Writing whatever I want
While I'm sure that switching away from the use of words like "blacklist" will not do anything regarding racial equality, but since we're at it, can't we choose a less ambiguous alternative?
The current alternatives like "allowlist", "trusted list", "blocklist", "denylist" all have alternative connotations and can not be replaced one-to-one.
Therefore, I propose the terms "greenlist" and "redlist".
Even though the official sites and notices in stations are all trying to convince you that there is no way you can buy a PASMO and Suica right now, scaring all visitors without iPhones away, there are still ways you can buy one now.
This is the officially recommended way, even though they are sold in just a few locations. Also, they expire after 28 days and you cannot refund the unused charged money inside, so I personally do not recommend this. For those working and studying, this is basically useless. You can check out their official sites for where you can still buy them: PASMO PASSPORT, Welcome Suica
As JR did not announce this at all and just secretly updated their visitor-facing website, it got very little media attention. I went to ask the staff a while ago, and I was told that even though they are intended only for tourists, they will not check for documents like passports. This is probably your best bet if you happen to be in one of the stations. Check this link out: JR East Travel Service Center.
This approach has the obvious benefit that it can be bought in basically every single JR station. Even though the official website mentioned that only children and monthly pass Suica are still sold, 1-day passes can also be issued on a new Suica. So if your trip has a day where using a one-day JR pass is beneficial (if you live in the west side like Nakano, a round-trip to Kasai Rinkai Park is already worth the cost of the Tokunai Pass!), go to a black ticket machine (that sells monthly pass), and choose the option that issues a new Suica. Check the following video but choose the new Suica option instead!
雖然官方網站和車站各處還是都是標貼 Suica 和 PASMO 停售的通告，對沒有 iPhone 或日本 Android 手機的人很是嚇人，但是大家也知道是有辦法的。在本文我想總結一下已知的購買交通系IC卡的方法和已經失效的方法，其中購買 PASMO 的方法更是不見有人提起，而且昨天（2月24日）親身測試成功！
專為遊客推出的 Welcome Suica 和 PASMO PASSPORT 是官方建議的方式，但28天後就失效而且不能退餘額非常麻煩，對來日本留學工作的人也毫無用處。但是適合的話可以參考以下連結：PASMO PASSPORT、Welcome Suica
因為JR方面非常神秘，只是偷偷更新了旅客網站，因此只有很少網站有提起。據本人到現場的詢問，雖然理論上只能讓遊客購買，但是不會檢查護照等文件，但是只能購買一張。但是能購買的地方只有幾個，還是有點麻煩。可以參考以下連結：JR東日本旅行服務中心。
雖然官方通告提起只有兒童和「定期票」（即月票）還有繼續發行 Suica，但是一日乘車票等卻沒有提起，但其實是包括的。所以如果有一天行程有適合的 JR 一日券（760yen可以任意乘搭JR在東京23區的路線很划算啊！如果住西面的話來回一次葛西臨海公園就已經超過回本了），就可以在車站用黑色（能買定期券）售票機，選擇購買一日票然後選擇發行新的 Suica。用法可以參考以下影片，但是到選擇是否用原本的 Suica 的時候要選擇新Suica！
有些人可能因各種原因（好看？想買京王+東京Metro一日券？）想買 PASMO 而不要 Suica。原理與 Suica 一日券相同，方法也差不多。但是不同的是 PASMO 有很多使用的公司，而有些公司的售票機可能不賣 PASMO，而每間公司的界面也有點不同。

原本考慮到輕軌公司在2019年是剛成立，可能有其他更重要的工作而無暇兼顧這些小事（雖然明明可以讓港鐵澳門協助設計，港鐵澳門設計的各種標識和單張明顯好看很多）。但是現在已經又過了4年，其中還包括停運半年修復電纜和疫情時期極少人乘搭的兩年，甚至連延伸至媽閣站，必須更新系統的大好機會仍不肯改個稍爲好看一點點的設計（就算只是改個好看點的字體已經很棒了）。但是考慮到未來可能很快就要連通石排灣和橫琴站，可能到時候再大改，我又再忍了下來。
直到我今天無意中看到2012年輕軌1:1列車模型展覽，當中的界面設計竟然和現在的一模一樣以後，我是無法再忍下去了。
當年只是爲了示範而隨便設計個畫面固然沒有問題，但是相信沒有人認爲這樣子的設計是在正經的運營路線上是可以接受的吧？！
具體問題我就不說了，有點審美意識的一眼就已經能看出好幾個問題。
所以輕軌公司是要有多懶？反正我是忍不了了，就希望明年港鐵退場、兩線通車之前能請港鐵搞搞吧。。。
My YouTube Home feed has more than 50% of the videos from channels I'm not even subscribed to, while many subscribed channels simply do not appear on my feed.
The shift in recent years in social media from "telling the system what you like" to "system telling you what you like" is troublesome. The fact is we know what we want, and not watching a certain channel for a few weeks doesn't mean we will never want to watch it (that's what the Unlike or Unsubscribe button is for!).
I argue that there are two types of content that one watches: funny, quick, one-off content, and actually interesting, lengthy, in-depth content. Examples of the former includes (and these are directly from my YouTube feed right now) Microsoft Sam Beatbox Duet, 1996 Pontiac Grand Pix Recall: interesting for when you are relaxing, but I basically don't want to see anything like it anymore after watching it. Examples of the latter would be: The Impact of 6GHz on Network Design, PS5 Slim First Look and TEARDOWN!!, or I Visited the Most Depressing Town in Singapore.
Suggesting new content is great to help discover new channels and give visibility to new creators, but there is a limit to it: there is a reason a user decide to subscribe to a channel instead of just watching it and leave, and since the algorithm does not know how the user liked it or not (who cares about the like button anymore??), it is idiotic to suggest this much new content to a user just because the user fell for two clickbaity videos two times in a row.
Going back to the two types of content. Please, only ever suggest a few of the first type, and never the same topic over and over. For the second type, please, prioritize what we literally said we liked, instead of filling my entire feed with train videos (yes I like trains, but I also like many other things that I literally told the algorithm by subscribing).
Thanks for listening. After seeing the 20th Burger King Pokeball recall advertisement parody being suggested just because a few weeks ago I felt bored and watched a few in a row, I decided that I have to write something about this.
原本載於維基百科思源黑體條目，但因屬原創研究並沒有關注度而被刪除，會再看看有沒有可信新聞來源支持重新加入，但肯定會大幅削減，故發佈在此。
Continue reading "思源黑體的衍生字體"As you might know, I live in Canada while my home server is located in Macau. Both sides have decent internet connection: 150Mbps symmetrical in Macau, 350/100Mbps in Canada. While not crazy fast, this is fast enough for most cases, even for transferring large files. But there is a problem: I can never get this speed...
The problem is simple: I can download from my home server somehow close to the limit (150Mbps) but I can only upload at less than 10% of theoretical upload speed, seemingly for no reason.
I tried running speedtest from Canada to different hosts in Macau: different ISPs, my server with LibreSpeed, my server with iperf. I found that I only get good speeds when I use multiple connections: multi connection feature on Speedtest.net, iperf with LOTS of parallel streams.

在此向 Radio Mobile 開發者 Roger Coude (VE2DBE)、全球地形圖 ALOS World 3D-30m (AW3D30) 提供者日本宇宙航空研究開發機構 (JAXA) 及 OpenStreetMap 貢獻者致謝。
紅色代表信號最好，橙色黃色其次，綠藍等顏色則代表信號非常差。

上文説到澳門公天公司仍有使用的電視頻道來源，例如是使用魚骨天線接收香港和深圳的信號或是使用衞星天線（衞星獲）接收沒有加密的電視台。不過年紀較大的讀者應該會記得十幾年前電視機是能看到更多的電視台的，而且內容亦更豐富精彩，例如我家人愛看的好萊塢電影台和中天新聞。這些電視台的信號是從何而來？這篇文章將會為你帶來答案。
簡單來説，這些頻道全都是透過衞星傳送，並且是有加密的（上文所述的開鎖衞星台則是沒有加密）。在2012年前，澳門法律並沒有把擅自破解加密的行為視為違法，需由版權方提出投訴後才構成侵權行為。而這些頻道正是「2012年前存在，雖然是破解獲得，但由於版權方沒有投訴因此可以保留」而成的。
