Different implementations of Nix might have the same issue in some places. In this case, whether the language is fully defined is orthogonal to whether its behavior is deterministic; here, a particular implementation will continue to be as such.

As far as I know, Nix doesn't have a formal specification; it is defined by its reference implementation.
It sucks that you couldn’t recoup any compensation, but I’m not surprised at all. You don’t have a relationship with the other person’s insurance. You have a relationship with your insurance. Your insurance covers you, and your insurance may try to collect from the other driver’s insurance company.

Also, this is why auto insurance offers uninsured & underinsured riders (add ons). There’s no guarantee that some jackass who hits your car will have enough insurance or any insurance at all.

The issue I have here is the problem that they are not strait or white? Or it is a cultural problem where their behavior and actions are not the cultural norm?

basically I dont believe it is the fact the person is non-white, or non-strait that is the issue, the issue is the actions, behaviors, attitude, and likely politics of the person that ends up being the problem, not their immutable characteristics.
Where in Eastern Europe? Taxes there and cost of living are generally much lower than Western. At least, I quite like it.
Is not that INTP thing Myers-Briggs that is mentioned in the article?
Agreed. Simple checks like these are trivial:

A call to function "Foo"
Must always have an argument matching the regexp "/blah/".
Otherwise raise an error.

And they're so lightweight you can add them to any CI/CD/automation steps in your repository. Once you get a few things like that, or validating naming-standards, you can roll them up into a simple "linter".
It is fascinating that they solve robustly 50 times per second a control problem and handle gracefully numerical issues. Granted they have dedicated hardware to do so that fast, but it never stops to amaze me.
Great to see DDG growing steadily. I've been using it on all of my devices for going on four years and it's proven to be an enjoyable experience. Their extensive collection for !Bangs, in particular, has proven beyond useful for quick and easy searches in a single location.
Thought they were going to talk about psychoanalysis.
The largest WildDuck setup has been running for 4 years, and its MongoDB cluster stores about 100TB of data, hundreds of millions of emails for 100k+ users. There are some quirks but so far the setup has been quite reliable. It is probably far easier to upgrade a single MongoDB instance in a cluster than to upgrade a "normal" email server with a large maildir folder structure.
I do embedded development and I use Glibc on all of our products. It's as simple as checking the box in Buildroot, so why not? The version of Glibc I am using has special accelerated memcpy and string functions for my CPU (e6500 PPC, Altivec).
>Apple is waging a talent war with companies in Silicon Valley and beyond, with Meta emerging as a particular threat. Meta has hired about 100 engineers from Apple in the last few months, but it hasn’t been a one-way street: Apple also has lured away key Meta employees.

>The two companies are likely to become fierce rivals in augmented- and virtual-reality headsets and smartwatches, with both planning major hardware releases over the next two years.

Who would buy a watch from Facebook? Isn't that bound to be a privacy nightmare?
Perhaps Facebook is relying on people not recognizing the Meta brand name that will be printed on its future devices but I am not too confident about that people will be flocking to buy it.
SF to Orlando here. The tax benefit was huge, CA taxes were around %9. That alone covered a mortgage in Orlando - which has no state income tax. While working remote in Orlando I fixed up our house every weekend by watching youtube videos. Eventually I sold this house for a massive profit within 2 years and upgraded to a much larger home. Looking back paying SF rent prices I could kick myself for not leaving quicker. I looked through all the spending in SF - and realized rent control is the only way to make any money in SF. You need to lock in a cheap rent and sit.
Sure, I'm pasting it below. Since I might sometimes want bold-face, I am also colouring it red, which my journals will not permit. (I am not sure how this will format in hackernews, but the main thing is that you uncomment either of the two `newcommand` lines.) If you want to do other things, you might want to use the `\if` method, so that altering just one line will let you alter a bunch of properties at once.

I'm not sure which this article claims to be the bluff: the author or the DiSC assessment? ... It seems to be attacking both.
Mind sharing the name of this Shringla?
Yup, this. I don't understand either. The transaction (amount / gas fee / max gas / to / from / code if any / nonce) is hashed using Keccak, then that hash is signed. The transaction also contains the data in the clear. Nodes take the data in the clear, recompute the Keccak hash, recover the signing address from the keccak hash + r,s,v then, if there are enough funds on that signing address, the transaction goes on.

How could reusing a nonce once lead to a full compromise?

Or is it only if the nonce is reused, but for the exact same transaction, with all the parameters identical, then signed using the same private key but some other random point?
Batteries also have started to make sense due to recent plunges in their cost. Hawaii / California are doing this.

Hydrogen makes negative sense due to insane storage costs but gas/oil companies still like promoting the idea, probably due to their sunk costs in natgas investments.

Much less storage is required than most people think. Battery storage is entirely economically feasible. Cheaper ones like hydro are even better.

Norway & Britain just completed a new interconnector so that Norway can use Britain's cheap wind power and Britain can use Norway's cheap hydro storage.

I think there is a major difference between Steve-Jobs era and Tim Cook era. Lots of people's past experience may have been Steve Jobs or slightly past Steve Jobs era from 11 - 14, where most of the things stayed the same.

I tend to think 2015 was a turning point. And everything after is Tim Cook era. Also depends on org as well, for example vast majority of bad comments could be traced back to Apple IS&T. And you dont even need insider story to tell, simply judge them by IS&T's output on iCloud and any services.
I've implemented the 1588 protocol a couple of times, and I have less optimism.

This "era" thing seems like the exact type of thing that someone would ignore when implementing the protocol, or if it is supported, probably doesn't get tested much. It's like leap seconds. Yeah, the leap second info is conveyed in PTP, but most of the implementations I've seen simply ignore it and just jam the clock when the time jumps.
Fuck! I didn't know about play-to-earn.

At this point, I'm starting to think our species had a good run, but it's time to replace it with a more evolved one. And just like dinosaurs were wiped by a global catastrofe and left room for mamels, it's time for homo sapiens to leave room for a new species.

The silver lining? We don't really need to do anything, just watch for our self-made catastrophie to unfold.

Popcorn anyone?
In some fields, the boss mandates to have their name on every paper published in their organization, even if they are not involved in the research, or even if they do no research at all.

For example it looks the (in)famous Didier Raoult was cited as author (on average) in publications at least every three days in the last 10 years:

https://pubmed.ncbi.nlm.nih.gov/?term=Raoult+Didier+marseill...
With their privacy focus, does that mean they don't track and keep a list of database queries being made? I'm quite curious to what people may be searching at DDG vs. say Google - it certainly feels like there'd be important societal insights possible with that data. If they do compile it, do they publish this data anywhere?
I've lost the thought around this part:

> For example, consider a person who says, “now I understand why I have such negative thoughts, can’t get to sleep, and have difficulty getting going…I’ve got depression.” This person might believe that the explanation of her symptoms is depression, but in fact, the diagnosis of depression is just a categorisation of exactly these symptoms.

The diagnosis of depression usually revolves around changes in body chemistry and the functioning of the brain. It is an issue as real as diabetes is. To explain my point further, consider the following:

> For example, consider a person who says, “now I understand why I have such frequent urination, increased thirst and increased appetite. I’ve got diabetes.” This person might believe that the explanation of her symptoms is diabetes, but in fact, the diagnosis of diabetes is just a categorisation of exactly these symptoms. There is no diabetes Gremlin, either.

All this not to say that the accusations of fraud are either based or baseless.

EDIT: I know we can't test (blood etc.) for depression — yet. There's still a question of whether "it's all in your head" or "your biology is a bit off". See also [0].

I'm in the SFBA, but grew up in central KY and eastern TN. While I'm very interested in moving out, my wife isn't ready yet. Personally I find California to be oppressively over-regulated (zoning and planning are horrible, but the limits on what I can do and buy are also heavy-handed), unreasonably expensive (primarily housing, taxes, fees, and energy), and the people too judgmental of others and their differences (trendy-issue virtue-signaling is a competitive sport). It isn't a healthy or cost-effective place to raise kids.

The only things going for the area used to be nice weather and tech jobs. But now that summer and early fall are filled with smoke and the jobs can be worked from anywhere, why stay? My wife agreed to move out as soon as we had a child, so I'm pretty excited about having the opportunity for an escape.
In general, for me at least i find the best way to learn about something is to work in the 'internals'. For instance when react came i couldn't wrap my head around it so i started my own js framework, and it ended up almost exactly like react (then i dumped it as it ended up just being a learning exercise)
I think there's something interesting in Myers-Briggs. It's crude, flawed and inaccurate in many ways but your sniggering rubbed me up the wrong way.
I once worked at a shop that developed slightly more modern GUI clients for their mainframe systems, we got TN3270 emulators. fun!
There's a reason intellectual gratification is the bar and the goal for topicality, not emotional catharsis or pop-cultural notoriety. If simply being popular with American males became the standard, this place would degenerate into Reddit.

> To fix this you need a persistent low water mark on the time

Yep, this is what many GPS receivers do to deal with the 20 year issue. They burn their manufacturing date, so they know which "cycle" they're in.
To go to the opposite direction from the low tech starting point: You could have both a micro-chp setup to genetate both heat and electricity from the fuel, leaving the option to use the electricity on a heat pump or other household demands.
I really wasn't expecting anyone to read all of it, I was afraid people will either find it too trivial or too complex based on skill level. So that's great to hear.
The nonce used for ECDSA signatures is not the same as the nonce used for Ethereum signature. The term "nonce" is a general term that is used in any number of systems to mean a value which should only be used once, and might apply to any number of layers or protocols in a given system.

There are various techniques people use for them: a careful counter, a precise timestamp, a hash of the rest of the data, or a random number. Often you can choose as the user... as long as you don't use the same value twice; alternatively, your choice of nonce might be verified by your counter-party (as with Ethereum's account nonces).

The consequences of using the same value twice will also differ: your request might be rejected/ignored, you might be penalized or cause an error, it might expose your identity to a system where you were otherwise anonymous, or it might allow someone to calculate your private key. The high-level idea is what matters, not the specifics.
I started on a FF Creator Pro clone, then added an Ender 3, then built (and heavily modified) a SecKit Tank.

I recommend people start with a simple off-the-shelf printer. (Ender 3 on the cheap end, Prusa on the expensive end).

Automatic bed leveling is a huge quality of life improvement IMO (Prusa comes with, can be added to others). Other factors are size, speed, and filament range (temperature range, part cooling, extruder and drive, dual extruders, enclosure, enclosure heating).

I’m a tinkerer and don’t mind modifying printers. If I’m printing a random ABS part, it’s still going on my first printer. If printing a large part, it can only go on the SecKit. For a random PLA part, it’s going on one of the Enders. If I need two filaments (at once), it can only go on the FF, etc.

If you don’t own a printer now, start with an Ender 3 and a PEI spring steel sheet or a Prusa. If you start with the Ender, I’d also add auto bed leveling early on.

If your usage indicates the need for a more expensive printer, it will reveal itself and by the time it does, you can keep the cheaper printer, sell it for 50%, or cannibalize it for parts.
Google search product as become progressively worse each year.

DDG is not much better, I dont believe there is any good search product out there right now, however for technical topics I often find DDG easier to find things from actual manual pages, or Knowledge bases where Google I just get lost of Marketing Blogs trying to sell me something

The ironically exception to this is some time Microsoft own documentation is harder to find on DDG (which is backed by bing) than on google... I think that largly has to do with MS terrible choice to remove technet, and break 50% of their links on the internet.
It is not ‘technology gone wrong’ it is ‘the system worked’.
I have all my devices default to DDG except one, and honestly for 98% of searches I don't notice (it's been over a year now).

I do still pull out a !g for weird software related searches that DDG seems to interpret wrong or only return a few foreign language results for.
I could bet algorithm has changed a lot since 2013
True, although still worth reading albeit with that in mind.

Please be more constructive in your criticism.

As an example

> WHAT ??? Nobody who knows the "Scientific Method" and has trained as an "Engineer" will ever agree with you. You are taking "one facet" of a specific Engineering Discipline and generalizing it to the whole Domain of "Engineering". This is a fundamental logical fallacy.

How is it a fundamental logical fallacy? Why are we making broad statements for the whole industry?
My other favorite search engine next to DDG is https://search.brave.com/.

I try to use these two and only fall back to google in rare occasions these days.

Could you post references regarding the issues you have raised, as it contradicts other claims below that sees hydrogen storage as unavoidable.
Flooding the original chain with fakes doesn't make them look real: they are different tokens. It isn't like computers are squinting at the hashes and timestamps and public keys and getting confused as to their identity.
I know the title of the book as it was for a brief period on the receiving end of some ridicule (rather than praise), though I hadn't heard about its "colorized" idea until I read this article. As I remember it the book made at most a bit of "noise" in media, more so than being a wave of revelation, and my gut feeling as a Swede is that most people bought the book out of the sensationalist and entertaining promise. I don't think I've ever come across a person here in Sweden expressing or applying the presented ideology in any way.
I may be wrong but it may be based on babashka [1] which is a subset of the clojure runtime natively compiled, and has std IO files available built-in.

I read some of this article. I have never heard about the color system in question. If it’s really a fraudulent system, it should be easy to say “The system claims thing X, here is evidence X is false.” Instead, this article is filled with anecdotes and what seems like random conjecture on what personality “really” is. This is not a convincing argument.
Data Storage in Serverless Applications

Nginx 1.21.5 Released: Changelog
The "lead or be led" trope is apt, and certainly became the paradigm of my doctoral years. I might, however, amend this slightly. There's another idea of going rogue too soon or too late (https://matt.might.net/articles/ways-to-fail-a-phd/).

Students, new employees, and other inexperienced folks need to be led initially, and then rapidly, transition into a self-directed paradigm. Success emerges if and only if the advisor and student recognize the need for this transition at a similar moment. The alternative is either the student who runs down rabbit holes repeatedly despite being guided elsewhere (those students tend to at least get SOMETHING done and while they take forever to graduate, do find some interesting results along the way) or the student who after a couple years is still just reading papers and waiting to be told what to do (these students often fail outright as advisors get fed up with the hand-holding).
It was the best selling pocket book in Sweden in 2017 and 2018. 800 000 copies have been sold in Swedish. It was pretty difficult to miss.
There are some parts of the book that are perennial, namely discussion of the UK's geography, which is relevant to energy storage.
Well, they do have an impact. Not being a hazard is a different thing.

These things in public ways do require people to pay attention to them, grant them rights of way, etc...

A few of them works one way. Oh look, it's cute!

A lot of them? Very different story.

There should be a discussion, and Toronto has forced that discussion apparently.
Neat.

If I understand correctly, their work makes diagrams and code isomorphic. Meaning roundtripping between diagrams and code can be done with no loss, no impedance mismatch.

Meaning my long-time dream of a two-way structure editor is now feasible. Edit the diagram, the code updates. Edit the code, the diagram updates. Back and forth.

As you know, the Achilles Heel of CASE tools (and visual programming) has been the inability to roundtrip.

Do I understand correctly?

My science-fu is weak. I've been struggling to wrap my head around grammars and whatnot my entire career. Please forgive.
I found this also interesting. I can see how it simplifies the mathematics to use a fixed time interval.

Can anyone experienced comment if 10Hz is very different or the same as vehicle control systems such as a modern car?

Also, are these systems fixed or floating point? Fixed time intervals would help keep numerical instability of floats in check (however I'd really hope this is more formally understood for such a safety-critical system.)
Large wind turbines are interesting, because due to the lower friction from the ground winds are stronger up there so the capacity factor is appropriately higher.

They also scale in power with the swept area, so it pays to make them even larger.

IIRC the current state of the art is 14MW with a 60% capacity factor and that is not the manufacturers' last word.

Exiting times ahead for wind power because while it's still intermittent, it gets built so much faster than nuclear.
The big sell was holding heat made during the night during off-peak hours to be spread during the day when rates go up.
I moved to a cheaper place, (change city and state) got a home with garage and a pool. The mortgage is less than my previous rent and more than twice space wise. I found a place very quiet but very close to a big city and airport (10 min).

There are pros/cons because life is always full of trade offs, but was the right decision for me and my family.

Before COVID I used to commute 30 min each way morning/afternoon. I was close to a city 30 min. The airport was like 1 hr. Living in small apartment no to much space for living just sleeping.

I recommend to evaluate your current situation and chose what is best for you and family. Also make a list of pros/cons of possible places to relocate/move if you thing is moving out is a good option.
Re-reading the article it's not when the nonce is reused, but when in the (r,s) of the signature the 'r' is reused. To end up with the same 'r' twice you must reuse the nonce but, I think, not only that. If you reuse the nonce but change any other parameter (for example putting slightly higher gas fee), then I'm pretty sure the 'r' changes (I'll go test that now out of curiosity).
Totally weird, also if the article were true, it would suggest going out, trying to think positively were effective treatments of depression (which they are at most for light cases)
