Team USA Commentary Roundup!

In honor of Independence Day, here’s a listing of all my commentary videos for Team USA!

A Short Incursion Into Alternate Hadoop Filesystems

Steve Loughran starts with a critical look at Netapp Open solution for Hadoop paper:

Actually it is weirder than I first thought. This is still HDFS, just running on more expensive hardware. You get the (current) HDFS limitations: no native filesystem mounting, a namenode to care about, security on a par with NFS, without the cost savings of pure-SATA-no-licensing-fees. Instead you have to use RAID everywhere, which not only bumps up your cost of storage, puts you at risk of RAID controller failure and errors in the OS drivers for those controller (hence their strict rules about which Linux releases to trust). If you do follow their recommendations and rely on hardware for data integrity, you’ve cut down the probability of node-local job execution, so all FUD about replication traffic is now moot as at least 1/3 more of your tasks will be running remote -possibly even with the Fair Scheduler, which waits for a bit to see if a local slot becomes free. What they are doing then is adding some HA hardware underneath a filesystem that is designed to give strong availability out of medium availability hardware. I have seen such a design before, and thought it sucked then too.  Information week says this is a response to EMC, but it looks more like NetApp’s strategy to stay relevant, and Cloudera are partnering with them as NetApp offered them money and if it sells into more “enterprise customers” then why not? With the extra hardware costs of NetApp the cloudera licenses will look better value, and clearly both NetApp and their customers are in need of the hand-holding that Cloudera can offer.

Then in a follow up post, he looks at a couple of alternatives (Lustre, GPFS, IBRIX, etc):

I’m not against running MapReduce—or the entire Hadoop stack—against alternate filesystems. There are some good cases where it makes sense. Other filesystems offer security, NFS mounting, the ability to be used by other applications and other features. HDFS is designed to scale well on “commodity” hardware, (where servers containing Xeon E5 series parts with 64GB RAM, 10GbE and 8-12 SFF HDDs are considered a subset of “commodity”).

2014 GPF Barcelona - Julia Lipnitskaia SP (Megapolis)

Canadian ice dance x red

Happy Canada Day!

triple-axel said: Hanyu for sure. Patrick Chan doesn’t stand a chance. Yuzuru’s improved so greatly, and there’s no way Patrick will beat the quad in the second half. He may beat him with PCS (I doubt it but maybe), but Yuzu has him technically, as usual.

Hmm, I don’t know about that… I expect it to be close between them, and I’m not sure who’ll be first. Maybe, like, one of them wins the GPF, the other one wins the 4CC and then whoever’s cleaner wins Worlds. I’m curious about this rivalry but I reaaally doubt Patrick “doesn’t stand a chance”. He does, big time. If he wins all most important events next season - I won’t be surprised in the slightest.

It’ll also be very interesting to see where everyone else stand in this situation - Fernandez, Ten et al.

Yes, it took THIS long before the major time travel stuff. In a Homestuck fan fic.

“Hey hey hey motherfucker, It’s fat Albert.” “How did you afford that shit?” “Just making a little ‘truce’ to build a hot air balloon with a 'fight’ that has the promise that the winner takes the balloon.”

(Yeah that image is supposed to be of the Time Screwer, and the hands on the clock are supposed to be pointing to about 6:16.)

Chapter 21 is out!

Once again I don’t really have anything to say about the chapter itself and I half-assed the image, so let me say something that might be a bit controversal. But hey, if you’ve made it this far into HHC (basically the final boss of my writing as it stands) where it regularly kinda insults a lot of things, this is probably nothing:

I think I’ve been kinda turning HHC into what I’ve feel is a nail-on with the problems I have with recent Adventure Time. I mean, I’d still watch it if there’s a new episode because hey I often find myself needing to kill off quarter-hours and find ways to procrastinate my writing, but it’s still… lacking. In the post for chapter 19 I basically said that I don’t like it should some serious that previously had good emotional-related character development and a nicely fleshed out world would sacrifice things like that in favor for trying to make “the most overpowered asshole villain ever.” Obviously that isn’t my problem with Adventure Time since it’s not even an issue, it still has a large world and as of the end of season six there doesn’t seem to be a real “Lord English” of the story where we’re being repeatedly hyped about an antagonist I have very little care for. I feel like its main fault is that’s bad at taking itself seriously (while Steven Universe, on the other hand, absolutely accels with this). Even back in that Mortal-Recoil two parter thing with the Lich (I’m typing this almost completely out of memory here, not looking up the titles right this moment) I found that to be one of the weaker earlier episodes because throughout most of it I found it boring. I can’t really explain why off the top of my head nor do I even feel like trying to right now since I’d just like to get all the HHC-related stuff out of the way during these publish days, so I’ll skip over that point entirely and just get to why HHC is sorta going off that. Basically I feel that while there is a large and linking plot within AT getting the pieces for it often involves a considerably less interesting episode, especially those that are centered around one or two-dimensional nobodies that aren’t made too interesting. And HHC is now kinda been pushed to go in a similar direction: There will be an extremely large and complicated creation myth, but not one worth getting through all the lines and lines of text and relationship drama between John, Jade, and I guess Rose or others to reach it.

I don’t know. I’ll think of looking this over and reorganizing my thoughts a bit to make this more conherant.

14-15シーズンを終えて

14-15シーズンが終わりましたね。
みなさんお疲れ様でした。
スケーターさんも応援するファンの方達も、今シーズンはまさに「激動」のシーズンだったと思います。

・結弦さん腰痛によりフィン杯欠場
・崇彦さん大遭難、躍進を予感させた知子ちゃんのJO
・極北
・スケカナ無良くん優勝
・CoC結弦さんとハンヤンちゃんの事故
・ロステレ理華ちゃん初優勝
・N杯ダイスくん初優勝
・GPF結弦さん2連覇達成
・崇彦さん全日本で復活のフリー
・全日本女子は鬼採点で大波乱
・結弦さん手術
・樹くん突然の引退
・無良くん両足捻挫
・結弦さん知子ちゃんワールド銀メダル
・男子の来季(もう今季)の枠は2

ざっと書き出してみましたがこれはすごい。ここに昌磨くん草太くんJrGPF金銀とかJrワールド金銅とか、新葉ちゃんJrGPF、Jrワールド銅メダルとかも加わるわけだ。

ソチでフィギュアスケートという競技にハマりもう1年半が経ちましたが、まさかハマって初めてのシーズンがこうも凄まじいとは。平昌シーズンに向けていい心構えにはなったかな。

CoCのあの事故ももう7ヶ月前のことなんですね。あの時はただ目の前で起こったことが信じられなくて、Twitterとテレビの画面を交互に見て、2人の無事をずっと祈っていました。あのときのフリーはまだ見返せていないです。いつかもう1度ちゃんと見れたら、私の中であの事故はきちんと昇華できると思う。

私の中で今シーズン一番心に残った選手はやっぱり崇彦さん。崇彦さんは見てて本当にもどかしかったです。崇彦さんはスケートにはまる前から好きだったので余計に辛かった。「絶対もっと出来るのに」と思いながら見てました。
だからこそ全日本のあのフリーは嬉しかったし、あの場に観客として立ち会えたことが本当に幸せに思います。
ワールドは残念な結果になってしまったけど、「もう一度表彰台に立つ」という思いで挑んでくれたのが嬉しかったのです。インスタの「飛びます、跳びます。」というコメントは正直キました。最後まで諦めないで跳んでくれて、ありがとう。


そして結弦さん。

結弦さんは世間からはもはや聖人君子のように言われているけど、色々なことを経て、いい意味で人間らしさや泥臭さのようなものを見れた気がします。
結弦さんだって生身の人間で、痛いところだってたくさんあって、いつでもジャンプを完璧に決められるなんてことはなくて、だけどそれに一番腹を立てているのは多分彼で。
「4回転は跳べて当然のジャンプ」
そう発言した結弦さんの14-15シーズンの4回転の確率はおそらく50%を切ってます。当たり前が当たり前じゃなくなったとき、どんな思いをしたか。それは彼にしかわかりませんが、きっと苦しかったことだと思います。

国別では笑顔をたくさん見せてくれましたが、完璧な演技ではなかった分(ファンからすれば十分ですが)、内心メラメラでしょうし、またこの悔しさを今シーズンにぶつけてくれればいいと思います。でもステイヘルシーで!!!!!!


あっという間に過ぎ去った14-15シーズン。気づけば平昌まであと2年半。
今シーズンもきっとわくわくハラハラドキドキして、胃を痛めて手を組んで必死に祈って、神演技でも迷走しても泣いて、そんな風に過ぎていくんだろうな。

とにかく今を楽しんで。
大好きなスケーターさんが大好きなスケートを続けられることに感謝して。
今シーズンもみんな元気に神演技を祈りたいと思います!
