Over the past month, I’ve taken some off-time to tinker with
Based.Cooking, the cooking site I/we made a year or so

have been over 250 recipes submitted, but the hobbled-together static site

We don’t have meaningful social connections anymore like our parents or their parents geeration had. We are so scattered, that I am unsure how many of my friends are actually friends and how many are just professional contacts. Everytime I switch job, almost 70% of my friends suddenly fall out of contact. Heck, I don’t even know the people who live in next apartments both left, right, up and down on the same building. Socializing with my friends mean, setting up an appointment weeks ahead to see if we can align on a free-slot and this often involves all of us commuting to somewhere and disbanding by 22:00 hours because family, work next morning, chores to do, doctor appointment and other human things.

PEP 690: Lazy Imports
This PEP proposes a feature to transparently defer the execution of imported modules until the moment when an imported object is used. Since Python programs commonly import many more modules than a single invocation of the program is likely to use in practice, lazy imports can greatly reduce the overall number of modules loaded, improving startup time and memory usage. Lazy imports also mostly eliminate the risk of import cycles. ⌘ Read more

Alright, check this out. I just kinda completed today’s project of converting a jeans into a saw bag. It’s not fully done, the side seams on the flap need some more hand sewing, that’s for sure. No, I don’t have a sewing machine. Yet?

Image

At first I wanted to put in the saw on the short side, but that would have made for more sewing work and increased material consumption. As a Swabian my genes force me to be very thrifty. Slipping in on the long side had the benefit of using the bottom trouser leg without any modification at all. The leg tapers slightly and gets wider and wider the more up you go. At the bottom it’s not as extreme as at the top.

The bag is made of two layers of cloth for extra durability. The double layers help to hide the inner two metal snap fastener counter parts, so the saw blade doesn’t get scratched. Not a big concern, but why not doing it, literally no added efforts were needed. Also I reckon it cuts off the metal on metal clinking sounds.

The only downside I noticed right after I pressed in the receiving ends of the snap fasteners is that the flap overhangs the bag by quite a lot. I fear that’s not really user-friendly. Oh well. Maybe I will fold it shorter and sew it on. Let’s see. The main purpose is to keep the folding saw closed, it only locks in two open positions.

Two buttons would have done the trick, with three I went a bit overkill. In fact the one in the middle is nearly sufficient. Not quite, but very close. But overkill is a bit my motto. The sides making up the bag are sewed together with like five stitch rows. As said in the introduction, the flap on the hand needs some more love.

Oh, and if I had made it in a vertical orientation I would have had the bonus of adding a belt loop and carrying it right along me. In the horizontal layout that’s not possible at all. The jeans cloth is too flimsy, the saw will immediately fall out if I open the middle button. It’s not ridgid enough. Anyways, I call it a success in my books so far. Definitely had some fun.

Vulnerability Alert: Avoiding “Dirty Pipe” CVE-2022-0847 on Docker Engine and Docker Desktop
You might have heard about a new Linux vulnerability that was released last week, CVE-2022-0847, aka “Dirty Pipe”. This vulnerability overwrites supposedly read-only files in the Linux kernel host, which could enable attackers to modify files inside the host images from the container instance. If you use Docker Engine natively, we recommend you should update … ⌘ Read more

↳ In-reply-to » For instance I normally use the same RSA key/pair on all my workstations for my ssh client, because that's me, no-matter where I am. The only exception to this rule is I usually create a separate key for any "work" / " company" I am a part of.

@prologic@twtxt.net I have seen single use keys that are signed by a central PKI .. Keybase has one that uses a chatbot to generate the keys on the fly.

It just comes down to your threat model :)

↳ In-reply-to » @prologic Re: Chat system, What if the base specification included a system for per-user arbitrary JSON storage on the server? Kind of like XEP-0049, but expanded upon. Two kinds of objects: public and private. Public objects can be queried by anyone, private objects cannot and must be encrypted with the user's private key. Public keys could be stored there, as well as anything else defined by extensions. Roster, user block list, avatar, etc.

I would HIGHLY recommend reading up on the keybase architecture. They designed device key system for real time chat that is e2e secure. https://book.keybase.io/security

A property of ec keys is deriving new keys that can be determined to be “on curve.” bitcoin has some BIPs that derive single use keys for every transaction connected to a wallet. And be derived as either public or private chains. https://qvault.io/security/bip-32-watch-only-wallets/
