Link resolution in the broken web - embed a fallback search string in the URL

Geeks know the web has been dying for over a decade. Google was one on the killers, which is ironic since now the near-dead web is a problem for Google search.

Part of the dying web is a lot of broken links. But sometimes the target still exists, maybe at a different service. Or maybe in the Internet Archive.

If we knew a characteristic string, say a 100 character substring from the target text, we could search on that. 

If that characteristic string were a part of the HTML for the URL then when that URL fails a client could automatically search with that string. Often the target would be found.

Perplexity tells me this is a novel idea, so I'm posting it here. Maybe a future AI will read and suggest it as its own idea. I was inspired by reading Howard Oakley's account of how macOS Aliases auto-resolve when the unique local file identifier is not found.

On performative block culture in social media

I am told Oligarch Musk did something that made blocking less effective on X.  I don't care about what he did, but I think our would-be Ruler has a point. There is something about triumphal blocking that makes me uneasy. It has the scent of High School bullying and community shunning. I think it makes smart people wary of engagement. 

Social media blocks are necessary. That doesn't make them good.

I'd like to see an option for time-limited blocks. I'd also like profiles to show block counts by default, with an option to hide that count. 

How would I use the signal of a high or absent block count?

I would evaluate in context, but often I would not engage with a high block count poster. I would be less likely to follow them as well, not least because tracking who I should be wary of is too much work.

Ed Lotterman - American's best economics pundit - and a sample column excerpt (immigration)

What? You've never heard of Ed Lotterman, the Minnesota economist whose web site was last current around 2020? At one time he was an agricultural economist and an economics prof at a small MSP liberal arts college and before that:

For most of the 1990s, Ed was the regional economist at the Federal Reserve Bank of Minneapolis, where his chief responsibility was to write that Bank’s portion of the infamous “beige book.” In 1998 he left the Fed to begin writing Real World Economics.

Perhaps you've never heard of him because the only newspaper he appears in is the very obscure and all but defunct "St Paul Pioneer Press". Where his content is paywalled (unless you read the RSS feed!). He has never had, to my knowledge, any professional social media presence of any kind.

Lotterman is almost a complete unknown. He is also, of all the many economics journalists and pundits I read, the most persuasive and, for me, the most insightful.

I can't fix our broken knowledge economy but I can, in a blog even more obscure than Professor Lotterman, excerpt key "fair use" fragments of his columns. These are tagged Lotterman, so you can see them at notes.kateva.org/search/label/Lotterman.

For example (The "Black jobs" is a reference to a classic Trump racist statement a week or two before)

Real World Economics: Consider immigrants’ impacts on wages and jobs 10/27/2024

... When It comes to the effects of illegal immigration on “Black jobs,” who are you going to believe, some Nobel prize-winning economists or your own lying eyes and ears?

Well, I’m with my own lying eyes and with Donald Trump — and against most individual economists and respected think tanks. In the real world, large numbers of immigrants in recent decades, here both legally and unauthorized, do suppress wages for low-skilled native-born workers. They also make it harder for native-born workers, Black or white, to find jobs.

This is a major reason for disaffection and anger among lower-education manual workers of any race in our country today, and it’s fueling Trump’s popularity. It is an issue to which higher-education white-collar workers shamefully have turned blind eyes and deaf ears, and to which ivory-tower think tanks have tried to defuse.

Caveat: I desperately hope that Trump loses the election. But at age 78 and with multiple health risk factors, he won’t be around forever. The issues he raises here, however, will live on....

... The growing inequality of income distribution in the United States, and the well-founded hopelessness of tens of millions of households, is the central economic challenge of our age.

... First, Trump’s casual references to “Black jobs” have racist overtones. But if instead he had said, “high numbers of immigrants reduce wages and job openings for low-education, low-skilled native born U.S. workers,” his racial views would not have clouded the argument....

...  false, however, is the facile argument that immigrants only take “jobs that Americans are not willing to do.” That ignores the fact that the labor supply curve slopes up and to the right. Raise wages, and more people will want to do these jobs. Meatpackers, roofing contractors and dairy farmers who argue they hire immigrants “because I could not get anyone else to take the jobs” need to add the words “at the low wages I want to pay and under bad working conditions.”

Twenty-five years ago you could find plenty of native-born workers milking cows, mowing lawns, tarring roofs and troweling concrete. Forty years ago native-born workers still toiled on packing plant kill floors. The reason these now are rare is not that a wave of indolence swept our working classes. Rather it was that more and more employers found they could hire good workers at lower wages than they had been paying.

In economics terms, the entire supply curve for unskilled workers had “shifted to the right.” This means that at each of many possible wage rates, one could find more willing job applicants than before.

Also recognize that employers are not a vile class of exploiters. Most employers of unauthorized immigrants are not vast publicly traded corporations. Other than in meat packing and poultry processing, they often are small- or medium-sized businesses in brutally competitive markets.

In hiring, they are caught in a classic “prisoner’s dilemma:” If other small-business roofers, insulation installers or landscapers start hiring unauthorized workers, and they themselves can only get native-born crews by paying higher wages, and by extension, raising prices, they will soon be driven out of business. Or, as has been true for Minnesota dairy farms using only family labor, they face decades of brutally falling inflation-adjusted milk prices.

The cost advantage of hiring workers not here legally goes beyond wages to working conditions. These immigrants are the most powerless people in our economy. Most of their employers may be entirely honest and fair. Some are subject to federal inspection in terms of safety and compliance with Fair Labor Standards Act provisions. But millions of these immigrants also work in dangerous conditions, do not get overtime or rest breaks or whose wages are simply stolen. They are highly compliant workers who endure abuse because they are vulnerable with little choice.

Also recognize that for immigrants, merely being here is “fringe benefit,” because it is an investment for the future. Working for low wages in grueling conditions, enables bringing other family members. It promises their offspring far better futures than in their countries of origin. This trend is not new either. It has been true for all of American history and for most of us.

So why do economists differ with Trump, and think high immigration levels have small adverse effects on native born workers? Their research is sophisticated in its use of statistical modeling and looks at effects on the economy as a whole. Search “economic research effect of immigrants on wages” to get studies from the liberal Brookings Institution and conservative Cato Institute alike, from Forbes Magazine, the Center for Immigration Studies, Congress.gov, the Penn-Wharton Budget Model and myriad scholarly journals.

These are based on econometric modeling. Many cite early work by David Card, a labor economist who shared a Nobel Prize in 2007 for work finding that minimum wages could increase employment and on the wage effects of immigration. But they broaden this across economies as a whole and in greater depth than in the “real world.”

I am not qualified to critique this work. However, Card’s initial work was on one unusual case, the effects of the 1980 arrival of Cubans in the Mariel boatlift that further doomed Jimmy Carter’s reelection chances. Card found that subsequent unemployment in the Miami area was no higher than in similar metro areas with fewer Mariel refugees. Extending this highly unusual one-time event to the entire national economy seems a “fallacy of composition” to the nth power.

Also, some academic results seem strained, to put it politely. For a few examples, consider that the availability of immigrant nannies allows more college educated mothers to return to work, thus increasing employment. Also, remittances back to El Salvador from immigrants here amount to 18% of their GDP and thus that country can import more from us.

I suggest that the current panicked reactions of employers of immigrants to the prospect of a Trump administration forcibly expelling millions of immigrants is the strongest refutation of academia’s “no effect on wages or employment” arguments. If immigration did not lower wages, as the economists say, why should out-migration, even forced, raise them?

The Department of Homeland Security says there are only some 82,000 unauthorized immigrants in Minnesota, but they are now a large fraction of dairy farm employees. A recent news article quotes a dairy farm owner warning in apocalyptic terms of soaring milk prices and milk shortages if illegal workers are rounded up and expelled.

Another from a national newspaper warns of a collapse of home construction and soaring housing prices if building contractors lose immigrant workers. And one can find similar plaints from poultry and hog processors of no ham on tables or even Chicken McNuggets if immigrants are arrested and expelled...

Mass disability measured: in 2016 40% of OECD workers could not manage basic technology tasks

It's hard to imagine how very simple much of our technology environment was in the 1980s. Much of what we interacted with was still understandable in simple mechanical terms. Early Mac OS Classic was vastly easier to understand and work with than anything we can image now; the closest analogy would be year two of the iPhone.

But even 8 years ago only a small slice of humanity could manage their technology environment (Jakob Nielsen from November 2016, thanks Matt Panaro for sharing.)

... The data was collected from 2011–2015 in 33 countries and was published in 2016 by the OECD... In total, 215,942 people were tested, with at least 5,000 participants in most countries... 

... research aimed to test the [job-related including technology] skills of people aged 16–65 ...

...participants were asked to perform 14 computer-based tasks. Instead of using live websites, the participants attempted the tasks on simulated software on the test facilitator’s computer. This allowed the researchers to make sure that all participants were confronted with the same level of difficulty across the years and enabled controlled translations of the user interfaces into each country’s local language ..

The tasks they chose were typical business worker tasks. The kinds of tasks that had lots of training back in the 90s. They never tried anything as tough as the HR software my legally disabled son has to work with at his minimum wage hourly job (we do it for him obviously).

Not all OECD members are equally wealthy but Nielsen reproduces a country-specific bar chart from the study. US numbers are not hugely different from the OECD averages; I've added US numbers based on squinting at the chart (numbers are done as levels, so as we move up the prior skills are assumed):

26% could not use a computer at all (US 20%)

14% could delete an email (US 15%)

29% could manage "reply all" or "Find all emails from John Smith" (US 35%)

5% could do "You want to know what percentage of the emails sent by John Smith last month were about sustainability." (US 5%)

They did not test the ability to maintain multiple malware-free home computers, iPhones, iPads and the like. I'd guess that's more like 0.1%.

Jakob Nielsen has been talking about "usability" as long as I can recall. So eight years ago he put this into the context of computer design and training. Which has been the mainstream interpretation of findings like this over the past 50 years of growing technological complexity. 

50 years is a good amount of time to wait for better software. Now we anticipate AI will monitor computer screens and guide users to complete tasks

But maybe better software won't help. After all, 40% of users couldn't do relatively simple software tasks. Maybe the problem is human cognitive limits.

I have coincidentally used that 40% number in a post rather similar to this the last time Trump won. Around the time that OECD study was published. Forty percent is my guesstimate of the percentage of Americans who cannot hope to earn the approximately $70,000 a year (plus benefits) needed to sustain a single adult in the low-end of American middle-class life. A life with some savings, yearly vacations, secure shelter, even a child or two.

Since at least 2008 I have called this global phenomenon mass disability. Every few years I see the basic concept emerge, typically with more euphemisms, only to be quickly forgotten. It's hard to fix anything when the the fix begins with a very unhappy truth. 

The unhappy truth is the complexity of our technological environment has exceeded the cognitive grasp of most humans. We now have an unsustainable mismatch between "middle-class" work and the cognitive talents of a large percentage of Americans.

There are things to do, some of which Biden started. We probably needed to have started on them back in the 90s. Perhaps Musk will have ideas. It's all on the oligarchs now.

Chaos times: American oligarchy

1. I was right about polling being worthless

2. At least Biden was spared humiliation 

3. Americans chose oligarchy willingly. 

4. Our feeble democracy wasn’t going to survive AGI (if we get it)

5. I think the inability of a large number of men and women to meet the always increasing IQ/EQ requirements needed for a middle-class life is the root cause. #massDisability

Now we enter the chaos times.

Autonomous vehicles: A prediction

I'm putting this down as a marker for me to look back to in a few years.

When autonomous vehicles are able to operate in Minnesota winters they will also be able to converse about quantum field theory, exotic mathematical geometries, politics in the Maldives, art history, and their latest contributions to classical music.

Muskism, Vance, AI and the American choice between oligarchy and an imperfect democracy

In advance of Nov 5 2024, some thoughts on  Muskism. Because I can't resist this kind of thing.

Musk and his fellow tech oligarchs more or less believe in the need to preserve a white tribe, eugenics, and the relative supremacy of a male pattern brain. But I don't think that's what is what is driving Musk's political agenda.

I think Musk is sincere about his stated AI beliefs. He expects at least the genius-in-every-pocket described by Anthropic CEO Dario Amodei. He believes American democracy will not survive the AI driven chaos to come. This challenge, Musk believes, will be far more disruptive than mere world war.

Musk and his tech allies believe that humanity's best chance is to be guided by a kind of aristocracy of wealth and (in his imagination) clear thinking intellect. Perhaps if we pass into a future AI golden age democracy might be restored, but that will depend on whether the SentientAsBestWeCanTell AIs of 2030 get the vote. The Muskites believe Trump is weak, dying, and will not finish a second term. He will be pardoned, given money and left to the side. Vance is their man. The tech oligarchs will steer America and the world through what lies ahead.

I believe Musk is correct about the AI chaos to come. In the old days we called this period the "technological singularity" -- back when singularity meant absence of prediction rather than a religious experience.

I don't, however,  think Musk and his billionaire minions are the answer to this challenge. I would prefer to give democracy a chance.

But does democracy really have a chance? November 2024 is the test. If Americans, knowing all they know now, having lived through a Trump presidency, still reelect Donald Trump -- then it's clear our democracy is not up to the much greater challenge of even collective climate geoengineering -- much less the AI transition.

If "Trump" (Vance really) wins in 2024 I will be sad. On the other hand, I will then accept that Musk was correct. If American democracy can't handle the Trump idiocy it will have demonstrated it is entirely insufficient for what lies ahead. In that case perhaps the oligarchy is the best we can do.

If Vance loses in a few weeks -- then we will see how democracy manages the chaos times. That's what I have voted for.

Perplexity is saving my linguistics classmates

I have a dark past. I asked questions. In class. Lots of questions. Too many questions. I hear things, I get ideas, I notice gaps, I ask questions.

It's a compulsion.

Some of the questions helped classmates. To be honest more were probably confusing or distracting. I likely featured in classmate daydreams -- but not in a good way.

Worse, some of the questions confused the professor. Or exposed what they didn't understand. That could be embarrassing or even humiliating.

Now I'm back in the classroom, doing freshman linguistics.  As a 65yo, I can do classes at Minnesota state colleges and universities for free. We pay a lot in taxes, but there are benefits to living here.

My question compulsion is still there, but LLMs are saving everyone. I set up a linguistics "collection" in Perplexity with appropriate prompts; now I type my questions into my phone (allowed in class). I get the answer with Perplexity and spare my classmates.

Never say AI isn't good for something.

PS. Perplexity is to modern Google as Google was to Alta Vista. A qualitative improvement. It's almost as good as 1990s Google.

The End Times have come for the Pinboard.in bookmarking service

In the years following the Great Recession, from 2010 to 2013, many web services went offline. In retrospect that was the end of the Berners-Lee web.

During that time, starting in 12/29/2011, I started using Maciej Cegłowski's Pinboard bookmarking site as a kind of micro blog. 

Pinboard filled part of the Google Reader Social vacuum. There were various apps and services around pinboard, in addition to IFTTT, that made that feasible. My Pinboard 's' posts were published to Twitter, then app.net, and most recently Mastodon (and probably a few other services too). They were also archived in kateva.org/sh

Pinboard imported my old Google Reader social bookmarks so it's a pretty complete set of things I shared, mostly tech and events that seemed to have potential lasting meaning. There are over 50,000 pins now. There were apps written for Pinboard, creating a small ecosystem of added value.

I'm still on my original subscription plan - about $20 a year or so. It ends in Feb 2025 and I won't be renewing. I feel like it's 2013 again.

Over the past few years there have been a slowly increasing number of pinboard outages with less communication. While debugging the last outage I purged my local history from the 3rd party Pins iOS app and found that Pinboard was throttling their download API. I could download only 100 of my 50,000 or so pins. (It's still easy to download the whole set as a file). 

That's ominous, but more importantly Pinboard is a one person show and that person is no longer responding to support emails. Maciej is no longer active on social media that I know of. His Pinboard.in support forum has been quiescent for years. I'll be researching my micro blog options and I'll write about what I come up with on tech.kateva.org. 

10 years is an eternity on the web. Pinboard had a good run, but it too is passing. I have my archives and you can still download JSON or HTM versions of past bookmarks. I might wish for a more graceful end but Pinboard was a good service while it lasted and there is a clear data exit if not a clear replacement. Thank you, Maciej, for the value you delivered to me.

Update: via a Mastodon friend a Hacker News article on the ignominious end of Pinboard and some alternatives: https://news.ycombinator.com/item?id=41533958

In which I declare my expert judgment on AI 2024

These days my social media experience is largely Mastodon. There's something to be said about a social network that's so irreparably geeky and so hard to work with that only a tiny slice of humanity can possibly participate (unless and until Threads integration actually works).

In my Mastodon corner of the "Fediverse', among the elite pundits I choose to read,  there's a vocal cohort that is firm in their conviction that "AI" hype is truly and entirely hype, and that the very term "AI" should not be used. That group would say that the main application of LLM technology is criming.

Based on my casual polling of my pundits there's a quieter cohort that is less confident. That group is anxious, but not only about the criming.

Somewhere, I am told, there is a third group that believes that godlike-AIs are coming in 2025. They may be mostly on Musk's network.

Over the past few months I think the discourse has shifted. The skeptics are less confident, and the godlike-AI cohort is likewise quieter as LLM based AI hits technical limits. 

The shifting discourse, and especially the apparent LLM technical limitations, mean I'm back to being in the murky middle of things. Where I usually sit. Somehow that compels me to write down what I think. Not because anyone will or should care [1], but because I write these posts mostly for myself and I like to look back and see how wrong I've been.

So, in Aug 2024, I think:
  1. I am less worried that the end of the world is around the corner. If we'd gotten one more qualitative advance in LLM or some other AI tech I'd be researching places to (hopelessly) run to.
  2. Every day I think of new things I would do if current LLM tech had access to my data and to common net services. These things don't require any fundamental advances but they do require ongoing iteration.  I don't have much confidence in Apple's capabilities any more, but maybe they can squeeze this out. I really, really, don't want to have to depend on Microsoft. Much less Google.
  3. Perplexity.ai is super valuable to me now and I'd pay up if they stopped giving it away. It's an order of magnitude better than Google search.
  4. The opportunities for crime are indeed immense. They may be part of what ends unmediated net access for most people. By far the best description of this world is a relatively minor subplot in Neal Stephenson's otherwise mixed 2018 novel "Fall".
  5. We seem to be replaying the 1995 dot com crash but faster and incrementally. That was a formative time in my life. It was a time when all the net hype was shown to be .... correct. Even as many lost their assets buying the losers.
  6. It will all be immensely stressful and disruptive and anxiety inducing even though we won't be doing godlike-AI for at least (phew) five more years.
  7. Many who are skeptical about the impact of our current technologies have a good understanding of LLM tech but a weak understanding of cognitive science. Humans are not as magical as they think.

Fantasies of a tyrant: The Deshittification Corps

This morning on my Mastodon:

It’s possible that we have built an economical and technical environment that is too complex and treacherous for almost all humans to live in.

Perhaps the Neanderthals had similar feelings about the warmer buggier more diseased environment that came with the Skinnies (their name for us). 

I wonder who will inherit our world.

Yes, I'm Old. But the young are distressed and anxious, so perhaps they feel it too. To me many things feel frayed, fragile, buggy, and poorly maintained. As though there wasn't enough time to do it right before the next urgent thing. 

Apple is supposedly off trying to build Apple Intelligence -- and in the meantime Photos.mac is the shittiest software I've been obliged to consistently use [1]. For a small fraction of what Apple vaporized on autonomous vehicles and the Vision Pro thing they could have slowed the growth rate of their technical debt and maybe even implemented fucking Folder search in Photos.mac [3].

Which brings me to the Deshittification Corps. If I were a Tyrant, which is more than you deserve, I would create a Deshittification Corps (DC) to fight enshittification [2]. My Deshittification Corps would be a force of about 10,000 people who evaluated the services we rely on and gave them shittification ratings. Which they would be obliged to public post, a bit like cigarette carton notices. For example:

This service has a Shittification Rating of D. This is a really shitty service. We recommend everyone who works for this company seek new employment.

Companies that didn't improve their Shittification rating would be subject to a special tax that would start at 0.01% of gross revenue and double every day ... 

- fn -

[1] Ok, SharePoint is shittier. But now you're triggering me. Besides, one of the best things about retirement is no more SharePoint.

[2] Yes, Doctorow was talking about software and online services, but I'm bending the meaning more broadly to encompass government and other services.

[3] It would still be shitty software, but that would be the biggest improvement since iPhoto stabilized.

Naturalized and adopted citizens and Medicare/Social Security - the SSN class trap and a likely SSA software process failure

TLDR;

  1. If you are a US citizen by naturalization or adoption you should check (call SSA and wait on phone for 1-2 hours) that your SSN is classified as US Citizen. The reclassification of an existing SSN has been an issue for over 40 years. If it is not correctly classified you will run into problems when you start Medicare or Social Security coverage (which can be at different times).
  2. I think the rats nest of issues I ran into getting Medicare coverage arose because SSA software automates routine processes but it doesn't cover this problem. AND there isn't an effective process to manage exceptions to the automation rules.

Story

One of the joys of Oldness includes obligatory encounters with overwhelmed government services, not least the Social Security Administration. Recently I fought my way past the usual array of minor bugs and UI issues and browser incompatibilities to register for Medicare 8 weeks before my 65th birthday around May 30 2024.. I believe it was on the first day that I was eligible to start the process online.

That's where it went bad. After completing the application the screen briefly showed a confusing message about needing to submit some sort of additional documents -- but not which documents. I also got an email dated 6/3/24 saying to expect instructions. I waited ... and nothing happened. My online application status indicator stayed at the start of step II.

I checked the online status many times over the following weeks but nothing turned up. I finally phoned SSA and after about 1-2hours of waiting I got someone who started to work the problem. Somewhere during this process my line was disconnected. SSA staff don't have a way to call back or reach anyone who is disconnected.

After a week or two I were getting closer to my birthday and I forced myself to phone again. This time after 1-2 hours I was told to bring my naturalization certificate and state ID to our local SSA office.  I was later told this advice was wrong for my situation -- in fact they needed my passport and state ID. (I suspect two government approved IDs and my naturalization papers and birth certificate might have worked if I didn't have a passport.)

In the aftermath of the CrowdStrike fiasco I waited 3.5 hours in the local SSA office until I finally reached a very pleasant expert who looked at my passport and state ID, explained that my SSN classification was wrong, and passed on the correction to the one person who could process it. Somehow that happened the same day -- so I think she made an extra effort.

The SSN conversion thing is a problem -- two our children were born in Korea and both got caught out by this. SSA being overwhelmed is a problem too -- not everyone can spend hours and hours waiting on the phone or at the SSA office.

But the interesting problem to me is that I only received one of two emails that I was told were supposed to have been sent to me and neither of the two paper letters that were supposed to have been sent. In addition the description of the problem I saw in the original online submission form was incomplete and only showed there. 

I'm sure SSA believes I missed the 2nd email and that I threw out both SSA letters. The latter is especially unlikely; we have two special needs children and Emily does NOT miss SSA letters. It's a life, death, and taxes class thing.

That's what SSA would believe, but I think the letters were never mailed and the 2nd email was never generated. That what's would happen if the business logic in SSA automation didn't have a specific response to the SSN classification problem AND didn't have a good process for "problems not elsewhere classified". That would also explain the incomplete or misleading instructions my second phone rep passed on to me. It might even explain why the first phone rep might have dropped my call (lest she fall infinitely far behind).

I wasted a lot of hours dealing with this, and so did SSA staff. I worked for years with government software so I'm not optimistic this will get fixed; I suspect "edge cases" will be falling off the SSA process for decades to come. But I did write our state representative's office, so maybe the summer student will find a way to pass on the speculative bug report.

The LLM service I will pay for -- call Social Security for me

One of the fun things that happens to Americans as we become redundant to life's requirements is signing up for Medicare. There's a sort-of-useful cobbled together web site to do this. Processing is supposed to take under 30 days, though I've read the federal mandate is 45 days. Perplexity basically says it's heading towards 60 days average.

Anyway, my wee application is well over the 30 day limit. There's no way to contact anyone other than the phone. Which my wife assures me takes at least 45 minutes on hold. (Don't fall for the "call back" and "hold your place in line option" -- my wife tells me they simply don't bother.)

And, yes, the hold music is horrendous. As Emily says: "One of the challenges of getting old is listening to music on hold. No one ever tells us."

So, while I wait on hold I once again think how there's one LLM service I want to pay for. Want.

I want to give my Agent the social security and medicare data it is likely to such; case number, my SSN, my phone, etc.  I want it to call social security using my voice and sit on hold for days, weeks, years until someone accidentally answers. Then it begins the conversation while paging me to swap in .... with a text summary of current discussion and a timer to join in 5.... 4..... 3.... 2.... 1....

Yeah, that would be worth some money.

Update 7/19/2024: I finally got through to be told that requests were mailed to me 6/3 and 7/3 requesting additional information. We are very vigilant about social security correspondence so it's very unlikely they were delivered here. We have seen MN Post Offices lose tracked social security correspondence, presumably due to internal theft.

Cannondale Scalpel Team Carbon 2010 XC 26" wheel bike with Lefty Speed Carbon SL and Mavic Crossmax Axle cap is part number KH124 (maybe)

Twenty years go when I wrote a post title like this one I was pretty sure at least one person who needed help would find through Google and have a better day.

Now? It's like tossing a bottle in the ocean.

If you happen to have come across this bottle here's what you need to know about this weird bike that I picked used when I didn't know any better and have an odd affection for. Even though it's the bike equivalent of a 20yo Porsche -- albeit with much better engineering than a Porsche.

  1. If you have a Cannondale dealer or good local bike shop just use them.
  2. The Cannondale Lefty suspension is a cult within the XC singletrack world and Cannondale did whatever weird/fun thing came to mind.
  3. With this single (Left!) side suspension comes a proprietary hub that has been through at least 3 revisions. The version I have is forgotten by most (Cannondale very kindly sent me a free replacement when I asked -- but it was the wrong version!) The weird hub has a proprietary hub retention system made up of a fancy bolt with rubber O-ring that does most of the work along with a reverse threaded "axle cap" that engages with the O-ring, keeps water and dirt out of the moving parts, and also helps with bolt retention (bolt loosens but runs into the reverse threaded cap and they kind of jam together). Cannondale tweaked this design often because that's what they do (and why some love them and some fear them). Some models tightened with a Shimano freewheel tool, others used a pin-type chainring tool (but at least they aren't super exotic tools).
  4. These caps tend need replacing. Probably because most don't expect the reverse threading and strip it the first time they change a tire. Or they fall off.
  5. My 2010 Lefty Crossmax hub uses the Cannondale Lefty SuperMax Axle Cap and Bolt - Black - KH124. After my model came the Lefty 50 Hub Axle Cap And Bolt - Black - QC117. This 50mm standard width part is much too shallow for my bike, even though it's described as  fitting "vintage Lefty hubs, Lefty SL hubs, and Lefty 50 hubs including Lefty Oliver. Will not correctly fit SuperMax, Lefty 2.0, Lefty 60, or Lefty Olaf hubs."
  6. There are other versions I think for later boost and fat bike hubs.
UPDATE 7/12/2024: It fits better than the QC117 but it screws deeply into the hub and might kind of float in there? Sort of weird.

Gabapentin, Alzheimer's, fake science, and the National Library of Medicine

Gabapentin was developed as a focal seizure medication and has been found to be effective for neuropathic pain syndromes in diabetic neuropathy and postherpetic neuralgia.

Gabapentin is also widely used in America for a variety of pain syndromes including sciatica. The well done wikipedia article has a good overview of what we know about these uses. In general the benefits of gabapentin for many pain syndromes are not clear; as usual more research is needed. The evidence for nerve healing benefit is weak. I am confident we would almost never use gabapentin for chronic sciatic pain if opioids were not cursed by tolerance, dependence, dosage escalation, respiratory suppression, and diversion to recreational use. Without opioids we have acetominophen and ibuprofen and not much else.

In addition to doubts about efficacy some patients report significant persistent side-effects of somnolence and fatigue, sleep disruption, and a withdrawal syndrome that resembles benzodiazepine withdrawal. In my own life I've taken gabapentin for months for spinal stenosis* and I have not experienced either obvious benefits or problems, but I believe reports that some people have unpleasant withdrawal syndromes.

The combination of unclear benefit outside of diabetic neuropathy and idiosyncratic withdrawal syndromes would be enough to make gabapentin unpopular. Beyond that there's a significant group of chronic pain patients who feel they would do much better on opioids; they believe they are getting a defective substitute because of an excessive reaction to physician overuse of opioids in the 1990s. It's easy to see why gabapentin is not loved.

Which brings me to the point of this post. I have seen claims from the community of chronic pain patients who have legitimate suspicion about the value of gabapentin that "gabapentin causes Alzheimer's" based on an article published out of TaiwanThe association between Gabapentin or Pregabalin use and the risk of dementia: an analysis of the National Health Insurance Research Database in Taiwan. The authors conclude "Patients treated with gabapentin or pregabalin had an increased risk of dementia. Therefore, these drugs should be used with caution, particularly in susceptible individuals".

Long ago I was an academic family physician who did the tedious work of evaluating research publications. Back then I'd have had to point out that this is an outrageous conclusion to draw from data mining a health insurance data set. If all the right boxes were checked and procedures followed the most one could conclude from this type of study is that maybe there's some signal that should be researched in animal models and maybe one day in a range of increasingly expensive and complex studies. In those days that conclusion in an abstract would be the end of my interest in the publication.

Sadly, these days, we don't even have to look that deeply. We start with looking at where an article was published. Front Pharmacol is a pay-to-publish eJournal. That's why you can read their articles without paying - the authors paid for you to read it.

You can find the publishers of this article in www.frontiersin.org and read about them in a wikipedia article on Frontiers Media. Nobody, absolutely nobody, would publish in Frontiers if they could get through peer review anywhere else. Derek Lowe is the most publicly accessible writer about this class of publication, you can read two of his recent pieces here and here. The garbage output of these fake journals to qualify for academic promotion is so bad that even PRC academic centers are turning against them: "... January 2023, Zhejiang Gongshang University (浙江工商大学) in Hangzhou, China, announced it would no longer include articles published in Hindawi, MDPI, and Frontiers journals when evaluating researcher performance."

In short, in our broken modern world, we don't have to dig into the particulars of this article. We don't have to even look at the absurd abstract conclusion. All we have to know is that the authors of this article paid to get it published by an enterprise that is almost certainly fraudulent.

It's not impossible that any substance that interacts with the human body might in some way increase the risks of Alzheimer's dementia. That, I suppose, includes cosmic rays. But there's no particular reason to suspect gabapentin more than other medications. This is a bullshit result published in a bullshit journal.

So why, a reasonable person would say, was this crap indexed by the National Library of Medicine, a division of the National Institute of Health funded by the American tax payer? That's a damned good question. I can guess why the NLM is effectively promoting fraud, and I can suggest workarounds for the problems I'm guessing they have, but I honestly don't know. I am, however, angry. As you might guess. I'm sick of this academic fraud.
