• How to Adjust/Change Scrollbar Width

  - by goodan

  Is there a way to temporarily change the scrollbar width in FF or IE while I'm testing some layout code? I remember reading something a while back about this being related to resolution, but it was a while back can't remember the details. Is there a setting in FF or IE to temporarily change scrollbar width?

• Authenticated proxy in Windows command prompt

  - by tlvince

  My Internet access is delivered through an authenticated proxy. This is setup correctly in the "Internet Options" control panel applet and all browsing/GUI apps work fine. For cmd, proxy settings are typically set by exporting http_proxy. The applications I'm trying to use are git and Putty's pscp.exe. I've tried the following syntax to no avail: set http_proxy=http://username:[email protected]:port/ I've also experimented with Netsh.exe and ProxyCfg.exe with no luck. How does one configure an authenticated proxy in the Windows command prompt?

• Yum through http proxy

  - by eodchop

  I have several Fedora 13 servers that have to connect through an http proxy for yum updates. All port 80 traffic has to be routed through this proxy. I have setup the proxy server in the network settings GUI. I can browse the internet just fine. I have also setup my proxy information in /etc/yum.conf as follows: proxy=http:proxy.largecorp.corp/accelerated_pac_base.pac proxy_user=user proxy_password=password I then added the export HTTP_PROXY="http:proxy.largecorp.corp/accelerated_pac_base.pac" to /etc/bashrc and sourced the file. When i run yum update: Loaded plugins:presto, refresh-packagekit Error: Cannot retrieve repository metadata (repomd.xml) fro repository: fedora. Please verify its path and try again. All of the repo urls are the defaults, as this is a fresh install.

• Not able to create a datasource registration with WAMP MysQL 5.0 in DBArtisan

  - by Alf Christophersen

  I try in a test version of DBArtisan to set up a datasource and register both servere as localhost, database to use, my username and password, but, when testing the connection, I get message that connection failed. Hooking up from eg. Delphi and other utilities run nicely. But not DBArtisan, Is MySQL 5.0 not supported yet ?? Or is it WAMP that is the culprit naming the service wampmysqld insted of just mysqld ??

• How can I delete Time Machine files using the commandline

  - by Tim

  I want to delete some files/directories from my Time Machine Partition using rm, but am unable to do so. I'm pretty sure the problem is related to some sort of access control extended attributes on files in the backup, but do not know how to override/disable them in order to get rm to work. An example of the error I'm getting is: % sudo rm -rf Backups.backupdb/MacBook/Latest/MacBook/somedir rm: Backups.backupdb/MacBook/Latest/MacBook/somedir: Directory not empty rm: Backups.backupdb/MacBook/Latest/MacBook/somedir/somefile: Operation not permitted There are a number of reasons I do not want to use either the Time Machine GUI or Finder for this. If possible, I'd like to be able to maintain the extended protection for all other files (I'd like not to disable them globally, unless I can re-enable once I've done my work).

• freebsd dev server on virtualbox over windows

  - by g_kaya

  I need a unixy environment for development purposes. I hate doing things on windows but it is more stable for daily use and I don't have a mac, so I'm having to use windows (7). I want to run freebsd in a virtual machine, configure it to be the localhost server, be able to connect using ssh (within my home-network) and be able to install vbox guest addons. If guest additions aren't the best, I can use solaris or linux flavours. I need no gui. I don't know anything about network stuff, so I need a detailed explanation from vise people here, or a nice doc to read. Edit : To be more specific as requested, I use following on unices: *django 1.4 *apache *python (2.7) *emacs *mysql *probably node.js *bash scripting I use windows to be able to do daily things easily, like connecting to my tablet, browsing and learning java. And I don't want to use linux as my desktop os, beacuse it gets broken a lot, it's annoying to maintain wlan problems and some more.

• Hadoop write directory

  - by FaultyJuggler

  Simple question but reading through documentation and configuration I can't quite seem to figure it out. How do I A) know where hadoop is writing to on the local disk and B) change that For initial testing I setup HDFS on a 20gb linux VM - to it we've added a 500gb networked drive for moving towards prototyping the full system. So now how do I point HDFS at that drive, or do I simply move the home directory/install with some slight change in setup and restart the process?

• How can I re-create Microsoft Cluster Service resource groups on a different cluster?

  - by PersonalNexus

  I use Microsoft Cluster Service on a cluster of Windows Server 2003 machines containing several dozen resource groups. In the process of migrating to newer hardware, I would like move resources to the new machines on resource group at a time spread out over a few days to ease the migration and minimize risk. I was wondering of there was a smarter way to do this than manually re-creating resources on the new and then deleting them on the old cluster? The cluster has already been set up properly, the only missing is the resource groups and the resources they contain (IP, network names, services...). I have looked through the options of the cluster admin GUI and cluster.exe's commandline options, but haven't found anything like an import/export feature to copy over the configuration of a resource or entire resource group. Does something like this exist?

• Simple prolog program. Getting error: >/2: Arguments are not sufficiently instantiated

  - by user1279812

  I made a prolog program posAt(List1,P,List2) that tests whether the element at position P of List1 and List2 are equal: posAt([X|Z],1,[Y|W]) :- X=Y. posAt([Z|X],K,[W|Y]) :- K1, Kr is K - 1, posAt(X,Kr,Y). When testing: ?- posAt([1,2,3],X,[a,2,b]). I expected an output of X=2 but instead I got the following error: ERROR: /2: Arguments are not sufficiently instantiated Why am I getting this error?

• Move and clone VirtualBox machines with filesystem commands

  - by mit

  I know of 2 ways to clone a VirtualBox machine on a linux host, one is by using the VirtualBox gui and exporting and re-importing as Appliance (in the file menu of VirtualBox). The other is by cloning only the virtual disk containers: VBoxManage clonevdi source.vdi target.vdi (Taken from http://forums.virtualbox.org/viewtopic.php?p=853#p858 ) I would have to create a new VM afterwards and use the cloned virtual disk. Is there a way I can just copy a virtual disk and the and do the rest by hand? I'd have to manually edit the ~/VirtualBox/VirtualBox.xml and insert a new disk and a new machine: Can I just make up UUIDs or how would this work? I would very much prefer this hardcore method of doing things as it allows me to freely and rapdily backup, restore, move or clone machines. Or ist there a better way to do this?

• Sharing files between centOS on virtualbox and windows 7 as the host

  - by Wasswa Samuel

  I have centOS 5.5 installed on virtual box it has no GUI so every thing is command based. I want to make a folder in centOS which i can share with my windows 7 host OS such that i can send files to and fro seamlessly. I am new to linux and i managed to install samba. I looked up some tips on net but i ended up getting confused and none of them worked. Can someone explain to me how i can do this in a straight forward way from how i can configure samba to how i can mount the folder such that it can be seen on the host operating system. I am completely lost.please help.

• Black screen with cursor after BIOS screen

  - by Radio

  Here is a weird one, Got computer with Windows XP. It's getting stuck on a black screen with cursor blinking. What did I do: - Boot from installation CD (recovery option - command line): chkdsk C: /R copy D:\i386\ntdetect.com c:\ copy D:\i386\ntldr c:\ fixmbr fixboot Chkdsk showed 0 bad sectors and no problems during scan. dir on C:\ shows all directories and files in place (Windows, Program Files, Documents and Settings). BIOS shows correct boot drive. Still does not boot. Not sure what to think of. Please help. UPDATE: Just performed these steps: Backed up current disk C: (without MBR) using True Image to external hard drive Ran Windows XP clean installation with deleting all partitions and creating new one. Hard drive booted fine into Windows GUI installation!!! Then: I interrupted installation. Booted from True Image recovery CD and restored archive of disk C to an new partition. Same issue with black screen.

• I never really understood: what is Application Binary Interface (ABI)?

  - by claws

  I never clearly understood what is an ABI. I'm sorry for such a lengthy question. I just want to clearly understand things. Please don't point me to wiki article, If could understand it, I wouldn't be here posting such a lengthy post. This is my mindset about different interfaces: TV remote is an interface between user and TV. It is an existing entity but useless (doesn't provide any functionality) by itself. All the functionality for each of those buttons on the remote is implemented in the Television set. Interface: It is a "existing entity" layer between the functionality and consumer of that functionality. An, interface by itself is doesn't do anything. It just invokes the functionality lying behind. Now depending on who the user is there are different type of interfaces. Command Line Interface(CLI) commands are the existing entities, consumer is the user and functionality lies behind. functionality: my software functionality which solves some purpose to which we are describing this interface. existing entities: commands consumer: user Graphical User Interface(GUI) window,buttons etc.. are the existing entities, again consumer is the user and functionality lies behind. functionality: my software functionality which solves some purpose to which we are describing this interface. existing entities: window,buttons etc.. consumer: user Application Programming Interface(API) functions or to be more correct, interfaces (in interfaced based programming) are the existing entities, consumer here is another program not a user. and again functionality lies behind this layer. functionality: my software functionality which solves some purpose to which we are describing this interface. existing entities: functions, Interfaces(array of functions). consumer: another program/application. Application Binary Interface (ABI) Here is my problem starts. functionality: ??? existing entities: ??? consumer: ??? I've wrote few softwares in different languages and provided different kind of interfaces (CLI, GUI, API) but I'm not sure, if I ever, provided any ABI. http://en.wikipedia.org/wiki/Application_binary_interface says: ABIs cover details such as data type, size, and alignment; the calling convention, which controls how functions' arguments are passed and return values retrieved; the system call numbers and how an application should make system calls to the operating system; Other ABIs standardize details such as the C++ name mangling,[2] . exception propagation,[3] and calling convention between compilers on the same platform, but do not require cross-platform compatibility. Who needs these details? Please don't say, OS. I know assembly programming. I know how linking & loading works. I know what exactly happens inside. Where did C++ name mangling come in between? I thought we are talking at the binary level. Where did languages come in between? anyway, I've downloaded the [PDF] System V Application Binary Interface Edition 4.1 (1997-03-18) to see what exactly it contains. Well, most of it didn't make any sense. Why does it contain 2 chapters (4th & 5th) which describe the ELF file format.Infact, these are the only 2 significant chapters that specification. Rest of all the chapters "Processor Specific". Anyway, I thought that it is completely different topic. Please don't say that ELF file format specs are the ABI. It doesn't qualify to be Interface according to the definition. I know, since we are talking at such low level it must be very specific. But I'm not sure how is it "Instruction Set Architecture(ISA)" specific? Where can I find MS Window's ABI? So, these are the major queries that are bugging me.

• How do I set a static bool in another app domain?

  - by Martin

  How do I programatically set the value of a static boolean in another app domain? I'm testing an application where I need to change a bool value. Problem is that the bool value exists as a static instance on a type hosted in another app domain. (I'm doing this for test purposes, it won't be used in production code)

• Preview for create/edit content doesn't work

  - by Snazzy

  Hi! I'm configuring a DRUPAL site web (that it was previously created) and I'm testing the diferent options. When I create a new content or edit a old content and change anything and then I click on 'Preview' doesn't appear the recent changes (just appear the old values), I have to save it before. NOTE: I do the accions as ROOT (it not a privilege problem). Anyone knows what is happened?

• Double reversals on technology decisions

  - by Kev

  Have you ever gone through a painful switch from one technology to another, only to switch back later in a project's lifetime? Was it because the technologies evolved differently than you expected, or because of something you didn't understand about them in the first place, or because they didn't fly when it came to beta testing or production? Did you regret the switch back too?

• Backup software for Ubuntu - which one?

  - by Industrial

  Hi everybody, I have spent some time testing out different backup solutions for my small home office during the last weeks, but still haven't found anything that have been working out too well yet. We can definitely work with a non-GUI script if that's what it takes, if only the requirements are fulfilled: Upload to Amazon S3 Europe. We get unbelievable slow uploading speed to US, so uploading 400+ GB of data will not be happening anytime this year... Incremental backups - only changed files shall be uploaded or we will have a big bill from Amazon in the end of each month.. Files should not be uploaded in one big per-folder archive. This is not efficient at all, since if we change one file in a subfolder, a huge two-digit GB sized file would have to be uploaded during next backup. Not good for economy again, or traffic overhead on our internet connection. What options are available to us? Thanks!

• Make emacs aware of files externally moved/renamed on Mac os x

  - by Gyom

  I've been using mac os x for several years, and I realize that I've now gotten used to all applications transparently "following" files as I rename or move them (either via mv on the console or within the Finder's GUI), and emacs is pretty much the only program that does not. This is a shame though, because most of my time in front a screen is actually spent in front of emacs :-) Would anyone have any ideas or pointers about what measures I could take to get that behaviour in emacs ? (yes I know this is "impossible" to acheive in general, but when I just rename a simple file, or move it to a directory nearby, it's a shame I have to close/reopen it for emacs to notice. oh and no, I'm not going to use 'dired' as a file manager :-)

• recommendations for disk -> usb backup software

  - by TWood

  Recently I lost a tape drive and rather than repair the unit I decided that backups to usb external drives would be cheaper. In the past I used NTBackup and figured that the new server 2008 R2 backup wbadmin utility would be able to meet my needs. It does not. I am looking for recommendations for another utility that i can use. My requirements are: -backup local disk in addition to files on a network share -scheduled task integration (or some gui options to manage schedule) -non-incremental backup Basically I could do this all with WBAdmin if it just supported network shares. I saw some links that described attaching a vhd pointed to a network share but I am trying to avoid hacks like that. If i'm going to do all that trouble I'd just as well manually copy the directories over myself. If anyone has any software suggestions that might make this task easier for me let me know please. I am considering BackupAssist but can only find a few reviews here and there for it.

• grails mockFor closure wierdness

  - by hvgotcodes

  Right, so when I set up my mock using the testing plugin's mockFor method, I expect a method that returns null. If I do myControl.demand.theMethod {return null} in the debugger, the value that I set the 'theMethod' call result to is some closure in the debugger. If I do myControl.demand.theMethod {->return null} the value is null, as expected. I dont understand the difference....

• Zend Framework in a subfolder, but images taken from site root

  - by Pentium10

  I have a dev project setup in a subfolder on my testing machine and it must stay there. However all the Zend frameworks views are linked to server root. CSS are linked like: <link type="text/css" href="<?php echo $this->baseUrl('/css/frontend.css') ?>" rel="Stylesheet" /> Which must be stayed this way, but it should link to localhost/a/b/c/prj1/css/frontend.css How can I setup a global subdirectory for this?
