idoh··on Deep learning on electronic medical records is doomed to fail
In some situations yes, in others, if they read a 5.5 or a 6, then they will pick the one that fits.
idoh··on Deep learning on electronic medical records is doomed to fail
I happen to know a lot of doctors, including, as an example, an OBGYN. As it was explained to me, for vaginal births:

- at some point someone, without evidence, speculated that cervix dilation should proceed along some curve

- cervix dilation is actually measured by hand - literally inserting fingers and having the doctor practice "so many fingers = so many centimeters". There's plastic sheets with holes in them so they can practice measuring the size of holes with fingers.

- the OBGYN knows that the cervix dilation curve should look like, and kinda sorta maps their hand readings to what it should look like

- the OBGYN has a general sense as to how labor is going, and will game the cervix dilation stats to match their expectation, e.g. if labor is going well but the cervix hasn't dilated then they'll kinda sorta report progress anyway

Anyway, given the above it seems like the data around cervix dilation is suspect - the measurements are fitted to what the curve should look like, and then the data matches the curve, and that makes people more confident in the curve, and so on.

The point is, can you really apply ML to the EMR of cervix dilation? Does it make sense, could you really draw conclusions from this?

idoh··on Ask HN: When did computers get 'fast enough' for you?
A couple months ago I took on a project that involved working with coda, figma, with a company on the google productivity stack (gmail, meet, gcal), and the workload (mainly ram requirements) really crushed my computer. I had to get a new one, and maxed out the ram, and now I’m fine.

So I’d add web-based or electron-based apps to your “unless” list.

idoh··on Peter Thiel backs conservative dating app The Right Stuff
This is interesting, I wonder how the trend will play out. I remember the days when there would be apps like, "It's uber, but for lawn care / hair cuts / etc ...".

Now we are heading into a future where you'd say "It's like Tinder, but for Republicans / some group / some other group".

Is this bad? I have no idea. It seems like it might solve a real problem. I live in San Francisco, and for science I've asked some of my friends questions like "Would you date a Republican?" or "Can you be a good person and vote for candidate X/Y/Z?", and the responses, well, let's just say that it is not favorable.

idoh··on Meta shares drop 20% on Q4 earnings miss, weak outlook
Agreed. I was looking at them even before this dip. They are valued so low that even if they simply maintain current earnings relative to inflation they are an OK investment.
idoh··on Who Uses To-Do Lists?
It’s just definitional at this point - I’d say that a text file counts as a to do list.
idoh··on Best Pens for 2022: Gel, Ballpoint, Rollerball, and Fountain Pens
I saw that too. Who knows where the risk is from? In CA they have really strict rules around cancer labels so basically everything and every plance has them now.
idoh··on Best Pens for 2022: Gel, Ballpoint, Rollerball, and Fountain Pens
I’ve spent way too much money on fountain pens, and these are the ones I like the best: https://www.muji.us/products/aluminum-fountain-pen-e5a2 - less than $16 bucks too. Only Muji sells them so you won’t find them on the list here. But do buy ink and paper from jet pens.
idoh··on Ask HN: When is it acceptable to kill innocent beings?
Cats catch mice, not rats. You’d need some terrier dogs to clean this up.
idoh··on Why Lisp?
Quick question while we are all talking about lisps - any recommendations for a scheme-based web development repl? I’ve tried Racket and their framework, and while the documentation is great the one thing I really miss is that you have to do restarts every time you make an update.
idoh··on How credit cards make money
I saw this happening in Woodside CA (very much in the SF Bay Area) less than a year ago.
idoh··on Daylight saving time is 'not helpful' and has 'no upsides,' experts say
Adding to the pile of annoyances with DST - I’m now working at a fully remote company with employees spread across the US and the EU. The switch to DST is not synced between Europe and North America, which cause all types of scheduling havoc. Some meeting times switch, some do not. A totally avoidable mess.
idoh··on Facebook Faces a Public Relations Crisis. What About a Legal One?
You sue the person who made the post.
idoh··on California ports among world’s least efficient, ranking shows
Add another vote here. Are shipping containers in the top ten list of innovations for the 20th century? My vote is yes.
idoh··on Southwest new CEO denies walk-off rumors, defends pilots amid schedule meltdown
I’ve lost faith, it’s too late for that. Reuters and AP seem to play it straight. NPR I’d say is somewhat biased, not really at the facts level but in the way stories are framed. NYT is a hopeless lost cause. WaPo, I have no opinion on, I don’t really read them much.
idoh··on Southwest new CEO denies walk-off rumors, defends pilots amid schedule meltdown
It’s the spin, the contrast between what’s on the screen and the commentary about it. It causes me to lose faith in CNN as an unbiased source. Doesn’t apply to all MSM, but it’s a data point.
idoh··on Southwest new CEO denies walk-off rumors, defends pilots amid schedule meltdown
The journalist is literally standing in front of a burning building: https://youtu.be/igzNAzcXNBA

It’s totally fair to lose faith after seeing that.

idoh··on Will CircleCI make big $s?
Circle is on a usage based model, so the billing happens on a per job basis, and is based on minutes and compute type. Whether that translates into big returns or not depends on what you think the future of CI/CD looks like.
idoh··on Ask HN: What is your strongest contrarian opinion?
I could go on for days …

A - The majority of data science insights is kinda useless for guiding software product direction. Much better to have a well defined strategy and just execute on that, tradeoffs and all. I have to engage in the game because that’s what my boss expects.

B - In 100 years we are going to look back at pet ownership with disdain, especially cats, because how could we keep these animals in an environment that’s so restrictive if they are indoors, and how could we unleash them on the ecology if they are outdoors?

C - If you want to help the poor, and save money on prison expenses, then funding public defenders is really the way to go.

D - I love the US and what it stands for, but if there hadn’t been a revolution then no big deal, we’d probably be in the same place more or less.

E - Govermentment intervention didn’t solve the great depression, it made it worse.

I hold these all equally strongly.

idoh··on Justin Trudeau Vows Two-Year Ban on Foreign Home Buyers in Canada Election
It’s so crazy, the government just has to get out of the way of developers and then the problem will just sort of solve itself. We are sitting on the biggest economic opportunity thinkable because there is 30+ years of pent up construction demand. Simply letting that happen would unlock so much prosperity for decades.
idoh··on In 2009, Two Nuclear Submarines Collided Under the Sea (2016)
How would the proximity sensors work? The can’t go active sonar…
idoh··on Unifying iPadOS and macOS
You can just remote into a terminal if you want a CLI from an iPad.
idoh··on Tech companies probably won't return to offices in September
What’s your prediction around schools? Vaccination rates are much lower, many kids aren’t eligible for vaccines, and it is a bit of a hot house environment with lots of children packed into a small area. So does school return too? Just curious what the thinking is here.
idoh··on Ask HN: What is your “sales stack”?
What briefcase is better than a Halliburton?
idoh··on Woodsat: A Space Agency Will Launch a Tiny, Wooden Satellite
Wood has been in space before, see this link: https://space.stackexchange.com/questions/18856/puzzler-whic...

Apparently, balsa wood makes a good heat shield.

idoh··on Ask HN: Getting Laser Eye Surgery?
Problems with contacts causing infections.
idoh··on Ask HN: Getting Laser Eye Surgery?
I had a coworker who had lasik. About a year later, she got a paper cut on her cornea, (for real, she took a piece of paper off of a copy machine and it nicked her eyeball) across the lasik flap. It was extremely painful, messed up her vision for maybe a month, had to have eye surgery to fix it. It sounded horrific, but I asked her later and she has no regrets on getting lasik.

I have a cousin who is an opthamologist and he is totally against any laser surgery or even contacts, and the same with other opthamologists as well. He says to just wear glasses.

idoh··on Abolish High School (2015)
Let's not abolish it, but let's provide some alternatives. If you can demonstrate some proficiency across the three Rs, then why does it matter if you go to high school or not?
idoh··on Ask HN: Is there a case for small / medium data
Yes, there are huge opportunities for small / medium data. Maybe 90%+ data problems are in the small size range. The biggest pain point is converting the insights from the analysis into an actionable plan that actually improves things.

Thinking this through, the main pain point I've experienced is convincing people to act on the data, follow through, and connect changes in product (however defined) into changes in the metrics.

idoh··on Ask HN: Does University Choice Matter?
It matters, but choice of major and taking advantage of opportunities matter more. After your first job, for most career tracks, nobody asks what your school / GPA was.
