  • What are the Ruby equivalent of Python itertools, esp. combinations/permutations/groupby?

    - by Amadeus
    Python's itertools module provides a lots of goodies with respect to processing an iterable/iterator by use of generators. For example, permutations(range(3)) --> 012 021 102 120 201 210 combinations('ABCD', 2) --> AB AC AD BC BD CD [list(g) for k, g in groupby('AAAABBBCCD')] --> AAAA BBB CC D What are the equivalent in Ruby? By equivalent, I mean fast and memory efficient (Python's itertools module is written in C).

  • How to Instantiate ObjectFrame in VB.NET

    - by Suman
    I am trying to reach methods and properties of ObjectFrame through vb.net. But when I declared this as Dim objOLEObject As ObjectFrame and then trying to instantiate it as ObjOLEObject = New ObjectFrame it shows error like: "429: Retriveing the COM class factory for component with CLSID {3806e95d-e47c-11-cd-8701-00aa003f0f7} failed due to the following error: 80040154" To resolve this we re-installed both MS-Office 2003 and VS-2005, but could not get the solution. Could anyone suggest me how to declare and use this in vb.net? Thanks.

  • Why does the rename() syscall prohibit moving a directory that I can't write to a different director

    - by Daniel Papasian
    I am trying to understand why this design decision was made with the rename() syscall in 4.2BSD. There's nothing I'm trying to solve here, just understand the rationale for the behavior itself. 4.2BSD saw the introduction of the rename() syscall for the purpose of allowing atomic renames/moves of files. From 4.3BSD-Reno/src/sys/ufs/ufs_vnops.c: /* * If ".." must be changed (ie the directory gets a new * parent) then the source directory must not be in the * directory heirarchy above the target, as this would * orphan everything below the source directory. Also * the user must have write permission in the source so * as to be able to change "..". We must repeat the call * to namei, as the parent directory is unlocked by the * call to checkpath(). */ if (oldparent != dp->i_number) newparent = dp->i_number; if (doingdirectory && newparent) { VOP_LOCK(fndp->ni_vp); error = ufs_access(fndp->ni_vp, VWRITE, tndp->ni_cred); VOP_UNLOCK(fndp->ni_vp); So clearly this check was added intentionally. My question is - why? Is this behavior supposed to be intuitive? The effect of this is that one cannot move a directory (located in a directory that one can write) that one cannot write to another directory that one can write to atomically. You can, however, create a new directory, move the links over (assuming one has read access to the directory), and then remove one's write bit on the directory. You just can't do so atomically. % cd /tmp % mkdir stackoverflow-question % cd stackoverflow-question % mkdir directory-1 % mkdir directory-2 % mkdir directory-1/directory-i-cant-write % echo "foo" > directory-1/directory-i-cant-write/contents % chmod 000 directory-1/directory-i-cant-write/contents % chmod 000 directory-1/directory-i-cant-write % mv directory-1/directory-i-cant-write directory-2 mv: rename directory-1/directory-i-cant-write to directory-2/directory-i-cant-write: Permission denied We now have a directory I can't write with contents I can't read that I can't move atomically. I can, however, achieve the same effect non-atomically by changing permissions, making the new directory, using ln to create the new links, and changing permissions. (Left as an exercise to the reader) . and .. are special cased already, so I don't particularly buy that it is intuitive that if I can't write a directory I can't "change .." which is what the source suggests. Is there any reason for this besides it being the perceived correct behavior by the author of the code? Is there anything bad that can happen if we let people atomically move directories (that they can't write) between directories that they can write?

  • Windows repair console, impossible?

    - by Daniel
    I found an old Windows XP SP2 in my -trash- cd can and tried it on a 30 GB FAT32 partition. Installation went fine till the copying operation was completed and XP asked for reboot. After that either it starts over again or throws invalid disk. Starting over is an infinite loop the only way I see is to choose the "Repair console" but I'm not used to a DOS box. Can anyone help me through this harmful installation?

  • How can I query Google Spreadsheets API with a string value?

    - by ColinM
    I am using Zend_Gdata_SpreadsheetsListQuery. In PHP my query is: "confirmation=$confirmation" The problem is that $confirmation = 'AB-CD-EFG-012345'; Apparently the hyphens are causing problems with the query and the exception thrown is: Uncaught exception 'Zend_Gdata_App_HttpException' with message 'Expected response code 200, got 400 Parse error: Invalid token encountered' How can I quote or escape the value to not cause parse errors? Single quotes cause the same error, double quotes don't throw errors but there are no results to match.
