• apt-get upgrade stuck at the same package

  - by decibyte

  Current status I've started to suspect this is not an Ubuntu issue, but related to the internet connection here at my work. Until I'm sure, Im leaving my question below: Original question I'm stuck, can't upgrade my system. Running sudo apt-get upgrade gives me the following: mmm@alalunga:~$ sudo apt-get upgrade Reading package lists... Done Building dependency tree Reading state information...

It's at its 13th download attempt at the moment of writing. The actual downloads seem to be done just fine, but whatever it does after downloading seems to be failing. I tried removing openjdk-6, but then it wanted to install openjdk-7 instead, with the same result, hanging at openjdk-7-jre-headless instead. I also tried changing servers from my local (Danish) to the main server. No luck. It's also keeping me from upgrading alle the other packages. What to do? Update After following instructions in the answer by @lpanebr, it is now stuck at the linux-firmware package. So, maybe it's a more general problem than being related to specific package(s)? Although it did download some packages without problems before getting stuck at linux-firmware.

• System Settings -> Additional Drivers is empty. How then do I install proprietary drivers?

  - by learner

  I use Ubuntu 12.04. My graphics card is Geforce GT540M. I opened Synaptic Package manager and installed the following: nvidia-common nvidia-settings-update nvidia-common nvidia-current nvidia-current-updates The following were installed before(when unity launcher looked normal): jockey-common psensor nvidia-settings jockey-gtk xserver-xorg-video-nouveau My intention was to use the right Nvidia drivers. But apparently it didn't rightly install the drivers and now I have Unity 2D running!

• Choice of Input / music / graphics libraries for an indie game - what factors should I consider?

  - by RusselMeMan

  I was wondering which tools (grapics-sound-input libraries, game engine libraries) that the following indie games used: Braid Superbrothers: S&S Super Meat Boy Limbo Fez (I know this one is XNA) Also, what is in common use in production games? My guess for game development in C++ is: -DirectX is most common for  Windows games -SDL or SDL+OpenGL is most common for  Linux games -OpenGL + Apple APIs are most common for OSX development What do most indie game projects use? If I wanted to casually build my own game for fun in C++ with the idea of possibly releasing it to Steam or something someday, is there anything I should be concerned about if I make it with DirectX for music/sound/input and build my own game engine? Thanks!

• "Untrusted packages could compromise your system's security." appears while trying to install anything

  - by maria

  Hi I've freshly installed Ubuntu 10.4 on a new computer. I'm trying to install on it application I need (my old computer is broken and I have to send it to the service). I've managed to install texlive and than I can't install anything else. All software I want to have is what I have succesfuly installed on my old computer (with the same version of Ubuntu), so I don't understand, why terminal says (sorry, the terminal talks half English, half Polish, but I hope it's enough): maria@marysia-ubuntu:~$ sudo aptitude install emacs Czytanie list pakietów... Gotowe Budowanie drzewa zaleznosci Odczyt informacji o stanie... Gotowe Reading extended state information Initializing package states...

To continue, enter "Yes"; to abort, enter "No" I was trying to install other editors as well, with the same result. As I decided that I might be sure that I know the package I want to install is secure, finaly I've entered "Yes". The installation ended succesfuly, but editor don't understand any .tex file (.tex files are for sure fine): this is pdfTeX, Version 3.1415926-1.40.10 (TeX Live 2009/Debian) restricted \write18 enabled. entering extended mode (./Szarfi.tex ! Undefined control sequence. l.2 \documentclass {book} ? What's more, I've realised that in Synaptic Manager there is no package which would be marked as supported by Canonical... Any tips? Thanks in advance

• Collaborative Organizations build Organizational Culture

  “A Collaborative organization builds its culture based on the idea of the family or an athletic team.”(Hoefling, 2001) As I grew up, I participated in many different types of clubs, civic organizations, and sports teams.  Now looking back at the more successful undertakings, I can see three commonalities amongst them. They all shared a defined purpose or goal, defined functional roles, and a shared sense of responsibility to the group. Defined Purpose or Goal In order to unit people to work together, they must share a common goal or have a common purpose. An example of this would be the Lions Club International Foundation. There purpose is to help everyone to lead healthier and more productive lives, nurtures the potential of youth, promotes health, serves the elderly, empowers the disabled and helps victims of disasters. This organization holds localized meetings across the world and works in conjunction with other localized clubs within there organization along with other organizations to promote common goals. If there are no common goals for the group, then there is nothing that binds people to the group, and nothing will be done. Defined Functional Roles In order for an organization to work and function as a team, they must have defined roles and everyone must know how their roles are interdependent on each other. Lets shed light on this subject by looking at a football team’s offense.  Each player has an assigned role to play each time the ball is snapped. The offensive line blocks for the running back or quarterback, the quarterback passes the ball to the wide receiver or hands it off to the running back and the running back and wide receivers run with the ball towards the goal line. Each member of this team shares a common goal of scoring a touchdown, but if each team member does not fulfill their assigned roles the offences will collapse and the team will lose yards. This will provide a set back to the teams goal of scoring a touchdown because they potential are then farther away from the goal line.  In addition, if all the players do not know their roles and how they are part of a larger team then even larger yard losses can occur. Shared Sense of Personal Responsibility to the Group Shared responsibility comes with the shared common goals. Each person in the organization must do their part to promote the common shared goal or purpose based on their abilities. A prime example of this is a wrestling team competing in a match. Points are awarded to the team based on how many wins the team achieves in the meet and of that how many wins where won by decision or by pin. If a wrestler pins his opponent the teams will receive 2 points for the win, but if the wrestler wins by decision, then the team only gets one point for the win. So it is the responsibility of each person on the team to not get pinned if they are unable to win the match. If the team member gets pinned then the other team receives an additional point for the win. References: Hoefling, T. (2001).

• What Counts for a DBA: Skill

  - by drsql

  “Practice makes perfect:” right? Well, not exactly. The reality of it all is that this saying is an untrustworthy aphorism. I discovered this in my “younger” days when I was a passionate tennis player, practicing and playing 20+ hours a week. No matter what my passion level was, without some serious coaching (and perhaps a change in dietary habits), my skill level was never going to rise to a level where I could make any money at the sport that involved something other than selling tennis balls at a sporting goods store. My game may have improved with all that practice but I had too many bad practices to overcome. Practice by itself merely reinforces what we know and what we can figure out naturally. The truth is actually closer to the expression used by Vince Lombardi: “Perfect practice makes perfect.” So how do you get to become skilled as a DBA if practice alone isn’t sufficient? Hit the Internet and start searching for SQL training and you can find 100 different sites. There are also hundreds of blogs, magazines, books, conferences both onsite and virtual. But then how do you know who is good? Unfortunately often the worst guide can be to find out the experience level of the writer. Some of the best DBAs are frighteningly young, and some got their start back when databases were stored on stacks of paper with little holes in it. As a programmer, is it really so hard to understand normalization? Set based theory? Query optimization? Indexing and performance tuning? The biggest barrier often is previous knowledge, particularly programming skills cultivated before you get started with SQL. In the world of technology, it is pretty rare that a fresh programmer will gravitate to database programming. Database programming is very unsexy work, because without a UI all you have are a bunch of text strings that you could never impress anyone with. Newbies spend most of their time building UIs or apps with procedural code in C# or VB scoring obvious interesting wins. Making matters worse is that SQL programming requires mastery of a much different toolset than most any mainstream programming skill. Instead of controlling everything yourself, most of the really difficult work is done by the internals of the engine (written by other non-relational programmers…we just can’t get away from them.) So is there a golden road to achieving a high skill level? Sadly, with tennis, I am pretty sure I’ll never discover it. However, with programming it seems to boil down to practice in applying the appropriate techniques for whatever type of programming you are doing. Can a C# programmer build a great database? As long as they don’t treat SQL like C#, absolutely. Same goes for a DBA writing C# code. None of this stuff is rocket science, as long as you learn to understand that different types of programming require different skill sets and you as a programmer must recognize the difference between one of the procedural languages and SQL and treat them differently. Skill comes from practicing doing things the right way and making “right” a habit.

• Why do I get a 403 error when accessing my apache server?

  - by nishan

  Im running Ubuntu 12.04 LTS on a system with 2 GB RAM and a 500 GB HDD. My hard drive has 4 partitions: Partition 1 = 40 gb Windows (NTFS, lable = win32) Partition 2 = 320 gb Windows (FAT label = common) Partition 3 = 40 gb Ubuntu (EXT4) I installed apached2. Then, to change its default www directory, I ran gksu gedit /etc/apache2/sites-enabled/000-default and, in the editor, changed the location to /media/common/www. After that I ran these commands in a terminal: chmod 777 /media/common/www chmod 777 /media/common/www/*.* After that I ran: firefox 127.0.0.1/index.php It said: Forbidden You don't have permission to access / on this server.

• Is hidden content (display: none;) -indexed- by search engines? [closed]

  - by user568458

  Possible Duplicate: How bad is it to use display: none in CSS? We've established on this site before (in this question) that, since there are so many legitimate uses for hiding content with display: none; when creating interactive features, that sites aren't automatically penalised for content that is hidden this way (so long as it doesn't look algorithmically spammy). Google's Webmaster guidelines also make clear that a good practice when using content that is initially legitimately hidden for interactivity purposes is to also include the same content in a <noscript> tag, and Google recommend that if you design and code for users including users with screen readers or javascript disabled, then 9 times out of 10 good relevant search rankings will follow (though their specific advice seems more written for cases where javascript writes new content to the page). JavaScript: Place the same content from the JavaScript in a tag. If you use this method, ensure the contents are exactly the same as what’s contained in the JavaScript, and that this content is shown to visitors who do not have JavaScript enabled in their browser. So, best practice seems pretty clear. What I can't find out is, however, the simple factual matter of whether hidden content is indexed by search engines (but with potential penalties if it looks 'spammy'), or, whether it is ignored, or, whether it is indexed but with a lower weighting (like <noscript> content is, apparently). (for bonus points it would be great to know if this varies or is consistent between display: none;, visibility: hidden;, etc, but that isn't crucial). This is different to the other questions on display:none; and SEO - those are about good and bad practice and the answers are discussions of good and bad practice, I'm interested simply in the factual 'Yes or no' question of whether search engines index, or ignore, content that is in display: none; - something those other questions' answers aren't totally clear on. One other question has an answer, "Yes", supported by a link to an article that doesn't really clear things up: it establishes that search engines can spot that text is hidden, it discusses (again) whether hidden text causes sites to be marked as spam, and ultimately concludes that in mid 2011, Google's policy on hidden text was evolving, and that they hadn't at that time started automatically penalising display:none; or marking it as spam. It's clear that display: none; isn't always spam and isn't always treated as spam (many Google sites use it...): but this doesn't clear up how, or if, it is indexed. What I will do will be to follow the guidelines and make sure that all the content that is initially hidden which regular users can explore using javascript-driven interactivity is also structured in way that noscript/screenreader users can use. So I'm not interested in best practice, opinions etc because best practice seems to be really clear: accessibility best practices boosts SEO. But I'd like to know what exactly will happen: whether any display: none; content I have alongside <noscript> or otherwise accessibility-optimised content will be be ignored, or indexed again, or picked up to compare against the <noscript> content but not indexed... etc.

• Legally, can I re reuse code for different customers?

  - by canice

  The company I work for develops custom factory automation applications for multiple customers. Even though each application is custom, they contain common code which is re-used across projects. One of the customers is now looking for the source code to their application, which has caused a major storm in the company. Management have decided that we can't give them the source to the shared components as they are used by other customers. I've been asked to modify the shared components 'enough' so as they aren't common. So my questions are: 1) Legally, should there be any problem with re-using common components for different customer? 2) If I really need to modify the common components, then how much is 'enough' ? (I know this sucks, but I either do this or hand in my notice). Oh yeah, and my company has no license in place with any of these customers.

• N-Tier Architecture - Structure with multiple projects in VB.NET

  - by focus.nz

  I would like some advice on the best approach to use in the following situation... I will have a Windows Application and a Web Application (presentation layers), these will both access a common business layer. The business layer will look at a configuration file to find the name of the dll (data layer) which it will create a reference to at runtime (is this the best approach?). The reason for creating the reference at runtime to the data access layer is because the application will interface with a different 3rd party accounting system depending on what the client is using. So I would have a separate data access layer to support each accounting system. These could be separate setup projects, each client would use one or the other, they wouldn't need to switch between the two.

• Retrieving image from database using Ajax

  - by ama

  I'm trying to read image from database with Ajax, but I could not read the xmlhttp.responseText to the img src. The image is saved as binary data in database and also retrieved as binary data. I'm using Ajax in JSP, because I want to give the user the ability to upload images and I will view the last uploaded image, on mouse over action the Ajax will be activated and get the image back, the problem is in reading the img from the response. This is the Ajax function: function ajaxFunction(path) { if (xmlhttp) { var s = path; xmlhttp.open("GET", s, true); xmlhttp.onreadystatechange = handleServerResponse; xmlhttp.send(null); } } function handleServerResponse() { if (xmlhttp.readyState == 4) { var Image = document.getElementById(Image_Element_Name); document.getElementById(Image_Element_Name).src = "data:" + xmlhttp.responseText; } } I also got exception in the server: 10415315 [TP-Processor1] WARN core.MsgContext - Error sending end packet java.net.SocketException: Broken pipe at java.net.SocketOutputStream.socketWrite0(Native Method) at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:92) at java.net.SocketOutputStream.write(SocketOutputStream.java:136) at org.apache.jk.common.ChannelSocket.send(ChannelSocket.java:537) at org.apache.jk.common.JkInputStream.endMessage(JkInputStream.java:127) at org.apache.jk.core.MsgContext.action(MsgContext.java:302) at org.apache.coyote.Response.action(Response.java:183) at org.apache.coyote.Response.finish(Response.java:305) at org.apache.catalina.connector.OutputBuffer.close(OutputBuffer.java:281) at org.apache.catalina.connector.Response.finishResponse(Response.java:478) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:154) at org.apache.jk.server.JkCoyoteHandler.invoke(JkCoyoteHandler.java:200) at org.apache.jk.common.HandlerRequest.invoke(HandlerRequest.java:283) at org.apache.jk.common.ChannelSocket.invoke(ChannelSocket.java:773) at org.apache.jk.common.ChannelSocket.processConnection(ChannelSocket.java:703) at org.apache.jk.common.ChannelSocket$SocketConnection.runIt(ChannelSocket.java:895) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:685) at java.lang.Thread.run(Thread.java:619) 10415316 [TP-Processor1] WARN common.ChannelSocket - processCallbacks status 2

• Automatically add links to class source files under a specified directory of another project in Visu

  - by Binary255

  I want to share some class source files between two projects in Visual Studio 2008. I can't create a project for the common parts and reference it (see my comment if you are curious to why). I've managed to share some source files, but it could be a lot more neat. I've created a test solution called Commonality. The Solution Explorer of the Commonality solution which contains project One and Two: What I like: All class files under the Common folder of project One are automatically added to project Two by linking. It's mostly the same as if I would have chosen Add / Existing Item... : Add As Link on each new class source file. It's clear that these files have been linked in. The shortcut arrow symbol is marking each file icon. What I do not like: The file and folder tree structure under Common of project One isn't included. It's all flat. The linked source files are shown under the project root of project Two. It would look much less cluttered if they were located under Common like in project One. The file tree structure of the Commonality solution which contains project One and Two: $ tree /F /A Folder PATH listing for volume Cystem Volume serial number is 0713370 1337:F6A4 C:. | Commonality.sln | +---One | | One.cs | | One.csproj | | | +---bin | | \---Debug | | One.vshost.exe | | One.vshost.exe.manifest | | | +---Common | | | Common.cs | | | CommonTwo.cs | | | | | \---SubCommon | | CommonThree.cs | | | +---obj | | \---Debug | | +---Refactor | | \---TempPE | \---Properties | AssemblyInfo.cs | \---Two | Two.cs | Two.csproj | Two.csproj.user | Two.csproj~ | +---bin | \---Debug +---obj | \---Debug | +---Refactor | \---TempPE \---Properties AssemblyInfo.cs And the relevant part of project Two's project file Two.csproj: <ItemGroup> <Compile Include="..\One\Common\**\*.cs"> </Compile> <Compile Include="Two.cs" /> <Compile Include="Properties\AssemblyInfo.cs" /> </ItemGroup> How do I address what I do not like, while keeping what I like?

• is there a downside to putting N in front of strings in scripts? Is it considered a "best practice"?

  - by jcollum

  Let's say I have a table that has a varchar field. If I do an insert like this: INSERT MyTable SELECT N'the string goes here' Is there any fundamental difference between that and: INSERT MyTable SELECT 'the string goes here' My understanding was that you'd only have a problem if the string contained a Unicode character and the target column wasn't unicode. Other than that, SQL deals with it just fine and converts the string with the N'' into a varchar field (basically ignores the N). I was under the impression that N in front of strings was a good practice, but I'm unable to find any discussion of it that I'd consider definitive. Title may need improvement, feel free.

• Query total page count via SNMP HP Laserjet

  - by Tim

  I was asked to get hold of the total pages counts for the 100+ printers we have at work. All of them are HP Laser or Business Jets of some description and the vast majority are connected via some form of HP JetDirect network card/switch. After many hours of typing in IP addresses and copying and pasting the relevant figure in to Excel I have now been asked to do this on a weekly basis. This led me to think there must be an easier way, as an IT professional I can surely work out some time saving method to solve this issue. Suffice it to say I do not feel very professional now after a day or so of trying to make SNMP work for me! From what I understand the first thing is to enable SNMP on the printer. Done. Next I would need something to query the SNMP bit. I decided to go open source and free and someone here recommended net-snmp as a decent tool (I would like to have just added the printers as nodes in SolarWinds but we are somewhat tight on licences apparently). Next I need the name of the MIB. For this I believe the HP-LASERJET-COMMON-MIB has the correct information in it. Downloaded this and added to net-snmp. Now I need the OID which I believe after much scouring is printed-media-simplex-count (we have no duplex printers, that we are interested in at least). Running the following command yields the following demoralising output: snmpget -v 2c -c public 10.168.5.1 HP-LASERJET-COMMON-MIB:.1.3.6.1.2.1.1.16.1.1.1 (the OID was derived from running: snmptranslate -IR -On printed-media-simplex-count Unlinked OID in HP-LASERJET-COMMON-MIB: hp ::= { enterprises 11 } Undefined identifier: enterprises near line 3 of C:/usr/share/snmp/mibs/HP-LASER JET-COMMON-MIB..txt .1.3.6.1.2.1.1.16.1.1.1 ) Unlinked OID in HP-LASERJET-COMMON-MIB: hp ::= { enterprises 11 } Undefined identifier: enterprises near line 3 of C:/usr/share/snmp/mibs/HP-LASER JET-COMMON-MIB..txt HP-LASERJET-COMMON-MIB:.1.3.6.1.2.1.1.16.1.1.1: Am I barking up the wrong tree completely with this? My aim was to script it all to output to a file for all the IP addresses of the printers and then plonk that in Excel for my lords and masters to digest at their leisure. I have a feeling I am using either the wrong MIB or the wrong OID from said MIB (or both). Does anyone have any pointers on this for me? Or should I give up and go back to navigationg each printers web page individually (hoping not).

• Error: Multilib version problems found

  - by Kovács Ákos

  What causes this error? Error: Multilib version problems found. This often means that the root cause is something else and multilib version checking is just pointing out that there is a problem. Eg.: 1. You have an upgrade for glibc which is missing some dependency that another package requires. Yum is trying to solve this by installing an older version of glibc of the different architecture. If you exclude the bad architecture yum will tell you what the root cause is (which package requires what). You can try redoing the upgrade with --exclude glibc.otherarch ... this should give you an error message showing the root cause of the problem. 2. You have multiple architectures of glibc installed, but yum can only see an upgrade for one of those arcitectures. If you don't want/need both architectures anymore then you can remove the one with the missing update and everything will work. 3. You have duplicate versions of glibc installed already. You can use "yum check" to get yum show these errors. ...you can also use --setopt=protected_multilib=false to remove this checking, however this is almost never the correct thing to do as something else is very likely to go wrong (often causing much more problems).
