ljosa··on Ask HN: Who is hiring? (May 2026)
Vivodyne | Senior Full Stack Software Engineer | Full time | Onsite (5 days) SF

Our robots grow thousands of human tissues and test them at scale, so we can predict which medicines will work safely before they reach patients. You will build polished, high-performance web applications using React with FastAPI on the backend and Postgres as a database.

ljosa··on Bose has released API docs and opened the API for its EoL SoundTouch speakers
The speakers have a telnet interface and DLNA support, but no documentation and I was not able to make it work with MiniDLNA in a couple of hours of trying.
ljosa··on The Theatre of Pull Requests and Code Review
`git commit` has a `-v` option that adds the diff to the bottom of the commit message template so you can see it while you write the message.
ljosa··on Launch HN: Hyprnote (YC S25) – An open-source AI meeting notetaker
I just tried this for a standup meeting, and the inability to tell who said what is a show stopper. You'll need to add speaker diarization for this to be useful for more than 1:1s.
ljosa··on Launch HN: Hyprnote (YC S25) – An open-source AI meeting notetaker
Glad you're having fun, but it had the "website with autoplay" vibe.
ljosa··on Launch HN: Hyprnote (YC S25) – An open-source AI meeting notetaker
Why in the world is there _background music_ when I start the app?!
ljosa··on Show HN: Check Supply – Send Checks in the Mail
Don”t most banks offer this exact service for free? My credit union calls it “bill pay.” I use it for exactly the use cases you list.
ljosa··on OpenERV
I think it means that it's like [Lunos](https://www.lunos.de/en/for-heat-recovery). The unit alternates between exhaust and intake every couple of minutes. The air being exhausted heats up a core, which in the next cycle warms the air from the outside. Lunos e2 is advertised to recover 90% of heat and 20–30% of humidity.
ljosa··on Ask HN: What is your favourite keyboard customizations? (qmk,system config)
SpaceFN, so I can hold space and press HJKL for arrow keys.
ljosa··on Norwegian fishermen hunting for halibut caught a US nuclear sub
The US Coast Guard cutter Healy (their largest ship and largest icebreaker) was in the area around that time. (Source: https://www.highnorthnews.com/en/usas-largest-icebreaker-nor...) It would make sense for them to help out.
ljosa··on Ask HN: Who is hiring? (May 2024)
Vivodyne | Senior Software Engineer (Front-End) | Remote U.S.

Vivodyne is a pre-series-A startup spun off from U. Penn. You'll be working on the web interface that scientists use to define studies that our robots will then perform by culturing, treating, and imaging human organoid tissues.

ljosa··on PaperBack: How to store arbitrary data on A4 sheets of paper (2007)
I back up my private SSH keys by printing them as QR codes.
ljosa··on Automakers are sharing consumers' driving behavior with insurance companies
Is there a good source for which makes, models, and model years “phone home”? I would absolutely take it into account when shopping for a new or used car, but I’ve had no luck with Googling.
ljosa··on The Best iPhone
Apple’s battery replacement service is about $50 including shipping. Took a little less than a week for me.
ljosa··on Show HN: Laptop mount for your mechanical keyboard
I just configure Karabiner-Elements to disable the internal keyboard when my travel keyboard is plugged in.
ljosa··on Ask HN: Who is hiring? (October 2021)
Resilience | Frontend, backend, full-stack | Elixir, AWS, ++ | Remote (US) | Full-time | https://resilience.com/biopharma-careers/, email vebjorn.ljosa@resilience.com

At Resilience, we're building a platform for drug and vaccine manufacturing. The company is 14 months old. We have raised $1B and bought several factories, and we're building more. Our first big customer was announced a couple of weeks ago: we are going to be making mRNA for Moderna's coronavirus vaccine.

We aim to replace the expensive, slow process of industrializing and launching a pharmaceutical production process that today is preventing many new therapeutics from reaching the market. A customer should be able to build on our network and infrastucture, similar to how we've gotten used to building on AWS for cloud computing, with full visibility.

I'm a principal engineer on our product engineering team, the group that will build the software we need to make this happen. Hiring frontend, backend, and full-stack engineers at mid to senior levels. The little bit of backend code that we have so far is in Elixir. Remote, must be in the United States.

ljosa··on Use Alacritty instead of Termite
Alacrity works well on MacOS also. It gives you enough control that you can send meta (command) properly to readline, emacs, and whatever else is running in the terminal while letting some command chords be handled outside the terminal (e.g., command-tab, copy/paste, rectangle).
ljosa··on Raspberry Pi for Kill Mosquitoes by Laser
Vertebrates, typically.
ljosa··on IoTaWatt Open Source WiFi Electric Power Monitor
I'm using all the 14 inputs.
ljosa··on IoTaWatt Open Source WiFi Electric Power Monitor
The numbers I get from mine match the power company’s daily numbers almost perfectly.
ljosa··on IoTaWatt Open Source WiFi Electric Power Monitor
I learned that the radiant heat in the bathroom floor used very little electricity compared to heavy-hitter circuits like hot water, so it wasn’t worth adjusting the thermostat schedules and give up comfort.

We use it to keep an eye on how much energy we use for grow lights in the greenhouse.

As a bonus, the electricity usage of the well pump is a proxy for water level in the well.

ljosa··on IoTaWatt Open Source WiFi Electric Power Monitor
I installed it last year. Very happy.
ljosa··on Linux touchpad like a Mac update: Firefox gesture support live in nightly
I put my Apple trackpad in front of my keyboard.
ljosa··on Fish is not operational on a VT220 terminal (2015)
I've always used ISO 8859-1 with VT terminals; there are only a few differences between it and the DEC character set.
ljosa··on This Page is Designed to Last
TFA is written from a reader's perspective: the author had found a bunch of links important enough to bookmark, and then most of them disappeared.
ljosa··on Why the Boeing 737 will never take the place of the 757
> What would it be like on the westbound leg, I wondered — a longer flight, from a shorter runway, in the face of winter headwinds?

Wouldn't colder (denser) air and a headwind make the plane require less runway?

ljosa··on PC Keyboard: The First Five Years
After 20 years of not using caps lock, two things happened in the last couple of years: (1) I taught myself to touch type "properly," and (2) I started using an IBM XT keyboard (the first layout in the linked article) with caps lock easily reachable with the right palm. Now I use caps lock and love it.

(I put "properly" in quotes because many---even most---type in a different way quite successfully. But for me, it really helped reduce the number of mistakes I made. With caps lock, I don't have to mess that up when I write LONG_UPPERCASE_CONSTANTS.)

ljosa··on Elsevier cuts off UC’s access to its academic journals
As a grad student at UCSB, it only took a single email to get formal permission to release all my code under the BSD license.
ljosa··on Clojure at Netflix (2013) [slides]
We're using it happily at Yieldbot. We're an ad network, and the core matching technology (which finds relevant ads based on the contents of the page and decides which one to show and how much to bid) is all Clojure. All the data science stuff is Clojure (it's been great with Spark and pretty good with Storm). The data pipeline is all Clojure now. The central database for ad campaigns and such is Datomic. The APIs for the frontends are moving to Clojure.

ClojureScript never caught on for the front-end work. There are some substantial services for which Elixir was chosen instead of Clojure.

ljosa··on Digital Ocean Managed Databases
I'm not worried my own instance/droplet getting DDoSed, but DO's network being taken offline for days because of a large-scale DDoS attack directed at another customer, as happened with Linode in 2016.
