The type shown in the video is pretty common in Germany and besides its ability to make a room pitch black it also provides a decent protection against burglary.
Many, if not most of these shutters are certified for resistance class RC2 according to DIN EN 1627.

The title of the video is wrong, by the way.
It is not Rouladen, which would be a dish of filled rolled meat, but Rollladen. Rollladen is literally rolling shutter and it is really written with three l in a row.

I worked on a project a few years ago to build a system that used eye-tracking for context-sensitive voice commands. Imagine being able to say "zoom in" and have the computer zoom in at the place you're looking. Unfortunately the eye-tracking was never accurate enough for it to provide a good experience.

it always irks me when i read a sentence like that.

* if something went wrong, your site would've been down. completely. irrelevent and easy to recover from as a small hobby page, but incredibly expensive if you need to honor a high uptime SLA.

* stateless services that don't need schema migrations are still very easy to upgrade without kubernetes -- or load balancers for that matter.
I've been driving manual transmission vehicles for around 25 years at this point. It's gotten to the point that when I drive a vehicle with an automatic transmission, I'll actually use the parking brake to hold it in place when stopped at a traffic light (while the car is in neutral). Before I start, I'll put the car into drive, release the parking brake and then press the accelerator to start moving. With a foot operated parking brake, it's sort of like using a clutch when starting :)
>>> By using many accounts, you create clear isolation boundaries that require opt-in sharing.

In theory yes. In practice, you will achieve the opposite of that.

Developers and ops will have to juggle between 10 keys and accounts to get anything. The keys will end up saved and written all over the systems. It will be impossible to have audit between all the accounts and access.

I have been running a Pathfinder (table top rpg) campaign for the last several years. A lot of these rules are great hints for a dungeon master as well as for a writer.

However, I think these rules can easily be "how to write a shallow but emotionally compelling story" (surprise, surprise).

That said, having these rules on the table (so to speak) is useful for when you as story teller want to have something other than the obvious happen (ie, know the rules to break them). Try occasionally having extra, useless characters just to confuse people. Have detours and details that turn into their own story. Slow down or speed-up pace just for the heck of it. Let the players find ways to short-circuit all the apparent barriers and then have something different happen.
Fortunately, no one will ever say that's why I don't use emacs despite hearing its praises constantly. We live in a vim world (or vice versa). :)

Per-account isolation is great for security and especially reliability, if you run in to constant ratelimit issues like we do.
I don't feel like the article really addresses "highly regulated environments". To me, that means things like avionics, military equipment, medical devices, and nuclear power plants (cf. the list of things buried in most sufficiently-BigCo EULAs that you're not allowed to use the software for). Are there good examples of CD-like practices being used in these domains?

I'm also a bit disappointed at how generic a lot of the wording is. It seems like you could do a search-and-replace of "continuous delivery" with almost any other process improvement term (e.g. agile, kaizen, Six Sigma) and have people nodding right along for 90% of it. Is there a concise explanation somewhere that really makes clear how this is something more fundamental than devops-flavored kaizen? Or am I expected to read the entire "canon" before I understand it enough to evaluate it?

I disagree about the repetitive calculation being "entirely unnecessary".

Background: I (probably like many here) excelled at high school and undergraduate mathematics. I have a graduate degree in a heavily mathematics-focused branch of engineering (digital signal processing) and much of my work involves applying that math at a conceptual level.

I'm currently tutoring an adult I'm close to who is approximately at GP's starting level and has a strong anxiety reaction to math. I'm finding that the repetitive calculation aspect is important to being able to developing an intuition for the concepts.

The process that's working well for us so far involves alternating between practical word problems (to establish a motivation for learning the material), theoretical/background explanations (to hit the understanding at a high level) and repeated simple problems (to practice the mechanics).

I'm finding that, in terms of process, the repeated problem-solving is critical for two reasons. 1) It helps to build a sort of mental "muscle memory", and 2) it helps with developing intuition, since your mind eventually gets bored with the mechanics and starts to notice patterns.

Remember that mathematics at that level is all about building blocks. Every concept/problem-solving practice you learn is part of a tower of strategies; if earlier mechanisms aren't almost mindless, it's MUCH harder to build on top of that knowledge.
Yes, that's interesting recollection, now that I think of it the late 90s seems like a period of considerable experimentation with user input, e.g. the Microsoft Natural keyboards were somewhat popular, various trackball mice even for desktops, 2/3 button mice with various buttons on the side, trackwheels (lots more combinations that these days), wacom tablets, etc. I guess this stuff is still available, but much more niche now.

I wonder what happened? Maybe since computers are cheaper, more ubiquitous and people might use several (home, work, laptop), it's much less practical to use an exotic setup these days?

I can't answer for Segment, but our AWS account strategy is very similar, so we've found that there is still a need for a centralized KMS solution (system-to-system auth).

PrivateLink endpoints between accounts and VPCs if the service must remain private [1], public TLS endpoints either with or without TLS fingerprinting for services that must be public.

"You can create your own application in your VPC and configure it as an AWS PrivateLink-powered service (referred to as an endpoint service). Other AWS principals can create a connection from their VPC to your endpoint service using an interface VPC endpoint. You are the service provider, and the AWS principals that create connections to your service are service consumers."

Would people stop killing each other if the guns were taken away from them? Of course, not. However, gun control laws would make such an "endeavour" much more difficult and less likely to succeed as means is one of the key ingredients to any successful crime including a violent one. The guns create more problems than they solve, IMO. There are much easier ways to fend off a mugger or home intruder. In the vast majority of situations there's usually a better solution than using lethal force.
What was the “reason” given to change the process? Were these changes and steps addressing something (regressions, stability, quality...)?
Not saying your account is untrue, or that I can’t imagine management doing asinine things but it is still hard for me to imagine a) management willing to change something that’s not broken and b) developers that wouldn’t push back to said change.

Oh, sorry, absolutely. I'm actually talking about services that talk to each other using HTTP.
One option I've though of is using the public internet to connect them and use OAuth to make sure that they are actually allowed to communicate, solving the security issues on the application level.

Another option would be to allow only access from the internal network, but then you have to connect them somehow.
By your early 20s you should know if you need a teacher, or just a guide, or no one but yourself(plus textbooks&internet), for medium level difficulty and down. If you have to ask, I'm pretty sure you need a teacher.

For example, by the time I was in my last year of college, I regularly skipped 90% of class time, and showed up to take tests. I handed in assignments at instructor's office.

I don't process auditory information all that great, but I'm extremely efficient and robust in my processing of visual information including the written word, graphics, pictures, and video.

On some topics I have sought a mentor, with whom can provide a little guidance, and bounce ideas off of. But his is extremely far from the traditional instructor role.

So in conclusion, most people do far better in class. But for me it's slow, tedious, distracting, and out of sync with my normal learning processes. The few other people that I know who are like me, also skip the classes and have done well. You'll know because from birth, you'll be an excellent test taker, get bored silly in classroom environments, and have likely read 1000 books or more in just two or three years. We never asked "do I need a class", we just stopped going.

Having another interest to tie it to (especially if it's something you're more comfortable with) is huge. I have a CS degree, and for me, what bridged the gap into being comfy with "pure" mathematics (and appreciating it outside of any specific application), was my theory of computation class.

There's one thing wrong with that analysis. The US modernization program, with superfuze, has resulted in nuclear weapons which are about three times more lethal than they were 10-20 years ago.

It's the US which is playing the dangerous game, forcing Russia back into an arms race in order to ensure retaliation for a US first strike.

It varies a lot. Yes, secret societies tend to be more secretive. In some cases, though not Skull & Bones, membership is secret. And they generally don't have public parties as tends to be the case with fraternities. At least some members also generally live in fraternity houses while that's generally not the case with secret societies. That said, there are lots of variants of both as well as honor societies, eating clubs, etc.

We use ECR and have all of our images in our hub account, and make them readable from the prod/stage/dev accounts using a cross account policy.

For S3, it's more complicated because of object permissions and all the insanity that comes with cross-account writing etc.

Edit for more info: No explicit promotion process for containers. Engineers build images in our CI pipeline when their pull request is approved and merged to master, which is pushed to the hub account.

Nusret, a lucky overnight success?
As a godforsaken millennial in the big American city, I do see us spending more on experiences, food, memberships, digital content, locations — things that you can’t touch — than objects. This has implications for the overall productivity of society, maybe? We produce less stuff that goes unused in attics and garages. What we do produce, we’re more likely to consume immediately or scale trivially. So less work on stuff no one will ever use. Maybe. Theory.

It’s purely anecdotal, yes. I think research papers and brand acquisition patterns can substantiate the claims we spend more on fancy food.

It could be our tastes which have been informed by analog and minimalist culture movements which I first noticed in the mid-2000s.

It could also be because we don’t have much disposable income and since home ownership is so hard where the jobs are (big cities) those with money still have nowhere to put stuff.

tl;dr (and mathlessly) Colloquially, you'd hold something other than the photon stationary and consider the light's path in that stationary observer's frame, and then it doesn't matter whether proper time is rigorously defined.

For a handful of others in this thread:

While it's strictly true that proper time is hard to define usefully for a classical massless particle, you can still parameterize a null curve any way you want, depending on what it is you're trying to do.

In flat spacetime you're rarely trying to eke out a transformation much more complex than a Lorentz transform (the matrix for which involves \gamma, which is undefined for v=c), and so you're stuck with ds = 0. On the other hand, your objects on lightlike curves are probably light itself (classical or otherwise), so you'd generally look to something like an affine parameterization like k^b\Delta_{b}k^a=0 and k_{a}k^a=0 where k^a(x) are the components of the photon's momentum, or (aiming for E=pc) parameterize on the wave vector k (where v=c implies k^2={\omega}^2, where \omega is the wave angular frequency).

Other sensible choices of affine parameter are available, and typically give you freedom to pick out a momentum vector k^\mu = \dot A^\mu where A is the affine time; usually you'd do this so as to match the momentum-energy at the emitter or absorber (or the redshift along the null curve).

An experienced teacher, in a one-on-one situation, can identify the areas you're struggling with much more quickly than you can, and can guide you on a path out that you might not be able to see.

I've found that sole self-study can make it easy to convince yourself you're more comfortable with some set of material than you are, which can make it hard to see why you're struggling with the next conceptual layer up.
Elon Musk Just Revealed His Higher Motivation (It's a Lesson for All Leaders)
I think it's fair to say that those videos you linked are not examples of MVP / Lean, given how sophisticated the product was throughout the demo. The example that I've always heard (and couldn't find a link to now, so might not be true) was that, while Dropbox was in YC, they put up a landing page and a teaser video that only explained what the product would be once released, without even releasing it. That video generated a lot of buzz and signups, which was a lean way to validate the idea that people wanted the product.

Seeing as I can't find the video I imagine this story might've been embellished over the years, so if anyone was here for that I'd love to be corrected.
I have been really tempted by the ergodox ez, but really wish it supported pedal input as that would make a "pedal layer" super easy access.

I do believe he thinks he was being truthful and objective, however, fact is he was not unplugged. He is like the addict in denial already posited here to a point that it really makes me wonder about my own assessment of how 'little' I am online.
Another crazy thought is how this really feeds into the 'fake news' meme. A Times journalist basically not relaying the truth about a thing he himself is in control of, and not another party. How can you expect objective reporting, if he cannot even be honest about himself or his own actions?
He should have wrote the 'I failed at it' story with some deep thoughts on why for him, and for all who seem to be attached to the wire.
Good side: he was outed by the CJR practicing good journalism.

My high school calculus and physics teachers synchronized their classes, so shortly after we learned something in calculus, we would use it in physics. Since then I’ve learned this is not as common as it should be!

Perhaps it works especially well in that case because calculus was literally invented to do the kind of physics you learn in high school, so it’s a very natural combination. Linear algebra (e.g.) is so general-purpose that the overlap with another course might not be so continuous.
I've thought of this for the shift keys, I find that certain key combinations that require shift are a lot more awkward for my hands to do and I wonder if year after year eventually that is going to give me arthritis or increase the chances of it. I think that with a pedal it might make +, -, {, }, (, ) etc much easier on the hands to complete since they account for the worst stretches my hands have to make.
This is great. I remember the initial hacker news post. I remember how I thought it was trivial and that in the best case Microsoft and google would eat them. Glad to see that I was wrong. From that perspective I’m trying to figure out why I thought that despite all evidence to the contrary. And how I can avoid that type of mistake going forward.
When you read the comment about short range and the environmental impact of the batteries, they’re often highly upvoted by people that dislike electric vehicles too.

One of the earliest memories I have of really enjoying math was a unit on modular arithmatic from my 6th grade math class. The teacher introduced the concept with a hands of a clock metaphor, gave us a whole bunch of drill problems, and told us to watch for patterns. We had an easel in the class room where he collected the insights students had gained. Discovering the relationship with remainders by ourselves was incredibly cool.
