The attack involves relaying the signal next to the car. Essentially mimicking the key fob being close to the car.

For what I know you can not clone the key, nor can you record the signal and replay it whenever you want access. It's a one time thing to drive away to your nearest chop-shop/hideout.

Adding to this,

My late mid 2014 MBP has the kernal_task heavy write issue. I has written over 15TB the last 61 days. The new nvme disk I installed two months ago is already at 2% wear:

  Available Spare:                    100%

A quick Google directed me at:

  - Spotlight indexing packages folders (npm, pip etc). Add those to the "privacy" tab in the spotlight settings to skip indexing.
  - The battery and or logic board may be failing.
Re:Loon’s final flight on Friday January 22, 2021 @09:54AM (#25872098)
Let's hope so. Though the price might be a hurdle.

The price per base station is quite high right now. Estimates range from $500 - $2500 (based on teardown)[1].

Tesla mentioned using iron in the lower end electric vehicles [1]. Though I don't know if that is the safe composition you are mentioning.

Since the article is in Dutch, here's my summary:

The Amsterdam municipality is demanding a startup to stop developing an app that can be used to prevent parking fines.

The app uses a dash cam to detect and notify users of a "scanauto" near their vehicle. These municipality cars use an automated camera system to detect license plates and fine owners who are not paying the parking fees. There is a 5 minute grace period between scanning and the requirement for a person to start paying for parking.

A user may use the notification from the app to start paying the parking fee during this time preventing a fine.

Re:Building replacement proprietary battery packs on Thursday October 22, 2020 @10:39AM (#24858478)
How can you tell from the small image?

I clicked through and the ebay link mentions: "Built-in protection circuit PCM for prevent over charging or over discharging."

Re:A self-killing web site requested by a customer (2011) on Thursday May 07, 2020 @09:02AM (#23102468)
While not actively developing infrastructure myself, I've always like the concept presented in the Hystrix package: https://github.com/Netflix/Hystrix

Even though it seems it is no longer maintained, the circuit breakers, fail over modes and all that are well documented.

And I don't know why Hystrix hasn't been adopted by a wide audience yet. It seems like a necessity in the micro service landscape.

Re:Low-cost portable ventilator (2010) on Saturday March 14, 2020 @06:07AM (#22574293)
I was considering an ask HN on just this. Having an effort from makers and professionals to come up with designs for mechanical ventilators when things get dire.

Now I understand jerry rigging medical devices is not advisable. But a pandemic like this may get to the point where DIY solutions may offer the solution.

I heard from a general practitioner that mechanical ventilators also have fine pressure control. Which would make the whole system a lot more complex. So given that I figured the concept was to flawed. But the design by MIT doesn't have these fancy ventilator function either. So it seems a cheap, available, basic ventilator would still be valuable.

"should be"? I can see how it's more expensive now. But I think that as a collective having things repaired is preferred.

For most manufactures the incentives now is to minimize repairability. Increasing the repair cost.

Having some regulation in place to limit repairability prevention may tip the scale a bit towards repairing.

Scrape off rust, replace chips that have been shorted.

Does depend on chips being available and some knowledge on how to diagnose the damages (e.g.: board schematics).

Here's an example of new age Macbook pro's dying from little water ingress (design oversight). And a combination of knowledge and a simple chip can fix your nearly write off Macbook. https://www.youtube.com/watch?v=jahtu1_idVU

I come across one site every two weeks or so. Luckily on the Reddit forums people usually copy or quote the article.

It's a bit of a nuisance. But overall, I feel this GDPR is doing more good than harm.

Re:Soviet radar hidden in Chernobyl’s shadow [video] on Friday March 13, 2020 @09:56AM (#22567255)
I couldn't quite figure out from the video if it was an early launch detection system and/or a signal jammer. Cause the video mentions both.

A cursory glance at the Wikipedia article also didn't clear it up. Does anyone know?

Re:Show HN: Coronavirus Spread Animation/Map on Monday March 02, 2020 @06:10AM (#22463395)
I think each post has like a 3 minute window to get going otherwise it's going to end up in the great dusty internet library. I'm surprised you stumbled upon it now.

Just so I can get an understanding how people find stuff on Hackernews, how did you come across it?

Re:Show HN: Coronavirus Spread Animation/Map on Saturday February 29, 2020 @09:58AM (#22450853)
The goal of this app is to show Coronavirus spread over time. Through all the sensational headlines, I couldn't really see how the virus was developing over the globe. This should give a better feel for both the infection rate and affected areas.

A side goal is to create a responsible interactive virus map. For that I took some notes from the ArcGIS post the other day about responsible mapping. Mainly using a blue color scheme instead of red tints.

For a more detailed motivation as well as design considerations please see the blog post. Or feel free to ask of course.

I hope this is of use to some of you.

Re:Amsterdam’s canal houses have endured for 300 years on Thursday January 16, 2020 @11:09AM (#22065822)
The city of Amsterdam keeps track of the "sink rate" of fixed points on buildings.It's a good place to take a look if you ever plan on buying something in the city:

note, in Dutch, but the color coding should make it clear.

Re:The new Dropbox on Wednesday June 12, 2019 @09:11AM (#20164162)
Heads up, downloads 20MB and might take a long time to load (for some reason it took over a minute on my laptop)
Does anyone know a bit more about the pricing? All I can find online is Google learning infrastructure cost.
Re:Learn CSS Grid through interactive screencasts on Friday December 22, 2017 @03:08PM (#15990503)
Great tool and great tutorial! I have a sense that I have a good grasp of CSS grids now.

In my Firefox I did have an issue with the sound cutting out after a while. Chrome worked great.

And I think your voice sounded a bit robotic at times. I'm guessing the threshold on your mic is a bit to high.

Or from some segments I gathered that small sound fragments were being played in quick succession. If that is the case, I think fade in-out with some overlap would give a more natural sound. Though, do note that I almost never work with audio, so I may be far off here :).

Re:When Should You Start Worrying About Getting Paid? on Tuesday September 30, 2014 @05:11PM (#8391278)
Just today I had to send a reminder for payment for the first time. The rules/guidelines presented here would have been a real time saver.

But I'm missing some steps here. Rather than immediately urging payment start friendly and become more strict after multiple messages. From now on I plan to:

1) Remind friendly over phone (informal)

2) Send formal reminder some time after

3) Send payment reminder with listed consequences.

4) Send final warning

All the while logging each step in case things don't work out.

Re:Ansible Quick Start guide on Tuesday September 30, 2014 @08:26AM (#8387755)
Great for understand the value of using Ansible.

But something slightly unrelated, I noticed the -vvvv command line option. Is this the new way to indicate verbose levels? Using -v3 and such is out of fashion?

Re:GaaP – Google as a Proxy on Monday September 29, 2014 @10:18AM (#8382908)
Annoyingly enough I've been in a situation where a needed a proxy to get around the corporate firewall blocking (constructive) blog posts. But Google proxy services didn't work (tried translate). I presume URL was filtered based on words like blog. Is there a way to obfuscate the URL using these services that anyone knows of?
Re:Soft Robotics Toolkit on Thursday September 25, 2014 @05:23AM (#8366316)
What a great resource. Really wonder how to program these actuators to get your desired motion. Using kinematics is pretty much out of the window with these systems. Everything uses learning algorithms I presume.
Re:Why video games are so expensive to develop on Thursday September 25, 2014 @05:10AM (#8366284)
They deserve it, but I've heard some rumors that game programmers are pushed to their limits with deadlines and cuts.

I've got a feeling marketing is eating up most of the budget for all AAA titles. I can understand seeing how consumers seem to love the hype train. Does anybody have a clue on the actual size of marketing in big productions? I couldn't find any facts.

They don't really seem to be sterile, rather just highly unlikely to get offspring: http://en.wikipedia.org/wiki/Panama_disease#Banana_breeding_...

It seems that with each meiosis step the banana plants become less fertile.
