３つの指標

鳥のさえずり声を聞いて、私は悪態を吐いた。今日の早朝に予定されていたミーティングのことをすっかり忘れていたのだ。 まったく、最悪の朝だ。着替えている間に、電話も鳴った。「高い金を払ってコンサルタントを雇った極めて重要なミーティングだ」と念を押されていたというのに。 それもこれも昨日のバグのせいだ。睡眠時間も、開発スキルも、人員も、私の現場には何もかもが足りていない。 それにも関らず、理解の足りない上司は「テスト工程を削ってでも早く納品しろ」とプレッシャーを与えてくる。 あの馬鹿どもめ。一体何を考えているんだ？

For a safe and fast Erlang SSL server, there's a few 
configuration values you might want by default:

    [{ciphers, CipherList},      % see below
     {honor_cipher_order, true}, % pick the server-defined order of ciphers
     {secure_renegotiate, true}, % prevent renegotiation hijacks
     {client_renegotiation, false}, % prevent clients DoSing w/ renegs
     {versions, ['tlsv1.2', 'tlsv1.1']}, % add tlsv1 if you must

TIL how to make deprecation warnings:

Compiling 2 files (.ex)
warning: `Retort.Resources.timeout/2` is deprecated; call `Retort.Resources.Timeout.get_or_default/2` instead.
  lib/retort/resources.ex:197: Retort.Resources.timeout/2

Replace function

WannaCry|WannaDecrypt0r NSA-Cyberweapon-Powered Ransomware Worm

• Virus Name: WannaCrypt, WannaCry, WanaCrypt0r, WCrypt, WCRY
• Vector: All Windows versions before Windows 10 are vulnerable if not patched for MS-17-010. It uses EternalBlue MS17-010 to propagate.
• Ransom: between $300 to $600. There is code to 'rm' (delete) files in the virus. Seems to reset if the virus crashes.
• Backdooring: The worm loops through every RDP session on a system to run the ransomware as that user. It also installs the DOUBLEPULSAR backdoor. It corrupts shadow volumes to make recovery harder. (source: malwarebytes)
• Kill switch: If the website www.iuqerfsodp9ifjaposdfjhgosurijfaewrwergwea.com is up the virus exits instead of infecting the host. (source: malwarebytes). This domain has been sinkholed, stopping the spread of the worm.
