Coincidentally, I recently submitted an article by Thomas E. Dickey on the subject of tar and portability.

* https://news.ycombinator.com/item?id=18969290

The hoo-ha over tar and cpio in the 1980s when the subject of standardization came up, and the whole raison d'être of pax, is largely forgotten nowadays. But the problems that were brought to light back then live on.

The thing to bear in mind is that we already have attempts to improve upon this. The problematic formats in the 1980s were themselves products of the second-system effect, adding on various things to the original tape archive format. We are now, in the second decade of the 21st century, well into umpteenth-system effect.

This brings up a point where this article is very wrong. The pax utility did not appear in 2001. pax was in the POSIX draft back in the early 1990s, and had become widespread enough to be in reference books by 1991. The article conflates the PAX extensions with the pax utility. This, and the incorrect dates, are errors promulgated by Wikipedia, which I challenged back in 2018 at https://en.wikipedia.org/wiki/Talk:Pax_(Unix)#Incomplete_Inf... and which was probably the source of these errors in the article. Always double-check what Wikipedia says on computing topics with a proper reference.

Before being tempted to reinvent the wheel here, I recommend a look at all of the times during the so-called "archiver wars" where this wheel already was reinvented, and learning from them. Of particular note, given this article, is Rahul Dhesi's ZOO file format from 1986. It allowed for multiple generations of a given file, and archive headers marked deleted files with a flag (allowing them to be undeleted), which could be used for "whiteouts". It suffers far less from an extension mess because support for filesystem features from Unix, MS-DOS, and VMS (at least as they were in 1986) was provided in the base data strutures; including 8.3 and long filenames.

But really the basic error here is in using an off-line archive format for an on-line live filesystem mechanism. It's the wrong data structure for the job. Whereas there are right data structures, and have been for years. The history of filesystem formats development includes several cases of addressing the very things mentioned in the article, from deduplication (c.f. ZFS) through generations for deleted files (ODS for Files-11 in VMS, where ZOO got the idea from) to reproducible directory scan orders (c.f. the side-effects of using B-trees in HPFS).
Let’s say some environmental committee is headed by a Representative from New York. An Environmentalist organization from California wants new legislation to improve air quality across the US. Let’s assume no representatives from California are on the committee.

Does this mean it’s not right for the California organization to lobby the New York rep?

I highly doubt every issue a house rep deals with is about their own constituents.
I have had my monitor turn off when I touch my laptop whilst being statically charged. Might well be the issue here too, especially since they mention she wears wool quite often.

However, that was by direct touch, how that would happen when walking by is still a mystery to me :)
Interestingly, the Chinese equivalent of eBay (taobao) does an extremely good job of recommendations for me. So much so that if I search for something, and can't quite find what I'm looking for, often the exact thing I was looking for is a recommendation the next day (or a better version I didn't know exists).

My suspicion is that they have teams of "professional shoppers" seeding the AI algorithms.
You: "I care about my privacy" ... "I use chrome"

Huh?

I feel a lot less concerned about this than who knows what google is doing.

https://www.zdnet.com/article/firefox-tests-cliqz-engine-whi...

"Cliqz does not build browsing profiles for individual users and discards the user's IP address once the data is collected," the firm added."

[...]

"Consequently, aggregation of user's data in the server-side (on Cliqz premises) is not technically feasible, as we have no means to know who is the original owner of the data," Cliqz says. "This is a strong departure from the industry standard of data collection."

And here's Mozillas info about it:
https://www.mozilla.org/en-US/privacy/archive/firefox-cliqz/...

Why should I be concerned? Given this information, why would I choose Chrome over Firefox for my privacy?

React-Wasm – Declarative WebAssembly Instantiation for React
Hiring manager says org chart is flat, but LinkedIn says otherwise. What to do?
Two weeks ago I applied for a Senior Software Engineer role at a great company, whom I've just received a verbal offer from. They've met my compensation requirements and passed my culture test.

What concerns me is that the hiring manager asked if it'd be a dealbreaker for me to join the team as a Software Engineer rather than a Senior Software Engineer. The hiring manager explained rather briefly that the company is a rather flat org that doesn't really hire seniors.

But upon searching LinkedIn, I found 3 Senior Software Engineers working at this company (the engineering team is only 9 people).

I don't mind ditching my senior title (I've been a senior/lead at my last 3 workplaces). I just want to know the truth about why they didn't offer that title to me when there are clearly employees at the company with it.

How do I bring up my concern to the hiring manager?
You're also not mentioning the other half of the equation: calorie input. If someone eats the same amount of food, and walks more, then they're burning more than before when they were just sitting on the couch. Of course what often happens that the body starts wanting more energy for the new activity level, so many people end up eating more--no net change.

It should also be noted that there's more to exercise than just weight loss.

well most probably twitter might not be able to cope up with future attacks or the cost to mitigate them.
Ontologies are problematic because they are almost invariably hierarchical and binary.

If your ontology is probabilistic and multi-dimensional, it's much more likely to represent truth.

I actually think ontologies are a trap for smart people. For people who like to systematize, they have an allure. Ontologies give you the illusion of putting the chaotic world into order. Even phrases like "true facts" - in reality, facts are hard to come by and change over time, and the closer you look at them the more woolly they get - predicates are far too abstract and simplistic, and when you dig in, the fractal messiness overwhelms.
Companies like Twitter would get a significant discount from any provider, though I imagine AWS as market leader would have less incentive than GCP to go quite as deep.

Disclosure: I worked for GCP until early 2015, but I haven't worked for Google since then, have no inside info on this deal and am not relying on anything from my time at Google for this comment.

Ask HN: Open Courseware solution as part of a sideproject?
A Laravel-based B2B side project I'm working on requires the administrative user to be able to invite people to take a web-based training course. This should happen by sending an email containing a unique URL so the user can start the course immediately without needing to log in.

Laravel has some quiz packages that are too simple (lacking functionality to include videos, explanation etc.) and most courseware products are built for schools and too bulky. I'm considering taking edX and strip it off unneeded functionality. I was wondering if people have done something similar before and if there are better options?
Construct 3 browser game engine open access for Global Game Jam
For this years Global Game Jam, we're doing an open access period for Construct 3:
https://editor.construct.net/

Construct 3 runs in the browser, we've written all the JS code ourselves and it's packed full of interesting tech we think HN would be interested in! Our latest beta introduced Z elevation which can do cool effects such as:
https://twitter.com/LastMoonGame/status/1086920331443474433

To help give a little back, we're also donating $10 to the charity Special Effect (https://www.specialeffect.org.uk/).

Making a full game engine run in the browser was a huge challenge, but we think we've nailed it! If you're looking for a game engine to use this GGJ we'd love you to consider Construct 3. Happy to answer any questions if anyone has any!

> no increase in standard of living or health benefit

Many people use body modification to feel ownership and control over their bodies, or to essentially make a part of their identity physical. This no doubt has mental health benefits - my own piercings help me in feeling control over myself in a society that seeks to take that away from me.
Not just that, also the amount of sugar in those portions is astounding. Luckily, when I visited the USA for 3 weeks, I didn't have time to get accustomed to that, and I actually didn't enjoy to eat that kind of food. Unluckily, now that I've been living in the UK for 6 months - where the amount of sugar is less than in the UK, but much higher than in Italy where I used to live - I'm starting to notice it less and less.
The AP news ticker has its own bias and narrative, as does Reuters. There is no truth in any text, only narrative. So long as you are reading trying to find truth in a single text you will fall into error.

Feud Over Financing the Aswan High Dam
It could coincide with one of Employee 2's habits or routines before they leave their desk. For example, I used to have a cheap fan on my desk and whenever I changed the speed or turned it off, it caused all of the Dell monitors nearby to go blank for a few seconds before turning back on and readjusting to the resolution of my laptop. I usually turned my fan off whenever I expected to be away from my desk for more than a few minutes.

> On the contrary, I prefer my languages lightweight, and capable of allowing arrays (and strings, dictionaries, etc) to be implemented by libraries.

I agree with this philosophy! But that is certainly not at all the case with python, where fancy strings and even fancier dictionaries are readily available at the language level, instead of being implemented as separate libraries that you have to import.

If Python did not support strings nor dictionaries as basic data types, you might have a point. But it does, and it chooses to ignore multidimensional arrays and their basic operations. This is weird, and even a bit offensive when all you need to do is dealing with such arrays of numbers. You always feel like an "outsider", unlike when you program in octave or julia, for example.
Obesity rates in both France and the US are rising at similar, alarming rates. In the mid-90s the US surpassed 24% obesity rates, and at that time France was at less than 10%.

This is crazy. What are we doing? Nobody chooses to be fat, except maybe sumo wrestlers and a few other strange outliers.
I expected to read a solution, not just the symptoms- but other than the theory that the monitor is connected to a power cable that runs under the floor, and the employee who triggers the screen to shut off is heavier than the others and stepping on the cable, there isn't anything relevant posted there. I'm currently searching for a solution to a clients' random monitor shutoff issue so I was hoping for some insight!

It did, however, give me a greater appreciation for the quality of comments on HN compared to Reddit.
Mendeley was originally a startup. Precisely why people even started embracing it (though I didn't, something always felt fishy for me) and then they got acquired by Elseiver.

I have nothing but good things to say about about Papers for Mac though.
I didn't mean this story specifically when I said "outright false" - obviously this one's still up in the air. But they reported on the Covington Catholic High School debacle, which has since been (as I understand it) shown to be false. That's two high-impact stories - one false and one in contention, in a couple of days.
And how is the build env recorded for timestamps and env variables? Is all of this standardized?

Wow, congratulations to the Julia team!
> My understanding is that chaotic systems are still deterministic,

Classical chaotic systems are indeed deterministic in principle, and only effectively unpredictable due to finite measurement precision. But the world isn't classical, it's quantum, and quantum systems are fundamentally indeterministic.

(You can make a philosophical move where you say the wavefunction is deterministic even if the results of our measurements are indeterministic, and the wavefunction is the "real" thing, but that's orthogonal to the point I'm making. All I'm saying is that the meteor's path, on long enough timescales, is random in the same sense as radioactive decay.)

> "Irreducible quantum uncertainty" is something else that has nothing to do with Lyapunov time.

I think I'm going to have to pull rank on you and just say you're wrong on this one :) There's a whole field of quantum chaos that explores the relationship between these things in depth. Here's one of my favorite papers:

https://arxiv.org/abs/gr-qc/9402006

> I also see Lyapunov died in 1918,[1] while the uncertainty principle was introduced in 1927.[2]

I'm discussing the implications of chaotic dynamics for quantum systems, and scientists generally do not live to see the implication of all their ideas. Maxwell realized that light is just vibrations in the electromagnetic field, and he died in 1879, yet we still start by writing down Maxwell's equations when learning how light operates under the laws of quantum electrodynamics.
Ultima is an RPG series (probably the founder of the CRPG genre). It has 9 single-player games as well as Ultima Online.
Personal experience: I made the switch soon after starting my PhD and never looked back. Also, their Connector plugin for Firefox is a life saver. 90% of the time I only have to lookup the title of a paper on DBLP, then export it as BibTeX and pronto, the reference is now in my library with most of the relevant metadata. Much better than Mendeley's quite opinionated plugin (which also won't work unless you log into Elsevier's servers)
Both clouds charge significantly for egress. Were you sending a lot of network traffic to SaaS vendors that were hosted in AWS but not GCP? That would make your choice pretty natural, assuming you wanted to stick with those vendors.
Yes, there are some low hanging fruits. My country (USA) is the worst offender. But if you do the math, we can't afford to consume the same amounts we do now with fully sustainable tech. Not yet. I didn't mean to imply we have to swing cats into creeks and dig in the mud with sticks. But we will have to do things like pay more for meat, imported goods, electricity, and gasoline. We still can have them, but they would be more expensive, sometimes a lot more (such as airline travel). There's no way around this. We could have the rich subsidize the cost of these things for the poorer, but regardless, emissions-producing goods will need to be consumed less for emissions to decrease. How could it be any other way?

Emissions from the creation a given good/service can be reduced in 2 ways:

1. Reducing the consumption of said good.

2. Making the good sustainable.

Case 1 means either rationing a good or raising its price. Case 2 means raising the cost of production. In both cases, it costs more to consume the same amount.
I was working on my taxes last weekend and I hit a bunch of them. ADP, the 401K and FSA provider sites, Aetna, and a 529 saving plan site are all ones I can think of off the top of my head.
This is literally the worst thing you can do. Even a tenured professor doesn't seem to stay in the same institution for their lifetime nowadays so why would you go to a service that even you personally cannot pay for yourself (reasonably)?
Thought experiment: imagine installing Windows 10 on your newly acquired Mac Book Pro. Now you have spent a minimum of 1500€ for barely functional hardware and half-asses software designed for tablets with build-in ads. The state of available pro laptop is saddening these days.
Interesting, so lobbying efforts from within the company appear to be unaccounted for. I'd also venture that ancillary costs (especially legal services) are unaccounted for.

That really diminishes the meaning of the quoted $20m. For all we know, Google and Facebook could be spending ten times as much on staff lobbyists and lawyers.
From the interview with the award recipients:

“A programming language cannot be derived from first principles alone. Language design is applied psychology—the computer program is the ultimate human-computer interface. Sometimes you have to try a design out and see how people interact with it and iterate based on that real-world feedback.”

No org is truly flat, but conversely I've been at places that only or predominantly hire "seniors".

Really the only thing the title matters for in a "flat" org is getting you into the next job. You have to decide for yourself whether you're going to have problems with that on your CV, based on what else you've done and how prestigious the job is.

Otherwise you just have to ask; try arguing that if it's a flat org then a "senior" title doesn't cost them anything.
