Show HN: I built a CPU cooler/Peltier-based Airconditioner for 48v Solar
I've been building a Peltier with 48v solar in mind. Part of the design constraints were to create it using only commodity CPU cooling tech I could buy online, and plenty of trips to the hardware store.

Initial test run in the window to track cooling ability (which I expect to be fractional of a full compressor AC). This run using 110v mains power for consistency and testing. I've already run 48v, I just didn't want to be swapping batteries all day (and I need to improve my battery discharge safety features).

Runs around 200W (measured using Kill-A-Watt), COP is much lower than compressors, but I think it might actually be enough to take the edge off a warm room. The goal here is to have solar panels outside the window like shutters, and the unit running without any additional inputs... storing any excess power in batteries for night time operation. Low visual footprint as well, so it doesn't block the view.
No reason was given for the status change.
If you scan everyone, the prior probability is the rate of occurrence within your population. So the test has to be more sensitive than that. For things that have an occurrence of less than 1%...
Microwave with knobs: put food in and turn the knob to the time you want. maybe turn the power knob if necessary, and wait for the ding

Microwave with buttons: put food in, stare at the keypad for 30s looking for the "just f**ing microwave it" button, give up, start putting in a time, realise you need to put in a power first, work out the appropriate power in percent based on the excessive power of the microwave, put that in, figure out the expected format for the time (60 or 100 for one minute?), put that in, press start, wait for the interminable beeping, have to go and press a button to shut it up when you're busy with something else

An exaggeration, but most button microwaves have at least one wacky and annoying issue in their UI, and i've experienced all those problems separately. The panasonic inverter ones with a convection oven are worth tolerating just for the quick yet crispy baked potato option, though.

> applying Adobe Lightroom presets (image filters) on many images quickly and cheaply

This sounds to me like a thing people might pay for.

But I would (strongly) guess most photographers don’t know what an “API” is or why they’d want to pay monthly for one, or how to wire up “curl” to it somehow. People who know that stuff will cobble this together in a script.

As a simple desktop app I could see a utility like this doing well in that audience though. $29-49 one time payment, apply all the presets you want, save lots of time.

Does excitatory/inhibitory map cleanly on to the higher level abstractions? I'm no neuroscientist, so maybe it does, but that seems like a bad assumption to me because in digital logic "active when low" is extremely common. A spurious-suppression system that caused inhibition when low would be perfectly reasonable and compatible with the observation that excitation caused an increase in spurious behavior.
Kyiv seeks US approval for missile strikes inside Russia – WH source
any art or music class that is successful in reaching its students will probably change what you think, how you think it, and gradually should change what you feel, how deeply you feel it, and to what extent you can analyze and converse with those feelings you have.

If that sounds like intellectual activity above the level of qualia, the same is true for something as simple as the taste of food. We learn what apples taste like by tasting lots of apples and tasting things that aren’t apples and reflecting on and focusing our attention on experience of apples.
If I were to mention a fourth it would be him but he's a bit embarrassed about all the controversy about his ideas on consciousness and doesn't really discuss them in depth in any videos I've seen, or wade into heated discussions about the nature of reality.

Way too early to say, better to wait and see
This is so wrong and all FUD. At my company R users write modular packages and deploy them to internal CRANs while python users write scripts and email them because it is way easier to write modular code in R because R favors easy on ramps for new users while embracing good ideas like immutable semantics and functional programming. Further, R has targets which is way more general than snakemake. Even from a reproducibility perspective, R wins hands down. Getting an R package into Guix is trivial compared to a python package. This means that in 10 years, more R code will still run than python. It really saddens me to see the level of dishonest crap which goes unchallenged to make an inferior prototyping language kill the only lispy language with good numerical libraries.

Extremely controversial opinion, stop reading now to preserve your sanity: If you can’t afford engineers, you probably aren’t ready to hire engineers. If you can’t develop a product without a VC cash drip and a code monkey goon squad to get shit done for you, you probably aren’t ready to run a company.

The Ethical Founder Community – Use Cases Anyone?
Hey friends!
As founders, we have certain values and we "assign" some for our companies as well. For some of us it's inclusive hiring, respecting the privacy of our users, building our projects transparently and listening to our users' requests.

I'm starting a new community (as a side project currently), to share use cases about founders and companies who value the power of values.

Can you think of any interesting use cases? Maybe even your own?

Please comment here or send it over to hello@theethicalfounder.com
I think a simpler and more logical law would have been to disallow the sale of products which are locked down beyond their owners wishes. It's a net negative for society when we add additional production steps to decrease the usefulness of the things we produce.

So any computer (phone, tablet, laptop, desktop, watch) would have to allow installing whatever software the user wants. On the hardware level.

That would mean alternative OSes like Linux could run on any computer.

It would still be allowed to ask or even warn the user "Do you REALLY want to install an alternative OS?" but not to ultimately deny it.

Mosaddegh was a marxist, supported by Russia, who tried to play both sides to advance a personal agenda of Persian ascendancy. Had he not been overthrown, the Russians would have eventually lost patience and killed him; or the radical islamists would have eventually overthrown him with the assistance of regional Arab players not keen on an ascendant Iran, with Marxist leanings. They would've wrongly believed an Islamist Iran would be easier to align than a secular/marxist regime.
> the planet will continue to have multiple climate zones

Yes, but large-scale crop production is not so easy to move.

> it won't take a planet-wide crop failure

Yes, by "planet-wide crop failure" I didn't mean that there won't be a harvest anywhere, just that production will drop low enough that there is no more surplus. I'm pretty sure that will be enough to destabilize our geopolitics, and it will be all downhill from there for quite a while.

Why are you doing this? No interviewer is going to look at this or maybe even understand it. After 11 years (assuming you are around 35), you'll probably be interviewed with someone younger.

I didn't find Github helpful either in the last 2-3 years. Culture has shifted and now it's about jumping leetcode like platforms and scoring highly on them. Then bullshitting your way into the interview.

If you are strictly tied to front-end, you may want to look out for different options. The front-end market is by far the worst struck and is super tight. I also, most importantly, don't think it's going to be better anytime soon and it's going to get much worse from here.
I worked at a place where I can say, FusionIO saved the company. W e had a single Postgres database which powered a significant portion of the app. We tried the kick off a horizontal scale project to little success around it - turns out that partitioning is hard on a complex, older codebase.

Somehow we end up with a FusionIO card in tow. We go from something like 5,000 read QPS to 300k reads QPS on pgbench using the cheapest 2TB card.

Ever since then, I’ve always thought that reaching for vertical scale is more tenable than I originally thought. It turns out hardware can do a lot more than we think.

I have been trying to move away from Google for a long time. Kagi is what finally made that successful.

About 6 months ago my browsers default reverted to Google for some reason (probably something the IT department pushed out). I didn’t pay attention to the page header and when my eyes jumped down the page I physically recoiled at how bad things were. Bad results and useless junk everywhere. I looked up and saw it was Google. I truly don’t know how anyone still uses that site and considers it good.

I feel spoiled used Kagi. It’s so good.

> If a modifier is defined by the fact that it modifies the actions of other keys, then left and right modifer keys modify the action in exactly the same way and thus are the same modifier. Common sense indeed.

No, that's nonsense and factually wrong. Common sense is that a different modifier key is still a different modifier key even if the modification is the same. You have to do some logic twists not to make it so. Also, this is factually wrong: they don't modify the action in exactly the same way, that depends entirely on your config. In mine they act differently

> And if you want to reference windows, a platform kitty does not support, here you go:

But your overly confident overly broad statements weren't platform limited. So how are your links to the backward platforms / gui frameworks relevant? I've already acknowledged "state of bad defaults"

> a terminal keyboard protocol has to work on all platforms not just windows.

And if you turn your mental barrier off, it's pretty obvious how to make it work everywhere - you simply flag both left+right on getting the no-side flag info on a backward platform that doesnt differentiate. And only flag either left or right on a platform that does differentiate. Or differentiate it yourself by reading raw codes. So there are no good reasons to create yet another bad keyboard protocol when it works fine without blinders off

> The good lord alone knows what windows does, probably synthesizes that state based on press and release events.

Do tell me, what is the alternative magic of how Mac/Linux synthesize Shift state without press/release events?
> ought to be provided at cost (base rate of interest) through central banks

In all financial instruments risk & return are intertwined and inversely correlated. If the mortgages could be provided at the base rate of interest that would imply they have zero risk. But mortgages do have some risk, although a very low one compared to e.g. buying stocks, so the rate is necessarily above the zero-risk rate.
We’ve been teaching values based leadership for over a decade via EarthPilot.org

It’s a hallmark of legendary leaders.

One mistake groups make is to say these are our values and expect people to follow them vs. identifying the actual values of the people who have come together.

You don’t tell people what to value, you explore what the deep values are and then incorporate those into decision making.

> "For months" is surely an exaggeration?

Not where I live (San Francisco Bay area). It was literally months. Fortunately, we always buy in bulk and had a pretty good supply in stock when it hit the fan, and I was able to get resupplied through Amazon once. But lockdown happened in March and it was May before I saw a roll of TP on a shelf again, and then stores were limiting purchases for many months after that.

Yeah, that's what everyone said. But I couldn't find industrial TP either, either in person nor on-line.

> The commission is appointed by the member states, which are all, supposedly, democratically elected

Yes, that's what they say, if that's "democracy" then we certainly have a different understanding of it.

> Please, enlighten me how it was not the people of the EU who put them there.

Take 8 out of 10 people (and I'm being generous here) off the street and ask them what party they represents them in the European "Parliament" (which is not really a parliament, the same way as the Democratic Republic of Korea is not all that democratic), they won't be able to tell you (I certainly won't be able). As per the European Commission, asking them that would be futile, see my point above.

More generally speaking, this policy of putting one's head in the sand and shouting "I can't hear you! This is a democracy! The European Commission actually represents the will of the European people! Saying otherwise is vile talk!" when the European electorate starts noticing facts for what they are wont' really help this "European" project going forward, but that's the bed that they've decided to sleep in so it's up to the technocrats in Brussels now.

Wouldn't it cause the cost of consoles to go up and the cost of games to go down, in a way that on average has no significant effect to consumers?

As long as it applies to all companies, why is it an issue?
Yes, but not for the reason you think. In the very near future, most software will have a text input box for an LLM or chat interface. These will be an alternate way of controlling the UI.

So instead of clicking through 5 menus to find out when your last deposit was at the bank's website, for example, you could type, "What was my last deposit?" into a GPT-style box. The LLM would the perform the same actions as the GUI.

I'm convinced this is the future norm for human-computer interaction. It will be both GUI and natural language text.
You may be right, but as a former resident of several towns of a similar size hearing a helicopter almost always meant somebody was in critical care and going to a big hospital.
None of those satellites are also trying to collect as much energy on one side and beam them on the other side. Notice how those satellite closer to the Sun are wrapped into reflective and isolating materials and only antenna, solar panels and sensors are sticking out.

Additionally high power laser has currently something around 80% of efficiency. So if you have 10kW of input from solar array on one side, then you are transmitting 8kW via laser and 2kW into satellite itself as a heat. And again, we are in vacuum of space, so good luck with radiating 2kW of power into vacuum.

The fact, that you can't get rid of waste heat would need whole satellite to work close to 100% effectivity, which we don't have technology today
Depends which people and whose communications. I was in the farmers market of my small rural town this morning and it's funny how all of this simply don't exist here. No smartphones in sight, people are here physically, they interact, buy local food, laugh, have a drink, etc... Then they go eat at some friend's place and have some outdoor activities. On the other hand yes it looks bleak for terminally online people.
