jaxr··on What is a database transaction?
I love the work planetscale does on keeping this type of content accurate yet accessible. Keep it up!
jaxr··on Why I don't ride the AI Hype Train
Lost me un the first section. It's like when anti-vaxers say vaccines are bad because they were developed unethically. It's just a bad argument.

Also, I learned about Bitcoin when it was worth 8 USD and got obsessed with the tech but always thought it was over hyped. I never owned one Satoshi. I still think crypto ended up being hype and not adding real value to the world. But I could be very very wealthy if I had jumped to that hype train XD.

I think with all the hype, AI does provide some real value to the world. That's the train I'm jumping in.

jaxr··on The Einstein AI Model
The most useful way to leverage LLMs for me has been as "content fillers". I'm a software engineer, and work with a rather large code base. Some parts are rarely touched, and loading the context into my brain whenever I need to go back to them requires quite a bit of effort. I found that asking cursor/Claude to suggest how to make the required chande rarely comes up with the right solution but usually points me in the right direction and is enough to help me load the context up. Similarly with my side projects, which typically involves knowledge that I don't use in my day to day.
jaxr··on Are noise-cancelling headphones to blame for young people's hearing problems?
I get that feeling too. I have the Samsung Galaxy buds3 pro. They seem to be worse than my Bose 700. After wearing them for a while with NC, I feel like I have to take them off or turn the sound louder. I defaulted to using them with NC off unless I'm in a very loud environment.
jaxr··on Most-Watched Software Engineering Talks of 2024
It clearly says the most watched talks, so yes. The author mentions in the article "from the conferences I follow"
jaxr··on Ask HN: Would you recommend a framework laptop?
I mostly loved mine... While it lasted. I owned a 12th gen, and it ran really well. The stories about running hot, draining battery while sleeping and the lack of firmware updates are all true. I could live with that. I live in Argentina, and had to travel to SF for work. I ordered the tougher hinges in advance (the ones that came were very flimsy, but they fixed that in newer models). I changed the hinges, and it was a breeze, so they delivered there. The thing is.. the laptop never booted up again! I called support, and they instructed me several things to try bring it back to life. Nothing worked. Last message was: you're out of warranty, sorry. Which I'm ok with. But then it got me thinking about repairability. I'm by no means a hardware expert. For sure I messed up when changing the hinges. But still, the whole situation just fell awful, and the promise if repairability just stopped selling for me. I still want framework to exist. I love their mission. But I needed to work, so I ran to an apple store and bought a MBP. After 20 years of using Linux, it breaks my heart a little bit, but the hardware is unbeatable. I'm kind of hating macos tbh, but I can live with it. And who knows, Asahi might get good enough at some point...
jaxr··on YC is wrong about LLMs for chip design
I don't know the space well enough, but I think the missing piece is that YC 's investment horizon is typically 10+ years. Not only LLMs could get massively better, but the chip industry could be massively disrupted with the right incentives. My guess is that that is YC's thesis behind the ask.
jaxr··on Kagi Assistant
I've been trying out the new Android app. I know it's still beta, but it sucks big time. I'm a fan and paying user of kagi, just wanted to point that out in case any kagi developer is reading :)

among other things, it randomly says I have no connectivity in an awful modal, I click to search and the keyboard doesn't open, I hit "enter" to search and nothing happens (I need to tap on the search suggestion). pretty bad so far. will try it again in a couple of weeks to see if there is any progress...

jaxr··on Panic at the Job Market
What type of coding interview do you find more valuable for the interviewer? Algo code interview always looked like the interviewer trying to show off to me. Guess it depends on the requirements of the job, though...
jaxr··on Iconography of the X Window System: The Boot Stipple
Wow, I could have written that exact comment myself. Those were the happy startx, after you got the monitor sync rates right. The myth went that if you got them wrong, you could fry the monitor. I remember that suse package came with a couple of pins. one tux and one suse chameleon. I preserved them for a long time. But I moved way too many times. Fun times. Thanks for the nostalgia:)
jaxr··on Show HN: Flox 1.0 – Open-source dev env as code with Nix
Exact same experience here. Been fiddling with nixos for quite a while, but never got comfortable with .nix or flakes. The base concepts keep escaping my mind, I have to revisit every time I have to configure something new and I just got tired. Issues are difficult to debug and you have to go through very specific commands and a hellish filesystem to understand what's going wrong. I love the concept, but I feel like it just gets too much in my way.
jaxr··on Cloning a Laptop over NVMe TCP
Today a new nvme is arriving and I need to do EXACTLY this. Thanks Mr poster :)
jaxr··on From engineer to manager: what I love, what I hate
How would you define that one great manager? What personality traits, behavior, skills made that person stand out? I'm curious as I'm getting more managerial responsibilities.
jaxr··on What it was like working for Gitlab
You have more control on the data. Isn't that why you self hosted it in the first place?
jaxr··on Good DevEx increases productivity. Here is the data
Disclaimer: didn't read the paper yet. But the assertions are "Feel X% more Y", which is hardly hard data. Seems like the methodology was just interviews?
jaxr··on Ask HN: What side projects landed you a job?
Why is that? I recently bought a Sonos after getting plenty of recommendations. Even though it sounds great, I hate that they dropped support for Google assistant. Also, the Sonos voice commands can't handle Spotify or YouTube music. Kind of sucks.
jaxr··on Tinnitus linked to undetected auditory nerve damage
Exact same experience here! particularly, if I move my jaw backwards with my jaw muscles, the tinnitus would get worse. Never better, though. I do feel the same sometimes, that doctors are not listening hard enough to what we are saying. I've been suffering tinnitus for 20 years now, and it seems to be getting even worse. I really hope a viable treatment is found in my lifetime. It would improve my quality of life so much!
jaxr··on Titled Tuesday Cheating
I'm not sure that translates very linearly. Most of the chess YouTube "stars" are not even GMs. Most of the viewers are hardly good players, so what you can learn from an IM is astronomical. Charisma and good at teaching are much better skills than a 1000 ELO difference imo. To your point, beating Magnus might drag a lot of people to his stream.
jaxr··on Darling: Run macOS Software on Linux
As a long time Linux user, it's always felt kind of unjust that all good Linux software is ported to other os, but there is no reciprocity. I do understand all the nuances, but Apple and especially MS seem to get a lot out of the GNU/Linux ecosystem and give very little in return.I would appreciate using some open source software released for Mac in my Linux desktop. Thanks to the developers of this project! Will give it a spin...
jaxr··on Sam Altman, Greg Brockman and others to join Microsoft
That's a completely new take for me on how things went down. Thanks for sharing.
jaxr··on No "malfeasance" behind Sam Altman's firing, OpenAI memo says
Sounds like a discussion that can be held maturely, and evolve in the course of a couple of months, with the board trying to settle the argument, or putting pressure on Sam to leave. The MO just looks ridiculous.
jaxr··on The costs of microservices (2020)
Agreed. isn't that why strongly typed languages made a comeback?
jaxr··on Grasshopper – An open-source Python library for load testing
Is there a well established python stack for load testing and profiling? Like, I would like to load test a python web application, then use some analysis tool to understand what part of the stack is eating the CPU cycles and/or RAM.
jaxr··on Internet in a Box
Thought the exact same thing when I saw the title :)
jaxr··on Show HN: Homemade rocketship treehouse – hardware to custom OS
Just curious about the reusing old radios. I have a similar project and could use some inspiration:)
jaxr··on How Postgres Triggers Can Simplify Your Back End Development
Wasn't this something that Oracle pushed aggressively like in the 80s or 90s and then everyone agreed it was a maintainability living hell? Is this a thing again for some reason I'm missing?
jaxr··on Nvidia Unveils CuLitho: A “Breakthrough in Computational Lithography”
Curious to know which Spanish "blend" you are most accustomed to... For me it was like instant ROFL.
jaxr··on Joint statement by the Department of the Treasury, Federal Reserve, and FDIC
Who scrutinizes the banks they make business with? To me, that is exactly the role of the regulators. Make sure the banking system is sound, and if you get the license to run a bank, you do it under certain rules that will protect depositor's money. I don't see how depositors should be held responsible in this case. And worst of all, you are actually punishing depositors who trusted the bank and the banking system, versus the ones that caused the run. Which in my view are also not to judge, since they were only protecting their assets.
jaxr··on Couples who meet on dating apps are more likely to divorce (2021)
I almost see this as a positive thing, if true / confirmed. Divorce is not by itself a bad thing. My life definitely improved in many ways after I divorced. I probably remained in a somewhat toxic environment longer than I should have because of social pressure.
jaxr··on Building a Startup on Clojure
Probably worth bringing to attention the python paradox essay: http://www.paulgraham.com/pypar.html
