I am a lifelong proponent of advanced nuclear, and I study it daily and professionally. I can tell you that advanced reactors will not be cheaper, at least at first. Nuclear technology development is challenging and takes time, and is very heavily regulated and NIMBY'd. Proving out new reactors requires in-reactor experimentation, which itself is very expensive and time consuming. Building a new First of a kind reactor is always expensive, and is followed by long test/shakedown periods where heat/electricity will not be getting sold for a large fraction of the time. Delayed revenue causes financing costs to skyrocket.

The small/micro reactors are less expensive from a total investment point of view, but you still are paying at least tens of millions for your core and probably hundreds of millions for your license, regardless of how small you are. The payback on a $100M license for a 1 MWe reactor is infinite.

Furthermore, we've had small/micro reactors in the past, like the one that powered McMurdo Station in Antarctica for 10 years. It was shut down because it was expensive to operate. How do we make sure this doesn't happen with the new gen of SMRs?

We need to be developing reactors that approach full autonomy, somehow design out the need of having 4 shifts of security, somehow design out expensive site-specific licenses, have a clear story for their final waste disposition, are clearly and demonstrably safe, and so on. I'd like to see the advanced nuclear industry focus less on hype and more on practical solutions to these particular problems. Some are working on it, but there's still a lot of seemingly vapid hype in the advanced nuclear circles. I worry that it will lose credibility someday.

Meanwhile if we could figure out how to build Gen III light-water reactors more cheaply, like the Koreans largely have, then we'd have a great low-carbon stopgap that we could deploy significantly, today, with no technology development, and help avoid climate change.

Regardless, we the nuclear industry have to work super hard to get both capital and O&M costs down dramatically if we want to contribute to the energy future.
That's awesome! I love the images and synopsis. One thing I have in the works is a seekbar that stays in sync with the server, but it's actually a lot more challenging than it sounds.

I like how you include the episode and season info. Do you search for that online or have it locally?

Really cool project, thanks for sharing.

> How many would actually be needed to burn up the unused fuel of "regular" reactors? Is there some ration of regular:breeder that would be needed (5:1, 8:1, 13:1)?

Depends on the specifics, e.g. Russia is proposing a 2:1 ratio for a cycle they're planning:

Yes you are right. Someone could argue Java Byte Code is interpreted, but I think colloquially, that's leading people to misunderstand the nature of modern JVMs, which as you say, will choose to either run the code in an interpreted manner, or compile it first (possibly with optimizations) dynamically at runtime. Those choices are made based on what will result in best performance and safety.

Java on the other hand is 100% compiled (to bytecode). And byte code is machine code for a non existent machine. Actually, I think Sun had built machines that could natively execute Java Byte Code. Someone could build an interpreter for it, but I'm not aware of one.
Decouple the environmental controls and electrical subsystem from the engine by using a separate electricity generator with a separate fuel supply. Use deep-cycle marine batteries as a buffer, and have the generator turn on to top them off when they get below a threshold. Meter the power usage for the generator, and charge for distance travelled and by power used.

A lot of owner-operator truckers have discrete electricity generators, because running the engine just for HVAC and electric power causes unnecessary maintenance costs. There are even truck stops that pipe in electricity, HVAC, and video channels through an umbilical that hangs down to one of the windows.

A miniaturized RV that is basically a stripped-down mobile motel room will also have a decent post-fleet-vehicle secondary market, as people buy them to live in full-time, or use more like a traditional RV, excepting that it can fit into a van-sized parking space.

Also, I'd just use blackout curtains or aluminum shutters instead of the electrochromic glass, and use a removable or retractable privacy barrier between the driver compartment and the private space. I'd rather use simple and reliable tech for simple requirements.
Where has that happened?

There are plenty of sites that would be happy to host nuclear, if it were possible to build. Vogtle and Summer are our recent examples, and NuScale is deploying soon too.

NIMBYs have not held back nuclear as much as the industry itself.
Which is odd because tons of applications in the wild already have this amazing capability of directly consuming python and Haskell without first converting to yaml. But of cause you still have the ability to both produce and consume yaml if that’s needed for some reason.

I'm not sure Wikipedia is as "progressive" you think it is.

Wikipedia is really poorly governed. Past admins say that the most common solution to any dispute is the "status quo". They just hope that problems go away. That's not progress.

I don't think I've ever heard this type of complaint before. In my case, and I'd wager a significant chunk of this community, doesn't have too much of a problem putting in an 8 hour day.

There are reactor designs that can't be used to make weapons, and when they fail, passive systems prevent meltdown.
Mm, nah. Running a DNS server, choosing an HTTP server and keeping all the related software up to date is a lot to ask even of a techie. And that's not even getting into dynamic IP issues.
Sounds great! Are you using the official WhatsApp Business API?
Is overclocking (at this level based on this form factor) really worth it? Sure, the speed increases are notable, but I can't see much benefit to overclocking (specifically a pi) unless you are trying to increase game emulator performance or something.

This is all probably moot if you're planning on using the pi for an actual third world type setting as a workstation for schools and such, I suppose.
Once it's down there it might be safe, but the devil is in the details. How do we get it there with 100% reliability? If you think an oil spill is bad, consider the effect of a spent nuclear fuel spill.
Getting offended, emotional, indignant, and angry about any of this was completely uncalled for, and if this is how you go through life, you're going to continue to have these kinds of problems at a rate much higher than the average person has these kinds of problems.
"cherry picked"? There is no doubt that data.table is generally way faster than dplyr, unless you cherry pick a few use cases.

The problem is that dplyr is much slower than data.table and RStudio is promoting tidyverse too much to make the slower choice a default for many users.

The article is 100% correct on this issue.
If it's elitist to want your favorite communities to stay focused and full of friendly, like-minded people, then I'm an elitist.
Yes, we do! In order to do so, every company we onboard need to get access to the WhatsApp Business API (most of them pass via Twilio as it's the fastest way at the moment)
Enormous fonts is a trend in modern web design for some reason. I browse most sites at about 66% zoom. Get used to the Ctrl+- shortcut.
Building new reactors is costly and you need public opinion to agree to that. Unfortunately when someone proposes building new kinds of reactors some asshole backed by "Oil Corp Co." runs ahead screaming "Chernobyl Fukushima!!!" and public opinion is instantly biased negatively to that idea.

Its completely illogical to block Nuclear Power advancement, but goverments are either lobbed or public opinion disagrees after being fed complete horseshit disinformation.

A friend of mine had declared bankruptcy, meaning he wasn't eligible for any kind of credit whatsoever, and his bank let a $10,000,000 withdrawal go through and put his account into overdraft. Naturally, this was on a Friday before a long weekend so he had to wait until Tuesday to get it corrected.

When the bank corrected it the transaction completely disappeared, apart from the screenshots he took there was no trace of it whatsoever.
As if millions of Facebook accounts kept right on going because none of the people running them are in California and Facebook has no incentive to actively police them.
You are 30 years late. In the 80's processed sunflower seed oil, was seen as the healthy (and cheaper of course) alternative to olive oil, and benefited from massive marketing campaigns.

Can't really remember the supposed claims, but involved the usual transfatty acid, saturated / insaturated fat mumbo jumbo.

Fast forward to today, and the sunflower oil is the devil incarnate while olive oil is the hero again.

The same happend with vegetable butter vs animal butter.

I wish i could backup with a source, but I'm really not finding any, and even if I did, most likely would be in Portuguese, so not very useful.
No clue how that works in different countries. Here it's pretty simple: once the money is in the account, you can't do anything. While the transaction isn't complete, you can cancel them obviously.

There's a good reason for that: nobody want's banks to take money out of accounts because they "feel that's the right thing to do".

There's one notable exception: SEPA direct debits getting reversed. Using DD requires a special agreement with your bank, however, and it won't happen that money ends up in your account without you requesting it - or if it does, you will get a phone call from your bank where somebody explains the situation, apologizes a dozen times and asks you to look into the matter and authorize a reversal. Acting on their own would be a criminal matter and likely be of interest to the regulators as well.
Sounds promising!
How is this different from food trucks?

Building based businesses serve the baseline demand, and mobile businesses serve the surging and peaking demand. They are in competition, but neither can capture 100% of the other's market share, because they are not perfect substitutes for each other.
You don't even need a home server, something like netlify or surge.sh makes it dead-simple.
rightly so? the problem you and facebook mom's aren't grasping is that the shit we're doing with fossil fuels is far more destructive and deadly that rotting containers of nuclear waste.
These cars start at around 400 yen for 30 minutes so the love hotel is more expensive, and they typically want to rent for a block of a few hours, but pricing usually works out to around 1000 - 1500 yen ($10 - $15) per hour at a love hotel.

Of course, you get a real bed with a love hotel, so it might be worth the extra if all you want to do is sleep, though the walls aren't super soundproof.
This was the case with my 2015 MacBook a couple of years ago. The “geniuses” were refusing to fix the keyboard free of charge until they realized I was aware of the law suite and their attitude suddenly changed to “we will fix it for free because we have a great customer support”. I garantee there are people who didn’t know better and paid for it. And I highly doubt that “it’s a small percentage of the customers” affected as that page claims.
In fact, the expensive "gaming chairs" that popular kids buy nowadays to flaunt online always looked like car seats to me.
I think a big part of the problem is lock-in! How easy is to migrate all your data from one service/app to another? We actually have alternatives across different products, it's just people are lazy or even worse, it's not possible. Facebook exported my data and then what? With an easy way how to move your account data, the best products would win.
One-Click HTTP(s) Debugging for Ruby
> Somehow, this seems to be a fairly modern problem

With keyboards, yes, but gunk getting stuck in your mouse used to be a big problem, back when mice had balls. :)

Before even that, in PC towers and notebooks with active cooling, they used to be built without dust grates in front of the ventilation fans. The fans themselves used to gunk up!

The real “modern problem” is that you basically can’t clean a MacBook keyboard, since removing any key-cap has a 90% chance of permanently damaging the butterfly key-mech underneath. (I think the main improvement with the successive revisions of the butterfly key-mech is that they don’t snap their pegs off as easily when you remove the key-cap, so you can—in theory—clean them. If you’re a trained repair tech.)
Take the DFMEA angle. Score of three or four for likelihood of a natural disaster screwing the plant over, score of 10 because the result could be a Fukushima-style outcome. Multiply the two to get a risk score, and you're into "we really should do something about this" territory.

Stable-without-coolant tech would have meant Fukushima at least wouldn't have melted down.

Just because it's "really safe" now, doesn't mean you can't or shouldn't make it safer.

And as a bonus: you can tell the press "well actually, this reactor can't melt down!" and 95% of their fear-whipping ability goes away.
The Slow Decay of Japan's Modernist Dreams
They did. https://en.m.wikipedia.org/wiki/Army_Nuclear_Power_Program

One issue was that small-package reactor designs of the 50s and 60s required highly enriched uranium... which doesn't seem like the best idea to leave lying around at (by definition) remote outposts.
Depending on the size of your data, you might not care that dplyr is slower than data.table. If you're better at writing/composing dplyr, you can often make up the speed difference between the two in terms of the savings in time spent writing and reading code. And if your data is that large, there are solutions like dbplyr out there to run dplyr code on various backends and offload the computation outside of R.
A compliant "full featured" cable could very well disable high voltage or high current negotiation. It's impossible for all cables to work in all combos.

What I find interesting is that a swat of new developers thinks that the only options are:

1. free hosting with lock-in platforms (medium, blogger, ...)

2. Clever hacks (github, netlify, cloudflare...)

3. Expensive hosting ($40/m+)

The alternative is to use shared hosting for simple content. Or cheap but excellent services like linode, digitalocean, or vultr. They set you back $5/m or less.

Host your own content, make local backups. If your provider complains, find another host, copy and paste your content and update the dns.
Yeah but it didn't here. Any negative consequence this man experienced was due to his anger and outrage. Calmly handling this situation would have resulted in a completely different outcome.

Yet again, emotion and anger are now somehow the company's fault.
Agree. Async/await and promises get overly complex and riddled with conceptual challenges in anything but the most basic examples. I finally rolled my own async job queue library instead (using .then, granted). A few hundred loc, but conceptually clear, no callback hell, a tiny bit more verbose, but full control over error handling in each callback. Such a relief.
Additionally someone has to finally say "back off" to Oil Industry which is lobbing hard against any Nuclear Power advancements.. I think this is the biggest issue.

(ALMR tests performed in USA already confirmed what you asked for and that was 1984..)
This isn't a small company nor is it a minor drug. This is one of the largest drug companies running a trial on one of the most lucrative drugs in the world.

And secondly, why should ANY drug trial be managed by a PR department? When you ask people to risk their lives to be in a drug trial (in the link above the subject died in the trial), why should it be to improve the PR of a drug for one company. The fact that this exists at all is a major warning sign. The indifference of people to this is frankly amazing to me (its even worse than the disinformation provided by the OP).

My list keeps changing, but I have three main "projects" these days.

- I will complete the final level of a beginner's Sanskrit course this August. This has been an intermittently executed project for me. I can follow uncomplicated spoken and written Sanskrit now, and can mostly understand Sanskrit at the level of Gita or the Indian epics. My long term aim is to be able to read Indian philosophical works in their original.

- I am teaching a few neighborhood kids Mathematics, Physics, and occasionally, Computer Science. This is immense fun!

- I am trying to learn at a deeper level some of the topics that I learned during my undergraduate studies. On this front, right now I am working on understanding operating systems and compilers a bit better.
>Why is it seen as an obvious truth that we should allow every single person onto the Internet, without ever being able to remove them?...

Because it is obvious. Everyone should be able to access the internet.

Now, do the various internet communities have a right to ban people they don't want around? Yes. Absolutely.

However, that's not "gate keeping", it's more accurately called Freedom of Association and the government is implicitly restricted from denying you such freedom via the First. (Provided you are in the US.) And, yes, Freedom of Association is wonderful. That's why we're not subjected to child porn, or nut jobs gunning down little old jewish and black ladies at worship, or 7 year old girls being disemboweled. Etc etc etc. If those people want to share their content, they can, they just need to do it in their own community where the rest of us don't have to see it. Because they are, mercifully for the rest of us, generally banned from our general communities.

I guess I'm just hoping that what you meant was that people should be able to remove others from their community. Not that people should be able to remove others from the internet. (Although a lot of that stuff, I mean, I wouldn't lose any sleep if it became unavailable tomorrow. I'd probably cheer in fact.)

So, the problem of nuclear waste is solved now?
Wind and solar have peaks and valleys of production, requiring some storage to meet demand. Meanwhile, nuclear can be used for carbon sequestration at geoengineering scales when it's not being used by the grid.

Favorite quote from the article: "It's better to have a hole in your team than an asshole."
The problem with the touch bar is that you have to look away from the screen to use it. Physical buttons would allow you to touch type, and I don't think it's a problem to scan the keys a few times when you start using a new app. In that sense they are just as discoverable as keyboard shortcuts. You look them up a few times, and eventually you use them without thinking about it.

> Why is it seen as an obvious truth that we should allow every single person onto the Internet, without ever being able to remove them?

All very well and good until one day society decides you are one of the people that needs to be removed.
>You've plucked an olive from a tree and eaten it? Try it sometime and you'll see...

More often than you'll think. But we usually cut them open, and treat them (is this called "curing"?) in water, salt, and oil.

But the article starts with "Thank goodness we figured out how to press olives into oil, because eating them raw is not a pleasant option" which is simply not true, except if raw here is meant like "exactly as they are on the tree" (as opposed to the oil or paste form that it seems to imply).
Nuclear is not an option as the major energy consumption growth in the next 20-30 years will be in countries/regions where the current nuclear powers will not be willing to trust with nuclear power.
Public opinion won't matter at all until construction itself becomes a reliable process. There are plenty of sites willing to host nuclear, and as our current fleet ages out many sites would welcome replacement reactors to keep the community's economic base going.

However it's abundantly clear that the current tech's time has come and gone. The current designs can't be constructed in the US, as it becomes a Mexican standoff between utility, designer, and contractor, each just waiting to sue the others for what they assume will be inevitable and costly delays and construction/design errors.

The Rankine cycle for converting heat to electricity is just not super exciting any more, and wind/solar/storage may outcompete thermal electricity generation as an entire class of technologies.
Ask HN: Is Tik Tok Breaching Apple’s Privacy Guidelines?
I found out that Tik Tok is uniquely identifying devices and may be breaching Apple’s policies.

1) Install the app

2) Don’t allow notifications or anything else

2) Search 25 terms

3) Tik Tok asks you to log in

-*

1) Uninstall the app

2) Reset Advertising ID

3) Switch IP address with VPN

4) Change timezone, language, region

5) Remove SIM card

6) Restart device

7) Reinstall Tik Tok

8) Tik Tok still knows that it’s you and asks you to log in.

I am sure they are not using the 2 bits from the DeviceCheck API, which Apple allows, but a more privacy invading option.

Anyone here has an idea what it is they are abusing?
