Hands-on experience is key in learning analog design - but waiting months for a tapeout slows everything down.

Peter Kinget built MOSbius, an “analog FPGA” that lets students experiment with real circuits in real time.

w. david marx, equating polyester and genAI: „Our generation's polyester salespeople are not deep thinkers and they don't care about the externalities of what they're doing. They’re here to sell us polyester. We don’t have to buy it, but more importantly, we don't have to feel bad about not buying it.“

This is the moment Rej's open source Z80 woke up and said hello!

After Zilog’s April 2024 announcement, ReJ quickly taped out a drop-in replacement to preserve retrocomputing and legacy systems.

Taped out on TT07, it's a landmark in democratizing chip design.

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

I boosted several posts about this already, but since people keep asking if I've seen it....

MITRE has announced that its funding for the Common Vulnerabilities and Exposures (CVE) program and related programs, including the Common Weakness Enumeration Program, will expire on April 16. The CVE database is critical for anyone doing vulnerability management or security research, and for a whole lot of other uses. There isn't really anyone else left who does this, and it's typically been work that is paid for and supported by the US government, which is a major consumer of this information, btw.

I reached out to MITRE, and they confirmed it is for real. Here is the contract, which is through the Department of Homeland Security, and has been renewed annually on the 16th or 17th of April.

usaspending.gov/award/CONT_AWD

MITRE's CVE database is likely going offline tomorrow. They have told me that for now, historical CVE records will be available at GitHub, github.com/CVEProject

Yosry Barsoum, vice president and director at MITRE's Center for Securing the Homeland, said:

“On Wednesday, April 16, 2025, funding for MITRE to develop, operate, and modernize the Common Vulnerabilities and Exposures (CVE®) Program and related programs, such as the Common Weakness Enumeration (CWE™) Program, will expire. The government continues to make considerable efforts to support MITRE’s role in the program and MITRE remains committed to CVE as a global resource.”

Dear CVE Board Member,
We want to make you aware of an important potential issue with MITRE’s enduring
support to CVE.
On Wednesday, April 16, 2025, the current contracting pathway for MITRE to develop,
operate, and modernize CVE and several other related programs, such as CWE, wil
expire. The government continues to make considerable efforts to continue MITRE’
role in support of the program
If a break in service were to occur, we anticipate multiple impacts to CVE, including
deterioration of national vulnerability databases and advisories, tool vendors, incident
response operations, and all manner of critical infrastructure.
MITRE continues to be committed to CVE as a global resource. We thank you as a
member of the CVE Board for your continued partnership.
Sincerely,
Yosry Barsoum
VP and Director

@mra simulating on a computer and prototyping on an fpga is pretty essential. I haven't heard of any successful designs being taped out without those steps. are you using verilog or another HDL?

2025-02-20

@mra there’s a community of people prototyping small cpu designs (among other things) and taping them out on a open source silicon process. The project is called tiny tapeout. Yes, it is on discord. Sadly, the open web doesn’t seem to be popular for hackers anymore.
