• Sharing Files between Ubuntu 14.04 and Windows 8

  - by Matinn

  I have Ubuntu and Windows 8 installed on one System. I am trying to share files between these two operating systems using an NTFS Partition wich was created by Windows. I don't have trouble accessing the data on this partition from Ubuntu, however if i create a file in Ubuntu, this file doesn't show up when I boot into Windows. Does anyone know how to do this. From what I have read file sharing should work without installing any additional Software, as I am not trying to access the Linux ext4 Partition from Windows.

• Ruby - when to use instance variables vs parameters between methods?

  - by Michael Durrant

  I'm writing several methods that call other methods. To pass the information I have a couple of choices: Pass the information as parameters Set instance variables so that other methods can access them When should I choose one option over the other? It seems that the first option is good as it is very specific about what is being passed. the downside seems to be that a lot of values are being passed around. The second method doesn't require passing all the values around but seems to lead to a lot of magic where methods set instance variables 'somewhere' Should I always be very explicit about gets passed to other methods in the class? Are there exceptions so this?

• How To Remote Control Your Home Computer From Anywhere With VNC

  - by Chris Hoffman

  VNC allows you to remotely access a computer and use its desktop, either over the Internet or from another room in your house. Windows includes a Remote Desktop feature, but it’s only available in Professional editions of Windows. Some people may prefer TeamViewer or another service instead, but VNC allows you to install and manage your own server without using a centralized service. VNC clients and servers are available for all platforms, but we’ll be covering Windows here.

• Problems with No-IP redirecting

  - by user171156

  I am setting up a webserver on my ubuntu desktop 13.04, everything is working fine except; When trying to access the server through the external host using no-ip, it gives the original index created by apache on setup. While when I try to connect to the server via my real IP address from externally, it goes to the correct index. I have been trying to figure out what the issue is on this problem as nothing is working because of that bad redirect, I'm wondering if anyone of you could help me out, or advise me in the right path. Thank you very much! PS; If more info needed I'll provide, but this should explain it all.

• Advice Required Regarding Creating a Self Learning, Self Organizing Programming Team....

  - by tGilani

  Hello I'm a senior student at my university and chairperson of IEEE Student Branch there. Recently I was thinking of some idea to acquaint students with the professional environment, how software is produced in the industry and get a practical experience.. Obviously trips to software houses are not enough and we cannot provide this many internships. So the idea of simulating a software house within the university popped in. Resources at my disposal are students with their own laptops, university UPS and lan network with internet access, and a reasonably sized room with a whiteboard and three hours free time daily.. :) However, I have absolutely no idea where to begin with. Milestones or whatever it may be called, are Requirements Document generation, sharing of resources, delegation of tasks, version controlling etc... I'd really appreciate some advice, programming tools (for JAVA), communication tools etc and other things used in a decent software house... Technologies to be targeted shall be random possibly starting with J2EE Spring Hibernate and Later Visual Programming in .NET C# and ASP.NET MVC as well as Android or iPhone development....

• Intro to Sessions in ASP.Net

  Sessions are used to pass the value from one page to another with no effort from the user. With a session, if the user inputs values on the original page and you need to access them on another page, you can retrieve the values stored in the session without making the user submit those values again. Sessions are important to any user-related authentication (if you're using the https protocol), user-related validation and customization of visitor experiences in your website. This tutorial will use Visual Basic to illustrate ASP.NET sessions, though the code can be converted to equivalent C# code...

• Sharing a mounted Truecrypt volume via Samba

  - by user10492

  Been banging my head against the wall on this one for a while. I have an encrypted (via truecrypt) partition on a drive. In windows, I mount it locally and share it on my local network. I'm trying to do the same in Ubuntu 10.10 but am running into permission issues. The tc volume has funny permissions and I just can't seem to figure out a way to access it (unsecurely of course) over my network. Other non-tc volume shares work just fine. To recap, I mount a truecrypt volume in Ubuntu and set up a samba share as normal. The share shows up on my local network but accessing it gives 'permission denied'. Mounting as a network drive using a password does not seem to work either. Any insight would be greatly appreciated.

• Installing Solaris Studio 12.2?

  - by KronoS

  I'm having a dickens of a time installing Solaris Studio 12.2 on Ubuntu 10.04. I found this guide, however using the alien option isn't finding the correct files. I'm not exactly sure on the syntax of alien, its kinda alien to me. (sorry for the bad pun) Also, when I download the tar file, and extract it, there are errors everytime saying things like: "operation not permitted" cannot creat symlink to '../prod/bin/cc': Operation not permitted I've extracted with super user access, but to no avail. Any success from anyone else?

• Hiding images in folder without renaming or moving the files

  - by Marcus

  I'm dual booting Ubuntu with Windows and I have all my music on a separate harddrive. In Windows the album art is hidden by default but when I access the folder in Ubuntu there is two album artwork files for every mp3, one small and one large. I would like to hide those images without having to rename them with a dot before or moving them to some other folder becuase then the album artwork would dissapear in Windows. Is there a way to make a .hidden file which hides all images or any other way which hides all images in nautilus?

• Why setter method when getter method enough in PHP OOP

  - by phphunger

  I am practicing OOP with PHP, and I am struck at setter and getter methods. I can directly access the class properties and methods with getter method then what's the use of setter method? See my example. <?php class MyClass{ public $classVar = "Its a class variable"; public function Getter(){ return $this -> classVar; } } $obj = new MyClass; echo $obj -> Getter(); ?>

• Where do I set my SPF record?

  - by Misha

  Many years ago we purchased a domain from Yahoo. Now our website is hosted on Amazon EC2. The output of an SPF checking tool (http://www.kitterman.com/getspf2.py) says SPF records are primarily published in DNS as TXT records. The TXT records found for your domain are: i=182&m=bizmail-mx2-p9 SPF records should also be published in DNS as type SPF records. No type SPF records found. Checking to see if there is a valid SPF record. No valid SPF record found of either type TXT or type SPF. Where do I get access to these values? Can somebody speculate, where can I find an interface, or a configuration file to fill in the missing fields?

• Fake RAID (dmraid) not seeing new SATA drives

  - by rausch

  I have three drives in my machine, one SSD with 32GB and two 1TB drives, attached to an Intel 82801JI (ICH10) SATA AHCI Controller. The problem is, that I can access only one of the 1TB drives when the other one is not plugged in. When it is plugged in I see the drives as sda and sdb, but there seem to be no partitions. Looking at these drives with cfdisk, the partitions are there, though. Both of the 1TB drives are carrying a partition, being part of a software RAID1, created with mdadm. Before I threw the SSD into the mix, the other two have been working fine. Any hints?

• Would security be comprimised if I install a gui (e.g. zPanel) for LAMP?

  - by Kirk

  I am an Ubuntu/Linux noob. There are many questions I have regarding the use of my system as a server. First and foremost is security. I want to install a simple GUI (zPanel appears the most user friendly) that will allow others to log into the server and database with ease, similar to a hosting service, though my intent is for the development of one site. Upon looking at the instructions of numerous GUI's, they require installation as root. This makes me uneasy, as my thoughts spiral to the possibilities of the developers creating the elusive 'back-door', thereby giving them root access to my entire system. Am I just being paranoid or is that theoretically possible? If it is possible, what steps are necessary to ensure security?

• building bittorrent client from scratch

  - by Bill

  I'm new to programming. I find reading introductory programming books boring. I think these doesn't teach enough of the problem solving skills that I need. So I decided to build a bitTorrent client. I think I understand to some point how the protocol works. I have also downloaded the source code of deluge bittorrent client. I have access to python documentation too. I need to know if there are some resources available that can help me build a bitTorrent client that are more detailed than the wikipedia article here: http://en.wikipedia.org/wiki/BitTorrent

• Video works with 'Try me' but not after install. What is the difference? U12.04LTS,

  - by HarveyP

  My hard drive got corrupted so I did a reinstall. Tested Youtube in FF during 'try me' and it worked - jerky, but it worked. Instal without all the updates (576 outstanding now) in order to get ff installed as per the demo - to no avail. In 'try me' mode ff NEVER crashed! After install ff crashed whilst I was typing in 'youtube' in the address field. When I finally got to youtube - no video. What is the difference between ff in try me and ff after install? Off to try some selected updates now to see if I can see it for myself. In previous installation I had several profiles and aliased ff with -safe-mode switch to simplify startup of most stable ff. Also found that ff startup in graphic mode worked better (but still without video) with all of the extensions disabled and all of the plugins set to "ask" and always denied ... I have SiS graphic card in SiS Motherboard for XP and ancient Hyundai ImageQuest QV770 monitor. I have Ubuntu 12.04.01 LTS 1 day after install with only the immediate upgrades requested to language pack (English UK). Using FR Alternative keyboard. Connected with domestic wifi network from Orange (FT) I really want to use Skype, but won't bother installing it (again) without video as I can do my sms on FB - whilst ff is not crashed ... Update ... Is something overflowing? I have just had to reboot in order to get ff to restart in any way shape or form - restart on crash form generates new crash form, etc. It was however a good half hour before it crashed so some improvement over conditions before disk corruption. I have now installed all of the critical updates (332 recommended updates still outstanding) which included some relating to ff. Still no video. Still crashing - especially when on Grepolis website. Since the re-install I have had a lovely 1024x768 screen, but after last ff crash and reboot I got a message about 'low graphics mode' and 'setting things myself'. I was not sufficiently tuned in at the time to take proper note - I have no doubt I shall see it again and shall report accordingly. I still have only laptop options for my screen and do not know how to rectify this. Spent a few days with ubuntu on a different, newer machine which has now suffered a graphics breakdown. Returned to this old one again, but with new flat screen Monitor. Found SIS drivers for my graphics BUT it is intended for Red Hat 7.2. I chose this over the version for 7.0 because I thought what the hell, I might not be able to do anything with either of them but this is the later one ... The file will not open with software manager - found a similar problem on Overclock but it has not helped me to install this driver. File name is sis_drv.o-410 and it is currently idling away in my Downloads folder ... I have tried the solution offered on another sis problem, but this shows that my xserver-xorg-video-sis driver is up to date. I am now at a loss as to how to proceed if I can't install the latest sis driver from sis ... Does nobody know how FF changes from "try-me" to "installed"? Any time I MUST have video I reboot from the disk again, but this is tedious! Also one of the things I mock most about MS is the constant rebooting ... UPDATE 10/6/2014 I have installed chromium-browser - worse, crashes even more often than ff.I have installed epiphany - better; Video works but not the associated soundtrack.FireFox is version 14.01 in 'try me' and version 29.0 from my install. Would it be useful to try to downgrade FireFox in order to get video?

• Getting data from a webpage in a stable and efficient way

  - by Mike Heremans

  Recently I've learned that using a regex to parse the HTML of a website to get the data you need isn't the best course of action. So my question is simple: What then, is the best / most efficient and a generally stable way to get this data? I should note that: There are no API's There is no other source where I can get the data from (no databases, feeds and such) There is no access to the source files. (Data from public websites) Let's say the data is normal text, displayed in a table in a html page I'm currently using python for my project but a language independent solution/tips would be nice. As a side question: How would you go about it when the webpage is constructed by Ajax calls?

• How to proxy with apache site from same domain but another port as a subfolder?

  - by myWallJSON

  So I have a problem - I have my main site on apache web server on debian on port 80; I develop a web server (in some C++ or C#) and it currently runs on port 6666. But some people are living under firewalls and can access only port 80. I wonder if it is possible via apache map all requests to say mysite.com:80/6666/url as if they were to mysite.com:6666/url, not map via redirection, but really make apache stream content from my site to user as if it were in some folder?

• Bit copy of encrypted home and other partitions

  - by Mka

  My laptop is overheating so I need to save all my files before I format the hard drive. I learned how to copy dev/sdX using dd command. However, I am not sure what to copy. Picture from GParted here: http://is.muni.cz/www/256590/fig.png should I copy sda5 and sda6 only? Or sda2 and sda1? I do not need to use these data on another disk, I just want to be able to access them - therefore I want to put them on external hard drive. And last question - how I will then mount my encrypted home? Will it work? Thanks a lot!

• AdventueWorks Design Patterns Project - Part 1

  - by RonGarlit

  This is the presentation I did tonight at PHILLYNJ.NET.  It is the first in a multi-part of a series on the Applied Design Patterns.   The solution files are working code with design pattern notes in the comment blocks. After the overview and higher level discussions on Enterprise Design Patterns I reviewed the low level Database Access Library of code.  With walk-throughs of the the code and unint test. After that we went through the ProductPhotoConsoleTest Application that performed intergration testing of the DBAccess Class with the AdventureWorks ProductPhoto table extracting the photos and writing them to a file folder. The Demo code and PowerPoint can be obained from this link.  https://skydrive.live.com/?wa=wsignin1.0&cid=29e34e9a8650bb9e#!/?cid=29e34e9a8650bb9e&sc=documents&id=29E34E9A8650BB9E%21151 Please note that I use Visual Studio 2010 Ultimate.  If you have a lesser version the Modeling projects likely will not work or have limited functionality and you should unload that project to prevent warning. Enjoy! --Ron

• Environment variable blank inside application

Am I misunderstanding about how environment variables work in Ubuntu? This is with a C++/Qt App on Ubuntu 11.10 x86.

• HTTP(S) based file server

  - by Michael

  I've got a server running Ubuntu 10.04. I've already gotten openssh for ssh and sftp on it. I've been looking for a web-based (http, or preferably https) file server, perhaps a web-front-end to an (S)FTP server, that allows access to a specific folder, and also allows uploads. It requires user authentication, preferably using PAM. This web-based solution is for users that are not allowed to use FTP software / browser extension and don't have flash / java browser plugins within their corporate environments. So far I have looked into: Webmin: Includes a file manager, however it uses Java, and I'm looking for a plugin-free implementation. Apache2: I was able to set up https and PAM authentication, but the barebone implementation doesn't include file upload (as far as I'm aware of). HFS: Haven't tried it out because it is for Windows/wine only, and I don't want to run it under wine.

• Itty bitty ITTIA DB for Java Embedded Device Development

  - by hinkmond

  Here's a nice 3rd party itty-bitty database, called ITTIA DB, for Java Embedded and Mobile development See: ITTIA DB for Java Embedded Here's a quote: Java applications on mobile devices and other embedded systems can now leverage the robust shared access and data distribution features of ITTIA DB SQL with a new JDBC (Java Database Connectivity) driver released this week. This driver provides significant value for Java developers targeting embedded platforms such as QNX and Linux. Plus, it can exchange data with an Oracle back-end database. That's good if that's what you have on the back-end. Hinkmond
