CPU coolers are tuned for 300 watts cooling at a delta of 60ish degrees centigrade (100ish Fahrenheit).

You'd be operating at a much lower delta, split over two coolers. At best, the transfered power would scale with the delta, due to tuning it might scale worse.

I think you might be better off just skipping the heat-pipes of cpu coolers and using aluminum plates positionned in both airflows.
CPUs need heat-pipes because the heat source is sooo small. Here your heat source will be much bigger, especially in terms of surface area.
If we can predict lightning in an area, can this lead to an alternate source of energy? What are the contextual, technical difficulties for implementing such a system?
it's not scary wording if people _need_ the range to commute or to have peace of mind. there _are_ considerations needed for the EV transition and many people don't know much about voltage at all so it's important to share that.

i just bought an EV and am super keen about it, but it's important to be educated.

Most box fans will struggle with a single filter right up against them. The blade design on a typical box fan is designed for velocity, not pressure. Also, I don't know the physics as to why, but you want to be pulling air through the filter rather than pushing. It's why car radiators have the fan on the engine side.

The best setup is to use multiple filters arranged in a box shape, since more filter surface area = less restriction on air flow.

There's some great examples here:

A typical microkernel will have user programs that drive the hardware that expose a very similar interface to what a macrokernel would provide, from the application level there isn't a whole lot of visible difference but at the system level there is, essentially the macrokernel is broken up into a number of separate processes each of which is fashioned as a 'normal' user program. This significantly reduces the scope of the kernel itself which has a whole pile of interesting implications which usually manifest as massive reliability improvements over macro kernels, a penalty in raw io throughput and the ability to elegantly (on the fly) load and unload all kinds of OS components without the need to reboot the system.

But there usually is a clear distinction between such 'kernel processes' and user applications, they also tend to be run at a slightly higher priority to ensure that the system keeps moving.
Again, you are misunderstanding me. Asahi Linux is doing a lot of hard work and open sourcing that. That in turn enables porting back some of that software to OSX. Steam on Mac so far runs without proton so it can't run a lot of things. The people developing Asahi Linux are doing a lot of hard work figuring out all the low level details of how the hardware platform works. The resulting software could be adapted to run inside of OS X. The hard part would be reverse engineering the hardware. Which is exactly what they are doing. And with the wide distribution of macs, it's obviously attractive for Valve and game studios to target that platform. Apple is responding to that threat by offering game studios an alternative.

Google famous for being so particular about having data to justify their decisions, even down to the color of blue in the css.

Do they have data to back this move up? Data that suggests that WFH is less effective?

Or are they just annoyed that their expenditure on office real estate is being wasted?
It sure does feel like most anti-office people do complain about multi hour commutes and being stuck in traffic or whatever. That is very much American issue.
i wanted an EV sedan/not suv and didn't really want a tesla. the options were mustang mach-e, tesla m3, cheyy bolt, gmp (hyundai ioniq / kia ev6) but tbh there were a lot of tradeoffs between each car. i don't need 800V charging, i'm pretty anti-elon, and the mach-e was too slow for L2. i've driven in an ioniq and just wasn't a big fan.

then i discovered the bmw i4 and fell in love, bought one, and am glad to say i made the right decision. the driving assist is legit awesome and the car feels just like a regular 4 series
When you’re putting input into the bike at lean, it won’t wobble. The wobble is a progression that starts with a lightly loaded front tire, and every bike I’ve ridden with a good quick front suspension geometry will wobble in the right circumstance. A steering damper will kill the progression of a wobble, but if you’re accelerating the front can still give a wicked shake on a bike with a damper. Enough to loosen the front brake pads, smash thumbs, etc.

When racing, if you have a hill crest that you’re accelerating over and you set the front down after the hill, it’s common to get a good shake. You learn to ride through it.
> Careful of the municipal utility bait and switch! Here in Idaho they recently adjusted the net metering credit to greatly decrease the value of solar energy.

As other have said, people taking the bait changed the economics, and that forced the switch. To be fair, it was foreseeable.

Here in Australia we have the worlds highest rooftop solar take up. Feed-in rates are plummeting like a stone. It's not hard to see why - most days when the sun is shining brightly, the wholesale price of electricity is negative. Look at SA here at midday (the picture will change tomorrow): https://aemo.com.au/energy-systems/electricity/national-elec...

We do have plans here that expose you to that wholesale price. If you export electricity when the price is negative, you pay the grid.

Ironically, at the same time this over supply is happening all states that mainly use coal have been hit by a price rise this month. I got mine today. In 22 days, the price of my electricity is going up 45%. That mainly caused by renewables (and particularly solar) making the old coal plants uneconomical. They used to be able to sell power 24 hours a day. Now since they can't ramp down quickly they have to pay the grid to export their excess power during the day. I don't know whether that's the cause, but right now we have gigawatt coal plants shutting down years earlier than they said they would five years ago. Which is how we get a 45% price rise.

So we are in this situation where feed-in tariffs are worth nothing, electricity prices are going through the roof, we are throwing away a ton of electricity we can't use during the day and solar installs are slowing down.

The solution is storage, of course. Batteries were hard to justify price wise a few days ago. But after this 45% price rise changed that. Again it's a double whammy, but in reverse this time. Remember during the day the price goes negative. That means the grid pays you to charge your battery. I would not be surprised if for a while, the return on a battery will be higher than installing solar panels.

Which means the next phase of the renewable change over has hit us with a vengeance in Australia. It's the invisible hand of the market finally directing investment where it's needed most I guess. It arrived a little late, and it's not so much a hand as a fist. We would have been better off building storage a few years ago. And again, that was foreseeable. Indeed it was foreseen by numerous published articles. But who reads learned engineering articles on future electricity tariffs? Not your average noob looking purchase roof-top solar apparent and if the people hawking solar panel installs read them, they didn't mention it.

So here we are. We wanted an energy transition. Now we've got one, ready or not.
In addition to Mastodon as the other poster mentions, Signal (obviously not a business tracking/advertising users) will require a mobile number to sign up even after usernames are rolled out, all in the name of spam prevention.
It's easy to build a PC with known-to-work parts. And then it does work fine. Those parts are not particularly expensive either.

I'm writing this from my 2nd Hackintosh. And hackintosh is my daily driver since 2013. Including for iOS development.
Their loss
I'm still sceptical of passkeys. Either there needs to be an easy way to generate multiple ones, e.g. having multiple devices that can login. Or it should be easy to export and import them. I don't want to my account to be bound to exactly one specific device of mine... or to need to rely on some cloud sync provider (like Apple or so).
As a San Jose resident, let me tell you, San Jose is just really big boring suburban town. It's not a city, no matter what the sign or the population is. There's no downtown. Like sure, there's a place called "downtown", but it's empty, even when SJSU is in session, and when it's not, it's even more of a ghost town. It's not even a good university district. Sure downtown Willow Glen is okay, but it's no different from Castro Street in Mountain View or University Ave in Palo Alto.

Most of San Jose is just tract homes, office parks, strip malls, and parking lots.

The worst part of San Jose is that there's absolutely zero culture here. Like none. Anything interesting in the Bay Area, it's in SF.
I had this problem with Dashlane after they suddenly changed their policies, though with a regular password. My solution? Out of frustration I developed my own password manager. Eventually I was able to recover the password from my email provider though. But at that point I had no more nails left.
It is called a Cosri-Rosenthal box [1]. I've built three variations on these using different kinds and sizes of Filtrete filters they are very cheap and effective.

The downsides are that they take up a lot of space, are a big eye sore and awkward to carry and move. They also can make a lot of (white) noise on high, which can mask sounds you want to hear.

They're great for special situations like wildfires or out of the way areas like basements where looks don't matter.

For common living spaces we use Coway Airmega AP1512's which are relatively compact, auto cycle up and down fan speed and are much more attractive than DIY stuff.

It's 90% the commute (and the time lost in commuting, especially if you need to set up your gear), and only 10% actually being in an office. I have been fully remote 10+ years now while everyone else was at the office in a city I moved from, so that's the worst of both worlds: people don't need to be social on Teams/Slack, they are social by the coffee machine. But I'm not at the coffee machine.

The pandemic was a huge improvement. Suddenly everyone was remote. So it's definitely improved. In a perfect world I'd be very happy to go to an office one or two days per week and have meetings, be social. If the commute was 5 minutes rather than an hour, then I'd be happy to do it 3-4 days a week. But I don't think I'd want it to be 5 days even if I could walk there in two minutes.
Before M1, Hackintosh was giving top-tier performance for 3-4x less money. With a day's worth of research. And then an hour here or there when doing yearly upgrade.
Sprawl of providers due to forks for whatever reason is a completely different issue to the resource sprawl you originally called out.

The point remains though: there’s no incentive system for the people who make the implementations decisions re resource granularity within providers to increase that because of this pricing change. For the most part they don’t work at HashiCorp. And even when they do, those abstractions are more often due to the underlying API they’re communicating with.
Positive pressure does 'one shot' filtering. All air in the house goes through the HEPA filter once. Hence any spores (or other patrickes) that get filtered, get filtered immediately. Though spores (or particles) that make it through the filter get to linger indefinitely.

It sounds like a good filter and PPS would meet your goal.

How to Launch a SaaS
I'm going to launch a SaaS web app. Here's my plan on getting to launch.
If I were to commute to my companies nearest office it’s about 1h20 or 60 miles.

Let’s assume I moved to near that office and lived in a high density area away from nature and dark skies. What does my wife do, who now faces an 80 mile commute the other way?
> Secondly, all of the examples above were examples of trying to avoid reality.

1) What makes reality important?
2) What is the definition of reality?

> In all VR spaces you will absolutely be the product while also being milked for every single micro-transaction you can pay.

How does that differ from reality? Are you not paying for the walls that are presumably around you right now?
Wow the live feed is fun.
>Data that suggests that WFH is less effective?

If you even have to ask this, you haven't interacted with many normal people working from home. Homes are full of distractions, especially if you have small kids. I bet your normal young dev with small child at home (even with their spouse taking care of the kid) does half as much work as they could have had they been at the office.

Yes. yes. offices have brain drain in form of small talk and whatever, but at least you in a different environment and detached from your home. And yes there are some people who have the luxury of separate home office and if you dont have kids then that could easily be better for you. However we aren't maximizing only you but your team, your department, and ideally whole company.
> IIRC /r/music isn't planning on coming back.

Same for me_irl I believe.
Oh man, that's a clbuttic mistake!
I love it when the office is extremely cold. Makes me active and focused. I can always wear a jacket if I want to be warmer. On the other hand, if you set the temperature too high, some people will be unable to make themselves comfortable no matter what.
It's still a thing. It will die off in few years. But it's going strong for now and I'm happily hackintoshing. I saw reports that upcoming MacOS Sonoma beta version is already running on a hack.

I wouldn't build a fresh hackintosh today though. M1/2 Mac mini has sane pricing/performance ratio IMO.
No one flagged the post. It was killed by a software filter until users vouched for it.
> How many users do these apps have?

There aren't that many projects that have "millions" of users.
I get a feeling in america it’s

Work want to move me off an hourly wage. Which is fine, but it means instead of being paid time and a half for every hour over 35, I take 1.5h in lieu off.

If I do a 90 hour week you’ll barely see me for the next three weeks.
Maybe they should focus on launching ANY successful product since 2009?!
From what I know, this holds for air purifiers. Quantity of air moving through matters more than quality of the filter, because of re-circulation.

The cool part of a PPS to me is that, because it is a one-shot system (no recirculation) it can actually take advantage of high quality filters.
All of the above. Sometimes the system you need to change was written six years ago by an intern from another team that was defragged, in a framework that isn't supported anymore, and everyone keeps piling the tech debt higher.

Some parts of Eng are mind-blowingly incompetent. Google is remarkable not for "hiring the best people" but for how widely the quality varies by org. Some orgs have a reputation for incompetence.

Security and Privacy is a great example. Half the org is fanatical about protecting users, smart, effective, the works...and the other half is fanatical about ticking the right boxes on their forms and putting roadblocks in front of product teams because it makes them look important. Try getting something done when someone from the second group is paying attention to you, and yeah, it'll take nine months to launch a settings page.

Yes, there's bloat, but it's not as simple as "there are too many people so MMM ruins your productivity".
The American Fotoplayer
Survey design is really interesting to me. Did they add a control question? Something like "Justin Bieber is a giant squid" and all of the responses for anyone who answers "yes" get dropped.
I can't speak to FileVault, but Bitlocker and TPM can be quite easily defeated through sniffing the bitlocker key as it's transmitted from the TPM chip to the CPU to decrypt the drive on boot over the LPC, I2C, or SPI bus. Unless you enable TPM+pin for preboot auth you can't easily protect the data on a Windows PC, even with FDE.
Is that the reason? I thought it was just more of a Erdogan nationalism thing
This is the best description of suburban hell I’ve ever seen expressed on this site.
Startup mentality - you preparing to serve 100M users even if you have 1.5 right now and it will be rare luck to have even 1M because if you will not hit high numbers it doomed: high investment will not bring equally high returns and everything will be scrapped.

As we all know, we don't know what C-4 is trained on. It might be trained on information they didn't have the rights to use (for example). This is why they might be so tight lipped on how it was produced.

Google on the other hand, has much much more to loose here, much bigger reputation to protect, and may have built an inferior product that's actually produced in a more legally compliant way.

Another example would be Midjourney vs Adobe Firefly, there is no way Firefly makes art as nice as MJ produces. Technically it's good stuff, but it's not as fun to use because I can't generate Pikachu photos with Firefly.

People have stated that ChatGPT-4 isn't as good anymore. My personally belief is this is just the shine wearing off what was a novelty. However it may also be OpenAI removing the stuff they shouldn't have used in the first place. Although there are reports the model hasn't changed for some time so who knows.

I guess in time we'll find out. Personally I don't really care for either product so much, most of my interactions have been fairly pointless.

I think it's just fun to watch these big tech companies try deal with these products they've created. It's amusing as fuck.
Okay so found this from MIT website here:

The problem is that the energy in lightning is contained in a very short period of time, only a few microseconds. Further, to obtain that 1 million joules, one would have to handle a voltage of several million volts.

But even at 1 million joules, the typical lightning strike contains only about ¼ of a kilowatt-hour of power, which is not enough to make much difference on our electric bill.
Do you realize how you took a kind and genuine comment, made the worst possible interpretation out of it and completely derailed an otherwise interesting thread.

From the HN guidelines -

Please do better next time. Glad that your current thread has been flagged and disabled by the community.

It's a terrible question, yes. Too long, lack of definitions as you said.

Still ... my experience with this generation is that they are hyper focused on "safety issues" and don't really have an understanding (yet) for how the tools built for those things can be perverted into a dreadful weapon.
Genuinely curious, but why didn't you?
Didn't the project gain enough visibility before you noticed this post, or was there any other reason which would be helpful for others to know.

I will say. I'm gonna be burned for this here, but... yeah I can tell that remote is far less effective.

As a worker I like it! And there are some positives - mainly, you don't have to commute and live in a cheaper place. But as a manager, I see that it's just so far less effective, and I see how much more we can do it we meet together once in a while. One thing that's good is that it gives you access to a bigger talent pool, and you can pay people less, because they are happy they can work remote.

I was originally against hybrid, because it's not really one thing or other thing, but now I start to see its positives too.

I only use https://www.sharpconsumer.com/home-appliances/hg40el/

It runs silently at lowest and humidifies the air too.

It uses one container of water per day.

I filter the tap water so it doesn't clog up the filter.

I disable the ionisation feature which makes particles stick to the walls and furniture.
For people who use Home Assistant, I've gone with DIY route with ESPHome [1] and senseair CO2 sensor. You can buy those sensors for +- 26 USD on AliExpress. Together with 5 USD, ESP32 devkit, it's mostly "solder"-n-play.

Of course, I only have one of them, so I can't say if they are accurate, but I just need to know if the CO2 levels are normal (+- 400ppm) or high (+1000ppm), to open a window. I have tested it with just blowing on it, the CO2 value jumps up, putting it near a window, goes directly to +- 400.

I haven't had any strange readings with it, ESPHome developers really made an excellent product, that is stable and "just works". You can even calibrate the sensor by putting the it outside (but I haven't really bothered with it).

ESPHome has also support for a lot of other sensors that you combine on a single ESP32 module.
