on: Memory is slow, Disk is fast – Part 1
Disk hardware may be faster relative to RAM, but if you're using typical serverless PaaS offerings to run a hosted application at modest operational scale, it's a heck of a lot cheaper to get a node with "normal" RAM and CPU, than it is to get decent IOPS. If you're a big iron company with big iron problems, you may need to think in different scaling terms, but for the SaaS hoi polloi the economics of hosting have somewhat preserved traditional notions of performance.

on: The Art of Finishing
I think it's worth differentiating between personal projects done to learn or just for interest, and those that are trying to accomplish something. If I do a project for myself to try things out and learn something I don't feel any pressure to finish the project. Once I've learned something or had some fun, who cares if it's "finished" or if anyone else will use it. On the other hand, sometimes I'll pick up something interesting that helps a friend or family member, or just that I need for myself, and there I'm pretty careful about scope. If I can't finish it in a couple weekends I'll look for the closest commercial solution unless it's a major once-in-a-decade passion project.

on: Love them or hate them, this couple reign in Russian literature
As someone with an English "bottom" as in bottom-lands surname, I appreciate the deliberate silliness of "Longbottom" while leaning into a very traditional British sounding name.

on: 1Password detects "suspicious activity" in its internal Okta account
FIDO2 wouldn't have helped the customers' accounts since valid session tokens were obtained. However, hardware tokens for the Okta customer service accounts may have blocked the threat actor's access depending on the (undisclosed) method of attack.

on: Supreme Court sides with Slack, putting direct listings in jeopardy
But it also seems likely that companies will decide to take advantage of the reduced liability (especially now it's confirmed and not just theorized) and investors will just price in the risk difference.

on: Regular Expressions make me feel like a powerful wizard: that's not a good thing
One benefit of regex that isn't mentioned in the article is that you can expect it to be available, at least the basics, in pretty much any programming, scripting, or even querying environment.

I looked up the snowman in several fonts and copied as best I could. Utter failure. If it can't find the snowman....

I'm not doing a CAT III. I'm saying the joke RNAV at the north pole using Rudolph should have been portrayed as a CAT III.

Thanks for sharing from a recent IRA pilot! I'm surprised they didn't do this as a CAT III ILS. A DA of 250' with Rudolph leaves a lot of margin for Santa to get snowed in.

on: How School Buses Became Yellow (2019)
Looking at the pantone color it appears more yellow to me. I have seen a lot of minor regional variation though, especially when weathering affects things, so they may be orangier in your area. You could always say they're yellange.

on: Does Company ‘X’ have an Azure Active Directory Tenant?
Even if they don't use Azure AD as their primary SSO you can often federate indirectly via Azure. For many large corporations, an auth against Azure redirects to Microsoft, then to whatever enterprise SAML2 service they're running, then back to Microsoft to pick up an OIDC token or SAML transformation, then back to your app. Instead of supporting however many SAML 2 providers with custom claim mappings you get Azure's reasonably straightforward token. You can also pick up Azure group membership (which many companies maintain or sync from on-prem AD) which is nice for mapping application roles.

on: What are you supposed to do with old clothes?
Children's clothing can get worn pretty hard too. Our stuff is definitely not in donation suitable condition by the time it's too small, although I suppose it might be different if we bought more or more expensive items.

on: Game Boy Wordle clone: How to compress 12972 five-letter words to 17871 bytes
I have designed task specific data structures/compression oriented around memory efficiency. In my experience this starts to crop up when datasets get big enough to trigger cost for performance sensitivity. This is especially true for SaaS offerings, where e.g. an ability to stay under the next RAM doubling can result in serious hosting savings.

on: Cocktail party ideas
I find it helpful to use a range of descriptors. A "simple" task is easy and can be done quickly. A "straightforward" task is easy but may be larger in scope. A "tricky" task needs study to determine where it falls. A "hard" task has known complexity and is just plain hard.

on: I Did the Math on My Town’s Cul-de-Sacs. Here's What I Found
A third way to make a low density neighborhood solvent is to decrease the cost of the infrastructure. We live in a low density neighborhood with right-of-ways along property lines, but no sidewalks, curbs, or below-ground storm drains. The roads are designed to discourage high speeds, and it's a pleasant walking environment, so the non-vehicular traffic along the roadside is higher than most suburban neighborhoods.

You can't hold your breath in a low pressure environment. Also the low partial pressure of oxygen causes it to diffuse out of your blood instead of in. Even people who can hold their breath for a couple minutes under normal circumstances will have severe hypoxia impairment in less than a minute above 30K feet.

on: Ask HN: I'm an incoming freshman to college for a CS major, what should I know?
On the flip side, if a degree program is at a liberal arts institution it may have plenty of humanities builtin and you may want to add a few extra CS courses to round things out.
