Subversion

Subversion 1.5 後終於有存 merge history,不再需要自己計算 merge 的部份。不過目前的版本問題還是不少 (目前是 1.5.1),使得使用起來還是綁手綁腳的。

一個常見的情況是錯誤的 commit:有些 developer 會把非 branch only 的修改直接 commit 到 branch 裡 (就別問為什麼會這樣了),這時候一個簡單的作法是把這個 commit merge 回 trunk。但這樣會造成 Subversion 之後要再從 trunk merge 到 branch 時混亂。目前的解法是在 trunk 再 commit 一次,然後故意 merge trunk to branch 造成 conflict,然後把他解掉。

不過這陣子開始在研究 Mercurial 了,因為 Mercurial 也有 centerialized pattern 可以中央集中管理,目前已經測的差不多,只要把 Subversion 的 post-commit 都移植過去就可以了。

Advanced printers are also utilizing resin machines that create amazingly detailed prints. So why don’t we recommend it as a top choose maybe a} finances pick? In our experience, we’ve discovered that the Ender-3 line requires extra setup and extra maintenance, and as compared with our picks it poses a much more|a way more} difficult learning curve these who|for many who|for individuals who} are just getting into 3D printing. This manual work provides many minutes of pre-print setup for a 3D-printing newcomer versus seconds for our top picks, and in flip it results in a higher Socket Organizer probability of the machine sitting in the nook gathering dust. These processes become rote after time and are made simpler by elective upgrades, however initially they require some dedication to learn. In our exams, the preliminary calibration was a slightly extra manual process than for our different picks, as the Sidewinder X2 has a Level menu that moves the extruder to preloaded points around the print mattress.
