> But my parents' house was built in the 80s, and has always had serious problems with the upper level being much hotter than the lower level.

Sounds similar to my parents', which was built in the 70s, in IL.

<story time>

Last summer I visited and ended up doing a bunch of deferred home maintenance on the place. One thing I discovered was that the central air return vents weren't installed correctly, after 50 years of them paying out the nose for unnecessarily high electricity bills every summer.

The construction technique used was clearly prioritizing low-cost and had the main return duct running the length of the house above the basement ceiling just opening up on top into the floor joists to reach rooms upstairs. The bays between the floor joists served as ducts branching out horizontally from above the main duct, and holes were cut in the upstairs subfloor where the stud bays in walls would serve as return ducts on the vertical axis.

When they hung the main duct they left a huge gap separating the thing from the joists, upwards of two inches wide towards the far end from the air handler which was also beneath the vertical branch for reaching the highest/largest (and hottest) return vent upstairs.

So despite having all these return circuits ostensibly present upstairs, the main return duct just pulled most of its air through this much closer and substantial gap drawing air from the lower level between the basement ceiling and the upper floor's joists.

Everyone had always assumed the cold downstairs was expected because Basement, and that the upstairs was just always hot in summer because of poor insulation and all the windows.

The way I identified the issue was by grabbing a long grocery store receipt and placing it across all the return vents while the AC was running (just get the blower on 100%). The receipt was nearly sucked through the basement return vent, and immediately fell off all of the upstairs return vents except the one directly above the air handler in the master bedroom. The one upstairs that worked doesn't depend on the long, leaky return duct. Then I fully blocked the obviously working return vents with cardboard, just to see if the non-working ones would start drawing enough to at least hold up the receipt - they didn't, zero change.

I was able to improve the situation with a can of expanding foam filling the gaps on the main return duct, through drop-ceiling access... If I visit again I'm ripping out the basement ceiling to fix it properly.

TL;DR:

If you've got a house w/central air that seems to not cool specific regions, get yourself a piece of thin paper like a shopping receipt and some cardboard and try some process of elimination to verify the return vents are all sucking air. Don't just focus on output vents blowing cold. You can do this preliminary check without any tools or creating a mess, fixing what you find might be a different story though.

Although I'm very positive about my graduate advisor, I do see similarities in my PhD field in general. I'm still trying to figure out what is the goal of academia. It's not about finding the truth.
> According to Moravy, vehicle assembly processes haven’t changed in the last 100 years, which he says is “really silly.

Where to start with this article?

Here is a good spot I guess.

First off, Moravy is wrong.

If anyone thinks that auto manufacturing and the "vehicle assembly process" has not substantially changed in the last 100 years, then they are totally ignorant of the industry and of the exacting details associated with something as complex as automotive manufacturing.

The other vital thing that this article fails to mention at all is how manufacturing is shaped by the larger concerns of the product lifecycle - which is (or should be) the actual "product" that leaves the factory.

"The car" is just a hunk of metal that embodies the product lifecycle - which can be competitively unique from manufacturer-to-manufacturer.

One cannot talk myopically about "costs" and whatever happens on the manufacturing floor without bringing in the total concerns of the product lifecycle (i.e. service, end-of-life, market requirements).

That is difficult to do in an article because the total size and complexity of each automaker's product lifecycle is immense (and largely unknown externally from the automaker in question), but it must be done.

> If something goes wrong in final assembly, you block the whole line and you end up with buffering in between.”

Which is how, fundamentally or in part fundamentally, the Toyota Production System works - and it is difficult to argue with the quality results at Toyota.

Honestly, I am not seeing much of a difference here overall.

There are various component assembly lines that do run outside and "in parallel" with the General Assembly lines at incumbent automakers.

I am not even sure how this is debatable.

> “However, there are some quality-related risks involved, such as potential gaps in fit and finish,” warns Pischalnikov. (snip) “The reason that’s always been done is for color consistency, to ensure that there’s a perfect match between the doors and the rest of the car body,” Prasad points out. “By not having to assemble, disassemble and reassemble vehicles, you can reduce production costs and eliminate waste.

Which are quality control aspects that Tesla still seemingly struggles with, near as I can tell.

I am all for encouraging automakers to explore new methods of automotive manufacturing and BEV production will present significant opportunities to do so, but this article from Assembly Magazine is, at the very least, incomplete.

I live in Montana. This means that a 500 mile EPA range (which i read as 500 miles on a mild day with no accessories activated) is going to mean a real range of around 400, cut down to 200 when the weather inevitability drops and stays below -10f (Tesla owners in MT were reporting exactly that - half the range in the cold weather).

200m, if you allow for an emergency buffer, can be a trip from home to the city around here. Or going from one city to another.

Texas offers similar length trips, just with AC instead of heating.

>The screen on my phone showed that the alarm I had set was in the process of ringing, but for some reason, the phone wasn’t vibrating or making any sound.

And this is kind of an example of why it will be impossible to mitigate Climate Change.

When I was young, clocks did not requite any power from the grid. It wound them, set the alarm and you heard it. Now we have faucets, toilets that use power to turn on/off and flush. Almost everything that was manual (mechanical) is now powered. That power needs to come from somewhere. In these examples, there is no real reason to have faucets, toilets and alarm clocks connected to the grid.

Yes, I know in the case of the Cell Phone Alarm, it is probably a wash, but a mechanical clock in your house is probably a good thing to have.

While widely used symbols like “eagle displayed” or “lion passant guardant” are really well defined, the more you get to the esoteric stuff the more you find there are really no standards. Try “importing” such thing as “octopus proper”.

Heraldically speaking, it really makes no difference, as nobody would mistake the “wrong” flag of Vatican to represent some completely different entity. But TLA is not implying that — just asking for some more standardization of a widely-used symbol.
I wrote one, though it kinda got away from me (I started very simple, but then started turning it into a Ruby compiler):

https://hokstad.com/compiler

On that note, while there's no new part, after finally revisiting it for the first time in a couple of years, it now compiles itself (from Ruby into 32bit x86).

A few very critical bugs that I'm working on, and a lot of big omissions (no Regexp yet; the Ruby Regexp engine source is bigger than my entire compiler, nor any Floats; syntax lacks a lot of newer features) so it's very much not a usable Ruby at this point. Maybe one day if I get more time.

If you find it interesting, I'd recommend looking at the earlier parts rather than the current source. Lots of the recent changes were very aggressively working around bugs to move it towards self hosting, and it's not pretty.
I live in TX and I sometimes wonder about the same- how did anyone lived here 100 years ago (or why they thought it would be a great idea). The best I could come up with - they just dealt with it. High temperatures meant staying in shade and sweating more. You can do only so much structurally but there are weeks when it doesn’t go below 90 in the night.
I assumed these fords would have both. But I guess I haven't seen anything concrete about it.

In the example you use (cristianmd7 OP) you should put a large X or make it clear the wikipedia example is the villain. Also put your example (what you write) in a larger color.

I would also include an about page with a writeup of your qualifications to be doing this (as specific as you want to get w/o personal info if you don't want it there).

Finally I'd also offer a service that is not a newsletter basically an 'ask me' type where a non tech person can email questions and get short replies.
I wonder if this is, in part, to the fact that we have an unknown quantity of time. It seems when people put a more finite value to it (through a prognosis, or even just regularly marking off 1 week of four thousand), they seem to attach more value to it. It seems to transition it from the abstract to the concrete.
Thanks for replying. Take a look, all three, including yours, read like textbook sales talk. I note someone took umbrage and has thrown their toys out of the pram.
So you are talking about a detonation, a specific type of explosion that involves a supersonic wave, almost everything you would see as a munitions expert would be one of those.

A dictionary definition of explosion is "a rapid expansion in volume associated with extreme outward release of energy", that includes things like, gunpowder deflagration, aerolized gasoline burning, or even a pressurized container (like a pressure cooker) rupturing. Film burning on a metal tin as they were stored could fit this definition pretty well.
What’s an example of an activity you’d consider debatable on whether or not it’s “questionable”?
I was very surprised by the company they chose for it, but from this perspective, it's definitely a great choice. If someone knows how to make things indestructible, it's them.

(Rheinmetall is generally known as a military supplier, think "General Dynamics" or "BAE Systems". I didn't realize they made anything for civilian use.)
Thanks - that sentence actually felt really good to write.
In American universities courses are typically numbered with four digits where the first corresponds to the year of a student's career, so freshman (1st year) courses are 1xxx, sophomore courses are 2xxx, and so on. The higher that first digit, the more advanced the course. (Since most bachelors degree careers are four years, courses that start with a 5 are graduate courses.)

With that context `Architecture 4031: Introductory Coreboot` is either a bonafide college course title or it's an attempt to sound like one.
This isn't always possible, but sometimes you can define what's called an improper prior p(µ), such that even if ∫p(µ) is not finite, the posterior distribution p(µ|x) is.

A common example is when p(x|µ,v) is a Gaussian dist. with a prior on the mean set to p(µ)=1.
We have heard this story before. A few years ago Tesla was building an "alien dreadnought" that would use 100% self-building robo-workers. This failed so badly they fell back on a circus tent in the parking lot. Their factories are piled with junk, plagued by safety violations, spew toxic chemicals, and their QC is so laughable that their cars are less reliable than Jeeps.

https://www.consumerreports.org/media-room/press-releases/20...

Tesla's problem is not scale. Their problem is that they cut every corner known to man in pursuit of scale. As a result, their cars are the lousiest shitboxes on the road.
I don't think it is really possible for everything to be 'above board'. I'm sure Ford receives plenty of complaints that they don't want published even if they are all baseless. When you have millions of cars on the road that is the reality.

Funnel has come in handy for me a number of times. Though I now wonder if the abuse experienced by Mullvad will be realized by Tailscale as well. Perhaps compounded by an exodus of Mullvad (ab)users seeking alternatives.

I love the sentiments and ideas presented. Thanks for putting these thoughts into words, and sharing. Not sure why some ppl interpret your post as some kind of militant set of demands. It's very thought-provoking and helps think about software and its creation/curation/usage in a different light. The deeply-instilled "corporate vendor -> money-expending user" ecosystem of software and computing comes with many costs, sociological, psychological and so on. Further, the ability to have agency over one's computing experience is basically constantly threatened by software vendors and constantly-lobbied regulators. I think it's wise to persistently question the status quo, especially when it is largely dominated by profit-centric intentions.
Holy Roman Empire really doted on those heraldic signs, with England and a few others, too. In German, the word for the heraldry banner is "waffen" which is the same word for actual weapons. In English, to say "Coat of Arms" says the same thing, if I understand it.

It's funny how differential equations just boil down to plain linear algebra when you restrict yourself to the discrete time domain setting. I feel like courses like this should lead with that to save time for people who will primarily handle them inside computers.
It's not ready to take a book, but I'm building an app that takes scans of book chapters/journal articles (which I often receive from my college library) and turns them into well formatted PDFs (with OCR, consistent margins, rotation...) https://fixpdfs.com
Wikipedia is too often the final source of truth for people. While I'm not saying it's intentionally wrong very often, but accidental wrongs get repeated elsewhere. It happens especially with things like the Vatican flag ("Surely Wikipedians haven't fabricated some alternate version?").

Another example: The Windows Me logo (yes, seriously). At the bottom of the stylized "Me" are the words "Millennium Edition"; Wikipedians like to recreate logos into vector format. Unfortunately, someone had misspelled those words to say "Millenium Edition" instead. I personally fixed that image, but I still see the misspelled version crop up from time to time in articles, YouTube videos, etc (how are they still getting the wrong version? I don't know...).
Yes the article is bs because your argument is that there aren't many physicians and maybe the insurance companies complain for costs and this is humongous vastly different than prevention and erly screening is bad.

100% agree with you, having been in and around automotive factories for years. Tesla is really capitalizing on two things here:

1) Tesla customers seem extraordinarily willing to overlook production defects and servicing/repair issues compared to customers of other OEMs. This lets them get away with lower manufacturing quality tolerances than they normally would, as noted in the article mentioning the water ingress issues. Seems like they're going to further capitalize on this customer tolerance with the paint process changes.

2) As a result of only building BEVs with no legacy support requirements, Tesla is able to design the manufacturing process and vehicles themselves to be more efficient to assemble. It's a definite competitive advantage today and that's another thing some of their intended changes here will try to capitalize on. The question to me is how long it will be until the traditional OEMs catch up here.
Nice, I learned something and thank you

It was a joke: when Seymour was informed that Apple was using a Cray machine to design their computers he said something like "funny, I use an Apple computer to design the Cray". But in reality he never used computers at all but did everything with paper and pencil.

Tailscalar here: your own CNAME won't work because of how the routing logic in funnel works. When tailscaled sets up a funnel with the control plane, it uses the derived DNS name from your tailnet (eg: pneuma.shark-harmonic.ts.net for the machine pneuma on the tailnet shark-harmonic.ts.net). As far as I understand there's no issue currently tracking this work.

Tailscale Funnel does allow you to use any TLS-wrapped protocol (IE: one where the client does TLS and the server can optionally listen over plain TCP), but I'm not sure it would really meet the same goal as port forwarding in Mullvad does (for one you could use any non-TLS or UDP protocol with Mullvad port forwards, IE: Minecraft server hosting, Minecraft doesn't use TLS afaik). It's great for HTTPS though. I'm not sure how the bandwidth limits would add up over time for something more interactive like Minecraft.

Either way, Funnel does do some things well, but it's not a generic replacement for Mullvad port forwards.
> Secularism is a constitutional principle

The constitution can say whatever it wants. The only thing that matters is what actually happens on the ground. Successive governments have adopted Hinduphobic positions and laws while claiming to be secular. Why are only Hindu temples under the control of various state governments? Why don't governments take similar control of cathedrals, churches and mosques?

There is example after example proving my position. All you have is some words in a document that are belied by the actions of those meant to observe it.

> Right to Equality

Religious minorities can run their own schools where they can teach their children their way of life? Can Hindus do this qua Hindus? Again, words in a document that contradict other words in the same document.

> Hindu Marriage Act (a personal law) was amended to outlaw polygamy

Why were Muslims not given the same benefits or punished in the same manner (whichever way you want to look at it)? How can you be secular and equal if two men or two women are treated differently before the law for the exact same action? This is a joke masquerading as justice.

> Of course, the fascists will equate all proselytizing with forcible conversions.

You can believe that Christianity is so superior to local religious practices that an entire state almost completely adopted the religion voluntarily in 3-4 generations. Given the history of Christian missionaries in India, South America and other parts of the world and the tactics they adopted, this is a simplistic argument/position.

There is literature available from Missionaries, in their own words, as to their opinions about Indian religious traditions and the people practicing them. Arun Shourie has written a couple of books on the subject.[1][2]

An individual here or there converting to a different faith is one thing. When religions conversions are used to shift demography, this has national security implications. Separatist movements grew in Kashmir and Nagaland. The partition of India was done on Muslim vs. non-Muslim lines where Muslim-majority provinces became Pakistan. Onlygodists will always be in conflict with Manygodists because their worldviews are fundamentally different.

Organized conversions must be banned. If the constitution has to be amended to do it, so be it.

Apple is fine with respect to AI and doesn''t need to hype up their AI efforts.

They released this voice cloning feature, buried in the article without any fanfare.

https://www.apple.com/newsroom/2023/05/apple-previews-live-s...

Their strategy is the same:

1. Wait for all the other competitors to release their first implementations of AI. (Apple doesn't care about being first)

2. Apple learns from their competitor's mistakes.

3. Apple rolls out their on device AI solution and gets it right.

The fact that Apple is too quiet whilst the competition is likely using OpenAI and other hosted AI models is already dangerous for many startups.

Once Apple releases their solution, what usually follows is Google will do the same with Android.
