> It can't possibly be economically competitive if it is driving a steam turbine

What do you mean by "economic competition"? Generally speaking with current technology there is no power cheaper than nuclear power. In that sense it is the most competitive power there is.

But not for private investment funds looking to own power generation and secure huge returns in relatively short term. They'd rather see more expensive inferior dirtier climate-changing power generation they can profit from, not government owned nuclear they can't ever compete with. And in that sense no project with long term investments in science, education, infrastructure will ever be competitive for capitalists. So does it really matter then?

Luckily not everyone is fond of capitalists. Ukraine, for example, recently decided to go against certain capitalist run countries pushing it to limit nuclear and finish building new reactors, because other power is not actually economically competitive. If Ukraine can, surely most of the world can do it too.

So a low chances of being fired is better than a zero chance of being hired? If it isn't immediately pertinent to the applicant's ability to do the job, for example if a convicted sex offender were applying for a position as a child caretaker, and the offender has paid their due to society then the employer has no right to ask. Everything but that type of conflict of interest should be treated as personal information. It's the justice system's job to serve justice, not the responsibility of HR.

Yeah that "crowded" cell picture is iconic. I remember my biochemistry teacher showing it several times in undergrad years ago, and really trying to hammer home the density of the cytoplasm.

I am the person who led the effort to get Lisp into space so I am probably as well informed about this as anyone despite being 20 years out of date.

There are some surprising structural similarities between the Lisp and vxWorks environments, particularly in terms of managing updates. vxWorks includes facilities for loading and linking code on the fly, and it also has a kind of REPL, though it is more akin to an interactive GDB session than a Lisp listener. But you can read out memory, load new code, stop and start processes, even do hot patches.

Now, none of this is done casually. You don't just randomly type things at the vxWorks shell and hope for the best. You're dealing with a multi-hundred-million-to-billion-dollar asset and a round-trip light time easily in the tens-of-minutes to hours range. Any interaction is carefully planned, exhaustively tested on the ground, and then carefully vetted through a review process that sometimes resembles a religious ritual or a comically overwrought scene from a bad science fiction show. A proposed course of action is packaged up, approved by a chain of management who don't really know the technical details of what's in it but whose careers depend on it working properly, and then forwarded to an appropriate DSN antenna for uplink. The actual Big Red Button (nowadays its a keyboard) is pushed by someone who has no idea what it is that he or she is sending, their job is just to make sure that what is being sent is the thing that was approved. The entire process is designed so that if something goes wrong, every step that led up to the problem can be reconstructed so that the cause can be found. Fortunately, that is very rarely necessary.

Then everyone sits around and waits nervously while the photons go from A to B and back again.

I work at telemetry system called VendingMetrics. We initially created this with my dad who got over 20 years experience in vending. I must to say, it’s much harder business than everyone thinks.

Trying to adhere to this is a nightmare. The amount of time required to reinvent common words even most ESL speakers know anyway is absurd. But hey, at least you can't say 'murder of crows' right? I know how much that annoys some of you.

HN is in denial about this, but it's a logical conclusion.
Funny, I lean towards the opposite conclusion: That system based entirely on random coincidental collision of matter is more likely to have sprung forth from pure random chance rather than the mind of some individual omniscient being. No matter how all-powerful she might be.
If you work on a very large projects with many released version and need to cherry-pick fixes to back-port, you'd be very, very, VERY glad that each branch got squashed.

Hard agree. The type system is no place for business logic. If you want to get fancy, maybe some database constraints you can change later. Business logic is constraints over the representation... not the representation itself.

Also in generally the principle of "make invalid states unrepresentable” ends with the realization that only Idris can properly do it, which is not pragmatically useful.
How Hatred Came to Dominate American Politics
Yes. If a store’s point of sale system can prevent selling beer in Texas before 12pm on Sunday, it can be programmed to disallow the sale of goods outside of “this is essential” categories.

That would have been the fair way to do it, putting all market participants on the same footing. Courts in Germany and France even ruled exactly that. If some businesses can be open while others are not, the former must only sell the essentials because to do otherwise unjustly enriches those who are deemed “essential with extras.”
As someone who doesn't have unlimited data, the number of services that make it very hard _not_ to use the cloud (including Apple, with their "I know you said put this on your computer, but we really didn't, and we'll just grab it from the cloud when you want to play it on your phone" junk) is extremely inconvenient.

BBC say they have 'confirmed' it's Excel, though still a bit mysterious on how they've done that:
https://www.bbc.co.uk/news/uk-54422505

Particularly, they reckon they were using the older XLS rather than XLSX format with the lower 65000 row limit - although that seems more like a deflection from the fact functionality limits weren't properly handled, tested or designed for.

I've definitely had my fair share of inkjet printers that were essentially worthless. However, my Brother HL-5370DW is excellent. I bought it 10 years ago for $125. This year, for the first time ever, I replaced the toner cartage. The cartage was $70. I'll probably get another 10 years out of the new cartage.
I agree with the conclusion but I'm quite stumped on how to improve that today since aren't even aware of our biases in most interactions. Some definition of Universal Income/Access helps but incentives aren't aligned with the most powerful groups today.

My patchwork strategy nowadays is "Nature is always unfair on the individual level. Leverage your advantages to make life better for those less fortunate." and hope enough people do this to improve the world.
You have got to expand on that last line, it's very interesting. It sounds like something we should be thanking you for.
It is kind of true. Humans are only bipedal thanks to some fairly recent evolutionary hacks, and not all the bugs have been worked out yet. It's totally possible for both sitting and standing to be bad for you.

Another example of relative success: I don't know how it started but I and many others still remember to cut the plastic rings on six-packs before throwing them out to avoid turtles from getting stuck in them if they end up in the ocean.

A lot of people seems to suggest that squashing PR's branches is better because you don't get commits that are broken and it doesn't work good with "git bisect".

But IMO it's not a big deal, you just do "git bisect skip" for these comments and at the end of bisecting session instead of one wrong commit you'll get couple of, for example one commits that builds and two that you skipped and doesn't build. It's very likely that looking only at this 3 commits will help you find the issue because they might be part of much bigger branch which would otherwise be squashed to one huge commit with enormous diff.

I much more prefer to require that PR's branches are always merged without fast forwarding. So there is always merge commit for PR. Then you can actually display list of this commit with "git log --first-parent" and they should always build because build server verifies it.

Unfortunately "--first-parent" doesn't work for "git bisect" now, but it finally will in the next git release! [1]

Unbelievable, they reached the maximum number of columns on a spreadsheet (>16k) which caused the issues.

I'm all for using what works in software, but this was obviously not well planned or designed.
That's an interesting point, but it seems like one among many very good arguments for "right-sized" or "logical" commits, i.e. not 10 similar-shaped bugfixes and also not one-line no-context diffs -- how big should the PR and merge commit be though? Maybe you put the 10 similar-shaped bugfixes together into one PR because they review together easily, but each fix is its own commit, because they all logically stand on their own.

Your use-case is actually the cause of a common rule I've seen at work of requiring a ticket reference in each commit message, which allows looking up the original ticket and associated PRs, along with any commentary & discussion at the time the commit was merged.

On a big code-archeological dig, I often follow a path like run blame -> look at the diff -> pull the ticket reference -> find ticket in issue tracker -> read its description & comments -> find linked PR #'s in the ticket tracker -> open PRs & read diffs and comments -> repeat for linked issues if needed (and then as often as not still end up baffled)

One team actually kept an old redmine VM instance running mostly based on my personal use long after we'd migrated to JIRA, so... I think my approach may be a little unusual! At the least, doing better sized commits would a huge step for every case involving blame.
> "Well, you know, except for all the people not getting the virus due to reduced transmission."

well, you know, except that that's popular (political and media) dogma, not scientific truth. many things can theoretically reduce transmission and it's far from certain that a nominal and arbitrary lockdown (as US states have employed) in as complicated a system as a society actually does so, especially when many mitigations are occurring simultaneously and haphazardly, and none are tested for efficacy in isolation because it'd be unethical to do so.

the null hypothesis there is that lockdowns don't change the outcome appreciably, and that has not been rejected conclusively by any means.
This will be very useful. I'm always watching the road anyway, it would be nice not to have to put the right tension on the wheel the whole time.

Same experience. I like to rotate between 2 chairs, sometimes standing up, sometimes laying down. I still have mild back pain sometimes, but it's way better than what it used to be. I used to barely be able to sleep through it.

If you are suffering from back pain caused by sitting and have trouble sleeping, I used this video [1] to relieve the pain for a while. It helped so much that after 2-3 weeks of doing it every day 2-3 times, I was able to sleep normally again. I also slept on the ground for a while since my mattress was too soft. I now own a very firm mattress.

It's crazy what happens in there. It's as if other lifeforms exist at this cellular level, which wouldn't even care if they form part of a human or a plant, acting as if they have their own life, their own motivation and ability to execute it, their own purpose and will to live by it.

As if what applies to us individuals, with our thoughts and actions, also applies to these subsystems of a cell, in a different form.

What could be their motivation to build humans, to assemble brains that can reflect, eyes that can see, senses built to enable interaction with this world?

Where do these instructions come from?

Search Engine for Free Music Ranked by Usage of Youtubers
Hi guys!

As a Youtube creator, I've always spent great amount of time finding legitimate and relevant music for the videos.

And I've frequently found great Creative Commons music, in Youtube videos of other creators I like.

So I decided to build a simple website where creators can search for Creative Commons music
used by Youtube creators and ranked by usage in Youtube videos.

I think this service may help video creators reduce time spent on finding free and relevant music, by checking what music other great creators have used in their videos.

But before I jump into coding this service, I wanna know If there is any actual need for it.

Please let me know if you're gonna need this service when finding music for the video,
by opting into beta test in the link below.
Thanks!

“Entropy source” is a phrase that has a specific meaning.

https://en.m.wikipedia.org/wiki/Entropy_(computing)

PRNGs, even CSPRNGs, are not an entropy source. They’re an algorithm used to deal with the lack of a high throughput entropy source.

If someone is trying to do an analysis attack on /dev/random (and they aren’t nuts) then we are all in some serious trouble.
