> Is there any progress in design of nuclear fission power plants regarding safety?

> Fukushima...

You mean, hit by the most powerful earthquake recorded in Japan, flooded by a tsunami with 13-14 meter-high waves, evacuated, failed to shutdown, had three core meltdowns and several explosions, and resulted in... 1 death from radiation, 2000 deaths from evacuation and 45 radiation-resulted injuries.

I'd say even this outdated design was very, very, very safe.
Thank you for the link.
I will study that. Since I think it is interesting to see how they earn on essentially harvesting user data and sell adds based on that.
The ads I see are completely useless to me so it is a mystery why companies want to pay for that.
i just have a directory in git and store everything in files

can anyone help explain what i'd use this for?
This type of "treatment" is an utter failure and surrender of the fields of psychology, psychiatry, and neurology.
The way we used to think was - a sex change surgery used to only be performed because we could not fix the mental problem (patient being unhappy with their body). Now the whole script has flipped and we are talking about how a "transwoman has always been a women" and a "transman has always been a man", which is the newest version of "if theory conflicts with the facts, so much the worse for the facts".
Now we actually ponder cutting off people's arms and legs, which is so incredibly bizarre.

Not to mention how this opens a huge pandora's box of "recognising" "transabled" people, "transracial" people (see Oli London, Rachel Dolezal, or Martina Big) as, for the lack of a better word - "healthy".

As a bisexual dude I suspect a lot of that has to do with the stigma around "conversion therapies", but I worry that term suffered from some really heavy "scope" creep.
Hell, we've just ordered an M2 MBA to replace my wife's 2015 13" MBP—which is, for the most part, still running fine; we just want to make sure we're getting her a new one while that's still the case. Don't want to have it suddenly up and die one day.

And I've got her father's 2011 Mac Mini sitting in our TV cabinet running a Plex instance (plus a few other things, like a local internal-only web server). It needs a little fan sitting on top of it to keep it cool enough, but those cost about $10.
As user, I would be happy with a certain amount of beauty and whimsy after it was fully functional. So... Yeah, almost never.
Like I said, other ways. The Nazis built a death factory. The Soviets were fans of starvation and Siberia.
And of course as a further example of their supply chain integration no conversation on it would be complete without mention of Fordlandia [1][2]

The law is being bent all the time. If your business is big enough the gov will not come after you unless there is a political twist(i.e Sackler family) and even then you will not face criminal charges.
> a big part of the cost is the need to satisfy incredibly hostile regulations imposed by politicians who are (a) pandering to public fear (b) heavily influence by the fossil fuel industry

People keep on parroting this, but could you list what these "incredibly hostile regulations" entail?

The only "new" thing I know of is the requirement in certain places (like in Sweden) to have ICSS, Independent Core Cooling System, to prevent a Fukushima situation, plus to prevent a meltdown caused by what happened at Forsmark Nuclear Plant in Sweden 2006[1]

ICSS isn't that expensive BTW. Vattenfall cited the cost of adding ICSS to their 5 reactors to about 3 billion SEK in 2020. That's about 300 million US dollars with today's exchange rate.[2]

No we wouldn't, if the debt caused destruction of the local environment (which it did) there's no way how they could've started making money. Just importing food and other basic goods would starve their resources and give them no room for investment.
To your point, the very first examples don’t really demonstrate much value, even if they are the most basic examples of how it works.

It’s a bit like selling a car by showing all the different things you can hold in the cup holders.
Selective breeding is far more stable and proven than editing.

And honestly doesn't get the credit it deserves for its current position in food security — because you can't patent cooperating with nature.
I have a friend who is a divorced father, and the only two people on his account are himself and his son, who don't live in the same household.

Divorce is fairly common, and coming on top of another recent price hike, they are going to be shedding customers.
We were all fortunate that the social and political resistance to covid vaccines and other public health measures did not result in large-scale loss of life. This was balanced by the rapid development of symptom treatments such as steroids and posture when using ventilators, the appearance of vaccines well-tailored to the initial presentation and a reduction in social interaction caused by a mixture of public health and fear. Finally, the appearance of omicron with its reduction in lethality allowed the hospitals to empty out.

The next wave of vaccines will resemble flu shots in being tailored to current and anticipated variants, so if covid does not mutate into a more lethal form it will shift to an endemic problem like other viruses. The pandemic has shown how well systems can respond to threats, but it’s an open question whether the politization of vaccines and public health will lead to increased problems going forward. If the damned things are encountered by naive hosts, they’ll spread. It’s what viruses do.

And we’ve burned out a portion of the health profession which will have to be replaced at some cost and effort.
I'm not sure I would want to run a company without any gantt charts or deadlines. Management needs to know when a project becomes unmarketable or unsustainable so that project can be killed and resources moved to more viable projects. These decisions depend on variables that engineers can't see, though budgets and timelines are a few of them. Of course engineers can't take it personally when a project is killed either - some projects turn out that way. The best engineers know this. Your comment highlights well the narrow view of the subject article.
Hello Jeremy. Thanks for this great content. I have gone through your entire course and learned a ton from you.

Now moving on from here, do you have any resource recommendation where I can dive deeper into machine learning and deep learning theory? And also any resources to become a much much better programmer?

I am currently working in as an assistant in a research lab. My coding skills are not that great.
I usually keep a project open in Overleaf where I keep jotting down everything that I like. Then on a second pass on my own - I expand or cull the information usually and double checking the information as well.

Here is an example of what I did for Stanford CS 230 notes:
https://github.com/fagan2888/CS230_notes/blob/main/section1/...

I used to write things down. But I am very OCD about the page yellowing or creasing. Also if I made a mistake I usually trash the sheet and rewrite it. For me notes are a way for regurgitating digested information in good details. I do not ever want to look through the book or course, once I have already covered it. So, yes its a bit tedious, but I save time on the long run
The wiki doesn't cite a source that I see. But I looks like that may be recent misinformation

I read it. Im pretty clear on what it does. Im still not feeling the why (or the differentiator from other things that store files and give you URLs).

Remember when Dropbox explained itself by telling you you didnt need to carry around USB sticks in your jean pockets that get washed or lost? I thought that was pretty neat.
I didn’t realize this was the crazy who wrote this article. Wish I hadn’t clicked it.
I used their POD service when an elementary school I had connection to couldn't purchase the reading materials for the classes due to back-order. The program happens to distribute their materials under a creative commons license and make available a PDF of the books. I was able to upload the materials from the publisher and print several hundred copies of multiple books, but eventually Amazon shut us down.

We already had enough for the term, so we didn't pursue it much more but they ended up refunding all of the money that we'd spent buying the books from ourselves in order to, I guess, avoid being complicit in copyright infringement. They didn't really understand the creative commons license.

I'd guess if it's your gig to pirate books you have to play whack-a-mole with getting your books removed, but small orders probably don't get reviewed so the time scale is going to be long.

I know less about measles, but the broader question of how to identify viruses by DNA sequencing is what I'm now doing professionally.

You write: "Also we cannot sequence the DNA/RNA of the virus in order to establish it's identity, when we are testing a soup that has other DNA/RNA in it." That is generally not correct. When you sequence, what you get are subsequences ("reads") of around 200 base pairs. Generally a very large number of them. Then you try to figure out what genetic sequences could have led to you observing those reads, through a process called "assembly". The idea here is that if I have one read that looks like ABCDE and another like BCDEF, it's very likely that these were generated from an original sequence of ABCDEF. If your reads were drawn from a sample that has multiple things in it you will piece each one together separately, and as long as you took enough reads you'll be able to get the genetic sequence for each.

I've been working on wastewater recently, which is a huge mixture of many different things, but we see some extremely common genetic sequences. When you look up these sequences with BLASTN they turn out to be ones people have previously identified as plant viruses from vegetables people commonly eat, such as tomatoes, peppers, and cucumbers. [1] You can download the data and play with it yourself if you want?

Here's an approach that should let you replicate the identification of these sequences and is simple enough that you could code yourself:

1. Download one of the 180 FASTQ files the authors published

2. Extract the nucleotide sequences ("grep '^[ACTG]' fname.fastq")

3. Write a little program that emits all subsequences of length 40. Short enough not to get too many read errors, long enough that mismatches are unlikely.

4. Sort those subsequences. (Unix sort will do it, even though this will exceed the memory available on your machine unless you have a much better machine than I do.)

5. uniq -c

6. sort -nr

7. At this point the data should all fit in memory. Write a program where you make a map from the first 39 characters in a sequence to the last character, and from the last 39 characters to the first. Take the most frequent subsequence in the data and attempt to extend it using those two maps. You should end up with a sequence about 6k long.

8. Enter that sequence into https://blast.ncbi.nlm.nih.gov/Blast.cgi?PROGRAM=blastn&BLAS... It will probably identify it as Tomato brown rugose fruit virus.

I don't know how I would explain this if viruses didn't exist?

There are ancillary benefits to upgrading the grid that retrofitting pipes to pump hydrogen doesn’t bring. Most of America and Europe would do just fine without upgrades, for most of the population. And the jurisdictions touting hydrogen (e.g. Japan) have 70s-era anti-nuke greens in power.

Hydrogen is a smart hedge to pursue. But thank goodness it’s mostly Japanese tax dollars doing it.
> The endless pursuit of revenue to suit shareholders.

I don’t really understand these comments. Do you think Netflix is a charity? “Endless pursuit of revenue” is how they stay in business, employing people and yes, generating profits to shareholders.

Imagine turning this same thinking around at other groups I’d imagine you sympathize with like unionizing workers: “In their endless pursuit of revenue, workers have demanded pay increases”. Like wtf?
There hasn't been a single job where I didn't have to explain Git to someone. Or that Git is not GitHub.

Wherever I was somehow in charge of some authentication / account management (never been my primary responsibility, but "people who know cloud" teams often get that honor anyway) I have always had someone who didn't understand MFA. Either they assumed because MS Authenticator sends them a push, AWS should send them a push or they would have a clock desynced so hard that the most generous TOTP grace windows couldn't save them.

My partner is in a place right now that had to be introduced to python dependency management. Really. No containers or anything like that either. Just alternate runing the script and installing the latest of a package until the import errors disappear.

I really don't mind tutoring, but many of these people also would rather wait 20 minutes for you to respond than 5 minutes on Google. Or even your internal documentation. That's linked in the Slack channel they're asking. It drives me nuts people value their peers time so little.
If you reduce the irrationals to those which can be named you are probably right. I think I said that before.
I mean...he made two points:

1) The Apple Silicon machines are very, very good, in many cases better than their Intel competition.

2) Many tech sites aren't treating them as comparable, and are still treating Windows laptops as the "default", "real" laptops.

Sounds like green throw was addressing point #1, while you're looking at point #2?
You are thinking about market incorrectly. Thinking you have created 1M value for the company is a bit silly. Your work has this value only within context of that company, otherwise just take it away and enjoy the profits.
Google tends to cache pages for a long time, banned users usually leave a long trail (and post on sites where they will not get banned) and deleted posts can be resolved by finding and asking the user in question. And usually people with regrets tend to be very, very loud in scenarios like this.
I know exactly what you're talking about. The first rule of the meeting is "shut up" and the second rule is "keep silent" and "watch your mouth". I don't know why it is so hard to stick to those simple rules when the solution to the engineering problem seems so obvious.

Nonlinear programming has been used in similar construction problems, like maritime platforms. They usually optimize for something like availability. My issue is that there’re seems too be too much variance in the assumptions (like repair time or inspection duration) to make them practical.
- Manager: How long would it take to migrate from A to let's say B?

- Me: What do we want to accomplish from the migration? I'm assuming cost reduction?

- Manager: Yeah, the guys at B are much cheaper.

- Me: Ok, give me until EOD Friday to do some investigation.

- Manager: EOD Thursday would be better, don't need a full roadmap, just enough for an ROI. I'll flip over the CEO's spreadsheet that she's using for the calculation.

For an EV the main design constraints are aerodynamics and weight. If you need to add additional reinforcement to make up for the battery packs that haven't been installed, you're carrying that weight around all the time and taking a range penalty.

So assume your vehicle has 3 packs. You normally run it with just one pack because that's all you need to commute and run errands during the week. When you go visit the relatives in Florida, you install the other two packs to get the additional range. The car needs additional structural elements to meet safety standards when the extra packs aren't installed and they add 5% additional weight. That's weight you're carrying around every day, and that has a range cost.

Could it be worth it to swap out the extra structure elements when you install the extra packs, so at least you aren't taking the range penalty while driving long distance? Yes, but the manufacturer isn't going to want the liability of a customer removing what is a passive safety device, and then forgetting to reinstall it when they go back to city travel using only one pack.

NHTSA will also have input to this. From what I can tell - the applicable FMVSS is this one that deals with EV side impact protection, electrolyte spills, and electric shock.

> Stop estimating.

This! It's more or less impossible to correctly estimate how long it will take to develop anything but the most basic pieces of software, and even then you can't be sure.

I've had so managers who just don't get that there are so many unknown variables in the software development process.

No matter what estimate you give, you cannot win. Estimate short, but it takes longer? Then you are accused of not knowing what you're doing. Estimate long, but come in short? Then you are expected to shorten all future estimates. Estimate right? Nah, that never happens.

Every price of software developed is different and will take a different amount of time to be developed. It is really quite stressful for a dev who is working their ass off to hit difficult targets in an organisation that refuses to be flexible about that sort of stuff.

Especially managers should know that this is not true. Business is a lot about politics and egos, and especially managers are the ones engaging in it.

> One could argue that the Silk Road was created with the purpose of enabling the crime, unlike Amazon

And... that would be exactly why, yes. Intent matters in the law, and the burden on a seller isn't perfection but merely "good faith". Amazon clears that bar, probably[1]. Silk Road very clearly did not. Also, of course, drug and weapons trading gets a vastly higher level of attention from law enforcement than counterfeit hardcopies of tech books. This analogy doesn't really fly. It's like asking why police execute arrest warrants more reliably for murder suspects vs. shoplifters.

[1] There are very reasonable arguments to be had about whether they should be doing more and what internet market-makers' responsibilities are here. I don't expect this HN thread to illuminate them though.
I think we should start thinking in battery cargo trailers. When do you want extra range and battery? When you're going on holiday. What do you want apart from extra range when you're going on holiday? Extra storage space!

So why not just start selling battery cargo trailers which can provide your main car with extended range when needed?

It's also much easier to swap and rent out physically, financially and emotionally than your main car.
That's my bad, I was actually also pretty sure there was a "standard" way to dm on HN. But yeah, I'm probably the one you would find on LK of GH. No Twitter cause I'm a recovering addict :D
Can someone explain to me what all those 7500 employees are doing at twitter? Because I'm totally unimpressed by that.

Whatsapp had 55 employees when it was sold, which sounds about right. But 7.5k for just pushing some data around? GTA was developed by 1000 people, and I mean both programatically and content wise it's way more challenging.

So what are those 7500 people working on?
Depends on the weather for me. Winter in NZ at the mo and I wouldn’t dream of it but a couple of years ago in Hawaii I walked past a cold brew coffee shop and it was exactly what I wanted.
is there such thing as peak "unliveability". where a place becomes a hellish nightmare for all but the 1%.

or does the gap get wider forever and we are heading toward some kind of real dystopia.

i mean what eventually happens to over-saturated markets, be it housing, jobs or whatever else. when demand vs supply reaches peak disequilibrium (cant think of a better word..)

T-Mobile to pay $350 mln in settlement over hacking
I was arrested for linking to a 'terrorist' publication that was FOR SALE ON AMAZON.

And the only reason I linked to it was to point out it was for sale so how could it be illegal? Places like Amazon aren't held to the same standard as regular people and that really needs to change.
