But languages are easy, there is the whole field of PL theory to draw from. If you're randomly throwing things together like Lerdorf was, there's a missed opportunity.

But what is the universally regarded theory that k8s contradicts? I don't think there is one.

Give me 10 years and hind-sight and I'll have your answer.

I don't think this is right. The reason I say that is because for the most part, teams new to k8s aren't building and managing their own clusters, they are using a managed solution. In that case, an application deployment only need be a few dozen lines of yaml. Most teams aren't really going to be building deep into k8s, and it shouldn't be hard to deploy your containers to some other managed solution.

JackRabbitSlim · 5 years ago

Fair point, but then plenty of people were using hosted solutions for their naive PHP apps too. Managed solutions don't prevent poor/improper configuration in either case.

The managed hosts and/or their tools probably helped negate damage/resolve issues quicker. However I think that the idea that "all you need is a couple of dozen lines of yaml and a managed provider" is exactly why it's headed down a similar path.

For a real world examples just look at every improperly configured S3 bucket leaking data. Every private key accidentally posted to github from a careless 'git add -a'. Every API that doesn't properly check auth. None of these are within the purview of a managed hosts responsibility.

I'm not even against K8 in any of this. Just making the observation that - like PHP - it is empowering entire groups of people to do things they otherwise wouldn't be able to do.

I get the feeling K8 is the modern PHP. Software that's easy to pick up and use without complete understanding and get something usable. Even if its not efficient and results in lots of technical debt.

And like PHP, it will be criticised with the power of hind sight but will continue to be used and power vast swaths of the internet.

And that's a bad thing, but I'm sure you'd agree the right solution isn't for the police to permit lots of crime in poor neighborhoods.

JackRabbitSlim · 5 years ago

So inversely, it is the right solution for police to permit lots of crime in well-off areas.

I can't help but wonder if there is a generational divide occurring in these censorship debates. Some contributors to the discussion seem to believe that everyone has a natural right to post a video and have it available to (if not see by) a global audience. As someone who grew up in the 1980s this is a strange point-of-view to me, but I can see how it might feel more natural to someone who came of age in the 2010s.

Youtube et al certainly encourage the free and public flow of traffic. Their business model depends on it. So their responsibility to the public would seem to obviously overshadow the perceived protections as a "private company".

>> TEMPEST [1] (or Van Eck Phreaking) is a technique to eavesdrop video monitors by receiving the electromagnetic signal emitted by the VGA/HDMI cable and connectors

IIRC, I think it originally used the analog signals generated by controlling the electron gun in a CRT.

JackRabbitSlim · 5 years ago

Yes, but no.

tl;dr The signal from a DVI cable can be detected but at much more reduced ranges. See also; RAGEMASTER (Snowden leak) a range extending implant for video cables.

JackRabbitSlim commented on Don’t require a user to be interested twice: lessons on reducing signup friction bbirnbaum.com/two-lessons... · Posted by u/bbirnbaum

It’s a good lesson but let’s not forget that completing the signup is not the goal in itself. If you look at post-signup user activity you will find many users stick around for a few minutes and then leave, never to return again.

If someone can’t be bothered to click a verification email, then removing that step is not going to magically turn them into an active user. More likely they will be one of the many people who leave after a few minutes.

I do a signup/onboarding optimization for startups, and here’s what I found from a recent project:

1) The verification email was NOT a significant bottleneck to signups. That is, most people clicked the link.

2) Removing the verification step did NOT have a meaningful impact on conversion rates.

If you don’t have a problem with user quality then sure, avoid the verification step. But if you have a good reason for the verification step then don’t sweat the drop-off rates.

And more importantly: Treat signups as a leading indicator of success, not the ultimate goal.

Edit: On second reading I see the author is talking about a verification step that requires an admin approval, which could take hours. Yeah, don’t do that.

JackRabbitSlim · 5 years ago

On the subject of email verification; Why not split the difference. Verify but give a 24 or 48 hours grace?

I noticed you said "meaningful" impact and not "no impact". If your optimizing this seems like the best of both worlds in the slight increase of conversion and the security of verified email?

I have the same kind of website. I once showed it to an employer and he almost laughed.

It's like the internet has been overtaken by an army of advertisers and wannabees photoshop artists.

I'm curious about UX, because sometimes it's aimed to make consumers feel good, and sometimes it's to be productive. I'm wondering if UX is backed by science/engineering.

Increasing user productivity and usability by any % doesn't directly translate to revenue. Steering users to premium features or ad click-throughs does directly translate to revenue.

Revenue driven design will win every time.

I know. Lets move it all that annoying complexity to yaml/json/XML config files!

Now look at this app I can write in 30 lines of code with this framework! Oh and 500 lines of yaml across 2 dozen files but look the "code" is so sleek and sexy.

Joking aside I think he could have at least mentioned the difference between required complexity and unneeded complexity. Ironically it seems to spawn from attempts to reduce the first type of required complexity in a lot of cases.
