It's 8×100G yeah, but they also use two fiber pairs so four lanes go on each.

The QSFP-DD modules are also bigger (they stick out further from the slot) and have more power available, so that probably helps somewhat with engineering.

100G-LR4 is a technology that's on its way out, and this illustrates why. Muxing four 25G lanes is complex and costly and these days also unnecessary at 100G. 100G is going single lambda.

This is still the way to build 200G/400G/800G optics, though.

It’s a great test case for your “is this display landscape or portrait” functions

He's against it for sure, but AFAIK doesn't actually have a veto.

One of the Finnish news stories stated that as of now, the municipality is receiving only one fifth of the normal amount of waste heat they use for district heating. That sounds like they have shut a lot of things down to cope with the loss of power.

This is no longer necessary as of Podman 3.3 or so--there's a single Podman systemd unit that will launch all containers that have restart=always.

I have a Shenzhen-made 12V/20Ah LiFePo4 battery that has Bluetooth and iOS/Android apps for management. It, too, prompts for a password if you want to enter the "Pro Info" screen that shows per-cell voltages, BMS error states and so on. The password for this screen is "1234".

Feels like a move to limit liability to me. You "hacked" it, you're on your own.

Enterprise drives with PLP (power loss protection) are surprisingly affordable. I would absolutely choose them for workstation / home use.

The new Micron 7400 Pro M.2 960GB is $200, for example.

Sure, the published IOPS figures are nothing to write home about, but drives like these 1) hit their numbers every time, in every condition, and 2) can just skip flushes altogether, making them much faster in uses where data integrity is important (and flushes would otherwise be issued).

For just the fuel, yeah, but the expendable second stage adds a lot of impact.

1) The JWST is not in the shadow of the Earth. It’s solar powered.

2) It didn’t cost 9,000,000 dollars to build. That’s off by 1000x.

The Mac mini itself is not the only hardware cost for AWS here, though: I wouldn't be surprised if their Thunderbolt Nitro hardware cost just as much each. It has to be a very low volume device (relative to other things AWS does).

Who's "they" here? Remember, Bitfinex == Tether

The Wikipedia entry you linked to estimates 2021 internet traffic at 276 EB/month. That’s an average 839,625 gigabits per second. So 60 Gbps is one 14,000th of that.

Of course, one figure was about capacity and the other about actual traffic, but still.

Right. Dual stack IPv4 + IPv6 is strictly worse for reliability than plain IPv4 because both stacks need to work perfectly or you'll encounter issues. In that sense it provides the opposite of redundancy.

Happy Eyeballs (RFC 8305) is the typically touted solution, but even that doesn't help in the scenario you describe: IPv6 connectivity wasn't broken.

The problem is simply that we now have twice as many things that can go wrong and no plausible route away from dual stack in sight.

Netbox is awesome and I have just started to plan some automations to use its data (I currently just use the GUI).

However, if I use it as a source of truth for what is essentially config management, it would be replacing something that's currently running on top of git and GitHub.

I'm not sure I'm willing to lose version history, easy reverts, the pull request mechanism etc for this critical data. How have you dealt with this?

These details about the proprietary "SmartScreen" were really useful.

We have been sending login code emails via AWS SES and have had a lot of issues with Hotmail/Outlook.com not delivering them.

My takeaways: 1) There's a risk that a shared IP system like AWS SES will get blocked by SmartScreen based on emails someone else is sending. 2) We really should look at the contents of our (trivial) transactional emails, too.

Over the last year or so the company I run moved some content delivery workloads from a CDN onto our own network. So now we have something like 100Gbit/s of total external bandwidth.

The next thought in my addled brain is that since we only really use the egress side of it, perhaps some of our neighbors would enjoy affordable 10G internet access…

Sounds like the parties need each other, then. Could it be that economic links promote peace and stability?

You absolutely should check the MX records, though. It’s easy and catches tons of typos. I was floored by the difference when I implemented this as pre-check before a Stripe Checkout form.

What audits? The point is that there hasn’t been anything like an actual audit.

Yeah, that doesn't sound like my experience at all (which is limited to this one place). If anything, the burgers I like are less dry and less chewy than the beef-based competition.

Bun2Bun in Helsinki, Finland

The local burger joint closest to my house is 100% vegan and uses Beyond patties. It’s also, in my opinion, the best burger in town.

I’m a carnivore and would definitely notice the difference in a Pepsi challenge of the patties themselves, but the overall taste and presentation make this place pull ahead of all the meat-based alternatives.

I feel like we’ve crossed a threshold. This was literal sci-fi just a couple of years ago.

Thank you very much for this! One small thing I noticed: the curl examples on the v6 page call the v4 version.

With the disclaimer that I know nothing about this: doesn't the M1 have a separate "Neural Engine" for this? So it's using neither the CPU nor the GPU cores for TensorFlow?

The retail box came with a replica of Henry Jones’s grail diary. That was mind blowing for a ten-year-old who had just seen the movie. All in all still one of my fondest gaming memories.

> Probably because offering the smallest number of hardware models is more important to them than covering the whole market.

This is in the institutional DNA of Apple because it saved the company in the late nineties. Steve Jobs famously came in and canned dozens of Mac models, arguing that only four were needed: A pro desktop and a consumer desktop, a pro laptop and a consumer laptop. And that was that.

Apple is, what, a hundred times bigger today, but I don’t think the product design side of the company has really scaled up as much. I think they could afford to expand a bit.

I was looking at getting the Xeon-based NUC recently and one of the reasons I decided against it was that ECC SO-DIMMs seem to be a really marginal product. If you want ECC, something that takes full-size DIMMs seems much easier to buy memory for.

I've always wondered whether payloads weren't super-expensive precisely because the launches were, too.

I mean, if you are spending hundreds of millions to launch something, that something better work once up there, right? So you spend 20 years engineering a "perfect" payload, the costs do what they always do, and now you have a billion-dollar payload.

But if a launch was $2M and bookable with a month's lead time, you'd just de-risk the whole thing by having a simple-to-build, likely-to-work payload. Or ten.

(This might not apply to something like the JWST specifically, since even a terrestial mirror of that size is a huge challenge. But I bet a lot of other kinds of science payloads will be built very differently a decade from now.)

It doesn't have a ton of games, but if it has the games you're interested in, why not? I just ordered the Premiere bundle (to get 4K) and expect to play Red Dead Redeption 2, Jedi Fallen Order and The Elder Scrolls Online. They don't have much else that interests me at the moment, but so what? It's only $99.
