GIVE ANY AI AGENT ACCESS TO GOOGLE SEARCH WITH SERPAPI (SPONSOR) [4]

Agents are smarter when they can search the web. But scraping Google
gets expensive when you're burning extra tokens to parse messy SERPs
into readable text.

SerpApi [4] is the web search API [4] that gives you exactly what you
need, out of the box:

¨ SCRAPE GOOGLE AND OTHER SEARCH ENGINES

¨ INTEGRATE WITH A SIMPLE GET REQUEST that any agent can make; get
RESULTS IN .MD OR .JSON that any agent can read.

¨ Used by NVIDIA, ADOBE, SHOPIFY, and even the United Nations.

¨ Start with 250 free searches ¨ [4]

ANTHROPIC SAYS CLAUDE DRIVES 26% OF ITS RESEARCH AND DEVELOPMENT (3
MINUTE READ) [5]

Anthropic claims that its Claude chatbot drives more than a quarter
of its research and development work. There are over 30,000 agents
doing research and engineering work at Anthropic at any one time. Its
staffers collaborate with the chatbot for about 90% of their work. The
company is trying to create a framework to track agents and monitor
the amount of work they do.

HUAWEI'S PLAN TO BECOME CHINA'S NVIDIA (3 MINUTE READ) [6]

Huawei plans to release two new AI chips next year. The company has
now shipped more than 1,000 of its AI-computing systems to over 370
customers. China's AI chip market is projected to grow to $67 billion
by 2030. Huawei's chip-making technology still trails Nvidia's, but
the company is developing workarounds and new designs to squeeze in
more computing power while using less advanced equipment.

HELIX 2.5: ZERO-SHOT 30-HOME GENERALIZATION (14 MINUTE READ) [7]

Helix 2.5 is an advanced neural network pretrained on Index, Figure's global-scale dataset of human behavior. It can tidy living rooms, fold
towels, and make beds in homes it has never seen. The model is the
first evidence that whole-body intelligence can be learned from human experience and transferred to new scenarios. Index is now generating
roughly 35 minutes of new human experience every second - if Helix 2.5
is any guide, more data and compute should translate directly into
more of the physical world learned before a robot ever enters a new
home.

HOW SPACEX STREAMLINED THE RAPTOR ENGINE (17 MINUTE READ) [8]

The differences between the versions of the Raptor rocket engine are
stark. Many people initially didn't believe SpaceX when the company
released a picture of the three generations of the design. The
streamlining of the design also brought meaningful gains in
performance - the Raptor 3 provides about 35% more thrust than the
Raptor 1. This article looks at what specifically SpaceX changed that
allowed it to take the Raptor from a tangle of wires and pipes into
the svelte, streamlined engine it is today.

HACKING OPENAI (11 MINUTE READ) [10]

Researchers chained two critical vulnerabilities to compromise
multiple OpenAI employees' ChatGPT accounts in July. The accounts
could access internal OpenAI repositories and potentially many other connectors. They used one employee's Codex to open a PR in OpenAI's
internal monorepo. This post provides a full timeline of the
disclosure process and details about how the vulnerabilities were
discovered.

WEBKIT FEATURES FOR SAFARI 27.0 (142 MINUTE READ) [11]

The release notes on the WebKit features for Safari 27.0 are the
longest yet, detailing 83 features, including Safari MCP. Safari MCP
makes working with coding agents dramatically easier. It gives users'
agent of choice control over the browser window so it can see how code
renders. The MCP provides access to the DOM, network requests,
screenshots, and console output, allowing agents to do more with less
effort from users.

THE STARTUP THAT BUILT OPENAI'S BIGGEST DATA CENTER IS NOW MAKING
TINY ONES (6 MINUTE READ) [12]

Crusoe built one of the world's biggest AI supercomputers in Abilene,
Texas. The company is now investing heavily in smaller data centers.
It is manufacturing them in factories, loading them onto flatbed
trucks, and deploying them wherever it can find available power. The
company believes this is a faster and cheaper method than solely
relying on large construction projects. Giant clusters with hundreds
of thousands of chips are useful for training, but inference can be
done with considerably smaller amounts of chips.

INSIDE THE WHITE HOUSE TUSSLE TO SWAY TRUMP ON AI (11 MINUTE READ)
[13]

Anthropic's Mythos model sparked a shift within the White House as
officials started realizing that AI can be used to launch cyberattacks
and pose national-security threats. White House officials and AI
executives are working on regulatory efforts, but when they disagree,
the executives have gone directly to Trump. Trump has remained
resolute that the nation needs to accelerate AI development and
continue to build the data centers that are powering the AI boom.

I did notice you were using ASCII in Sylpheed, and now you're using CP437. I think you might have to use UTF-8, and that will also change your settings for quoted-printable and mime encoded messages (use what it sets for you).

As for quoting, depending on what you're using (ie. external editor, or the newsreader's built in editor).. I use nano as an external editor, and if you go to the first column of a paragraph, and hit CTRL-J, it will re-quote the paragraph in proper form. In Thunderbird, CTRL-R does the same thing. I'm not sure what to do with Tin's internal editor, though.

With nicks instead of traditional name-surname names, the
Fido-style quotaiton does not seem to work very well, so
I'll use playwright style to summarise the preceding
discussion and post a followup under an updated title:

ant:

Accession:
I did notice you were using ASCII in Sylpheed, and now
you're using CP437. I think you might have to use UTF-8,
and that will also change your settings for quoted-
printable and mime encoded messages (use what it sets for
you).

Having investigated this issue, I conclude that it is caused
not by encoding settings in either Sylpheed or Tin, but
rather by the structure of TLDR's multipart attachments,
which has been broken since On 2026.02.02.

All of TLDR's posts made prior to 2026.02.02 are displayed
correctly both in Tin and Sylpheed, either newsreader
showing them as consisting of two parts/attachments: one
text/plain and one text/html. They are correcty formed
multiplart messages. For example, consider his last correct
post:

Subject: SpaceX merger ?, OpenAI races Anthropic IPO ?, AI replacing SaaS ??
Message-ID: <0100019c0ea4deb1-d7058a49-2933-4217-bd2b-3ca4760a2955-000000@email.amazonses.com>
Date: Fri, 30 Jan 2026 11:23:31 +0000

It has:

Content-Type: multipart/alternative; boundary=HEQT47yB

and if you look for `--HEQT47yB' in the article body, you
will find the individual parts terminatd by a closing
boundary:

--HEQT47yB
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: quoted-printable

SpaceX may potentially merge with Tesla and xAI. Some investors are
[...]
--HEQT47yB
Content-Type: text/html; charset=utf-8
Content-Transfer-Encoding: quoted-printable

<!DOCTYPE html><html lang=3D"en"><head><meta http-equiv=3D"Content-Type" co=
ntent=3D"text/html charset=3DUTF-8"><meta charset=3D"UTF-8"><meta name=3D"v=

=3D"light dark"><meta name=3D"supported-color-schemes" content=3D"light dar=
k"><style type=3D"text/css">
[...]
--HEQT47yB--

This is a correctly formed multipart message, compliant with
RFC1341.

Now consider the first "broken" message:

Subject: Elon needs capital ?, Nvidia OpenAI deal stalls ?, tech loyalty is dead ?
Message-ID: <0100019c1e1a756e-3581d6a7-96dc-4b59-9e84-d08de7ef1ec3-000000@email.amazonses.com>
Date: Mon, 2 Feb 2026 11:26:16 +0000

Similar to the correct ones, it also has

Content-Type: multipart/alternative; boundary=h5nkvOqh

yet, if you search for `--h5nkvOqh', you shall find naught,
indicating that this "multiplart" message has no parts,
violating RFC1341, which requires "one or more" parts:

In the case of multiple part messages, in which one or
more different sets of data are combined in a single
body, a "multipart" Content-Type field must appear in the
entity's header. The body must then contain one or more
"body parts," each preceded by an encapsulation boundary,
and the last one followed by a closing boundary.

My newsreaders are therefore correct in displaying it as an
empty message.

Interestingly, TLDR's messages became malformed after this
post:

From: "Mortar" (VERT/EOTLBBS) <VERT/EOTLBBS!Mortar@nix.synchro.net>
To: finglonger
Subject: TLDR Reception
Message-ID: <697D1C92.646.dove-techtalk@endofthelinebbs.com>

where the poster complains that he cannor read them.

Since a since user's inability to read correct multipart
messages is a bad excuse to start posting in a malformed, non-standard-complying format, I hereby ask TLDR to please
either revert to the previos correct format, or -- much
better -- to post normal non-MIME plain-text messages.

I think you are talking about reflowing text within a given
quoting style, so that it fits a sensible line length (e.g.
72 characters), rather than using different quoting styles.

Do nano and TB support both e-mail style quotations (as
above), and Fidonet-style ones, as below:

There is not such thing as Tin's built-in editor. It relies
on an external one, and I am using vi.

Although your own posts are declared as format=flowed, they
are not flowed at all, using MS-style with each paragraph
represented as a single long line, whereas true
format=flowed paragraphs are wrapped to 72 characters per
line or so, with each line but the last ending in a trailing
space.

reflow quotations, but I cannot configure Tin or Sylpheed to

Okie dokie.. think what you want, but:

Thunderbird:
https://pharcyde.org/tldr-tb.png

slrn (which displays these exactly the same as Tin): https://pharcyde.org/tldr-slrn-headers.png https://pharcyde.org/tldr-slrn-message.png

I don't currently have tin installed, because I like slrn better. However, I have installed and used tin.. and it displays the messages exactly the same as slrn does, when setup correctly.

The date of the message is 9 days ago, which makes your investigation wrong.

For example, consider his last correct post:

Subject: SpaceX merger ?, OpenAI races Anthropic IPO ?, AI replacing SaaS ??

There's nothing correct about the question marks in the subject line above. That looks like if UTF-8 glyphs were to be viewed in something setup for CP437. om which it can't be translated.

--HEQT47yB
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: quoted-printable

Note "charset=utf-8" while you're using ascii and/or cp437.

Now consider the first "broken" message:

Subject: Elon needs capital ?, Nvidia OpenAI deal stalls ?, tech loyalty
is dead ?

Again, question marks where there are supposed to be UTF-8 glyphs. I can't really take your word for it if you can't keep the original message in tact as it was originally written.

My newsreaders are therefore correct in displaying it as an empty message.

Ok, lol.

Well, then ignore them, because they display perfectly fine for me and others. They even display fine, when Synchronet itself is configured correctly (ie. logged into the BBS). Is it possible that the specific site where you are viewing them from is messing up the original messages?

Since a since user's inability to read correct multipart
messages is a bad excuse to start posting in a malformed, non-standard-complying format, I hereby ask TLDR to please
either revert to the previos correct format, or -- much
better -- to post normal non-MIME plain-text messages.

Or, just ignore the message area if it doesn't work for you. Since you're using a newsreader, you can simply just unsubscribe.

It works for me, and I vote to keep it as is. ¨

If you can't see the UTF-8 glyph I just included in the line above, it's a "you" thing (or something messed it up between me and you).

Accession

Granted, I /rarely/ quote past the first quote level when replying to a message.

There is not such thing as Tin's built-in editor. It relies on an external one, and I am using vi.

Ok then, "gq" or "gqip" maybe? I don't use vi, but vi(m) also has the ability to do this.

Although your own posts are declared as format=flowed, they
are not flowed at all, using MS-style with each paragraph represented as a single long line, whereas true
format=flowed paragraphs are wrapped to 72 characters per
line or so, with each line but the last ending in a trailing space.

If you say so.

Definition of Format=Flowed

Format=flowed is a specification for formatting plain-text emails that allows for dynamic line wrapping. This method enables email clients to adjust the display of text based on the recipient's screen width while preserving the original structure of the message.

Seems like your side should wrap it to under 80 characters (see "enables email clients") if you want it to be. I can resize my screen and the text takes up the whole width at any given time.

Tin can definitely support different quote prefixes, including initials before the quote character. Tin even mentions "fidonet-style quoting" in their documentation. Have you read it yet?

Having investigated this issue, I conclude that it is
caused not by encoding settings in either Sylpheed or
Tin, but rather by the structure of TLDR's multipart
attachments, which has been broken since On 2026.02.02.

Okie dokie.. think what you want

It is not a question of what I want, but rather of what is
true, so pray don't dismiss my opinion that way. After all,
I have provided evidence to support it. Have you anything
to say against my evidence?

Thunderbird:
https://pharcyde.org/tldr-tb.png

Thunderbird displays it as an HTML page. How did you
receive it in Thunderbird -- as an e-mail, or an NNTP
article? On my NNTP side, the entire raw message has not a
vestige of HTML:

<https://freeshell.de/~antonius/news/tldr-20260920.txt>

so I am at a loss what Thunderbird is showing. Can you post
the same entire raw message as seen on your NNTP side?

https://pharcyde.org/tldr-slrn-headers.png

This is /most/ interesting, becase your slrn reports:

Content-Type: text/plain; charset=utf-8

whereas my Tin and Sylpheed report:

Content-Type: multipart/alternative; boundary=HcXDvzbz

Since headers are an inherent part of the message, our
clients have nothing to do with it. It seems that your NNTP
server provides those articles differently from mine. My
NNTP server is <nntp://nix.synchro.net>. What is yours? If
they are substantially different, that will expalin the
situaion: all newsreaders on your side render it correct,
and none does on my side.

https://pharcyde.org/tldr-slrn-message.png

Normal rendering of a normal plain-text message.

Subject: SpaceX merger ?, OpenAI races Anthropic IPO ?,
AI replacing SaaS ??

There's nothing correct about the question marks in the
subject line above. That looks like if UTF-8 glyphs were
to be viewed in something setup for CP437. om which it
can't be translated.

Right. There is an encoding problem somewhere in the path.
Let us ignore it for now and focus on the message stucture,
because our NNTP servers seem to be perceiving the same
message differently. Perhaps my server is somehow
truncating the messages, amputating HTML parts, and magling
the articles in the process. This is why I propose that we
compare /the entire raw message/ between you and me. This
will provide the ultimate source of truth, independent of
the local encoding, mime, and other settings in our clients.

Note "charset=utf-8" while you're using ascii and/or
cp437.

Yes, I have noted that. My message are encoded CP437 in Tin
and US-ASCII in Sylpheed. But the endoing of outoing
messages does not interefere with the parsing of incoming
ones. They are totallyl orthogonal.

My newsreaders are therefore correct in displaying it as
an empty message.

Ok, lol.

Why do you cut my explanation and laugh?

They even display fine, when Synchronet itself is
configured correctly (ie. logged into the BBS). Is it
possible that the specific site where you are viewing them
from is messing up the original messages?

This is my current hypothesis, exactly. I read those
messages via <nntp://nix.synchro.net> .

Or, just ignore the message area if it doesn't work for
you. Since you're using a newsreader, you can simply just
unsubscribe.

Nah, it does not fix anything.

It works for me, and I vote to keep it as is. _

If the problem I am having is caused by
<nntp://nix.synchro.net>, rather than TLDR, then I agree.

If you can't see the UTF-8 glyph I just included in the
line above, it's a "you" thing (or something messed it up
between me and you).

Or something in the route of the message from its origin to
you and to me. I now conjecture it was distorted on the way
to my side.

Yes, and yes, and I have said so several times. The problem
is that the quoting settings in Tin are /global/ and apply
to all newsservers, whereas I need e-mail-style quotes on
conventional Usenet servers and FidoNet-style quotes on
FidoNet and BBS bridges.

Is it the same way with slrn?

The bug is/was in Synchronet (not fixed upstream). Synchronix (the BBS you're using) could've work around it by enabling MIME-encoded messages in their QWK hub configuration (for VERT) in SCFG, but now they shouldn't need to do that since the fix was on the hub's side and already made/in-place. You should not get those MIME headers (on nix.synchro.net / DOVE-Net subs) going forward.

I mean, there /are/ settings for mime and quoted printable messages in tin, so maybe I was able to change mine to make it work? I think by default tin wants to export the message and view it somewhere else. I changed that setting to use the internal viewer, which worked. *shrug*

There is not such thing as Tin's built-in editor. It
relies on an external one, and I am using vi.

Ok then, "gq" or "gqip" maybe? I don't use vi, but vi(m)
also has the ability to do this.

gq is a Vim invention. But in vi one can process a
paragraph with an artibrary shell command, and, as I said,
par is made exactly for that purpose. Only it is a tad
tricky to learn. The manual ends with an apology from the
author:

Back in 1993 I had very little experience at writing
documentation for users, so the documentation for Par
became rather nightmarish.

Although your own posts are declared as format=flowed,
they are not flowed at all, using MS-style with each
paragraph represented as a single long line, whereas
true format=flowed paragraphs are wrapped to 72
characters per line or so, with each line but the last
ending in a trailing space.

If you say so.

It is not a matter of what I say, but of what is true.

Definition of Format=Flowed:

Format=flowed is a specification for formatting plain-
text emails that allows for dynamic line wrapping. This
method enables email clients to adjust the display of
text based on the recipient's screen width while
preserving the original structure of the message.

It is not the definition of format=flowed, but a loose
description of its purpose. It does not make the crucial
distinction between format=flowed and the primitive
longlinoitus -- the vicious practice of writing every
paragraph in a single line, no matter how long.
format=flowed was invented exactly to allow wrapping text to
arbitrary margins, while preserving the short lines and hard
line breaks required of tranditional text files, and
expected in traditional e-mail and Usenet clients, as
explained in RFC3676:

When generating Format=Flowed text, lines SHOULD be 78
characters or shorter, including any trailing white space
and also including any space added as part of stuffing
(see Section 4.4). As suggested values, any paragraph
longer than 78 characters in total length could be
wrapped using lines of 72 or fewer characters. While the
specific line length used is a matter of aesthetics and
preference, longer lines are more likely to require
rewrapping and to encounter difficulties with older
mailers. (It has been suggested that 66 character lines
are the most readable.)

The restriction to 78 or fewer characters between CRLFs
on the wire is to conform to [MSG-FMT].

(In addition to conformance to [MSG-FMT], there is a
historical need that all lines, even when displayed by a
non-flowed-aware program, will fit in a standard 79- or
80-column screen without having to be wrapped. The limit
is 78, not 79 or 80, because while 79 or 80 fit on a
line, the last column is often reserved for a line-wrap
indicator.)

Your lines are wa-a-ay longer than 78 characters, not to
mention 66. And none of your lines end with a traling space
character, so no -- your messages are not in format=flowed,
despite the declaration in the headers.

Seems like your side should wrap it to under 80 characters
(see "enables email clients") if you want it to be.

Not at all. By construction, format=flowed is backwards
compatible with the normal hard-wrapped text, so as not to
break traditional clients, yet let ff-aware ones to wrap
text to the available width.

I can resize my screen and the text takes up the whole
width at any given time.

This is not due to format=flowed, but due to soft-wrap in
your client. Windows Notead can do exactly the same, for
example, as well as any program expecting one long line per
paragraph, which includes the overwhelming majoriy of modern
text editors.

According The Chicago Manual of Typographical Style, a
comfortable line length is about 65 characters, so I am
often forced to resize my browser window in order to read
comfortably. Better websites, of course, have CSS
configured to limit the line length. 72-characters line I
can manage too, and I never ever let my code have lines
beyong 80 characters.
