rexer··on FDA says marijuana has a legitimate medicinal purpose
Yea! I thought along the same lines, but I wasn't sure how to write it out. If X is on a spectrum, and Y is removed, it's closer to not-Y.

Edit, eh your explanation probably explains it better anyway :)

rexer··on FDA says marijuana has a legitimate medicinal purpose
Native speaker here, this has kept me distracted on a couple long drives.

  “X is all but Y”

  Interpretation 1: X has moved so close to Y that it may as well be Y  
  -> X loosely equals Y   
  (I think this is the colloquial understanding)

  Interpretation 2: In the set that represents X, Y has been removed  
  -> X is not Y
Excuse the poor notation, I hope this is clear! The tldr is this confuses me too sometimes
rexer··on Webb and Hubble confirm Universe's expansion rate
This looks perfect, thank you!
rexer··on Webb and Hubble confirm Universe's expansion rate
Great comment! Maybe you can help me with a book recommendation?

I was recently looking for a book which was basically your comment, but more in depth and covered the last couple thousand years. I wanted a to read about the history of astronomy - yknow, what was the state of the art in, say, 1350 or whatever. If you know of anything, I’d be super interested!

rexer··on Wet-bulb temperature
Surely a cold shower helps? If it causes your body to trigger self-heating process, surely that’s proof your body has been cooled to less than dangerously high levels and the shower has provided at least temporary relief.
rexer··on Leo Tolstoy on why people drink (2014)
> Could you elaborate about not how you aren't really any more in control when sober?

Not the person you responded to, but I can give it a shot.

I think the crux is that you don't have as much control as you think you do, even when sober. Whether you realize it or not, you're still at the whims of yourself and environment: emotions, time of day, exhaustion, pressure. You can't think or analyze yourself out of that. So sure, you may take more risks when drinking, but so what? Do what feels right in the moment.*

* Y'know, within reason. Buying plane tickets = good, getting a forehead tattoo = bad.

> My aversion to alcohol largely comes from wanting my best judgement intact in order to better survive complex situations.

This really resonates with me, and it's something I'm actually try to minimize. I've been finding being present -- and not attempting to foresee and prepare for uncomfortable situations -- to be a much happier place to be. And should a scary situation arise, I trust my future self to handle it appropriately. Or he won't, and that's fine too!

rexer··on Are we going back to the cable days?
A couple months ago, prior to the latest season of Better Call Saul, I signed up for AMC+ to catch up on old episodes. I was very surprised to see _none_ were available to watch. Furthermore, there’s a banner warning now at the stop stating the latest season (now over) is only available until August 30th.

I’m not sure what happens after that, but the assumption that all released episodes will always be available is no longer true.

rexer··on Time isn’t simply just another dimension
Not quite, though, right? Because the magnitude of those two vectors is different: the magnitude of the latter one is 1.7. I agree with the rest of your statement.
rexer··on Can we fix bearer tokens?
Why not drop the beater token entirely and rely on mTLS for auth? There’s even space in the cert to put metadata that can be used for authorization.

..ah I suppose if you did that you’d need a certificate per site, and that many keys may not fit in most TPMs.

I suspect one of the big challenges here is interfacing with the OS for hardware backed key signing. Bearer tokens are easy because it’s all contained in the browser.

Another challenge is that it complicates federated auth. Now instead of just validating any token with one of a small number of keys, you must verify the client cert matches that specific user. Signing the client cert may mitigate this, though I’m not sure what issues that may cause.

Anyway, interesting idea! This problem is certainly worth some thought.

rexer··on Food is more expensive than it has been in decades
When was Stella 12oz? It’s been 11.2 as long as I can remember.
rexer··on Confessions of a Ransomware Negotiator
No. In that moment your biggest problem is that all your data is inaccessible. That you don’t have backups reduces options since it precludes that solution, but another one exists: pay the ransom.
rexer··on JWT Tokens are NOT safe
Could you expand on why 30min session validity after explicit logout is okay? I don’t mean to sound accusatory; I would like to understand your reasoning.
rexer··on How medicine discriminates against non-white people and women
Your comment and the one you replied to don't make sense to me. How can skin only differ in pigment, but it also require additional training to care for skin of different color?
rexer··on Most common mistakes during interviews
Can you expand on why you believe these sorts of interviews don't offer good signal? Having gone through a couple of these interview cycles, I felt the behavioral questions adequately demonstrated how I'd perform in similar situations.
rexer··on Why Understanding Beats Knowledge
It might help to think of a specific curve. An example would be a simple parabola: f(x) = x^2. At the bottom of the curve (x = 0), the slope (aka tangent, aka derivative) is 0, or a horizontal line.
rexer··on Trump to sign executive order on social media Thursday
Genuine question: what do you think of Twitter selectively applying their ToS to Trump?
rexer··on Ask HN: Is there anywhere as intellectually curious as kuro5hin used to be?
If that was an invitation to ask for an invite, consider this a request! My keybase is in my profile. Reddit continues to devolve, and I'm always looking for new online communities to replace it.
rexer··on Creating a Slack Writing Etiquette Guide for Your Workplace
By "everything there is a thread", do you mean there can be multiple topics (subchannels) per channel? Couldn't you achieve the same by namespacing Slack channel names?

First I've heard of Zulip, so perhaps I'm misunderstanding what you mean by thread.

rexer··on Ask HN: How do we stop the polarization/toxicicity filling the web?
The claim wasn't that they're harmless, but that they're easy targets.
rexer··on Sonos’ frantic flailing illustrates the stupidity of smart tech
That's a lot of speculation and FUD. There's nothing inherent about IoT that requires it to be reliant on remote services.
rexer··on “Customer support at Tesla is even worse than I claimed last time”
Using your analogy, it can be better for all involved to develop a single eight cylinder engine and sell it with two cylinders disabled for less to those that only need six cylinders.
rexer··on “Customer support at Tesla is even worse than I claimed last time”
Exactly. You can see this in Tesla with their 60 vs 75 model S. The battery is physically the same in both, but software limited (liftable via OTA) in the 60.
rexer··on “Customer support at Tesla is even worse than I claimed last time”
I never understood this. If you want the latest tech, you should be expected to pay your share of the the R&D/materials that went into creating it.
rexer··on Ask HN: Remote workers, what's your backup plan?
I had a longer response written out, but to simplify, I think the risk is if remote work ever becomes hyper-competitive, falls out of fashion, or otherwise not able to fit ones needs. I speculate that's far more likely to happen in the remote than local job marketplace.
rexer··on Stripe Atlas Vendor Leaked SSNs
I think you may have authentication and authorization swapped.
rexer··on Don’t Shy Away or Risk Cowardly Management
This is why discourse is so important, to be able to ask for clarification on the context and scope of the feedback.
rexer··on Storing 50M events per second in Elasticsearch
> This is a very common use-case(eg. logging), but it's surprising that Elastic has nothing to automate this.

You can set an index template to be used on new indices that match a pattern, which is a very common thing to do. It sounds like what they did was modify the template daily, which is less common IME. It's not clear why they had to manually create the index, though. That should happen automatically.

rexer··on Starship Update
Extra weight. If gravity is the only thing changed, mass would remain constant.
rexer··on DoNotPay's new service auto-cancels free trials
One of my credit cards (Citi) allows creating virtual credit card numbers. I've been hesitant to use them in this way, though, because I'm concerned it could affect my credit.

Does anyone know if legally you're on the hook for the paying the service provider? As technically they did provide the service, and you're "refusing" to pay for it. Presumably, if so, they could send the bill to collections and put a black mark on your credit.

rexer··on Uber Eats to Test Flying Food to Customers by Drone in San Diego
I live in an area exactly as you describe. While stuff might be technically walkable, it still could be 20+ minute walk each way to the "close" places I want to go.
