• Suggestions on Calculating Advertising Rates [closed]

  - by Jonathan Wood

  Possible Duplicate: How do I set a price for advertising on my website? I recently launched a new developer website, Black Belt Coder. The site is only seeing about 150 visitors per day but, given that it's only been live two months, I feel I'm off to a good start. I'd like to start monetizing the site as soon as possible but consider AdSense and other programs largely a waste of time. I'd like to deal directly with the advertisers but have no idea what to charge. Are there any guidelines for determining advertising rates based on visitors or page views? I don't expect to do PPC. I want to charge a the time period for banner ads, knowing that advertisers will be keeping an eye on the number of clicks.

• Running a startup program in terminal as sudo

  - by Brandon

  I need to run a python script in a terminal, myscript.py at startup (on Lubunt). This script requires root. I've setup a .desktop file that runs the following command: lxterminal --command="python /home/d/Jarvis/alarm.py && /bin/bash" The terminal window opens at startup and runs the script, but then closes when the Python script returns an error (because it's not being run as root). When I change the Exec= to this... lxterminal --command="sudo python /home/d/Jarvis/alarm.py && /bin/bash" ... (prefixing command with 'sudo') which works. However, the terminal opens on startup and displays the [sudo] password for d: \ prompt, requiring me to input my password. I would like the execution of the python script at startup to be completely automatic with no user interaction. How can I accomplish this?

• fdisk shows overlapping partitions

  - by Campa

  At every boot to start Ubuntu, a partition gets re-mounted more than 1 times, sometimes causing very long boots. Example below: > dmesg ... [ 21.472020] EXT4-fs (sda5): re-mounted. Opts: errors=remount-ro ... [ 42.021537] EXT4-fs (sda5): re-mounted. Opts: errors=remount-ro,commit=0 ...

• How to change Port 27000 from filtered to open status

  - by Nadarajah Ranjan

  In my ubuntu box I am running flexlm licensing software on port 27000 and I am able to pull the license from the this port to run the simulation software locally. I am also trying to run the same software in another Linux machine (opensuse) by using the flexlm license from the Ubuntu box. However, my opensuse box is unable to communicate with port 27000 in my Ubuntu box. I have turned off the firewall on the Ubuntu box, played around with iptables and when I do a nmap from my opensuse box to Ubuntu box the message I get is that port 27000 is on filtered status. My understanding is that filtered status does not allow the opensuse box to communicate with Ubuntu. My question is how to change port 27000 from filtered status to open status? Hope someone can help me out. Thank you.

• Problems about responsiveness and keyboard/mousepad not working

  - by ChrisTheNoob

  So I installed Ubuntu 12.04, I'm very new at this and want to get into the world of Linux but have run into nothing but problems. I have an Acer Aspire 5553g. First off, my keyboard won't work. Second, my computer has more than enough of everything to run Ubuntu smoothly, but everything runs extremely slow. (You move the mouse and it gets there a few seconds later) It's to the point where I can't even use it and I really want to. I'm tired of Microsoft stuff and I've been looking at learning how to use Linux based operating systems for a while. Please send me some help to fix these issues and maybe some tips to help get me started. Thanks in advance chris

• How to make/use launcher?

  - by prosseek

  In ubuntu, I can run firefox with the command firefox in Terminal, or click the button in dock or panel. How does this possible with ubuntu? I googled to find the name launcher, but I don't know exactly how does it work. Q1 : How to make launcher? If I make a GUI program, does that mean that I need to create launcher to start by clicking it? Q2 : Can I make a launcher for whatever program, even if it's not a GUI program? Q3 : How to link a launcher? How can make a link to a launcher in a Desktop to start a program? Q4 : The idea of launcher is unique to ubuntu? Or if I have one launcher, can I use it for other distributions? Q5 : Why some of the program pops up its icon in Docky (firefox for example), but some of the program doesn't (p4v for example) ?

• Garbled display after Ubuntu upgrade to 2.6.32-2* kernel

  - by Matthias

  I was running Ubuntu 9 (Karmic Koala) with no problems. I recently upgraded to Ubuntu 10 (Lucid Lynx) and cannot use it normally. After I log in, the screen scrambles (a purple/green mess)--impossible to see anything, although I can get out by marking the spot on the screen to click for a restart, so Linux is working behind the scenes. If I start in recovery mode with basic graphics, I have no problems at all (other than limited functionality). If I start the old 2.6.31-22 kernel, I see a bunch of "unmountable" errors in the startup script, but I can use Linux normally with no apparent problems. I'm running an IBM ThinkPad A30 with ATI Mobility graphics. Just to reiterate, the screen looks normal until I log in, at which point it goes bonkers. What do I need to change in order to fix this?

• First time user here

  - by Brian

  Never used Linux before but I decided I want to start somewhere and Ubuntu seemed like the right place to start. I burned the 64bit version iso onto a CD and installed it onto a fresh new hard drive I got and it installed nicely or so I thought. First major problem was the fact that the screen slip oddly, second when I tried to log in everything just kind of froze, I could still move the cursor but thats it. I'm not too tech savy but I can follow instructions and any help given would be greatly appreciated. I am considering dual booting it with my other hard drive that has windows 7 on it but I'm afraid I might mess that up, plus if I do it that way I wouldn't know how to get rid of Ubuntu if I decide its not for me.

• external USB HD doesn't show up on 'sudo fdisk -l' on one Ubuntu, shows up on another (both 'precise')

  - by Menelaos

  I have a 1.5TB WD external USB HDD and two Ubuntu systems, both 'precise'. When I plug the disk on system A it doesn't show up on the output of sudo fdisk -l nor is it automatically mounted (note that that wasn't always the case - it used to appear in the past). When I plug it on system B (again Ubuntu precise) it shows up when I do a sudo fdisk -l (output appended at the end) and mounts automatically just fine. What does this discrepancy point to and what kind of diagnostics should I run / tools I should use to troubleshoot the problem? I followed the suggestion I received to do a sudo tail -f /var/log/syslog and the output is the following when I plug, unplug and replug the USB cable on System A: Sep 14 23:27:09 thorin mtp-probe: checking bus 2, device 3: "/sys/devices/pci0000:00/0000:00:13.2/usb2/2-2" Sep 14 23:27:09 thorin mtp-probe: bus: 2, device: 3 was not an MTP device Sep 14 23:28:01 thorin kernel: [ 338.994295] usb 2-2: USB disconnect, device number 3 Sep 14 23:28:04 thorin kernel: [ 341.808139] usb 2-2: new high-speed USB device number 4 using ehci_hcd Sep 14 23:28:04 thorin mtp-probe: checking bus 2, device 4: "/sys/devices/pci0000:00/0000:00:13.2/usb2/2-2" Sep 14 23:28:04 thorin mtp-probe: bus: 2, device: 4 was not an MTP device Sep 14 23:29:54 thorin AptDaemon: INFO: Quitting due to inactivity Sep 14 23:29:54 thorin AptDaemon: INFO: Quitting was requested (I guess the last two message are irrelevant).

• What is Happening vs. What is Interesting

  - by Geertjan

  Devoxx 2011 was yet another confirmation that all development everywhere is either on the web or on mobile phones. Whether you looked at the conference schedule or attended sessions or talked to speakers at any point at all, it was very clear that no development whatsoever is done anymore on the desktop. In fact, that's something Tim Bray himself told me to my face at the speakers dinner. No new developments of any kind are happening on the desktop. Everyone who is currently on the desktop is working overtime to move all of their applications to the web. They're probably also creating a small subset of their application on an Android tablet, with an even smaller subset on their Android phone. Then you scratch that monolithic surface and find some interesting results. Without naming any names, I asked one of these prominent "ah, forget about the desktop" people at the Devoxx speakers dinner (and I have a witness): "Yes, the desktop is dead, but what about air traffic control, stock trading, oil analysis, risk management applications? In fact, what about any back office application that needs to be usable across all operating systems? Here there is no concern whatsoever with 100% accessibility which is, after all, the only thing that the web has over the desktop, (except when there's a network failure, of course, or when you find yourself in the 3/4 of the world where there's bandwidth problems)? There are 1000's of hidden applications out there that have processing requirements, security requirements, and the requirement that they'll be available even when the network is down or even completely unavailable. Isn't that a valid use case and aren't there 1000's of applications that fall into this so-called niche category? Are you not, in fact, confusing consumer applications, which are increasingly web-based and mobile-based, with high-end corporate applications, which typically need to do massive processing, of one kind or another, for which the web and mobile worlds are completely unsuited?" And you will not believe what the reply to the above question was. (Again, I have a witness to this discussion.) But here it is: "Yes. But those applications are not interesting. I do not want to spend any of my time or work in any way on those applications. They are boring." I'm sad to say that the leaders of the software development community, including those in the Java world, either share the above opinion or are led by it. Because they find something that is not new to be boring, they move on to what is interesting and start talking like the supposedly-boring developments don't even exist. (Kind of like a rapper pretending classical music doesn't exist.) Time and time again I find myself giving Java desktop development courses (at companies, i.e., not hobbyists, or students, but companies, i.e., the places where dollars are earned), where developers say to me: "The course you're giving about creating cross-platform, loosely coupled, and highly cohesive applications is really useful to us. Why do we never find information about this topic at conferences? Why can we never attend a session at a conference where the story about pluggable cross-platform Java is told? Why do we get the impression that we are uncool because we're not on the web and because we're not on a mobile phone, while the reason for that is because we're creating $1000,000 simulation software which has nothing to gain from being on the web or on the mobile phone?" And then I say: "Because nobody knows you exist. Because you're not submitting abstracts to conferences about your very interesting use cases. And because conferences tend to focus on what is new, which tends to be web related (especially HTML 5) or mobile related (especially Android). Because you're not taking the responsibility on yourself to tell the real stories about the real applications being developed all the time and every day. Because you yourself think your work is boring, while in fact it is fascinating. Because desktop developers are working from 9 to 5 on the desktop, in secure environments, such as banks and defense, where you can't spend time, nor have the interest in, blogging your latest tip or trick, as opposed to web developers, who tend to spend a lot of time on the web anyway and are therefore much more inclined to create buzz about the kind of work they're doing." So, next time you look at a conference program and wonder why there's no stories about large desktop development projects in the program, here's the short answer: "No one is going to put those items on the program until you start submitting those kinds of sessions. And until you start blogging. Until you start creating the buzz that the web developers have been creating around their work for the past 10 years or so. And, yes, indeed, programmers get the conference they deserve." And what about Tim Bray? Ask yourself, as Google's lead web technology evangelist, how many desktop developers do you think he talks to and, more generally, what his frame of reference is and what, clearly, he considers to be most interesting.

• BIDS Helper 1.6 Beta Release (now with SQL 2012 support!)

  - by Darren Gosbell

  The beta for BIDS Helper 1.6 was just released. We have not updated the version notification just yet as we would like to get some feedback on people's experiences with the SQL 2012 version. So if you are using SQL 2012, go grab it and let us know how you go (you can post a comment on this blog post or on the BIDS Helper site itself). This is the first release that supports SQL 2012 and consequently also the first release that runs in Visual Studio 2010. A big thanks to Greg Galloway for doing the bulk of the work on this release. Please note that if you are doing an xcopy deploy that you will need to unblock the files you download or you will get a cryptic error message. This appears to be caused by a security update to either Visual Studio or the .Net framework – the xcopy deploy instructions have been updated to show you how to do this. Below are the notes from the release page. ====== This beta release is the first to support SQL Server 2012 (in addition to SQL Server 2005, 2008, and 2008 R2). Since it is marked as a beta release, we are looking for bug reports in the next few months as you use BIDS Helper on real projects. In addition to getting all existing BIDS Helper functionality working appropriately in SQL Server 2012 (SSDT), the following features are new... Analysis Services Tabular Smart Diff Tabular Actions Editor Tabular HideMemberIf Tabular Pre-Build Fixes and Updates The Unused Datasets feature for Reporting Services now accounts for new features in Reporting Services 2008 R2 like Lookups and new features in Reporting Services 2012. SSIS: emit an informational message when a variable has an expression defined and EvaluateAsExpression = False SSAS: roles reports points to wrong server SSIS - Variable Copy / Move broken in v1.5 "Unused DataSets Report" not showing up in Context menu on VS2005 if Solution Folders used SSAS Tabular: Create a UI for managing actions SSAS Tabular: Smart Diff improvements for new schema and Tabular models SSIS: Copy/Move Variable Erroring due to custom Control Flow item Icon SSIS Performance Visualization Index out of range fixing bugs in AggManager when aggregation design IDs don't match names The exe downloads are a self extracting installer, the zip downloads allow for an xcopy deploy. Make sure to note the updated xcopy deploy instructions for SQL Server 2012.

• Checking if %Y exists in current file in VimScript [closed]

  Like the title says. I would love to know how, with VimScript, I can do an if statement, that checks if %Y (for statusline) exists in the current file. This is what I have so far: if expand('%:Y') != "" let filetype=extend('%:Y') let filetype+= ",\ " else let filetype="" endif This is, of course, for my statusline, for which I don't want to show the filetype comma and space if the filetype doesn't exist.

• Booting 11.10 from USB stick on MacBook Pro 5,1 fails

  - by Helge Stenström

  I've created a bootable memory stick on a Windows computer, and tested it on an HP PC. It's made from a 64-bit image of Ubuntu 11.10, downloaded from http://www.ubuntu.com/download/ubuntu/download. When I boot from this memory stick, there is some kind of boot menu, where I can choose to run Ubuntu from the memory stick, or install. I select Run from memory stick. (the words may be wrong here, I'm taking it from memory.) From this point, the screen is black (but backlighted), and I can't do anything but turn off the computer. It gets hot, too. Has anyone been more successful than me? Are there known issues? The computer is a 15 inch MacBook Pro 5,1 (unibody, late 2008), 4 GB memory.

• Trying to update Asus BIOS: FreeDOS crashes

  - by ZekeDroid

  My UX31 zenbook is experiencing some weird shutdown behavior when the battery drops below 50% and the internet seems to agree that updating the BIOS is a good step forward since there were issue with the kernel before. I downloaded both the correct BIOS file and the windows 7 utility tool and now need to boot FreeDOS to run, however, I've tried every method out there and they all fail (or so I think): Using unetbootin's FreeDOS 1.0 image I get to an error saying it couldn't run drivers then I get to a command line on disk A:. I assumed a dead end. Using unetbootin but with the FreeDOS 1.1 version image downloaded directly: get an error of "bad or missing command interpreter". I looked online and the solutions didn't work either. So, is there an alternative to FreeDOS or to installing a BIOS that I could use?

• Assessing Relative Maintainability

  - by João Bragança

  We (a contractor, actually) are implementing an off the shelf system to replace a legacy homegrown system for the core domain of the company (designing widgets). Unfortunately both systems will have to run concurrently for some time, as the product just isn't ready yet. Also, the decision was made to only migrate some of the widgets from the legacy system, based on date of last sale activity. Later on a new requirement came down: certain people in the company, most of them outside of the widget development context, want to search all widgets. The search results screen has 3 pieces of data: a GUID, a human readable id that is searchable, and a brief description (may need to be searchable in the future). In the widget details, there will be multiple screens. These screens align very well along SOA / bounded context lines - a screen for marketing data, a screen for sales history, etc. UML ahead! I am probably using the wrong kind of arrows here so please forgive me. The current solution - which is not in production yet - is something like the following: Both systems will be queried and the controller will merge the results. The new system has its own proprietary query language (we've alleviated this a bit with a LINQ provider). It also puts a lot of data on the wire. 15 search results typically run about 60k of unintelligible SOAP-wrapped xml. So I would prefer to avoid querying this system directly. These two systems publish events to help us integrate with other systems, mainly an ERP system. One of these events contains all the data necessary for the search screen. I proposed the following alternative: However I am being told that 'adding another database' will create more maintenance down the road. However, I believe this to be false, as I had to add a relatively simple feature that took several hours longer than anticipated because of this merging code. I want to get a feel for which system is more maintainable in the long run. I personally have not had the burden of maintaining any large system. I want something more than my gut. Specifically I'd like to know if having more, specialized physical databases is more or less maintainable than having less larger physical databases.

• What to do with my "unmounted drive"?

  - by Taylor Guistwite

  I just recently followed the tutorials on http://www.ubuntu.com/download/ubuntu/download for installing the ubuntu server onto my 1TB Seagate External. I was planning on using this to install it on my macbook and in these instructions it states to preform this line of code Run diskutil unmountDisk /dev/diskN (replace N with the disk number from the last command; in the previous example, N would be 2) Now my HD prompts "The disk you inserted was not readable by this computer". Would I just run diskutil mountDisk /dev/diskN in order to be able to access all my files again? here is a screenshot to the instructions i followed http://i17.photobucket.com/albums/b97/hello_screamo/Screenshot2011-11-11at113914AM.png
