  • Sync GIT and ClearCase

    - by Senthil A Kumar
    I am currently working on ClearCase and now migrating to GIT. But we need this migration in a way that all work will be done in GIT and the data will be synced backed to ClearCase stream. We will have the same branch names and stream names in both GIT and CC, so scripting shouldn't be a problem. The problem here is, Can someone suggest which is the best model to sync CC and GIT Have all the Vobs in CC as single repo in GIT, and have the major stream in CC as various branches in GIT. - Single GIT repo (VOBS) and many branches (CC streams). - This takes up less space as VOBs are kept as single repo with many branches. Have important CC branches as independent GIT repositories and each repository having all the CC VOBs. - Many GIT repo for many CC branch - This will take up lots of space as VOBs will be replicated across. Which do you think is the best way to keep it in sync with ClearCase

  • Oracle Hash Cluster Overflow Blocks

    - by Andrew
    When inserting a large number of rows into a single table hash cluster in Oracle, it will fill up the block with any values that hash to that hash-value and then start using overflow blocks. These overflow blocks are listed as chained off the main block, but I can not find detailed information on the way in which they are allocated or chained. When an overflow block is allocated for a hash value, is that block exclusively allocated to that hash value, or are the overflow blocks used as a pool and different hash values can then start using the same overflow block. How is the free space of the chain monitored - in that, as data is continued to be inserted, does it have to traverse the entire chain to find out if it has some free space in the current overflow chain, and then if it finds none, it then chooses to allocate a new block?

  • Enabling full documentation for J2EE in eclipse

    - by maayank
    I'm new to Eclipse and am using it currently to play with J2EE. When using Ctrl+Space for types/functions from the regular Java libraries I get a full description (i.e. general description of the type, what are the arguments of the method for, etc.). However I don't get the same for J2EE types. For example, when using Ctrl+Space on methods of the HttpSession class I get only names like "arg0" or "obj" and no description. Is there some kind of a package I can install to remedy this?

  • Strange error in SpringMVC Application Startup

    - by Euzel Villanueva
    I'm getting a very strange stack trace when trying to load a SpringMVC application and at a lost to why this is occurring. org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter#0': Cannot create inner bean '(inner bean)' of type [org.springframework.http.converter.xml.XmlAwareFormHttpMessageConverter] while setting bean property 'messageConverters' with key [4];

  • ffmpeg screen capture

    - by Mirai
    I wrote this script for some basic screen capture; it gets the window dimensions then uses the ffmpeg binary to record. I suspect there is a better way (maybe with the ffmpeg library), but scripting is what I know and ffmpeg generally works. Any software (other than recordmydesktop), or improvements to the script are welcome. info=`xwininfo -frame` H=`echo "$info" | grep Height | sed -E "s/^.*: ([[:digit:]]+)$/\1/"` W=`echo "$info" | grep Width | sed -E "s/^.*: ([[:digit:]]+)$/\1/"` offset=:0.0+`echo "$info" | grep Corners | sed -E "s/^.*:[[:space:]]+\+([[:digit:]]+\+[[:digit:]]+)[[:space:]]+.+/\1/" | tr + ,` /usr/local/bin/ffmpeg -f x11grab -s ${W}x${H} -r 45 -i $offset -sameq -f avi ~/videos/`date +%Y-%m-%d-%H%M%s`_vid & echo $! > /tmp/$(basename $0)-$USER

  • How to sort in-place using the merge sort algorithm?

    - by eSKay
    I know the question is too open. All I want is someone to tell me how to convert a normal merge sort into an in-place merge sort (or a merge sort with constant extra space overhead). All I can find (on the net) is pages saying "it is too complex" or "out of scope of this text". "The only known ways to merge in-place (without any extra space) are too complex to be reduced to practical program." (from here) Even if it is too complex, can somebody outline the basic concept of how to make the merge sort in-place?

  • Install GRUB on NTFS

    - by karatchov
    I would like to install 2 completely independent instances of Windows XP (no data should be shared) in my computer within 2 different primary partitions. I know that grub can handle booting them correctly, but I have no idea if it's possible to install it and configure it within a 100% NTFS system and without any extra linux partition/distribution.

  • Is xterm the terminal window we open in Ubuntu

    - by blog.adaptivesoftware.biz
    I know this is a very naive question. I was reading somewhere that Linux allows 7 xterm's. However, I can start more than 7 terminal apps from my Ubuntu system (Application - Accessories - Terminal). There is definetely a hole in my knowledge... will help if someone helped me understand the difference between an xterm and the Terminal application in a Linux distribution such as Ubuntu.

  • Doubts in System call mechanism in linux

    - by bala1486
    We transit from ring3 to ring0 using 'int' or the new 'syscall/sysenter' instruction. Does that mean that the page tables and other stuffs that needs to be modified for the kernel is automatically done by the 'int' instruction or the interrupt handler for the 'int 0x80' will do the required stuff and jump to the respective system call. Also when returning from a system call, we again need to go to user space. For this we need to know the instruction address in the user space to continue the user application. Where is that address stored. Does the 'ret' instruction automatically changes the ring from ring3 to ring0 or where/how this ring changing mechanism takes place? Then, i read that changing from ring3 to ring0 is not as costly as changing from ring0 to ring3. Why is this so?? Thanks, Bala

  • Regex-expression with danish characters

    - by timkl
    I'm currently trying to wrap my head around regex, I have a validation snippet that tests an input box against a regex-expression: $.validator.addMethod("customerName", function(value, element){ return (/^[a-zA-Z]*$/).test(value); }, "Some text"); That works well, but when I try to add a space and some special danish characters, it doesn't filter the danish characters, only the space. $.validator.addMethod("customerName", function(value, element){ return (/^[a-zA-Z æøåÆØÅ]*$/).test(value); }, "Some text"); Any ideas to what could be wrong?

  • parsing string off a configuration using strtok in C

    - by Jessica
    in the configuration file i have entries similar to this one: filepath = c:\Program Files\some value Where the path can contain spaces and there are no quotes on that string. I tried parsing this with strtok like: char *option; char *value; value = strtok(line, " ="); strcpy(option, value); value = strtok(NULL, " ="); where line is the line I am reading from the file, option will contain the left side of the equal (filepath) and value will contain the right side (c:\program files\some value). I know, it's poor coding, but I haven't found something better. sorry... In any case, for those options where there's no space in the right side it works great, but in those containing spaces it only return the string until the 1st space: c:\Program. Is there any other way to do this? Code is appreciated. Jessica

  • Pros and cons of ways of storing an unsigned int without an unsigned int data type

    - by fields
    I have values that are 64-bit unsigned ints, and I need to store them in mongodb, which has no unsigned int type. I see three main possibilities for storing them in other field types, and converting on going in and out: Using a signed int is probably easiest and most space efficient, but has the disadvantage that they're not human readable and if someone forgets to do the conversion, some of them will work, which may obscure errors. Raw binary is probably most difficult for inexperienced programmers to deal with, and also suffers from non-human-readability. A string representation is the least space efficient (~40 bytes in unicode vs 8 bytes per field), but then at least all of the possible values will map properly, and for querying only a conversion to string is required instead of a more complicated conversion. I need these values to be available from different platforms, so a single driver-specific solution isn't an option. Any major pros and cons I've missed? Which one would you use?

  • ack (perl?) regexp matching lines where if is the first word

    - by Gauthier
    Hey. I'm finally learning regexps, training with ack. I believe this uses perl regexp. I want to match all lines where the first non-blank characters are if (<word> !, with any number of spaces in between the elements. This is what I came up with: ^[ \t]*if *\(\w+ *! It only nearly worked. ^[ \t]* is wrong, since it matches one or none [space or tab]. What I want is to match anything that may contain only space or tab (or nothing). For example these should not match: // if (asdf != 0) else if (asdf != 1) How can I modify my regexp for that?

  • Variable length Blob in hibernate?

    - by Seth
    I have a byte[] member in one of my persistable classes. Normally, I'd just annotate it with @Lob and @Column(name="foo", size=). In this particular case, however, the length of the byte[] can vary a lot (from ~10KB all the way up to ~100MB). If I annotate the column with a size of 128MB, I feel like I'll be wasting a lot of space for the small and mid-sized objects. Is there a variable length blob type I can use? Will hibernate take care of all of this for me behind the scenes without wasting space? What's the best way to go about this? Thanks!

  • SSL certificate for Oracle Application Server 11g

    - by Easter Sunshine
    I was asked to get an SSL certificate for an "Oracle Application Server 11g" which has a soon-to-expire certificate. Brushing aside the fact that 10g seems to be the newest version, I got a certificate from InCommon, as I usually do without problem (except this is the first time I supplied Oracle Application Server 11g as the software type on the CSR form). On the email containing links to download the certificate, it mentioned: Certificate Details: SSL Type : InCommon SSL Server : OTHER I forwarded the email over to the person responsible for installing it and got a reply that the server type must be Oracle Application Server for the certificate to work (the CN is the same as before). They were unable to install this certificate (no details provided to me) and mentioned they had this issue previously with Thawte when they didn't supply Oracle Application Server as the server type. I don't see any significant difference between the currently installed certificate (working) and the new one I just got signed by InCommon (not working). $ openssl x509 -in sso-current.cer -text shows, with irrelevant information ommitted.

  • Way to get VS 2008 to stop forcing indentation on namespaces?

    - by Earlz
    I've never really been a big fan of the way most editors handle namespaces. They always force you to add an extra pointless level of indentation. For instance, I have a lot of code in a page that I would much rather prefer formatted as namespace mycode{ class myclass{ void function(){ foo(); } void foo(){ bar(); } void bar(){ //code.. } } } and not something like namespace mycode{ class myclass{ void function(){ foo(); } void foo(){ bar(); } void bar(){ //code.. } } } Honestly, I don't really even like the class thing being indented most of the time because I usually only have 1 class per file. And it doesn't look as bad here, but when you get a ton of code and lot of scopes, you can easily have indentation that forces you off the screen, and plus here I just used 2-space tabs and not 4-space as is used by us. Anyway, is there some way to get Visual Studio to stop trying to indent namespaces for me like that?

  • jquery ui modal dialog problems in IE

    - by JohnM2
    I use jquery ui dialog widget. Everything works fine in FF, Opera etc., except IE. The problem is that when dialog is opened in Internet Explorer, some space (not covered with that "modal gray layer") is added at the bottom of the document, and page is scrolled to the bottom. So I don't even see the dialog, I have to scroll up, to see it fully. Anyone had that problems? Any solutions? EDIT: now I see, that this "bottom space" is also added in FireFox, but it doesn't scroll to it like in IE.
