I have updated my eventDB to have subscriptions! It now has websockets like msgbus. I have also added a in memory store that can be used along side the disk backed wal.

I did a take home software engineering test for a company recently, unfortunately I was really sick (have finally recovered) at the time 😢 I was also at the same time interviewing for an SRE position (as well as Software Engineering).

Got the results of my take-home today and whilst there was some good feedback, man the criticisms of my work were harsh. I’m strictly not allowed to share the work I did for this take-home test, and I really can only agree with the “no unit tests” piece of the feedback, I could have done better there, but I was time pressured, sick and ran out of steam. I was using a lot of libraires to do the work so in the end found it difficult to actually think about a proper set of “Unit Tests”. I did write one (in shell) but I guess it wasn’t seen?

The other points were on my report and future work. Not detailed enough I guess? Hmmm 🤔

Am I really this bad? Does my code suck? 🤔 Have I completely lost touch with software engineering? 🤦‍♂️

Hi, I am playing with making an event sourcing database. Its super alpha but I thought I would share since others are talking about databases and such.

It’s super basic. Using tidwall/wal as the disk backing. The first use case I am playing with is an implementation of msgbus. I can post events to it and read them back in reverse order.

I plan to expand it to handle other event sourcing type things like aggregates and projections.

I’m trying to switch from Konversation to irssi. Let’s see how that goes. Any irssiers out there who can recommend specific settings or scripts? I already got myself trackbar.pl and nickcolor.pl as super-essentials. Also trying window_switcher.pl. Somehow my custom binds for Ctrl+1/2/3/etc. to switch to window 1/2/3/etc. doesn’t do anything: { key = "^1"; id = "change_window"; data = "1"; } (I cannot use the default with Alt as this is handled by my window manager). Currently, I’m just cycling with Ctrl+N/P. Other things to solve in the near future:

• better, more colorful and compact theme (just removed clock from statusbar so far)
  
• getting bell/urgency hints working on arriving messages
  
• nicer tabs in status bar, maybe even just channel names and no indexes
  
• decluster status bar with user and channel modes (I never cared about those in the last decade)

Hmm, @prologic@twtxt.net / @lyse@lyse.isobeef.org: Should we remove the section “Traditional Human-Readable Topics” from the spec? Or mark is as deprecated? I haven’t seen this being used in the wild for years. 🤔

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.

I’ve noticed a gradient of skepticism about climate change, ranging from outright contradiction that it exists to debates about the specific measures needed to reverse acknowledged warming trends. Using the general term “climate change denial” to describe that entire gradient, and thus treating all forms of skepticism as equally ignorant, seems counterproductive to me.

@lyse@lyse.isobeef.org Excellent use of old denim, and also excellent use of long-form twt!

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?

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.

@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 :)

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/

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.
