  • Backup, clean install and restore

    - by Tony Martin
    Due to the route I came into Ubuntu I now have 12.10 upgraded from 12.04 on an NTFS file system. I've invested a lot of time getting everything as I want it, vis packages installed and settings, etc. I wonder if there is an easy method of: 1 Backing up the whole system so that I can; 2 Do a squeaky clean install of 12.10 on ext4 with bells and whistles then; 3 Restore my backup so that my system behaves as it did before the reinstall? Sorry if this seems terribly obvious, but I don't want to find all the problems when it's too late. TIA.

  • Learning about security and finding exploits

    - by Jayraj
    First things first: I have absolutely no interest in learning how to crack systems for personal enrichment, hurting other people or doing anything remotely malicious. I understand the basis of many exploits (XSS, SQL injection, use after free etc.), though I've never performed any myself. I even have some idea about how to guard web applications from common exploits (like the aforementioned XSS and SQL injection) Reading this question about the Internet Explorer zero-day vulnerability from the Security SE piqued my curiosity and made me wonder: how did someone even find out about this exploit? What tools did they use? How did they know what to look for? I'm wary about visiting hacker dens online for fear of getting my own system infected (the Defcon stories make me paranoid). So what's a good, safe place to start learning?

  • Web interface with FastCGI or with direct HTTP?

    - by Basile Starynkevitch
    Let's assume I want (for fun at start) to play with some new DSL (domain specific language) idea. And I really want its user[s] (probably only me at first) to interact thru a web interface. I'll probably implement it in C++ (probably using LLVM). Should I use an HTTP server library (like libonion or microhttpd) to talk directly HTTP or should I use FastCGI? In particular, I am noticing that several recent web frameworks (Opa, Ocsigen, ...) do not have any FastCGI interface but only HTTP one.... So my feeling is that FastCGI is really out of fashion.... Any opinions on that? Do you know recently started project using FastCGI ? (and what about SCGI?)

  • grub recover command line

    - by Rakesh Mohan Hallen
    Recently the service provider link suddenly broke,while I was updating. Then suddenly while I was trying to boot, i could not. The message on my screen was grub recover missing, and I had no option but the grub recover command line. I really did not know what to do. So I installed an earlier version of ubuntu 10.04. It started to boot normally. Now my system is back to 12.04 the version i was working with. How does one handle problems like this?

  • no back light on my acer aspire 5734z

    - by Dave
    I installed Ubuntu (12.04) on my acer aspire 5734z and the back light stopped working. I have tried the fix by editing the grub file posted on here a couple of days ago but that hasn't fixed it. I have also looked for hardware drivers but that didn't get me anywhere. When I hook up an external monitor it works fine but i have been unsuccessful getting the laptop display to light up. Thanks edit removed link I found a fix here " http://crunchbanglinux.org/forums/post/66562/#p66562 " if anyone has a better fix than the one in that post, let me know.

  • 2 min video about the SQL_Compare

    - by CatherineRussell
    It is nice to start blogging again! I am working on new project in a small company now. We do not have a full time database admin. I have to cover multiple roles: getting requirements, writing docs and creating diagrams, designing app, writing code, testing and DBA role. I am not a DBA. But, I have to do day to day database changes: adding new new columns and tables. Check out 2 min video about the SQL_Compare. This tool saves time by automatically comparing and synchronizing database schemas; eliminate mistakes migrating database changes from dev, to test, to production; speed up the deployment of new database schema updates; generate T-SQL scripts to update one database to match the schema of another; find and fix errors caused by differences between databases;  keeps an accurate history of all previous database records.  http://www.red-gate.com/products/SQL_Compare/index.htm

  • Moving camera, or camera with discrete "screens"?

    - by Jacob Millward
    I'm making a game with a friend, but having trouble deciding on a camera style. The basic idea for the game, is having a randomly generated 2-dimensional world, with settlements in it. These settlements would have access to different resources, and it would be the job of the player to create bridges and ladders and links between these villages so they can trade. The player would advance personally by getting better gear, fighting monsters and looking for materials in the world, in order to craft and trade them at the settlements. My friend wants to use an old-style camera, where the world is split into a discrete number of screens that the player moves between. Similar to early Zelda dungeons, or Knytt Stories. This is opposite to me, as I want a standard camera that follows the player around as I feel the split-screen style camera limits the game. Can anyone argue the case either way? We've hit a massive roadblock here and can't seem to get past it.

  • Clonezilla failing as soon as image copying begins

    - by mmr
    I have been trying unsuccessfully to create an image of an Ubuntu 10.04 laptop system. As soon as the copying itself starts, the entire system crashes to a black screen. I suspect that the problem is overheating, and that's why I put an ice pack under the machine. That seems to have helped a bit, but it's still not getting through the copying process. Is there any other possible explanation for dying to a black screen like this? I'm just not relishing the task of removing the hard drive, mounting it elsewhere, and then doing a backup that way.

  • What is the best way to bypass China firewall to allow SSH deploy@**.com

    - by Lap
    I am trying to bypass the china firewall and allow SSH deploy@**.com at the command console. This is because I need to test the games I wrote on apps.facebook.com/**. I tried VPN (both pptp and openvpn), but they aren't that great as connection speed slows down significantly. Since I am deploying the game in another site, my browser needs to download the game, which is super slow. What are ways of bypassing the firewall other than getting a VPN? I was thinking maybe have a computer outside China and using teamviewer to access...

  • Web-based CMS for mobile app

    - by JWood
    I'm just about to start developing a mobile app which needs to be fed from a CMS. I started designing the tables when I thought there must be something out there which could save me a load of time and let me concentrate on the mobile side of things. So, I'm looking for a CMS that will let me create hierarchical "pages" which will just be 4-5 database fields with a simple front-end to allow to edit and update them. I don't mind having to write some code to layout the database and forms etc, any saving on starting from scratch would be good. The only requirement is that I be able to access the data via some sort of web service, REST, JSON, XML, anything really... Can anyone suggest anything that might help? Thanks, J

  • Ubuntu boots up maintenance shell?

    - by Andrew
    Any time I try to start up my computer it goes to a screen titled GNU GRUB version 1.99-12ubuntu5 I can then choose from 5 different options. If I try to just boot Ubuntu, with Linux 3.0.0-20-generic it then goes to a screen saying: mountall: /lib/x86_64-linux-gnu/libc.so.6: version 'GLIBC_2.14' not found (required by /lib/libply.so.2) General error mounting filesystems. A maintenance shell will now be started. CONTROL-D will terminate this shell and reboot the system. root@Brown126:~# Control-D just brings me back to the first screen. And nothing works in recovery mode. How can I fix this?

  • Is it any good to use binary arithmetic in a C++ code like "C style"?

    - by user827992
    I like the fact that the C language lets you use binary arithmetic in an explicit way in your code, sometimes the use of the binary arithmetic can also give you a little edge in terms of performance; but since I started studying C++ i can't really tell how much i have seen the explicit use of something like that in a C++ code, something like a pointer to pointer structure or an instruction for jumping to a specific index value through the binary arithmetic. Is the binary arithmetic still important and relevant in the C++ world? How i can optimize my arithmetic and/or an access to a specific index? What about the C++ and the way in which the bits are arranged according to the standard? ... or i have taken a look at the wrong coding conventions ... ?

  • Putting altered social media logo icons on my website, can I get sued?

    - by Håkan Bylund
    I would say most websites with a somewhat thought-through graphical design use social media icons (i.e twitter, facebook, youtube, et.c) which are altered to fit the theme and design of the site. Now, my boss insist we only use the ones provided by say facebook or twitter themselfes (in fear of getting sued or lose credability), but sometimes it just doesnt look very good on the site. What is the common practice for these things? What do you risk by using an altered logo? What should I tell my boss? I'll provide a few examples, what'd happen if I put any of these on a site?

  • Should I add old code into my repository?

    - by Ben Brocka
    I've got an SVN repository of a PHP site and the last programmer didn't use source control properly. As a result, only code since I started working here is in the Repo. I have a bunch of old copies of the full code base saved in files as "backups" but they're not in source control. I don't know why most of the copies were saved nor do I have any reasonable way to tag them to a version number. Due to upgrades to the frameworks and database drivers involved, the old code is quite defunct; it no longer works on the current server config. However, the previous programmers had some...unique...logic, so I hate to be completely without old copies to refer to what on earth they were doing. Should I keep this stuff in version control? How? Wall off the old code in separate Tags/branches?

  • How to fix? Gnome-shell shows up and instantly stop working

    - by Dario
    I am using ubuntu 12.04, but I love gnome shell, but not the Gnome Classic which comes installed. When I reinstalled, I instantly installed Gnome-shell by terminal using Unity, it worked for a while and then I started installing some extensions. I rebooted and it just stopped working, it shows up for a second, then I can only see my desktop with icons but without panels and I can't even use the terminal (CTRL + ALT + T) since the window doesn't really select when I click it. How could I fix this? I tried reinstalling Gnome-shell and all the stuff I installed for it, but now it doesn't work even without any extension.

  • Easy way of engaging non-programmers (i.e. designers) into using version control?

    - by Kevin
    What are some key ways of getting your team involved in using version control during development, web development or otherwise? I refuse to work without it, which means anyone involved in the project must also use it. It's just good practice. GUIs like Tower have helped, but the concept of it is either met with anger ('not my job!' kinda attitude), timidness, or just straight up not using it (using FTP instead, circumventing version control for say, dev or deployment). Edit: I should have clarified a little that I don't just mean images/PSDs.

  • Poor Customer Service Example

    - by MightyZot
    Lately I have been frustrated by examples of poor customer service. At least one is worth writing about because I don’t think companies realize the effects of their service policies on loyal customers. Bad Customer Service Example #1 Recently, I received an offer in the mail from my cable company, suddenLink. The offer was for an updated TiVo for $12/mo. Normally I ignore offers like this one because I already have the service they’re offering and many times advertisers are offering alternatives to what is already an excellent product offering. I tend to exhibit a high level of loyalty to the products and brands that I use. In this case, we were looking to upgrade our TiVo and this deal is attractive for several reasons: I don’t want to pay a huge amount up-front for the device, so paying a monthly amount for the device is attractive to me. My entertainment is almost all on a single invoice. I’m no longer going to be billed by suddenLink and TiVo. TiVo is still involved, so I am still loyal to the brand I love. I have resisted moving to other DVRs and services for over a decade. I called suddenLink to order the new TiVo and was rewarded with great customer service. In fact, I can’t remember ever getting poor customer service from suddenLink. They are always there to answer my technical support questions and they are very responsive to outages. Then I called TiVo. First of all, I chose the option on the phone system to change or cancel my service, which was consequently met by an inordinate hold time. (I’m calling this time inordinate because I get through very quickly if I want to purchase something.) This is a trend that I’ve noticed with companies – if you want me to be loyal to you, it should be just as easy to cancel your service as it is to purchase it. Because, I should never be cancelling because I am unhappy. And, if you ever want my business again, or more importantly a reference, then you’d better make the exit door open just as easy as the enter door. After quite some time on hold, I talked to “Victor” who was very courteous. Victor canceled my service and then told me that I could keep my current TiVo and transfer recorded programs to it from the new TiVo.  Cool I said, but what about the cost?  He said there was no extra cost.  This was also attractive to me because I paid for my TiVo and it would be good to use it for something at least.  That was four months ago. This month I noticed that TiVo was still charging me for my original service. I was a little upset, but I decided to give them the benefit of the doubt. After all, I am a loyal TiVo customer and I have resisted moving to other solutions for over a decade. I’m sure they will do whatever it takes to keep my business, through TiVo or through suddenLink. After quite some time on hold, I was able to talk to a customer service representative, “Les”. I explained that I am a loyal TiVo customer, but I purchased this deal through my cable provider. I’m still with TiVo, I just wanted a single bill and to take advantage of the pay-over-time option. “Les” told me that he was very sorry to hear that I’m leaving TiVo, to which I responded again that I wasn’t leaving TiVo, I just want one invoice, and to take advantage of the pay-over-time. So, after explaining that I requested a termination of the non-suddenLink account (TiVo can see both of course), I was put on hold again for quite some time while my refund was “approved”.  “Les” said that he could see my cancellation request back in July. Note that it is now November, so they have billed me inappropriately four times. After quite some time, he came back on the line and told me that he was able to “get me most of my money back.” He got approval to refund 90 days. Even though I requested cancellation of one of my accounts, TiVo has that cancellation request on file and they admit overbilling me, I am going to get “most” of my money back. To top this experience off, when we were ready to hang up, “Les” told me that he was sorry to see me go and that he hoped I would come back to TiVo again. Again, I explained to “Les” that I have not left TiVo. I am just paying them through suddenLink. At that point, he went into a small dissertation about how this is a special arrangement they have with suddenLink and very few others. He made me feel like I was doing something wrong. Why should I feel that way? TiVo made the deal with suddenLink, not me, and the deal seemed like a good compromise for me to be able to get what I need. Here is what TiVo Customer Service accomplished on those two calls – I no longer feel like I need to be loyal to the TiVo brand or service. If I had been treated better on these two calls, I would still be recommending TiVo to my friends. They would still be getting revenue from a loyal customer, who paid the same rate for over a decade, and this article wouldn’t be here for you to read. Interesting… In my opinion, if you want brand loyalty, be loyal to your customers!

  • my wiki site using mediawiki - databases not found error

    - by Jayapal Chandran
    I had been using mediawiki opensource in my website to display programming articles. Today i tried to access my site but it showed database not found. Mediawiki uses many databases. When i logged in my control panel and checked i can see that most of the databases created by mediawiki is missing so is the reason i am getting this error. I have used mediawiki for two different purposes. It is like two modules. For one the databases are missing and for the other i think the data is corrupt. Do anybody know any issue with mediawiki security or would this be a problem with the webhosting cause we have faced several problems with them initially like before three years and recently the were good. Yet this happened. I have requested to hosting company to look into it and meanwhile i am expecting the help from stackexchange users. How do i check the logs for table deletion?

  • Creating Google sitemap.xml , is it okay for the images to be wrapped in url tags?

    - by AzizAG
    I'm using a tool to generate the sitemap.xml file for me, it started to crawl my website, got the pages and all images, but when exporting it, I review the xml(to make sure nothing is wrong) and I noticed that the images in my website are wrapped in url tags(I think it should be in image tags). See this: <url><loc>http://mywebsite.com/images/12.jpg</loc><lastmod>2012-05-23T13:39:02+00:00</lastmod><changefreq>weekly</changefreq><priority>0.50</priority></url> Shouldn't it be wrapped in image tag?(just like videos wrapped in video tag) Thanks.
