グランドが共通なので、6回路でなくて4回路でも良いし、きちんと浮かせるためには、グランドが筐体と絶縁されるタイプのジャックを使う方が良い。
In those days, I thought, golly, there are zillions of bug tracking packages
out there. Every programmer has written a dinky bug tracking package. Why
would anyone buy ours? I knew one thing: programmers who start businesses
often have the bad habit of thinking everybody else is a programmer just like
them and wants the same stuff as them, and so they have an unhealthy tendency
to start businesses that sell programming tools. That's why you see so many
scrawny companies hawking source-code-generating geegaws, error catching and
emailing geegaws, debugging geegaws, syntax-coloring editing tchotchkes,
ftping baubles, and, ahem, bug tracking packages. All kinds of stuff that only
a programmer could love. I had no intention of falling into that trap!
Of course, nothing ever works out exactly as planned. FogBUGZ was popular.
Really popular. It accounts for a significant chunk of Fog Creek's revenue and
sales are growing steadily. The People won't stop buying it.
