• Low "time on site" and high bounce-rate in Japan

  - by Noam

  I'm seeing a substantially low "time on site" and high bounce rate from visitors coming from Japan. Comparing to other states, even in languages I don't speak, the stats are still dramatically worse. So I assume there's something specific to that nation, that I should understand in order to make their experience better. The content they are seeing is in Japanese, and I've also translated the head-lines, which to my surprise didn't make stats look better. The site doesn't have a mobile version, so I assume that might be part of the problem. Wanted to hear from your experience what other reasons might there be that are specific for Japan. UPDATE: The content itself was in Japanese all the time, that's the reason it attracts users from Japan. The head-lines were in English, so I only changed them.

• How do I manually install the package selections presented in tasksel?

  - by joe

  If you forgot to select some software at the "Software Selection" screen on a fresh install, what are the commands to install them after the fact. I know you can install them manually at anytime after everything is said and done, but what are the commands to install just as if you [*]starred them on that screen. For instance: sudo apt-get install lamp-server^ will install the LAMP Server. What are the commands for the DNS Server, Mail Server and Tomcat Java server?

• Can I use Ubuntu Server to replace our Windows environment?

  - by Aaron English

  I have recently been put in charge of a network overhaul for our company. I have done plenty with Ubuntu in school but it has been a few years. I would like to replace our current servers with Ubuntu, although I am unaware if it will work. Our current environment runs a Domain, Exchange, and VPN. I know there are solutions capable for this. I guess my man worry is will windows 7 and windows XP be able to use Ubuntu as a Domain Controller? If anyone has had success with this I would love some input. I have a meeting in a couple months that I am suppose to explain our plan. Thank you.

• Login speed varies over time

  - by Brock Dute

  I have a weird problem with my Ubuntu right now. My login speed is never consistent for months, sometimes it changes within weeks. What I mean is, for example, within 2 weeks, boot time is really fast and speedy but then say after that, boot time becomes noticeably slower. Usually, right after the ubuntu login sound plays, my desktop would've finished loading already but sometimes, the ubuntu login sound is already done playing and I'm still in this stage of the login -- image, exactly like that. Any reasons for this? Sometimes it slows down after updates (which I think is kind of normal?) After a few reboots, it becomes fast then randomly it becomes slow again.

• Analog and digital audio output at the same time

  - by wim

  My speakers use a digital input, but my headphones use an analog input. I have them both plugged in, and when I want to use the headphones I just turn off the speakers and switch on the headphones. I know that simultaneous output on digital and analog is supported by the hardware, because it worked fine in Windows XP. But on Ubuntu, I seem to only get one at a time, depending on which setting is selected in the combo box located at System -> Preferences -> Sound -> Hardware. How can I get simultaneous analog and digital output without having to switch the profile every time? I'm on Ubuntu 11.04 and it's an HDA Intel chip.

• Bouncing ball slowing down over time

  - by user46610

  I use the unreal engine 4 to bounce a ball off of walls in a 2D space, but over time the ball gets slower and slower. Movement happens in the tick function of the ball FVector location = GetActorLocation(); location.X += this->Velocity.X * DeltaSeconds; location.Y += this->Velocity.Y * DeltaSeconds; SetActorLocation(location, true); When a wall gets hit I get a Hit Event with the normal of the collision. This is how I calculate the new velocity of the ball: FVector2D V = this->Velocity; FVector2D N = FVector2D(HitNormal.X, HitNormal.Y); FVector2D newVelocity = -2 * (V.X * N.X + V.Y * N.Y) * N + V; this->Velocity = newVelocity; Over time, the more the ball bounced around, the velocity gets smaller and smaller. How do I prevent speed loss when bouncing off walls like that? It's supposed to be a perfect bounce without friction or anything.

• How to set Qwt path to the run-time linker in Xubuntu

  - by Rahul

  I've successfully installed Qwt in Xubuntu 12.04(qmake - make - make install). But now I need to set the Qwt path to run time linker of Xubuntu. In manual it's given like - If you have installed a shared library it's path has to be known to the run-time linker of your operating system. On Linux systems read "man ldconfig" ( or google for it ). Another option is to use the LD_LIBRARY_PATH (on some systems LIBPATH is used instead, on MacOSX it is called DYLD_LIBRARY_PATH) environment variable. But being newbie to Linux environment, I'm not able to proceed further. Please help me with this.

• Expected time for an CakePHP MVC form/controller and db make up

  - by hephestos

  I would like to know, what is an average time for building a form in MVC pattern with for example CakePHP. I build 8 functions, two of them do custom queries, return json data, split them, expand them in a model in memory and delivers to the view. Those are three queries if you consider and an array to feed view for making some combo box. Why? all these, because I have data from json and I split them in order to make row of data like a table. Like that I changed a bit the edit.ctp but not a lot. And I created a javascript outside, with three functions. One collects data the other upon a change of a combo returnes the selected values, and does also some redirection flow. All this, in average how much time should it take ?

• 12.04 - why does the network icon dissapear every time my machine is turned off

  - by Howard Walker

  After spending an hour or two working out how to find the network Icon, I find that when I reboot the machine, I have to go through the whole procedure again. 1. The network menu is not there - so first I have to find the terminal. This has no particular location that I can find but usually I have to type terminal in the dash. 2. Then I have to type nm-applet in terminal 3. The network manager icon then appears, but only works if the terminal window remains open. Shut down the terminal window and the network disappears. This is a pain - plus I have to type my password in every time, which is another waste of time, thought this has always been a problem. So can anyone tell me how to make the web automatically connect at startup without any intervention from me.

• Movie Poster Colors Over Time

  - by Jason Fitzpatrick

  This spectrograph-like image records tens of thousands of movie posters over the course of a century, showing a steady shift towards posters that emphasize black, purple, and blue color tones. It’s a neat look at how the color tastes of an entire industry shift over time. Vijay Pandurangan had a disagreement with a friend about whether or not movie posters were becoming darker/bluer over time. Rather than simply agree to disagree, he whipped up a piece of code that downloaded and analyzed thousands of movie posters proving that, in fact, there was a slow and steady shift towards darker and bluer posters. Hit up the link below to see the interactive version (and larger!) version of his infographic as well as his explanation of the process and the source code.

• Re-generating SQL Server Logins

  SQL Server stores all login information on security catalog system tables. By querying the system tables, SQL statements can be re-generated to recover logins, including password, default schema/database, server/database role assignments, and object level permissions. A comprehensive permission report can also be produced by combining information from the system metadata.

• Point-in-time restore of database backup?

  - by TiborKaraszi

  SQL Server 2005 added the STOPAT option for the RESTORE DATABASE command. This sounds great - we can stop at some point in time during the database backup process was running! Or? No, we can't. Here follows some tech stuff why not, and then what the option is really meant for: A database backup includes all used extents and also all log records that were produced while the backup process was running (possibly older as well, to handle open transactions). When you restore such a backup, SQL Server...(read more)

• What is the Big-O time complexity of this algorithm

  - by grebwerd

  I was wondering what the run time of this small program would be? #include <stdio.h> int main(int argc, char* argv[]) { int i; int j; int inputSize; int sum = 0; if(argc == 1) inputSize = 16; else inputSize = atoi(argv[i]); for(i = 1; i <= inputSize; i++){ for(j = i; j < inputSize; j *=2 ){ printf("The value of sum is %d\n",++sum); } } } n S floor(log n - log (n-i)) = ? i =1 and that each summation would be the floor value between log(n) - log(n-i). Would the run time be n log n?

• What are my choices for server side sandboxed scripting?

  - by alfa64

  I'm building a public website where users share data and scripts to run over some data. The scripts are run serverside in some sort of sandbox without other interaction this cycle: my Perl program reads from a database a User made script, adds the data to be processed into the script ( ie: a JSON document) then calls the interpreter, it returns the response( a JSON document or plain text), i save it to the database with my perl script. The script should be able to have some access to built in functions added to the scripting language by myself, but nothing more. So i've stumbled upon node.js as a javascript interpreter, and and hour or so ago with Google's V8(does v8 makes sense for this kind of thing?). CoffeeScript also came to my mind, since it looks nice and it's still Javascript. I think javascript is widespread enough and more "sandboxeable" since it doesn't have OS calls or anything remotely insecure ( i think ). by the way, i'm writing the system on Perl and Php for the front end. To improve the question: I'm choosing Javascript because i think is secure and simple enough to implement with node.js, but what other alternatives are for achieving this kind of task? Lua? Python? I just can't find information on how to run a sandboxed interpreter in a proper way.

• Real Time Monitoring System using .net [closed]

  - by sameer

  I need to develop the application which display the dashboard where data from various SQL DB is fetched from different servers and displayed. Now this need to happen real time we can have refresh time say 5 min. Here is my thought, suggest if anything is wrong. 1) To Develop the Windows Service to accumulate the data from various SQL Server Instance. 2) Then Persist those details into SQL DB from which Dashboard will displayed on the web page. 3) Fetch of data from Windows service will be trigger every x minutes. 4) SQL Server Instance details will be stored in SQL DB which Windows Service will be referring. Thus this approach make sense. Thanks..

• Recommendations for finding part-time consultancy work

  - by Mark Heath

  Although I have a full-time development job, I have occasionally done some part-time paid work in evenings / weekends for various people who have contacted me as a result of open-source projects I have worked on. It's a nice way to earn a bit of extra cash, but obviously it is not always available. My question is, what is a good way of getting your name out there to do some small projects? I have seen a few programmers-for-hire type websites, but I don't know which I can trust or whether there are too many people willing to work for very low prices. Also, being UK based, I would want something which did not assume I have a US bank account.

• Consolidating SQL Server Error Logs from Multiple Instances Using SSIS

  SQL Server hides a lot of very useful information in its error log files. Unfortunately, the process of hunting through all these logs, file-by-file, server-by-server, can cause a problem. Rodney Landrum offers a solution which will allow you to pull error log records from multiple servers into a central database, for analysis and reporting with T-SQL.
