• downgrading a ubuntu 10.04 LTS virtual server

  - by castigli

  I am downgrading an existing ubuntu 10.04 LTS Virtual Server to one with less memory and a smaller drive ( from 80GB to 40GB ). My hoster ( hetzner.de ) does not give me the possibility of doing an inplace downgrade, so I have to create a new server. What is the best way to make an image of the first system and "apply it" to the new one ? I know there other answer but in my situation I am not sure I would be able to use Clonezilla or other GUI tools, because the installation is minimal with no GUI. Thanks in advance Michele

• How can you procedurally place objects in a non-gridded game?

  - by nickbadal

  This is a follow-up question to this question. I mistakenly worded the question, but got a good answer before I could correct myself, so I didn't want to delete it. Sorry! Now that I know that it is possible, I'd like to implement procedural world generation, but I don't want it to look gridded or blocky, where everything is obviously placed on an integer grid. I know that you can do this in gridded worlds by inputting a square's x and y into a noise function, or similar, but how can I generate a more natural looking object placement using procedural methods? This is in the context of an adventure game, if it matters.

• What are the best tools to help work with large ant files.

  - by klfox

  I just started working at a company that has a very large ant build file that imports lots of other large/small ant files. Needless to say it's giving me a headache trying to figure out what is going on. What are the best tools out there for: Getting some kind of concise answer on what is happening Visualizing the various targets Seeing performance on tasks Can be multiple tools. Any other tips/suggestions? I tagged this as java since I don't have the reputation to create an ant tag.

My questions: What is required to be on the list of contents required for general public to see? What are the most important aspects in point of web content required for users to see?

• Any idea of what to do with an old PC?

  - by phineas

  I got an old PC for free, similar to that one. Additionlly, I'm a hobbyist programmer who does mainly python and java under a linux (mostly ubuntu) development environment. And now I wonder what I could do with such a piece of crappy hardware and would be pleased to get a good answer. It's one thing if you code your app that could run on almost any pc (or webbrowser) but another if you got an own hardware platform which you could extend or more generally customize the way you like. What I would like to hear from you: Are you in a similar situation? Have you already done a project like that? What would be your ideas?

• SSL on multiple directories

  - by Shredder

  I have a website that is http, but has a port set up for https for a specific directory that is for the shopping cart. Now I'd like to use our SSL on a different directory in the same site as well. How can I go about configuring that? I have tried looking into all of the config files as well as the docs and cannot figure it out. I tried setting this in httpd.config as well <VirtualHost 127.0.0.1:[ssl port]> #also tried *:[ssl port] and [actual IP]:[ssl port] ServerAdmin [email protected] DocumentRoot "C:/path/sslNeededDir" ServerName www.example.com </VirtualHost> hoping that it would cause pages in this directory to use ssl port and become https, but that didn't do anything. Any help is greatly appreciated. Update: This finally got migrated over. I'm still looking for a solid answer on this. If anyone could help me, it would be greatly appreciated.

• Syncing between computers / batch download

  - by Eric

  I have synced files from two different devices. Now I want to copy to contents of the synced files to the other device. Using the web interface, it seems only possible to download one file at a time. Is there a way to setup automatic sync or to download all the files in a folder with one step? Thanks in advance for your time. I was using the web interface to ubuntu, but an answer for Ubuntu One would also be ok.

• Can a high FPS negatively affect how a program runs?

  - by rphello101

  Yeah I know this is a broad question and will get down rated, I'm just hoping for some answer before it gets closed. Anyway, I'm using Slick 2D/Java to play around with graphics. I'm having some trouble with trying to move an image. The weird thing is, the code works just fine on my laptop, but the image sporadically moves to (0,0) and stops on my desktop. The only difference between the two is that it says the FPS is about 500 on my laptop and 6600 on my desktop. Can that affect it or does someone have any ideas for what to check on?

• Where would a senior PHP developer locate the method getActiveEntries()?

  - by darga33

  I have a class named GuestbookEntry that maps to the properties that are in the database table named "guestbook". Very simple! Originally, I had a static method named getActiveEntries() that retrieved an array of all GuestbookEntry objects. Each row in the guestbook table was an object that was added to that array. Then while learning how to properly design PHP classes, I learned some things: Static methods are not desirable. Separation of Concerns Single Responsibility Principle If the GuestbookEntry class should only be responsible for managing single guestbook entries then where should this getActiveEntries() method most properly go? Update: I am looking for an answer that complies with the SOLID acronym principles and allows for test-ability. That's why I want to stay away from static calls/standard functions. DAO, repository, ...? Please explain as though your explanation will be part of "Where to Locate FOR DUMMIES"... :-)

• How can I redirect the contents of a file to the pastebinit command? [duplicate]

  - by Tim

  This question already has an answer here: How to submit a file to paste.ubuntu.com without graphical interface? 2 answers Whenever I was to store something to show someone here, I run command-with-output | pastebinit. That returns the link to the paste online. For example: echo timtjtim | pastebinit gave me the link paste.ubuntu.com/8010000 Which I can share. How can I do this with a file - for example a log file. Surely I don't have to open - > copy all - > open paste.ubuntu.com -> paste it?

• Math behind multivariate testing for website optimization

  - by corkjack

  I am looking for theoretical resources (books, tutorials, etc.) to learn about making sound statistical inferences given (plenty of) multivariate website conversion data. I'm after the math involved, and cannot find any good non-marketing stuff on the web. The sort of questions I want to answer: how much impact does a single variable (e.g. color of text) have? what is the correlation between variables? what type of distribution is used for modelling (Gaussian, Binomial, etc.)? When using statistics to analyze results - what should be considered as a random variable - the web-page element that gets different variations or the binary conversion-or-no-conversion outcome of an impression? There's plenty of information about different website optimization testing methods and their benefits\pitfalls, plenty of information about multivariate statistics in general, do you guys know of resources that discuss statistics in this specific context of website optimization ? Thanks for any info!

• How to create a map-like (clouds) texture [duplicate]

  - by user16547

  This question already has an answer here: How do you generate tileable Perlin noise? 9 answers If you place a map of the world on a sphere, it will look like the image is continuous. Basically the left end of the image is sort of a continuation of the right end. You won't be able to see any cuts. I'm trying to create a clouds texture to add to my planet such that it will seem it has clouds. I managed to create the clouds in GIMP, however, I can't figure out how to make sure the left end of my image is a smooth continuation of the right end. For example if you were to map the below image to your sphere (I removed transparency to make it clearer), there would be a very obvious transition from the right end of the image back to the left end on your sphere. How would I create a texture such that I get rid of that? Sorry for my lack of terminology.

• Do teams get more productive by adding more developers? [duplicate]

  - by jgauffin

  This question already has an answer here: Why does adding more resource to a late project make it later? 12 answers Suppose you've got a project that is running late. Is there any proof or argument that teams become much more productive by adding more people? I am looking for answers that can be supported by facts and references if possible. What I'm thinking about is that existing devs have to teach the new ones (thus losing overall development time), and then the new developers have to study the code (and tasks) before they can become fully productive.

• Demographics and Interests reports

  - by Dyf

  I have an issue with Google Analytics, can't seem to find a guide how to activate Demographics and Interests reports. I am using the new version of analytics (Universal Analytics) and the script code looks something like this: (function (i, s, o, g, r, a, m) { i['GoogleAnalyticsObject'] = r; i[r] = i[r] || function () { (i[r].q = i[r].q || []).push(arguments) }, i[r].l = 1 * new Date(); a = s.createElement(o), m = s.getElementsByTagName(o)[0]; a.async = 1; a.src = g; m.parentNode.insertBefore(a, m) })(window, document, 'script', '//www.google-analytics.com/analytics.js', 'ga'); But the guide i found on googles page (https://support.google.com/analytics/answer/2819948?hl=sv) is for the old version (Classis Analytics). Anyone know how i can activate this on Universal Analytics or is this even possible? Thanks!

• What happens if we serialize and deserialize two objects which references to each other?

  - by Seregwethrin

  To make it more clear, this is a quick example: class A implements Serializable { public B b; } class B implements Serializable { public A a; } A a = new A(); B b = new B(); a.b = b; b.a = a; So what happens if we serialize a and b objects into a file and deserialize from that file? I thought we get 4 objects, 2 of each. Identical objects but different instances. But I'm not sure if there's anything else or is it right or wrong. If any technology needed to answer, please think based on Java. Thank you.

• Is it possible to run two VPN clients at the same time?

  - by Manuel Selva

  I would like to run two VPN clients at the same time: one Cisco client and one VPNC client. For now I have my VPNC client configured to route only some known IPs to the VNC interface and would like to add the same thing for the Cisco client at the same time. Is it possible ? Do I need a Cisco client to connect to a Cisco server or can I use an other client such as VPNc ? I installed the cisco one because it was the one suggested but I am wondering if this is mandatory ? I guess the answer may be yes, and off course I am interested in "required configurations" to do that

• knetworkmanager not starting at all

  - by yoshi

  It seems that my knetworkmanager is not starting anymore. Read: In KDE4's sys tray I don't have a icon to manage my networks. Also when starting it from terminal or kick off menu literally "nothing" happens. I don't know what's wrong with it. Sadly after reading this answer on superuser.com it seems I can not connect to wifi via iwconfig 'cause my network is WPA2 encrypted. (Basically I can not set they passphrase - invalid argumenterror.) So it seems I've to get knetworkmanger running again as I also can't download other tools. I've tried stuff like sudo service network-manager restart but it didn't seem to help. I'm kinda puzzled so any help for this would be appreciated. PS: If it hasn't become clear: The whole drama of is simply I can't connect to wifi and internet :o)

• How to change color of the frame of a maximizing window

  - by SteliosSk

  Though I have read and tried some advises regarding the change of colors in a theme, I found no answer regarding my question, which is: When I drag a window to the left (or right or up) side of the screen an orange frame shows up, indicating the area that the window will occupy. This frame is in orange. Can you please inform me how can I change this color to blueish, to match my theme? At this point, I would like to inform you that Zorin OS has this blueish frame instead of orange, but I do not know where this color comes from.

• If you need more than 3 levels of indentation, you're screwed?

  - by jokoon

  Per the Linux kernel coding style document: The answer to that is that if you need more than 3 levels of indentation, you're screwed anyway, and should fix your program. What can I deduce from this quote? On top of the fact that too long methods are hard to maintain, are they hard or impossible to optimize for the compiler? I don't really understand if this quote encourages better coding practice or is really a mathematical / algorithmic sort of truth. I also read in some C++ optimizing guide that "dividing up a program into more functions improves its design" is frequently taught in CS courses, but it should be not done too much, since it can turn into a lot of JMP calls (even if the compiler can inline some methods by itself).

• Domain resolution - local first then external

  - by stefgosselin

  I would like to know how I can configure my dns settings so that domain is resolved locally first, then if not resolved it goes to external DNS. I had this working before, I am using Ubuntu through a VM and need the local domain to resolve first but since I have upgraded I had to reconfigure network and now it works only external, local host file does not seem to even be used. Is there an easy way to check this out? I did slap it up in google but no specific answer seemed to match my case and I too tight on delivery deadline to test-and-try different approaches. You guys rock, thanks.
