JohannesH··on Danish physicists claim to cast doubt on detection of gravitational waves
I find it odd that the responses from the LIGO team and supporters are so hostile, while it seems Jackson have a fairly constructive perspective:

Jackson says he hope that “our concerns will be taken constructively and lead both to improved methods for data analysis and to a better understanding of LIGO’s results and its exciting long-term potential.”

It seems to me that Jackson just wants to eliminate potential flaws in the result rather than overturn the result itself. Isn't that exactly what we expect from the scientific method?

I wonder if it is a media created image that the tone between the teams are so hostile instead of collaborative.

JohannesH··on IBM acquires Red Hat
Very interesting read. However, he changed it before the bank added their signarture. I imagine that if you change the contract after a signature is added by one party, and then add your own signarture, that would surely be fraud... right?
JohannesH··on IBM acquires Red Hat
I'm curious. Anyone care to outline the legal ramifications of this action? What would happen if IBM tried to stop his side-project?

1. Would IBM be able to enforce the original contract as it was outlined when they sent it to him? Would he be liable to fraud or other similar charges (for instance if he altered the contract after IBM representative added their signature)?

2. Or would the altered contract stand up in court?

Even that could potentially be a breaking change, like if the folder was expected to be there by some application.
JohannesH··on How to Get Things Done When You Don't Feel Like It
I often find that when I'm tired I'm much more effective and less prone to procrastinate. I've always wondered how to achieve this effect while not messing with my sleep.
JohannesH··on Introducing Cloudflare Registrar
Do cloudflare want to be registrar for other foreign TLDs in the future?

I would love to see them support TLDs such as .dk, .de, .it etc. That way both me and my clients could begin consolidating domain registration in one place, instead of using expensive and shitty domain registration management services. Harder ones, like Tonga (.to) or Greenland (.gl) would be nice to have as well, but I don't think it's feasible (or possible even) to integrate with all countries.

JohannesH··on Raytracing a Black Hole
It is and I hate that movie for it. In theory I should love it, but the disconnect between trying to be realistic and totally ignoring reality, killed it for me. I usually love sci-fi movies, realistic or not. But I mean, if you're going to put so much work into making a main element of the movie seem physically correct and realistic, why wouldn't you put at least a little effort into making the rest of the movie somewhat believable. The movie goes between metaphysical, realistic and action-movie physics every other scene.

Can you say a little more about the reason you chose KeyCDN over CloudFlare or the other providers. What features are you using?
JohannesH··on Using Prediction Markets to Track Information Flows: Evidence from Google [pdf]
You might be right about the self-fulfilling prophecy. But this effect might already be in effect, as people might already have a gut feeling, while nobody cares (or knows) about it.
JohannesH··on Tempe Police Release Video of Uber Accident
It is entirely too easy for companies to hire poor people and call them "safeguards" with no regulation. I'll put my money on that the "safeguards" are poorly paid, poorly trained, over worked, and that the Uber are disregarding the many studies showing how incapable people are at doing a job like this (i.e. never ending monotonous surveillance interrupted by intense split second decisions). Come on, Uber implemented this system and put people in harms way, and their "safeguards" are not working and they should know that and take responsibility for that.
JohannesH··on Tempe Police Release Video of Uber Accident
Thanks
JohannesH··on Tempe Police Release Video of Uber Accident
In my mind this accident is on Uber no matter how you interpret the video.

Scenario 1: Lets say the pedestrian was visible to the naked eye and sensors. The model and safety operator still didn't "see" her and act in time. Who to blame? Uber.

Scenario 2: The lighting and environment was in a condition where neither the model nor the safety operator could see the road more than 10 feet in front of the car, yet neither thought it to be irresponsible to go at full speed. Who to blame? Uber.

I believe that:

1. The sensors should have detected the pedestrian from far away even if the lighting was bad at the time. I mean that's sort of the point with autonomous vehicles, that they are better at perceiving their surroundings and can make better decisions on how to act quicker than any human could.

2. The safety operators are not engaged enough in their tasks to be effective. I think people underestimate how boring it must have a job where 99% of the time you should do absolutely nothing other than stare straight ahead and be ready for a situation like this. This problem is hard to solve. Maybe we should be training the model on closed tracks and only release on the real roads when it passes some sort of test where it is put through various scenarios. Like a driving instructor for AIs.

For those of you who think the pedestrian is to blame. I agree that the pedestrian might have made a bad decision by expecting the cars to brake, however these situations occur all the time. She didn't dart across the road or jump in front of the car suddenly. Yesterday I helped an elderly guy across 4 lanes of traffic which took about 1 minute. All you can do in that situation is to hope you are visible to the drivers and that they will stop before running you over.

JohannesH··on AWS Fargate – Run Containers Without Managing Infrastructure
Right now, we have 2 services and 1 scheduled job running on an ECS cluster running on 2 m3.medium spot instances. However we are utilizing less than 10% of the resouces available so moving to Fargate would be cheaper and much more convenient for us.

Unfortunately Fargate isn't available on the Ireland region yet.

I wonder when Fargate will be hit GA and be available in the Ireland region.
JohannesH··on Amazon EKS – Highly available and scalable Kubernetes service
Keep going... EKS is still in preview, so you probably shouldn't rely on it in production just yet. However you could check out kops (https://github.com/kubernetes/kops), which makes provisioning a k8s cluster on AWS extremely easy. Good luck! :)
JohannesH··on Wekan: An open-source Trello-like kanban
I really like kanbanflow as a product. For example they also have a pretty nice integrated pomodoro timer with interruption logging.

However the reason I moved back to Trello was the interface was a bit old-fashioned, and I found it hard to get my team on-board on kanbanflow wheras it was really easy to get them going on Trello.

JohannesH··on Ask HN: How do you set prices?
I tried something similar... Our CEO set the price of our email service too low (oops). But unlike you we faced the music and doubled the price only a year after. The backlash was much smaller than I anticipated. We marketed the price hike by adding some requested features and made the payment term half as long so the price seemed to be the same. This made it easier for our customers to swallow. Of course we lost customers, but not enough to make a difference (about 5%).
JohannesH··on Use of Ad-Blocking Software Rises by 30% Worldwide
The only problem is that we're now pushing ad networks into much more murky waters... And believe me, they'll do anything to make their monthly budget.

Ever heard of native advertising? Basicly just a catch-all name given to ads that look like content. You might think that advertisers are playing nice and that they stick a "sponsored" tag on ads that look like content (as the law requires most places), but in fact they "forget" quite often.

JohannesH··on Use of Ad-Blocking Software Rises by 30% Worldwide
I work at an ad network and I've tried to push morals and ethics for 7 years now.

The problem is that the entire field is driven by sales people with very few exceptions. The only objective is to make more money tomorrow, so they only think about how they can squeeze the market just a bit more... Like "Oh there's an empty spot on that page, put an ad there now!", or "Hey did you see those ads that cover the entire page? Advertisers love those... I want you to implement it on all sites asap!".

Ethics, morality, user experience, security and privacy concerns are simply not a part of the equation.

JohannesH··on Data Loss at GitLab
I think you might be confused. One of the nice things to happen to OSS was the availability of transistors and electricity. Both made it possible to make millions of logic calculations per second without knowing it. :)
JohannesH··on Data Loss at GitLab
Untested backup === No backup

People like to say they have backups or a "backup procedure", but in my experience almost none of them ever tested the backup... Not even once. 95% of the time "having a backup procedure" just means "we have a replica of some data sitting somewhere with no idea how/if we can restore it, or how long it takes".

JohannesH··on Stripe launches new European payment methods
I'm interested in the nordic countries especially norway and denmark where nets are the most used payment provider.

One business case is that I'm currently working for a company with a fairly large public email service. We have a lot of difficulty handling subscriptions on our current payment provider "epay" who like you is an abstraction on top of the card procider nets.

More european ones? Nets maybe?

JohannesH··on Be Kind
Also as a senior developer you carry some of the responsibility for the junior's ability to make that mistake. You probably set up and maintained the development environment where such an error could slip through into production.

So in case of a critical error/melt-down you should first of all blame yourself and think about why you set up a process and an environment that let this happen in the first place.

Think about what went wrong and how you can prevent it from happening again. When I started at my current place of work, they had a horrible manual deployment process that was the cause of 99% of all problems they experienced. Rarely critical problems, but still annoying and unprofessional. So we implemented automated build, test and deployment process that got rid of almost all of these problems.

Now, whenever something bad happens, we realize it is a problem with the process (not the individual) and correct/improve it as needed.

JohannesH··on Google Will Soon Shame All Websites That Are Unencrypted
It is really hard for DFP to not allow non-secure creatives as long as you can create 3rd-party creatives. They do try to detect non-secure assets though, so they won't run on secure pages. See: https://support.google.com/dfp_premium/answer/4515432?hl=en
