What is Hackers' Pub?

Hackers' Pub is a place for software engineers to share their knowledge and experience with each other. It's also an ActivityPub-enabled social network, so you can follow your favorite hackers in the fediverse and get their latest posts in your feed.

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)

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!

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.

@wancw寫 code 求生的鼯鼠 🦊 kotobank.jp/word/%E7%AA%81%E3%

日語「ツッコミ」的意義跟「黜」這個漢字所表記意義,可能是有點差距的。就算談漫才,在日語中不一定是表示“disrespect” 「貶」這方面的意圖,而是「在笑點出現時說句話」而以。(對觀眾說:這邊可以笑一下)

所以華語的對應詞大概就是選一個最接近日常生活中會用到的就好了。比較通用一點的語境內是或許是「指點」,比較輕鬆一點的話就是「戳」。

@server_destroyer:biological_server: 수다쟁이 렌게쨩 (お喋りレンゲちゃん) :sabakan: @draco드라코 쉽게 설명해서 대칭키는 스파이랑 본국이 같이 들고 있는 공유 비밀서적, 비대칭키는 아무나 잠글 수는 있는데 나만 열 수 있는 자물쇠입니다
비대칭키는 회사 정보가 유출당해도 내 키를 복제할 수 없어요 (대신 해커가 자기 키에 해당하는 공개키로 수정해 등록하는 건 가능 = 인감도장 새로 파서 등록)

@server_destroyer:biological_server: 수다쟁이 렌게쨩 (お喋りレンゲちゃん) :sabakan: @draco드라코 그래서 다들 이미 회사가 털렸는데 내가 가지고 있는 uSIM에 PUK로 암호 걸어잠그는 게 뭔 소용이냐고 욕하는겁니다

그리고 유심보호서비스는 같은 키를 가지고 와도 "너는 파란 옷을 입고 온다고 했을텐데?" 하고 다른 옷을 입고 오면 거부하는(=핸드폰 고유번호인 IMEI가 다르면 잠가버림) 서비스고 IMEI까지 다 털린 마당이라 실질적으로 소용이 없다 보시면 됩니다

客人說:「就算是有毒父母,還是應該去見他們的最後一面喔。」

我(唉~又來了,又是正論是不是…😌真是的):「你為什麼會這樣想?」

客人:「因為看到那種快死的討厭鬼,會覺得他們超沒用的,笑死我了。」

我:「你…還好嗎?」
