bsub get job stdout and stderr Updated 2025-07-16
By default, LSF only sends you an email with the stdout and stderr included in it, and does not show or store anything locally.
One option to store things locally is to use:as documented at:
bsub -oo stdout.log -eo stderr.log 'echo myout; echo myerr 1>&2'Or to use files with the job id in them:
bsub -oo %J.out -eo %J.err 'echo myout; echo myerr 1>&2'By default as mentioned at:
bsub -oo:To get just the stdout to the file, use
bsub -N -oo which:- stores only stdout on the file
- re-enables the completion email
Another option is to run with the bsub This immediately prints stdout and stderr to the terminal.
-I option:bsub -I 'echo a;sleep 1;echo b;sleep 1;echo c' bsub on foreground Updated 2025-07-16
Run Ctrl + C kills the job on remote as well as locally.
bsub on foreground, show stdout on host stdout live with an interactive with the bsub -I option:bsub -I 'echo a;sleep 1;echo b;sleep 1;echo c'; echo done btcdeb Updated 2025-07-16

Bicycles require too much maintenance Updated 2025-07-16
It is true, something Ciro Santilli often things about. One likely reason is that the world is broken and most cyclist are speed maniacs willing to put the time in. Unlike Dutch people where everyone cycles.

This just works, but it is also so incredibly slow that it is useless (or at least the quality it reaches in the time we have patience to wait from), at least on any setup we've managed to try, including e.g. on an Nvidia A10G on a g5.xlarge. Running:would likely take hours to complete.

Cool data embedded in the Bitcoin blockchain Ordinal ruleset inscription collection Updated 2025-07-16
This section is about groups of ordinal ruleset inscription that share a theme and were presumably created by a single entity.
Mainsbury’s Updated 2025-07-16
The relatively large Sainsbury's located at 42-45 Sidney St, Cambridge CB2 3HX. Existed in late 2010's and early 2020's Ciro Santilli witnessed.
Being the only relatively large grocery shop in central Cambridge near several colleges, where manu students live, makes this one of the most popular grocery shopping location for many of the students.
Cool data embedded in the Bitcoin blockchain Ordinal ruleset inscription Updated 2025-07-16
Ordinals are inscriptions created with the protocol described at: docs.ordinals.com/inscriptions.html The protocol was designed by developer Casey Rodarmor, and shares a few similarities with the AtomSea & EMBII protocol.
The protocol also includes a way to have ownership over inscriptions, effectively creating an NFT system on top of the bitcoin blockchain. AtomSea & EMBII also already had such a system however. In either case, Ciro Santilli couldn't give less of a fuck about who owns some random publicly viewable digital asset.
For whatever reason, orinals became extremelly popular compared to the AtomSea & EMBII format, leading to millions os inscriptions, and 10k+ images as of block 830k. They also started to take up a substatial portion of the available block space.
This in turn led to a lot of child porn rediscussion, and people linking back to this page to view earlier inscriptions: incoming links.
Unfortunately, unlike AtomSea & EMBII and even cryptograffiti.info uploads, most ordinals are designed to be just souless bulk collectibles, as with as much artistic merit as any random collectible card set or postage stamps you may find at a newpaper stall. To make things worse many of them are likely algorithmically generated. Eternal September had truly arrived to the Bitcoin blockchain. As a result, machine learning would be almost essential in order to find interesting uploads amidst such bulk.
Ordinal #0
. This is the first ordinal ruleset inscription: ordinals.com/inscription/6fb976ab49dcec017f1e201e84395983204ae1a7c2abf7ced0a85d692e442799i0. It was made on block 767430 (2022-12-14).The
i0 at the end of the URL above means "inscription 0". This is because a single transaction can have multiple inscriptions.
The ordinals also started taking up large portions of the Bitcoin blockchain:
Apparently the "Taproot" Bitcoin update made it easier to upload image-sized data once again, which had become prohibitively expensive 2023 and much earlier:

This is the most common home "ethernet cable" as of 2024. It is essentially ubiquitous. According to the existing Ethernet physical layer, the maximum speed supported is 2.5 Gbit/s.
Quantum interconnect Updated 2025-07-16
"Quantum interconnect" refers to methods for linking up smaller quantum processors into a larger system.
As of 2024, seemingly few organizations developing quantum hardware had actually integrated multiple chips in interconnects as part of their main current roadmap. But many acknowledged that this would be an essential step towards scalable compuation.
The name "quantum interconnect" is likely partly a throwback to classical computer's "chip interconnect".
Sample usages of the term:
- news.mit.edu/2023/quantum-interconnects-photon-emission-0105
Researchers have demonstrated directional photon emission, the first step toward extensible quantum interconnects

pastebin.com/CTXnhjeS dated mega early on Sep 30th, 2012 by CYBERTAZIEX.
This source was found by Oleg Shakirov.
This pastebin contained a few new hits, in addition to some pre-existing ones. Most of the hits them seem to be linked to the IP 72.34.53.174, which presumably is a major part of the fingerprint found by CYBERTAZIEX, though unsurprisingly methodology is unclear. As documented, the domains appear to be linked to a "Condor hosting" provider, but it is hard to find any information about it online.
From the title, it would seem that someone hacked into Condor and defaced all of its sites, including unknowingly some CIA ones which is LOL.
Ciro Santilli checked every single non-subdomain domain in the list.
Other files under the same account: pastebin.com/u/cybertaziex did not seem of interest.
The author's real name appears to be Deni Suwandi: twitter.com/denz_999 from Indonesia, but all accounts appear to be inactive, otherwise we'd ping him to ask for more info about the list.
www.zone-h.com lists some of the domains. They also seem to have intended to have snapshots of the defaces but we can't see them which is sad:
