geijoenr··on In a high-stress work environment, prioritize relationships
I think this is almost spot on.

There is also people with just toxic personalities that everybody tries to avoid. In Europe unfortunately, is not easy to get rid of such characters and they often victimize teams and jeopardize entire projects.

Septic avoidance and minimizing interactions, sticking to process and keeping the distance are absolutely necessary for mental health.

geijoenr··on Ring of galaxies challenges thinking on cosmos
It looks to me like an alien smiley :) of course aliens have only one eye.
geijoenr··on Quantum computing's reality check
What is happening with QC is very sad.

Research on this topic should be a long term scientific endeavor, like nuclear fusion has been for many years.

Not the circus it has been so far.

geijoenr··on A bullying scandal closed a historic astronomy department
The fact the department had to be dismantled to solve the issue indicates the bad actors had effectively taken over.

This is clearly a failure of leadership that dragged for way too long.

Those kind of personalities need to be punished early and decisively otherwise everything rots.

geijoenr··on YouTube's crackdown on ad blockers intensifies
From my point of view YouTube with Adds is unbearable. And I don't feel the subscription service is offering as much value as any other streaming platform.

If it was a bit cheaper I would may be consider it, but for my specific use case (just watch random videos and some channels) at this price is just not worth it and I will just stop using the platform.

geijoenr··on MSX-DOS
Check the readme on this:

geijoenr··on MSX-DOS
MSX was a Japanese home computer standard indeed, developed in collaboration with Microsoft, who provided the BASIC ROM implementation. It became very popular in Japan and in a number of European and South American countries. I wasn’t aware that MSX-DOS was also started by Microsoft but I am not surprised. Later versions of the OS were developed by ASCII corporation in Japan.

Fun fact is that the source was released not long ago with restrictions, and there is a newer version developed by an enthusiast called Nextor. Still in use today by many hobbicists.

geijoenr··on DeviceScript – TypeScript for Tiny IoT Devices
The github project indicates "DeviceScript brings a professional TypeScript developer experience to low-resource microcontroller-based devices."

If you tell me is a toy, and somebody's pet project: fine. Is all about having fun.

But then don't mention "professional" in the project description.

geijoenr··on DeviceScript – TypeScript for Tiny IoT Devices
Is really hard for me to understand how running an VM on a resource constrained device has any benefit. There is a reason why those devices run using very lightweight "OS"s like FreeRTOS and Embedded C.

Why the constant obsession to apply a technology designed for a specific purpose everywhere else, even when it doesn't make sense?

geijoenr··on Accenture would cut 19,000 jobs
They are a body shop. Subcontracting any crap permanent employees won't want to do.

That's why they have so many employees, that's literally their "stock".

geijoenr··on Fuzix OS: Unix for the Z80 and 680x
I think indeed one of the starting points was UZI, it is mentioned somewhere in the readme or license files.
geijoenr··on NASA, DARPA will test nuclear engine for future Mars missions
The speed of light is the frame of reference. It remains constant for any observer no matter at which speed is moving.
geijoenr··on NASA, DARPA will test nuclear engine for future Mars missions
It depends on the mass of the ship, but yes; quite a bit.

https://www.quora.com/How-much-energy-does-it-take-to-accele...

I don't think that means is unfeasible if the energy source allows for that.

geijoenr··on NASA, DARPA will test nuclear engine for future Mars missions
Yeah well, we don't really know what happens at high speeds. Probably biochemistry stops working at 0.3c? It doesn't seem structural materials would remain solid at 0.95c... who knows.
geijoenr··on NASA, DARPA will test nuclear engine for future Mars missions
With a spacecraft big enough to live in, we are talking of a time frame not too different from the one from the age of exploration by sea. I have no doubt many people would want to take such a trip even if it takes 10 years to get back to earth.

Unmanned spacecrafts would be able to go much faster, sustaining more dramatic accelerations. So getting cargo and robots there for support would be way faster.

geijoenr··on NASA, DARPA will test nuclear engine for future Mars missions
Definitely a common sense step in the right direction. Humans going anywhere beyond the moon using chemical propulsion seems quite problematic due to all the unsolved issues related to radiation and micro-gravity.

Now talking speculative fiction, the real breakthrough will come if we figure out a way to induce acceleration without an action-reaction process. Just an energy source, and no propellant. Being able to sustain 1g for a few months on a heavy spacecraft means interstellar travel (proxima centaury) would be within grasp.

geijoenr··on Apple postpones AR glasses, plans cheaper mixed-reality headset
I guess this is bad news for the AR market. Apple delaying entry means technology is not mature enough for a quality consumer product that can go into the mainstream and indicate the category will remain niche for a few more years.
geijoenr··on Ancient Apocalypse reviewed
Seriously? It looks to me that guy is perfectly aware is talking bullshit. And disparaging archaeologists is part of the publicity game. He is just an entertainer trying to make money.

Why would any scientist have to descend into the mud to argue? Just let time run his course and wait for Graham to run our of ideas, people will forget about him.

geijoenr··on Archaeologists ask Netflix to reclassify Graham Hancock’s docuseries as fiction
The problem with Graham Hancock is that he pretends to be scientific while disparaging the actual scientists. If he wants to write science fiction, great; is entertaining.

But pretending to pass fantasy as science in the way he does is not Ok because some people cannot tell the difference. Is the opposite of education, with the aggravation that he is making money out of it.

geijoenr··on Chibicc – A Small C Compiler
I know about this project for long time and in my opinion is an excellent educational resource. As an exercise I re-targeted chibicc to z80 without any problem and it was lots of fun. Now I am trying to write an optimizer on top of it.
geijoenr··on How to Escape Scientific Stagnation
"In a working paper published last year, Chiara Franzoni of the polimi Graduate School of Management and Paula Stephan of Georgia State University look at a number of measures of risk, based on analyses of text and the variability of citations. These suggest science’s reward structure discourages academics from taking chances"

I believe the focus should be in making more basic science affordable to private parties where the incentives for innovation are more clear. Scientific instruments and equipment are incredible expensive, taking action to make them affordable and within reach of more startup companies would definitely have an impact.

geijoenr··on Volkswagen develops hydrogen car that can travel 2k kilometers on one tank
Some time ago I saw a presentation from the chaos computer club where an expert on the matter explained there is a lot of misunderstandings about hydrogen technology as an energy source and how is gonna useful for society and why it is necessary.

In a nutshell some industries that currently rely on natural gas cannot switch effectively to electricity, hydrogen seems to be the only solution at the moment.

Regarding transportation, it seems to be widely accepted that hydrogen is not an efficient solution for small vehicles. There may be some cases where it makes sense (heavy trucks, train locomotives), but overall it doesn't seem like anybody expects hydrogen cars to be mass produced.

geijoenr··on Illegal host, electric shocks, slugs, leaks and no support – How Airbnb failed
I was an enthusiastic user of Airbnb until I faced the reality of the platform on a trip to Seul. After being offered to sleep in what looked like a maintenance closet because the room I had booked was no longer available for the first time contacted Airbnb support. Apart of the fact that the experience was infuriating and frustrating, I am pretty sure 80% of the time it was a bot replying my messages not a support agent. I never got a full refund and I decided it was not worth the trouble, since then I just book hotels.
geijoenr··on Managing and using ONVIF IP cameras with Linux
The market for security cameras is very old fashioned and plagued with proprietary implementations. ONVIF is the standard that allows interoperability with desktop Video Management Systems and other devices, is the protocol that allows to glue together end to end systems.

Some alternatives are starting to appear, but this is an industry that moves really slow. Things only seem to happen when a new player disrupts the market and starts taking market share, as AXIS did with cheap IP cameras back in the day.

geijoenr··on Ask HN: 10k hours rule to master anything. Could I switch career when I am 43?
I have the feeling is in midlife when people switch careers, so 43 doesn't sound strange to me.

You have to be ready to take an income cut though, at least at first. Other than that, I don't think you should be afraid.

That 10k hour rule is stupid. Talent is what makes the difference, either you have it or not. Regardless, it has nothing to do with switching jobs, most people moderately suck at what they do and make living and live happy lifes.

geijoenr··on Rustaceans at the border
I believe Rust will benefit from the reality check that kernel development represents.

Kernel development is hard, and bullshit doesn't go very far in that context. Success for Rust in that environment (with some changes along the way) will be a proof of value.

geijoenr··on It’s time to admit quantum theory has reached a dead end
For some time already we are in an "epicyclean phase" of physics, trapped by the extraordinary predictive success of Quantum Electrodynamics and still using mathematical methods devised in the 19th century (variational calculus). This has lead us to the current situation, with extremely complicated theories at the limit of human understanding that bear no new results. It will take a modern day Copernicus to come up with a new view of physics, that will result in simpler, more productive models, to take us out of the local maximum we are in.
geijoenr··on Vijayanagara – The Last Emperors of South India [audio]
Also my favorite history podcast, the video versions are also really good. Very high production quality, and a riveting narration that provides a broader historical context while giving details about the life of the individuals at the time.
geijoenr··on Consciousness is supported by near-critical slow cortical electrodynamics
This appears to be an indication of a new phenomenon correlated to criticality in cortical electrodynamics, that also correlates to consciousness as we understand it.

It looks to me is a huge step, because even the result is so far empirical, the first step to understand anything is being able to measure it.

geijoenr··on Boston Dynamics’ Stretch robot can move 800 heavy boxes per hour
Finally Boston Dynamics is releasing a robot that looks like a regular industrial robot.

It seems the pressure to generate sales is forcing them to produce more down to earth products that can be marketed easily.
