• lxterminal not working

  - by Dora

  My Lxterminal is not working. Here's some background: A few days ago I wanted to configure the keyboard layouts for my Lubuntu 11.10 for English and Romanian. You can find a deetailed description of what I did here: http://ubuntuforums.org/showthread.php?p=11793260 So, it worked for a few days. Today it stopped working again. So I started reading forums again. I tried to follow this forum: Switching keyboard layouts in Lubuntu 11.10 so I went up in the terminal, went into the .bashrc file and added this sudo tee -a /etc/xdg/lxsession/Lubuntu/autostart right after this: setxkbmap -layout "us,ro(winkeys)" -option "grp:ctrl_shift_toggle" Then pressed Ctrl+X and Enter. Almost at the same time I installed some system updates. A few minutes later I wanted to use the terminal again, and this is what happens: [sudo] password for dora: I type in the password but nothing happens. Also, whatever other command I try to type, it just gets returned. No errors messages, nothing. Please help. PS: Funnily, I just noticed that I am now able to type in Romanian again!

• News Applications internal working [on hold]

  - by Vijay

  How does news applications work other than RSS Feed based applications? I know some of them take the RSS content from the source site.But sometimes I see, those applications show - Title Description Date Image video etc. Even though when I see the original site's rss, image, video is not there in rss. So how does one get that to show in there applications? Some applications even shows feeds from magazine sites, newspaper sites. How do these applications work? I am creating an application which will link to different news sites feeds categorized (like top news, technology, games, articles etc.) On the front page it will show the website names, then on selection of any news site it will get the feed from that website and show it to user. So I would like to know All the fetching of data from should be done on user selection or data should be prefetched? Detailed information I want to fetch from the original like provided in the rss data. How should I go about it?

• Would this data requirement suit a Document -Oriented database?

  - by codecowboy

  I have a requirement to allow users to fill in journal/diary entries per day. I want to provide a handful of known journal templates with x columns to fill in. An example might be a thought diary; a user has to record a thought in one column, describe the situation, rate how they felt etc. The other requirement is that a user should be able to create their own diary templates. They might have a need for a 10 column diary entry per day and might need to rate some aspect out of 50 instead of 10. In an RDBMS, I can see this getting quite complicated. I could have individual tables for my known templates as the fields will be fixed. But for custom diary templates I imagine I would would need a table storing custom_field_types (the diary columns), a table storing entries referencing their field types (custom_entries) and then a third custom_diary table which would store rows matching custom_entries to diaries. Leaving performance / scaling aside, would it be any simpler or make more sense to use a document oriented database like MongoDB to store this data? This is for a web application which might later need an API for mobile devices.

• How to correctly write an installation or setup document

  - by UmNyobe

  I just joined a small start-up as a software engineer after graduation. The start-up is 4 year old, and I am working with the CEO and the COO, even if there are some people abroad. Basically they both used to do almost everything. I am currently on some kind of training phase. I have at my disposition architecture, setup and installation internal documentation. Architecture documentation is like a bible and should contain complete information. The rest are used to give directions in different processes. The issue is that these documents are more or less dated, as they just didn't have the time to change them. I will be in charge of training the next hires, and updating these documents is part of my training. In some there is a lot of hard-coded information like: Install this_module_which_still_exists cd this_dir_name_changed cp this_file_name_changed other_dir_name_changed ./config_script.sh ./execute_script.sh The issues i have faced : Either the module installation is completely different (for instance now there is an rpm, or a different OS) Either names changed, and i need to switch old names by new names Description of the purpose of the current step missing. Information about a whole topic is missing Fortunately these guys are around and I get all the information I want and all the explanations I need. I want to bring a design to the next documents so in the future people don't feel like they are completely rewriting a document each time they are updating it. Do you have suggestions? If there is a lightweight design methodology available online you can point me to it's nice too. One thing I will do for sure is set up a versioning repository for the documents alone. There is already one for the source code so I don't know why internal documents deserve a different treatment.

• Garage Sale Code &ndash; Everything must go!

  - by mbcrump

  Garage Sale Code     The term “Garage Sale Code” came from a post by Scott Hanselman. He defines Garage Sale Code as: Complete – It’s a whole library or application. Concise – It does one discrete thing. Clear – It’ll work when you get it. Cheap – It’s free or < 25 cents. (Quite Possibly) Crap – As with a Garage Sale, you’ll never know until you get it home if it’s useless. With the code I’ve posted here, you’ll get all 5 of those things (with an emphasis on crap). All of the projects listed below are available on CodePlex with full source code and executables (for those that just want to run it).  I plan on keeping this page updated when I complete projects that benefit the community.  You can always find this page again by swinging by http://garagesale.michaelcrump.net or you can keep on driving and find another sale.

• How do spambots work?

  - by rlb.usa

  I have a forum that's getting hit a lot by forum spambots, and of course the best way to defeat something is to know thy enemy. I'll worry about defeating those spambots later, but right now I'd like to know more about them. Reading around, I felt surprised about the lack of thorough information on the subject (or perhaps my ineptness to input the correct search terms for better google results). I'm interested in learning all about spambots. I've asked on other forums and gotten brush-off answers like "Spambots are always users registering on your site." How do forum spambots work? How do they find the 'new user registration' page? (I'm especially surprised because some forums don't have a dedicated URL for this eg, www.forum.com/register.html , but instead use query strings or even other methods invisible to the URL bar) How do they know what to enter into each 'new user registration' field? How do they determine what's a page they can spam / enter data into and what is not? Do they even 'view' this page at all? ..If not, then I'd assume they're communicating with the server directly - how is - this possible? How do they do it? Can forum spambots break CAPTCHAs? Can they solve logic questions (how?)? Math questions? Do they reverse-engineer client-side anti-bot validation scripts? Server-side scripts? What techniques are still valid to prevent them? Where do spambots come from? Is someone sitting behind the computer snickering as they watch their bot destroy site after site? Or are they snickering as they simply 'release' it onto the internet somehow? Are spambots 'run' by an infected computer somewhere? Do they replicate themselves? etc

• Compiz problems in Ubuntu 12.10

  - by Antonio Raffaele Iannaccone

  I have installed ubuntu 12.10 x64 on my notebook and I wanted to make a little customization in the UI, so i downloaded Compiz Settings Manager and opened it up. Once I opened it up, I found out that in the compiz are not all those settings and animations (that I could apply like on the photos, videos etc.) so I reinstalled it few times. Once I get bored with the reinstalling I checked one field in there and Ubuntu (OS) started to get "lagged" (Dash get hid, OS started to do not respond very well). So please, can anyone help me? How can I customize my ubuntu without get lagged and with all the animations that have to be available in the compiz? Thanks to all! thank you! It seems that it helped to fix the Dash-hide problem, but I still do not have all the animations and features that have to be in the Compiz (program). Can you help me with this too please? Thanks a lot!

• Internationalization messages based in views or in model entities

  - by SJuan76

  I have a small webapp in java and I am adding the internationalization support, replacing texts with labels that are defined in dictionary files. While some texts are obviously unique to each view (v.g. the html title), other refer to concepts from the model (v.g. a ticket, the location or status of such ticket, etc.) As usual, some terms will appear many times in different locations (vg, in both the edition page and in the search page and in the listings I have a "ticketLocation" label). My question is: can I organize the labels around the model concepts (so I have a ticket.location label and I use it everywhere such field is labeled) or should I make a different label for each (so form.ticketLocation and filter.ticketLocation and list.ticketLocation). I would go for the first option; I have searched for tips and the only thing that I see that could hinder me is due to the length of the string disrupting the design, and even for that I would prefer having to add a ticket.locationShort for places where there is not much space. What is your opinion/tips/experience?

• Is the capability to overwrite functions in JavaScript strength or weakness?

  - by S.N

  I recently came across the following code (from liferay.js) when I was working with Liferay: .... if (!Liferay._ajaxOld) { Liferay._ajaxOld = jQuery.ajax; } if (Liferay._ajaxOld) { jQuery.ajax = function(options) { if (Liferay.Util) { options.url = Liferay.Util.getURLWithSessionId(options.url); } return Liferay._ajaxOld(options); }; } .... As you can see, the code above overwrites the function "jQuery.ajax" to modify "options.url". One may say this is a strength of the language since we can easily overwrite and customize existing functions. However, I would imagine this capability can easily lead to a problem. For instance, my code can overwrite the same function "jQuery.ajax" to modify "options.url" differently from the code above. As a result, any code that expect the behavior defined by "liferay.js" may no longer function as expected. I see this as a weakness of the language as it does not provide proper encapsulation. What are the consensus about this feature/capability of the language in the field?

• Problem in domain name of site in google search [on hold]

  - by Jayadratha Mondal

  My domain provider dont supports advanced DNS at this moment. So I have used iframe to forward to my webserver. Suppose my domain abc.com have a simple html which is opening xyz.com via Iframe. Google was showing abc.com on the search. But from last two days it is showing xyz.com, other things like description, name of the site are ok only the domain changed to xyz.com, but I want to show abc.com. When I'm typing the full domain then google showing the domain as I want. But If I type a part or any keyword then it showing that xyz.com. Anyone have any idea how to show abc.com again? EDIT: I dont know the domain name provider because its not mine. When I'm trying to set new A record its showing that "you need advanced dns to do this currently you are using simple DNS". I'm doing this from cpanel. Normally as per I know there are 3 sections. 1 domain name 2 A record 3Cname. But I dont have any domain name section.

• There's Not an App for That (Yet)

  - by Mark Hesse

  With an earlier-than-normal departure this morning to avoid the stalemate known as traffic congestion, I suddenly realized what I had failed to grab on my way out the door...  my company ID badge.  Unfortunately, at the time of my epiphany, I was far enough into commuter no-man's land where turning back would completely negate my early departure and increase my overall drive time exponentially.  Not being one to retrace my steps, I decided to press on. Upon arrival at the office and with an hour to go before a security guard would be on duty, I started thinking about the number of times I had forgotten my ID vs. the number of times I had forgotten my phone.  While rare on both accounts, my ID was most likely the missing artifact. I then wondered why there isn't an app for my smartphone that allows me to verify my credentials with my employer and then, provided with a secure token for the day, have the ability to access my building's card entry system.  On many levels, this seems much more secure than an ID card which can be lost, stolen or even forged and then used simply by tailgating into and around buildings at facilities where card scanning can generally be avoided.   As it turns out, another building on the campus has 24 x 7 guard coverage, so I was able to gain access in a relatively short time and secure a temporary ID badge.  Once inside and online, a quick internet search on the subject of smartphone badge access shows that efforts are underway to do exactly what I was thinking needed to be done. Having not spent any time studying about the technology, I discovered that it relies on Near Field Communications (NFC) enabled smartphones (of which, mine does not provide).  The only other option would require modifications to the security infrastructure to support alternative authentication technologies, such as barcode readers, which would be extremely costly to implement. For now, my best option is to put my corporate ID under my car keys...

• NetworkManager detects no networks with a RTL8188CE

  - by Cormac O'Brien

  I'm on a 2011 Lenovo Thinkpad T420i with a Realtek RTL8188CE WiFi adapter. Here's the scenario: I pop in the Ubuntu LiveCD to install. Laptop detects all networks in range, I connect to my home network, internet working great. Once Ubuntu finishes installing, the home network I am connected to is the only one which appears in the applet list. Upon restarting or waking from suspend, NetworkManager does not detect any networks – it simply displays "Disconnected" under the Wireless Network section of the menu. I am able to connect to my home network by using the "Connect to Hidden Wireless Network" option and it works immediately. I have yet to test if this works with other SSIDs. I have tried reinstalling the entire OS as well as NetworkManager and my wireless drivers. For hardware info, I ran: cormac@cormac-T420:~$ sudo lshw -c network Here is the output for my wireless card: *-network description: Wireless interface product: RTL8188CE 802.11b/g/n WiFi Adapter vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:03:00.0 logical name: wlan0 version: 01 serial: d0:df:9a:08:73:50 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=rtl8192ce driverversion=3.2.0-26-generic firmware=N/A ip=192.168.1.138 latency=0 link=yes multicast=yes wireless=IEEE 802.11bgn resources: irq:17 ioport:5000(size=256) memory:f2500000-f2503fff I can provide more information if required. This was not a problem in Natty or Oneiric. I hope this can be fixed, I don't want to have to ask for an SSID wherever I need to connect.

• How Does Domain Know Where Your Web Host Is Located [closed]

  - by icu222much

  Possible Duplicate: How Does Domain Know Where Your Web Host Is Located? I just purchased a domain name from RapidNames, and a hosting plan at JustHost. I was told to enter JustHost's name server (ns1.justhost.com) in my domain name's name server field and wait for 24 hours for the process to be complete. I do not understand how RapidNames can find my account on JustHost's server as I am sure I am not JustHost's only customer. I have read the article How DNS Works that John Conde has posted, but I still do not understand the issue. After reading several other articles, I am beginning to understand how it works, but I would still like someone to confirm if I am correct or not. From my understanding, linking your domain name to your web host is a two step process. First, you need to tell your domain name who your web host is. This is done by providing the two DNS server addresses. Secondly, you need to tell your web host which domain names you own by entering your domain names into the domain name manager. As a result, when someone queries your domain name, they will be forwarded to your web host. The web host will look in their database to match the domain name the account's owner, and then serve the appropriate website. I want to confirm if my understanding of how a domain knows where your web host is located is accurate?

• How to build a "traffic AI"?

  - by Lunikon

  A project I am working on right now features a lot of "traffic" in the sense of cars moving along roads, aircraft moving aroun an apron etc. As of now the available paths are precalculated, so nodes are generated automatically for crossings which themselves are interconnected by edges. When a character/agent spawns into the world it starts at some node and finds a path to a target node by means of a simply A* algorithm. The agent follows the path and ultimately reaches its destination. No problem so far. Now I need to enable the agents to avoid collisions and to handle complex traffic situations. Since I'm new to the field of AI I looked up several papers/articles on steering behavior but found them to be too low-level. My problem consists less of the actual collision avoidance (which is rather simple in this case because the agents follow strictly defined paths) but of situations like one agent leaving a dead-end while another one wants to enter exactly the same one. Or two agents meeting at a bottleneck which only allows one agent to pass at a time but both need to pass it (according to the optimal route found before) and they need to find a way to let the other one pass first. So basically the main aspect of the problem would be predicting traffic movement to avoid dead-locks. Difficult to describe, but I guess you get what I mean. Do you have any recommendations for me on where to start looking? Any papers, sample projects or similar things that could get me started? I appreciate your help!

• Can't install GTX 680 drivers on 12.04

  - by user68945

  I recently installed Ubuntu 12.04 on my desktop. I have three monitors, and after installing, ubuntu only detected one at 1080p. I downloaded the driver from the nvidia website, but when I stop lightdm and try to run the driver, it gives me an error message: ERROR: Unable to find the kernel source tree for the currently running kernel. Please make sure you have installed the kernel source files for your kernel and that they are properly configured; on Red Hat Linux systems, for example, be sure you have the 'kernel-source' or 'kernel-devel' RPM installed. If you know the correct kernel source files are installed, you may specify the kernel source path with the '--kernel-source-path' command line option. I tried instead to install the driver via the terminal, with the X ppa. The installation seemed to work, but when I rebooted, my display was at 640x480 resolution, with no other options for resolution. The NVIDIA X Server settings program is there now, but when I run it, it simply tells me that I don't seem to be using their driver, and that I should run nvidia-xconfig as root. Doing so doesn't help, I simply get the same issue again. I checked the file at /etc/X11/xorg.conf, and it's an NVIDIA file (has nvidia in the header). Does anyone know something else I can try? EDIT: Forgot to mention, I tried installing drivers via the "Additional Drivers" GUI utility, there were two options, one of them marked "(post-release updates)". I tried both of them, in both cases it tried to download and install for a while, then said that there was an error, and that a description could be found at /var/log/jockey.log. Both logs were over 700 lines

• Discrete Math and Computing Course

  - by ShrimpCrackers

  I was recently admitted into a Computing and Software Systems program (basically software engineering) and one of the first courses I'll be taking is called Mathematical Principles of Computing. The course description: "Integrating mathematical principles with detailed instruction in computer programming. Explores mathematical reasoning and discrete structures through object-oriented programming. Includes algorithm analysis, basic abstract data types, and data structures." I'm not a fan of math, but I've been doing well in all my math classes mostly A's and B's ever since I started two years ago, and I've been doing math every quarter - never took a quarter without math - so I've been doing it all in sequence without gaps. However, I'm worried about this class. I've read briefly on what discrete math is and from what my advisor told me, its connection with computer science is that it has alot to do with proving algorithms. One thing that my instructors briefly touched on and never went into detail was proving algorithms, and when I tried, I just wasn't very good at mathematical induction. It's one of the things that I ignored every time it showed up in a homework problem (usually in Calculus III which I'm finishing up right now). Questions: 1. What can I expect from this class? 2. How can I prepare myself for this class? 3. Other tips? Thank you.

• Can I share data between two users in an ASP.NET Application?

  - by Dave

  I have an issue with Roles.IsUserInRole function. It take hell amount of time to just check if the logged-in user is in particular role(typ 3-9 sec). I searched to find a solution and arrived on this but I am not sure If I have fully grasped it. What I got from the above, A new derived class is created. Inside that class, there is a list which retrieves all user at once. The next time you check IsUserInRole, you do not use the actual IsUserInRole method but rather use the one you overrode in your class. Is this the correct description? Am I on track? My question is, can data be share between two different users in ASP.NET application? If yes, will the shared data exist only if there is at least one user logged in. If all users logs out, that shared data is destroyed? My point is this data will be created only one time whenever a user logs in. For all subsequent users they can use this data and check their roles against the list? I need a detailed answer. My application has users and different roles. We are using ASP.NET roles.

• Black Screen after installing recommended Nvidia drivers. What to do?

  - by former_Windows_user

  New to Ubuntu. Problem description: Until recently I had Windows on my computer. My hard disk is divided into two partitions. On the first one (app. 10 GB) I had my Windows XP On the second one (app. 30 GB) I have some data I tried to install Ubuntu 12.04 on the first partition (the smaller one). Since I wanted to keep the data on my second partition, I chose the third install option. During the installation process I deleted the data on partition one, created a new partition with the same size, formatted it as ext4 and mounted / on it. The installation continued fine and at the end I restarted and took the CD out when it ejected automatically (it could have been also before the restart). Ubuntu started but I noticed that my computer was slow. Then a prompt appeared telling me that I did not have the optimal NVidia drivers and recommended to install a specific one. I clicked on the recommended driver, installation went apparently just fine and at the end I had to restart the system again. I did it, Ubuntu started, asked for my password, I typed it, pressed Enter, the screen turned black and remained like that (only the cursor was there and I could move it). I restarted and the same thing happened again. Has anyone had such a problem before and was able to solve it? With Windows I always installed drivers from CDs after installing Windows. Are the same CDs going to work for Ubuntu too or I should find special drivers? P.S. During the installation I was connected to the internet and I agreed on installing updates and the third party software. In the time before I installed that problematic but recommended NVidia driver I checked that there was between 6 and 7 GB free space on the first partition where I installed Ubuntu.

• Scale an image with unscalable parts

  - by Uko

  Brief description of problem: imagine having some vector picture(s) and text annotations on the sides outside of the picture(s). Now the task is to scale the whole composition while preserving the aspect ratio in order to fit some view-port. The tricky part is that the text is not scalable only the picture(s). The distance between text and the image is still relative to the whole image, but the text size is always a constant. Example: let's assume that our total composition is two times larger than a view-port. Then we can just scale it by 1/2. But because the text parts are a fixed font size, they will become larger than we expect and won't fit in the view-port. One option I can think of is an iterative process where we repeatedly scale our composition until the delta between it and the view-port satisfies some precision. But this algorithm is quite costly as it involves working with the graphics and the image may be composed of a lot of components which will lead to a lot of matrix computations. What's more, this solution seems to be hard to debug, extend, etc. Are there any other approaches to solving this scaling problem?

• Distribution upgrade (12.04 -> 14.04 LTS) halted while unpacking/installing packages

  - by Bob Sully

  As the title states...it just stopped unpacking/installing. "Preparing to unpack .../lirc_0.9.0-0ubuntu5_amd64.deb ..." then stopped in its tracks. Everything else is still running. The update manager process is still alive; if I hit ctrl-c, it gives me the warning message about leaving the system in a broken state. Also, if I run top, there is a process called "trusty" which is still running. I have NOT killed either process. lsb_release -a gives: LSB Version: core-2.0-amd64:core-2.0-noarch:core-3.0-amd64:core-3.0-noarch:core-3.1-amd64:core-3.1-noarch:core-3.2-amd64:core-3.2-noarch:core-4.0-amd64:core-4.0-noarch Distributor ID: Ubuntu Description: Ubuntu 14.04.1 LTS Release: 14.04 Codename: trusty I assume that if I try to restart update-manager, I won't be offered the option to upgrade again.

• Overlapping text on top menu in Unity 12.04

  - by mercury

  So I'm new to Linux but am basically blown away by Ubuntu 12.04 and could definitely see this becoming my main desktop over time One small annoyance for me is a tendency for the global menu on the top bar to partially over-write the text description of the active window in the top panel. e.g. I focus on the "Ubuntu Software Centre" window which writes out that label in the leftmost corner of the top menu bar. If I then move the cursor up to the top menu bar to access the "file menu", this will partially overwrite the window name leaving just "Ubuntu" visible. This is a little slice of ugliness I don't want to see every day! Much easier on the eye for me would be to display the active window name at the centre of the top panel, using some of that free space and then have the global menu stay where it is, just to the right of the app launcher. I've found a solution to disable the global menu but I would prefer to keep it and instead move (or disable) the active window name in the top panel. Any way to do this?

• Lubuntu 13.04, kernel still 3.8.0-32-generic

  - by Blue Ice

  My question is very similar to Ubuntu 13.10, kernel still 3.8.0-31-generic. Recently was updating to Saucy and the ethernet cable got unplugged. So I decided to run Software Update again, to reinstall files. It returned that "everything is up to date". But according to these command-line searches, that is incorrect. How can I install Saucy now safely from the command line? sudo apt-get install lubuntu-desktop Reading package lists... Done Building dependency tree Reading state information... Done lubuntu-desktop is already the newest version. The following package was automatically installed and is no longer required: linux-image-extra-3.8.0-19-generic Use 'apt-get autoremove' to remove it. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. sudo apt-get dist-upgrade Reading package lists...

• how to deal with controller mutations

  - by Milovan Zogovic

  During development process, things are constantly changing (especially in early phases). Requirements change, UI changes, everything changes. Pages that clearly belonged to specific controller, mutated to something completely different in the future. For example. Lets say that we have website for managing Projects. One page of the website was dedicated to managing existing, and inviting new members of specific project. Naturally, I created members controller nested under projects which had proper responsibility. Later in the development, it turned out that it was the only page that was "configuring the project" in some way, so additional functionalities were added to it: editing project description setting project as a default ... In other words, this page changed its primary responsibility from managing project members to managing project itself. Ideally, this page should be moved to "edit" action of "projects" controller. That would mean that all request and controller specs need to refactored too. Is it worth the effort? Should it be done? Personally, I am really starting to dislike the 1-1 relationship between views and controllers. Its common situation that we have 1 page (view) that handles 2 or more different resources. I think we should have views completely decoupled from controllers, but rails is giving us hard time to achieve this. I know that AJAX can be used to solve this issue, but I consider it an improvisation. Is there some other kind of architecture (other than MVC) that decouples views from controllers?
