Mental health has been in the news quite a bit lately. Dozens of U.S. states are currently suing Meta for contributing to the youth mental health crisis by inserting addictive features into their products, while the U.S. Surgeon General is touring the nation to bring awareness to the growing epidemic of loneliness and isolation. The country has endured periods of low national morale, such as in the 1970s when high inflation and the energy crisis worsened public sentiment following the Vietnam War. The current mood, however, feels different. Gallup recently reported that national mental health is at an all-time low, with few bright spots to lift spirits. To better understand how Americans are feeling and their attitudes towards mental health in general, ThinkNow conducted a nationally representative quantitative survey of 1,500 respondents and found some interesting differences among ethnic, age and gender groups. Technology For example, 52% agree that technology and social media have a negative impact on mental health, but when broken out by race, 61% of Whites felt technology had a negative effect, and only 48% of Hispanics thought it did. While technology has helped us keep in touch with friends and family in faraway places, it appears to have degraded our ability to connect in person. Staying connected online is a double-edged sword since the same news feed that brings us pictures of the grandkids and fluffy kittens also feeds us news about the wars in Israel and Ukraine, the dysfunction in Washington, the latest mass shooting and the climate crisis. Hispanics may have a built-in defense against the isolation technology breeds, owing to their large, multigenerational households, strong social support systems, and tendency to use social media to stay connected with relatives abroad. Age and Gender When asked how individuals rate their mental health, men rate it higher than women by 11 percentage points, and Baby Boomers rank it highest at 83%, saying it’s good or excellent vs. 57% of Gen Z saying the same. Gen Z spends the most amount of time on social media, so the notion that social media negatively affects mental health appears to be correlated. Unfortunately, Gen Z is also the generation that’s least comfortable discussing mental health concerns with healthcare professionals. Only 40% of them state they’re comfortable discussing their issues with a professional compared to 60% of Millennials and 65% of Boomers. Race Affects Attitudes As seen in previous research conducted by ThinkNow, Asian Americans lag other groups when it comes to awareness of mental health issues. Twenty-four percent of Asian Americans believe that having a mental health issue is a sign of weakness compared to the 16% average for all groups. Asians are also considerably less likely to be aware of mental health services in their communities (42% vs. 55%) and most likely to seek out information on social media (51% vs. 35%).

From their humble beginnings in 1984, TED has grown into the world’s most powerful amplifier for speakers and thought-leaders to share their ideas. They have over 2,400 filmed talks (not including the 30,000+ TEDx videos) freely available online, and have hosted over 17,500 events around the world. With over one billion views in a year, it’s no wonder that so many speakers are looking to TED for ideas on how to share their message more effectively. The article “5 Public-Speaking Tips TED Gives Its Speakers”, by Carmine Gallo for Forbes, gives speakers five practical ways to connect with their audience, and effectively share their ideas on stage. Whether you are gearing up to get on a TED stage yourself, or just want to master the skills that so many of their speakers possess, these tips and quotes from Chris Anderson, the TED Talks Curator, will encourage you to make the most impactful impression on your audience.

当然すぎる話ですが 暗黒の時代を 踏まえつつの今です

気合いではじまった スタートアップが 抱える問題と向き合う 時期
35.
36.
抱える問題 • 創業以来継ぎ足されてきた秘伝のソース • PHPにベタ書きされている設定情報 •
ガン無視されてるエラーログ
37.
とりあえず何とか 見えるようにしましょう Nagios Monit cloud watch retty.me 37
38.
計測されない事は 改善されません • とにかく見えるようにしましょう • DUPLICATE,
WARNとはとにかく共有 • EX:Nagios
39.
あえて残した問題 • スケールアウト戦略 • duplicateな実行環境 •
EX:PHP5.3, MySQL5.5
40.
問題無かったこと • 社内インフラ?なにそれ美味しいの? • 情報共有? •
知らなくていい事まで知ってる
41.
恵比寿 (会社っぽくなる) 41

43.
サービスのインフラと PHP環境が最も 進化した時期
44.
いよいよ どうにもならなく なってきたとも言う
45.
フェーズに応じた 適切なアップデート 時期
46.
サービスの問題 • 全然スケールしないアプリケーションサーバと DB • duplicateしまくりなPHP環境 •
中身が全然わからないami
47.
対策
48.
ミドルウェアアップデート • 32bit ->
64bit (INT_MAXにはまる) • PHP5.3 -> PHP5.5 • MySQL5.5 -> 5.6
49.
マネージドサービスの 本格運用 • ElasticBeanstalkでPHP実行環境を宣言的に • RDSによるボトルネック処理のスケールアウト 戦略 •
ElCache, CloudFront有効活用
50.
PHPerとして AWSを使い倒すために 重要なこと
51.
とにかく自前で プロビジョニングとか 出来るだけやらない
52.
CloudFront RDS EC2 ELB EB S3 retty.me RDS EC2 ELB RDS EC2 ELB Nginx Nginx EMR MongoDB ELC memcached ELC Redis Route 53 52
53.
社内インフラの問題 • 人員増えまくりなのにバッファ⚪ーのルータ • ネイティブアプリの開発環境問題 •
ルーティングで色々解決したい
54.
対策
55.
社内インフラ整備 • RTX-1200系導入 ->
お約束 • NATテーブルが れる。あるある。 • 社内DNSとVLAN搭載APでそこそこなルーティング • MacMiniとELECOMの組み合わせがリーズナブル
56.
情報共有の問題 • なんかskype限界 • フリーのチャットツール色々使ったけどうま くいかない •
GoogleDocsの限界
57.
対策
58.
情報共有改善 • HipChat, ChatWork,Slack比較
-> Slack • Qiita:Team -> ポエムからはじめる • Hubot -> タスクのbot化

立ちはだかるオフィス 移転
62.
立ちはだかるオフィス移転 • 引っ越し対応死ねる • LANケーブル配置確認 •
スイッチ売ってくれ -> サーバも買いませんか?
63.
立ちはだかるオフィス移転 • APの自動切り替え(初の2フロア) • ゲストネットワークの隔離 •
APの可用性、拡張性
64.
• VPNが不調です ->
うるせー! • DNSサーバ不調です -> うるせー! • ネット回線が不調です -> うるせー! 立ちはだかるオフィス移転
65.
対策
66.
物理で殴る • インテリジェントなL3W(dell) • 業務用AP(ArubaのOEM) •
VPNルーター(RTX-1210) * 2
67.
物理で殴る • MacMini • 12Uラック •
シリアルインターフェース(ケーブルとか windowsとか)
68.
69.
気がついたら こうなってた
70.
出来れば経験アリの フリーランスさんが いると頼もしい
71.
金額が見合えば 委託 も十分あり
72.
サービスインフラの 健全化
73.
健全化 • Classicとの決別 • あらゆる状態の可視化 •
率先した情報共有
74.
Classicとの決別 • 新世代インスタンス不可 • 内部DNS(Route53)使用不可 •
InternalELB不可
75.
他にも上げればキリが 無いです
76.
とにかく ClassicがDupliate なのは明白
77.
78.
移行のポイント
79.
qiitaから転載
80.
状態の可視化 • NewRelic • Mackerel
81.
82.
83.
併用がおすすめ
84.
監視のレイヤー プロセス リソース ロール分 レスポンスタイム アプリケーションエラー ボトルネック処理 Mackerel NewRelic
85.
Tips • NewRelicは割と高いのでleader_onlyがオスス メ • Multi-Zoneで配置位はやってもいいか •
mackerelは用途と金額から全台いれるのがオスス メ
86.
「見える」 を 「残す」
87.
率先した情報共有
88.
障害報告から始めてみる • 情報は資産です • あなたが知ってる事はあなたが思ってる以上に 価値があります •
変な吊るし上げをする人は全力で駆逐すべし
89.
まとめ
90.
まとめ • サービスインフラはあらゆる状況を可視化する • 社内インフラも「共有」という名の元に状態を 可視化 •
情報は一箇所に、権限無く集めて可視化
91.
今ある仕組みは 誰かが試行錯誤した 結果
92.
否定して変えよう とすると 大抵失敗します
93.
体験談
94.
見えるようにさえなって れば誰かが勝手に 直そうとしてくれます
95.
チームが進むための 情報を見えようにする のがRettyのDevOps
