My home office gets up to about 1500ppm of CO2 by the end of the workday, which explains a lot about why I often feel exhausted after the end of a long, uninterrupted session in there (especially when I’m on back to back zoom calls). I now have several plants in there that are supposed to be especially good at sucking up CO2, and my sensor reports that the current level is slightly below atmospheric ambient CO2 level…

It's about a company (https://neoplants.com/ ) which genetically enhances plants and soil with a product you can buy to make them much more efficient at filtering the air. It apparently does work rather than being a placebo.

I have started exploring Seneca/stoicism again. Prompted partly by a recent submission here, partly by personal reasons. Instead of consuming other peoples interpretation of stoicism I decided to go as close to the source as feasible for me. I have read Letters from a stoic a number of times before and my copy is filled with highlights, but this time I think I will try to limit myself to one or two letters a day and…

Based on some reading in a study group using both the Hays and Waterfield translations, I'd definitely recommend Waterfield over Hays.

Interesting. I have read quite a few translations of Meditations by Marcus Aurelius and also found a clear favorite. But I am actually not even sure which translation of Letters from a Stoic my current book is. I have just always liked the language in it.

An intern had trouble with an outdated exercise in Elixir that use an old version of an Erlang dependency, so we got to figure out how to depend on a local copy, dig into the Erlang code and do a little hack to make it work.

Basically it relied on a checksum algorithm that was previously in yet another external library but was now in the standard library so that call needed to be updated and variables carrying around the old external library had to be underscored out.

It was a good lesson in traversing error messages and going from an angry VM step by step to a clean success. Not to hairy for a junior to understand when explained, and also not too time consuming to burn out interest, while still a bit of a challenge.

Good read thanks. I totally can relate to the choices problem. It's rather easy with physical books (or was, as we have little room left for even more books ;-0) but ebooks are "dangerous" too. Regarding cameras, it's harder (and more expensive) to wrangle with gear acquisition syndrome (GAS) but after switching from Canon EOS to Fuji, because the Canon stuff was too heavy when hiking, I managed to restrain myself mo…

Thanks a lot! Yes, I agree that it is easier with physical books although even there I can already see that I may be painting myself into a corner. But ebooks are obviously "worse" in that regard. I loved when I found StandardEbooks.org and Gutenberg - all these classic books for free. But over time I have realized that I have so many of them on my kindle and always seems to find new ones rather than finishing existing.

With regards to cameras, I also came to Fuji although from Nikon. But I agree, the important part is getting better at photography and the better you know your camera the more it can become an extension of yourself.

There is just something very alluring about the daydream of having the new camera and taking those "perfect" images. When in fact nothing is keeping me from going out and shooting those "perfect" images with the camera I already have.

"I always wonder why birds stay in the same place when they can fly anywhere on the earth. Then I ask myself the same question." - Harun Yahya

This was always a flawed quote because even before such a realization, people still did novel things (and literally flew to new places), much the same as birds. And the answer is still the same for birds and humans, the constraint of resources. If you have enough then by all means, fly.

The point is for you to take a look at yourself and how you are currently spending your time, from the assumption that you could do something different.

I've learned that being truthful in your resume as a SWE doesn't work anymore. I've had nearly 0 response rate to my applications, even if I was nearly a perfect match. Dude that we fired a while ago for being abysmally bad and non-productive gets interviews, raises and just got into ycombinator backed company by making up 75% of his resume(which I saw). We need a reset, this is getting ridiculous.

Same general experience. I have seen friends and former coworkers who I know are mediocre devs but good at talking themselves up get placed multiple times this year.

I've secured a single interview, company seemed like a great fit. System level Go apps, my bread and butter. No longer have to split my time with frontend? The dream.

On round 2 their CTO basically shut me down 2 minutes in saying they're unwilling to do any sort of training and only looking for existing experts in their very specific niche. In round 1 the interviewer told me I seemed like a very good candidate, very positive about my experience. Said they'd been looking for a long while and I was one of the most experienced Go backend developers they'd interviewed. Round 1 was frankly one of the most positive interviews I'd ever had. Got extreme whiplash as round 2 was cut short at about the ten minute mark.

I don't know for sure but I think a lot of companies are looking for an absolute Cinderella given the glut in applications. I don't think that guys going to find her.

It's been a couple months now, their job posting is still up. I'd have been well up to speed and making meaningful contributions by now.

People already do that. It also doesn't relate to the person you replied to, as I said in another comment, it's about an external source imprisoning you, not you imprisoning yourself.

Whats a good place to see parallel arrays defined. I have no data lake expetience. Know how relational db works.

I mean, Table1 = {"col1": [1,2,3]} Table2 = {"epiphany": [1,1,1]} for i, r in enumerate(Table1["col1"]): print(r, Table2["epiphany"][i]) He's really happy he found this (Edit: actually it seems like Chang She talked about this while discussing the Lance data format[1]@12:00 in 2024 at a conference calling it "the fourth way") and will represent this in a conference.

That code is for in memory data right? I see no storage access.

What is really happening? Are these streaming off 2 servers and zipped into 1. Is this just columnar storage or something else?

I got a handheld emulator console as a Christmas gift. Configuring shaders that emulate crt TVs, I realized I had no mental model of how those TVs worked at all. I’m used to “pixels are three little lights combining rgb colors”, which doesn’t work here, so I went on a rabbit hole and let me tell you, analog TVs are extremely impressive tech. Getting an electron beam to hit a glass, making the chemicals on it spark, c…

What other sci fi technology is being lost on us now? I always that the complexity of the local-battery-powered copper-cable telephone exchange system was bonkers. It was the backbone for all our landline calls.
