How can an electric oven be just 12% efficient?

I suppose:

1. You often have to pre-heat the oven, so during that time, you are not cooking food

2. The oven is rarely full, so instead of heating food, you are heating the oven

3. The oven remains hot after the food is removed, but you could argue that's low-grade heat, unsuitable for cooking

If my electric oven is just 12% efficient, I'd like to know why (and how I can get one that is more efficient). I understand that microwave ovens are much more efficient (I guess because the heat is generated inside the food). But they're no good for browning food, or baking bread.

I'm still lost on this notion that an electric oven is just 12% efficient. If that's true, then I could patent a device that harvests energy from electric ovens, and make a mint.

What do you believe is the role of the opposition if not to oppose/raise awareness about contentious legislation?

By definition they represent the minority (or else they would be the government) so almost any action they take will be "quixotic".

To me the fundamental job of the opposition is to point out the failures of the government and paint alternative paths forward. The opposition can move the public sentiment and there are enough poll watchers in the government to respond to pressures.

This is true and I remember when they were big headlines. I guess since I'm not in browser development, I'm used to the idea of contacting a known good server from my code, but my known good server being accessible from anyone on the internet.

Both are important, it's just interesting to see it written only from the other point of view.
You're not alone. We sent our K and 1st grade children back to school this fall expecting them to get (possibly asymptomatic) COVID at some point during the year. We're actually counting our blessings that this hit while they're at an age when they are likely to get some natural immunity without serious health complications. My wife and I are vaccinated, so hopefully any household contagion would be / will be moderate.

This hasn't been true for over a decade. 24/7 ATMs can be found at any convenience store, which are plentiful.
What do you mean? I am doing exactly what is expected of me. I am allowed to cycle on sidewalks when it's an underpass, that's the law in my city, because many cyclists were killed. There are even signs on the entrance of every underpass where there is no protected bike lane indicating that bicycles should go on the sidewalks.

I haven't made any judgments of value, mind you. I'm just saying that this is the only way I have of averting this issue.

Not necessarily. E.g. analyzing data from natural events is still "signals processing", even though there is no intent behind an earth quake etc.
Vegetarian is hard to understand once looking from an ethical perspective. Why is the chicken flesh bad, but the eggs okay while producing those eggs also has chicken killed?

Same for dairy.

It seems vegetarians are okay with lifelong encagement, and eventual killing, as long as they dont have to eat it. Leather is "vegetarian", and so are wool and silk.
What's different? I think that's obvious. Smoking kills people. Vaccines save them from disease and death.

That looks all the world like a Micro-Fit 3.0 drawing, whose contacts are normally rated at 8.5A, but here they're claiming 9.2A each. Also, the largest Micro-Fit terminal is made for 18AWG, but the article mentions 16.

https://www.molex.com/molex/products/family/microfit_30?pare...

I suspect what's happening is Molex is making a new version of the terminal with higher clamping force or better plating, to keep the temperature rise down at higher current, and larger wire grips, to accommodate the thicker conductor. (This will also allow more heat flow away from the contact.)

However, the contact pitch is unchanged from 3.0mm, meaning the cavities in the housing can't grow any more, so the wire insulation thickness will be limited. That's not a big deal electrically since it's only 12 volts, but it's a consideration mechanically since the wires will be less protected against abrasion, pinching, and other damage.
It's rather staggering to think that global emissions might continue to rapidly climb for another 20+ years yet at a minimum, given the numbers as they are now.

Indeed, the tale of Mohamed’s unlikely career—described as “the most tantalizing and complex story in the history of al Qaeda’s war against America”—is so utterly unbelievable that a Hollywood scriptwriter would reject it for being too implausible.

GitHub would be the opposite of kiss in my opinion. External dependencies and pushing to remote servers are just pain points.

> git init --bare

On your remote server is all you need to spawn a repo to push to, usually hook examples already included.

The hook can then directly checkout to my live directory, run migrations and restart the server without weird remote automations after every (or specified) push.

Gitea is just a little extra (setup once, touch never thingy) for quick edits and checks (it's a wonderful lightweight piece of software too)
Cryptsy (and Coinbase) in 2013-14 were the wild west compared to today, I don't believe either had 2FA and if they did it was SMS-based. Neither had licenses, KYC, things like that.

You could also argue the opposite: there are many more would-be attackers now that crypto is so much more popular; and the adage "not your keys, not your coins" still holds true. Still, I don't think it's naive to place more trust in exchanges today compared to that era in crypto.

These people had $1M in crypto on Coinbase, if you had $1M in cash would a good financial advisor tell you to store it in an account that doesn't earn any interest? (I know there are many flaws in the cash-to-crypto comparison.)
Edit: I was totally off base.

Original: Sorry, are you arguing that the vaccine has killed more people than the virus? Because there's no way you have numbers that actually support that. Given that there are now far more vaccinated than infected in America, you'd need to find near on a million vaccine deaths.

Oxford defines “signal” as:

1. a gesture, action, or sound that is used to convey information or instructions, typically by prearrangement between the parties concerned.

2. an electrical impulse or radio wave transmitted or received.

The second definition doesn’t require intent.
My impulse is that you’re trading one thing where the long term side effects are not 100% known (mrna vaccine) for two things where the long term side effects are not 100% known (covid and the mrna vaccine), and that there’s substantially more reason to believe long covid is a thing than that there are long term side effects to the vaccine.

Bigger issue though is that there’s no way to know exactly how long natural immunity will be effective either, as we know it also can wane in regards to this coronavirus. Giving a child covid now may be pointless to the goal of giving stronger protection to a more problematic strain later, if the strain comes along after the natural immunity has faded.

Realistically though, given current stats, the only statically valid reason to get babies vaccinated is to help lower community spread. Whether that’s asking a baby to “take one for the team” or reasonable depends on how much of a risk you view the vaccine as to children given the current data. (My personal belief is that long covid is a marginally higher risk than vaccine side effects so there’s no reason not to also lower community spread, but there’s no reason to think the baby won’t be fine either way).

I think the key to getting a good answer here is the “beyond heroku” part. It is hard to make suggestions without knowing why a platform as a service no longer works.

There are so many different options available but they very for different needs.

Regardless, I would assume that you are going to have to pay more for a managed solution that managing everything yourself.

I know the founders at https://releasehub.com/ and it sounds like it might hit that sweet spot for “outgrowing heroku” but “don’t want to do full time devops”.

Subsidy, and scale. The meat business is huge.

Once plant-based alternatives have more than half the market the price will come down a lot, which will increase demand further.
I don't get how you could possibly come to the conclusion that that's what they are arguing.
Agreed. In fact, if you do more than 100 requests/minute for the same IP, you should get throttled. If you want out of it, you should pay.
All of the energy is converted to heat. Some energy from your rig is emitted as light; but that's your monitor, and your monitor has its own power supply (which means that 600W is an underestimate).
File system is local to the server, so you DEFINITELY want to run it with lower permissions I have a separate user that has no access to anything outside of its ~ directory.

But it is great - it has access to ~, it has a built in terminal ctrl/cmd+` so I can actually operate completely from my VSCode in full screen. I was trying to hack my ChromiumOS to only launch that application and I would have a dedicated programing laptop that does NOTHING ELSE, which I've always thought would be cool.
I think Japan's metropolitan zoning has some merits over the US/CA models. It just seems like here in the US we chose cars over street cars too soon and forced everyone to homogenize neighborhoods going forward. The idea of a mixed use zoning seems like a smart solution among other things we can try here in the US to clamp down on what I call "concrete hell."

Agree, it's always funny to see people using runtimes they are not used to using, so they don't know how to configure it properly, like assigning how much memory it can use. Wouldn't trust these results too much as a consequence.
> I’m using Apple Maps for the app that I’m developing now. The alternative would not have been Google Maps. It would have been MapBox.

It's easy to make a theoretical stance like this, but Apple Maps and Google Maps are free in an iOS app, but MapBox is not. If you were forced to switch off Apple Maps for some reason, it seems likely the free option would win out.

> it simply hardened my resolve to avoid third-party dependence, wherever possible

all of these libraries are third-party dependencies...

> Google Maps will give app developers like me severe sticker shock

If we're talking just about the javascript API, in my experience if you're using more than just a very local map, people always have very wishful thinking about MapBox pricing and it usually ends up almost the same as Google Maps pricing. This isn't an accident, they need to be a better priced alternative but they also need to pay the bills. The pull to switch at that point would be if you need better address lookup or something.

If you are doing a very local map (like the equivalent of a few tiles for your average user), you're often better off just rolling your own tile server. People are often surprised how easy it is.

Intel Unattended Update Restarting PCs/Servers Without Notice
I just don’t understand the whole natural immunity vs vaccine debate. If you want natural immunity the safest way to achieve that is be to have a breakthrough infection after being vaccinated.

My guess is that maybe people overestimate the risk of getting the vaccine? But that also seems to be crazy since COVID has killed over over half a million people in the US and over 1/3 of the US population has taken the vaccine and been fine - the most common bad reaction is being wiped out for a day.
The pattern probably wouldn’t be random then.
"To combat this"

Did you actually need to?

That's one of the things that always threw me with complaints about cold starts - how many apps/etc do I use daily where I interact, and there's a 10 second delay before something happens? The answer: quite a lot.

Yeah, we can do better. And in fact, with Serverless, -most users will experience better-. It's only when load is increasing that you see those delays, and then it's still only a delay. Not shed load.

The fact I can experience that delay easily in dev makes people think it's going to be a huge problem, but, A. In real use it probably isn't as common as it is in dev (since you have way more traffic) B. You can design to minimize it (different API endpoints can hit the same lambda and be routed to the right handler there, making it more likely to be hot), C. It forces you to test and plan for worst case from the beginning (rather than at the end where you've built something, and now have to load test it).

Not to say to use it all the time, of course; there are plenty of scenarios where the cost, the delay, etc, are non-starters. But there are also plenty of scenarios where an engineer's instinctual reaction would be "too slow", but in reality it's fine; your p95 is going to look great, and only your P99 is going to look bad (on that note, a slow API response accompanied with a spinner is a very different thing from a UX perspective than a slow page load with no indication of progress), and even then it's predictable when it happens, and it forces function scale out rather than tanking a service. Of course, it's often not obvious upfront which scenarios those would be until/unless you try it, and that's definitely a barrier.
The average person does not understand that hooking up a device to the internet is like moving into a unlit, unregulated, unpoliced neighborhood. Shady people could come knocking at your door with heavy weapons, and you had better have ample and up-to-date defenses already in place or they are coming in for a visit.
Maybe the source's rotation axis is responsible for this.
How is it not? Compare the number of people who got immunity through COVID infection / those who died of COVID vs. number of people who got immunity through vaccination / those who died of the vaccination.

I'd go as far as to say it's evil.
This article in the NYTimes was an excellent follow on to the Pandora Papers. The question is, will anyone actually do anything about it? I predict a temporary spasm of anger and shouting followed by the typical malaise. The only thing rich people are starting to be concerned about is average folk no longer willing to work according to the old rules, hence the current labor imbalance around the developed world.
> I feel this is a gross misrepresentation of AWS Lambdas.

AWS Lambda is a serverless compute service that lets you run code without provisioning or managing servers, creating workload-aware cluster scaling logic, maintaining event integrations, or managing runtimes. With Lambda, you can run code for virtually any type of application or backend service - all with zero administration. Just upload your code as a ZIP file or container image, and Lambda automatically and precisely allocates compute execution power and runs your code based on the incoming request or event, for any scale of traffic. You can set up your code to automatically trigger from over 200 AWS services and SaaS applications or call it directly from any web or mobile app. You can write Lambda functions in your favorite language (Node.js, Python, Go, Java, and more) and use both serverless and container tools, such as AWS SAM or Docker CLI, to build, test, and deploy your functions.

https://aws.amazon.com/lambda/

Edit:

> it's widely known that if your API handles more more traffic than a few requests per second then you're better off putting together your own service.

How is it widely known? Is it on their documentation clearly or in their marketing materials to use another AWS product?

That's what's I mean by over marketing here. Requiring insider baseball knowledge because using it as described footguns your company at infection points isn't a great customer experience.
You are right of course, but this whole phenomenon really rubs me the wrong way. There is a whole host of podcasts now that provide a large audience to borderline crackpots. I believe it actually pushes people who are maybe otherwise quite intelligent to adopt such theories, because of the large audience that can now be reached with such stuff. Another good example is Avi Loeb and the Alien-Omuamua theory, explained quite well here: https://www.reddit.com/r/slatestarcodex/comments/o1dhlf/comm...

>>>Reform or revolt, those are the choices, and revolt is guaranteed suicide.

Revolt has worked out decently for the Iraqi Kurds and the Taliban. Jury is still out on the Burmese and the Houthis. Libya is a violent mess but technically they successfully overthrew the central government with significant external help, so at the very least that's a non-fail. Just for a few timely and relevant 21st-century examples that disprove your statement of "guaranteed suicide".

I am in fact following a couple of the people you mentioned. The critique isn't that no good China watchers exist. It's that most of them are like Gordon Chang instead of Kevin Tellier.

I don't see the need for you to resort to confrontational hyperbolic strawmans. The fact that good China watchers are a small minority, is very bad for western understanding of China, and thus very bad for rational policy making that actually addresses issues rather than stirring up emotions or manufacturing consent for a war. This isn't just my own opinion; Kishore Mahbubani, ex-Singapore diplomat, ex-UN security council head, has spoken extensively about this problem.
Being the healthier alternative isn't the goal. The intent is to be the green alternative or the kind alternative. Thinking it's inherently healthier is something I hear more from detractors than supporters. I eat meat alternatives because I like meat but believe in climate science and like animals. I'm not pretending I'm on a diet.

Last time I tried this was a few years ago, but seems like its still the case.

For an initial burst of traffic, your functions' cumulative concurrency in a Region can reach an initial level of between 500 and 3000, which varies per Region. After the initial burst, your functions' concurrency can scale by an additional 500 instances each minute. This continues until there are enough instances to serve all requests, or until a concurrency limit is reached. When requests come in faster than your function can scale, or when your function is at maximum concurrency, additional requests fail with a throttling error (429 status code).
Usually these directories are owned by another group (www or www-data) so that your web server program (nginx, apache, etc) can access them without running as root. If you add your user to that group, you should be able to manage files in your web root without sudo. Be careful with permissions, though - you may need to chown to set the group after copying so that the files are readable by your web server.
