This is just incorrect information.

> By the end of the 1980s, all of the grammar schools in Wales and most of those in England had closed or converted to comprehensive schools. Selection also disappeared from state-funded schools in Scotland in the same period.

https://en.wikipedia.org/wiki/Grammar_school

There are private schools that call themselves grammar schools (paid schools, not state funded) and some grammar schools still exist in Northern Ireland.

But the system that defined what a grammar school is - has long since been abolished, and all free-access grammar schools were completely gone from my area before I was even born.

—-

EDIT: seems like the some state funded selective grammar schools exist but they are not exactly distributed evenly.

So, I am wrong; and this situation is actually significantly more class-enforcing than it used to be. Amazing.

Key word being "most". I attended a state funded grammar school in the 2000s.

I think that it is thought (https://en.wikipedia.org/wiki/Riffle_shuffle_permutation) that seven riffle shuffles randomize a deck. So you may be misremembering that eight returns it to the original state.

Shows that perfect shuffles can return the deck to the original state.

Vomit draft can be great tool, but there's additional risk in science to keep in mind...

I've heard of a person who advocated this kind of draft, and then did a vomit draft themselves for a research project, with the draft including discussing stand-in results of an experiment that they planned to do.

Their colleague on the project saw the draft, and called out that the experiment had not been done. The writer said that they'd only written the draft to see what the paper might look like, once the experiment was done.

But the person who wrote the vomit draft had a problem doing the experiment...

Then that person submitted the paper anyway, with the vomit draft stand-in experiment results, and the paper got accepted. And without telling the other people on the project.

I understand that the story got a lot worse from there.

The vomit draft wasn't the only problem, but if you see someone vomiting drafts that are effectively scientific fabrication as they stand, I advise being uncomfortable with that, and emphasizing to the writer that this is a more dangerous practice than it might seem.

I think the problem here is that they submitted a fabrication. If someone is prepared to do that, I don't think how they drafted the document is really the issue.

Don't know what Giphy has, but creating and sharing a gif from a movie would be fair use and not subject to copyright.

You're not going to watch a movie in gif format, and it would be a derivative anyway.

Fair use is not a global concept.
gjhr commented on Ask HN: Why aren't there other biographies of Steve Jobs?    · Posted by u/fdeage

Why does Jobs command such rabid adulation?

He was an asshole, so vain that he would get a new car every X number of months just so that he could be the guy without license plates, and so selfish he wouldn't give one of those dozens of cars to his daughter whom he refused to acknowledge.

So he made popular products, big deal.

What a disgusting human being he was.

I certainly don't adore him, but would probably read a good biography about him _because_ he is such a controversial figure.
gjhr commented on AWS Lambda Cold Start Times   filia-aleks.medium.com/aw... · Posted by u/valgaze

I think you are thinking of reserved concurrency - with reserved concurrency you can only run as many instances as you have reserved. With provisioned concurrency you can run as many as your quota allows but you are guaranteed to be able to handle as many concurrent instances have provisioned. Neither one of these are going to help you with cold start times, it is not defining the number of instances running, its just reserving a portion of quota so that they can run. Where provisioned/reserved concurrency comes in useful is keeping a run-away lambda function from starving out other functions either by guaranteeing a portion of the quota for the other functions or keeping a function from exceeding a number of concurrent executions.

The "ping" technique you mentioned is one way to keep a function warm but if lambda decides to start a second instance of the function because the hot one is handling a request, then that person is going to take a warm up hit and nothing you can do about that.

If you are really latency sensitive then lambda might not be the right choice for you. You can get a t4g.nano SPOT instance for about $3.50/month and you can keep that warm, but that is probably a whole lot more then you are paying for lambda.

Provisioned concurreny does decrease cold starts.

Reserved concurrency both guarantees a portion of your concurrency limit be allocated to a lambda as well as capping concurrency of that lambda to that portion. Reserved concurrency has no cost associated.

Provisioned concurrency keeps a certain number of execution environments warm for your use. Provisioned concurrency costs money.

Depends on the location. In the UK IIRC mortgage payments are typically lower than rent payments, assuming you can find the initial deposit.

Yup. In the UK the benefits of owning are clear, but the entrance requirements can be very high.

> When you run Terraform against AWS on the subnets part, it will create (anytime you deploy) the missing subnets

That is one of the core features of Terraform? Detecting and fixing drift is useful.

Hi, I work on the portal team. Would you mind sharing what the issue is you're seeing?

Hi, thanks for replying. I'll send you a message on Monday when I get back to work to recreate it.

I'm going to ignore the "Shit HN says" vibes on this one for the most part, but I suspect that Microsoft and the Azure team specifically might have some relevant thoughts about building distributed systems regardless of if you like their dashboards or not.

As for Blazor, I think you might be missing the larger point here that I am trying to make. But .NET is still this Windows thing in the minds of most people. That hasn't officially been true for a couple of years now but the .NET crowd are coming to things like Linux and Front End now for the first time.

There are about to be a lot more conversations between say the React crowd and the Enterprise app development crowd, I am actually excited to see what they can all learn from one another.

I'd agree with them that the portal is terrible. Multiple times a day I get blank page errors, where the page is completely blank except for a single non-sensical error message in black text.

However their actual services are also pretty terrible. Pretty much everything takes significantly longer to deploy than the AWS couterpart. There are so many preview and deprecated features that it is often hard to judge exactly what feature set you are getting, this is often compounded by the fact that almost everything has multiple SKUs which also change available features. Azure AD RBAC is a bit of a mess, although its conceptually simpler than AWS IAM policies its just a pain to use in practice, and its often slow for changes in permissions to actually reflect. Azure VM disks are annoying to use too, you can't set the size of the OS drive at creation and extra data disks come unformatted. "Grossly incompetent" is probably an overstep though, Azure is very impressive, just not as impressive as its competitors right now.

Having said all that their are a couple places where Azure really shines in my opinion:

* Resource groups (GCP has a similar feature) allow you to more easily keep track of related resources across services. * Price transparency. Many (not all) services tell you up front hourly/monthly costs as you are deploying them through the portal. You don't have to track down a pricing page or calculator yourself. * Azure functions are amazing when using C#/.Net. A huge amount of the regular boilerplate is abstracted away into simple C# annotations so you can get a large % of business logic.
