  • Emacs comment-region in C mode

    - by Kinopiko
    In GNU Emacs, is there a good way to change the comment-region command in C mode from /* This is a comment which extends */ /* over more than one line in C. */ to /* This is a comment which extends over more than one line in C. */ ? I have tried (setq comment-multi-line t) but this does not help. There is a section on multi-line comments in the Emacs manual, but it does not mention anything.

  • How do you clear the focus in javascript?

    - by Andres
    I know this shouldn't be that hard, but I couldn't find the answer on Google. I want to execute a piece of javascript that will clear the focus from whatever element it is on without knowing ahead of time which element the focus is on. It has to work on firefox 2 as well as more modern browsers. Is there a good way to do this?

  • Programmatically measure size and way-order of L1 and L2 caches

    - by osgx
    How can I measure programmatically (not query the OS, but measure) the size and order of associativity of L1 and L2 caches (data caches)? Assumptions about system: It has L1 and L2 cache (may be L3 too, may be cache sharing), It may have a hardware prefetch unit (just like P4+), It has a stable clocksource (tickcounter or good HPET for gettimeofday). There are no assumptions about OS (it can be Linux, Windows, or something non-standard), and we can't use POSIX queries. Language is C. And compiler optimizations may be disabled.

  • FileFinder using SQL

    - by James Morgan
    I was thinking of working on a project while I have some free time and this one looks pretty nice: http://mindprod.com/project/filefinder.html One thing I'm wondering about is that will it really be much faster compared to the regular windows search if I use SQL? I'm planning to use MySQL since it's open source. Also, do I need to be good at databases for this? I have basic knowledge about relational databases and can definitely make some SQL statements. Thanks.

  • What Implementation of Forth to use for Learning Forth

    - by Peter Kofler
    I want to start learning Forth (like in this related article). I see that there are many implementations. I would like to use a ANS 1994 compatible version (if reasonable, but sticking to the standard might be good) small and compact implementation, I don't want a full OS. Windows easy to use, I am new to Forth ;-) Can anybody recommend any particular implementation?

  • JSTree, is it possible to add a handle?

    - by nobosh
    I'm very interested in using JSTree for a Sortable list that allows for nesting. The problem is, in my list items I want things like checkboxes, etc... which isn't possible because the entire list is draggable with JSTREE. Is there a way to add a handler to JSTree so only when the handler is clicked the list is draggable? That would allow me to add all kinds of good stuff in the list that can be interacted with by the user. http://www.jstree.com/ Thanks

  • how a view controller know when it is dismissed or poped out of the navigation controller stack?

    - by Thanh-Cong Vo
    Hi all, My view controller needs to know when it is poped out of the navigation controller stack, so that it can retain itself, wait and release itself later with another notification. I intend to do like that when the view is sent dealloc message: - (void)dealloc { if (self.isPerformingSomeTask) { self.isPopedOut = YES; [self retain]; return; } [super dealloc]; } But I think this is not a good solution? Any idea?

  • Exception Handling in SQl Stored Procedures?

    - by Rishabh Ohri
    Hi All, Adding Exceptional Handling is a good practise, but I have a doubt, In our database we have 10 SPs which are accessed by our data access layer, there is not much logic and the queries are also not big.The purpose of keeping the queries in SPs was to allow paged data to be easily passed to the presentation layer. So, my question is, should error handling be added to the SPs in this scenario when they do not include large complex queries?

  • How can I determine which taskbar application/windows are requesting user attention

    - by Frederic
    I'd like to know how to get a list of the windows requiring user attention from the Windows taskbar. Windows requiring attention appear with a flashing orange color within the Windows taskbar. Un-focused MSN Messenger conversation windows are a good example of this behavior: they turn orange as soon as a remote user sends an instance message. My code targets the Windows 7 platform, but working on older Windows OS would be nice too.

  • Java Annotations in eclipse Tooltip?

    - by reccles
    Is anyone aware of an eclipse plugin that updates the tooltip on hover over a method/class to include annotation information? There a few libraries we are using that have annotated methods and it would be handy if I could hover over the method and see what has been applied. I realize this would only work with annotations that have been retained but that is good enough.

  • Sysadmin 101: How can I figure out why my server crashes and monitor performance?

    - by bflora
    I have a Drupal-powered site that seems to have neverending performance problems. It was butt-slow about 5 months ago. I brought in some guys who installed nginx for anonymous visitors, ajaxified a few queries so they wouldn't fire during page load, and helped me find a few bottlenecks in the code. For about a month, the site was significantly faster, though not "fast" by any stretch of the word. Meanwhile, I'm now shelling out $400/month to Slicehost to host a site that gets less than 5,000/uniques a day. Yes, you read that right. Go Drupal. Recently the site started crashing again and is slow again. I can't afford to hire people to come in, study my code from top to bottom, and make changes that may or may not help anymore. And I can't afford to throw more hardware at the problem. So I need to figure out what the problem is myself. Questions: When apache crashes, is it possible to find out what caused it to crash? There has to be a way, right? If so, how can I do this? Is there software I can use that will tell me which process caused my server to die? (e.g. "Apache crashed because someone visited page X." or "Apache crashed because you were importing too many RSS items from feed X.") There's got to be a way to learn this, right? What's a good, noob-friendly way to monitor my current apache performance? My developer friends tell me to "just use Top, dude," but Top shows me a bunch of numbers without any context. I have no clue what qualifies as a bad number or a good number in Top, or which processes are relevant and which aren't. Are there any noob-friendly server monitoring tools out there? Ideally, I could have a page that would give me a color-coded indicator about how apache is performing and then show me a list of processes or pages that are sucking right now. This way, I could know when performance is bad and then what's causing it to be so bad. Why does PHP memory matter? My apparently has a 30MB memory foot print. Will it run faster if I bring that number down? Thanks for any advice. I spent a year or so trying to boost my advertising income so I could hire a contractor to solve my performance woes. I didn't want to have to learn all this sysadmin voodoo. I'm now resigned to the fact that might not have a choice.

    Being an aspiring Apple developer, I want to get the opinions of the community if it is better to learn C first before moving into Objective-C and ultimately the Cocoa Framework? My gut says learn C, which will give me a good foundation.

  • Java -Xms initial size effects

    - by SyBer
    Hi. What is the benefit of setting the -Xms parameter, and having the initial memory larger for example, then the default calculated one (64 MB in my case, according to Java GC tunning: http://java.sun.com/javase/technologies/hotspot/gc/gc_tuning_6.html#par_gc.ergonomics.default_size)? Also, is there any good to setting both the initial and maximum memories to same size? Thanks.
