[Linux] cross compile tmux for Synology DS216play via DSM 6.1 Tool Chains - STMicroelectronics Monaco Linux 3.10.102 @ Ubuntu 16.04 64bit

連假最後一天跑來把玩一下 cross compiler ，想說未來應該會越來越常用 NAS 做事，覺得裡頭沒有個 tmux/screen 很煩，然而，等了很久還是沒人為 DS216play 編譯 tmux ，一直很搞不懂，直到我翻了這張表出來：

https://www.synology.com/en-global/knowledgebase/DSM/tutorial/General/What_kind_of_CPU_does_my_NAS_have

System Model CPU Model Cores Threads FPU Package Arch RAM
DS216play STM STiH412 Dual Core 2 Yes Monaco DDR3 1 GB

好的，看起來有點冷門的 STM STiH412/Monaco 囧，不過找一些討論串才知道，由於要讓 DS216play 可以做一些多媒體影音的事，所以，就別抱怨了 XD

收工

ASUS X556U 更換 SSD 筆記

前幾天室友的 ACER 4810TZG 掛了，於是乎人生中第二台 ASUS 的筆電入手，找了許久不想買太舊也不想買太新，就挑了個接近兩萬且大螢幕的 ASUS X556U ，其特色是 CPU 是 i5-6198UD 吧，看起來不差勁 XD 可惜預設是 HDD 就真的悲劇了點，按了電源後到進入 Windows 10 桌面，大概要 3-5 分鐘吧，所以，讓我想把舊筆電的 120GB SSD 拿來頂用，果然效果奇佳，開機就不到 10 秒進入到 Windows 10 桌面。筆記一下做了哪些事：

首先，是下載 Windows 10 ISO 並製作成 USB 開機碟，找了良久，原來當年可以從微軟官網透過簡單的 JS Code 可下載各種版本的 Windows ISO 的部分已被拿掉，但在 macOS 環境上還是可以輕鬆下載 ISO - https://www.microsoft.com/zh-tw/software-download/windows10ISO， 而在 Windows 上會被引導下載 MediaCreationTool.exe 工具，就透過 MediaCreationTool.exe 引導而製作 USB 開機碟。

如此一來，就只剩下換掉硬碟的部分，先上網隨便找個 ASUS 筆電看一下，才知道換硬碟真麻煩，主因是螺絲有一個躲在墊子下方，而就算所有螺絲都弄下來，拆殼還是很麻煩 Orz 後來，某天晚上終於牙一咬動手了



先拆座墊！在拆記憶體旁的螺絲，就開始用一字慢慢橇開背殼，自己手工很差，所以都會有刮傷，反正自用啦 XD



如此一來，就看到硬碟所在之處，在拆兩個螺絲、拆掉兩邊排線後，再把旁邊的小板拿起來就可換硬碟了！

[macOS] m3u/m3u8 -> grep -> xargs -> wget -> ffmpeg: ts -> mp4

目的是把 m3u8 的資料備份，接著又覺得檔案一堆，不如就用 ffmepg 轉 mp4 ，久久用一次，又忘得差不多。

連續動作：

$ wget http://.../index.m3u8 -O index.m3u8
$ grep -v "#" index.m3u8 | xargs wget
$ vim index.m3u8
:%s/http[^\/]+//g
:%s/?.*//g
$ grep -v "#" index.m3u8 | tr -d '\r' | awk '{cmd="mv "$1"* "$1; print cmd}'
$ grep -v "#" index.m3u8 | tr -d '\r' | awk '{cmd="mv "$1"* "$1; system(cmd)}'
$ ffmpeg -i index.m3u8 -vcodec copy -acodec copy -bsf:a aac_adtstoasc out.mp4

[PHP] 使用 AWS SDK 進行 S3 檔案上傳

寫過又忘了，筆記一下，環境是 PHP 5.5.9：

<?php
require 'aws.phar'; // http://docs.aws.amazon.com/aws-sdk-php/v3/download/aws.phar //aws-3.27.5.phar
$s3 = Aws\S3\S3Client::factory(array(
'region' => 'us-west-2',
// http://docs.aws.amazon.com/aws-sdk-php/v3/api/index.html
'version' => '2006-03-01',
'credentials' => array(
'key' => 'key',
'secret' => 'secret',
),
        ));

try {
$result = $s3->putObject(array(
'Bucket' => 'my-bucket',
'Key' => 'my-object-key'
'SourceFile' => $_FILES['userfile']['tmp_name'],
        ));
} catch (Exception $e) {
             
echo $e->getMessage() . "\n";
}

print_r($result);
// $result['ObjectURL'];

                )

            [ObjectURL] => https://s3-us-west-2.amazonaws.com/my-bucket/my-object-key
        )

)

[PHP] 使用 SimpleXML 處理 RSS 資料

以前寫過，又忘又沒筆記 Orz

連續動作：

$ch = curl_init();
curl_setopt($ch , CURLOPT_URL, 'https://YourSite/rss');
curl_setopt($ch , CURLOPT_RETURNTRANSFER , true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

$result = curl_exec($ch);

$output = array();
$xml = @simplexml_load_string($result);

if (isset($xml->channel) && isset($xml->channel->item)) {
foreach($xml->channel->item as $item) {
$date = date_parse((string)$item->pubDate);
array_push($output, array(
'date' => date('Ymd', mktime(0, 0, 0, $date['month'], $date['day'], $date['year'])),
'title' => (string)$item->title,
'link' => (string)$item->link,
'content' => (string)$item->children('http://purl.org/rss/1.0/modules/content/')->encoded,
'thumbnail' => null,
));
}
}
