If you're often moving between different sheets in #Excel and you don't know View > New Window, you're seriously missing out. I think my #productivity in Excel has gone up 35% since I realised it!

The longer you spend on places like X, you realise that 2 perceptions exist:
* The grass is greener on the other side [mine v theirs]
* The person is meaner on the other side [us v them]

Every x'mas day, the #Ruby core team releases Ruby - and soon after, we get the RubyInstaller for #Windows and I try to update my post for installing #RubyOnWindows.

Did #Ruby on #Windows change the gem installation path? I installed Ruby as normal and was surprised it now installs gems to %HOME%.local/share/gem/ruby/4.0.0 - I'd prefer it to write to the Ruby directory so I can control disk space & move things easily :-)

Any idea why on Windows 11, the HOME variable is set as %HOMEDRIVE%%HOMEPATH% but it's *not* expanded? Both %HOMEDRIVE% and %HOMEPATH% are set correctly, i.e., to C: and \Users\Mohit but HOME is not set to C:\Users\Mohit somehow.
This is messing up a bunch of things with #Ruby for me.

"Best practice" is a misnomer and, at best, misleading.
It really is: "pretty good guidance for defaults till you've understood enough to appreciate context and nuance, and can choose and explain alternative choices"

I'm super excited to peak here for the first time and meet the local Ruby community! We will have a big new JRuby release by then with 4.0 compatibility and a bunch of optimizations.
Psst... see this gift under the Christmas tree? Let's unbox it 🎄
@headius.bsky.social joins us at #wrocloverb to show how you can level up your Ruby with JRuby - bringing true parallelism, pauseless garbage collection, and JIT optimizations to your Rails apps.
This one’s a real treat! 🎁

ActiveRecord has become practically synonymous with SQL database access in Ruby, but it's not the only way to talk to SQL stores. Today we'll explore Sequel, a wonderfully rich tool for interacting with many different SQL RDBMSes.

I finally wrote up how to change the default icon for some of the #Microsoft #Office file types since the new icons don't look so good at small sizes. I find the new ones (right) easier to identify. Maybe, it helps you?

A JRuby user upgrading an old app recently filed a bunch of bugs about poor perf versus CRuby. In almost every case, it was an optimization or logic change we never knew about, and once added JRuby is faster. If something isn't as fast in JRuby as in CRuby, it's a bug. Report it!
