• OOP - Composition, Components and Composites Example?

  - by coder3

  I've been reading a bit about OOP in relation to Composition, Components and Composites. I believe I understand the fundamental principle (not sure). Can some one please provide a code example of a person or car (both have many properties) using Composition, Components and Composites. I think seeing it in code would clear up the confusion I have regarding this pattern. Preferably in Java or PHP - many thanks!

• When clientTransferProhibited is off to transfer a domain name, couldn't the name be stolen?

  - by Cedric Martin

  I'd like to transfer a domain from one registrar (Key-systems) to another registrar (OVH). I don't really understand the procedure and I'm a bit confused... I read everywhere that clientTransferProhibited prevents people from stealing your domain name. Now apparently during the course of transferring my domain from Key-systems to OVH, I'll to change clientTransferProhibited so that the transfer is allowed. Wouldn't my domain then become "stealable" during some amount of time? (a few hours / days / week)

• [New England] SQL Saturday 71 - April 2 - Boston Area

  - by Adam Machanic

  April in the Boston area means many things. The Boston Marathon, the beginning of baseball season, and -- hopefully -- a bit of a respite from the ridiculously cold and snowy winter we've been having. This April will mean one more thing: A full-day, free SQL Server event featuring 30 top-notch sessions . SQL Saturday 71 will be the third full-day event in the area in as many years, and is shaping up to be the best yet. For the past several months I've been working and planning in conjunction with...(read more)

• Has any hobbyist attempted to make a simple VGA-graphics based operating system in machine code?

  - by Bigyellow Bastion

  I mean real bare bones, bare machine here(no Linux kernel, pre-existing kernel, or any bootloader). I mean honestly write the bootloading software in direct microarchitecture-specific machine opcode, host the operating system, interrupts, I/O, services, and graphical software and all hardware interaction, computation, and design entirely in binary. I know this is quite the leap here, but I was thinking to practice first in x86 assembly (not binary) 16-bit style. Any ideas?

• DotNetNuke 6 beta released

  - by Chris Hammond

  DotNetNuke 6 is coming, DotNetNuke 6 is coming! That’s right, we’re getting close, close enough that we had our first “beta” for DNN6 today. While we’ve had a couple of CTP (community technology preview) releases, the beta today has quite a bit of things wrapped up and addressed. There are a number of new things coming in DotNetNuke 6, and rather than try to explain them all I’ll point you to Joe Brinkman’s blog post from this morning . The biggest thing is that most of the Admin and Module settings...(read more)

• Map caps-lock key to middle mouse click

  - by Stefano Palazzo

  Since I rarely use caps-lock, I'd like to map the key to a middle mouse click instead. I would also like to map Alt+Caps Lock to the original function of the caps lock key, should I ever need it. I can map any keyboard shortcut to xdotool click 2, but the Gnome Keyboard Shortcuts dialog won't let me assign a command to the caps-lock key, even with modifiers. I know this is a bit of a strange undertaking; How would I go about doing it?

• PowerShell - grabbing values out of the registry and running them

  - by Rob Farley

  So I closed an application that runs when Windows starts up, but it doesn’t have a Start Menu entry, and I was trying to find it. Ok, I could’ve run regedit.exe, navigated through the tree and found the list of things that run when Windows starts up, but I thought I’d use PowerShell instead. PowerShell presents the registry as if it’s a volume on a disk, and you can navigate around it using commands like cd and dir. It wasn’t hard to find the folder I knew I was after – tab completion (starting the word and then hitting the Tab key) was a friend here. But unfortunately dir doesn’t list values, only subkeys (which look like folders). PS C:\Windows\system32> dir HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Run PS C:\Windows\system32> Instead, I needed to use Get-Item to fetch the ‘Run’ key, and use its Property property. This listed the values in there for me, as an array of strings (I could work this out using Get-Member). PS C:\Windows\system32> (Get-Item HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Run).Property QuickSet SynTPEnh Zune Launcher PS C:\Windows\system32> Ok, so the thing I wanted wasn’t in there (an app called PureText, whicih lets me Paste As Text using Windows+V). That’s ok – a simple change to use HKCU instead of HKLM (Current User instead of Local Machine), and I found it. Now to fetch the details of the application itself, using the RegistryKey method GetValue PS C:\Windows\system32> (Get-Item HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Run).GetValue('PureText') "C:\Users\Rob\Utilities\PureText.exe" PS C:\Windows\system32> And finally, surrounding it in a bit of code to execute that command. That needs an ampersand and the Invoke-Expression cmdlet. PS C:\Windows\system32> '& ' + (Get-Item HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Run).GetValue('PureText') | Invoke-Expression A simple bit of exploring PowerShell which will makes for a much easier way of finding and running those apps which start with Windows.

• How to fix 'grub error file not found' when installing 12.04?

  - by Tomasz Grabowski

  i'm trying to install Ubuntu. I don't know if it is important, but i'm trying to install it on external HDD. In the end i have external bootable HDD which only displays: error: file not found grub recovery> From the beginning: I've downloaded ubuntu-12.04-desktop-i386.iso I've used LiLi USB Creator (LinuxLive) to create bootable pendrive from that image I've bootet from it, it works I've clicked "Try ubuntu", it works too. I've used GParted to look over drivers (disks) My primary embedded disk is seen as /dev/sda My attached external disk as /dev/sdb My PenDrive as /dev/sdc I've created partitions on /dev/sdb Fist partition for system (over 200GiB) Second was there already (it's xsf, and i don't want to touch it :P) Third is extended partition, with 1 locital partiton (10GiB) for swap I've started installation i've choose "somethin else" in ... i belive secound screeb then is selected /dev/sdb as boot disk for first partiton of /dev/sdb i set i want ext3 file system, i've check "formattin" checkbox, and mount path set to "/" firs logical partiton set as swap partition After installation finished, i restarted my computer. When i boot from my primary disc it's work ok, my previous operating system - vista - works ok. When i set my BIOS to boot from my external disc, i only get that message: error: file not found grub recovery> I've try to reinstall it, but didn't help... In desperation, i've try to read a bit about that "grub recovery" command-line and experiment a bit... I'm not sure if this has had any point, or if it give you some information (notice, that i don't know what i'm doing :P ) when i've type command: insmod (hd1,1)/boot/grub/linux.mod i've get message: unknown filesystem the same with: insmod (hd1,msdos1)/boot/grub/linux.mod the same with: insmod ext3 but i get no message after command: insmod ext2 ... notice that i really don't know what this command exactly do, but than i thought that maybe if i reinstall ubuntu with ext2 filesystem, it will work. I've done that, but symptoms are the same. I've go back to that Live version of ubuntu, filesystem and basics directories seems to be present on /dev/sdb1 ... i'm completely unfamiliar with GRUB. I'm also don't know which wersion of GRUB it is, i hope there is only one version on ubuntu-12.04-desktop-i386.iso Any help? Thax

• Left mouse button not working in Xubuntu session

  - by giodamelio

  I recent changed from Ubuntu to Xubuntu 12.04. The install worked great for a few days, but suddenly the left mouse button stopped working. The right click and scroll bars work fine. After a bit of experimenting I discovered that the problem only happens when I set the session to Xubuntu at login. The mouse also works fine in my dual-booted Windows vista. What could make my mouse stop working like that?

• The Long Tail Keyword Phrase Phenomenon

  There's been much conversation and debate over whether to use short tail or long tail keyword phrases when working optimizing your articles and websites. I think a bit of both may be in order. Well let's first distinguish the difference and then we can talk about how we can apply them to our articles and/or website meta tags.

• How to compile deskew plugin for Gimp?

  - by mtone

  I'm interesting in using this Deskew plugin which appears somewhat old, with broken links in the gimp registry. https://github.com/prokoudine/gimp-deskew-plugin How do I go about installing it on Ubuntu 64-bit 12.10 running Gimp 2.8? I can't figure what I have to "configure" or "make" to compile the plugin. I understand the end result should be placed Noob-level: I know how to get around in a terminal, but that's about it. Thanks!

• What does it take to successfully run a URL shortener service [on hold]

  - by MxyL

  What are the costs (technology wise) for running a URL shortener service such as bit.ly or anonym.to? For example, if I decided to use an inexpensive shared hosting with "unlimited" bandwidth, would that be feasible? Or would I need a dedicated hosting? I found this question: I want to run a URL shortener for my own usage, what do I need to do?, which makes it easy to set it up, but I'm not too clear what kind of things I need to consider.

• iTorque for a simple arcade game

  - by Herfus

  I have a basic understanding of programming, but I am no programmer. I've had a couple of a semesters with java programming, so we're talking pretty basic here. I have some scripting experience with game editors where I've created a few (simple) encounters, boss AI, abilities, events and so on. I've mostly done level design with UDK, Source and several other toolsets for a few years now, but I'd like to divert some of the focus to iphone-development. I've participated in a few development projects (source, udk, daot) where I've had a variety of roles (yet never beyond simple scripting). I have just finished prototyping an Iphone game (using game maker) and begun a bit more precise planning on what I'll have to do for the real version. The game is fairly simple, perhaps the best comparison in scope and complexity would be Doodlejump for iPhone. The reason I created the prototype was not just to answer a few questions about the gameplay, but to get some insight into what kind of problems I might face when trying to develop the real thing. I've been looking for engines that I can use for this. iTorque looks, so far, like the best option with a scripting language and WYSIWYG-editor. However the price is fairly steep and I'd like to prepare myself as much as possible before jumping into this, which is why I'm going to ask a few questions here. What kind of difficulties do you think I might run into, considering what you've read so far? Not just with torque, but development in general. I'm making this question mostly to have someone to reality check me. I usually achieve to do what I'm trying to do with scripting, but something tells me there's a very big difference between scripting an AI or an event and creating game logic. Will it be too much of a leap? Just how simple is it to use the Torque scripting language? Obviously I don't expect to be prepared, I expect it to be a learning process. However, I'd still like to be at least a bit confident on the time I'll have to dedicate to this first.

• the limit of pageviews per month in Google Analytics

  - by crmpicco

  I have been looking around to try and find some confirmation and clarity on the limit of pageviews that Google allow per month for a Google Analytics account. I have read that the limit of hits per month is 10,000,000, and the limit of pageviews is 5,000,000. Putting 2 and 2 together I am thinking this is to allow the other 5,000,000 for events and social clicks and the like? Google's documentation states 5m, but the hits/pageviews is a bit of a grey area as i've read suggestions that the limit can be considered as 10m

• I'm blogging again, and about time too

  - by fatherjack

  No, seriously, this one is about time. I recently had an issue in a work database where a query was giving random results, sometimes the query would return a row and other times it wouldn't. There was quite a bit of work distilling the query down to find the reason for this and I'll try to explain by demonstrating what was happening by using some sample data in a table with rather a contrived use case. Let's assume we have a table that is designed to have a start and end date for something, maybe...(read more)

• Title of person reporting to CEO responsible for strategy and projects [closed]

  - by user64134

  Case in point: What is the title of the person reporting directly to the CEO and/or CTO, responsible for the overall technical strategy and the overall responsibility for all projects and programs among multiple teams (being led by team leads) in a tech company I'm thinking that it is a mix of a staff and line position - making chief architect being too advisory and not matching the project/program part and VP of engineering a bit too high level?
