skylanh··on Does the Tank Have a Future?
This is sort of my reference point from a salient and personal perspective on why government's have departments of defense.

skylanh··on I want an iPhone Mini-sized Android phone
> In a 2014 case out of a Virginia state court that seems to have set off the current debate, police obtained a search warrant to search a suspect’s home and to seize various items, including his smartphone that had TouchID enabled.

> The judge in that case drew a bright line: Under the Fifth Amendment, police could not force the suspect to communicate his passcode, but they could force him to use his fingerprint to unlock the device. The reason?

> Providing a fingerprint was “non-testimonial,” because it did not require the suspect to produce anything from his own mind. On the other hand, to give up your personal passcode is classically testimonial, since it comes from your head.

skylanh··on Uber concedes deception, prepares for $26M ACCC spanking
Taxis in my areas are a municipally regulated monopoly on fare-for-(uncontracted)-hire services.

There are a lot of reasons why they devolved to the level of service that we associated with them:

1) lack of competition

2) internally there is no reward for excellent service

3) as a regulated industry, the internal players will try to stretch the margins to make it more profitable to address either a) greed, b) actual operational needs--cash only, "my terminal is offline", fake terminals, tourist routes

Most of this points to failings with how the models are implemented:

- diffuse reward system that doesn't account for fare-taker's feedback

- slow, high-effort negotiation modification to a) fares, b) license / medallion holder needs, c) driver's needs, d) fare-taker's needs and feedback

Consider the differences between Uber and Taxi:

1) feedback is tied directly to driver and passengers

2) feedback is instant

3) Uber dictates pricing and can do so based on a regional, time, legal games, and overall load basis on a low latency regional authority's direction (one person could make that decision based on their local knowledge of upcoming concerts and NFL games, or the status of their application for licensing with the city)

4) individual drivers are now the liability / cost holding party

One thing that I think should be in your mind is "who is losing in either model and why?"

Potable water with nutrients, bioflavinoids, and antibiotic content is definitely an excusable reason.
skylanh··on Apple unveils the best photos from the Shot on iPhone Macro Challenge
Wait until you start looking at transmission values...

f-stop doesn't mean much other than the maximum that the aperture for that lens can open.

It doesn't indicate lens or element quality, or aberrations. There's a reason that pixel peeping, gear games, and reviewers are so prevalent in high end photography.

As a simple extension to this, most of my lenses work better a few stops before maximum f-stop.

So, yes, but no.

skylanh··on San Francisco cops pull over a Cruise driverless car for no lights on
Boeing's issues were written on the wall about 2 decades ago when it moved it's hierarchy from an engineer-centric one to a Chicago accountant-centric one. That alone wouldn't have been an issue, but they had an immediate brain drain as half their HQ staff didn't follow the relocation.

Imagine a thousand employees, half your HQ staff, that leave. There are several possible reasons:

- they're older -> more corporate knowledge and knew the "magic recipes"

- skill based mobility -> they're so good they can go anywhere, and Chicago isn't Seattle

- etc

https://hbr.org/2001/10/inside-boeings-big-move

This was widely thought on ... what was I browsing back then? Reddit? as a fore-warner of bad stuff to come

The fore-warning came to fruition when the issues at various Boeing plants started developing over the next ten years (insider videos talking with an employee about being on drugs during crucial assembly work and shift mates being similarly high, "get it through your station" attitudes) and the Dreamliner issues that were hand-waved away (no training, 1-hour tablet self directed training, certification delays, and eventually crashes).

This is what it took to reverse 2008's recession. Every time I read this single page document I get a little shiver.

skylanh··on How much did VHS tapes cost in the 80s?
TV shows were scheduled for your local stations and there may be an alternate channel that would have an echo or rebroadcast schedule.

If you wanted to watch "your show" you had to either have someone record it, or record it yourself. There were even VCRs that could be programmed to start recording at a certain point for a specific duration.

In all of humanity's many combinations of people, situations, and outcomes, yes, this has happened hundreds of thousands of times.

It's literally a meme that "oh! no, don't watch that one--that has our sex tape in the middle".

skylanh··on Disaster planning for regular folks (2015)
(Speaking totally out of turn and without any sort of knowledge of the situation)

The rapid response of the Yakuza may simply be opportunistic and predatory.

Food, clothes, shelter, help to save precious heirlooms, those are all inflexible needs.

Borrowing on "social credit" on inflexible needs can be exploitatively steep later.

In the Yakuza-as-"helpers" model, they're taking advantage of chaos and economics theories.

I think you can see what is really happening if we switch out "Yakuza" with any outlaw criminal organization in the States like as in "During the floods of '22, I got help to save my photos of my great grandparents from the Gambino's...", or "During the hurricane and disasters of '22, I needed antibiotics for my daughter, the Hell's Angel's helped me..."

skylanh··on Everything you need to know about monorepos
I think... it has been. OTOH, if you cycle to the end, it's a collaboration by the developers or "community outreach" of those tool chains:

"The tools we'll focus on are: Bazel (by Google), Gradle Build Tool (by Gradle, Inc), Lage (by Microsoft), Lerna, Nx (by Nrwl), Rush (by Microsoft), and Turborepo (by Vercel). We chose these tools because of their usage or recognition in the Web development community."

Contributors:

- Alex Eagle / Bazel

- Kenneth Chau / Lage

- Jeff Cross / Nx

- Victor Savkin / Nx

- Pete Gonzalez / Rush

- Justin Reock / Gradle

So, yeah, it would be a focused website.

skylanh··on Signal users can give a recurring monthly contribution
Firstly, Random websites tell me that each Facebook user is worth on average ~$35/year on revenue figures--no indication if that was net or gross.

So, ~$5/month gross costs is appropriate when comparing it to deferred "you are the product" and taking into account cryptographers, developers, testers, system administrators, infrastructure administrators, team leads, program leads, and adding in physical infrastructure and network interconnections.

Otherwise you're just valuing against your own perception of "how much is my disposable income", which is different between any economic zone. And that's a poor argument when some people's concept of a steak dinner is a McLaren 720s that's disposable after a month.

Secondly, there are payment processor margins to take into account. At ~$60/year on 12 payments a pre-authorized standpoint, that may be less than on 1 payment of $10. I'm not interested enough to check.

This has been an argument for at least 25 years that I've been around this stuff.

skylanh··on Microfibers Released into the Air from a Household Tumble Dryer
My clothes dryer was broken for a time while I waited for a replacement and to install the new one.

In the interim, I replaced the dryer with a chrome (Ikea) shelving unit, a vapour barrier shroud (literally 5mil plastic), and a regular house dehumidifier.

For a full load of towels--or any heavy water absorbing material really--run times were about 2-3-5 hours. Clothing would be brought to the whatever humidity value "Continuous Operation" would cause. In general I assumed that was lower than line drying would cause, but less than line drying with direct sun exposure.

There was some effort involved in sorting clothing onto shelves. But very little real effort. About as quick to shelve and unshelve a full load as... well, doing just that. (10 minutes?)

I would probably avoid this with clothing that rest against high-bacterial load, high-smell areas (armpits, feet). Or more importantly, change my process for washing those items.

It would be a relatively straight-forward process to build a large drum machine based on an industrial dryer barrel, and attach an inline dehumidifier, and then run the drum in an intermittent mix mode.

skylanh··on You Feel Like Shit
I find when I have a strong negative or positive reaction and subsequent outburst, that I have some form of conditioned behaviour. This is usually a sign that I should try and catch that reaction, find the cause, and try to analyze link.

At least this is how I view it--the keys are: 1) strong reaction, 2) try to find out why I have a strong reaction.

skylanh··on The Steel House Saga

skylanh··on How to design a house to last 1000 years
> author has thought a lot about materials and buildings

> but not actually built anything.

That was my impression. As soon as they started talking about unenforced concrete pilings (drilled? monopile?) to bedrock and stressed steel framing I wasn't certain I would enjoy anymore or that it was a good use of my time.

I think costs at this stage are unrealistically low "probably in the neighborhood of $1000-2000 per square foot ... (8 to 16 times as much as conventional construction)". ~$250-400 sq ft is the cost of modern labour expediated and material optimized building. They're describing stainless steel framing with what would be (what?) 316 SS in S-beam with a custom end plate? A blob of rolled 1" x 6' 316 SS is $200.

There are the examples we could draw from:

https://en.wikipedia.org/wiki/List_of_oldest_known_surviving...

https://en.wikipedia.org/wiki/L%27Anse_aux_Meadows

https://en.wikipedia.org/wiki/Ancestral_Puebloans

Material wise we'd look at clay, solid high-density rocks, non-ferrous metals (lead, aluminum, copper, tin), dense naturally mold resistant woods (cedar, redwood), high density with high oil content woods (https://en.wikipedia.org/wiki/Lignum_vitae), and easily replaceable sacrificial surfaces, dirt with live plant, cobble rock.

Building techniques aren't going to improve with technology, we already have examples that have lasted -- we're looking at building a heap temple with ancient style water and sewers. This is either a rock temple or a log-house with highly resistant woods.

Either we aim for a light-weight footprint or we find solid rock for building on. Solid rock is the most appropriate.

Our fasteners are all based on managing gravity. Rock with concave and convex connections under gravity. Wood pegs in non-load bearing configurations. Lead sheets with crimped folded seams. Solid copper sheet trays with crimped folded seams in rock trays.

The first thought should be "what happens if I drive a truck into the side of this building 10 times?" And the answer should be "not much, you move a few things around, but there is limited stressed coupling, and things rest on top of each other." If you do substantially damage the building, all you should be doing is reassembling the pile.

I called the author out for not having built anything, and in honesty, I haven't built using these ancient approaches, so, perhaps this is a self-destructing prophecy.

skylanh··on Rust Moderation Team Resigns
Do you mind sending me in the right direction for more info?

I was around for the infancy of Linux (I remember a friend was running ~2.1.98 because it came out before Win 98 or something like that, even though it was occasionally unstable for them), and then went in another direction, and have recently gotten back in.

skylanh··on Offline First
Trucks or vans with 4x4 drive are pretty common in Mexico, Brazil, the middle east.

You're falling into the same trap that the article and GP's are highlighting: your experience that a FWD vehicle is enough "for me / my relatives" does not apply to this situation.

1) survival in animal / vehicle collusions with bears, deers, and moose

2) delivery of goods, including building material, animal feed, human food, etc

3) lack of even basic road infrastructure maintenance by government or municipality

4) "over prepared is only prepared", you're it, you're on your own

I lived for 20 years in a semi-rural area; you could certainly live for 99% of the time without a large cargo vehicle or 4x4. The other 1% you were chancing your life. Cargo and deliveries were certainly an issue though. Now just slide that ratio towards the middle.

I would personally use something like DxoMark's tests as a starting point to evaluate cameras and lenses. EDIT: and such things as the camera on a smartphone.

That sets the starting point, and then I can compare as I go along.

skylanh··on Why can't we just give steroids to people with muscular dystrophy?
There are a number of responses that don't make me comfortable.

The clearest reasoning for why anabolic or androgenic steroids' are NOT given in the context for recovery strength or function in a professional medical setting are that:

- it has unintended consequences that can be severe

- it has unintended consequences that can be long-lasting

- the expected consequences of use are more harmful than the regular recovery

- and that these can be quite harmful, enough that the use of AAS isn't necessary.

and finally the primary goal post surgical:

> One of the most important considerations in selecting operative versus nonoperative treatment is the risk of rerupture. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7031433/

Quite a few responses are getting into details of AAS use that isn't quite correct based on my understandings.

skylanh··on NASA can't figure out what's causing computer issues on the Hubble telescope
I think you have an interesting idea, but might not be thinking of the physics involved.

> The minimum distance from the Earth to Mars is about 54.6 million kilometers. The farthest apart they can be is about 401 million km. The average distance is about 225 million km.

Loosely, the speed of light is ~300,000km/s. So 182s, 1333s, and 750s as an absolute minimum length of time from end to end.

So, there are varying orbits, that's one problem. The other problem is getting items into solar orbits.

I didn't think of this, but now you have an even bigger problem of trying to keep those items in some sort of array that is in a direct line between Earth<->Mars.

If we hand-wave away that problem, the next problem is that each hop is adding latency, so, the direct answer is: no, it makes things slower, and it's a significantly harder problem than just communicating across that distance.

skylanh··on NASA can't figure out what's causing computer issues on the Hubble telescope
Another comment keyed onto a concrete example of why not, so I'll go with a presumptive reason:

Some of those elements will be part of the major service windows, and have expected operational and standby lifetimes.

So if a component with two elements has a service window of 10 years, and each element contributes to meeting that service window, then you've bumped your major service window from 10 years to a significant factor less than that.

e.g. the expected use profile might be: use element 1 for 6 years or 60% of service, switch to element 2 for 4 years, replace both during 10 year maintenance window. Interrupting that by bringing element 2 up reduces that window and contingency plans if the service window cannot be met.

I don't know, and I'm just talking out my you-know-what.

skylanh··on Brain imaging before and after Covid-19 in UK Biobank
> Here, we studied the effects of the disease in the brain using multimodal data from 782 participants from the UK Biobank COVID-19 re-imaging study, with 394 participants having tested positive for SARSCoV-2 infection between their two scans.

782 participants, 394 of which had positive tests for COVID-19, a further 15 of the 394 were hospitalized due to their symptoms.

The interpretation could be:

- lung symptoms are not correlated with brain changes

- mild infections not requiring hospitalization showed similar pathology to severe infections

skylanh··on What would you pay for autonomous driving? Volkswagen hopes $8.50 per hour
I think it's interesting that you have a somewhat valid point for a few use cases, but are quite myopic to the different users.

If I add in:

- I have children

- Temperatures range from -15C to +5C to -15C on the same day, and same outing

=> I need to pack backup clothing for the children in case they get wet in the +5 weather, and backup snow winter clothing for when it's -15 and they get wet.

=> We aren't talking niceties, a 25kg child exposed to sub zero weather in wet clothing will approach hypothermia and other detrimental conditions quickly.

If I add in:

- physical limitation including breathing (reliant on oxygen), exercise intolerance, amputation, pregnancy, pregnancy induced physical limitations, broken limbs, nerve damage, inner ear disorders due to concussion or older age

=> "So are your legs. Walk and bike." becomes... well, I hope you see.

skylanh··on EFF sues Proctorio on behalf of student falsely DMCA'd
Anecdotes in support of this comment:

I lived with a orthopedic surgeon doing a specialization in pediatric orthopedia.

He was very very very good based on my understanding of the places he had worked, the offers he had to undertake his specialization, the change in operation waiting times and his model of how he worked within the hospital, and that immediately after returning to his home country he was head of the newly created orthopedic pediatrics ward.

His description of how he would approach a surgery was straight-forward:

- he would review the surgical referral, his notes from his patient intake

- he would review appropriate notes and documentation from the hospital on the allowed surgeries allowed, including reference texts on that particular surgery

- he would create a full plan for entering, performing, and exiting the operation

- (surgery)

- he would review the plan, add notes on how it actually went

So it's not like he woke up, walked into a surgical room, and ad-libbed it.

As an anecdote, he said he liked B-students for his surgical teams because they had to work hard to get there.

I also was good friends with a very nerdy emergency room doctor. He offered the anecdote that he was "called out" for using Google. His justification was that "once you throw in the appropriate medical terms, all you're getting is the latest research on treatments--and I was attempting to offer the best and latest in proven care". He also made the several changes to the shifts at the ER, including using time-sheet and patient data to show that patient outcomes suffered during longer doctor shift rotations. His anecdote on his schooling; "I was a bad student, and I'm a poor doctor, but my job is to get you stable until we can intervene properly". He funded a startup and wrote (in Java) a medical EMR system.
