lhoff··on James Gosling: Java, JVM, Emacs, and Computing History [video]
I listend to the interview as a podcast. It could have gone on for another hour if you ask me. I really like the long form interviews. It allows the guest to not just make there point but to tell the story how they came to that conclusion. That way its easier, at least for me, to internalise that knowledge.

There is a podcast run by the german newspaper "Die Zeit" [1] where the concept is that the interview goes on until the guest thinks everything is said. The episodes usually last between 4 and 8 hours. The longest taking 9h 40 minutes.

There is one episode with Ian McEwan that is recoded in english if someone that doesn't speak german is interested. That one just takes 2h so its not really a good example.

lhoff··on Wikipedia is getting a new look
The literal translation for carbon fiber would be "Kohlefaser" and that is also used quite commonly.
lhoff··on Jitsi’s Emil Ivov on scaling up during a pandemic
I run a self hosted Jitsi instance for my student Club. We are using for meetings with up to 50 people in a weekly basis. Works pretty well. Everyone accept the speakers has to turn Video off at that scale. With Video it works reliable up to 15 people.

There are some tweaks regarding framerate and resolution but that only raises the limit slightly.

Videoconferencing

lhoff··on DuckDuckGo is growing fast
DDG has a direct bang for google maps

!maps

The have a searchable list for every bang they support. https://duckduckgo.com/bang

lhoff··on Bardcore
I really like the "THE REAL SLIM SHADY" Cover from Beedle the Bardcore. https://www.youtube.com/watch?v=3okjFDo2aSU

EDIT: "WITHOUT ME" ist also great https://www.youtube.com/watch?v=XiV7hwfLXGE

lhoff··on Using Microsoft Word with Git
Oh that is great. Didnt knew that. Thank you
lhoff··on Building resilient services at Prime Video with chaos engineering
That and additionally it has implications for the development team as well. Using "chaos engineering" shifts the mindset of the developers. As a developer you now expect things to fail. You know that the "we make it work first and make it resilient later" approach will bite you sooner then later so you think resilience from the first line of code.
lhoff··on Show HN: Hndex.org – a full-text search engine of articles submitted to HN
Very nice. Works as expected. I stumbled about two things that could be improved:

- Add a search Button for convenient mobile use or if a user copy pasts things into to the search field using the mouse

- Add a comment counter on the result page, Since you index every article a lot of them have none or very few comments.

Oh and just a warning, depending on the jurisdiction providing the cache could be problematic under copyright laws since its basically a copy of the article.

lhoff··on Satellite images of the Beirut explosion site – before and after
Probably the one were there is only water now.
lhoff··on Satellite images of the Beirut explosion site – before and after
I read somewhere that the way the harbour and the storage buildings where structured(probably not intentionally) directed a big part oft the blast downwards, hence the crater. Matches the Videos i've seen were the explosion was sharply going into the sky. Only the shockwave was horizontal.
lhoff··on Satellite images of the Beirut explosion site – before and after
Seeing Videos from the blast yesterday left me speechless. This picture showes the destruction even better.

Seeing pictures like the ones im that tweet gives me hope: https://twitter.com/Nadia_Hardman/status/1291044300923510784...

lhoff··on Sledding athletes are taking their lives
Sure that would work as well. But i imagine that to be much more expensive then adding some requirements to the sledge that increases drag or increases the sliding friction
lhoff··on Sledding athletes are taking their lives
True, but nevertheless it shows that it can be done.

Formula 1 and motor racing in general is a prime example for that as well. Formula 1 has a strict set of rules that makes sure the speed and cornering speeds aren't going through the roof because of deadly accidents in the past.

The same could be done for sledding. Reduce speed by limiting what is technically allowed and improve protection of the athletes. From reading the article i could imagine that a headrest with a dampening foam is added to the sledge and prevent the helmet from touching the ice. Or add role bars to the sledge that protects the athletes from injuries during a crash. Or a emergency brake that stops the sledge from sliding all the way to the end after a crash. There are many more things that i can imagine. If it all makes sense has to be evaluated. But first the political will to change something has to be there. And i think that's the difference between formula 1 and sledding. In one sport there was instant death of the athletes and in the other the athletes deteriorated over time.

lhoff··on Pine64 announce the Pinecil, TS100 compatible RISC-V soldering iron
As far as i understand it, its basically that. But you want the temperature to be controllable and oberservable. So the microcontroller is controlling the display, heating element and user input.
lhoff··on Hackers take over prominent Twitter accounts in simultaneous attack
I guess the previous post was seen as a argument against compromised API keys.
lhoff··on Ask HN: Most life changing things that you bought?
May i ask which one you use?
lhoff··on Apple announces it will switch to its own processors for future Macs
> Apple ported many Pro Apps to ARM , especially their Logic Pro, Photoshop and they were showcasing Maya on ARM. That is about as Pro as it gets for Mac. > That reads to me Apple isn't going to have Intel for some high end Pro machine.

That conclusion seems a bit too far fetched from my point of view. There are many users that use Logic on a MBP and with Photoshop it's even more common to use it on a Laptop.

Sooner or later a ARM MacPro is comming but if i'd had to guess i'd say that will take a while. There were 6 years between trashcan and the current cheese grater. So maybe 2025 then ;)

lhoff··on Jim Keller Resigns from Intel, Effective Immediately
This!

Also health reasons have the advantage that it is seen as somewhat rude to ask for details.

The other unspecific reason that is used similarly is "familiy issues"

While i can understand why someone would use this "excuse" i see it as a generally bad thing because it fosters that "health" and "familiy" issues are seen as excuses and not always taken seriously.

The fact that we are discussing that here kind of proofs this point.

lhoff··on Show HN: I made an app for large group video calls where people shuffle around
Really nice. Also thanks for open source this.

I'm in a student club and we have our own Jitsi instance so we will probably run it on our own infrastructure.

Do you have any plans for a "random" feature? If not would you be open for pull requests?

lhoff··on Bolsonaro fires health minister, calls to reopen economy
Yes, when you look at Italy or Spain the overall mortality is way higher than normal.

https://www.lavocedinewyork.com/en/news/2020/03/26/coronavir...

It's important to look at the numbers by region and not the total numbers. And if you consider the overall mortality you have to take in mind that other incidents where people usually die went down (e.g. traffic accidents. But all these countries have now strict lockdown measures in place.

I'm sure that the death toll im Brazil will skyrocket.

lhoff··on CO2meter: A Python interface to USB CO2 monitor devices
There is a link to a manual for the ZG01 CO2 Module at the bottom of the page. So i guess the lib is for that module. But i couldn't find a source to buy that.
lhoff··on CO2meter: A Python interface to USB CO2 monitor devices
Iam looking to build my own CO2 Meter for a while know. I even thought about making a little series as christmas presents. My struggle always was to pick the right module. Its so hard to pick one and really trust it when you don't have a reference.

So i thought maybe i give this sensor a shot but i can't find a reputable source for it. Does someone knows where to buy it or uses another module that works good?

lhoff··on Jitsi Architecture – legacy desktop application (2011)
There are also .deb Packages for Debian/Ubuntu based Linus distributions. Setup takes 10 minutes via package Manager.
lhoff··on Ryzen 4000 Review
The now released 4000 Series of mobile CPUs is not the successor to the 3000 Series for Desktop CPUs. The 4000 series mobile is using the same architecture as the 3000 series desktop.
lhoff··on Why Is Facebook Not in the Cloud Business?
I think that doesn't weight as much in people's opinion because the counterfeit problem only came uo in the last couple years. AWS hat already a good reputation by then.
lhoff··on Ask HN: Are there good self-hosted video conference tools?
There are .deb packages for Ubuntu and Debian available. I installed it on a freshly provisioned VM running Debian 10 in about 15 minutes. They even provide a shell script to obtain an let's encrypt SSL certificate.

lhoff··on Why are we so bad at software engineering?
A former Professor of mine published a paper on a very related topic. He interviewed 54 software developer at the International Conference on Software Engineering. I found it a very nice read.

lhoff··on [dead]
The book recommendations looked good. I put it on my readlist.

The blogposted about Waldenponding, i term i never heard before, was also a nice read. I subscribed to his "whyisthisinteresting" newsletter.

So for me there was a lot to see there.

lhoff··on Ask HN: What do you regret you didn't know when programming for iOS or Android?
Afaik Flutter is basically a Game Engine. Its not using the build in UI Toolkit instead rendering everything itself and just mimics the look of the native UI.

I'm not completely sure about it, i just now it from listening to some talks.
