コードレビューを研く

Vaidehi JoshiさんのCrafting Better Code Reviews記事の翻訳です。

人間と技術の関係はいつの時代でも単純や楽には決して言えない。特に技術を作る人にくると、それが明らかになる。私自身も、職業でコードを書く人として、もっともコードレビューの際に痛感する。

開発の人は作業をアートに近い目線でみて(そういうところは美術作家などのクリエーターと同様)、自分のコードへの愛着が非常に強くなりがちだ。開発はエゴを捨てるべきと、自分のコードだけじゃなくて見る機会があるマージ待ちコードはすべてしっかり見るべきだと言われる。書いたコードをみてもらうのも、同僚のコードをみるのも、スバラシイコト™でやるべきことだって。推奨されるそんな習慣を身につけてちゃんとやっている人も少なくはない。


Ubuntu 17.04 new Terminal

I use Terminal a lot. I vaguely remember there being a time when I was frustrated about having to start it up to do stuff, but by now it’s my natural go-to for basically everything from just finding files to applying replay gain to a whole folder tree.

I also use two screens and three workspaces (one for idle browsing, one for focused work and one just for GitKraken and Clementine), so I tend to have multiple Terminal instances running in parallel. However, with the upgrade to 17.04, getting there got harder.


rm -rf

There are few things as scary as the command rm -rf. It deletes everything (it’s allowed to) without asking, recursively. Use it in the wrong place or on the wrong target and welcome to the “oh fuck” zone.

I don’t think I’ve ever had it run amok though, mostly because I don’t use the -f switch much. If something can’t be trivially deleted then it should ask me just in case. There are really damn scary stories out there about how bugs combined with rm -rf can ruin stuff.

I don’t exactly know how I ended up in the situation I did. The root of all evil was a hardlink to a directory on my server. I thought Ubuntu didn’t allow that (my server runs Ubuntu too and I just tested locally that it doesn’t let me create one), but it was still there in my www folder, pointing at the folder that contained my blog’s stuff.

Yeah, past tense.


Setting up nginx reverse proxy

I once set up nginx reverse proxy before, but I was just pasting stuff from online tutorials, not really understanding what I was doing. So when earlier today I decided I’d set up nginx to serve as a reverse proxy both for Apache and for node.js and Rails projects (soon to be) running on my server, I basically had to learn it all from scratch again.

Since everything on my server is now secured with SSL, I had to combine the methods from various sources on Git, Stack Overflow and Digital Ocean. My idea of the request flow was like this:


Ubuntu DNS errors

Basically every Ubuntu upgrade I run into this issue of my network connection dropping all the time – at least it looks that way. What temporarily solves it is clicking the “Auto Ethernet” item in the Network menu, but when it happens once every few minutes, it gets pretty frustrating. Especially since plenty of JavaScript based sites don’t handle sudden errors like that properly so I often ended up clicking on the retweet button a bunch of times before I realized something was wrong and confirmed it was my connection (again) in the browser’s console.

It kept throwing errors like DNS_PROBE_FINISHED_BAD_CONFIG and various other DNS related errors (NXDOMAIN, NO_INTERNET). Searching the net gives plenty of options for possible points of failure, and fixing the NetworkManager.conf (that was overwritten during the upgrade) helped me before.


My new job

For two months now, I’ve been working as a Ruby on Rails developer in downtown Tokyo. It’s a whole different world compared to working in anime. Instead of working from 1pm to midnight (though in bicycle distance from home), I now work regular hours 10am-7pm (though with an hour commute one-way). I still go to the gym every weekday and I still can’t manage to achieve a decent sleep schedule.

Work itself is much better. Working in anime was extremely easy. There wasn’t much to do most of the time and even when there was, it wasn’t in any form challenging. Only maybe physically, when I had to drive here and there until 3am. We could come up with ideas for new projects, but the chances of any of them getting any serious attention from superiors was (is) basically zero. All that added up into a huge incentive to quit as soon as I got a chance.


The Expanse

I don’t exactly remember how I ran into The Expanse, but I ended up watching it. At this point I’m a few episodes into season 2 and I’m not exactly sure I want to see the rest.

Every review and opinion of the show mentions how the actors are horrible and the writing is great – I must have terrible taste because I am much more irritated by the story itself than by any of the actors.


ヒゲよさらば

あごひげ何年間もってたかわ正直、分からない。FBの写真を追って見ると、2012年の冬はまだ顎がつやつや(ではなかったが一応ヒゲはなかった)。そして2013年の春の写真で始めて登場して、翌年の梅雨リングを付けた。

大学の卒業式はまだとめてなかったが、会社に入って研修中にEtsyからリングを買った。

以降の3年間、そのリングでとめてあるひげがトレードマークになって、オリジン4で登場したキャラもつけてる(が、ヘルメットのせいであまり見えない)。

という長い歴を持ったひげと昨日お別れしました。イメチェンもかねて新しい可能性に挑戦していきます。


Clementine DBus changes with Ubuntu 17.04

My #nowplaying poster for Clementine stopped working with the upgrade to Ubuntu 17.04 Zesty. After short debugging with D-feet it turned out that there were some changes to the way it interacts with DBus – which is, I guess, also the reason why it can be controlled properly through the Media menu now.

However, I was (am) totally ignorant re: DBus, so figuring out how this pretty complex system worked, in one hour, still slightly tipsy, past 2am, was not exactly a simple task. Though it was still faster and easier than getting vsftpd to work properly (sober and early afternoon), as there I just gave up and apt-get purged it.


秩父行ってみた

GW中は何か、部屋にこもる以外のこともやりたくて、西武線に洗脳されて秩父行ってみた。今の時期は多分芝桜が一番の魅力かなと思うけど、俺の日帰り旅行はそんなバラ色の物語はなれなかった。

近くに池袋線の駅もあるし、一本で秩父までいけたので電車の分はまだ楽だった。よりも、行きの、電車の分がね。

何をしに行ったかって聞かれると、山を登りたかった。ググったところ、その辺はいろんな山あるし、けっこうルートとかも整ってるから、気軽にいけるかなと思った。参考にしたページに書いてあった山のなか、堂平山が一番魅力的だった。ここで第一のミス:そこでリンクされているのは東武のおすすめです。
