Nice you could choose if you would like your gasoline with or without service :-) (4:00).
Why was the chain called "Der Wienerschnitzel" and not "Das Wienerschnitzel". It is (was) a proper noun, but why the wrong article? (5:02)
A small part appears twice (from 8:51--9:06).
more cyclists than I see in current streetview footage
Coca-Cola delivery vans where yellow?
I very much liked reading his "computer related risks" book (multiple times...) more than 25 years ago and after that the RISKS Digest was one of my weekly "go to" for a very long time.
So it seems we need something like this [1] for IT infrastructure? ;)
Or in this case; just click on "map"
Saying that (hand)writing is irrelevant is a bit of a strawman implying I said writing hexadecimal numbers big-endian on paper matters for coding.
The second sentence, weather your customers know if they have been in the same room with a big-endian system (CPU alone doesn't matter) is irrelevant when the point is to write correct code. Many of then aren't interested in this or other details and that is ok as they are not responsible for the implementation.
Changing the endianness either direction did have show bugs to me several times, that could be fixed, and it was worth it for that alone.
Not only the System/390. Its also IBM i, AIX, and for many protocols the network byte order. AFAIK the binary data in JPG (1) and Java Class [2] files a re big endian. And if you write down a hexadecimal number as 0x12345678 you are writing big-endian.
(1) for JPG for embedded TIFF metadata which can have both.

Congratulations :-)
Very nice shots. It must be a great feeling to see one's own footage in a feature film!
How long do you do astrophotography?
It's always interesting to see how are things build in the Lumafields "Scan of the month". The the most interesting scan from Lumafield I saw was not a Scan of the month, but in "Adam Savage’s Tested: Surprising Flaws in 18650 Lithium-Ion Batteries" [1]

PS: Nice company logo btw. ;)
Thanks for the clarification
I'm really sad, even if I never met him personally and only knew him from his talks, his software and of course his blog.
I had hoped that after his illness he would be granted some time for personal life and recovery — which makes this news all the more shocking.
Sometimes I miss the times where you had a compact development environment, wit one installer. Your source produced a mostly self contained binary in a reasonable size, you had nice debugging support and quick turnaround times for a compiled language even on a small development machines. And all that for attractive price for a perpetual license (Borland times).
Today it seems I have to give the producer my email address for the 'free' "Delphi History PDF". Well, times have changed. :)
Thanks, didn't knew that and 11% further is quite a increase and not too far from the maximum possible.

So no #includedir, no LDAP integration, no log_input/output, no PAM integration ...?
I have seen the topic a bit late, but nevertheless:
I have learned 6502 assembler (and assembler) in general with "6502 assembly language programming by Lance A. Leventhal" (1979) [1] and "Apple Machine Language by Don Inman & Kurt Inman" (1981) [2]
For the 'internals' of the machine, I had "What's Where in the Apple: A Complete Guide to the Apple Computer by William F. Luebbert" (1985) amazon:[3]

From the article: "The consequences for a consumer buying a shady USB cable likely aren’t too bad".
I can't second that, but more to the software/driver side.
Without my knowledge, I once had a counterfeit cable that costed several days of my life. At that time, the FTDI drivers recognized (and as I read did some other things [1]) that a counterfeit cable was connected, but instead of simply disabling the function, they impeded it. In my case: After pressing the first few keys on terminal connection, the transmission from the device to the PC worked, but not the reverse direction. A long search for the error came to an end after I replaced the USB/RS232 with a new one. This was with windows, with Linux even the counterfeit worked.

I would say this is the prettiest interface I've seen for explaining seasons, analemma, solstice, ... to someone or experimenting myself.
Thanks for the find!
From the man page: Linux 5.14.
Before Linux 6.5, memfd_secret() was disabled by default and only available if the system administrator turned it on using "secretmem.enable=y" kernel parameter. [...]
"To prevent potential data leaks of memory regions backed by memfd_secret() from a hybernation image, hybernation is prevented when there are active memfd_secret() users."

Useful site if you are on to perf/eBPF/performance things with many examples and descriptions even for other uses as e.g. memory usage, disk usage (prefer heatmaps here but they are nice if you want to send someone a interactive view of their directory tree ...).
Every of the lightning talks itself had about 20 short different topics, And as I wrote these were examples, you didn't expect someone to re-enumerate them here all to refute your statement. You can easily find them yourself. Have look at this page, where others listed their favorites, there are many more. But I don't think from your reply you didn't look at the list of sessions yourself.
None of these interesting as "technical topic"? (only examples)

I am not a HIFI/TV aficionado, but the ACR [1] thing was new to me.
I hope it is not yet important for me as I never allowed a TV access to my LAN/WLAN. But with smart devices using accessible open WLANs to transmit who knows.

The sensitivity When I play with phypbox [1] there is a sensitivity in the µT range. From the web page [2] the device build has a 0.1 nT resolution and 50 ppm absolute accuracy.
I think, not from the surface, but have a look here [1], where the author referenced from the IIEE article has build a submergible sensor and detected (a know) boat.
Space shuttle had five.
Four of them operating in a redundant set and the fifth performing non critical task, as descripted in [1]. The fifth is also programmed by a different contractor in a different programming language: #1-4 running the Primary Avionics Software System (PASS) programmed by IBM in HAL/S and #5 programmed by a different team of Rockwell International in assembly.

I think only the Grand Tour program was possible every 175 years: From Wikipedia [1]: "that an alignment of Jupiter, Saturn, Uranus, and Neptune that would occur in the late 1970s would enable a single spacecraft to visit all of the outer planets by using gravity assists."
Gravity assists with more than one planet are more frequent. Cassini-Huygens [2] as example had five (Venus, Venus, Earth, Jupiter, Saturn)
I would suspect when the goal ist only to leave the solar system as fast as possible (and don't reach a specific planet) they are much more often.

If you are (obviously) interested in the matter you might find one of the Bell Labs articles discussed on HN:

"The Influence of Bell Labs" [2]
"Bringing back the golden days of Bell Labs" [3]
"Remembering Bell Labs as legendary idea factory prepares to leave N.J. home" [4] or
"Innovation and the Bell Labs Miracle" [5]
interesting too.

And the (early) availability of well made library, LibTIFF by Sam Leffler. I used it extensively from 1995 on, but only found out that according to Wikipedia is dates back to 1988!
I don't want to be petty, but there is no 'winter time', only standard time and summer time or 'daylight saving time'.
I first heard the term 'winter time' when it was discussed to decide weather to keep DST permanently or if people would like to keep 'winter time' always. And of course who would want to have winter-something always. ;)
