cure··on Hetzner announcement: Price changes for servers ordered via the Server Auction
Yeah, new hardware can be wildly more energy efficient than older systems.
cure··on More Americans are saying they’re ‘vaxxed and done’
Sigh. This is wrong, and I wonder why it is so hard to understand that it's all about probabilities.

Being unmasked for 50% (?) of the time (while eating, say) you are in an enclosed space is obviously less risky than being unmasked 100% of the time.

cure··on Should you use Let's Encrypt for internal hostnames?
> OK, so you decide to have an internal DNS - now the whole world knows you have doorbell-model-xyz.myhome.example.com!

Uhm, or you use split horizon DNS? Who in their right mind would leak all their internal DNS names into a public DNS zone?

cure··on Motorists have been stranded on a major interstate in Virginia since last night
Indeed! That's a good point. If it uses a linear regulator, I guess the thing would produce quite a bit of heat when drawing power from the USB ports - the extra energy would just be converted into heat.
cure··on Motorists have been stranded on a major interstate in Virginia since last night
Mind you that's 3100mAh at 12V. That's roughly 7400mAh at 5V (USB voltage).
cure··on Motorists have been stranded on a major interstate in Virginia since last night
I have actually used this thing several times to jump a car. It works great.
cure··on Motorists have been stranded on a major interstate in Virginia since last night
Good advice. I also keep a "Portable Car Jump Starter" in the trunk. These days they are basically big batteries (mine is ~3100mAh at 12V apparently) and they come with USB plugs and a built-in flashlight... Handy if you need to recharge your phone in a pinch.
cure··on Leave Scrum to rugby, I like getting stuff done (2020)
I guess you're not a developer. JIRA is incredibly convoluted and backwards from a development perspective, because it was built for a different audience (product? sales? I'm not sure).

Just try to find a diff in a JIRA "issue". It's crazy how many clicks that takes.

cure··on Facebook says it was wrong to ban Canadian MP’s Christmas message
Maybe the FB algorithm takes past posts into account? His account has probably been a fountain of misinformation and hate, and now he sends one innocuous message and is surprised it gets blocked. Yawn.
cure··on Germany is closing half of its reactors before the end of the year
> I don't see how wind and solar don't make sense.

Wind and solar make total sense. All we need to do is overbuild wind/solar generation + invest in energy storage capacity. This can be done relatively quickly, certainly much more quickly than building new nuclear plants.

cure··on Germany is closing half of its reactors before the end of the year
> Please correct me if I'm wrong but my understanding is that nuclear doesn't ramp up/down very well either.

Correct. Nuclear reactors can't be turned on/off quickly. They are suitable to handle the base load, in other words, but can't be used as peakers.

> Wind and solar don't even make sense for Germany given their climate/geography.

Uhm, respectfully, that is a load of nonsense. Cf. https://en.wikipedia.org/wiki/Renewable_energy_in_Germany

> Germany should ditch the green and use its amazing engineering to build better nuclear reactors, IMO.

Well, if they start that plan today, it may be done in 30 years. Which is way, way, way too late.

Imo, the more sensible path here is to keep the existing nuclear plants running, decommission the that awful lignite power generation asap, while building out energy storage capacity (grid scale batteries - there are many kinds of approaches, e.g. electrical batteries, reservoir storage and some seriously weird ones involving lots of blocks of concrete). That could be done in the space of a decade.

Any new nuclear plants would not even be out of the design stage in 10 years.

cure··on My values, howled into the wind
Maybe that person is called "rational, open minded, generally good-hearted" ?
cure··on Ask HN: My client want an agent on my laptop. Is this the new normal?
Since this 'Drata' thing is intended to keep employees/contractor computers in check with policy requirements, runs as (equivalent of) root, and auto-updates, I assume it must be:

* completely open source

* have gone through security audits with public reports, and a favorable outcome

* have reproducable and verifiable builds, and those are the only ones distributed, and the end user can easily verify that their binary copy is an official build?

Right?

Because if not, aren't you just adding another attack vector onto all your employee/contractor laptops when you use 'Drata' to check a policy box on your SOC2 application?

[edit: formatting bullet list]

cure··on Ask HN: My client want an agent on my laptop. Is this the new normal?
> Guessing it is privileged and self-updating.

And closed source, of course. Must be totally free of bugs too, like all software.

cure··on From Node to Ruby on Rails
And at least 20 different tools built over the years, none of which are a complete solution afaik. Cf. https://chadsmith.dev/python-packaging/.
cure··on From Node to Ruby on Rails
Well summarized, grandparent!

> On the Python side I think the movement has started to fix the packaging mess. It's going to take a while me thinks.

I hope you are right, but ... this is the pattern: every year or two someone decides to fix it, goes about 80% of the way to a complete solution (which is maybe 50% of the effort, of course), that becomes 'the thing to use'. But then it is abandoned because that last 20% of functionality is a lot of work, and someone else comes up with a new shiny thing, and the cycle starts again.

Not holding my breath, in other words.

cure··on From Node to Ruby on Rails
You forgot a very important one

- Python package management (a raging dumpster fire)

cure··on Carmen Ortiz Has Blood on Her Hands (2013)
> The far right and far left (of which Matt Bruenig is decidedly a part of)

Matt Bruenig is not far left, cf. https://en.wikipedia.org/wiki/People%27s_Policy_Project, he's a democratic-socialist, maybe at most a socialist.

Far left is quite something else! Cf. https://en.wikipedia.org/wiki/Far-left_politics.

cure··on Intel seems awfully scared of Graviton2. Why pay for this ad on Google?
Right. But even then it does not become that much worse.

Just tell Go to use the appropriate cross compilation chain for the C bits, e.g. `apt install gcc-aarch64-linux-gnu` and set the `CC=aarch64-linux-gnu-gcc` environment variable to compile for arm64. Compilation becomes a bit slower, but it's still manageable.

It's that easy thanks to the foundations laid by the distribution that ships a solid cross-compiler setup (in this example, thank you Debian!) and of course the brilliance of the Go design and toolchain.

cure··on Widespread exploitation of critical remote code execution in Apache Log4j
Not really? Your link shows that the log4j is not used in core Jenkins.

Moreover, they provided a nice test to see, on a particular installation, if any plugins are affected. Judging by the provided link to their issue tracker (https://issues.jenkins.io/browse/JENKINS-67361?jql=labels%20...), there only seem to be a handful of plugins affected, and none appear to be super widely used.

They are responding really well to this, by the way. That blog post is clear and useful information is being added. Kudos to the Jenkins team!

cure··on This website has 81% battery power remaining
Riiiiight.

I'm sure it has nothing to do with a complete lack of competition (cf. how in communities where Google Fiber showed up, the incumbents were suddenly quite capable of getting gigabit fiber to households, and for a price that was competitive with Google Fiber, and a fraction of the price they were charging for inferior service before Google Fiber's arrival).

I'm sure it also has nothing to do with the billions upon billions of subsidies AT&T and Verizon have received to build out broadband and make it available everywhere, which they pocketed and then didn't deliver on. Cf. https://www.huffpost.com/entry/the-book-of-broken-promis_b_5...

If you really want to blame it on government, do it the right way: the government has not been keeping AT&T and the other giant telcos accountable for effectively stealing all those subsidies, and it has not enforced competition at the local level. Regulatory capture, and all that.

cure··on Pixel prevented me from calling 911
Not last time I tried. That flow (i.e. you are not part of/logged into an institutional Teams account) is completely broken. Teams makes you go create a free Microsoft account, which then doesn't work to log into Teams.
cure··on Lead poisoning among US children
> Also it's frustrating because I asked my pediatrician for blood lead test and they wouldn't do it as they said it's unnecessary. I am going to switch doctors and try to push harder at the next checkup. I've heard there is a finger prick test that's not very good and then a blood draw that's actually fairly good but of course more invasive.

Huh, yeah, sounds like you need a better pediatrician. That's not cool.

Several states in the Northeast also have mandatory testing for lead levels for young children.

cure··on Pfizer and Biontech provide update on Omicron variant
According to this source https://www.statnews.com/2021/02/02/comparing-the-covid-19-v... the original Pfizer dose was 30 micrograms of vaccine, while Moderna's was 100 micrograms.

If that is correct, then Moderna's booster would still be more vaccine (50 micrograms) than Pfizer's original dose.

Of course more is not necessarily better!

But any other nearby iPhone is...
cure··on Solar-driven water splitting at 13.8% solar-to-hydrogen efficiency
> Electrical grids don't store energy. If you wanted to store just 10% of the U.S. electrical generation from summer to winter using lithium-ion batteries, it would cost roughly $42 trillion dollars. Yes, trillion.

Do you mean 10% of the generation on a typical summer day? Or 10% of the generation of an entire summer?

The problem with this kind of calculation is that battery technology (and cost) is very much a moving target.

LFP would probably be the better choice today. It's cheaper, safer, and can handle far more load cycles. That comes at a cost of a lower energy density, but that hardly matters for utility scale batteries. Tesla's megapacks use LFP already - https://cleantechnica.com/2021/05/11/tesla-transitions-to-lf....

Like you say, there are many other energy storage options like pumped hydro, compressed air, etc. My personal favorite is the train full of concrete that goes up and down a hill (https://interestingengineering.com/concrete-gravity-trains-m...).

cure··on Without parental leave I might be dead
I think your frame of reference may be a bit warped. What is an 'average' salary?

The median personal income in 2019 was $35,805 (cf. https://fred.stlouisfed.org/series/MEPAINUSA672N). I think you'd be hard pressed to live on that with a family of 3+ people.

And what about the 50% of people who have a personal income less than the median?

edit: that stat was for 2019, not 2020, my bad

cure··on “Losses caused by or resulting from a Cyber Incident are not covered”
This is not cyber insurance, so this isn't exactly surprising? There is separate insurance for Cyber.
cure··on EU Chatcontrol 2.0 [video]
It's not the parliament that is pushing this nonsense. It's the European Commission, which is not directly elected, that is the problem.
cure··on Toyota unveils its first all-electric car: the bZ4X
Applying Hanlon's razor...

I think it's just a case executive incompetence/severe tunnel vision: Toyota has been in hydrogen lala-land for a good long while now. Now they have some serious catching up to do.
