> I can’t quite follow the line of reasoning here. Can you simplify or rephrase?

I was pretty clear, and so was the original study you linked from nature.com. If you can't follow the reasoning of something that simple, should anyone take your claims to be coming from someone who knows what they're talking about?

From the second meta-study you linked:

> We found significantly higher secondary attack rates from symptomatic index cases than asymptomatic or presymptomatic index cases, although less data were available on the latter. The lack of substantial transmission from observed asymptomatic index cases is notable. However, presymptomatic transmission does occur, with some studies reporting the timing of peak infectiousness at approximately the period of symptom onset.

They state very clearly that though their analysis showed a lower secondary attack rate from asymptomatic index cases (0.7-4.9%), they have limited data from which to draw that conclusion, and that presymptomatic transmission does occur. Which means, you can catch SARS-CoV-2 from someone who doesn't know that they're sick.

That's according to the study you linked, and it's far from the claim you made that asymptomatic spread is "actually highly unlikely".
At that level connections is everything. His title us basically a chief smooth talker that knows important people.

I have been looking at using MDM for my iPhone so I can install trusted root certs and require it to be on vpn when not using a specific list of WiFi networks.

It is a hassle and as far as I could see it requires resetting the device and I’m not sure I can restore my backup over it and retain both.

It seems almost impossible to find these videos or channels intentionally, you can only stumble upon them.
Take it with a grain of salt but one of the soldiers involved in the Nimitz incident says the videos released are of diminished quality compared to the originals.
Sure, yes. I was referring more to ‘general-purpose dynamic allocator’ (malloc or so). I agree custom memory management/reclamation techniques can be fine for RT; just semantics.
Sounds like prescriptivism to me.
Holy ship.
We started 3v3 on normal difficulty, as some of us had AoE experience, but quickly had to go down to 3v2 very easy until we learned to win relatively consistently (this took quite a bit of time).

Hi,

The issues you have found are all assigned to me, or I created them. My task is to create blog posts, some of which being a hackathon and challenge. The KPI are impressions, other metrics are hard to measure. As a Developer Evangelist, I often need to learn new technologies, or dive into unknown areas connecting the dots.

You can learn more about our focus areas in our handbook: https://about.gitlab.com/handbook/marketing/community-relati...

I'm focussing on the Ops side, with a backend development background in the past 15 years. I was once a maintainer of an OSS monitoring project called Icinga, a Nagios fork back then. I decided to take on a new journey with becoming a Developer Evangelist in March 2020 (you can learn more on my website https://dnsmichi.at/about/ in case you're interested).

That being said, I've found it interesting to learn about web apps and their deployment, and dive into new things. Never having found a use case for trying Heroku, March brought up one: There was a Twitter theme of "Everyone is building a better Heroku" - https://twitter.com/adamhjk/status/1369704730218299392?s=27

From there, I thought of learning Heroku while comparing it with the 5 minute production app. I underestimated the challenge of creating a web app with a persistent backend, and decided to stick with the simple battleships demo I had initially found.

This state of the blog post felt good enough for me, and I did not include the persistent backend just yet, but moved it into a separate blog post. This is feedback I got during the review.

Turns out that this decision was wrong, next to other negative raw sentiments I had added in the blog post.

You can try to convince that it is not my fault, and I will convince you - it is, and I am standing up for it. Public and transparent.

I know we all get better from making mistakes. The lesson I learned today helped me improve a talk I gave at a meetup in my evening, it added technical insights as well as helped with the story line. That's the tracking issue: https://gitlab.com/gitlab-com/marketing/corporate_marketing/...

We will continue to iterate, and have a retrospective on what we can improve from the lessons learned today. Thanks for your feedback.
How are you scaling the editorial work you do for these? I saw the internal threads for Fly, and the work you put in was significant, and you can see what looks like similar guidance in a lot of the good Launch posts. You have to be aware of how valuable that work is. Have you thought about building it out?

I put off reading the book for ages because I was convinced that knowing about locks and atomic data accesses, and intentionally keeping things simple would be enough to stay out of trouble.

The book certainly does cover how to coordinate between multiple threads, but it goes further by pointing out that the real secret to multithreaded programming is designing things so that coordination is kept to a minimum. For one thing, the coordination often has the side effect of purging your CPU caches! You definitely get a lot of cache misses. Even if you use atomic operations on primitive types.

I believe you can get a lot out of the book even if you already know Java’s or POSIX’s threading models.

That would take a huge amount of investment in R&D that hasn't been happening... and that R&D could take a long time to produce a cheaper, faster way of fab'ing chips. Given the amount of money involved to develop fabs this would be a government-level investment to the tune of tens of $Billions. I say government-level because there aren't a lot of companies capable of that level of investment. Google, Microsoft and Apple come to mind but are they willing to plow tens of $Billions into what would likely be a decade+ of R&D that might not pay off? Perhaps a consortium of of companies could do this but it's hard to get competitors to cooperate. ("Hey, we all need chips so maybe we should cooperate in developing some foundry fabs?")
That depends on the TLD. For the American TLDs (.com, .net, etc.) you're right, there's barely any uptake. Several other TLDs (.cz, .no, .nl, .se, for example) have over half of their registered domains using DNSSEC. That's much more than TLS before the Let's Encrypt move happened.

The problem is also with cloud providers. Amazon Route 53, has only announced support a few months ago [1] even though the standard has existed since before Route 53 came into existence.

Perhaps it's time for browsers to consider DNSSEC to determine the security of the website, similar to how TLS and CORS have been added to protect web resources. The uptake would improve quickly if people wouldn't be lazy or lackluster about their DNS security.

No, I'm reserving judgement. I hope Microsoft won't ruin Discord, not least because I use it fairly heavily and I don't want to have to switch (again).

At least do me the favor of reading the link; "two Israeli studies" is in the very first sentence, and the second study is published:

> A separate study by Israel’s Sheba Medical Center published on Friday in The Lancet medical journal found that among 7,214 hospital staff who received their first dose in January, there was an 85% reduction in symptomatic COVID-19 within 15 to 28 days with an overall reduction of infections, including asymptomatic cases detected by testing, of 75%.

The author wrote a blog post about a project GitLab is working on to shine more light on the work that is being done. While the tone and content of the post needed to be better, as we have acknowledged in both comments and changes to the post, we did receive feedback that can help us improve this project going forward.

We're also going to learn from this and improve how we write blog posts in the future, too.

To address your last point, I want to be clear that the author is a valued member of my team. His hard work has been recognized repeatedly in recent weeks in the form of awards and other recognition. This blog post will not change the high regard I, and his other colleagues, hold him in.

Everything you have seen today is our team living up to its values: the author's bias for action in publishing this post, the transparency and being quick to say sorry in how we responded and addressed this community's feedback, and how our team assumed positive intent and worked together to try to improve and learn from this situation.

mind you DNSSEC is also far more complex then TLS. A misconfigration of DNSSEC can result in your entire domain not being responsive and thus have the risks in regards to implementation are far higher.

I don't really think this should be a reason to NOT implement DNSSEC, but it is still a reason many companies and organisations see it as risky.

If https fails it will go back to http. There's no security advantage here. HSTS is still needed.
> initial connections to http-only sites will be a bit slower (vs. the opposite which used to be true: initial connections to https-only sites were slower).

More than a bit. For HTTPS-only sites, the site could serve a stub HTTP endpoint on port 80 that redirects to HTTPS. The redirect causes maybe some milliseconds to a few seconds (worst case) of latency.

HTTP-only on the other hand can't do a HTTPS stub as easily (as the primary reason you'd want HTTP-only is probably that you don't want/can't deal with the certificate management - if you can set up a redirect from HTTPS to HTTP, you might as well go full HTTPS)

So the only option for HTTP-only is to not open port 443 at all - meaning Chrome has to wait out the 30 seconds (!) network timeout until it can try the fallback. So pure-HTTP sites would become a lot more unpleasant to use.

(A site might be able to cut this short by actively refusing the TCP handshake and sending an RST packet - or by opening and immediately closing the connection. I don't know how Chrome would react to this. In any case, that's likely not what HTTP-only sites in the wild are doing, so they'll need to update their software - at which point, they might just as well spend the effort to switch to HTTPS)
without a provider you cannot run many instances of the same store in the same App. (that's how I can run 3 times the same App in my demo https://taverne.uralys.com/demo)

zustand inspired me a lot to create the custom hooks for La Taverne, and you can also create your {store, dispatch} to use anywhere without React (and providers)
You built it so you can refactor it when React `${v+1}` comes out, or when Webpack `${v+.1}` breaks your build.

Working as a contractor is not that different. Just find someone to handle your taxes (although I understand that this in itself could be a headache for someone who only has worked as an employee). Also, as a contractor, vacation days are different as well: no work, no pay (whereas as an employee all your vacation days are always paid).
> Life connects back to time zero because everything prior was an important boundary condition, e.g. heavy metals made through exploding stars supporting elemental composition of life, etc.

The initial conditions were so uniform that it doesn't take the same level of detail to understand what happened, and we can look all the way back to the CMBR. A particle-by-particle reconstruction of interactions since the big bang won't make much of a difference in our understanding of what happened on Earth. Virtually all of the interactions arrived in our solar system in a very noisy fashion during star formation and it was up to the resulting sun to pump negentropy into the rocks and other matter.
There are bots that will check to see what zones are pointing to route53 and will then check to see if those zones are registered in route53. If not, they will register them and your domain is hijacked. Set up your domain in route53 before moving it, if you haven't. If AWS won't let you register the domain because someone beat you to it, point the root servers back to your old name servers and open a case with Amazon.
Nice, I hadn't heard of them, but does look interesting, I'll add it to the list to check out at some point.

Going through the docs just a bit, I see some things have you using docker manually, like "Deploy Persistent Redis with Docker" -- that's not necessarily a barrier, but it is already less simple/abstracted than heroku. But still might be worth it.

It sounds like a dumb tautology but parallel programming is easy for parallel problems. It is harder to say maintain several interlinked grid cells in a simulation in parallel than it is to partion a non-interacting set to N cores to run in parallel and let the main thread know when everything is done.
Good question. In a regular transistor, the gate does have capacitance but this is generally viewed as an inconvenient side-effect. For a capacitor, you make the gate much bigger so you get more capacitance. The other difference is that in a transistor you're connecting to both sides so you get a switch but the capacitor just connects to one side (handwaving a bit) so there's no switch action.
The JVM has its own garbage collector. Every language uses it.

There may be tiny differences in the way code generators and optimizers work, which mean they may not get exactly the same properties out of equivalent code. For example, if they're generating a lot of objects behind the scenes, the GC improvements might help more, or less, or even do worse.

But that's the kind of thing that's really dependent on the algorithm you've implemented. So mostly likely you get some benefit for free. If you don't, you'll need to benchmark to find out. The optimizers do a lot of work for you (and the JVM does a ton of language-independent optimization), but some things are up to experiment.

I don't understand how the "everything is a file" could apply for everything in practice. For example, Linux has ioctl(), which in practice are like a side channel. Granted, Linux doesn't apply this API philosophy too thoroughly.

I guess the "everything is a file" might have multiple meanings. For example:

(1) Everything is represented by a (file) descriptor

(2) Same as (1) and the descriptor has a file-like API (think read(), seek(), write(), etc.)

(3) Everything is an "byte addressable blob of bytes"

Meaning (1) is OK. But it doesn't tell nothing about the API the (file) descriptor itself would use. It could be a fixed set (like meaning (2)), or be variable depending on something else (like the (file) descriptor type).

Meaning (2) looks like too restrictive and inefficient to me and is the one I really have trouble accepting as a general OS primitive.

Meaning (3) surely can't be used for everything in practice, right? It's just to generic like "every computer architecture can be emulated by a universal turing machine." And it also seems too inefficient. But it could be very useful if the blob of bytes had an API like (2) or any other, including having an API depending of the "file type".

Is option (3) that folks are meaning when talking about "everything is/should be a file"?

EDIT: formatted the meaning list correctly.
