# Hot qubits made in Sydney break one of the biggest constraints to practical quantum computers

The unit cell developed by Dzurak’s team comprises two qubits confined in a pair of quantum dots embedded in silicon. The result, scaled up, can be manufactured using existing silicon chip factories, and would operate without the need for multi-million-dollar cooling. It would also be easier to integrate with conventional silicon chips, which will be needed to control the quantum processor.
The Subtle Dangers of the Comma Operator (C++)
If you’re going to have this argument, it’s important that you do it right.

The question is not precisely “how wide can I display code”. The question is “how wide is a side by side diff?” That is the worst case scenario for code reading, and it is the one where the worst classes of errors can slip in (one where neither author actually wrote the bug).

Linus answers this indirectly: you can easily diff 100 characters on a monitor smaller than his. What he says instead sounds like an invitation to suggest 200 column source code, which most definitely is a problem to diff.
Console is suppose to just be a web UI to quickly make a change or explore the feature. Any high quality engineering team should avoid make changes through console because it's not testable and repeatable.
For code change, use codedeploy or container through ECS. For configuration and infrastructure changes, CloudFormation should be the right tool.
Came here to say this. Wood is an incredibly dirty fuel. It makes coal look as clean as driven snow, by comparison.
This was the fifth static fire of the same rocket and frankly it wasn't seen as high risk at the time. If it was, I am sure they would have postponed it, as they did for the planned short-hop.

Of course "high-risk" is a relative term. They had a 1.5 mile exclusion zone for the test and the handful of village residents a few miles away were warned to leave their houses to prevent injuries from broken glass, so there was obviously some risk.

This was really a just a potential PR problem for click-baity new organizations and casual observers not aware of all the different projects SpaceX is working on. No one from NASA going to say maybe we should scrub Saturday's launch because they know the two not related in any way.

Also, there are many Elon haters are out there. I had a few try to blame Wednesday's scrub on Musk or try to imply that it was a failure. (Of course the fan boys can be just as annoying.)
I just don't understand this argument. As a contractor, you are hired with the understanding that, if someone needs to be let go, it is you before the FTEs. In general, you're paid more as contractor than as an FTE, and that's one of the reasons.

There is nothing about that that implies you're not treated with dignity.
If everyone knows the price next week will be $10 instead of today's $3, why would the today's price be $3? Why would supermarket sell it for $3, if they expect the price next week to be $10? Why not set it to $10 outright?

Opportunist speculators who buy up all of supermarket's stock aren't going to be in it for a long term: it's super high risk. They want to buy it cheaper than it should be, and sell for it for what the price should actually be. Holding onto product for long is very risky.
OK, but the other side of the coin is this: Water shortages due to unavoidable circumstances happen from time to time. It's good for society to have stockpiles of water in those situations.

But here's the thing: storing that excess water isn't free. Water is already commoditized, which means it's low-margin. If you as a private business, stockpile water for an emergency but can't charge more, you're probably selling at a loss. Which means, it's not economically sustainable to stockpile -- which means, absent the government planning ahead, shortages are going to be pretty bad.

On the other hand, if you know that you can charge 4x for a bottle of water during an emergency, then you might decide to stockpile, knowing you can make your money back when an emergency happens.

So which is worse -- "price gouging" but having the water available, or not having the water available at all?

Or to put it a different way: Stockpiling for emergencies is not free, and it's of value to society. Doesn't it make sense to compensate the people who do it?

I wonder whether the following analogy is correct:

Walking - library

Riding a horse - framework
Ah foot guns. I miss them so.

But really, I've been struggling learning swift... I became the iOS developer with little to no experience.
Assuming charitably for a moment that you're posting in good faith: if you're wondering why you're being downvoted, it's likely because these laws, their effects, and exceedingly strong evidence of racist intent behind them are all easily verifiable matters of historical fact.

(See, for instance, Jim Crow laws, redlining policies, poll taxes, etc. as many other commenters have already pointed to.)
The latest from the President and COO of SpaceX is that there are 900 employees working at Boca Chica alone.
From the comments here, I guess we are so. I have a 1080p 14 inch laptop and with Consolas at 15px and it's pretty much exactly 2 panes of 80 chars in vscode.

I would increase the limit if I can fit more though and I don't mind accommodating others who prefer a higher limit.
> People are making "judgement calls" based on highly publicized, recent cases of police officers doing "unreasonable things".

Define recent? Uneven application of force from the police based off of race is a known issue, and has been one for quite some time. In the past decade or so we have been able to witness more of these incidents due to the ubiquity of smartphones, but look no further than policies like stop and frisk as examples that illustrate the unjust policing of minorities [1].

In business, we have a philosophy of building goodwill. We do things to establish trust with our users so that when we inevitably screw up, they will give us a pass. But it's important to remember that goodwill is a finite commodity. Screw up one too many times without making concessions, and you will no longer get the benefit of the doubt.

No one is debating that there are plenty of good officers in the US, the issue is with the bad ones, and the lack of repercussions/changes in policy to address them.

So they bought ventilators. Did hospitals run out of ventilators? No. Did they even get to use the ventilators they bought? No. What's the problem then?
It is equally ridiculous that conservative CEOs equivocate and wait to see which way the wind is blowing, for fear of being branded liberal or leftist. Twitter is making itself a real legal bellwether right now.
You have likely never been in a situation where you have to weigh the purchase of food against the prospect of eviction. I grew up that way, and labelling those circumstances "edge cases" is a tidy way of dehumanizing the situation that many millions of people find themselves in. I won't do the work for you: lookup how many people are on SNAP programs. These are not edge cases.

Think market forces can solve all economic problems? Fine. But don't let that blind you to the fact that they have not done it yet and large numbers of people live in poverty and misery at the bad end of the economic scale.
I have been mislead about Schroedinger's cat, but now I get the absurdity.
However, I also feel there might be a conceptual mistake in the experiment setup: there -is- a conscious observer present inside of the sealed box: the cat. Thus there is no super-position and therefore the cat will observe itself when it dies (or stays alive), matching later experiments' results.
Science: it works! But Schrodinger's attempt at absurd comedy seems to have failed.
Your story is heartbreaking. Thank you for sharing. I would love to learn more about your hometown and hope it has fared better since 2002.
AWS and other cloud provider provides far more reliable and simpler features/toolkings than k8s. For teams that's serious about building services on the cloud, having k8s to take over certain area of orchestration make sense, but the "operating system" K8s provides is just a tiny peace of the overall infrastructure.
I'm not sure that's a useful comparison. Without treatment, HIV takes an average of 8–10 years to kill a person, but it has a >90% fatality rate.

You are comparing a sprinter to a marathon runner. It's hard to do the comparison justice using just one statistic.
I googled some but I can't find good information on freshwater snails? Some of the results reference cone snails, but those seem to be marine. How do snails kill people?
Well, it supports glTF which is supported by Unity and Unreal too. Most 3D packages like Blender support it too IIRC.

They even have a blog article on why it's the future (like JPEG for images) and how many big companies have started supporting it.

>If you ask a current PhD student how hard things are and then wait 10 years and ask how hard their PhD was you will get totally different answers.

I'm not sure this is true. From my own experience studying math, I often heard people remark upon how hard it must be and how only a small subset of people would ever be able to understand the concepts in a graduate level math course. I don't agree with this at all.

In my opinion, the reality is that learning is incremental, and everything new builds upon something that you've previously learned (hopefully). This is particularly true with math. I don't think that I had to work any harder to learn linear algebra in undergrad than I did to learn differential calc in highschool. I think the delta in difficulty between geometry and algebra, pre-calc and calc 1, diff eq and real analysis, is basically the same. But that is only true if you have a solid understanding of whatever came before.

This is of course a minor nitpick with your last point, because I agree with your overall point that k-8 learning is important. I think it's important precisely because of the reasons I mentioned before: you need to have a strong foundation in 'last years' concepts if you are going to succeed in learning this years.
I'm going to guess this is one of those mostly-mythical enforcement tactics. You do it once to one pub, and then talk about it loudly in pub industry magazines because you don't have the resources to sit in every pub every day just to check a few pints of beer tax don't go unpaid.
sure, that's why I was limiting it to {library_name}, though arguably node could be that.
DynamoDB is the wrong technology for this. You can't prevent phantom reads. Transactional databases (precisely invented for this!) are the way to go. To quote DDIA:

'A service that allows users to spend money or points needs to check that a user doesn’t spend more than they have. You might implement this by inserting a ten‐ tative spending item into a user’s account, listing all the items in the account, and checking that the sum is positive [44]. With write skew, it could happen that two spending items are inserted concurrently that together cause the balance to go negative, but that neither transaction notices the other.'
The approach I've been taking is using the source data to determine what index needs to change, and using the dom to swap out just that element. Here's an example:

https://github.com/remfs/remfs-delver-js/blob/master/compone...

Don't look to closely at the code as a whole. It's prototype quality.
The context was rather different (home setup), but all that you mention can be used as arguments Noth for and against redo, basing on situation in company, future needs, etc.

I have actually done a "lift and shift" where we moved code that had no support or directly antagonistic one to k8s because various problems reached situation where CEO said "replace the old vendor completely" - we ended up using k8s to wrestle with the amount of code to redeploy.
But even a tiny mortality rate is catastrophic when talking about city and country sized populations. The lockdowns happened for a reason, because this disease overwhelms public health.
Customer service work is unquestionably boring. The burnout rates for that kind of work is pretty high.
have you noticed that literally every other country on earth does way worse?

According to a website called “US news”. The US definitely has a few colleges in the top 20 say but so do a few other countries.
Texas is a great launch site because it has all the required points, south, starting eastwards over the gulf, corrupt government, no taxes. plus if you look at their the beaches it's clear that they destroyed all of them for oil/chemical/nuclear money over the decades already. Even if it has a wildlife protected area sticker attached to it, this means nothing in Texas.

You're not explaining the other side of the story.

Many felons are convicted and owe fees to their victims, or to the govt. If you commit a violent crime, or a financial crime, there can be a financial penalty. Many of the felons that want to vote, never paid back their victims, or the state, for the crimes they were committed.

The Florida proposition "restored the voting rights of Floridians with felony convictions after they complete all terms of their sentence including parole or probation"

Now, they want to vote, but still haven't compensated their victims, which was a part of the sentence, based on a lawful conviction.
"class trip to Africa"- Its strange they didn't require him to get a shot before going to a country in Africa that is a Malaria risk. I know a lot UCLA and Michigan students who did exchange programs to African countries and got shots before leaving.
Animation shop in the city center seems like a silly idea, especially if costs have to be tightly controlled to keep the business viable...
I recall deciding quite a long time ago that I was going to do 100 columns and not ask anyone. It was with great amusement that I noticed, not very long after, that JetBrains added/moved the default gutter warning to either 100 or 120 columns.

That said, I do 4 space indents and 100 columns, not either/or. 2 space and 100 is an invitation to excessive nesting over decomposition. If you insist on 2 spaces then I’m afraid I’m going to insist on 80 columns (and that you finally get off your ass and learn how to code).
Good idea but I wanted to call it "Web Vérité". Is that too pretentious?

Entities have state (including position) and ways of interacting with each other. This leads to new state in the next moment, which leads to new state in the moment after, and so on. Thus the more global state affects the future state. There’s nothing mysterious about any of this.

Usually when people make a deal about emergence they’re confusing the map for the territory. They couldn’t predict the overall state evolution just by considering the parts.

They’re thinking of their notion of the generic entity type. But all that’s out there in the territory are the entity instances with their specific state.

The parts can’t exist in a stateless fashion. It’s just that in our heads — the map — we can consider them in that fashion.

I would say the biggest JavaScript inflicted pain when working with React is the lack of a notion of value equality in the default mutable collections.

Coming from a ClojureScript background, it pains me to have to deal with all the idioms in React that hack around this fundamental impedance mismatch by forcing users to carefully maintain reference equality for collections between renders for perf optimizations, and more recently for correctness in hooks like useEffect.
I wonder what HIV would have done if it hit before mass adoption of protective equipment for sex. I think it could have brought civilization to it's knees.
there will still be the same number of 18 year olds who want to go to college as usual

That’s by no means certain at all. It’s plausible that many will realise that the degree isn’t as valuable as it once was and pursue a trade instead.
Sikkim Momos – Indian food series
What is the original text?
This reminded me of the hard science fiction novel Dragon's Egg by Robert L. Forward.[1] Its core idea is that complex, intelligent life could be possible on the surface of a neutron star.

He went to a lot of effort to try to come up with a plausible description of what "life" would be like in such an environment. That fired my imagination also, and I wondered how we could do such a thing in a scientific manner. Given the rules of the Standard Model, in principle almost all aspects of the surface conditions could be elucidated, but I feel we would be missing almost all of the essence of it. Just like a deep understanding of Quantum Electrodynamics won't help you determine from first-principles that Earth has pretty sunsets or that your hair stands up if you take a wool jumper off.

For example, the surface of a neutron star would be very bright in gamma rays, but those are subject to pair-production in the strong magnetic field of the star, making light effectively a short range sensory mechanism. Meanwhile, the enormous density of the crust means that it transmits sound incredibly well and at enormous speeds[2], making acoustics the equivalent of our photon-based vision sense! But it would hemispherical at short range and 2D in a complicated way at long range. Spacetime itself would be strongly polarized, atoms would be distorted into spindles and have strongly anisotropic behaviour, general relativistic effects could be felt in everyday scenarios, and there are likely dozens of other effects the we can't even fathom by merely staring at a handful of field equations that we developed in our comparatively cold, flat spacetime.

New York was pretty simple, the lockdown started late, when community spread had already started. At one point nearly 800 people a day were dying.

New York saw the curve decline start consistently in the beginning of May. Metrics are defined for reopening and that is in progress.

Armchair quarterbacks get the benefit of 20/20 hindsight, but at the time the scope wasn’t understood and officials were worried about the impact of shutting down school breakfast/lunch programs, etc.

Places like South Dakota and Wyoming are lucky, there’s less people in those states than in my upstate NY county, and they aren’t big travel hubs. No surprise there. With other places, you should hold judgement until time has passed, the data is pretty awful in places like Florida. With political factors involved, you won’t know impacts until you have good vital record data re deaths.

The liberty argument is bunk, protecting the general welfare of the people is a core tenet of US governance. We were headed to a recession already and may be heading to a depression, but the rationale behind the lockdowns was the preserve life, and it worked.
It’s a little hyperbolic, those are generally just datacenters. They’ve got lots of fiber running through them, sure, but most of the “blacked out windows” is being dramatized.

Structural reinforcements as mentioned for datacenters are also fairly normal, they’re often designed to survive the worst imaginable environmental conditions for the area they’re being built into.
If you modify breakat and a couple other options (foldindent, to make the autowrapped lines stand out from the others), you can make vim’s autowrapping a lot nicer for word-wrapping code.
These days I usually try to implement something from scratch before taking on a dependency. A lot of times I find I never need more than a tiny slice of the functionality a library would offer. And even if I decide I need one after all, I have a much better appreciation and understanding of what it's giving me. Over time I've developed a sense for what sorts of things are likely to be hard to do myself.
The blood bank “profits” from every donation. That’s what a donation is.

If you’re asking if they specifically test plasma for COVID-19 antibodies and scalp it to brokers, my guess is “probably not”. My blood bank has documentation about the disease tests they do, and they say nothing about testing for COVID-19 in particular.
Wonder why VC firms don't come up with some structure to allow short selling?

If they believe a company will do well, yet someone else believes otherwise, there is money to be earned by whoever is right.
> The SRE teams which used Rightscale at my last job used to have "buttons to press for things", which roughly translated to "If the primary node fails, first promote the secondary, then get a new EC2 box, format it, install software, setup certificates, assign an elastic IP, configure it to be exactly like the previous secondary, then tie together replication and notify the consistent hashing."

If I understand this correctly, all of the things could have been automated in AWS fairly easily .

"If the primary node fails" Health check from EC2 or ELB.

"get a new EC2 box" ASG will replace host if it fails health check.

"format it" The AMI should do it.

"install software, setup certificates" Userdata, or Cloud-init.

"assign an elastic IP, configure it to be exactly like the previous secondary, then tie together replication and notify the consistent hashing" This could be orchestrated by some kind of SWF workflow if it takes a long time or just some lambda function if it's within a few mins.
Still the very same tank welding issues I assume.
You can do a lot with libraries. Removing a framework doesn’t mean removing all third party code, you know. The fallacy of the excluded middle gets us into more trouble than just about anything.
Yes, but I usually run my lambda function in multiple regions

This gives user low latency if the service is being used

If I've to launch DO server in 10 region, it will cost me $50 even if I am receiving a few request per day.
I'd define framework as something that dictates your file structure. I don't view React to be a framework; Rails definitely is.
I think of it as driven by thermodynamics - the state is "collapsed" when it's too informationally entangled with the rest of the universe. It's not really "collapse", just our good friend positive entropy.
I kind of disagree with that, a lot of companies will use terms like "react developer" or "react native developer" because they're looking for specific skill sets, only targeting those skills by explicitly naming their role after it. A lot of bigger companies also usually higher through recruiters, who usually are non-technical and will make up those names.

In reality, you'll most likely be a software engineer specialised in react development.

Yes! The thing about line width limit in terminal isn't about display resolution and size only. As a man who prefers big characters due to conditions I always vote for lower line width limit. It is starting to get really uncomfortable on lines longer than 100-120 chars.
