and tell us how many Nobel prizes have been given out since the START of

Who is this "us"? Are there more than one of you?

Come on, you can do it.


Why? Are you telling use that the only intelligent people are Nobel
Prize winners?


I think silly lttle tommy is trying to emulate Linus Pauling who won a
Nobel for his work in physics, but is now remembered solely for his
vitamin C scam. silly little tommy has the second bit, but not a hoe inthe
first.


Minor correction. His 1954 Nobel Prize was in Chemistry. In 1962, he
received the Nobel Peace Prize:
https://en.wikipedia.org/wiki/Linus_Pauling

When I was young and stupid, I fell for the vitamin C scam. Every
time I felt like I might be catching a cold, I would take vitamin C in
the amount and manner prescribed by Pauling in one of his book. Oddly,
it worked for me fairly well at preventing or delaying a cold. I was
rather surprised when the Mayo Clinic ran trials and declared it
ineffective. Of course, they were testing it as a cure for cancer,
not a cold. Your mileage might vary.

Perhaps Tom was thinking of the Ig Nobel Award winners? The winners
really are quite intelligent in all areas except for their selection
of research projects:

Mine have broken twice in the past 2 years right at about 6 months. The cable ends fray and lucky me it is flat in Illinois and I just ride home and put on a new cable. I change the last one that snapped in July 2020 so about a month ago instead of waiting for the cable to snap I just put a new one on. It is always the rear derailleur don't use the front much. Well sure enough the old cable looked fine when I pulled it out no fraying but I put a new cable one. Really a minor price to pay for not worry as much about snapping them on a ride. Actually I am pretty lucky I get 3-4000 miles before they snap or need to be change. No not going to Di2 my 6800 shifts smooth and silent.

I have no understanding of how you can do this. I did break an old steel cable that the Chinese were selling, or rather that a local was stocking and selling out of his garage. But I have never broken a single stainless cable and I have used some pretty cheap ones. I prefer the top end Campy cables and have never even come close to breaking one AFTER it was installed. As I was recovering my memories and some manual dexterity I did break some cables while installing them. But that was long ago and far away.

Well it is at the end in the shifter so it frays from the anchor point in the cable. Not like the cable just snaps into 2 separate pieces. If fact the cable really does not break it just pulls apart in the shifter and then you have to fish the parts out and make sure leave nothing behind. Shimano on the new stuff now has a part on the shifter to remove at space to get the cable head out. I have heard on earlier stuff sometimes they got stuck in and then you had to replace the shifter. There is even some place they have a way t drill through the shifter to get the cable head to spare the shifter.

But frankly if you want to know the truth on why it happens to me is because of all the power I produce in the hands on the shifter. I mean I can drop some serious power numbers up there when I take the swipe 🤣
Deacon Mark

Shimano never used this design in which both cables come out under the tape.. This is a fairly new design and it is a funny design in which you poke the cable through from one side, remove a compartment cover and push the cable at a 90 degree angle up though a small passageway. I had misgivings about it when I saw it but it appeared to work fine on my 105 stuff on a cyclocross bike. I would have used what I think is called an Archimedes wheel-like mechanism.

You have already told us that you only rarely ride a bicycle anymore
That's mostly correct. What I actually said before you twisted the
meaning is that I am no longer able to properly ride a bicycle. If
you want, I can explain the medical problem that created this
situation. I still have two bicycles, which I occasionally ride short
distances.
so perhaps you might want to explain what you're even doing on this group?
Perhaps? That suggests that I can perhaps choose not to explain. So,
I won't explain because you don't need to know and I don't feel like
justifying my presence.

However, I can offer you a fair trade. I'll answer your question if
you explain why you reply to every single thread, statement, question,
and comment in R.B.T. I believe that I understand the motivations for
your other odd habits, but the need to add your uninformed and
unsubstantiated opinion to every discussion has me mystified. Why?

You probably don't trust me to provide a genuine answer to your
question, so I'll go first if you agree to answer my question in a
similar manner. Deal?
You have also chosen not to explain what in the hell you know about digital engineering, embedded systems and programming so that you could explain what I didn't know. Instead like an English teacher you've chosen to pick my resume apart for its spelling errors and not the thousands of human lives I've saved.

You are the one that decided to insert yourself into this discussion after that moron Frank chose to tell everyone I was lying about hitting a tree branch because he could find street pictures of that area only 5 years old. So don't pretend that you have ever had any effect on the world around you because I've spent my life doing just that whether it was volunteering for the Air Force or being part of the construction of the world's largest time sharing computer of the time. The job I had before the concussion was designing and programming devices for the detection and treatment of Cancer. Did your radios help that? Half of this scientific world has been changed by the things I have done. And I have a right to be proud of that.

Of course we could always go with Jay's idea that if I designed anything of value I would have a patent on it. Elon Musk doesn't have any patents but I should. Charley Button owns no patents of his intercoms and radios but I should. I have never even heard of a development engineer owning a patent but dollars to dimes Jay could find one.

If you want to be a part of a discussion talk about things you know and not for the reason that you want to complain about how badly I treat you after you started it.
An accurate quote would be appreciated. What I said is that IF you had any significant inventions, your name would be in the USPTO as a an inventor if not as a patent assignee/owner. Elon Musk at the USPTO: https://tinyurl.com/ze3jzzcw At least he is mentioned -- and his company owns many patents: https://tinyurl.com/5fjj8kh5

Elon is mentioned in this patent which we should apply to you: 10,963,467 "Determining whether a user in a social network is an authority on a topic." You should go read that. Here is the abstract:

"A method involving obtaining a first plurality of topic groups (TGs), each having a membership of accounts, identifying a first plurality of accounts as authorities for an expertise topic, obtaining a second plurality of TGs with a number of accounts as members, wherein the first plurality of TGs comprises the second plurality of TGs, identifying a first frequent account which is a member in at least one of the second plurality of TGs, adding the first frequent account to the authorities of the expertise topic to obtain a second plurality of accounts as the authorities of the expertise topic, determining a third plurality of TGs in which a second number of accounts from the second plurality of accounts are members, determining that another frequent account is a member in one of the third plurality of TGs, and obtaining a ranking of accounts that are an authority on the expertise topic."

Got it?

By the way, there is nothing about your accomplishments anywhere except in your LinkedIn page. If you invented half of the scientific world, one would expect to see you mentioned somewhere, if not the USPTO. Maybe a professional journal, association news letter, company press release, police blotter -- well, you did make the police blotter.

-- Jay Beattie.

Your world must certainly be small if what I did seems to you to be the half of the scientific world. Tell us, what is it like to live on a small planet? Do they have mostly peaceful protests that burn a town down?


Folks, I think we have to seriously consider the possibility that Tom is
well into dementia. It's sad, and I'm not joking.

In his post about 33 lines above he said "Half of this scientific world
has been changed by the things I have done." But at the end of the
quoted material just above he said "Your world must certainly be small
if what I did seems to you to be the half of the scientific world."

So he can't remember what he very recently said. This example is far
from unique.

I don't know how to deal with someone whose mind is slipping and who
spouts nonsense. I've read that with a family member, one tactic is to
say "Yes, and... " then pivot the conversation to something pleasant and
distracting. Pretend to agree, then deflect. But I can't see that
working here.

Is there a psychologist or therapist in the audience? Again, I'm serious.


Perhaps Tommy has read the same suggestion that you have about pivot
the conversation into something else... he does it all the time.

I tacked a bit, got home and then jumped on the Di2 disc Synapse and

The discs, BTW, don't drag at all. Thank Buddha for that reliable

The good thing about the latest Ultegra levers is that there is a
trap door under the lever body, and you can remove one screw, take
out the door and grab the broken cable and end. No more fishing it
out of the lever. This is the second time in 20 years on STI that
I've broken a cable. Before that I broke a friction bar-end cable in
the middle of a tour. I had a spare.


I guess when you've been riding the Di2 setup for the same time &
distance you'll be able to make a more reasonable comparison.

I'm still waiting to break a cable after more than 30 years of using
cable actuated gears and brakes.

I tend to have to replace as the cable gets sticky, and after a while can’t
be cleaned/lubed into life.

Don’t think I’ve ever snapped a cable. Mind you until this year had never
snapped a hanger...

Now that they are making replaceable hangers the aluminum material is of
the wrong alloy and is very brittle. I don't think that this is to allow
break away in case of a crash or to make people buy more of them but
simply that alloy is just cheaper than hell. It appears to be almost pure aluminum.

These where both OEM parts, ie two separate bikes, one is fairly new, other
is 6 or 7 years old now. In both cases due to COVID19 restrictions I was
riding in well bog.

Ie have no reason to believe was any design fault.


Campy record or Chorus cables are lined with nylon I believe and with
stainless cables. Using these I don't expect any stickiness or grabbling
of any sort. I can't say that I was particularly impressed with Shimano
small parts like their cables and replacement parts. Of course, perhaps
your weather conditions are sufficiently glum that you have to watch out
for that sort of thing.

On the gravel bike the cables seem fairly protected, so generally don’t
have a issue, on the MTB has too much open space so bike shop has hacked
it, ie used a continuous line so there is only where it enters the
derailleur that muck can get in.

On the commute bike which is outside 99.9% of the time water gets in, plus
I have some soggy bits on the commute.

I think I did try some posher cables few years back, but it gummed up as
quickly, sometimes can be cleaned, the MTB and commute bike reach that
point once a year or so, Gravel not so far, it’s 2/3 years old. Though it’s
used in much kinder conditions.

Unlike you hiding far away in a foreign country, Scharf is only a couple of miles away and needs new teeth anyway. Jeff is on his final legs and will very soon be gone and that is where all of his angst comes from. Jay has lost most of his income to those "mostly peaceful demonstrations" and like everyone else with good sense is ready to flee the burning building. You are here for one reason, to feel like you belong somewhere. Well you are welcome to the point you begin your high school crap of ganging up on someone. Then you will discover that your gang rapidly disappears.

Well sure enough the old cable looked fine when I pulled it out no fraying but I put a new cable one. Really a minor price to pay for not worry as much about snapping them on a ride. Actually I am pretty lucky I get 3-4000 miles before they snap or need to be change. No not going to Di2 my 6800 shifts smooth and silent.

I have no understanding of how you can do this. I did break an old steel cable that the Chinese were selling, or rather that a local was stocking and selling out of his garage. But I have never broken a single stainless cable and I have used some pretty cheap ones. I prefer the top end Campy cables and have never even come close to breaking one AFTER it was installed.. As I was recovering my memories and some manual dexterity I did break some cables while installing them. But that was long ago and far away.

Well it is at the end in the shifter so it frays from the anchor point in the cable. Not like the cable just snaps into 2 separate pieces. If fact the cable really does not break it just pulls apart in the shifter and then you have to fish the parts out and make sure leave nothing behind. Shimano on the new stuff now has a part on the shifter to remove at space to get the cable head out. I have heard on earlier stuff sometimes they got stuck in and then you had to replace the shifter. There is even some place they have a way t drill through the shifter to get the cable head to spare the shifter.

But frankly if you want to know the truth on why it happens to me is because of all the power I produce in the hands on the shifter. I mean I can drop some serious power numbers up there when I take the swipe 🤣

Shimano never used this design in which both cables come out under the tape. This is a fairly new design and it is a funny design in which you poke the cable through from one side, remove a compartment cover and push the cable at a 90 degree angle up though a small passageway. I had misgivings about it when I saw it but it appeared to work fine on my 105 stuff on a cyclocross bike. I would have used what I think is called an Archimedes wheel-like mechanism.


The dual internal cable, AFAIK, started with the second generation 10sp (10 years ago) and uses a similar winding mechanism, but the cable now takes a hard turn in the lever, which is not where it breaks -- but those hard turns do put high stresses on the internal guides. The 6700 had a much more straight-forward cable path, and I don't know why they changed that up for the 6800. I think cable failure has been in basically the same place in all the STI shifters -- about a CM from the button head.

You have already told us that you only rarely ride a bicycle anymore
That's mostly correct. What I actually said before you twisted the
meaning is that I am no longer able to properly ride a bicycle. If
you want, I can explain the medical problem that created this
situation. I still have two bicycles, which I occasionally ride short
distances.
so perhaps you might want to explain what you're even doing on this group?
Perhaps? That suggests that I can perhaps choose not to explain. So,
I won't explain because you don't need to know and I don't feel like
justifying my presence.

However, I can offer you a fair trade. I'll answer your question if
you explain why you reply to every single thread, statement, question,
and comment in R.B.T. I believe that I understand the motivations for
your other odd habits, but the need to add your uninformed and
unsubstantiated opinion to every discussion has me mystified. Why?

You probably don't trust me to provide a genuine answer to your
question, so I'll go first if you agree to answer my question in a
similar manner. Deal?
You have also chosen not to explain what in the hell you know about digital engineering, embedded systems and programming so that you could explain what I didn't know. Instead like an English teacher you've chosen to pick my resume apart for its spelling errors and not the thousands of human lives I've saved.

You are the one that decided to insert yourself into this discussion after that moron Frank chose to tell everyone I was lying about hitting a tree branch because he could find street pictures of that area only 5 years old. So don't pretend that you have ever had any effect on the world around you because I've spent my life doing just that whether it was volunteering for the Air Force or being part of the construction of the world's largest time sharing computer of the time. The job I had before the concussion was designing and programming devices for the detection and treatment of Cancer. Did your radios help that? Half of this scientific world has been changed by the things I have done. And I have a right to be proud of that.

Of course we could always go with Jay's idea that if I designed anything of value I would have a patent on it. Elon Musk doesn't have any patents but I should. Charley Button owns no patents of his intercoms and radios but I should. I have never even heard of a development engineer owning a patent but dollars to dimes Jay could find one.

If you want to be a part of a discussion talk about things you know and not for the reason that you want to complain about how badly I treat you after you started it.
An accurate quote would be appreciated. What I said is that IF you had any significant inventions, your name would be in the USPTO as a an inventor if not as a patent assignee/owner. Elon Musk at the USPTO: https://tinyurl.com/ze3jzzcw At least he is mentioned -- and his company owns many patents: https://tinyurl.com/5fjj8kh5

Elon is mentioned in this patent which we should apply to you: 10,963,467 "Determining whether a user in a social network is an authority on a topic." You should go read that. Here is the abstract:

"A method involving obtaining a first plurality of topic groups (TGs), each having a membership of accounts, identifying a first plurality of accounts as authorities for an expertise topic, obtaining a second plurality of TGs with a number of accounts as members, wherein the first plurality of TGs comprises the second plurality of TGs, identifying a first frequent account which is a member in at least one of the second plurality of TGs, adding the first frequent account to the authorities of the expertise topic to obtain a second plurality of accounts as the authorities of the expertise topic, determining a third plurality of TGs in which a second number of accounts from the second plurality of accounts are members, determining that another frequent account is a member in one of the third plurality of TGs, and obtaining a ranking of accounts that are an authority on the expertise topic."

Got it?

By the way, there is nothing about your accomplishments anywhere except in your LinkedIn page. If you invented half of the scientific world, one would expect to see you mentioned somewhere, if not the USPTO. Maybe a professional journal, association news letter, company press release, police blotter -- well, you did make the police blotter.

-- Jay Beattie.
Your world must certainly be small if what I did seems to you to be the half of the scientific world. Tell us, what is it like to live on a small planet? Do they have mostly peaceful protests that burn a town down?


Folks, I think we have to seriously consider the possibility that Tom is
well into dementia. It's sad, and I'm not joking.

In his post about 33 lines above he said "Half of this scientific world
has been changed by the things I have done." But at the end of the
quoted material just above he said "Your world must certainly be small
if what I did seems to you to be the half of the scientific world."

So he can't remember what he very recently said. This example is far
from unique.

I don't know how to deal with someone whose mind is slipping and who
spouts nonsense. I've read that with a family member, one tactic is to
say "Yes, and... " then pivot the conversation to something pleasant and
distracting. Pretend to agree, then deflect. But I can't see that
working here.

Is there a psychologist or therapist in the audience? Again, I'm serious.

Perhaps Tommy has read the same suggestion that you have about pivot
the conversation into something else... he does it all the time.


Unlike you hiding far away in a foreign country, Scharf is only a couple of miles away and needs new teeth anyway. Jeff is on his final legs and will very soon be gone and that is where all of his angst comes from. Jay has lost most of his income to those "mostly peaceful demonstrations" and like everyone else with good sense is ready to flee the burning building. You are here for one reason, to feel like you belong somewhere. Well you are welcome to the point you begin your high school crap of ganging up on someone. Then you will discover that your gang rapidly disappears.


And weird Tommy when accused of changing the subject to deflect the
fact that (once again) he doesn't know that he is talking about (you
won't believe it) changes the subject yet again.

A few miles into my evening ride on my cable-shift Emonda -- with my
wife pushing me on her ebike, I shifted to go up the next hill and
snap -- immediate downshift into 34/11. Great. In the middle of a
9% grade, that turned at the top to another climb, but a short one.
I tacked a bit, got home and then jumped on the Di2 disc Synapse and
started over. Heavier with fenders, etc., but still a nice bike.
The discs, BTW, don't drag at all. Thank Buddha for that reliable
Di2.

The good thing about the latest Ultegra levers is that there is a
trap door under the lever body, and you can remove one screw, take
out the door and grab the broken cable and end. No more fishing it
out of the lever. This is the second time in 20 years on STI that
I've broken a cable. Before that I broke a friction bar-end cable in
the middle of a tour. I had a spare.


I guess when you've been riding the Di2 setup for the same time &
distance you'll be able to make a more reasonable comparison.

I'm still waiting to break a cable after more than 30 years of using
cable actuated gears and brakes.

I tend to have to replace as the cable gets sticky, and after a while can’t
be cleaned/lubed into life.

Don’t think I’ve ever snapped a cable. Mind you until this year had never
snapped a hanger...

Now that they are making replaceable hangers the aluminum material is of
the wrong alloy and is very brittle. I don't think that this is to allow
break away in case of a crash or to make people buy more of them but
simply that alloy is just cheaper than hell. It appears to be almost pure aluminum.

These where both OEM parts, ie two separate bikes, one is fairly new, other
is 6 or 7 years old now. In both cases due to COVID19 restrictions I was
riding in well bog.

Ie have no reason to believe was any design fault.

Campy record or Chorus cables are lined with nylon I believe and with
stainless cables. Using these I don't expect any stickiness or grabbling
of any sort. I can't say that I was particularly impressed with Shimano
small parts like their cables and replacement parts. Of course, perhaps
your weather conditions are sufficiently glum that you have to watch out
for that sort of thing.

On the gravel bike the cables seem fairly protected, so generally don’t
have a issue, on the MTB has too much open space so bike shop has hacked
it, ie used a continuous line so there is only where it enters the
derailleur that muck can get in.

On the commute bike which is outside 99.9% of the time water gets in, plus
I have some soggy bits on the commute.

I think I did try some posher cables few years back, but it gummed up as
quickly, sometimes can be cleaned, the MTB and commute bike reach that
point once a year or so, Gravel not so far, it’s 2/3 years old.. Though it’s
used in much kinder conditions.


I keep a touring bike out back in case something happens to my bike of I
have one of those occurrences of my eyes pointing in difference
directions and I get in a wreck and lose my license. It has never
occurred when I'm driving and I would instantly pull over if it did, but I am prepared.

Whoosh!

Are you talking about a seizure?


No, it is an occasional reaction to the medication. It only lasts a minute of so and it is usually when I am sitting down in my house. It has never happened on the bike except one time an I simply closed one eye so I could safely pull to the side and wait for it to pass. It has never happened while I was driving but then I don't drive close to when I take the medication. After 20 minutes after I take the medication it can happen. I suspect it is a rapid absorption and had started eating before taking the medication. In two weeks I see my Neurologist again and we can discuss what happened last night. I had an episode in the middle of the night that felt like what he thought was a miniseizure. When I got up this morning I realized that I had taken my evening medication twice. Since it screws up your short term memory I put the pills in a plastic container market with morning and evening and day of the week. I was busy when the alarm went off so I delayed taking the medication. Then I must have forgotten that I had taken the medication and did it again despite the fact that it was marked. So these problem may all be attributable with an overdose rather than an underdose.
