He mentions that he's running it in an air-conditioned studio, so presumably if the unit's datasheet lists an environmental range warmer than that, it has plenty of cooling headroom in this environment.

The last rubidium oscillator I played with, had to heat the vapor cell within the physics package, but then prevent that from overheating the rest of the unit, so it specified mounting to a heatsink. There was no heatsink recommendation given, just a certain package temperature as reported by sensor value X in the diagnostic data page. Get below that and you're golden. Get too much below that and you're wasting extra energy in the heater. Which is harmless, it just drives power consumption up.

So depending on how the unit's thermals work out, a slightly less aggressive fan may end up being mildly beneficial.

I converted from residential-class to business-class cable a few years ago. In both cases, I had routable IPv4 addresses.

I was just looking at flipping back, but now it seems the default for new resi accounts is CGNAT. They say they'll give me a real IP upon request at no additional charge, but it's anyone's guess how long that holds out.

They don't do IPv6 at all.

Yeah, that's probably part of it. Some do have explosion vents in the top of the container.

It'd just be impressive to see a giant wall of battery. A bunch of little batteries camping in a field doesn't play the same visually. Ah well.

One reason they report in MW instead of MWh, is that grid operators primarily spec systems by their continuous MW, and only secondarily mention their cumulative MWh. So that's the way they talk about them, and reporters just mimic that. Both are important, but the top-line number is MW, for sure.

One reason for this is that for a lot of grid-support functions, instantaneous or short-term power is vastly more important than long-term energy capacity. The other reason is that traditional generation is only sized by MW; you just keep pouring fuel into it forever, so the notion of MWh doesn't even enter the picture. They're not even thinking in those terms.

You and I, as battery natives, think about it the other way around. But we're not grid operators.

I've always wondered why they don't stack them in deployment -- the containers are obviously fine with it! -- but I guess land is cheap enough not to bother.

Horizontally they need plenty of room for airflow, as each container has some HVAC-or-whatever module on the side. But vertically...

For years, I've said that if there's a "call for quote" where I expect an "add to cart", I'm gone, instantly. I will buy somewhere else.

Now there's a login before I can even figure out if it's a quote or a cart.

Byeeee.

Oh yeah. I toss the sheets in the washer the moment I get up on the day I'm leaving, and transfer them to the dryer (or clothesline) on my way out the door. So there's no chance of the cleaning crew "cleaning" the bed by just making it. As a favor to the next renter.

When I walk into a bar, I always ask the bartender for negative zero beers, just to check the place out, before placing my actual order.

I have not yet been accused of arson, but it's only a matter of time.

"Gig" implies paid. Nah. Just for laughs. Because hackerspace.

Some years back, I helped build a Twinkie cannon, which was mounted in the front of a Twinkie-decorated car, built on a dune buggy chassis. We had to remove the roll cage to fit the fluffy cake body (made of airbrushed yellow fiberglass insulation), so we made sure to drive it quite slowly, but it was a beast underneath if you wanted it to be. (I once drag-raced a pizza driver, and only afterward noticed the cop on the next streetcorner. Luckily it's hard to write a ticket while doubled-over laughing.)

The CO2-powered cannon was capable of way more power than cellophane-wrapped Twinkies can handle. Dial the regulator up past halfway, and they'd just shred on exiting the barrel, splattering anyone near the front of the car with sticky creamy filling and cake crumbs. That was both messy, and disappointing to folks down-range who'd been hoping to catch a snack. (And it immediately summoned a cleanup crew of seagulls, who then wanted more...)

So we learned to keep it modest, and developed a decent sense of pressure vs range. The car geometry allowed only limited variation of the barrel angle, so it wasn't a full-on GORILLA.BAS experience, but it was pretty close.

Culinary ballistics keeps you young. I highly encourage it.

Exactly. "Responding to pings" is not the same as "letting me get work done".

If I had a nickel for every solid-green status page I shook my fist at while the actual site faceplanted on every request...

Is Broadcom not obligated to issue a CVE for a legitimate vulnerability?

Since they wouldn't share the contents of their notification to their customers, we don't know how clearly those customers (router makers) were notified. But having a CVE and detection signatures would get this vuln into all the usual scanning and reporting channels, which is another route the customers might (should!) be paying attention to.

Also, I don't know how laws over there work, but there might be legal requirements to patch things once they're known, where "known" is probably defined by "has a CVE issued". So by refusing to issue one, Broadcom is blocking that process.

How is that blameless?

The article estimates the number of these routers in the author's home country (Belgium), but the vulnerability would exist in units sold worldwide, no? Seems to me that their estimates of affected units are a couple orders of magnitude low.
