Lockdown has certainly prompted a boom in bike sales
Just what our essential HGV drivers need, lycra clad families wondering all over the road - as they livestream on Zoom. It's bad enough for our HGV drivers having to remember to use hand sanitiser once a day, but avoiding a MAMIL who last rode a bike 30 years ago, is taking social distancing too far! I'm writing to Boris. Hang on, that MAMIL is Boris!

If you think that's bad, post-Covid Japanese anime (animation) movies will now be a static image of a character just blinking, for 20 minutes. Which isn't any different to pre-Covid come to think of it.

We may have to get used to NOT binge watching box sets, just to make the episodes last to Christmas. Sorry Netflix.

There's ~60 years of TV shows out there in the world, most of which any one of us have likely never seen before. I still haven't seen any shows made within about the last 3-4 years.

Cycling isn't that dangerous, it's mixing bikes with motor vehicles which is the problem. The government have said there will be more cycle tracks and some roads closed to motor vehicles, so more people can cycle safely.

I hope they stick to this and do it properly. One of the problems I've had is some cycle lanes are narrow strips along the side of the road and are often more dangerous to use, than cycling on the road. The trouble is the cycle lane is on the left hand side of the road, meaning cyclists will undertake slow moving traffic, for those in other counties we drive on the left here, causing accidents when motorists have to turn left and don't see the cyclist because they're in their blind spot. I just cycle along the middle of the road, when the traffic is slowly moving and nothing is coming the other direction, or the road is wide enough to safely do so.

Cyclists should be separated from motor vehicles, as much as possible and ideally kept away from pedestrians: I've had a near miss with pedestrians on a cycle track because it's dark, windy and pouring with rain and they're dressed in black. I didn't hit them because I had the sense to have nice, bright lights. Some idiots cycle in the dark, with no lights, dressed in black. What's more silly is there's enough room to make the path wider and put a fence in the middle to separate the pedestrians and cyclists.

@Zero999: thanks for the pointer to the Kona. That's a pretty nice bike for the money. May look in that direction  :-+.

@Syntax Error: Better a MAMIL than a Covid statistic  :-DD

Anyway on topic again for a minute. OpenReach are digging up the bloody road again today, on a Sunday. Third time this year now. There is nothing more anxiety-building at this point in time than an a couple of OR vans parked up the road when you're a home worker. For the non UK residents, they are the guys here who manage the "last mile" from the exchange to our houses. POTS, ADSL, Copper, fibre, the lot. They consist of a few thoroughly competent individuals and an army of morlocks. A few years back I had a line fault (noise) and the guy came out and buggered the entire line. Said he'd just go back to the van and be back in a minute and drove off.  :palm: :palm: :palm:

Talking about the impact of the virus on business - according to the BBC:
"Lockdown has certainly prompted a boom in bike sales.

I went to several bikes shops the other weekend looking for a new bike for Sagan, lines were out onto the street and they were turning away all bike servicing customers. One store hired a new employee just to answer the phone full time, and she couldn't even keep up with the volume. One big chain store has suspended all inter-store deliveries and on-line orders, they just couldn't keep up.

A year from now I bet you'll be able to find a smoking deal on any number of lightly used bikes. I'd wager at least 30% of the ones being bought right now will be ridden a handful of times and then parked in the garage.

I was looking for a new 2nd hand bike recently, but I think I'll wait...  ;D

It's been quite interesting to see how different bike stores are dealing with being open for business.

One major chain's web site says "You will not be allowed to enter the store but our colleagues will be on hand to pick products for you". Similarly, another says "Please stay within the marked customer area. Unfortunatly, access to the wider shopfloor is not permitted. Let a member of the team know which items you require and we will locate them for you".

Both mention that they're really only open to provide essential services to keep key workers moving, which may be absolutely true, or may be a PR statement to try and deflect criticism over whether or not they "should" be open at all. Either way, I took the hint, and didn't even bother visiting either.

Independent stores were operating much closer to business as usual. Clearly there's a major difference between the answers to "how can we open for business" vs "how can we ask our staff to open for business".

All the independent stores were all limiting the number of customers in store at any given time, so there was some queueing outside, but all the usual services were on offer - advice, fitting, test rides and so on. Both staff and customers are still clearly trying to learn and adapt to what the "new normal" will be... where to stand, can I do 'X' from 2m away, is it OK to touch this - and there's no consensus just yet on what constitutes "safe enough".

Here in England, having observed the lack of self discipline on display this last weekend, I would say the general public has taken the goverment's "unlimited exercise" directive as meaning, carry on as if nothing had ever happened.

Social distance, follow the arrows, don't crowd, you wot???

I would not be surprised if the R0 number is 1.5 by Friday.

https://www.npr.org/sections/coronavirus-live-updates/2020/05/16/857379338/5-uss-roosevelt-sailors-test-positive-for-covid-19-again

Quote
The U.S. Navy says 13 sailors from the USS Theodore Roosevelt who had apparently recovered from the coronavirus and had received negative test results have now tested positive for a second time.

In a statement released earlier on Saturday when five sailors were found to have retested positive, the Navy said the sailors had "met rigorous recovery criteria, exceeding CDC guidelines," including testing negative for the virus at least twice, but have now retested positive. The statement said the sailors had been monitoring their health and adhered to social-distancing protocols while on board the Roosevelt, which has been docked in Guam following an outbreak infecting hundreds of crew members.

"These five Sailors developed influenza-like illness symptoms and did the right thing reporting to medical for evaluation," the statement said.

At first glance, this seems to be saying that having had CV19 does not make one immune. Unless there's some other explanation.

It is possible to get tested positive again if you are subjected to enough virus particles to overwhelm the immune system or the immune system is in the process of fighting it off. Also possible to be tested positive again if it's a PCR test and is contaminated or you have bits of dead non-viable virus fragments all over you.

WOW!!!!.... Now I really know what a 'TROLL' is.

Says nothing positive in life, knocks & abuses everyone & everything, solves nothing with their 'views', and contributes nothing except rants of self appraisal and bitterness. 

Why are they so ANGRY in 'life' ??  :scared:







Thanks mate, such comment from concerned fellow aussies is always appreciated, and helpful to all our patriots in these confusing trying times  :clap: 


I was trying my best to inform the very learned and helpful folks at this electronics forum, they are being duped by millions of networking professionals
spread across all the nations, especially now that communication is easy via international mobile phone coverage, skype, zoom and the like,
with full financial and decisive control over all the information outlets, news media carnivals etc. > welcome to verify that for yourselves if that smells like conspiracy instead of 'investment'

I wrongly assumed many here have the knack to smell the obvious corona bandwagon convid-19 BS, and investigate it thoroughly from all the angles,
especially with all the expertise demonstrated at other thread posts at this forum,
going to town on conspiracy theories, flat earthers, startup project money grabbing scams,
and awesome knowledge of manufacturers original parts and spotting fakes easily etc etc etc 

It appears I grossly misjudged and assumed electronics enthusiasts with good diagnostic ability in general,
also had a fair level of street smarts too, to suspect foul play going on, or smell the odor of a good con going down.

I sincerely apologize if my barn door kicking style has upset any members and put me on the troll radar,
as well as brought me to the attention of any closet censor group, making me a target to be ridiculed, ignored and ousted.

If that is the game being played, so be it,
I've watched it happen to others that cared enough to question the international criminal syndicate behavior running rampant again.
this time testing the waters to the extreme, for whatever they have planned next,
which I can guarantee them will be uncontested and unquestioned, and an easy gig/s to pull off, time and time again 

Have a good laugh at this comment, troll call or twist it about as before, but please remember who's at home going broke and or frustrated/depressed/bored, or soon will be,
stressing if/when the cushy 'Working From Home' honeymoon period dries up,

questioning by now (SURELY!?) what's really going on, and for how long,
if it's being handled correctly and not now a newly established  'industry'
dragging this out to squeeze a bit more juice..

and spare some kind thoughts who's still making and counting serious money during this ordeal, with no gloves or mask on,
with the ability to buy mortgaged homes, business properties, assets and freeholds for a song soon

Maybe they'll toss some casual work in the bankrupt business once proudly owned,
if you work cheap enough  :popcorn:

Dear Electro Detective.  Thank you for your reply. Let's be honest, (including myself!), unless 'we' (forum people) have direct and faultless understandings of each other here, the fact remains that 'we' don't really 'know' each other from the Proverbial "Bar-Of-Soap". We can ONLY assume things, from what they 'write'.

'I' myself, have been judged over the years... And that's OK!! Not everyone understands where I'm 'Coming From'...
I think that my 'Dig' stemmed from the fact that I'm an 'Aussie' too, and don't want the 'world' to judge us negatively, or place us all in the proverbial "Same-Basket"...   It just seems that, (EVEN in your last reply!) that you are repeatedly so 'negative' about all in general ?
At times like this, we all need to work together, and not to alienate everyone in a power struggle?? Be peaceful man...

Yes, I guess the same applies to almost any other virus, actually.

So being tested positive "again" doesn't mean you are not immune to it.
If you are "immune" to some pathogen, that means your immune system is able to fight it effectively - which is going to be detectable while it's fighting, or am I missing anything?

Its rare but it has happened with COVID-19, and they still dont know why it seems more common in some places than others.
 I am pretty certain they don't know why.

Some viruses never go away. You immune system usually keeps them in check, but if you get an illness that requires you take immunosuppressant drugs or there are environmental causes too, then you become more suceptible to those viruses or if you already have them they may reactivate.

Just because someone tests positive, it doesn't mean they're infectious. As he said, the test is sensitive enough to pick up old, inactive virus particles tucked away in the tissues.

Tests can also come back false negative, but as long as that's rare enough, it will have minimal impact on mitigating the spread.

I think we as engineers like to rely on certainties, but in medicine they are rarely any. In a large scale system such as a pandemic, something only needs to work most of the time, in order for it to be effective.

Thought Emporium has an interesting video on the PCR variant tests.  Basically it's a live stream where he actually creates a PCR test for Speckled tobacoo virus to find out if his plants have it.  It's very obvious it would pick up broken shards of viral RNA/DNA by how the tests work.  It only takes 1 or 2 particles containing the primer sequence to exist in the sample and the enzyme(?) will copy that sequence millions of times any amplify it.  So the test only tells you the particular sequence was present, usually only a small section, enough to uniquely identify the virus.  It cannot tell you if the piece came from a complete RNA/DNA viral component or from fragment.  Nor can it tell you how much of that RNA/DNA was in the sample.

PCR tests can tell how much is there by a process of progressive dilution. They describe it in terms of "titers" (as in titration). If SARS-CoV-2 RNA titers are described as high that means that the presence of the virus still registered positive through many successive dilutions (of the substance under test). However, if a test is in short supply, it stands to reason that instead of doing multiple tests to determine stength of a virus, they might simply go for a positive or negative, because determining the titer is too resource intensive for an emergency situation.

On immunity from CovId after infection.  Will that stop you getting infected, forever, in all circumstances?  I'd doubt it.  It's not a playground shield, "But I have shield!"  Nahnahnahnah!".   If you have a measles vaccine are you completely immune to measles?  No.  If you have been infected, recovered and now show as having antibodies, then you're not immortal, and possibly not even completely immune, but you certainly have much more than the rest of us do in real terms.

The number of coronavirus infections we receive each year is very probably extremely high.  Considering most of them are common colds.  It's the three deadlier ones we need to watch out for now.

Following Trump and his followers I have come to the conclusion we need a solution for the majority of people, so I came up with this:

Sodium Hydroxide enema.

It will regulate your sodium levels.  It will regulate your cell oxygen levels and of course it will hydrate you.

Look at it this way, you don't want low sodium, it could effect your immune system's response to the virus.
See:
http://chemocare.com/chemotherapy/side-effects/hyponatremia-low-sodium.aspx?fbclid=IwAR1Tl5_ibz67329hdy3DxwjWAIpuWFc4wjBdvoc0OoPhCCmMwdYAR_EzEQg

Nor do you want low oxygen, it could lower your immune system and cause you to get CovId19!:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4064601/?fbclid=IwAR3pYcYFeY_O1eZNWgjmmJd4MHSTWPSwkWOv-CtMmI1xP8ru0aN5R7KT2Bg

And you really, don't want to become dehydrated as it will effect your whole bodies response to pathogens.
https://www.nhs.uk/conditions/dehydration/?fbclid=IwAR2GlFwL69uRWwryHV7pd69ripPlN17pVnEIlJL_AFZzolEOPF-bTXl7Kdk

So.  Sodium Hydroxide up the bum is the best way to protect yourself.

Note:
Only works if you do it to yourself.
Does not work on children.
Does not work on those really smart people you know.  Yes, them.

For quantitative PCR, you only need to perform titration to create a calibration curve.

I was SURPRISED the other day on TV. (Can't remember what Country...)   ???
They were showing the 'Flashing' of the insides of Trains/Buses? with high intensity UltraViolet.
I 'assume' this intensity meant that no people were in them at the time?
It wasn't a continuous 'illumination', but was like a set number of very high power flashes
from a Camera Flash, but of a frequency that guarantees killing the Virus, from everywhere
inside the cabins, without the need for physical cleaning of surfaces!!  Looks good, if it works..  8)
