_xerces_··on Tesla conducting more layoffs, including entire Supercharger team
Most jobs in the USA are "at will" meaning there is no contract and either you or your employer can decided to terminate the arrangement at any time for any (legal) reason.
_xerces_··on Airlines required to refund passengers for canceled, delayed flights
One issue I have had is where they cancel the domestic final leg of a non-direct international flight. The total ticket cost was $2000, but they valued my cancelled final connection at only $40, yet if I tried to purchase just that flight alone between those two US cities, it would have been more like $400.
_xerces_··on I rewired my brain to become fluent in math (2014)
I think there is another one, Math C that involves day-to-day mental arithmetic which I am terrible at despite being good at Math A and holding engineering degrees. There might also be another element of Math C which is a feel for numbers and lets you know if an estimate or the value staring at you on the calculator screen makes sense or if it is obviously wrong.

I tie my poor mental arithmetic skills partly to never properly learning multiplication tables, at least not all of them and perhaps something lacking in my brain which also means I have a terrible sense of direction.

Yet, when it comes to symbol manipulation where the numbers don't matter until the very end, then I am good at that.

_xerces_··on Work begins on a $12B high-speed rail line between Las Vegas and Los Angeles
See the Silver Line on the DC Metro, and several other lines that run in highway medians. It is not a new thing.
_xerces_··on 'Expensive' Streaming Services Are a Key Reason for Americans to 'Pirate'
Google has a useful "Where to watch" feature in their results for a lot of TV shows.
_xerces_··on FTC announces rule banning noncompetes
CA already makes non-competes unenforceable and aren't most FAANG employees in CA?
_xerces_··on It's cutting calories–not intermittent fasting–that drops weight
One of the arguments was that you improve your insulin sensitivity because by limiting your feeding window, you are not constantly eating, snacking for 16 hours a day and causing multiple spikes.
_xerces_··on How many bathrooms have Neanderthals in the tile?
I found out not long ago that Time Team episodes are officially available on YouTube, both old and new:

_xerces_··on Tesla drops FSD price to $99 per month in US
I have heard that Tesla does not use the capacitive touch/sense technology that other automakers use and so relies on detecting the current increase or something from the driver wiggling the wheel or slightly moving it.
_xerces_··on Amazon virtually kills efforts to develop Alexa Skills
That was the killer feature for me. Being able to yell "Alexa, put milk on the list" right as I poured out the last drop was very convenient. For larger lists like recipe ingredients I used the web interface. I still use it via the Windows app (which insists on grouping my items even though I keep turning it off) and my phone, but the experience and interface has gotten worse over time. I wonder if I can get similar functionality from Google.
_xerces_··on Ask HN: Why are there no no-name inkjet printers?
Inkjets are complicated, hard to get right and companies that make them have to hire electrical engineers, software engineers, firmware engineers, hardware engineers, mechanical engineers, chemical engineers, experts in microfluidics and more. Not to mention, I bet a lot of stuff is protected by patents owned by HP, Funai, Xerox and Epson to mention a few.

Add to that, the market model is mostly a "razors and blades" model where you sell the hardware at or below cost and charge more for the ink and everyone hates you for it.

_xerces_··on The unreasonable effectiveness of VMs in hacker pedagogy
He doesn't want me to have to go figure out what Docker is, but now instead I have to figure out what Vagrant is or does, he doesn't say. I go to the Vagrant site and see: "Single workflow to build and manage virtual machine environments"

If I was new enough to not know what Docker is, I am pretty sure I would be a little confused about that. I don't want a "workflow" do I, I thought I was trying to follow a tutorial. Do I need to "manage virtual machine environments?". Do I need to install both Virtual Box and this Vagrant tool?

I think this is a nice idea and useful, but I wouldn't couch it in terms of being some great technique for beginner tutorials.

_xerces_··on Boom announces successful flight of XB-1 demonstrator aircraft
Why would a couple of cameras and a screen be an insane feat of engineering? I spent a lot of time watching on the back of seat screen the tail cam and front camera of the A350 I flew on recently. One issue the Concorde had was poor visibility out of the windows which they solved by having a moveable hinged nose, cameras make this issue go away (assuming there is good redundancy)
_xerces_··on Study: Higher gut bacteria diversity associated with lower risk of infection
I have read that certain foods such as walnuts can 'feed' butyrate producing bacteria, but I wondered how one can increase their numbers. From the article, that sounds difficult:

" One of the challenges is the face are the butyrate-producing bacteria are strictly anaerobic (meaning they respire without using oxygen and cannot tolerate oxygen), which makes it very difficult to transport viable bacteria into the gut. Several research groups are working on addressing these challenges. "

So maybe the trick is to use diet to select from those that are already there so they outcompete other species?

_xerces_··on 5GSimWaveform: Open Source Common Waveform Simulator for 5G Physical Layer
You can simulate a 5G base station or phone on your laptop and have them talk over your network or localhost. You can even use an SDR to have them talk over the air (local laws allowing)

https://github.com/oai-group/openairinterface5g

_xerces_··on 5GSimWaveform: Open Source Common Waveform Simulator for 5G Physical Layer
You can simulate a 5G base station and/or a phone (UE) with this software and have them talk to each other over your local network or localhost

You can even use an SDR to create a real base station or UE (local laws allowing) at home.

The tool has logging and quite nice plots that show the constellation diagrams, signal decoding, etc.

_xerces_··on 'Britain's Pompeii' reveals Bronze Age village frozen in time
Reminds me of reading Asimov's books set in the distant future and they still use tapes and other things from the 1950's. Maybe if pressed he could argue that the technology in the future was vastly different, but wanted to use the name of a storage media his readers were familiar with and avoid having to make up a new word.
_xerces_··on Astronaut Thomas Stafford has died
It seems a lot of astronauts, at least the early ones live long lives. I wonder if it was because the selection process weeded out anyone with any sort of health condition and anyone who was not at peak physical fitness.

_xerces_··on Why are most sofas so bad?
Are you not worried about bedbugs buying furniture off Facebook?
_xerces_··on Twenty years is nothing
Reminds me of an old joke among auto enthusiasts: "How do you know if someone drives a manual transmission? They'll tell you".
_xerces_··on "AI will cure cancer" misunderstands both AI and medicine
Just a few snippets that use language typically used by those on the further left with a bit of an agenda. I am kind of center-left myself, so I agree with some of the sentiment, but I tend to think that a lot of the issues they ascribe to purposeful, scheming evil actors are often just defects in how our society works on a macro scale.

- "AI is used to disproportionately benefit the privileged while worsening inequality"

- "the goal is to increase corporate and government revenues by denying poor people resources"

- “It is a pattern throughout history that surveillance is used against those considered ‘less than’, against the poor man, the person of color, the immigrant, the heretic. It is used to try to stop marginalized people from achieving power.”

- The same pattern is found in the role of technology in decision systems.

- "The goal of many automated decision systems is to increase revenues for governments and private companies"

- "here is already a clear pattern in which AI is used to centralize power and harm the marginalized."

_xerces_··on "AI will cure cancer" misunderstands both AI and medicine
I dislike these articles that end up being written with a leftist bias that AI is already being used to [purposely] control and marginalize people. There are definite inequalities in society including in medicine and these biases I am sure make it into training data. However, while we should be watchful, I don't think there is a conscious decision by "the man" to purposely put certain groups down using AI. AI researchers themselves and doctors are a pretty diverse group.
_xerces_··on Ada 95: The Craft of Object-Oriented Programming
I think Ada, due its DoD origins and mandated use in some defense projects is more common than Pascal or Modula-2.

Funnily enough though, I took a basic computer science course back in 1995 where Pascal was the first language that was taught! I still remember the instructor telling us to imagine how we would instruct an alien how to use a vending machine, we could not assume it knew anything and had to lay out each logical step and it would do exactly as we told it, so we better get it right. He said that was the mindset we needed for programming.

Fast-forward to 2004 when I resumed my further education and now the first language taught in that university was Visual Basic, followed by Java for the object-oriented programming class and then straight into pure C for Operating Systems which was a bit of a jolt. Oh, and then back to Java when we had some horrible UML class with design software that auto generated code.

Apologies for the off-topic meandering, the mention of Pascal brought back memories!

For the lazy or short of time, does with worth with tldr pages :) https://tldr.sh/
_xerces_··on Scientists get closer to solving chemical puzzle of the origin of life
I wonder if AI could help us with the problem of how life started. Either through simulation or some extension of existing programs like the ones used for drug discovery and protein folding. I know AI is not some kind of panacea for difficult problems, but it might be able to suggest things like the experiment detailed in the article and predict results.
_xerces_··on The aerodynamics of a turn: How an airplane turns
It could be an oversight because the intended audience is pilots. I think the answer might be that nose up increases the chance of a stall, so more power is added to increase airspeed and therefore lift. I'm not a pilot though, I found this article when trying to understand how simply tilting the wings causes a turn.

Use an infrared spotlight and sensor?
_xerces_··on Man convicted for trying to help undercover game wardens recover deer with drone
Not mentioned are FAA rules on night flights, flight out of line-of-sight, flying drones commercially (licensing required) etc. So this could end up being federally illegal no matter what PA decides.
