Seeing as I once worked with RADIOACTIVE ASBESTOS (in a full anti-contamination suit with forced air) I can most certainly agree with you.

Are you talking about Charnobyl? That particular cold war accident was pretty bad, and yet the effect on surrounding populations (to the best of my knowledge) does not appear to be significant.
Animals currently live there. The forest is taking over the site. It's "habitable" although I would not want to live there. Most of the problematic radiation appears to be from Cs-137 but that's a group I metal and would form a salt (or a hydroxide deposit) and eventually wash away with rain. 30 year half life suggests that 150-200 years of "uninhabitability" is about the worst you can expect.
Most of the 2009 survey results were in the area of 1uSv/hr (0.1 mrem/hr). I regularly got 80-100mrem/year just being at sea level, without being around an operating reactor, when I was in the Navy (while underway under water we got LESS radiation from the reactor than people get from the sun). At 2.4mrem/day (or about 1 rem/year) you are actually BELOW the legal limit for being a radiation worker in the USA. So after 5 or 6 half lives (2^-5 to 2^-6) you can project the radiation rate will be 1.5% to 3% of that. Habitable.
Lots of info here including 2009 radiation measurements
http://www.chernobylgallery.com/chernobyl-disaster/radiation-levels/
Russia, Belarus, and Ukraine got most of the radiation. A lot went to Sweden but apparently did not cause any well known health effects
The best examples we have on serious fallout and habitability are Hiroshima and Nagasaki. Both cities are basically normal with no indications of radioactive contamination nearly 80 years later.
Does experience working with nuclear reactors and health physics qualify me? It's a bit out of date but certainly better than WIkipedia.
MUCH of what you are saying smacks of anti-Nuke hysteria. Those who dislike carbon fuels SHOULD embrace nuclear power but they usually do NOT. This is because (In My Bombastic Opinion) it is NOT about the environment or people's lives; it is INSTEAD about power, control, and the usual separation of the have's from the have-not's in a totalitarian system where upward mobility is heavily restricted for the average individual.
Flying on an airplane at 30,000 feet and getting an annual dental exam probably irradiates you MORE than any environmental effect from nuclear power plants, because the containment vessels have been carefully designed. I did a research paper on them once, back in 1979. The design included hurricane force winds flinging logs directly at them, and NOT having the inner wall crack from the impact.
it would depend on what is being calibrated. Let's say you have a specific secondary vibration limit (like a resonant harmonic) that cannot be exceeded. Measuring that secondary vibration would require a calibrated instrument. Or it could just be a total accelerometer signal level when vibration is induced. Anyway, THAT kind of thing.
(this based on my U.S, Navy nuclear power experience)
Once (nearly a decade ago) I took a 9 axis IMU and made it into a vibration sensor with an Arduino. It measured harmonics on a piece of material that was 'thumped' while weight was being applied as stress. The weight had the vibration sensor attached to it. This was a concept thought up by a materials guy who (as I recall) was working on his doctorate at the time.
"surely there have never been accidents because nuclear fuel got dropped accidentally?"
[and now I get to say it - "and don't call me Shirley" - heh]
Just do not accidentally form a supercritical mass when it lands... although without a casing it would go "ploothhh" instead of "boom" and maybe the containment vessel would keep it out of the surrounding environment, but that's similar to what SL-1 had happen (accidental supercriticality) and it's not good.
(yeah you would hope things were already designed to prevent such catastrophes, but when you compound procedural sloppiness and design issues you sometimes get catastrophes, RIGHT Three Mile Island?)
One possibility, just use a swapfile-backed memory map for your in-memory storage, one that is persistent (if necessary). On Linux, the 'mmap()' C lib function would do nicely. Then you'd just need some kind of utility to fix things or otherwise manage some settings and there ya have it.
"A hash table is a simple form of a key-value store but i wouldn't call it a type of database."
That is my preference, and I normally just pound out the code directly when it's needed (rather than shoe-horning in some 3rd party dependency).
A [scaled] CRC makes for a nice hash method. COPYPASTA a 20 line function and that part's done. Then you just need a simple structure array to store it in. A few more minutes and you've got a class or handful of simple management utility functions. Done. Serial lookup or hashed index (as needed).
I might eventually need W11 for doing my taxes "not on the cloud".
If that happens I'll get the cheapest pile of crap I can find that has 11 pre-installed. If I cancel my MSDN this time, it will pay for it 5 times over in 2 years.
I did zero windows development in the last year., and what I DID do (load something someone else did) I did with a DevStudio that runs on WIn7.
getting sick of Micros~1 and I'm too old to care any more.
[I should just stick with what I have, do not need TIFKAM or .Not or that other "App" thing]
If they kill Win32 API, I'm done with them forever.
min acceleration from 18k mph to 25k mph to get it out of earth orbit
or... de-orbit from 18k to about 16k and let the atmosphere do the rest (and humans have tons of experience doing precise de-orbit maneuvers)
probably cost way more to leave earth orbit, fuel + rockets + bigger engines etc.
Well, suppose Elon does a Falcon heavy but does NOT separate the outer boosters before it's in orbit... and the ENTIRE payload is a bunch of FUEL placed into orbit.
Then it is a matter of placing the 3 boosters (or maybe just one) into position, re-fueling them in space, and sending it all back the other way at the proper time.
SpaceX Falcon 9 boosters are (by definition) re-usable. It may be the least expensive option.
[re-fueling in space will eventually need doing, so why not use this time to develop a reliable process?]
Most likely it would work but of course we need data to prove it.
Just how hard would it be to make a 'habitat ring' that spins, for the ISS ? Gyro-stabilized and/or dual counter-rotation to overcome effects of friction and minimize the need for stabilizing thrusters...
Single-rotor helicopters need tail rotors. So a solution for friction (and rotation/mass changes) on rotating artificial gravity would need to be able to produce some kind of counter-torque.to stabilize it.
In My Bombastic Opinion any new battery tech needs to focus on something OTHER than lithium, particularly something that is CHEAP to build, yet still lightweight.
Aluminum battery tech may be the best alternative to something that is likely to form a bottleneck in the supply chain (i.e. Lithium batteries made by CCP). If they are SERIOUS, this is what they will do.
But, if they just want to suck away public funds to hire overpaid people and get ALL NEW equipment for the lab... don't expect ANYTHING revolutionary.
(and NO hiring CCP foreign nationals, either)
Other inexpensive and lightweight materials may be just as good (or better) than aluminum. Problems with lithium (easily catches fire under certain conditions) would be eliminated (not to mention the ENRICHING of the CCP as they have cornered the market on Lithium)
I'm not a fan of pure EV but HYBRID often makes sense as long as the battery does not make them cost prohibitive. Domestically produced inexpensive batteries using materials like Aluminum (which is cheap and available) would help a LOT. Aluminum batteries would also be good for phones, laptops, and so on. I'd just deal with the extra few ounces of weight, if any.
all snarky laughter aside, I ran into a problem with Rocky Linux's default config where they were (internally) using an RFC1918 address range that MATCHED THE NETWORK ADDRESS BLOCK BEING USED FOR THE ETHERNET. Needless to say, routing problems were UNSOLVABLE until I realized what they'd done, after which I did a grep on /etc for "192.168" and found where it was being assigned and then modified it to use something different... I forget what it was for, though. I told the Rocky devs on IRC about it.
"reserved XXX" that nobody knows about except the dev 'wot dun it'. yeah.
"So he admits to using code that he developed whilst working at a former employer for a later employer"
as long as you have permission, it's cool, but you want it in writing.
I have often done my own thing, then (after making it public) used parts of (or even all of) some my 'personal library' to speed up development. But I always put something in writing, and generally comment in the code "this portion of the code is from XXX github.com/whatever and is used by permission" etc. then written permission to the customer/boss, etc..
But yeah your code is OWNED by the company that pays you unless you get permission to use it.
[and yet EVERYONE has a library of past works, don't they? Just be careful using them...]
Excel, In My Bombastic Opinion (and its close relative, LibreOffice Calc) are VERY GOOD for certain *kinds* of analysis.
* I am too lazy to do calculus but I can copy a formula 1000 times with an incrementing 'x' and do an =sum() instead of a definite integral
* I want to chart some data really fast to see if I want to analyze it further
* I want to do :what if' analysis by coping formulas a bunch of times in cells instead of writing an algorithm
* I want to do some mass edits with tab delimited data and 'sed' + 'awk' would be too difficult
* I just want to collect a bunch of info that can be printed later (I do this for business expenses) and kept around forever
* I need to give a BOM to the boss and a spreadsheet lets me paste in URLs to a well known supplier (or download from their web interface if I create a BOM online) and the simple analysis would be total parts cost (from that supplier) as well as listing them all
* same spreadsheet is accepted by a board shop for assembly [so they can program their pick & place machines and source their own suppliers]
etc.
But yeah if I were serious about doing LOTS of math, I'd use a tool (or write one) that is more 'fit for purpose'
Here I am trying to remember all of the overhyped techno-buzzwords used in advertising, to try to ROOK people into buying into some "solution" that probably does not work, or at least not any BETTER than the old one.
So is a 5-tier solution better than a 3-tier? How about ONE HUNDRED TIERS! I'm left with nothing but tears...
Back in the 90's I worked on a program with a name that started with "AI". It used code generated by an algorithm that took a lot of parameters into consideration as part of its decision algorithm. By current standards it was primitive, but it did ok. Company ended getting purchased by a large company that was a customer, when it went started having financial problems. (I left before that)
Marketeers never cease to hype up 'snake oil' do they...
On a related note seems Warner signed a new "AI pop star", complete with a pretty decent single, and an "uncanny valley" video to go along with it:
Sometimes CUPS lags with 'bleeding edge' printer support. Solution: get a slightly older model, check for CUPS support beforehand. Save money. If it was bleeding edge 3 years ago, should be just fine now. Printer tech does not change THAT fast.
And if you check with the MFG they may have CUPS drivers, or if they support postscript even better!
I have an older 'all in one' print/scan/copy/fax that works well with CUPS and WIn 7. Yeah it is an HP but HPLIP is fine with me.
Had to use Win10nic this year to do taxes (did not want cloudy version), corporate AND personal.. Did it in a VM. Using 'windows update' print driver hung the driver, left paper stuck in printer with nothing printed on it EVERY! SINGLE! TIME!!!
I gave up, wrote to PDF (which TurboTax lets you do) and then used atril on FBSD to print stuff.
Maybe I can find a GENERIC postscript driver for Win1X that is compatible with CUPS and set up CUPS for internet printing - anyone?
I was thinking that this is Micros~1's way of "picking winners and losers".
You want YOUR device to run on Windows, right? Pay UP or GET LOST! *WE* control *EVERYTHING* now!!!
3rd party drivers and the DDK were one of the BIGGEST REASONS windows became "a thing". This new "One OS to rule them all" posture from the latest generation of "It's OUR turn now" [probably woke] 'engineers' is one of the biggest "READY, *FIRE*, AIM" "Shoot your own foot" maneuvers from these "less than highly intelligent" people YET...
One thing I have done in the past (somewhat necessary if chrome gets used when doing an embedded UI in kiosk mode) is to find out which files in Chrome's hierarchy can be deleted without deleting ALL of the personalized settings, and then DELETE THEM with a script on exit, or before Chrome starts.
That list seems to change a bit with newer versions, though...
If chrome has not yet got one, it needs an "erase history on exit" feature. Firefox has this (or did last I checked).
Chrome is often brain-damaged and even caches style sheets when you are trying to work on them,. Painful.
At some point the 'M' for 'MAP' will be added to the LGB alphabet soup (if things continue on the current path), much to the chagrin and outrage of the 'LGB' portion (who just want to be left alone to live their lives, consenting adults etc,). The radicalized agenda has driven things WAY past common sense, long ago, and everyone who disagrees with this new added letter (or is outraged by it) will be labeled 'bigot' or some kind of '-phobe'.
(I'm sure pointing this out is potentially offensive to many, but so is having an agenda crammed at us, so SOMEONE had to say what many are thinking, and take the arrows).
That being said, the "moral outrage" crowd that would play "THOUGHT POLICE" with art that does NOT exploit actual children may actually end up signing onto the radicalized agenda behind changing the word 'pedophile' to 'MAP'. Do NOT doubt me! (Rush Limbaugh used to say things about this topic a LOT, particularly regarding organizations like NAMBLA, who have been around for a LONG time)
(sad face because nobody really wants the 'M' for MAP in there)
To summarize, exploiting actual children needs to be punished with extreme prejudice to the fullest extent of the law.
Prosecution for anything else that does NOT exploit an actual child is essentially "THOUGHT POLICE" and must NEVER happen, regardless of any professed "moral outrage"
That's my take on it, at any rate.
[environmentalist wackos] "questioning the decision-making process of the FAA in granting SpaceX a license to launch in the first place."
I wonder how many of them use things like cell phones, internet, and satellite TV? You know, things that (often) need A ROCKET to put a mini-moon into orbit.
Vexatious SLAPP sueballs - there needs to be a SERIOUS PUNISHMENT for doing that, but it seems there never is...
(it's an example of 'Tyranny of the MINORITY')
"Who owns any product these days?"
* TV deliberately "not smart" and not connected to intarwebs (cable box notwithstanding)
* Blu Ray NOT connected to intarwebs either
* Computers built by me running FBSD and Linux except that one that has windows 7 on it (reconditioned Lenovo, from which i do NOT web surf)
* Car is 20 years old. I keep fixing stuff when it breaks.
* Fridge, clothes washer, GAS clothes dryer, microwave oven are well over 20 years old (old school stuff) and still work.
This old stuff still works just fine. "Upgrades" are *HIGHLY OVERRATED*
If you put a note-sized chunk of aluminum foil in your wallet, it will probably disrupt any attempts at snooping your data via RFID tech with a scanner, attempting to read your cards without your knowledge (including driver's licenses with chips in them). It was known long ago that such a scanner in proximity to you COULD read the chips that make "Tap" work at the point of sale. Credit card companies do not want this well known. But the simple hack of a mini-Faraday-cage (aluminum foil) can "foil" the attempt.
This was brought to my attention YEARS ago in a post made by one of the Myth Busters (Adam Savage I think), who said that they WANTED to include this on the show (being able to scan people walking around in public) but were PREVENTED from doing so by management under influence of banks, etc..
Agreed on the use of cash and coin - anonymity if no 'store card' is involved.
Unfortunately there are too many attempts being made to go to "digital currency".
I often prefer paper or plastic+paper with numbers, letters, and pictures of past/present leaders, monarchs, etc. on them. And if this gets out of hand it may be the ONLY alternative to being snooped on.
/me thinks of ways to turn a car into a Faraday cage, disconnect antennas, etc.
Like with EV mandates, VIOLATING PRIVACY with new vehicles can only lead to ONE THING:
Just like in Cuba, car owners will JUST FIX UP THE OLD ONES!!! To *HELL* with "buying new" when the OLD one is PERFECTLY FIXABLE.
Ever look at RESALE VALUE of an EV? HA HA HA HA (that replacement battery costs more than the car is worth). Those EVs will be like OLD CELL PHONES at some point.
And even if it DOES run on gasoline or diesel, do people REALLY want to give up personal privacy JUST TO GO TO WORK EVERY DAY?
Meanwhile a 20 or 30 or even 40 year old car or truck will KEEP ITS VALUE, especially with new seats and drive train,. This is a good opportunity for mechanics, welders, and people good at fixin' up the car interior. And don't forget paint.
This is how the automobile market dies... or GETS DELIBERATELY KILLED!!!
semi-related - I keep getting old XBox 360's (and fixing what I can) to play those older games I like to play that I spent REAL MONEY on. I refuse to get an XBox One though a new Playstation might be in order at some point. The point is, Micros~1's trend towards "requiring online presence" and "cloudiness" and BLATANT SNOOPING tells me I need to unplug from the 'net. SIMILARLY, *NEW* *CARS*.. I shall keep my old one as long as I can and buy used when I must. CARBON BURNERS ONLY!
That pretty much sums it up.
It still takes a lot of money to make a movie, even a crappy (or woke) movie, with a high likelihood of it losing money overall when box office ticket sales circle the drain.
Hollyweird wants to do it cheaper, using robots. Actors want to continue getting prohibitively expensive salaries.
I think the robots will win. THEN Hollyweird can still excrete lheir worthless woke / crap movies but at a lower overall cost.
(the actual problem is that Hollyweird forgot how to make a movie worth seeing in the theater, and how to sufficiently market it so that people do not wait for the disk)
It is highly likely that Huawei's innovation comes from Taiwan, not 'CCP China'
I've worked with engineers from Taiwan. They are very much like the engineers I've worked with in the USA and UK as far as skill, competency, and quality go [from my experience anyway].
Taiwan != China. It's the COMMUNISM that makes the difference, not so much who, or where, or who it is that is signing the checks.
For now, at least, Taiwan is "safe"...
"I'm not sure whether it is hubris, racial stereotyping or a lack of understanding of how technology develops that leads politicians to think that China will have trouble replacing the technology they are blocked from buying."
It's mostly HUBRIS.
China is a country, not a race, and it is COMMUNISM that stifles innovation (it is VERY hard to innovate when thinking outside of the box hurts your social credit score or gets you 'disappeared' which makes it hard for a U.S. company doing OEM mfg from 'CCP China' to deal with the engineers in 'CCP China' when trying to get problems fixed - yes, I have had to deal with that - in ONE case they first DENIED a problem existed, then fixed it a DIFFERENT way than what was suggested as a quick stopgap, months later, without saying anything).
But at least HALF of the politicians have NEVER INNOVATED. King Bidas, the doddering fool currently occupying the White House [for whom everything he touches turns to CRAP], has NEVER HAD A REAL JOB, particularly one where you have to make/build or design/invent things. Nor have his puppet masters, more than likely [lib-T think tank nor lefty college professor notwithstanding - plenty of THOSE kinds of people in Maryland, just north of D.C. - is NOT a REAL job].
If there is an actual GOAL here, it is to create a superficial APPEARANCE of a paper tiger, targeted at those who cast ballots out of *FEEL* instead of intelligence, while making corrupt deals behind the scenes. *COUGH*HUNTER*COUGH*
Really smart trade agreements should be made by those who understand business, NOT politics, and do not DIRECTLY PROFIT FROM THEM [through multiple shell companies as one example].
"the cloud habitat for Anaconda's Python will presumably be more secure than having Excel users downloading libraries on their own. Having anticipated concerns about enabling yet another attack vector in Excel, Microsoft has preemptively declared that its snake has been tamed.'
HA HA HA HA (oh wait, they're serious; let me laugh even HARDER!)
What part of THIS is 'more secure' ?
* Data stored in the cloud where governments and evil hackers can view it
* relying on "their server" performance including the pipeline to/from it
* DDoS, downtimes, network problems, MItM and DNS cracks, etc. NEVER HAPPEN, right?
More exist but another post near the top hit on the best ones
as long as Xorg remains the default desktop engine (or at least easy to select during install), there won't need to be any more forks.
(Wayland cultists can have their systemd and other Poettering clusterer-blanks along with Wayland in other distros)
in my last Devuan install (chimera) I added X and mate in a separate step and it set up as a console login using 'startx', rather than booting into a GUI. Much better I say.
Zero.
Wayland is a complete waste of developer energy and effort. Extending Xorg and providing good quality hardware support, especially open source hardware acceleration, and avoiding GTK past version 3, should be their #1 priority, and NOT time-wasting on what could easily be described as "The 'Supriority by Arthur C. Clarke' moment" also known as Wayland.
export DISPLAY=othermachine:0.0
This is the #1 BEST feature of Xorg, especially for embedded development.
[I go out of my way to ensure Wayland does NOT get installed]
You're welcome.
"Also, the blades of wind turbines are not biodegradable, and is also a huge issue."
THIS PART, at least, is true.
the whole "Carbon Footprint" thing is an anti-science hoax anyway. Basic chemistry and physics disproves their nonsense. Human nature and the seeking of power over others by elitists explains it.
