirement, do apps that are only distributed in the US face this same restriction? Thanks
