jnsie··on Electricity prices in France turn negative as renewable energy floods the grid
Potentially ignorant question. How does this impact the consumer? Do they actually get paid/credited for electricity used?

jnsie··on Brain-Health Benefits of Weightlifting
I mean, you're effectively saying if things require less time and effort while providing the same benefit then more people will do them. Surely this isn't surprising?
jnsie··on Designing a Lego orrery
The author describes their experience with this set

> Two years later in 2024, Lego released their own orrey design. I was quite excited at the prospect of an official Lego orrery, but I was disappointed by the execution....

jnsie··on Ice – open source menu bar manager for macOS
Thanks for flagging the sale of Bartender. As a long time user I had no idea and am saddened to hear the new. I'll be switching to Ice or another open source tool immediately.

While I see your point (and largely feel the same way) I suppose the other side of it is pull requests. Nice to enable the community to provide supplemental software development.

Same. I'm the guy who would have order Bitcoin with pizza, guaranteed.
jnsie··on Ask HN: What was your most humbling learning moment?
Been there with longer term trades. Bought some DXCM back in 2014 and sold later for a small profit. Was trading at $8-9. I used their continuous glucose monitor (am type 1 diabetic) and was certain they would be successful. Sitting at around $115 a share right now.
jnsie··on Ask HN: What was your most humbling learning moment?
I'm curious as to why you stopped (feel free to tell me to mind my own business!)?

> We are talking small numbers (maybe losing 15k in total) but an amazing amount of time and energy spent doing all this which generated a lot of stress.

This was roughly my experience too. Stopping after the above trade meant my total losses were not huge (relatively speaking; maybe $2000) but I put an incredible amount of effort into it and the stress was huge. I don't fully regret it because, frankly, it was very exciting, I had a lot of fun and it was extremely interesting trying to predict the ebb and flow of the market and the psychology behind moves.

jnsie··on Ask HN: What was your most humbling learning moment?
Like many other people who should know better, I tried my hand at day-trading. I bought some course by someone who in hindsight I'm certain made more money off selling courses than they ever did off of day-trading. I got my account setup, had enough funds to allow me to trade short timeframes (I forget what this was called but there is a rule where you need X amount of money before you can do more than Y trades in Z timeframe) and was excited to trade short and long equities. I had some success and some failure with fees effectively eating my profits. I used to do my scans at night to know what I was planning to look at upon market open where there tends to be a lot of volatility and (I'm sure if you knew what you were doing; I didn't) opportunity. One morning I was certain that Boeing was going to plummet so I shorted a very small number of shares and was glued to the screen. I placed my market order, it hit, then Boeing immediately ripped upwards. Now, if you've traded you know that the difference between going long and going short is that going long you can lose everything you invested, going short you can lose everything you own. For about 3 seconds - my heart pounds when I think about this - I hemorrhaged money. I was down a couple thousand dollars before I could hit the key to cover the short at a huge loss (thinking back I know I had a stop loss but am not sure why it didn't trigger. Presumably it was a limit order and the price jumped the bid pre- and post- spike; I don't know). Right as I went to cover the stock dropped back down, as quickly as it shot up, and I ended up making maybe $500 on the trade. My last ever trade. I withdrew my funds and closed my brokerage account immediately thereafter.

There were so many learnings it's hard to know which is the most important, but I know that I am not cut out to day trade, I know that shorting is a fools game for (most?) non-institutional investors, I know that if it sounds too good to be true ("day trading will make you rich!") then it is and I know that even people of regular intelligence (I'd be average give or take) can do really stupid things. Never again. Never again!

Beautiful!

jnsie··on UI elements with a hand-drawn, sketchy look
Absolutely love Balsamiq. So quick and easy. IIRC there used to be a post-processing tool by a 3rd party that would turn Balsamiq Mockups into code - wonder if it's still kicking around.

Edit: it was called napkee. looks like it was open sourced but hasn't been touched in almost a decade

jnsie··on Drawings depicting gladiators among latest discoveries at Pompeii
This story was also posted on CNN [0]. The following quote annoyed to an unreasonably degree:

> They show that even children in ancient times were exposed to extreme violence. “It does not seem to be a problem only of today, between video games and social media,” Gabriel Zuchtriegel said in a statement about the latest discovery.

I get that video games can (but do not have to be) violent but the fact that they mention video games and social media and neglect to mention active shooter drills in US schools, the 24*7 news cycle, other media (movies, tv), etc. makes it sound like Zuchtriegel (the director of the Archaeological Park of Pompeii) has an agenda. I truly believe that people who do not enjoy video games look down on them and gladly use them as fodder when the opportunity arises. Sorry for ranting.

jnsie··on Escher's "Balcony" in Lego (2002)
I'm right there with you. Thought that the lego build would replicate the warp effect without need for photographic trickery. Was disappointed.
jnsie··on Show HN: I've built a macOS app for developers to clean their dev machines
That is very good to know, thank you. I can't imagine the intersection between devs who need this and devs who would pay for this versus scripting it themselves is that large. But who knows [shrug]
jnsie··on I gave my time and expertise to StackOverflow because it was licensed CC-BY-SA
> How does removing their code help anyone?

The same way protesting anything helps anyone. It draws attention to a problem and, if the protest is visible enough, leads to positive change.

jnsie··on FDA recalls defective iOS app that injured over 200 insulin pump users
As a matter of interest, are your issues on iOS or Android? No real reason for asking beyond curiosity...
jnsie··on FDA recalls defective iOS app that injured over 200 insulin pump users
This is a bit of a wild jump. OP hasn't even explained their grievance with the software.
jnsie··on FDA recalls defective iOS app that injured over 200 insulin pump users
I think you're greatly overestimating the problem. The only action a user can take in the app is to give a bolus. This is a relatively (1-2 years?) new feature that I believe necessitated FDA approval. Everything else is surfacing information (blood sugar levels and notifications) to the end user.

Edit to add: Utilizing a telephone is a significant quality of life upgrade from my (and many other) end-user experience. I'm guessing you are not Type 1 Diabetic (apologies if I am incorrect) in which case you have no idea the number of times in a day that one checks their blood sugar, boluses, etc. Frankly, it's exhausting. Being able to dial in a bolus or view my blood sugars from my phone, versus pulling out my insulin pump, has a significant impact and provides significant benefit.

I moved to the 7 and have no issues with the (iOS) software whatsoever. What issues are you having? If I had one issue with the 7 it's that it appears much more impacted by bluetooth interference than the 6. I suspect that this is a hardware, not software issue.
jnsie··on I created 3,800+ Open Source React Icons (Beautiful, Rounded Style)
These look great. I'm a bit ignorant on the topic - what makes an icon a 'Reach Icon'? Can these only be used in React apps? Am I missing something fundamental?

jnsie··on Disney unveils the HoloTile floor
Super cool but I'm guessing a long way to go. Notice that nobody lifts their feet when walking on this. I'm not sure if it's fear (those small careful steps conjure images of people ice skating for the first time) or if the tech doesn't work well in that scenario.
