日本如何庆祝五一劳动节?
日本劳动运动史入门
~“全国总工会”们的爱恨情仇~

时间:2025年4月28日(一) 19:00-21:30
地点:新宿区四谷地域中心 集会室4(线上:jitsi会议链接将在活动开始前10分钟在IG主页发布)
语言:日文分享+中文翻译
参加费:500日元+随喜

五一劳动节将至,不知道朋友们有没有发现,东京有三个“全国总工会”(連合/全労連/全労協)各自组织了自己的五一劳动节集会。
充满好奇心/对日本社运颇感兴趣/在日本当或可能要当劳动者的你或许会想知道:
• 它们之间有什么区别?为什么日本会有三个不同的“全国总工会”(National Center)?
• 它们各自的特点是什么?在做什么样的活动?如何维护劳动者的利益?
• 五一劳动节对于劳动运动和工会来说有何意义?为什么五一劳动节集会不止关注劳动问题?

我们邀请了专修大学教授兵头淳史老师,为大家解答上述疑问。动身去参加属于你的五一劳动节集会吧!

ディビジョン2(ゲーム)に登場するISAC(アイザック / Intelligent System Analytic Computer / インテリジェントシステム分析コンピュータ)というAIがある。

単独行動する主人公たちエージェントを携行する装置とバックエンドの衛星ネットワークで支援し、天候から敵の情報、エージェント自身のバイタル情報、各種システムへ接続して分析・ハッキングなどを行う重要な戦略兵器なのだが、それはまあおいといて、

本当は人間のように思考して流暢な言葉で声を掛けたりできるシステムとして開発されているんだけど、これを敢えてアナウンスや分析結果の報告のみ機械的に回答するように制限しているのね。これは納入先の政府側の要望・判断によってそうなったという。

開発者たちの会話によると「人間は、まだチューリングテストにパスするAIを受け入れられないんだよ」などと言っているわけ。

そうか……。

一方、ANNAという……(以下オタク語りなので割愛)

本日発売のSFマガジン2025年6月号に短編「ミッドナイト・イン・トロカデロ」が掲載されています。今回も扉絵は紙谷俊平様に描いていただきました。今回もめちゃ素敵ですのでお楽しみに。あと私の推し=セザール・フランク=作曲家が扉絵に描かれることって多分もう二度とないやつだと思います。うれしい…

With bluesky (mostly) going down for a few hours today, I got to wondering about how decentralized the fediverse really is in terms of where its servers are hosted. I grabbed a server list from fedidb, with network information coming from ipinfo.io .

[EDIT: I did a better analysis on a dataset of 10x as many servers, see discuss.systems/@ricci/1144003 ]

These stats are by the number of *servers* not the number of *users* (maybe I'll run those stats later).

fedidb currently tracks 2,650 servers of various types (Mastodon, pixelfed, lemmy, misskey, peertube, etc)

The fediverse is most vulnerable to disruptions at CloudFlare: 24% of Fediverse servers are behind it. Also note that this means that I don't have real data on where this 24% are located or hosted, since CloudFlare obscures this by design.

Beyond CloudFlare, the fediverse is not too concentrated on any one network. The most popular host, Hertzner, only hosts 14% of fediverse servers, and it falls off fast from there.

Here are the top networks where fediverse servers are hosted:

504 Cloudflare, Inc.
356 Hetzner Online GmbH
130 DigitalOcean, LLC
114 OVH SAS
56 netcup GmbH
55 Amazon.com, Inc.
55 Akamai Connected Cloud
36 Contabo GmbH
33 SAKURA Internet Inc.
32 The Constant Company, LLC
31 Xserver Inc.
28 SCALEWAY S.A.S.
24 Google LLC
23 Oracle Corporation
16 GMO Internet Group, Inc.
14 IONOS SE
14 FranTech Solutions
11 Hostinger International Limited
10 Nubes, LLC

Half of fediverse servers are on networks that host 50 or fewer servers - that's pretty good for resiliency.

There is even more diversity when it comes to BGP prefixes, which is good for resiliency: for example, the cloud providers that have multiple availability zones will generally have them on different prefixes, so this gets closer to giving us a picture of the specific bits of infrastructure the fediverse relies on.

The top BGP prefixes:

55 104.21.48.0/20
50 104.21.16.0/20
48 104.21.64.0/20
41 104.21.32.0/20
41 104.21.0.0/20
38 104.21.80.0/20
32 172.67.128.0/20
31 172.67.144.0/20
28 172.67.208.0/20
28 162.43.0.0/17
27 104.26.0.0/20
26 172.67.192.0/20
26 172.67.176.0/20
23 172.67.160.0/20
19 116.203.0.0/16
17 172.67.64.0/20
17 159.69.0.0/16
16 65.109.0.0/16
14 88.99.0.0/16
14 49.13.0.0/16
13 78.46.0.0/15
13 167.235.0.0/16
13 138.201.0.0/16
11 95.217.0.0/16
11 95.216.0.0/16
11 49.12.0.0/16
11 135.181.0.0/16
10 37.27.0.0/16
10 157.90.0.0/16

75% of fediverse servers are behind BGP prefixes that host 10 or fewer servers, meaning that the fediverse is *very* resilient to large network outages.

Top countries where fediverse servers are hosted:

871 United States
439 Germany
156 France
148 Japan
75 Finland
57 Canada
49 Netherlands
38 United Kingdom
26 Switzerland
26 South Korea
21 Spain
19 Sweden
18 Austria
17 Australia
15 Russia
12 Czech Republic
10 Singapore
10 Italy

Thanks to suggestions from others, I did this with a much larger dataset of 27k fediverse servers (10x as many as my last post). This time the data is from https://fedilist.com/instance Here's what I get: CloudFlare does sit in front of a large number of servers (4620) but a smaller percentage: 17% Hetzner is replaced by OVH, barely, as the second most popular host, each host about 11% of fediverse servers Top 10 networks in this dataset: 3000 Cloudflare, Inc. 2471 Hetzner Online GmbH 1009 DigitalOcean, LLC 861 OVH SAS 655 Akamai Connected Cloud 627 netcup GmbH 353 Amazon.com, Inc. 340 IONOS SE 334 Oracle Corporation 327 Contabo GmbH The astute reader will notice that this does not match what I said above re: Hetzner and OVH; this is because the first set of stats counts each *domain* once, and this set counts each *IP address* once. Many of the domains at OVH are hosted from a handful of IP addresses, this is likely due to masto.host but I didn't look deeply. Here are the top 10 IP addresses hosting fediverse servers: 681 94.23.75.107 (OVH) 657 54.38.247.97 (OVH) 481 151.101.3.7 (Fastly) 255 104.21.16.1 (CloudFlare) 251 178.33.220.142 (OVH) 184 50.56.249.138 (Rackspace) 172 217.182.80.236 (OVH) 166 104.22.76.159 (CloudFlare) 144 151.101.131.7 (Fastly) 135 139.99.39.10 (OVH Singapore) Now, the majority fediverse servers are on networks that host *five or fewer* fedivserse servers. Six thousand fediverse servers are the only one on their network. To take out half of the fediverse (remember, we're talking servers here, not users), you'd have to take out more than *three hundred networks*. Top countries in this bigger dataset: 7114 United States 4230 Germany 1248 France 862 Japan 605 Finland 599 United Kingdom 565 Netherlands 529 Canada 221 Australia 217 Switzerland And by continent (as defined by ipinfo): 8874 Europe 7661 North America 1218 Asia 250 Oceania 73 South America 24 Africa Several folks suggested other interesting analyses: * A post that peeks behind the CloudFlare curtain: https://blog.benjojo.co.uk/post/who-hosts-the-fediverse-instances * A cool site that displays similar data in a much more pretty form, and has some per-user data: https://fedi.wrm.sr/ * A graph that shows that while there are big instances of course, users are actually spread across a large set of instances overall: https://aus.social/@Drbruced/114335400872850185 Thanks to the people that brought these to my attention! Finally, a more complete map: https://ipinfo.io/tools/map/190d4a54-1b40-4749-ad1b-17524bed11ea

미아역에서 칼부림 사건이 있었구나. 이런 짓하고 교도소 들어가도 그럭저럭 지낼만 하니까 이러고 사는 거겠지. 제정신 아닌 놈들이 세상에 이렇게 많아서야 안심하고 살 수가 있을까

When fascists make lists, bad things are coming.

They want to make lists of autistic people. Of women likely to seek abortion. Of undocumented immigrants.

Discretion and privacy are more important than ever now. Don’t track things electronically if it can be avoided. Don’t broadcast resistance efforts. Use encrypted messaging and leave your cellphone at home.

It might save a life.

가장 우수한 ‘건강 노화’ 식단은 무엇일까요? 공동연구진이 시중의 8가지 건강 식단을 비교한 결과, 하버드대가 개발한 대체건강식단이 1위를 차지했습니다. 이 식단은 과일과 채소, 통곡물, 견과류, 콩류, 불포화 지방 위주로 구성돼 있습니다. 붉은 고기와 가공육, 설탕이 많이 들어간 음료, 소금은 최소한 섭취합니다.
