hguant··on My business might have 32 days before it's shut down by NYC [video]
It's frustrating seeing the rhetorical tricks people pull - "these regulations exist only hurt/harm the rich!" - when common observation shows that no, they just prevent people from becoming rich. The poor have nothing, the rich have more layers than God, so the middle class gets the shakedown.

>The small bakeries, the things that bring charm to neighborhoods all over the city.

You're starting to see this in bits and pieces already. New rental space is primarily going to chain restaurants and box stores because the rent is too damn high for anyone not corporate to get started. _The Atlantic_ was talking about the issue of lots going vacant for months at a time because the owners are holding out for insane lease prices...in part because they need to pay insane taxes on the property.

I love New York (in small doses) but it's not tenable as it exists right now.

Because for certain professions income is reliable but not set to a 14 day pay cycle.

Could be that OP is a freelance author and is paid depending on when stories are picked up, or is contracting for multiple employers and has an irregular payment schedule depending on their invoicing.

Not everyone conforms to the same set of employment/fiscal assumptions we (here meaning "educated white collar US tech workers") may have.

hguant··on The James Webb Space Telescope has passed the final mission analysis review
The L2 point is unstable with a period of 23 days? I believe, so the JWT needs a course correct burn to stay positioned correctly (called station keeping).

It does have thrusters - a ring of 16 hydrazine "burning" units that can produce thrust on 3 axis.

The fact that the L2 point is unstable and that thrusters are required puts a lifetime on the telescope - I think NASA plans for a minimum of 5 1/2 years and are hoping to get up to 10. That's entirely reliant on the fuel supply.

The use of thrusters does impact the sensors the telescope uses. NASA et al schedule usable telescope time around burns, and general attitude shifts/correction. The telescope uses a bunch of gyroscopes/flywheels to point itself in the proper direction, during maneuvers like that the sensors aren't operable.

hguant··on Concrete: The material that's 'too vast to imagine'
Part of that is because they have to other wise the building would collapse on its own.

A big issue people don't talk about is that a lot of the concrete China makes is subpar and not up to spec by US or EU standards - they don't use the right (aka more expensive) grade of sand, so the concrete doesn't bind as strongly as it should. The sand used to make concrete has to have rough edges, something about the surface area, which ironically means that desert sands aren't very useful - they've been rounded by wind erosion and rubbing against other sand grains.

hguant··on Costa Rica Has Run on 100% Renewable Electricity for 299 Days
Some available is more available than others

I believe that the issue is that the Earth's crust isn't uniformly thick, and that there are places where one could drill for miles without reaching magma/suitable heat sources, and other places (Costa Rica and Iceland come to mind) where the suitable heat sources are essentially on the surface.

Or, looking at it another way - oil drilling happens all over the globe and "hitting magma" isn't really a risk they're concerned about because it's so deep, that even the industry concerned with drilling too greedily and too deep doesn't intersect with it.

hguant··on FTC and several states sue Frontier Communications regarding internet speeds
This comment violates one of the tenets of HN which keeps it a good place for discussion.

>Please don't post insinuations about astroturfing, shilling, brigading, foreign agents and the like. It degrades discussion and is usually mistaken.

What does your comment add?

hguant··on Discord ends deal talks with Microsoft
Data mining. They've got a huge corpus of information available to them that they haven't monetized yet (as far as I'm aware).

Also, and I don't mean this flippantly - stickers and shit. People want to look different, and selling a sticker or custom emoji pack would bring in money. You see this with Nitro a little, I believe they're experimenting with it

hguant··on The terrifyingly prescient ‘Serial Experiments Lain,’ 20 years later (2018)
I thought this was a good article, but I wonder at the author's background.

>her hardware expands to turn her bedroom into a dim, electrified jejunum

I'd like to think I'm well read, but who the hell pulls "jejunum" out of their duodenum!

hguant··on Benzene detected in hand sanitizers
>The contamination problem in common household products seems like something either the FDA/USDA/EPA should be monitoring

It is - I believe that literally all imports of hand sanitizer from Mexico are subject to an emergency order requiring sampling/testing because of the prevalence of contaminates

hguant··on Tracing Paper (2020)
It's really just incredibly shitty op-sec from The Intercept, which should have known better. This isn't really a novel technique.
hguant··on Tracing Paper (2020)
Type writer, mimeograph, stencils - if you're just doing text or intend for large distribution.

Buy a cheap printer with cash, from a location several hundred kilometers from you.

Go to a non-local Staples, FedEx, Kinkos with a USB stick, pay with cash for copies/printing. Better yet, pay someone else to do it for you.

hguant··on Tracing Paper (2020)
I think that "because the corporations that make printers have a secret agreement with intelligence agencies to track printed papers, going back decades and based ultimately on coercive threats outside the rule of law" is a more cynical truth than "because the companies that make printers want to sell you more ink."
hguant··on Tim Wu Explains Why He Thinks Facebook Should Be Broken Up (2019)
Oh look, another political appointee who didn't do their job, and is now advocating for other people to do the work they were too afraid to do.

Give me a break, it's just another useless "advocate" pimping their book.

hguant··on WordStar: A Writer's Word Processor (1996)
> Back when I was using it, the standard computer keyboard had the "control" key directly to the left of the "A" key (where the "Caps Lock" key is now).

One of the first things I do is rebind caps to control - I've never understood the need for a caps lock key

hguant··on Burned House Horizon
No, scorched earth policy is top down, systematic destruction of the strategic assets in an area to deny their use to an enemy, either to make the logistics of invasion more difficult (Russia during Napolean's winter expedy), to punish the inhabitants (Sherman's March during the US Civil War) or destroy the assets that made invasion worth it (burning oil fields, or Taiwan's bombs under TSMC).

This is just angry folks not want their family homes occupied by a national enemy. If we were seeing scorched earth, there'd be widespread destruction of roads, the power grid, any industrial facilities, and probably chemical posioning of any agricultural land

hguant··on Git's list of banned C functions
Python is great fun, and you can be really productive with it, but for people first coming into programming, a language with an explicit and strict type system is invaluable.

I used to think that everyone should be taught python first, because it lets you focus on the meat of computer science - algorithms, data manipulation, actually _doing_ something - but after helping my girlfriend out with some comp sci 101-104 projects, I really think Go, Java, or Rust should be everyone's first language. It's hard for someone new to the field to understand the nuances that come with python's corner cutting. You can work yourself into some weird corners because of how permissive the language is, where in a (strongly) typed language, the complier just says no.

hguant··on NASA's Space Launch System: is cancellation too good?
RE McDonnelDougalas takeover - I found this to be a pretty well written article going over the basics of what happened. I'm sure there's a book or in depth article floating around somewhere...or maybe not, people tend to be closemouthed about those things.

hguant··on My billion pound company has no HR department
I think the big 'Americanism' comes from the somewhat two faced nature of HR culture in the States - HR are (generally!) the people being super friendly and coming up with "the company is one big family aren't we so happy together" events and whatnot. They're also the people who, in my experience, have mostly bought into the MBA-isms about maximizing value in all things, which includes screwing over said employees as much as possible through legal, yet sketchy methods that make a lot of sense if you're treating employees as resources, not humans.
hguant··on The Viking Invasion of Leicestershire (2012)
>apparently there were female viking warriors

This is a MUCH more controversial idea than pop-history would have you believe. There have been Viking women found buried with weapons and armour; however, there are also men who weren't warriors found buried with arms and armour as well. Scholarship on the matter isn't really sure if the women found buried that way were warriors being honored as such, or rich/wealthy/politically powerful people who were buried in the trappings of a martial society. Also, the extrapolation of "a shockingly small number of women were buried with swords" to "the Vikings had gender equality and badass warrior women in every port" is great Netflix fodder, but not really backed up anywhere else.

>Never mind of course that vikings weren't big on "consent" or that they're darlings of far right groups.

Vikings also literally had a slave based economy; the only thing that got the various Anglo-Saxon kingdoms to unite was "hey, we don't want to be slaves/the main event of excruciatingly brutal human sacrifices."

>compared to those awful Anglo-Saxon Christians

Interestingly enough, almost all the Vikings converted peacefully to Christianity within a decade or two of settling in Britan.

hguant··on 2020 Industrial Capabilities Report to Congress [pdf]
This is DoD truthiness at the core - it only cost 159k to assemble the report, which was probably based on 7-8 multiple studies and analysis that cost a couple of hundred thousand to a million dollars each. This isn't greenfield research, this is a report compiled from a bunch of other reports
hguant··on Why Do We Keep Reading the Great Gatsby?
As you might be able to tell, this comment breaks some of the first guidelines of HN, namely these two

> Be kind. Don't be snarky. Have curious conversation; don't cross-examine. Please don't fulminate. Please don't sneer, including at the rest of the community.

> Comments should get more thoughtful and substantive, not less, as a topic gets more divisive.

In short - I didn't say the things you're implying I do, and your comment comes off as bad faith posturing.

hguant··on Why Do We Keep Reading the Great Gatsby?
>The piece seems to equate capitalism with materialism.

You assume the piece seeks to make an argument, or even a statement, as opposed to making vague references to popular/twitter sentiment.

hguant··on Why Do We Keep Reading the Great Gatsby?
This article is written in what's becoming a new modern 'style' in which the author doesn't say much of anything at all, but makes references, references, and allusions to modern shibboleths and meta-idioms.

This is the high brow version of a 4chan post - its only purpose is to show how clever the author is, and to make the reader feel clever for being in on it.

hguant··on Tell HN: Aaron Swartz died today, 8 years ago
The question of what to call citizens of Utah is a long and thorny one; currently the US Government Printing Office uses "Utahn." [0]

Apparently this was a big 'issue' in the 80's, when the US government usage was "Utahan" or "Utahian," while the local usage was "Utahn." Webster's currently lists "Utahan" as the correct usage, as far as I can tell (their website is trash - searching for "Utahan" and "Utahn" just redirects to the "Utah" entry.

hguant··on SolarWinds hackers were able to access Microsoft source code
It's not just governments - if you give them enough money they'll send you the source, and all the tools required to build it. Device manufacturers in particular need this - you think SeaGate is using the online windows docs when they write SSD drivers?
hguant··on SolarWinds hackers were able to access Microsoft source code
>They just start trying things they think will flummox the software.

This works...until you go against a target that's heard of fuzzing before and has the time and money to do it to their own code.

The really interesting Windows exploits require a combination of "throwing stuff that will flummox the software" and a deep level understanding of structures hidden to the average developer. Look at Yardin Shafir's really wonderful blog post about developing a kernel bug to a PoC - there's a lot of moving parts and security checks in modern windows, and having the source is a HUGE help.

hguant··on Astronomers Find Cosmic 'Superhighways' for Fast Travel Through Solar System
I was under the impression that this was common knowledge among the astrophysicist set, going back, well, according to Wikipedia, to the 1890s when Poincare figured out you could do zero-energy orbit transfers[0].

I suppose the novelty here is that someone identified a subset of 'fast' paths along the Interplanetary Transport Network.

hguant··on U.S. Treasury breached by hackers backed by foreign government – sources
Some of it is based on analysis of the actors motives - if you have 0-day works on fully patched Office 365, that took months/years to work, and throw it at a US government agency, you're clearly not in it for the money, _and_ you have no qualms about blowing your exploit.
hguant··on I Did the Math on My Town’s Cul-de-Sacs. Here's What I Found
Sure, but you need cracks and fissures for water to freeze and thaw into, and without heavy trucks compressing, stressing, and wearing away the road surface, those cracks take much much longer to develop.
