イベントログを触ってみる

C#

日々社畜業に勤しんでいると、月にどのくらい社畜しているか気になるものです。
社畜の嗜みとして勤務時間の記録はきちんとしておきたいものですが、よく記録するの忘れます。
数日程度忘れます。
PCついてる時間≒勤務時間ということでまとめてイベントログから拾えばいいんじゃ？ということで。

今インストールされているOpenSSLがビルドされた時のあんな事やこんな事を確認する

OpenSSL

Heartbleed Bugとか、CCS Injection Vulnerabilityとかあって調べたのでめも。

本家マニュアルはこちらです。

使ってみる

"-f"オプションで確認できます。

$ openssl version -f

プログラミング生放送勉強会 第29回＠サイボウズ株式会社 松山オフィス #pronama 突撃してきました。

勉強会 プロ生

6/14日(土)に行われた「プログラミング生放送勉強会 第29回＠サイボウズ株式会社 松山オフィス」に参加してきました。

一言。
プロ生ちゃんマジ天使！

参加の動機のようなもの

主にだるやなぎ氏のコンテンツ力に影響されました。
3月後半ぐらいの私のTLをさかのぼると出てくると思いますが、とにかくノープランでえいやと参加ボタンを押したのは仕方のないことだと思います。

セッション*1

LT*2

懇親会

周囲を猛者達に固められて小さくなっておりました。
がりっち氏とお話できました。Global Windows Azure Boot Camp 2014 in Japan!!の時からロックオンされていた模様。

参加します!!

6/21 CLR/H+プログラミング生放送勉強会＠GMO Yours
相変わらずノリと勢いですが、懇親会のときに参加を決定しました。
皆さまよろしくお願いします。

Debian(squeeze)無線LAN環境の構築

Debian(squeeze)で無線LANを使うまでの作業メモ。
今回、魔が差して有線LANに接続せずに環境を構築してみた。

BUFFALOのページからWindows2000用ドライバをダウンロード・インストール。

#ndiswrapper -i netamg54.inf


インストール状況を確認。

#ndiswrapper -l
netamg54 : driver installed
device (168C:0013) present (alternate driver: ath5k)

#depmod -a

#modprobe ndiswrapper
FATAL: Module ndiswrapper not found.

ndiswrapperのモジュールが無いらしい。

DVDを挿入。
モジュールをビルドする。

#module-assistant prepare
#module-assistant a-i ndiswrapper

今度は通ります。

#modprobe ndiswrapper

自動起動ファイルの生成と起動時にロードする設定。

#ndiswrapper -m
#echo "ndiswrapper" >> /etc/modules

私の無線LAN環境はWPA2PSK(TKIP)なので、wpa_supplicantをインストール

#dpkg -i wpasupplicant_0.6.10-2.1_i386.deb

wpa_supplicant.confを生成

#wpa_passphrase myid mypass > /etc/wpa_supplicant/wpa_supplicant.conf

network={
ssid="myid"
scan_ssid=1
proto=RSN
key_mgmt=WPA-PSK
pairwise=TKIP
group=TKIP
psk=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
}

/etc/network/interfacesを編集

iface wlan0 inet dhcp
wpa-essid "myid"
wpa-driver wext
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

接続てすと

#ifup wlan0
