If it even gets that far. I’d almost be willing to take that bet, but 5 generations for this device could mean more than a decade so I don’t think any of us can say for sure.

All that said, I haven’t read the full review yet and I doubt it’ll do anything to convince me, but still I appreciate you writing it up and putting it out there. From what I’ve read so far it looks well thought out and it clearly took some effort, so kudos.

For those who wear N95s on planes, I can confirm that 3M Aura 9205+ works great with Vision Pro※ and doesn't hinder using it at all, nor reduce comfort, at least for my head and face shape.

You're right, its pretty common for the wealthy to try and trick poor people into feeling sorry for the wealthy actually paying taxes on things.

As my other post pointed out, tons of things have multiple layers of taxes. But the things people suddenly have some big moral issue with "double taxation" are things like estate taxes and corporate earnings and dividends and capital gains.

Few people bat an eye at us double taxing the low income nicotine addict. Everyone seems to want me to shed tears for the billionaire having to pay "double taxation" on their third vacation mansion they're inheriting.

Argue the rates are too low or too high for a given transaction. I can get behind that. But just crying because there's two different taxes being applied to a given transaction? Really?
It’s worth speaking in terms of energy not just heat. Sunlight bouncing off a reflective curtain and going outside is one of their benefits.

An awning is a net benefit over a curtain alone, but there’s overlap in functionality so having a curtain reduces the net saving from adding an awning.

Ask HN: Books on Selling $1M Software Services Contracts
Patio11 has written extensively about selling oneself as a software consultant. (That is, a solopreneur soliciting contract work.)

However, there's a process for selling the services of a larger development team to firms with budget for $1+ million software services needs.

(For example, $1 million to have six people build an app and backend.)

What would you recommend as the best books to learn the latter?

That is, books that explain how to sell "contract software development" to organizations with sufficient budget?

I'm asking for a friend. Not joking. :)

I haven't found any really detailed numbers for the project. Does anyone know more about how heavily subsidized the housing is, meaning how much the public bill will be each year?

The idea that such projects are so popular and aren't necessarily meant to help only those most in need is confusing in what is usually considered somewhat of a free market. Why aren't these types of projects being built privately if they are so successful? And how do you justify subsidizing housing for those making at or even above the average household income level?

No housing is maintenance free. Sustainability means you repair things that break, apply paint every year years, when someone discovers the next lead is bad you replace whatever has that. This has always been the case and always will be. Some things need more maintenance. some things are purely cosmetic and can be skipped to save money. But there is always maintenance needed.
> You look at Linux's syscall table[0], read through the documentation to figure out the arguments, data types, flags, return values, etc., and then implement that in your kernel.

As well as some subset of the files expected in /dev, /proc, /sys, and similar, which are also part of the userspace ABI. And the startup mechanisms for processes, and the layout of AUXV...

It's absolutely doable, but the interface is wider than just the syscall layer.

People get plenty mad about sales taxes double taxing taxed income, too. Nobody likes paying taxes.

Reading about this situation here and elsewhere, I have to wonder how much of this is even legal. Pre signing contracts? Refusing to accept terminations? Not making payments but taking in money? Do they not care because they’ll get to dismiss all these in a bankruptcy proceeding?

It also seems like these shutdown CEOs may be running the company in a deceptive way towards a shutdown. Is that really legal? Can’t they face criminal charges for that, and wouldn’t that remain even with a bankruptcy case?
This is the main reason I see to get a vision pro - basically a travel friendly monitor. Glad to see it does well under these conditions, though it's still a tough sell considering the price tag.
Aside from the Meta integration which will always be a non-starter for me, it would be great if Quest and other headsets followed Apple's design with an external battery pack. I wonder if there are/will ever be "dumb headsets" that are powered/ran by a phone.
I've maintained a fairly popular open source project for over 13 years[1]. The software is basically "complete." How does funding work for someone like me? I have no initiatives with it that require funding. Occasionally, I need to fix a bizarre obscure bug, or support a new python version/feature (async/await being the last big one). But otherwise, I just field questions a few times a month.

Truth be told, I'd rather be done with the project completely. It's like a little monkey on my back that I can never be rid of, that I must always tend to. But at the same time, since I can never realistically receive funding for it, the only value I get is the fact that my name is on it. I wish a big, legit company would just buy it off of me somehow, but there's no incentive for them either. I don't know how this ends.

>The more time passes, the less I can shake the feeling that the world would be better if we tuned out of our environment less.

Depends on what environment that is. I mean, is there some value in hearing an ambulance siren at full volume while I'm walking down the street? Or the sound of people trying to get my attention to hand me some flyer? Or the sound of the BART?

I take out my earbuds even saying Hi to the bus driver I can't imagine talking to a flight attendant while wearing a VR device. It seems very uninterested in the person you are talking to.

Could be just me but I think a lot of older generations share this experience. It is not hard to take out your earbuds or take off your VR device to show you are paying attention to the person you are talking to.
I guess the flip side of this is that you look like a fucking dork.
Honestly, this is the best thing if it changes the worst experience I've had cancelling something - Gyms. They make it crazy easy to sign up, but a pain in the ass to stop being a member (for example, if you move and forget to cancel good luck - they want you to come in and talk to the manager in a lot of cases)

Anyone can borrow against their own assets: house, car, stocks, cash holdings, 401k, even their expected earnings (e.g., college loans). They can even borrow against nothing as far as they're trusted (e.g., credit cards).

> Do you pay attention to the people who win at Russian roulette more than those who lose?

Well.. no since you cant really win anything. With pharmaceuticals on the other I hand I think 1 Oxycontin/etc. like “situation” would be a reasonable price to pay for let’s say 4 major successes.

You were talking about decades. Surely you noticed the advancements in treating cancer, HIV and a multitude of other conditions since the 90s?

> This was a lie.

Sure. But it’s on the same level as saying that filtered cigarettes don’t cause cancer. If a doctor actually believes that he’s just too dumb to be a doctor… (although I assume most safety claims were relative to other opioids and not in absolute terms?)

Are there any signs that the situation with Semaglutides is that similar? Yes they are new and not well understood drugs (well not really but sort of..) and it’s not inconceivable that their longterm cost might end up outweighing the benefits but I don’t really see any signs of an actual conspiracy yet.
I like Modern C. I have reviewed it favorably in several places. I agree it is intermediate.

> Your source says a crash every 70,000 miles for 17 year olds, to my understanding

Correct.

> Number of unsafe actions that would warrant a disengagement, but didn't happen to cause a crash, would likely be significantly higher

Why? When I’m in a Waymo, I’m taking a nap or entirely uninvolved in the driver nearly 100% of the time. I am worse situated than a drunk, high teen because I’m in the back seat and not even pretending or trying to pay attention. And that’s Level 4. If you’re marketing Level 5, every intervention should be treated like an autopilot failure in aviation: more than we do for crashes.

If I’m in a car with a driver where I need to regularly grab the wheel to keep them from colliding, they’re an unsafe driver.
> The countries in turn can require that services in those countries must support Firefox, or perhaps specifically ESR versions of Firefox.

The countries can also trade that support for features that might not be in the best interest of its users, such as introducing closed blobs to the code, "benign" trackers that allow government oversight of surfing, breakage when using VPNs, etc.

People could fork those browsers if the code is still open, but look at how many people use Floorp, or Vivaldi.

I feel it's akin to government support of journalism.

I’m not a working while travelling kind of person (I often have the ambition to work while flying, but for some reason I always feel too tired); my Vision Pro stays in my bag for the duration of the flight. For work when away from home more generally, however, I find it a fantastic device. It’s basically a portable Apple Studio Display that I can use wherever I go. As someone in a long distance relationship who is often away from home for long periods of time, this is extremely useful.

TidesDB – High-performance, durable, transactional embedded storage engine
Hello my fellow hackernews community. I hope you are all doing well.

I'm Alex a super passionate and driven engineer who loves building database systems and data structures. I've created a new open-source database engine called TidesDB. TidesDB is a log structured merge tree based storage built for high-performance written completely in C++. Still in it's early stages but moving quite rapidly.

Some features:

- Embeddable storage engine

- Variable-length byte array keys and values

- Simple API (Put, Get, Delete)

- Range functionality (NGet, Range, NRange, GreaterThan, LessThan, GreaterThanEq, LessThanEq)

- Custom pager for SSTables and WAL

- LSM-Tree data structure implementation (log structured merge tree)

- Write-ahead logging (WAL queue for faster writes)

- Recovery/Replay WAL (RunRecoveredOperations)

- In-memory lockfree skip list (memtable)

- Transaction control (BeginTransaction, CommitTransaction, RollbackTransaction) on failed commit the transaction is automatically rolled back

- Concurrent safe

- Tombstone deletion

- Minimal blocking on flushing, and compaction operations

- Background memtable flushing

- Background paired multithreaded compaction

- Configurable options

Do let me know your thoughts, advise, I'd love to hear what you think.

Thank you.
Total construction of wind, solar, energy storage, and nuclear globally over the past decade is what the market is saying and it’s saying it very clearly.

Individual participants making different bets is how the market decides what’s effective and what’s wasteful. But you can’t assume any subgroup is speaking for the total market, because they could be about to lose big. Nuclear could make a huge comeback in the coming decades, but until that happens we can only talk about the market in terms of what the market is actually doing.
I agree, but I think Modern C has good, structured recommendations that make it worth getting through at least once.

Solving symptoms can be helpful, especially in a trauma care type situation, but do you view the lack of housing as the root cause?

Getting people under a roof can definitely help stop the bleeding, but the more important question is how to help solve whatever it was that led to the problem in the first place. If it really is as simple as a lack of available roofs, that would be a very simple problem to fix with all of that Bezos money.

Oh no the terrorist/murderer wouldn't like this gadget :((((((
many angles on this current news items -- one that is worth mentioning first, echoes what others have said here.. these professional archivists are the "most expert" at a certain task at a National scale! yet the words "expert archivist" plus black-box corporate run, remote software is on full display, very likely heading towards "doing the job" of these most trained people. And to add insult to injury, in a certain task the success rate of 90% is declared "good enough" when these are people with years of training to never, at all, perform at that low of a level.

Draw your own conclusions about the professionalism and goals of management, emboldened and empowered by "scale" ..

As a counterpoint however.. vast and rapidly expanding knowledgebase is a unique and pressing concern of the modern age. Even world-class, PhD laden and disciplined groups are not keeping up with ingestion and use of the amounts of data emerging. The cure adds to the ailment here, though.. AI itself in current incarnations produces mountains of gibberish or worse, half-truths and half- very plausible and confident nonsense.. This is an important story.

It has never been easier to create your own company if you have the proper grid.

Reduce your workhours to half day or 80%, spend your evenings and weekends building.

Show your demo around to get more money if your progress is slow.

But technology has never been as accessable as it is today. You have a lptop, a server costs you 50$, a big machine perhaps 100 or 200 / month.

The problem are people who think just having an idea is the main part of creating a product/company.

I have more ideas per day than non technical people and i could make 50% work. Not unicorn work but making enough money for a company money.

Its just a lot nicer to work from mo-fr earning good money and having time for living.

There's a nice synergy between data center operations and nuclear power. Similar requirements for high reliability, complex systems, redundancy, even things like electrical grids and cooling, and industrial HVAC are crossover points

In other words, a lot of engineers could work quite happily in both fields.

Not necessarily. The grid of the future needs a plurality of solutions, one of which is clean baseload (e.g. hydropower, nuclear fission, or fusion).

However, don't discount renewables. Paired with energy storage -- which isn't only chemical batteries! --, intermittent generation can be extremely useful across vasts parts of North America.
