> I feel that supercomputers are good at one thing: if you need to make your country's flagship submarine about 10% faster/quieter than the competition.

Or doing Numerical Weather Prediction. :-)

But seriously, as a cluster sysadmin, the “128 jobs, followed by post-processing” is great for me, because it lets those separate jobs be scheduled as soon as resources are available.

> expensive resources with little support

Unfortunately, there isn’t as much funding available in places for user training and consultation. Good writing & education is a skill, and folks aren’t always interested in a job that has is term-limited, or whose future is otherwise unclear.

More context: This is related to today's release of the Spring Top 500 list (https://news.ycombinator.com/item?id=40346788). Aurora rated 1,012.00 PetaFLOPS/second Rmax, and is in 2nd place, behind Frontier.

In the November 2023 list, Aurora was also in second place, with an Rmax of 585.34 PetaFLOPS/second.

See https://www.top500.org/system/180183/ for the specs on Aurora, and https://www.top500.org/system/180047/ for the specs on Frontier.

See https://www.top500.org/project/top500_description/ and https://www.top500.org/project/linpack/ for a description of Rmax and the LINPACK benchmark, by which supercomputers are generally ranked. The Top 500 list only includes supercomputers that are able to run the LINPACK benchmark, and where the owner is willing to publish the results.

The jump in Aurora's Rmax scope is explained by Aurora's difficult birth. https://morethanmoore.substack.com/p/5-years-late-only-2 (published when the November 2023 list came out) has a good explanation of what's been going on.

Stanford University IT | Stanford, CA (next to Palo Alto) or Redwood City, CA | Full-time | Three positions | ONSITE (2 positions) or HYBRID/REMOTE (1 position)

Stanford University IT (https://uit.stanford.edu) provides a large number of IT-related services. We provide contract desktop support for labs and departments. We run the campus' academic/administrative, residential, research, and related networks. We provide Stanford's analog and VoIP telephone service, along with related services (operator services, code calls, IR menus, call recording). We provide Stanford Login (SAML/OIDC), the Stanford Directory (LDAP), Active Directory, RADIUS, O365 & Google & Zoom integration, email routing (SMTP/Proofpoint), Kerberos, cloud integration, and more.

Here are 3 positions to consider:

• DevOps Engineer: This is a HYBRID or REMOTE position. If you choose to be HYBRID, you'll be based in our Redwood City campus. You'll be part of the Authentication and Collaboration (ACS) group: From the list of services I mentioned at the top, the ACS group handles everything from "Stanford Login" to "and more". You'll find a good amount of Perl (our preferred language from back in the day), but also a lot of Python and k8s (either on-prem k8s or GKE, with a bit of EKS). More info: http://phxc1b.rfer.us/STANFORDdIwQM7

• Data Center Engineer (2 positions): You'll either be based at our primary research data center in Menlo Park (on the SLAC campus), or our enterprise data center (on the Stanford campus). The Menlo Park position only focuses on our research data center, but has broader responsibilities: It includes everything from racking and cabling to maintaining and troubleshooting power distribution (415v Starline bus), UPS (spinning-mass), generators, VFDs, air handlers, chillers, PLCs, and the like. The Stanford position focuses just on facilities (not racking/cabling), but has a more facilities to care for on campus. More info: http://phxc1b.rfer.us/STANFORDOqLQM9 (Menlo Park) and http://phxc1b.rfer.us/STANFORDAneQMA (Stanford)

If you don't already live in the Bay Area, we provide a relocation incentive. Depending on where you live, we provide free transit passes. Unfortunately, if you don't commute, you will have to pay for parking for the days you're on-site (except in Menlo Park). There is some on-call around the holidays. We get a 403(b) match, good healthcare, and 30+ days off per year (holidays + vacation). All Benefits are all publicly documented at https://cardinalatwork.stanford.edu/benefits-rewards.

If you have questions, feel free to reply here or email me (the info is in my profile)!

You might not get the price-benefits you expect.

If the only remaining allowed use for R-12 is in inhalers, the manufacturing volume might be so low that you end up in a similar situation to today: Fewer manufacturers (likely just one), higher prices, and supply-chain issues.

Folks who have been here long enough get the option to “Flag” a submission as being against HN Guidelines. But folks often flag something that they disagree with, or do not like.

Some folks also have the ability to “Vouch” a submission, to counteract the effects of flagging, but enough flags can override the vouches.

Posting your own work is OK. My guess is, some people did not think it was real. You can always email the moderators (hn@ycombinator.com) to ask. Do not be scared or shy.

I thought it was a good post. I hope this does not scare you away.

Reminds me a bit of a coworker who was here for maybe a month. He was hired into a position to support a particular group. Once he had seen how the group worked, and how they would treat him, he quit.

To be clear, he didn’t ghost us: He talked with his manager, and left the same day, as is his right in a right-to-work state.

He was probably in his early- to mid-30s; he said he had enough saved to last him through a job search, and I didn't doubt him.

Please clarify something for me, about major US airlines having 15 or 16 age limits.

Per https://www.united.com/en/us/fly/travel/accessibility-and-as..., it seems like they’ll accept unaccompanied minors potentially as young as 5.

Take something like work boots as an example: You might buy a $300 pair of Red Wing work boots that’ll last effectively forever. Someone who can’t afford that might buy a $100 pair of work boots from Walmart, which will need replacing more often.

So, in the category of Work Boots, you are indeed spending less.

The railroad is a good idea, but the concerns on throughput are real. If it’s a single-track railroad, your consist length (at least in one direction) will be limited by the length of sidings. Every rail car heading east will inevitably head west (to pick up containers).

It’s a big operation, putting together a new container-oriented freight railroad, and I hope it goes well!

Are you referring to Philips Respironics devices and their sound-dampening foam? You can get a CPAP from ResMed (a different company) instead, which was not affected.

The tl;dr: If your toothpaste contains Flouride, it needs to stay on your teeth for 20-30 minutes in order to work properly. If you don't want to do that—or you don't have a toothpaste containing Flouride—you can followup the brushing with a Flouride-containing mouthwash, which you do not wash out.

This is what I do. I use a mouthwash with Flouride, and don't rinse my mouth for ~30 minutes after using it.

This reminds me of a change that my dentist's office made a few years ago: Apparently dental insurance (at least my plan) has added coverage for a Flouride treatment with every office visit, so they have me do a Flouride rinse—probably with a higher-concentration rinse—at the end of each visit.

I know I’ve brought this up before, but I can’t remember exactly where.

It would be nice if DHCP could provide the current time as one of the pieces of information it provides with a lease. If you’re already trusting it for your IP address, you might as well trust it with the current UTC time: The current 64-bit timestamp would be enough to get timestamp-sensitive things working.

The University of Minnesota has advice for you!

The tl;dr:

• Having a fridge thermometer & a freezer thermometer are good.

• A full freezer, kept closed, can hold temperature for ≤48 hours. A half-full freezer, ≤24 hours. Fill your freezer. Ice (to fill up empty space) is your friend. You can make it, or buy it from the store.

• The fridge part, kept closed, can hold temperatures for ≤4 hours. Block ice can help extend that time. A fridge thermometer can be used (after power is back) to check if the temperature exceeded 40° F.

Block ice? It's exactly that, ice in the form of a large block. https://elitecooler.com/blogs/news/cooler-use-get-the-best-i... has more info on using it for keeping things cool.

Ah, so they’re not permanent! I always assumed they were.

Similarly, you’ll see occasional Liquid Nitrogen tanks around: https://youtu.be/juZqGU9iuq0

For the captive-portal detection part, there’s an RFC covering it: The network provider can tell the device where to send the user, and can provide an endpoint to get info like how long is left on the session.

Apple has a page on it, here: https://developer.apple.com/news/?id=q78sq5rv

This is concerning. The possibility that a company’s livelihood could disappear, only rebuildable by reassembling the bits found on developers’ local Git clones. And then having to spin up new Git infra, rebuild all the pipelines, etc..

I'm able to access the Google Cloud Console, while I'm unable to access the AWS Console.

Can you provide more details on what you're seeing?

I don't think it's necessarily AWS.

I've got coworkers who are on campus, and can access AWS (and AWS-based sites) fine. Their connection to AWS is via the CENIC ISP, which peers directly to AWS.

Me, at home, on Comcast, I cannot connect to AWS-based sites, nor to the AWS console.

The full video title is too long to use as the submission title. It is: Why Are Emulators Legal? Dolphin vs. Nintendo, and the Fate of Emulation

Interesting! FYI, on iOS Safari, clicking the "Conditions" link just scrolls me to the top of the page.

I noticed this is getting downvoted; you might want to do a post specifically for this.

Sending virtual hugs to your coworker!

I enjoyed reading this! Take a problem, in a controlled environment, start with the simple implementation, iterate, and compare results.

I really recommend folks watch this, from a lawyer:

https://youtu.be/wROQUZDCIMI

“Why Are Emulators Legal? Dolphin vs. Nintendo, and the Fate of Dolphin Emulator”

"[VMware's End-User Computing Division's] flagship products include Horizon, a leading desktop and application Virtualization platform, and Workspace ONE, a marquee Unified Endpoint Management (“UEM”) platform for the enterprise, along with common platform services of data, identity and workflows."

VMware Horizon? Ugh, that's concerning.

(Horizon is VMware's thin-client / zero-client platform.)

From the Facebook post linked in the article:

> Are we so caught up in the past that that we do not embrace technology? Is recording with tape better than digital daws. Is taking a polaroid picture better than the newest tech phone? It's still about the music and lyrics and that's REAL!!!

That seems to me to be a false equivalence: Whether you use tape vs. a DAW, a Polaroid vs a phone, you're still putting in effort. I wonder what AI they used, and what their prompt was, and how much time they spent on it.

All that being said, reviewers are gonna review. An established group will be reviewed in the context of their previous works, and that includes the album cover.

It's more than just "hanging out for too long". You have to be clearly occupying the space, and you have to be improving it.

In California, "Adverse possession" requires a lot: You have to occupy a place continuously for 5 years, like how an owner would. You have to pay all taxes on the land for that time. You have to be clearly occupying the land, so it's obvious to all (including the owner). You have to be acting like you are the owner of the land: Getting & paying for electric, water, internet, trash pickup, etc..

So, there's a high bar that has to be met.

To be clear, the "brief" reference is this:

> Because of curl’s use of third party libraries for doing QUIC and HTTP/3, the report advises that there should be follow-up audits of the involved libraries. Fair proposal, but that is of course something that is beyond what we as a project can do.

Indeed, the next thing would be for the third-party libraries to go through a similar audit!

Ah, time for the obligatory Wendover video!
