Especially the 1 km square receiving grid.

They say the energy would be like standing in the sun. I'll bet there is more to it than that, like cancer or radio interference or other unknown nonsense.

But... wonder what a solar array 1km square would receive from the sun itself?

Honestly, I'm reminded of moving across states. When I went to move, every pound of stuff had a price, like .50/lb. So I could figure out if something was worthwhile to move. If something weighed 200 lbs, it had to be worth $100 just to break even.

In the same way, how much energy would we expend to get those solar panels into orbit, and how much would the receiving array cost to build in time + real estate. Would it break even compared to expending the same amount of money on the ground?

like if launching an array into orbit + ground station was $10b dollars, how much ground-based solar could you get for $10b dollars. And with batteries? I'll bet the economics of ground-based is pretty good.
Some of these are obviously stupid and deserve to be ridiculed, but I don’t think this site needs to be as hard on the “one laptop per child” one as they are. That seemed like a well-intentioned product designed to do good in the world, not everything ends up working out.
My ten-year-old Apple developer account has been locked by Apple
Hello Hacker News community,

I'm reaching out for advice and support about a crazy situation with my Apple Developer account. I've been a member of the Apple Developer Program since November 2013, paying the annual subscription fees to maintain my small website's free app on the App Store.

I recently forgot to renew my membership and when I attempted to log in to resubscribe, I was greeted by a message stating that my account was locked. They said I could ask for a review to unlock it, which I did, but I then received an email about 12 hrs later saying that the review was unsuccessful. I contacted Apple Support by phone, only to be told that my account has been permanently locked and cannot be restored. The app is important to my users, and I am desperate to find a solution.

Has anyone else experienced something similar? Any advice on steps I can take or contacts within Apple who might be able to help? Your insights and suggestions would be greatly appreciated.

Thank you.
Yes, I have dealt with this and am still dealing with this, and much of it it all came down to early childhood trauma and how I needed to survive situations as a kid. I ended up that I had a pretty extreme amount of dissociation and symptoms of PTSD, and after grappling with literal decades of therapy and many diagnoses I started looking into dissociation, from which things truly clicked into place and finally I had a model to understand how I worked. If you have memory issues, please check in about CPTSD and dissociation - it’s not well known and it’s been life changing for me, and it’s massively undiagnosed compared to people who have them (6% of the population has one).

With the help of therapists and peers I have been able to figure out how I work and make progress on things I haven’t been able to for much of my life, after dealing with a spate of pretty extreme burnout. There’s no telling what your journey might hold, but I can say with experience that it is possible to figure out what underlies the hangups that have been hamstringing you.
Well, plenty of people were born after that whitepaper came out.

Sure but you turning it off doesn't occur in a vacuum. Slack is a communication program. Either it then has to disregard reactions from other people, which is potentially a situation where someone will acknowledge your message and you will not be notified of that fact, or they then have to simply prevent reactions on any messages you yourself send, which is going to prompt a question from the coworkers using the space. Which brings us back to, "Why?"
Isn't that somewhat of a survivor bias? People with ADHD on stimulants would typically have little to no side-effects because if they had moderate to severe side-effects, then I doubt a medical professional would keep them on stimulants.

I treat my ADHD with stimulants, and I would say there are definitely side-effects, but the side-effects are mostly manageable.

While I do benefit from stimulants, I personally believe the benefits are exaggerated, and apparently the Cochrane Library does not disagree with me:

They pull data from all kinds of things now.

For example, satellite imagery of trucking activity correlated to specific companies or industries.

Its all signal processing at some level, but directly modeling the time series of price or other asset metrics doesn’t have the alpha it may have had decades ago.

> Why not just let people do what they do with other files and leave it on their desktop.

Once upon a time, upon seeing a disk image open with an app icon, a certain quantity of people would choose to run the app straight off the disk image, likely not understanding the prompt to copy the app to the Applications folder.

Then, sometime later, the disk image would be unmounted (e.g., system reboot) and suddenly the app they had “installed” disappeared.

Rather than force everyone into mandatorily copying apps to the Applications folder, they added a dialog to suggest to the user where the app should go. I will say, though, I didn’t realize it applied to _everything_ outside of the Applications folder. I thought it was only for apps run off of disk images.
The author seems to make the assumption that manipulating a downloaded ZIP file is more “intuitive” than a disk image. I could have written the same article with the opposite assumption with equal validity. (Some apps arrive as a disk image INSIDE a ZIP file…no idea what those people are thinking.)

There is a long MacOS history and evolution here starting with “you run the app from the floppy disk it lives on”. The disk image with the handy Applications alias makes perfect sense as the end result of that evolution, if you just know what a disk image, an alias, and the Applications folder are. I mean, the arrow even literally tells you what to do. Unpack a ZIP file and it just sits there.

There was a discontinuity in this history when the App Store was imported from sandboxed iOS device world where none of these mechanisms are present (well, now there’s Files, but that’s hardly the same). It tries to hide the entire mechanism from you and does a pretty good job — just press “Get” and run the app from the Launcher, just like iOS.

None of this is “intuitive” but some of it may be more or less familiar and/or make “obvious” use of mechanisms you are expected to understand (like folders, disk images, ZIP files, and the App Store).

The message here may be that the prevalence of iOS means Mac users shouldn’t be expected to understand folders and aliases. Maybe so, but there has to be some baseline knowledge of what the direct manipulation is manipulating, or the whole GUI exercise is pointless.

(BTW, totally agree with Windows users being gun-shy, particularly if they’ve experienced the fragmentation-grenade style Windows installers that are still around after multiple decades of Microsoft trying to rein developers in…)

Since the Bipartisan Safer Communities Act necessitated this rule change, shouldn't you be mad at Congress?

Further (emphasis mine):

"Despite that concern, there have been at least a few overreactions to this rule online, with some commentators making dire proclamations about the criminalization of all private gun sales coming from this rule. That is not exactly what this rule does. Many of these changes apply to administrative and civil actions by ATF, rather than criminal actions. Being sued by the ATF and facing civil or administrative fines would not be pleasant, but it would be less terrible than being in federal prison."

I don't have a dog in this fight, so I had no idea what you're upset about. This article was the third hit in my noob search. Apparently you oppose informing the state (CLEO) about private transactions.

Okay.

There are ~430m guns owned privately in the USA. With ~15.5m/year sold (new and used). The updated rule covers, what, ~30,000/year transactions, less than 0.2%.

That's what this whole fight is about? Really? A decades long slap fight over 0.2% of sales?

I'm struggling to think of a hill that I'd personally die on (rhetorically) where the stakes were less than a round-off error.
The irony is that they are developing tools to allow people to work from literally anywhere. This is all about petty bureaucratic control and expensive office space.
Let's say your day job is providing a website on which paying customers can upload images.

Youre currently only supporting jpeg and png.

Your objective for a quarter could be to broaden support.

So you'd plan to add 10 additional formats. If you add 8, you've achieved your goal. Makes sense, right?

Honestly, the snide comments are spot on. It was even dumber then SMART SCRUM, aka development via waterfall, which is totally agile xoxo
Great summary.

I believe the answer is to have a single model of everything.

You can build the model from whatever: Draw it with a GUI, query your server infrastructure, analyze binaries, collect it from databases, parse it from documentation, process your issues, etc. The important points is to merge all the information into a single model.

You cannot represent this model on a screen in any meaningful way. Instead you can only get certain "views" into it to understand an aspect or answer specific questions.

Does it exist today? Many tools and processes have been developed to achieve it. For example, "Model-based systems engineering" is a very formal approach. I have yet to see it realized in practice though.

I'm pretty sure it isn't a single tool or process though. By definition it integrates with nearly everything and that means a lot of customization. You won't get it get it off the shelf.
All of it has to go tremendously right for that to be the point where it breaks.
I would probably just send the emote I would react with as a single-letter answer. If I have nothing to say beyond "thumbs up emoji" the fact that you don't like reactions doesn't, by virtue of your opinion, give me anything more interesting to say in return.
> Or am I totally wrong and the chips are always at the limit of the contemporary technology?

I can chime in here. There are many things that determine the feature size.

There is the process limit, yes, and if your needs are simple digital logic, that's often going to be the density limit.

But if you need NOR flash, there's a stability limit around 40nm process node. You can use smaller transistors for everything else, but soon the NOR is most of the chip.

But what if you need a 1 Amp FET in your PMIC? Well, that won't shrink with process node at all, so maybe a cheaper process node is better to use.

It really depends.
How is corporate power derived from government power? Corprations usually exercise all the power they can until govt reins them in.
Yeah, I need to make a simple spreadsheet and try and figure it out.

The problem is that the risks are high: the usual figures are less than 1 in 10 businesses succeed or that a 30:1 payout is the minimum sensible financial payout (VC figure).

Winning is hard even though we don't have a CGT. Marginal tax at 39% doesn't encourage marginal business building. And once you have the house and the bach, the marginal utility of money drops for an individual: the marginal happyness from the next million is a lot lower than the first million (also see "income satiation"). The discount rate, and the personal cost are other huge factors, and the average person doesn't like a financial winner.

Investing money and time in a high risk activity like starting a business is not fiancially sensible from what I have seen. We do it to chase status, not because it makes sense on a spreadsheet.

Imagine world class education, for everyone, accessible to all at the price of Netflix. AI can be a teaching assistant, but also makes it easier to create course materials. Generating video explanations, infographics etc.
I used to code in Ruby for indie games (well, RPG Maker). For me the reason is several things:

1. Its performance meant that it would never survive against Java/C# for AA/AAA games, not to speak of C++

2. Lack of libraries. Last time I tried no physics engine worked with Ruby 2.3, and ouch that made my game or many games impossible

3. No significant advantage over Python, especially given that for indie games Python had the popularity advantage, the numpy/numba/Pillow/easier to write high performance code advantage. Bitmap manipulation in Python using even numpy is much easier than whatever I can do in Ruby.

4. OOP is not actually that important especially for the market Ruby can break into. DragonRuby is in the right step, but look at pico8, love2d, or even Unity3D -- there is not a lot of inheritance going on. Simplicity is good.

Of course the above factors play into each other.
> why not get other people to read the lines out to you?

Among other reasons, that I didn't think it would help. Getting someone else to read it does provide the possible benefit of hearing emphasis and inflection. The downside is that it becomes difficult to go back and re-read a difficult passage. My uninformed guess is that the cumulative result of this is approximately a wash.

I can't bring myself to write this with a matching degree of sarcasm.
I'm sorry, but you wrote this post. Did you self-teach writing?
DevRel is just a transient phase during ramp-up. Once you get market dominance, you squeeze the independent developers by controlling their platform access and pricing, and keep all the high-revenue products for yourself. See Apple, Microsoft, Google, etc.
Mostly other languages like Lua and Python also being good choices.

Lua is simpler, is much, much easier to embed into your project and is much faster, especially with LuaJIT. It is the perfect fit for this task

Too much OO can hurt performance quite badly and while some form of OO is common in the game industry there is also more emphasis on keeping things simple. Ruby is a very nice language and not a bad choice for non-performance critical code but Lua is the default choice for game scripting for a reason.

And for the cases there Lua is too simple, well there is Python. Sure Ruby does a few things better but it doesn't really have a clear advantage over Python while also being less popular.
Fascinating, will check this out! I wanted to focus on Python first to build this quickly, test out ideas and iterate.

This seems like a good option for a switch.

Do you know if any of these can run on Apple/Android devices?
What is the baseline performance of the LLM in solving those programming tasks? And did you test the performance of the students in the Codex group at the end of the course without allowing them to use Codex? Essentially I'm asking how can you conclude that these students didn't just learn to call a LLM, but actually learned to code independently?
Design flaw in civil courts. Wright was backed by billions of dollars of other people's money that he was willing to throw away, so he was able to drive up cost for others and consume court time.

You’d be confidently incorrect.

I’ve been involved in the negotiations. Pharma companies pay a couple basis points for it and are happy to walk away otherwise.

It’s not a kickback, it’s fee for service. In fact there are specific Safe Harbor rules for this type of payment to avoid kickbacks.
They very well may! Unfortunately, since our approach to teaching how to learn is flawed to the core, it results in peoples' ability to learn being compromised from the very beginning, requiring them to build their knowledge base and learning approach on shaky foundations.

The way to correct this is by imbuing students with the confidence and skills required to learn (according to their style of learning) correctly from the very beginning, so that they build on solid foundations instead.

Right when FiveThirtyEight launched, they did a brilliant piece of content strategy in that one of their very first pieces was a quest to find the best burrito in America [1]. Anna Maria Barry-Jester self reportedly "traveled more than 20,000 miles around the United States and eaten 84 burritos in two rounds (to say nothing of the dozens of extracurricular burritos I polished off)."

I was glued to the series as it plodded on week by week and it still sticks in my mind today as simultaneously the best and worst job in the world I could imagine. Part of what made it so enthralling to read was this grand act of human perversity that a single woman would endure such a gruelling quest for such a trivial question and she made you feel that perversity along every step of the journey.

Because the insurance company don’t pay list price, they pay the negotiated rate.

The patient doesn’t pay list or net price they pay the co-pay. There doesn’t need to be price transparency. It’s like auto-insurance - do you need to know the negotiated rate for your collision repair?

No, you just pay your deductible and move on.

The list price is irrelevant to the insurer and the patient.
I swear this is entirely earnest. That example works. Except:

Congress is elected by and serve at the pleasure of the American people.

Public servants in Executive agencies are appointed at the pleasure of the President and his Cabinet as applicable, with some appointments requiring Senate confirmation.

It is therefore "removing democracy" to task unelected public servants with writing laws and regulations. The task of legislating is the duty of the legislature, Congress. The Executive Branch's job is to execute the laws as legislated by Congress, hence their name.

>Logistically, how many laws would Congress have to pass each year to have a functional society just to keep up with research and industry developments?

More than now but less than what would be humanly impossible. Make those fucking Congresscritters earn their pay and votes.
I had the same reaction. The product also existed and represented some interesting developments for the time tbh.
> Why does probability seem to follow an arrow of time, it doesn't seem symmetrical like the rest of physics.

One cannot really oppose probability to "the rest of physics". Probability is not "a part of" physics. Probability is what we use to describe imperfect knowledge of a physical system - and we know more about the past than we do about the future.
> For maximum efficiency you'd avoid addc like hell, because it blocks internal precomputation, and use guarantees like he did, avoiding overflow better.

Whether that is the case depends on the CPU. I hit memory bandwidth limits before adc becomes a problem. But I concede that you have a valid point and that there are definitely cases where leaving sufficient space for carries is the better strategy.

Anyway, we can probably both agree that "% 1000000000" is not the best way to do it.
I read your comment as:

> Why is it X and not, y'know, X?

Is there something central to what a business is besides the way communication happens within it?
addc makes all your adds serialize on the flags register, which is really painful.

more modern approach is to reserve some bits out of every word for carries, but that drastically complicates things.
Yes, have you?

It’s pretty clear high performing company don’t maintain it.
If you have short time-series with low variance, noise and outliers, strong prior knowledge, or limited resources to train and maintain a model, I would stick with simpler traditional models.

If DL is a good fit for your use-case, then I tend to like transformers or combining CNNs with recurrent models (e.g., BiGRU, GRU, BiLSTM, LSTM) and optional attention.
