It’s annoying but a proper HR strap fixes all the issues associated with wrist based optical readers.

mtanski · 3 months ago

I know all of the wrist watches experience this issue, but this was extreme like drop from 145->80 for like 60+ min then rapidly shopt back up. Not like a small couple min blip.

This was a near the top end model at the time, and after complaining Garmin support owned up that this was a firmware bug impact all sensors of that generation and it would take 2+ months to fix (took like 5).

But they did send me a HRM for free and I've been using that. So I am grateful that and using it since. But for short rides (like 90 min or less) I don't always remember to think to bring the HRM.

Prior to that I had two lower end Garmin watches, and despite having theoretically lower end HR sensors they did not experience such bugs or drop outs (an unexpected blip every once in a while).

But I think the main point still stands, their software/firmware/UX has not moved in relation with the hardware. Next time I'm in the market I will be consider all the options. Feels like Coros and others have come a long way.

Prob the biggest thing keeping me in their ecosystem is multi sport (variations of bike riding types -- I do all), hiking, strength training, erg, winter sports. But even there the list of strength exercises has not been updated in like a decade.

The hardware side is routinely impressive. The software and business sides leave a lot to be desired.

mtanski · 3 months ago

Cane to say the same.

I have a Garmin "smart" watch (with every app notification etc disabled) and I love the fact that I can do almost two weeks of exercises (ride, walk, gym) without needing to charge it. The bike computers are also solid. But sadly the UX of the software on these leaves a bunch to be desired, and I've been bitten by many software and firmware bugs in the last years... Including months for which HRM would randomly and persistently drop it's value from say whatever the real value (say 145 for argument sake) to 80.

Where is mass market carbon fiber? Expensive carbon fiber parts aren't interesting.

It's not even that expensive if you consider that it's maybe 5k extra now that even a basic car can cost $40000

mtanski · a year ago

Pre tariffs you could get a whole Carbon bike frame from CN (including stem, handlebar, fork) for $500.

And while I'll give that there was variety between vendors, some of them were doing sophisticated layups with multiple grades of wave that withstood a torture tests far beyond the ANSI bike tests.

In fact you could argue they were overbuilt compared to Western brands (at a cost of 100 - 150g) since they didn't want to deal with warranty claims.

Truly amazing, cheap, good quality mass market carbon products.

mtanski commented on Benchmarking Intel, AMD and Graviton Using Erasure Coding Workloads blog.min.io/erasure-codin... · Posted by u/edogrider

Interesting to see Intel still being rather competitive here. My biases had me going in thinking AMD would walk away with the win.

The conclusion:

"Analysis and Conclusion

With this test we were looking to confirm that Erasure Coding on commodity hardware can be every bit as fast as dedicated hardware - without the cost or lock-in. We are happy to confirm that even running at top-of-class NIC speeds we will only use a minor fraction of CPU resources for erasure coding on all of the most popular platforms.

This means that the CPU can spend its resources on handling IO and other parts of the requests, and we can reasonably expect that any handling of external stream processors would take at least an equivalent amount of resources.

We are happy to see that Intel improved throughput on their latest platform. We look forward to testing the most recent AMD platform, and we expect its AVX512 and GFNI support to provide a further performance boost. Even if Graviton 3 turned out to be a bit behind, we don’t realistically see it becoming a significant bottleneck. For more detailed information about installing, running, and using MinIO in any environment, please refer to our documentation.

My knowledge here is rather dated, and I'm unfamiliar with the minio code base... But ~ a decade ago Intel invested a fair amount of effort into optimizing the oss Erasure Coding libraries for Intel CPUs.

Back then CPUs had less cores, RS coding was relatively more expensive and certainly CPU bound on then new NVMe flash devices

It's possible, even likely this is the result of that

"If Texas voters will finally vote in someone who is more like Ann Richards than Greg Abbott, I will believe the mindset is changing."

I think the problem with this is that it rests on a fundamental assumption that someone's primary motivation for voting Republican is bigotry. Polls by the Pew Foundation do not bear this out. Non-college educated Democrats and Republicans have equally wrong knowledge about what people on the other side of the spectrum believe. College educated Republicans match their numbers. The outliers are college educated Democrats. They, by far, have the most distorted view of what right wing people ACTUALLY believe. It goes both ways of course, with conservatives dramatically underestimating the patriotism of liberals, etc.

When I lived in Arkansas, the voters simultaneously voted for a Republican governor and state house, AND a ballot initiative to significantly raise the state minimum wage, as well as a ballot initiative for medical marijuana.

The GOP politicians were all against these measures, but the voters approved them by large majorities.

The point I'm making is that the politicians on both sides aren't in step with the electorate, even if they are chosen by the electorate. People are voting for the lesser of two evils a lot more than we give them credit for.

mtanski · 5 years ago

Politicians are not in step with the general electorate, they are instep with party elites and primary votes. The primaries tend to select most "ideologically" aligned candidates and by the time you're in the general election the politicians on both sides are far away from the median voter.

Do you have a link for the old Intel bug? Here's one for a new Intel bug after just 1700 power-on hours on some enterprise-class SSDs that are still being sold today: https://www.intel.com/content/www/us/en/support/articles/000...

That's just 71 days of uptime and they hang. There are tens of thousands of these drives deployed as well.

mtanski · 6 years ago

Oh boy. We had somerhing like 5 our of 8 drives fail all at the same time. All of them were affected models bought at begining of summer and failed a couple months later.

It was a pretty maddening thing to debug and figure out where the issue was (servers, rack, drives, RAID do controllers). 2 different machines 2 and 3 drives. Week later we found the Intel bulletin about the issue.

Thank God for pgbackrest backups.

I could see overproduction of housing as a sign of the bubble. E.g. why are we suddenly giving out more loans?

mtanski · 7 years ago

New large generation (Millenials) coming to the housing market. Low interest rates driving folks to refinance. New housing is flat YoY if you look at "House Starts" statistics.

Who is starting, building these factories in Vietnam? Who is lending for capital projects and providing industrial expertise to local enterprises.

I'll give you one hint, the name of that country starts with a C.

My assumption is that someone with a score less than 700 probably had late payments on some of their debt.

mtanski · 7 years ago

FICO score for mortgages is not the same score as the modern FIDO score. The mortgage score is often what's called FICO v2 and the modern one is something like v10. They've even branded their different old versions as Insurance score, Auto score, Mortgage score and those industries kind of stick with it.

To illustrate why this matters. My modern FICO score is something like high 700s, low 800s (depending on credit data vendor). My V2 score is like 690.

How did that happen? Turns out when I moved out from my last house (5 years ago) and canceled my internet with Time Warner they failed to charge me $31 which was always set to auto-play. I actually settled 5 months after the move when TW sent me to collections. The shady collection agency promised to remove it off the record if I paid (they didn't). Instead, it shows up as a 5 year old, $31 late payment, paid in full.

How did I find out, while looking to refinance at these current rates. I'm getting this sorted out now. Both TransUnion and Experian got it fixed in a few business day.... fucking Equifax cannot get their shit together 3 weeks later.

For me it's a hassle, annoyance and wasted time. But as you can see it can impact real people and the score methodology is pretty dumb.

It's insane that a 5 year old, paid in full debt for $31, that's not even my fault drags my credit score down ~100 points (that's what it is once corrected) and prevents from getting a refi. Doesn't matter that all my other credit cards are always paid in full, no late payments on mortgage, car, insurance ... which all add up to several magnitudes more then $31 over the 5 years.

mtanski commented on As German Bund Yields Head to Zero, They Still Beat U.S. Treasuries bloomberg.com/opinion/art... · Posted by u/paulpauper

fauigerzigerk · 7 years ago

What makes this article a bit confusing is that they give an answer without making it clear what the question was.

Here's the missing question: Imagine you are a Eurozone pension fund or life insurer. You have to invest billions of euros very safely and eek out a return that is no less than inflation. How do you do that?

Inflation (HICP) was 1.73% in 2018. German Bunds, the safest euro denominated investment with sufficient volume, yield close to 0%. Now you look across the Atlantic and find that 10 year treasuries yield 2.63%.

The problem is that simply investing in treasuries wouldn't work because currency fluctuations would likely dominate any interest income. So you would need to hedge the currency.

The Bloomberg article is about why hedging the EUR/USD currency pair is currently too expensive for this idea to work.

It matters for European savers, including everyone who is paying into a defined contributions pension (e.g most workplace pensions). A significant chunk of those savings currently yields negative returns. The alternative is to take a lot more risk than you want to or are allowed to take.

mtanski · 7 years ago

So with EUR/USD hedge the assumption is that USD is going to drop or become more unstable in the future?

I don't think anyone assumes the opposite, that the EUR will rise as a result of strong economics performance.
