Is there not an official tool from AMD?

Qualcomm doesn't bother to upstream most of their SoCs. They maintain a fork of a specific Linux kernel version for a while and when they stop updating it or new version of Android requires newer kernel then updates for all devices based on that SoC end.

They have little experience producing code that is high enough quality it would be accepted into Linux kernel. They have even less experience maintaining it for an extended period of time.

Sodium gravimetric density is same. Volumetric is worse. Shipping containers generally cost by volume, but given how dense batteries are I suspect this won't matter.

I'd agree if you could stick them in the containers discharged, but you can't. This means that even safer chemistry like sodium battery is still hazardous cargo.

Unless you want to charge in negative temperatures

> However, this battery faces range limitations

Yes they are less dense but plentiful for typical passenger car (and not so much for full sized trucks or even "mid-sized" US SUVs).

> the issue of how to improve charging speed

I think CATL demonstrated 1MW charging on these already. Definitely shipping 500kW charging (tho best measure is still average km/hr).

> Solid-state batteries should be the next big thing

Sodium will (great cold weather performance and even better charge rates), but it's less (vol) dense and prices won't reach LFPs for another 10-15 years (unless you believe hype, not actual analysts).

The small handful of sodium batteries that are currently available retail all seem to have rather bad roundtrip efficiency compared to LFP and voltage drop starting at a high state of charge.

Also LFP prices dropped enough that shipping cost from China became a significant part of the price. This will be even more of a factor should the less energy dense sodium batteries ever reach the promised $30/kWh.

If you're going to go for a two year supply, it's probably better to just risk shipping it. You're not going to come home with that much without it getting confiscated, and you're way more likely to be searched individually than a typical package is.

With de minimis for US-bound packages suspended I suspect way more packages are inspected than used to be.

There are three career stages. First you're not qualified enough, then for a moment you're overqualified, and at last you're too old. The last stage occurs few decades before statutory retirement age.
c2h5oh · 3 months ago
Similar three stages are also at every job you have:

- you underperform while onboarding and rapidly learning to cover whatever skill gaps you discover

- you slowly go from doing OK to being overqualified, but it doesn't get reflected in compensation or title enough and your employer has little incentive to help you reach the next stage, because you are currently overperforming compared to your pay

- you are so much past your paygrade you quit and go to a company that will pay you what you will be worth after onboarding and learning to cover skill gaps

With everything that companies provided to earn long term employee loyalty being sacrificed to stock price employee growth through multiple roles in the same company has become more of an exception.

c2h5oh: that does sound sucky. Perhaps it mostly describes web development though? Other software fields take this stuff more seriously.

Unless you equate web development and SaaS then no. It's the same in education, finance and SaaS targeting Fortune 500 companies.

Depends upon the software.

I find valgrind easy on Linux and ktrace(1) on OpenBSD easy to use. I do not spend much time, plus I find testing my items on Linux, OpenBSD and NetBSD tends to find most issues without a lot of work and time.

This is not a "companies don't spend enough time with static and dynamic analysis of their software" problem, it's "less than a third of companies I worked or consulted for in the past 20 years mandated having input validation of any kind" problem.

Then you'll get hacked or have an outage, and unless you're a monopoly it will cost you. But will the people who made poor decisions be held accountable?

You can do a decent hardening job without too much effort, if follow some basic guidelines. You just have to be conscientious enough.

I was once told to stop wasting time submitting PRs adding null checks on data submitted via a public API. You know, the kind of checks that prevented said API from crashing if a part of payload was missing. I was told to stop again with my concerns dismissed when I pointed similar things out during code review. I left that company not long after, but it's still around with over a quarter of a billion in funding.

I would love to say that this was an exception during almost 20 years of my professional career, but it wasn't. It was certainly the worst, but also much closer to average experience than it should have been.

The time spend on hardening software is always zero or very close to that unless the company makes that hardening a selling point of the product they make.

In the world of VC powered growth race to bigger and bigger chunk of market seems to be the only thing that matters. You don't optimize your software, you throw money at the problem and get more VMs from your cloud provider. You don't work on fault tolerance, you add a retry on FE. You don't carefully plan and implement security, you create a bug bounty.

It sucks and I hate it.
