That's your argument? That modern psychology and psychiatry is incapable of diagnosing debilitating conditions like schizophrenia in an individual living in a filthy tent-city - therefore we should err on the side of caution to such an extent that we cannot make a judgement call on anybody?
One huuuge difficulty is that a lot of computer stuff is dependent on the era you’re using it in.

If you take a computer now, you’ll end up using modern websites, stuff like Slack, etc, which will not mech well with older form factors or software.

Meanwhile my grandparents had a computer with XP, Diablo 2, and .... codeBlocks? The C/++ IDE.

Many years beyond a lot of this software, the computer experience is still pretty excellent. Especially when i can turn on a radio next to it to close off the last piece (having some music to listen to)

It’s been many years since I’ve used that machine , but it was great because I wasn’t trying to use the machine to watch YouTube or use Twitter

We think Buck is great.
It's Deterministic hermetic builds and it's composable and declarative high-level build description language made packaging very easy.
We built even built a package manager for Buck:
https://github.com/LoopPerfect/buckaroo

Currently we marketing it for C++ but it can be used for any language that is supported by Buck.

I'm going to nitpick. The original sentence is grammatically correct in the UK and some other non-U.S. English speaking parts. I know this may sound very weird, but it's all fine and correct somewhere else, treating companies and establishments as plural.
Well, it's definitely not as complex as a lambic.

But that's OK, sometimes you want a simpler beer and sometimes a more complicated one.

>You state this like it's obvious,

But it is. We do that all the time like, for example, during criminal proceedings. We understand that an individual with particular mental handicaps may not be fully (or at all) capable of making rational decisions and therefore should not bear the full responsibility for their actions.

>when what they really need is better community treatment.

What do you think 'community treatment' means!?!?!? You let them live in a filthy tent, with no clean water, no sanitation, no protection from the elements, with an occasional visit from a social worker to make sure they don't have cholera and have a blanket so they don't die from exposure?? That's your definition of 'community treatment'???
It's almost like human health and wellness shouldn't rely on the economy!
Not a bad idea but a few things to keep in mind.
- The sample rate on an Arduino is pretty low, depending on which model you have it may only be a few MHz and the absolute best you can theoretically possibly achieve with your home o-scope bandwidth is half the Arduino clock frequency. You'll also have to cast off the Arduino language and start moving to C/assembly to get the full performance out of it.
-The dynamic range on the Arduino ADCs is pretty low. It's going to be limited by the number of bits in the Arduino ADC.
-The input on an Arduino ADC is going to be either very low or very high impedance. This is also common on lower frequency scopes (low frequency in the case being 1GHz or less bandwidth) but if you try driving your input directly the impedance mismatch from the RF is going to cause poor signal and lots of noise on your measurement.

I don't know what SDR you have but it might be suitable for the signal capture and you can probably gin up some filters in post processing to approximate a Spectrum analyzer. If you have a source and 2 directional bridge couplers you could use it to make a poor mans Scalar Network Analyzer. A noise generator or a swept tone (Chirp) can be used in both these cases. The article you linked basically did a 1-port Network analyzer using the bridge coupler and used to to measure VSWR.

A lot of modern oscilloscopes, even hobby ones, now include the ability to capture scope traces to a PC and an FFT math function. You're going to be limited in frequency without a downconverter but it's a good way to go on a budget when working on a bench. The Rigol's are a lot better than they were when they first came out and make a good hobby scope for a reasonable price. If you can be spendy, the Keysight hobby level scopes are a joy to use. Best bet on a budget is to troll the internet for an old Tektronix, Lecroy, or HP/Agilent/Keysight but you'll probably not get something with fast trace capture or a built in FFT.

All of that said, making test equipment out of your Arduino is a great hobby project that will teach you tons of useful engineering. I highly recommend it!
My Duchesse never lasts that long: I like it too much. But I start drinking it only when it's warmer.

I even managed to get it on tap on a few occasions.
AMOS-6 suffered from a problem with a Helium Composite over-wrapped pressured vessel (COPV) that most likely had a liquid oxygen intrusion into the composite layer which due to the cold temperature of the helium created oxygen ice that violently reacted with the composite when friction ignited the combination. (Fun fact: as far as I know a liquid-oxygen drenched cigarette basically explodes when lit).

Afaik there is no Helium COPV on Crew Dragon.

Edit: after checking because of Someones comment, it turned out that cigarettes do not explode when drenched with LOX, they just burn brightly not unlike a flare.

> All the CO2 they exhale got the carbon from plants, which recently pulled it from the air. Humans are carbon neutral.

This would be true AFAICT if we somehow managed to eat without any CO2 emissions. But agriculture is a huge driver of CO2 emissions and so are logistics, electricity for cooking etc.. So while the CO2 we exhale comes from the atmosphere through plants, animals and so on, we inevitably cause a lot of CO2 emissions as a side-effect in the process.
It is useful as long as they do not know what happened. NASA once had the problem that the initially suspected problem turned out to be wrong but the news was already out there and it took years to spread the correct one. That's why it these problems are now referred to as anomaly until the real cause is clear.
Yeah, but you get into that contract voluntarily, so you sort of know what you signed up for, and regardless, you have the option to quit. This is why I do not understand the complaints.

Maybe - Unless the bypass circumvents that. NSA did exactly that on Samsung (Tizen) TVs a few years back.

I ride a bicycle as my primary means of transport. I strictly obey traffic laws, and on almost every[0] journey I see motorists breaking traffic laws. Where I live, it's illegal to cross a solid white line that borders your lane to overtake somebody unless they are traveling at less than 10mph. I never travel that slowly, but motorists routinely cross solid white lines to overtake me. I estimate only about 1% of motorists obey the law.

To be fair, only a minority of those illegal overtakes are actually dangerous, but the same is true of most traffic law violations by cyclists.

[0] Extremely short journeys, or journeys very late at night, might encounter no motor traffic in a position to break the law.

I think it was the US Marine Corps who issued and reissued M1911 frames printed for WW2 until the pistol was finally phased out of all units in the 1990s / 2000s.

You could have had 3 generations of Marines using the exact same weapon. Unlikely of course, but not technically impossible.

My anedata for EU is that varies a lot between States.

In Germany, I had salary negotiation closer to what I was used to in the US (e.g.: two competing offers, etc).

In Denmark, very little room to maneuver. I had no luck negotiating salaries in big corps here (Final comp in DK mostly from salary). Every attempt I made to initiate a salary discussion/negotiation seemed to make the hiring managers uncomfortable as in “we don’t do this here”..

There's also been a remake of Colonization in one of the recent Civilization games, I think. (But not open source.)

I am still waiting for a good remake of the first Master of Orion. The science system was very clever and the absence of base micro-management left you attention for bigger points of strategy.

In most 4X games the technologies are arranged in some fixed acyclic graph. Colonization's founding fathers are different. And so is Master of Orion: the technologies are available in six ladders and you can research anything within a few rungs of your highest technology on that ladder. Each faction in each game has some technologeis randomly missing. Some technologies might not be in your game at all.

So you never knew whether you were going to get your favourite weapon systems or terraforming tech in your game. Or whether you had to trade / loot / steal it from other factions or whether you'd just not be able to acquire it at all.

There are some remakes of MoO, but most of them take their cues from the relatively much more bloated sequel Master of Orion 2.

https://web.archive.org/web/20181215171436/http://sirian.war... has some really cool write-ups and http://www.sullla.com/MOO/moo.html is a bit more recent.

“Rapid unplanned disassembly”
You are asking: how are they “pushing the limits of spaceflight technology?”

Let's not go futher, just concentrating at the incident in question. The anomalous test happened on a location named "Landing Zone 1". That's not a thing any other rocket company has. Why? Because they don't land their rockets.

It happened with a space capsule fished out of the brine. No other company reuses their space capsules in such a way.

The detonation very likely will be found to have something to do with the SuperDraco system. Which they originally designed there to enable propulsive landing on dry land. The russians have their kick engines, sure, but that's not really same as hover landing, isn't it? Why did they plan that? For rapid reusability.

So yes, if you ignore all the things they did for reusability, then they indeed are not pushing the limits of spaceflight technology.
That's a good point, but given the search space is a set of voxels, you can probably brute force a yuge amount of possibilities and fit some sort of paramterized curve to them.

It is indeed magical thinking. "$200,000 worth of Tesla batteries, which collectively weigh over 20,000 pounds, are needed to store the energy equivalent of one barrel of oil. A barrel of oil, meanwhile, weighs 300 pounds and can be stored in a $20 tank. Those are the realities of today’s lithium batteries. Even a 200% improvement in underlying battery economics and technology won’t close such a gap."

Meanwhile the battery industry currently uses 42 percent of global cobalt production, a critical metal for Lithium-ion cells. 70% comes from the Congo where kids do their bit against 'climate change'.

Anomaly - something unexpected
Yes because they both work for the same customer (nasa) who will determine the type of process needed. When it comes to human spaceflight, nasa decides the pace of the investigation (number/nature of reports etc). They take accidents on the pad exectly as seriously as accidents in flight.
Reducing the pressure reduces the forces on the pressure vessel. I assume that only the oxygen partial pressure is actually important for respiration.

Don’t You Touch My Nuts: Information Hiding in Cyber Physical Systems
The IPCC (International Panel on Climate Change) is the generally considered the best source on climate change science. They have a nice graph of how things can go based on various amounts of sequestered carbon being injected into the carbon cycle.

Graph: https://www.ipcc.ch/site/assets/uploads/2018/02/SPM.05-01-1....

Report: https://www.ipcc.ch/report/ar5/syr/

It basically shows that if you assume we keep pulling carbon out of the ground (e.g. extracting and burning fossil fuels) we'll end up at +4.5C increase. That kind of change is likely an human extinction-level event (e.g. https://xkcd.com/1379/). The Paris agreements call for a max of +2C, which means we can only pull up about 25% of proven fossil reserves.

So we're going to have to leave 75% of proven fossil reserves in the ground. There's actually a term for this called the "Carbon Bubble", and it's expected to decimate the oil majors and sovereign oil and gas since most of their proven reserves on their balance sheets are going to end up being stranded. https://en.wikipedia.org/wiki/Carbon_bubble

Covert channel attacks in pervasive computing (2015)
As long as you have a passphrase and don't actually circumvent it (by e.g. an agent) you basically already have 2FA (you need access to the key (on your laptop/pc) and you need access to the passphrase (in your head)). But physical 2FA (like smartphone based ones or smartcard based ones) are nice because you can remove them from your computer or destroy them. You can't "destroy" a passphrase, so passphrase and sshkey are not really "independent".

Heineken is pretty good for an industrial lager. A lot of brands seem to cheat with the malt sheet or hop to make beer cheaper. Having said that, I just don't like lager/pils that much to begin with. Tried 20 in the Beer Museum in Prague that were very well made and only two or three hop forward ones I would order again.

> Eg https://belgium.beertourism.com/belgian-beers/duchesse-de-bo.... suggests you drink the Duchesse de Bourgogne at 8-12C. If you start at 8C and let it warm up as you sip, you'll notice the taste change over time and the flavours and aromas develop.

Same with Westvleteren XII. You're supposed to sip it over time. Lesser Quads don't taste great over the whole temperature range.
One of the reasons people are bad at tackling something like the changing climate is that the subject has been turned into something closely resembling a religion and as such has gained adherents spreading the true faith and detractors denying it, with almost no sane discussion being possible between the two. This is a sad state of things as it leads to totally illogical actions on both sides. Combine this with the clear and present danger from commercial interests trying to gain from either keeping the status quo or from selling new and often largely unproven - or even proven ineffective - ways to 'fight climate change' and the stage was set for the current situation.

This situation has occurred earlier in history, an example being the attitude towards nuclear power. While some point at the accidents in Three Miles Island, Chernobyl and Fukushima as examples of why nuclear power is the spawn of Satan and should be banished from this earth, others see those same accidents in the light of the stalled development of nuclear technology due to the actions of those who do everything to stall those developments leading to ancient reactors being kept on-line because their successors have been stalled or cancelled.
Whether that strategy works depends on the carbonation of your beer (and your preferred level of carbonation).

The warming up curves and going flat curves have to play together nicely.
Innis & Gunn is notable as being AFAIK the only widely available oak-aged beer where you can actually taste the oak. Well worth trying IMO.
Overall Buck and Bazel are quite similar as they are both converging to Starlark DSL.

However there are still some differences:
Buck is much more opinionated than Bazel.
Buck models slightly better C++ projects[1] and currently it's remote cache is more efficient[2].

Bazel is more extensible and offers also remote execution.
Bazel has a bigger community and it's roadmap is public.

There has been more than 350 C++ [4] libraries been ported to Buck for the Buckaroo Package Manager[3].

There are also technical details that manifest in some odd ways but are not significant.
There is a nice paper by Simon Peyton Jones (creator of haskell) and others that goes into the design details [5]

Labour rhetoric. The UK isn't "barely functional", that's a ludicrous communist fantasy that can be traced back right to Marx, who tried to convince his readers of the dire near apocalyptic state of England by committing various kinds of fraud - like making up quotes and attributing them to the PM, or relying on obsolete government reports into factory conditions. Those conditions had long since been fixed by the government's factory acts, but Marx couldn't mention that without undermining his central thesis that democratic capitalism was in a death spiral and couldn't improve the workers conditions, so he pretended he was citing contemporary documents.

Nor have "landowners already destroyed the economy of the country". The UK economy is the fastest growing in Europe right now (of the rich nations), unemployment is at record lows despite a long term massive influx of immigrants: its economy is literally the opposite of destroyed. You're lying about the reality of the UK, whilst criticising others for being naive.

Shooting down your trad-Marx rhetoric with economic facts is easy so I'd like to focus primarily on this oft-cited belief:

Beyond a certain point massive inequalities are inherently politically unstable and almost guaranteed to result in a seismic social dislocation. This isn't even a moral point - it's simply empirical.

But it is a moral point. The people who perform "seismic social dislocation" in response to (perceived or actual) economic inequality have a long history of performing that dislocation by shooting peaceful people, stealing all their stuff, building forced labour camps, liquidating all their political opposition and then turning their countries into hellholes. The communists who did all these things absolutely deserve moral condemnation and their acts cannot simply be whitewashed away as some sort of mechanical inevitability, no more than someone could excuse the Nazis as some sort of mechanical inevitability given the inequalities imposed on Germany by the Treaty of Versaille.

Compare the fate of every country where your views have gained critical mass vs America. The latter is one of the world's most successful countries, if not the most. The others are all slowly recovery from absolute poverty, and recovering only because they finally turned their back on your Corbynite views.
