applied_heat··on GraphicsMagick needs some additional productive volunteers
The request for additional volunteers has been in the release notes for every release since 2021.

Poor guy needs to pass the torch!

Pretty sure I used image magic in the late 90’s

applied_heat··on Geothermal power is a climate moon shot beneath our feet
Some Solar and wind farms I’ve seen have capacity factors about 30%, and run of river hydro commonly 30-40%
applied_heat··on Geothermal power is a climate moon shot beneath our feet
The battery installed along solar farms is usually on the order of hours of energy delivery though. Like 5 hours. It’s fine, but not everyone will be able to ornaffors to buy electricity on when it is cloudy and still for a few days.

There was 25 Hz infrastructure in Ontario until the 1950s

applied_heat··on America desperately needs more air traffic controllers
By starting at smaller airports or less busy runways, getting comfortable, then stepping up to more demanding situations.
applied_heat··on America desperately needs more air traffic controllers
Hopefully they don’t throw juniors on to the busiest runways in the country
applied_heat··on 65% of all ski resorts in the US have closed since 1960s (2022)
While lift ticket prices have maybe doubled in the last 20 years, I am sure costs For the ski areas have more than doubled, like You said insurance, but also parts, labour,
applied_heat··on Thank HN: My bootstrapped startup got acquired today
What would you do with $50k that would make such a difference in your life?
applied_heat··on PyViz – Overview of the Python visualization landscape
Wow it’s a big list. My must have features are left and right y-axis, easy zoom and pan with the mouse, and live updating so I can stream data to plots from industrial processes, updating about every 200ms.

I used kst-plot which was really good. I think airbus uses it too.

These days I am not doing any real time analysis only historical, so I am using Victoria metrics with data fed from a wonderware historian and grafana, since working with the wonderware historian directly is painful, and our samples are one every 15s

I’m curious if anyone has used some of these python plotting libraries that might work for my use cases. Thanks

applied_heat··on Sonos CEO steps down after app update debacle
It is Probably just fine for the next 10 years. Chromecast audio are working great for me with my 70’s receiver and modern mini amp and Bluetooth speakers with line in.
applied_heat··on Sonos CEO steps down after app update debacle
Can you recommend a modern mini amp?
applied_heat··on Sonos CEO steps down after app update debacle
I’m still using chromecast audio they work great!
applied_heat··on Sonos CEO Patrick Spence steps down after disastrous app launch
What functionality did Sonos provide that you are after?

I use chromecast audio to play music throughout the house and it works great

applied_heat··on What the TP-Link Ban in the US Means for You
It only mentions routers and not APs. I am extremely pleased with my tp-link Omada WiFi setup with self hosted controller in a docker image. after over a decade using mikrotik and ubiquiti products I don’t think I would go back for WiFi, and I would certainly be inclined to give a tp link router a look if it’s as polished and capable as their WiFi products.
applied_heat··on What the TP-Link Ban in the US Means for You
It’s the verbosity that indicates LLM to me … put the time in and give me the shorter letter
applied_heat··on The consensus on Havana Syndrome is cracking
I read it was caused by pesticides that were being applied extra heavily in the areas around the embassy, inside the embassy, and even in the “victim’s” homes due to concerns about zika virus which were hyped at the time

The link below includes results from a study which included brain imaging and comparing the results with other victims of neurotoxicity poisons

applied_heat··on Starlink is now cheaper than leading internet provider in some African countries
In Canada I am going to threaten changing to starlink the when my new telus fibre comes up for renewal and they inevitably want to double the price, and also I would be pleased to never have to use Rogers again
applied_heat··on World's largest pumped storage power plant fully operational in China
What is extremely novel about this facility is the variable speed pump turbines and dc grid connection for the plant. Hydro plants usually (exclusively other than this one?) use synchronous machines that operate at a fixed speed.

Variable speed hydro turbines is quite cutting edge for an old field where change occurs very slowly and carefully

applied_heat··on World's largest pumped storage power plant fully operational in China
Both the GW and GWh are important and independent characteristics
applied_heat··on World's largest pumped storage power plant fully operational in China
I know it is a typo, but for other readers the figure in the article is 3.6 GW from 12 300 MW turbines, not 36 GW.
applied_heat··on Cable-cutting tanker seized by Finland 'was loaded with spying equipment'
Diesel generators simply use less fuel if there is less load than the maximum.
applied_heat··on Why making friends as an adult is harder
Where in the world do you live? Why is it like that?
applied_heat··on NonStop discussion around adding Rust to Git
Is the proprietary operating system that HP Nonstop uses just HP-UX? If so it doesn’t seem that different from other operating systems that rust can use?
applied_heat··on The slow death of the hands-on engineering manager
For your feature meetings the recipe for success is the same as any meetings, have an agenda and other materials people need to review before the meeting to be prepared to contribute without wasting everyone’s time, and take minutes and distribute them after the meeting, the minutes document the decisions made so they don’t need to be rehashed on the next meeting, and the minutes feed in to the preparation package for the next meeting. It is a lot of work to prepare these meetings and keep them on track, on the agenda items, so that the required decisions get made.
applied_heat··on Why America's economy is soaring ahead of its rivals
After a certain stage, parents are working knowing that the value they are generating will be passed down to their children, it is no longer for them in their lifetimes, but their employer and society still benefit.

If parent’s work beyond what they can spend in their lifetime is not given to the children, who would continue to choose to work? Already in Canada you can exceed 50% tax rate and many adults who could see more patients, write more books, take more cases, do more work, choose not to as the marginal benefit decreases.

applied_heat··on Ask HN: How can I grow as an engineer without good seniors to learn from?
There is a limit at to what one person on their own can achieve, or would want to try to take on in order to have some life outside of work.

You have been given an opportunity to build and lead team, hire the person you would want as a technical mentor. Focus on the big picture results, what will you be able to put on your resume? Built and Led a team that developed a technique/software/product that yielded $x result for company, or “worked on x product in y language”

It’s a different class

If someone who has a successful company wants to interact directly with you, learn everything you can from them, that is an opportunity greater than any tech bullshit
