waschl··on Show HN: My from-scratch OS kernel that runs DOOM
Welcome to the club! Did almost the same and really enjoyed the serenity of doing something which never will end up in a product

waschl··on Show HN: Bullshit Remover
This should be an outlook add-in (ideally with a way to connect to an company-internal llm-api)

waschl··on Deterministic Replay of QEMU Emulation
Tried to apply it for debugging on my own OS, but couldn’t get it finally running after several days of trial and error…

waschl··on Did you lose your AirPods?
I guess broadcasting beacons via Bluetooth to nearby iPhones, same principle like AirTags work
waschl··on Show HN: SpecOS – A 64 bit OS kernel from scratch
Nice! Will follow. Doing similar things here: https://github.com/jbreu/jos
waschl··on Konrad Zuse (1994)
In particular this (German) presentation: https://www.analogmuseum.org/library/hamburg_hoelzer.pdf
waschl··on Tell HN: Spotify now inserts Ads to premium users as well
Maybe it’s a location thing? Until very recently I used the free version of Spotify and never experienced any ads in podcasts (which surprised me considering the amount of ads when listening to music). Since I have premium I didn’t listen to podcasts a lot, so I can’t tell if it behaves differently
waschl··on Ask HN: How do you handle tech use with your kids?
Our oldest got my old iPhone when she qualified for gymnasium at the age of 9.5. I have configured a quite strict regime via the iOS child control features (max 30 mins per day, no purchases, blocked tiktok.com). So far it works quite well, it’s enough to keep her connected to her mates, but restricted such that often she isn’t even using it even if she could. Whenever she can get screentime on another device she is will never stop until external force is applied.
waschl··on Ask HN: Share your favorite YouTube channels focused on mastering a skill/craft
Plasmo is great, his videos are so relaxing to watch
waschl··on How messed up was Germany's energy policy?
For sure growth at renewables is great. However the overall percentages you gave are all-year averages. It goes down to single digit % on dark windstill winter days.

Considering this and the fact that nuclear energy (Fukushima), coal (climate change) and now gas (Putin) are effectively „banned“, it’s really quite a mess.

waschl··on Amazon rainforest is losing its ability to recover from destruction
First thought: this is about some kind of Amazon product called rainforest
waschl··on $1 Microcontrollers (2017)
Yeah Adafruit is a good source! However one supplier of potentially many
waschl··on $1 Microcontrollers (2017)
Thanks,will try!
waschl··on $1 Microcontrollers (2017)
Semi-related: Since few months I am digging into tinkering and electronics. It’s really great to learn about modern era solutions which enable cool projects with low entry barrier.

However, I happen to learn about new solutions (new sensors, actors, boards, ICs) more randomly than systematically. I tried to google for databases, blogs or news outlets, but couldn’t find anything suited for my consumerish needs. Going through hundreds of pages for similar products on online shops also didn’t yield any good output. Do you guys know any such source? How do you keep yourself updated on interesting new products on the market?

waschl··on Ask HN: How does my Instagram keep getting compromised?
This! Have seen this personally in multiple friend’s mail accounts. This way it is “surviving” password changes, 2FA changes etc
waschl··on Microsoft Teams: 1 feature, 4 vulnerabilities
Ah and I thought it was my fault that lists stopped working all of a sudden.
waschl··on Black Friday/Cyber Monday Live Map
I guess it’s rather a clear illustration of shopify‘s international reach
waschl··on The Burnout Society
The book is called „Müdigkeitsgesellschaft“
waschl··on Porn Spam on Google Maps
Once I discovered a (for me) new feature in the iOS Google Maps app, showing recently uploaded videos and images for places in my vicinity. I was randomly browsing through it until I found a video of a woman on a car‘s passenger seat trying to pee out of the side window. Wasn’t expecting her to succeed…

Anyhow, reported it and went on, but couldn’t find it later when I wanted to show to friends.

waschl··on Apple pays out millions to student after repair techs shared her personal images
I wonder if smartphone vendors couldn’t provide a test mode which doesn’t require the unlock code for the phone. E.g. if I get my phone display replaced nobody needs access to my full personal data to test of the basics are working.

There could be a special mode accessible which allows testing of standard use cases.

waschl··on Jaguar Land Rover to suspend output due to chip shortage
What I couldnt find out so far is what the chip manufacturers are producing instead of automotive chips then? There must be another industry which has a significantly increased need or will get a lot of chips earlier than planned. Wondering which industry that will be.

Cant be the GPU market either ;-)

waschl··on Ask HN: How do we know Signal or Telegram don't store our data on their servers?
Telegram is storing your message content in their cloud for „cloud chats“ (default), as those are not end-to-end encrypted.

Telegram‘s „secret chats“ and signal chats are end-to-end encrypted. The servers still may store metadata, and there is no way to tell if they do than either joining them or let a trusted third party verify that.

To check if e2e encrypted message content cannot be encrypted via backdoors on their servers, you need to ensure they use proven encryption schemes and the client encryption does correspond to those algorithms.

waschl··on Does scrum ruin great engineers or are you doing it wrong?
I would agree that Scrum makes bad dynamics more transparent, yes. I would not agree that it generally makes bad dynamics significantly worse. This may happen and it’s certainly often claimed, but that is not what I can confirm from my experience.
waschl··on Does scrum ruin great engineers or are you doing it wrong?
Let me try: I think it’s about reflection and continuous improvement and providing a framework to enforce those. Scrum-haters in our group are also notorious for an attitude of negativity and resignation in many matters, while Scrum-friends want to improve all the time and find ways to do so, beyond what is obvious.
waschl··on Does scrum ruin great engineers or are you doing it wrong?
One more thing: In answer to Scrum advocates claiming its about doing it right I would disagree and replace it with understanding what is really (really REALLY) the purpose and idea behind it. Don’t worship the cult and don’t fight it because it’s the perfect target of rants, but see the motivation behind it and acknowledge that there may be reasons why it makes sense how it is to some degree. This doesn’t only apply to Scrum but to any other interaction of humans.
waschl··on Does scrum ruin great engineers or are you doing it wrong?
I am in a big project which assembles 45 teams and all of them shall adopt Scrum (for various reasons). My observation is that all those teams which have a sustainable pace with regards to architecture, technology, quality, output, social behavior, etc have done so while adopting and embracing Scrum in a clean way since the beginning of their existence as a team. All teams severely struggling with their content of work, output and collaboration have also severe issues with regards to Scrum-adoption, and show anti-patterns similar to the Stackoverflow thread creator‘s. However I would say the root causes (which we discussed in maaaany meetings) are certainly neither caused by Scrum nor increased by it, but individual mindset, dysfunctional team dynamics, pressure, weird contracts, etc. and would be there under any other or no process framework.

I am no Scrum fanboy (I think), but this experience and also from former projects make me quite sure to not blame Scrum in the first place when I see struggling teams, but trying to understand the underlying problems and solve those.
