kinow··on Fold-... and Monoids
12 years after I created r/functionalprogramming, and the post with this video is still the top submission on reddit https://old.reddit.com/r/functionalprogramming/top/
kinow··on Ask HN: Those making $500/month on side projects in 2024 – Show and tell
On my wish list, maybe for christmas! (I think I added another recent course too, compilers?). Obrigado!
kinow··on Making Your Connection Bad
Sounds useful for some tests that I have to do this week for a bug at $work. And looks like `tc` works with Docker too, to avoid messing with my local wnv, e.g. https://medium.com/@kazushi/simulate-high-latency-network-us...
kinow··on Sci-fi books that you may never have heard of, but definitely should read
I learned about TWI and pirate aba some months ago, and binge-read the whole series non-stop.
kinow··on First scientific study of the Paris catacombs
>The project is now in its third year and the team will produce the first preliminary findings before the end of the year. Charlier predicts the work will outlive his career.

Excited to see what will come from this study over the next years, this was my favorite place to see in Paris last year, and wasn't too hard to schedule the visit (I think I booked one or two days before). Some sections are closed, and I read the catacombs are not fully mapped. Wondering if they will find something or someone long thought to be lost down there.

kinow··on My free book "Rust Projects – Write a Redis Clone" is out
Have you reached out to Tim? I know him and I believe he wouldn't do that intentionally. Maybe he is busy with something else or just lost track of the schedule.
kinow··on A FLOSS platform for data analysis pipelines that you probably haven't heard of
CWL has a loops extension now that can he used for your example of convenging algorithms, https://cwltool.readthedocs.io/en/latest/loop.html

And most workflow systems that support loops/cycles could be used for that too (e.g. Cylc, ecFlow, Prefect, Orchesta/StackStorm, Covenant, etc.).

kinow··on Ask HN: Resources for Learning Graphics Programming
I thought about Pikuma's courses when I read the title. Glad it was already mentioned here!
kinow··on Navigating Anaconda Licensing Changes: What You Need to Know
I'm trying to digest the changes as my company does research, but I believe it is not officially a research organisation (something with how Spain recognizes research organisations).

conda is still open source, but I think the Anaconda distro and the Anaconda channels have changes, based on number of people in an organisation (200 people threshold)...

kinow··on 18 Months with a Framework 13
I replaced my old Thinkpad T530 that has been my daily machine for software development (Python, Docker, Java, workflows, some HPC work) by a Framework 13 AMD about two months ago.

So far everything worked fine. I've limited the battery at 60% as I work with it plugged into power most of the time. I use earphones most of the time, but when I had to use the speakers they were alright.

Camera, keyboard, and trackpad are good too (better than what I've been using). And I haven't had any issues with the monitor hinges (not sure if lucky, or newer batches have the problem fixed).

Once my CPU fans got really excited with some containers and kernel upgrade running in parallel, and wouldn't go off. I restarted it (I had a decent number of tabs open too, to be honest), and then it quieted down.

I limit the CPU performance as I use it for programming (have IntelliJ, WebStorm, and PyCharm open at the same time sometimes, with Firefox with 20 to 40 tabs, and sometimes containers running in the background, and SSH connections to servers. Everything works fine. If I open Blender or something else like a game, then the fans definitely wake up and kick in.

But otherwise very quiet, and the performance is good enough for me. It came with the latest bios installed, and I had no issues installing drivers (Ubuntu 24.04, and using XFCE BTW, everything working OK). So, so far a happy user.

kinow··on Ask HN: What are you working on (August 2024)?
Looks amazing, I was having fun with cssdoodle, and now I have two cool sites to do some programming+arts.
kinow··on Ask HN: What are you working on (August 2024)?
Sounds interesting! I have a projector I use for tracing art, never imagined it could be used for sewing too. Good luck!
kinow··on Ask HN: What are you working on (August 2024)?
I just aggregate everything on Git and found that it works so far. Although some listings (short stories, movies) are growing a bit too much for simple files. What's the lowest level database/filesystem you have to store your data?
kinow··on Ask HN: What are you working on (August 2024)?
Looks interesting! Haven't done any sailing since leaving Auckland, but here in Barcelona there are also quite a few sailing yacht clubs. There might be some serious market for this. Good luck!
kinow··on How the OCaml type checker works (2022)
I don't know if there's any reason like a project, derived language, or some new feature. But there are always posts and comments about OCalm at https://old.reddit.com/r/functionalprogramming/. So it's not really a surprise to me that it gets some waves of posts every now and then.
kinow··on I found an 8 years old bug in Xorg
Interesting feature! Wish I had that option on my devices, combined also with something similar for sounds.
kinow··on How to minimize your exposure to microplastics
Thank you!!
kinow··on Unlocking the Duron and Athlon using the pencil (2007)
I remember doing that back by the beginning of 2000s, unlocking one processor, and losing another identical one trying the same (guess I went too far ahead). I didn't work, and my father was not really happy to have to buy a new CPU because of some graphite (but he understood the curiosity!).

Interesting, I managed to open the other IDs I found here, but yours gives me a very broken web page: https://icq.im/22861316/en

I wonder if you had some ASCII characters, or those old custom-font-and-special-characters texts we used to use?

kinow··on ICQ will stop working from June 26
You should keep trying. Looks like your account was not deleted, but check if the name/description matches what you had the last you remember - https://icq.im/4125222/en
kinow··on ICQ will stop working from June 26
I was trying a few old passwords, but looks like my account was deleted, probably due to inactivity.

I saw someone commenting about accounts being deleted due to inactivity, so first I tried to find a way to search old accounts. Found in a website this link: https://icq.im/$YOUR_ICQ_NUMBER/en

Replace that by your ID. I checked some of the IDs in the comments here, and you can see the user name. But mine just shows [deleted], and the old description I wrote years, and years ago :-)

Searching I also ended up on this icq.com web page, that looks right out of Geocities: https://icq.com/cf/ate/externals/ma00b.htm

No idea what's that tool, and no way I am downloading it. But it's amazing to imagine what would be the "created" and "last modified" stats of the files being served there.

Thanks ICQ.

kinow··on Why you can hear the temperature of water
I thought I wouldn't be able to tell the difference, but when he told me to pause the video to try to guess, I listened to the audio of pouring water again, and thought about "which one sounds like when I pour tea", and that way I could identify the warm/cold water. Interesting!

In case anyone is interested in how the author creates the illustrations, here's his video "My visualization tools (my Apply Keynote setup for visualizations and animations)" https://www.youtube.com/watch?v=gSPRxJLxIHA
kinow··on ESLint v9.0
I migrated a small project few hours ago and their docs covered most of what I needed. The linked post here has a link to https://eslint.org/docs/latest/use/migrate-to-9.0.0, but earlier today I used only this page: https://eslint.org/docs/latest/use/configure/migration-guide

> What about Asia?

e.g. "How Well Does the ERA5 Reanalysis Capture the Extreme Climate Events Over China? Part II: Extreme Temperature"

https://publikationen.bibliothek.kit.edu/1000149226/14910548...

>The conclusions are as follows: the original daily temperatures (mean temperature, maximum temperature, and minimum temperature) can be well reproduced by ERA5 reanalysis over China. ERA5 tends to exhibit more misdetection for the duration of extreme temperature events than extreme temperature intensity and frequency. In addition, ERA5 performed best in the summer and worst in the winter

But even in Europe the dataset can have some issues, e.g. https://www.mdpi.com/2073-4441/14/4/543

> Comparing ERA5 with the other two datasets, ERA5 temperature presents more extreme temperature and small outliers for regions southern of 40° latitude and less extreme temperatures in areas over the Black Sea. In Scandinavia, ERA5 temperatures are more frequently extreme than the observational ones

There are more articles like these on how well ERA5 captures temperature/wind speed/etc, or certain global events, extremes, anomalies, etc., in different locations and time, but I couldn't find more for your other questions (on mobile).

kinow··on Climate Pulse
Pinatubo erupted in 1991 and affected global temperature in the next years [1]. Adding 1991 and -3 to +3 years to the plot should show the trend change.

> Huge quantities of particles from Pinatubo's tall ash cloud injected into the global wind system in the stratosphere. These particles affected the weather in two ways. Tiny aerosol droplets reflected sunlight away from Earth causing cooling at the surface. Scientists observed a maximum global cooling of about 1.5°C. Sunsets and sunrises were more brilliant because of the fine ash and gases high in the air.

I wonder if artists painting pleinair before/after the eruption would show the intensity change of sunset/sunrises in their work too.
