I have been trying to install Ubuntu 12.04 on my system since tomorrow, I know there newer versions of Ubuntu available, but still I want to install this version only.  I'm repeatedly getting the same error when I try to install Ubuntu on my system. I checked the md5 hash of the ISO file i downloaded but it is correct. I'm installing Ubuntu from my USB drive.  Please help me out, I need an OS to be installed on my PC. Because I don't have one.
I tried to use the usb-creator.exe from Ubuntu 10.10 desktop i386 ISO image and it does create an USB stick that doesn't boot. When I try to boot from it I get:     Operating System not found.   I try to do this from Windows 7 x64. I'm not looking to create a live Ubuntu media, only an installation USB disk.  I repeated the process several times and I even tried to reformat the USB drive (FAT32), no success yet.  The USB stick is a 8GB one.
Alternatives to one-way ANOVA for heteroskedastic data Why is there a controversy on whether mass increases with speed? Some people say that mass increases with speed, some people say that the mass of an object is independent of its speed.  I understand how some (though not many) things in physics are a matter of interpretation based on one's definitions. But I can't get my head around how both can be 'true' is any sense of the word.  Either mass increases or it doesn't, right?  Can't we just measure it, and find out which 'interpretation' is right? e.g.: (in some sophisticated way) heat up some particles in a box and measure their weight?  ------------------------------  UPDATE  Right, so I've got two identical containers, each with identical amounts of water, each on identical weighing scales, and each in the same g field. If one container has hotter water, will the reading on its scale be larger than the other? If the answer is yes, and g is constant, does this mean that the m in w=mg has got bigger?

How to solve configure: error: readline library not found? I have an Ubuntu 10.04 LTS server with a minimal install that I want to compile postgres on. With the minimal install the server did not have gcc so I had to do an apt-get install gcc but now I keep getting this error from the postgres ./configure.  configure: error: readline library not found   I can't seem to find the name of the package that contains the readline library. So I have two questions.   What is the name of the package that contains readline? Is there some way given the error message above for me to find the associated package from its standard name? Can we have a red/status tag for "obsolete"? Given the changes that have been rolled out on Meta for the new close hold reasons, we've lost "too localized" here on meta.  However, "too localized" has a genuine use on meta (which is part change management system) to indicate those things which are truly obsolete (as evidenced by the text of the old close reason "refers to a specific point in time").  That said, there are things that are obsolete on meta, but we have no way of indicating that other than an "off topic" closure, which really sends the wrong message.  To mitigate that, I'd like a status-obsolete tag for meta sites which meta diamonds can apply to posts that have been made obsolete by other changes that were made to the system afterward. Disabling module with config sync and removing with composer I have an issue disabling modules, I've searched but cannot find something useful:  - Developer A disable module and via composer remove it  - I pull his changes so i run composer install that remove the code, then drush cim to update configuration, but it complains that the module is missing while it's trying to delete its configurations.  What's the right way to do this? I can't import config before running composer install because along the uninstalled module there could be also new modules needed for the configuration import. According to WolframAlpha,  but I don't know how I can prove it. What is the significance of the name Bleach? The name "Bleach" seems to be having no relevance to the plot unlike most other series. Was it just chosen at Kubo-sensei's whim or does it have some significance? Maybe some cultural significance associated with shinigami, etc. that I am now aware of? Block any query in BIND How can I classify data with the nearest-neighbor algorithm using Python? Say you have a stick which breaks randomly into three pieces (we can choose the points randomly). What is the probability that the area is greater than or equal to $0.4$?   I can see it has something to do with Heron's formula but I just can't put t together. If $\lim_{x \to +\infty} f'(x) = L$, then $\lim_{x \to \infty} \frac {f(x)}{x} = L$ I'm trying to solve this question:     Let $f:[0,+\infty) \to \mathbb{R}$ be derivable and $\lim_{x \to +\infty} f'(x) = L$, then $\lim_{x\to \infty}\frac {f(x)}{x}=L$.   I'm trying to solve this question using l'Hôpital rule, but I couldn't use it, because I don't know if $\lim_{x\to +\infty} f(x)=+\infty$.  I need help.  Thanks a lot. Difference between a Structure and a Union What should I do when Ubuntu freezes? Do different "Picture styles" affect RAW output? I was  the manual of my camera (Canon 50D, but I am sure that each DSLR offer the same kind of functionality, albeit I don't know the exact names adopted) and noticed the issue of Picture styles which I had overlooked in my first reading.   In short I think that they are a collection of various calibration settings (more or less enhanced colours, things like that...). Those that are available on my camera are:   Standard Portrait Landscape Neutral Faithful  Monochrome 3 user definable modes.   These styles are so important to deserve a direct button just under the LCD screen of the camera (I guess this is useful for simplifying the use of the camera in the basic modes as opposed to manual / less automated ones).  And now for the question:   These settings obviously affect the appearance of the picture "as it comes out of the camera". But given the raw file I assume that they are all equivalent, a style is not applying a destructive transformation to the raw data, isn't it?  Shooting raw, is there a reason to favor one of these styles (Neutral?) over the other? Up to now I have been using Standard.   As a bonus (don't know if it deserves a separate question, in which case I will ask it again), what is the difference between Neutral and Faithful? When do I use the PHP constant "PHP_EOL"? When is it a good idea to use ?  I sometimes see this in code samples of PHP. Does this handle DOS/Mac/Unix endline issues?
