gHosts··on Covid-19: politicisation, “corruption,” and suppression of science
Bizarrely enough I found a tweet by a rabid right winger and covid denier that linked this BMJ article as proof that covid was a left wing plandemic conspiracy.....

The twit obviously didn't read more than the headline.

Probably hadn't read more than the headline of anything actually.

gHosts··on John Gray: 'What can we learn from cats? Don't live in an imagined future'
Bollocks.

My cats regularly imagine a future in which I'm going towards the fridge to provide them with food......

...when the reality is I'm going elsewhere and just going to trip over them.

gHosts··on Tom Lehrer releases song lyrics to public domain
Reminds me of The Good Old Bad Old Days of the South African arms industry.....

...built entirely to circumvent sanctions and fight "Die Swart Gevaar/Rooi Gevaar"... ("Black Danger" / "Red (Communist) Danger")

When the changes came they continued on without missing a beat except their number one problem now was to convince someone to continue paying them to carry on making munitions.

gHosts··on 'Near extinction' of influenza in NZ as numbers drop due to lockdown
We are, and continue to be, a major exporter of food.
gHosts··on 'Near extinction' of influenza in NZ as numbers drop due to lockdown
> if you close your borders, don't produce or import anything globally.

We're producing and exporting and importing just fine thank you.

Borders are closed to casual visitors, not goods.

Yup, that can (and just has) create opportunities for the virus to enter.

But that is a risk that can and is being managed.

gHosts··on 'Near extinction' of influenza in NZ as numbers drop due to lockdown
Actually, reality has fine print....

Instead of overseas visitors spending in NZ and rich NZ'ers spending their tourist dollars overseas .... the richer NZ'ers are spending locally.

Turns out not as different as the doomsayers predicted.

gHosts··on Do We Live in a Simulation? Chances Are about 50–50
In the category of bright guy that believes this, and has some pretty concrete ideas on how it would work, but admittedly is pretty "Out There"...

gHosts··on Wim Hof’s teachings about breath work and the health benefits of cold plunges
Compared to what?

Do you have an evil twin that doesn't have bruxism?

gHosts··on Wim Hof’s teachings about breath work and the health benefits of cold plunges
Dunno whether it does, but if it does, I bet South Africa Biltong chewers must have strong masculine square jaws fit to bite off any competition then.'

Hmmmm. Biltong.

I'm drooling.

gHosts··on Linux Kernel Developers Fed Up with Ridiculous Bugs in Systemd
Very early April 2014...
gHosts··on That coworker who never stops refactoring
The technical term for that is "a Lava Flow".

The code melts and changes for awhile... and then congeals into unchanging rock again.

gHosts··on Researchers “Translate” Bat Talk (2016)
I can just imagine the bat cave now..., "ROOOOBBIN!! You haven't taken out the rubbish!"

"Nah! It was your turn you big bully!"

gHosts··on VCs Are Destructive Predators
Now saute the VC in butter....

Bon Appetit.

gHosts··on VCs Are Destructive Predators
I once had a chat with a VC bag man...

He said their policy was to invest in a 100 startups in the hope that one would go viral.

The sooner the other 99 died and stopped bleeding the happier they were.

Go big or die soon was their policy.

If the 1 went viral, they'd make back all and way more than they lost on the 99.

The fact that 99 founders were broke and broken didn't bother them at all.

gHosts··on VCs Are Destructive Predators
The solution is butter, apple cider vinegar and salt.
gHosts··on Seven 'no log' VPN providers accused of leaking 2TB of user data
As Bruce Schneier says.... Data is the toxic waste of the modern era... you just know sooner or later it's going to leak.

Don't collect it if you don't need it. Destroy it as soon as possible if you do.

gHosts··on Schools Beat Earlier Plagues With Outdoor Classes
Conversely, their parents and grand parents get infected by the little plague carriers returning from the plague pit and general viral exchange facility that is school.

And the grand parents and obese parents are vulnerable as all merry hell.

gHosts··on To Delay Death, Lift Weights
Correlation is not causation.
gHosts··on How objectivity in journalism became a matter of opinion
Supposedly https://www.britishpathe.com/ was an icon of journalistic objectivity in it's day.

Today it looks like an icon of British Imperialist jingoism.

gHosts··on To Delay Death, Lift Weights
> confirming the inverse relationship between strength and all cause mortality

Ahh, but which way does the relationship go..?

Unsurprisingly if I'm dying of something really serious and lying in bed sick as a dog.....

...I lose muscle mass.

gHosts··on On Behalf of Environmentalists, I Apologize for the Climate Scare
I call that one "Proof by Reference to Pay Walled Article".

That article could say absolutely anything for all I can see....

gHosts··on The global fertility rate is falling
Anybody look at that graph and say...

WTF?! The data says nothing like what the headline says!

Yes, the projection goes down sharply... but the best estimator of tomorrow is yesterday, and the last few years of data are saying nothing like what the projection is showing!

gHosts··on On Behalf of Environmentalists, I Apologize for the Climate Scare
There are quite a few remnants of the Whaling industry around NZ... it's clear that one of the major reasons was they were so damn near extinct it wasn't anywhere close to energy profitable to hunt them anymore.

For some phantasmagorical stubborn up yours world, various nations continue to hunt them. Sea shepherds have been fighting that sort of crassness.

gHosts··on On Behalf of Environmentalists, I Apologize for the Climate Scare
I tried to find the source for the AOC quote.... I want (as always, whether Trump or AOC, to see the exact quote in context) and encountered a interesting new form of obfuscation... Proof by reference to a 4 hours long video!
gHosts··on Why do so few people major in computer science? (2017)
Because there are such perverse incentives in Academia that what they do and teach have no relevance to anybody.

eg. There was a major linux conference at the local university.... Full of cutting edge real world OS / HW stuff.

The CS department didn't bother to attend.

gHosts··on Lossless compression of English messages using GPT-2
For more fun enter "I am going to work outside today" compress, delete the second character and decompress, the result is... "I know what you're thinking –"
gHosts··on Embedded Rules of Thumb (2018)
> Programs without documentation have no value.

Counterpoint.

Your users won't read the documentation. Get used to it.

Odds on your developers won't either.

Take care when you do read the documentation, it's probably out of date and / or wrong.

gHosts··on Embedded Rules of Thumb (2018)
If your device doesn't change the way your customer does business, why bother?

Every truly successful device will be used for purposes you didn't dream of when you first created it.

gHosts··on Embedded Rules of Thumb (2018)
Had a GPS that started jabbering crap when it got cold.... showed up as system dying because it was being flooded with events, ie. Some other task died because it wasn't getting enough cpu time.
gHosts··on Embedded Rules of Thumb (2018)
Try this as a way of thinking about it....

ISR's are random events that preempt your scheduler.

Deferred Service Routines run in the same thread as your scheduler.

It's excruciatingly hard to write (correct) code that can be interrupted and have it's internals monkeyed with at any clock cycle.

Thus the ISR/DSR handoff is a way of sequencing events into a manner the scheduler can handle sanely.

Most ISR's are written to be preemptible, it ack the interrupt and enable interrupts. Thus the chance of losing an event is very small.

The larger your isr the more you're into the realm of "excruciatingly hard to write (correct) code".

Your scheduler may be very simple... eg. only one thread as you described above, but my point applies.
