• Making backup of the System Restore Partition with netbooks

  - by devoured elysium

  I have a netbook that has two partitions. A first one where I have all my programs and stuff and a second one that came with the netbook and has the data so I can restore my computer if I need to. Now, as I had problems in the past with other computers that had a similar restore scheme, I know I must in some way do a backup of this partition, so if there is any problem I can put everything working again. How should I proceed? As this is a netbook, it doesn't have a CD reader. Maybe doing a backup of this partition to a 12GB(it seems this partition occupies this much!) usb? How could I do it? Thanks

• Connect server to router with workstation in between?

  - by letseatfood

  I have a server (9 yr old Dell with Ubuntu 10.04 Server Edition) and a workstation (Laptop with Vista) which are both connected to a router. The workstation is able to access the server via web browser for testing my web development projects. Since the server is old and does not have a wireless card, I am wondering if it is possible to connect the server directly to the workstation while maintaining the ability to connect to the server from the workstation. The reason is that the computers are in a separate room from the router and I am trying to limit the amount of wires on the floor, along with trying to avoid buying more hardware (like a wireless card). Thanks and I will be more than happy to clarify!

• Use wired LAN adapter by default

  - by Frantumn

  I am trying to find out if there's a way to set up network adapters so that if 2 are connected with network and internet access it will choose one over the other. Scenario: I have seen several computers running Windows 7 or Windows 8 where you are connected to a wireless network, working perfectly. Then when you plug in an Ethernet cable, it still shows the network icon in the taskbar as wireless. I would like to have my computer set up so that if there's an Ethernet cable plugged in, it uses that, and not the wireless adapter. 1) Is this possible / How? 2) Why does it stay on wireless over wired when given the option for both?

• Choice of programming language for learning data structures and algorithms

  - by bguiz

  Which programming language would you recommend to learn about data structures and algorithms in? Considering the follwing: Personal experience Language features (pointers, OO, etc) Suitability for learning DS & A concepts I ask because there are some books out there that are programming language-agnostic (written from a Mathematical perspective, and use pseudocode). If I learn from one of these I would like to work out the algorithms in a chosen language. Then, there are other books which introduce DS & A concepts with examples in a particular programming laguage - and I would follow these examples as well. Either way, I have to choose a language, and I would like to stick to one throughout. Which one best fits the bill.

• Can't play stream from TorrentFlux server

  - by thegreyspot

  I am trying to stream a video from my TorrentFlux-b4rt server. I tried multiple media players, none work. Only VLC was able to produce an error message: input can't be opened: VLC is unable to open the MRL 'mms://..*.*:8080/'. Check the log for details. I have tried multiple computers on different networks and all have the same issue. I am using Windows 7 to play the videos, and the server is Torrentflux-b4rt 1.0-beta2 with ubuntu 9.10.

• Laptop stopped recognizing USB hard drive

  - by vahokif

  Hi, My Packard Bell EasyNote TX86 laptop stopped recognizing my 1 TB Toshiba Store Art hard drive. It worked fine until now, and it still works on other computers. Other USB devices (including storage) work, and I've tried plugging it in every port, to no avail. When I plug it in it spins up, but Windows doesn't react at all (it's not in disk management), Linux doesn't write anything in dmesg and I can't see it in BIOS setup. I didn't use it at all today, apart from plugging it into a freshly-installed Windows 7 machine once (where it worked). What can I do? Which device is to blame here? EDIT: One more thing. I unplugged the drive while the laptop was hibernated. Google says this might be the problem and it might have something to do with resetting the USB Host Controller.

• How can I download information from bank accounts?

  - by Eric Anastas

  There are a number of free finance tracking sites out there like mint.com, wesabe.com etc.. . I've tried all of them and all seem to miss the mark in one way or another. I'm interested in creating my own website, or possibly just a stand alone windows program for tracking my finances in ASP.NET or C#.NET. I'm assuming the answer is no, but is there any way that a personal developer can download transactions from financial websites like these? I know once you login to most financial sites you can download a CSV or Quicken file. Yet I really like how I can log-in to my Mint.com account and update all my accounts with one click.

• Create, Delete and Use e-mail accounts within a website! Is it possible?

  - by BitDrink

  Hello! I'm developing an administration panel (in php), for a website (in a shared host), to let the administrator to manage the personal infos of the employees! With this panel should be possible to create or delete an e-mail account for an employee and if the employee logs in the admin panel, he/she should be able to access to his/her e-mail account! I had thought to install Horde WebMail on the website to let the employees use their e-mail accounts ... but how can I pass the login credentials to Horde? And what you suggest to create and delete the e-mails account that can be read by Horde? Any other suggestion is greatly appreciated! Thanks in advance!!! EDIT: Or are there better alternatives to Horde to accomplish, at least, the e-mail account access from within the web site?

• unusual webpage access problem

  - by user28163

  This is one of the weirdest problems I've ever seen and I'm out of ideas. I cannot access a couple of websites from my home pc (for 3-4 days now), or at least they go really really slow ~700b/s I can access these same websites fine from my laptop from same IP address. - The websites originate from different countries and are huge popular sites. - I have tried both my PC's network cards. - I have reformatted my PC. - I have reset my router to factory settings. - I have created virtual computers on my PC, and from inside those I cannot access the webpages. - I have flushed my dns. - I tried specifying my dns server addresses to 8.8.8.8 and 8.8.4.4. I can only access the webpages using my PC, if I first connect to an outside VPN. Again, these sites work fine on the 2 other pcs in this house (same ISP and internet connection). help plz :)

• How to copy files between windows 7 professional and enterprise machines?

  - by WilliamKF

  I've got a desktop system running Windows 7 Professional and a laptop running windows 7 Enterprise in a domain-joined computer and I need to copy around 50 GB of files from the Enterprise machine to the professional one. I'd rather not burn a bunch of DVDs or use my tiny flash drive of 1 GB to do the transfer. How can I mount a drive from one of the computers to the other so that I can just drag and drop? I tried using a homegroup, but the windows 7 Enterprise laptop does not see it from the professional desktop and the laptop cannot make its own homegroup since it belongs to a domain.

• My windows xp wireless hotspot wifi isn't working

  - by Dominic Grenier

  I add the hotspot the regular way. Yet it doesn't show up as available when I try to connect to it using my other Ubuntu laptop. And nothing can connect to it. Yesterday, I successfully made it work for 5 minutes and then it stopped without me changing any configuration. I've already tryed resetting the DNS. Edit: I've updated my Broadcom 802.11b/g driver to a generic but more recent version. I've also repaired the WMI, now the advanced tab of my primary connection is available and the hand meaning the connection is shared appeared. But the computers still connect the wrong way around. (Windows to ubuntu instead of ubuntu to windows) Reinstalled SP3...

• Implementing OFX specification with javascript

  - by John Langston

  Hey all, I am working on a personal project and need to retrieve financial data. After looking around how this is normally done it seems you can pay lots of money and license a service like Yodlee to get this data for you or you can implement a OFX client like wesabe has to communicate with financial institutions. Seeing as I don't have lots of money and wouldn't mind the challenge I decided to try to implement the ofx spec (unless one of you can suggest a cheap/free alternative!). I looked around for some ofx libraries other people have already written for use but didn't find anything that looked too great. I was wondering if anyone knew if it would be a bad idea to attempt this in Javascript (using XMLSocket from actionscript to handle the actual socket communication). If there is some really bad reason why I shouldn't do this please bring it up. If there is I'll just do it in Java but I think it would be neat to have it completely in javascript so it runs client-side. Anyways I was hoping for some helpful input, thanks.

• As a student looking for hands-on experience, how should I configure my test lab to accurately reflect a business setting?

  - by Moe

  I'm one class away from my BA IT, I took several classes in general IT. Out of all the books I found just two to be really beneficial, so I'm trying to get the hands on experience. I want to build a small test network that has both wireless and also wired clients, a printer, a laptop, a desktop, and server (I have 2x 1TB drives of data that I want to be available to all computers). What should I do to configure these in a way that will reflect how a small business might be set up, so that I can work towards some meaningful experience.

• Pros and Cons on where to place business logic: app level or DB

  - by Juri

  Hi, I always again encounter discussions about where to place the business logic: inside a business layer in the application code or down in the DB in terms of stored procedures. Personally I'd tend to the 1st approach, but I'd like to hear some opinions from your part first, without influencing you with my personal views. I know there doesn't exist a one-size-fits-all solution and it often depends on many factors, but we can discuss about that. Btw, we are in the context of web applications and our current approach is to have UI layer which accepts UI input and does a first, client-side validation Business layer with a number of service-classes which contains the business logic including validation for user input (server-side) Data Access Layer which calls stored procedures from the DB for doing persistency/read operations Many people however tend to move the business layer stuff (especially regarding the validation) down to the DB in terms of stored procedures. What do you think about it? I'd like to discuss.

• Prevent registry changes by users

  - by graf_ignotiev

  Background: I run a small computer lab of 10 computers using Windows 7 x64 Enterprise. Our users are set up as limited users. For additional restrictions, I set up local group policy for non-administrators using the microsoft management console. Problem: Recently, I found out that some of these restrictions had been removed. Reviewing the settings MMC and in ntuser.pol showed that the settings should still be in place. However, the related registry settings were missing in ntuser.dat. I already have registry editing disabled in the GPO (though not in silent mode). Question: What is the best way to deal with this situation? Should I look into preventing registry setting changes? Should I set up registry auditing to found out how these keys are getting changed in the first place? Or should I give up the ghost and write some kind of logon script that enforces registry values if they've been change? Any other ideas?

• Thunderbird: Synchronize tags

  - by fuenfundachtzig

  When I check my mail (via IMAP) on my laptop I'd like to see the same tags that I set when I checked my mail on my office computer. So the question is: Is it possible to synchronize user-specified mail tags between Thunderbird running on different computers? I've read that tags could be stored via IMAP on the server, so maybe it's just that the server of my mail provider does not support this IMAP feature? (Whichever it is...) Has anybody any experience with this? Related, but not my primary concern: Will there ever be a more flexible tagging system in Thunderbird which allows for an easier definition of new tags? (I.e. that a don't have to define new tags in the preferences menu, but can just type them in when reading a mail?)

• Jquery load() help

  - by mtwallet

  Hi. I am creating a portfolio page for m personal site. I have a slider with approx 20 anchors that link to projects I have worked on, each one contains a client logo that when clicked should load some html content then fade that content into a container div on the same page. I have been advised to use the JQuery method load() which seems straight forward. The question I have is do I have to repeat the following code for each of the 20 anchors as the url is different for each one or is there a more efficient way? $('a#project1').click(function() { $('#work').load('ajax/project1.html'); } Also would I have to use the unload() method first to ensure the div I am loading into is empty? Many thanks in advance.

• Listing the routing table takes long time to complete

  - by Rafal Rawicki

  When I print routes defined on my computer using route, it takes about 5 to 20 seconds to complete. Why does it take so much time? With VPN enabled: $ time sudo route Kernel IP routing table (...) real 0m21.423s user 0m0.000s sys 0m0.012s With no VPN, this is about 5 seconds - still, computer can do a lot in this time. I've repeated my measurements few times, getting very similar results each try. My machine is Ubuntu with 3.0.0 kernel, but as far as I know, route on the other computers works the same way.

• How to crop black bars or zoom on Youtube and other Video websites?

  - by cloneman

  Many desktop software (VLC, MPC) and have an option to 'zoom in' , 'crop black bars', or crop to a specific aspect ratio. How can we do this in Fullscreen on Youtube or other flash Video sites? I am the viewer, NOT the video's creator/publisher. iOS Can do this (double tap to zoom, which removes black bars, zoom depth not configurable). afaik, Desktop computers (and android devices), cannot do this on the fly. The only 'workaround' I've found is F11 and zooming of the entire web page - basically a fake full screen and zooming the web page beyond the screen size. Use Case: watching 4:3 flash videos from the web on a widescreen monitor. Looking for all creative solutions, including any software that accesses YouTube without using a web browser.

• Ways for managing the installation and configuration of various software applications and settings i

  - by EmpireJones

  What are some ways for managing the installation and configuration of various software applications and settings in group of linux development and server computers? Is a set of basic scripts a good means of attack? I was thinking about just having a ton of scripts, such as: setup_dev_env [install|uninstall|reinstall] setup_nfs [...] setup_nfs_share [...] setup_http [...] setup_memcache_node [...] Is there any better method? It would be nice to be able to "upgrade" an installation script too, for example, to change common development settings.

• How can I build a Truth Table Generator?

  - by KingNestor

  I'm looking to write a Truth Table Generator as a personal project. There are several web-based online ones here and here. (Example screenshot of an existing Truth Table Generator) I have the following questions: How should I go about parsing expressions like: ((P = Q) & (Q = R)) = (P = R) Should I use a parser generator like ANTLr or YACC, or use straight regular expressions? Once I have the expression parsed, how should I go about generating the truth table? Each section of the expression needs to be divided up into its smallest components and re-built from the left side of the table to the right. How would I evaluate something like that? Can anyone provide me with tips concerning the parsing of these arbitrary expressions and eventually evaluating the parsed expression?

• Fastest Java web templating language

  - by CaptainAwesomePants

  I'm about to start in on a new Spring MVC project, and I'm examining the various options for the view. I've never been a fan of JSP, and I've run into JSP-related performance problems in the past, so I was looking through the other options. I'm hoping that somewhere somebody's taken a census of the various options (maybe it'll have to be me) and pronounced which ones are quick, or at least which options there are. Here are the choices I've thought of, ordered from obvious to bizarre: JSP, JSTL Velocity FreeMarker GSP (Groovy JSP) ERB powered by IronRuby or some such craziness Tea Any suggestions, personal preferences, or other good options for the list?
