Is it a good idea to use unicode symbols as Java identifiers?
location: linuxexchange.com - date: November 1, 2014
I have a snippet of code that looks like this:
double Δt = lastPollTime - pollTime;
double α = 1 - Math.exp(-Δt / τ);
average += α * (x - average);
Just how bad an idea is it to use unicode characters in Java identifiers? Or is this perfectly acceptable?

Why is it a good idea to advise people to use sudo?
location: ubuntuforums.com - date: May 10, 2011
Okay I've been fumbling around the forums and giving some help (for better or worse).
Lots of people here advise other users to use sudo for access to superuser commands and file permissions rather than entering su directly. Personally, I hate sudo and try to avoid it as much as possible. If I have to, I use su-to-root in the DE or use a batch command to send me back to user as soon as I'm done with a set of commands.
Is there an unofficial rule here at Ubuntu Forums that all answers must be given in terms of sudo?
EDIT: Oops, I don't think this topic should go here. For future reference, which forum should I post a thread like this to?
An idea: Use an older smartphone with only USB connectivity as a password locker
location: ubuntuforums.com - date: July 17, 2014
I need a device to:
Hold passwords and other personal information that I can read and type into another device. (Yes it is slow and error-prone. But it is secure from everything except key-loggers, and can be used everywhere without dependency on net connection, third-party software, or trust of some cloud provider.)Secure this information from loss or theft should the device be lost, destroyed, or stolen.Be self contained and the information be easy to view and edit on the device.
The device I have been using for this is an old Palm m515 I carry wherever I go, but it is at the end of its working life. The modern equivalent is a smartphone. It is pocketable, has a screen, you can type into it and has a wired physical connection to back up through. It is also has a CPU powerful enough so that with the right software it could do on-the-fly encryption so the information is kept on the device in a safe manner, yet with the right credentials (master password kept between the ears) can edit
Is it good idea to have EFI partition mounted as /boot ?
location: linuxquestions.com - date: May 8, 2015
I'm going to perform fresh debian testing installation on uefi system. I want to have separate /boot, because it is probably the only way to format core filesystem with btrfs.
Some people claim it is good idea to merge /boot into efi partition.
Is it really a good idea? What are pros and cons? And what size should it have?
Is it a good idea to use HTML5 now? [closed]
location: linuxexchange.com - date: October 18, 2010
I know it will be 'finalized/made official' in 2012 (and something to do with it being given 'Recommendation status' in 2022), but I'm wondering if it's a good idea to make a site using HTML5 now.
A simple portfolio sorta site? Given that most users (most people using IE) won't have support for it, although IE9 (shock) will be shipping with support.
Old versions of linux distros is it a good idea to use them on old machines?
location: linuxquestions.com - date: February 28, 2006
Hello everyone :)
I am something of a newbie, although I'm loving the learning curve :) I've got an old laptop (Acer travelmate 507t: intel celeron 500 mhz, 64 mb ram, 2 gig hard drive, floppy, usb and cdrom) and I'm trying to install linux on it. I've had a look at several threads on here about which distro to go with, and i've had a go with DSL, which is very snazzy, but i'd like something a little more wholesome if you see what I mean. I've also had a look on linux-on-laptops and seen what other people have installed on very similar machines. People seem to be having success with SuSe and Gentoo. Slackware also seems to be fairly popular.
My question is essentially this, do older versions of linux distros run faster on older machines? For example, I think that slackware is currently up 10.2, but I can still download all the versions from 2.x onwards (i think). Would I be better off getting an older version so that it would run more smoothly, or are there more appropriate diff
Is it good idea to use google translation API for a few words?
location: linuxexchange.com - date: December 29, 2013
I'm making websites for german clients atm and I would like to make it easier for my german colleague and have all texts in my CMS translated automaticly. I would only need to ask the API for the translation once, because I'm saving the translations in database.
So I found out that google charges $20 per 1 M characters, but I would only need a few words translated now and then, something like 1000 a week max.
So I'd like to know, if there are any restrictions, that I need to use some minimum number of translations, or a minimum price for those who don't fully use the api.
64bit VirtualBox host running a single 32bit guest, good idea?
location: linuxquestions.com - date: March 19, 2010
I need to host a Windows 2003 (32-bit) guest VirtualBox image.
My machine is a top of the range Intel i7 920.
Ignoring all RAM benefits/limitations, should I install Ubuntu Server AMD64 or x86 for the host OS (along with the AMD64 or x86 versions of VirtualBox)?
Or is it bad to run 32-bit guests in 64-bit hosts?
