I love perl, but I am strongly convinced that strong typing is mandatory for code maintainability. e70838@gmail.com

reacweb··on Some scientists are serious about resurrecting zeppelins for cargo
We do not produce crude oil any more because bacteries are more efficient at digesting dead trees.
reacweb··on What is energy, actually? (2011)
In the not so distant future, energy could become abundant thanks to solar energy. On the other hand, physical resources (rare earths but also the molecules contained in oil) are limited. I think it is more important to seek better recycling, reduce waste than to reduce energy consumption.
reacweb··on GitHub satanically messing with Markdown – changes 666 to DCLXVI
I am working in ATC (air traffic control). Controllers prefer a dumb tool with easy to predict deffects (like STCA) instead of a smart tool with infrequent random failures. Simplicity is underrated.
reacweb··on Run an Internet Speed Test from the Command Line
Maybe MB/s rather than Mb/s. The ratio is 8.
reacweb··on More Intel speculative execution vulnerabilities
Or like java applet. Oracle has killed java applet by not handling security issues in a responsible manner.
reacweb··on German government expands subsidies for electric cars
My brother has one. He always uses electric first.

reacweb··on Fifty years ago, the internet was born in Room 3420
I was student just before https://en.wikipedia.org/wiki/Eternal_September. I remember using a lot gopher (https://en.wikipedia.org/wiki/Gopher_(protocol) ). There was some hype around IRC. Mosaic has arrived a bit latter. At that time everyone was discussing network applications. We were playing sun mazewar, xrisk and other connected games (like https://en.wikipedia.org/wiki/Internet_Go_server). We were using xarchie to find software. I was using xhtalk to chat with remote friends. Chess games between two remote players (single threaded X application managing two displays), remote administration were common student projects.

IMHO, if Tim Berners-Lee had not invented HTTP, someone else would have build something else to improve over gopher.

reacweb··on Space: A Major Legal Void
I think it is a bad mindset. Laws shall not be seen as hindrance, but as beneficial for all.
reacweb··on Italo Calvino, The Art of Fiction No. 130 (1992)
I can not judge for all languages, but the french translation of this book is excellent.
reacweb··on Firefox is getting language translation
I use it since 2 years, mainly for French->English and occasionaly for English->French. I love it. It understand very well idioms and propose excellent translations. Even for traduction of single words, it is far better than google.
reacweb··on New Study Documents Depleted Uranium Impacts on Children in Iraq
All these images are terrible, but it doesn't match my understanding of radioactivity. I thought the lessons learned from Hiroshima and Nagazaki was that radioactivity was causing very few mutations (far less than expected), but instead was causing mainly sterilities. I am not an expert, but teratogene effects are generally caused by chemical products. If uranium is similar to lead, it should cause neurologic diseases, not this kind of pictures.

I do not want to minimize the consequences of war, but this article has no plausibility.

reacweb··on LoCHAid – An ultra-low-cost, affordable and accessible hearing aid device
I can ear the compressed track far far better than the uncompressed one. Should I consult a doctor ?
reacweb··on Ask HN: What are the most fundamental books on computer science?
Structure and Interpretation of Computer Programs (), Introduction to Automata Theory, Languages and Computation (Hopcroft Ullman), don knuth's art of computer programming, Tanenbaum's Modern Operating Systems, Compilers: Principles, Techniques, and Tools5 (Aho Sethi Ullman)
reacweb··on My Favourite Git Commit
Hidden characters again. The answer on stack overflow I am the most proud: https://stackoverflow.com/questions/41061400/perl-join-strin...
reacweb··on Stupid Unix Tricks
In bash, there is the build-in command named "command". I have used it for the same purpose, like in:

    command -v brew >/dev/null && brew install jq
reacweb··on Bags of debris from Fukushima disaster swept away in typhoon
I think the $2.4 trillion of https://en.wikipedia.org/wiki/Financial_cost_of_the_Iraq_War is more trustworthy.
reacweb··on My Letter to the Editor of New York Times Magazine
Flying is boring when everything works well. I remember a story from a friend, a pilot of an airline that was going to sell all its aircraft of a model. 6 month before the sell, the preventive maintenance was reduced to only the legal minimum. In each flight during this 6 month, my friend has encountered technical issues (sometimes as severe as a broken reactor). IMHO, the role of a pilot is to keep a cool head to analyze faults with sometimes slight symptoms and find the right answers occasionally in opposition to the manual. That's also why I want the pilot to be in the same aircraft as me (no remote piloting).
reacweb··on Some corals regrow after 'fatal' warming
If humanity is the disease, will it kill the body or leave both alive in symbiosis ?
reacweb··on Guix Reduces Bootstrap Seed by Half
I do not understand. When I have started on linux, 25 floppies were enough for a full installation (including latex and X) on my big HD (120MB). How a striped down version of bash, coreutils&co and guile could require 120MB ?
reacweb··on Do you have a problem? Write a compiler
Why not using expect directly ? For one of my most complex setup, I have a perl module (using Expect) that is used by all my test scenarios (perl scripts).
reacweb··on This To That
Yes, some chemical details about how each substance works would make this site fabulous.
reacweb··on Saudi Attack Makes Electric Vehicles Even More Important
Yes building an electric car requires more energy than building a conventional vehicle. According to https://www.quora.com/How-much-energy-is-required-to-build-a..., this requires 2.1 year to amortize the difference.
reacweb··on Saudi Attack Makes Electric Vehicles Even More Important
The overall losses between the power plant and consumers is in the range between 8 and 15%. An electric motor typically is between 85% and 90% efficient. Conventional gasoline vehicles only convert about 17%–21% of the energy stored in gasoline to power at the wheels. State-of-the-art fossil fuel plants at 46% efficiency. Using average values gives a ratio of 46x0.885x0.875/19=1.87 (electric almost twice as efficient). This calculus has not taken into account transport and filling the tank and older fossil fuel plants (maybe they compensate each others).
reacweb··on The Distribution of Users’ Computer Skills: Worse Than You Think (2016)
A video to teach me about UI ! It is well known that text is a lot more effective than watching video.
reacweb··on Kiss – A Linux distribution with a focus on “less is more”
Thank you very much. The work seems very complex. At the moment, I am at work on a windows PC. I have exceed and xming started and I have a toolbar with around 70 putty shortcuts with X11 forward. I am using them all the day long. At my previous job (using HP servers), it was a similar setup (with only 5 shortcuts).
reacweb··on Kiss – A Linux distribution with a focus on “less is more”
Before deciding to try a new distribution, I want to know which important application it supports or not. I assume it supports usual stuff like ssh, vim, emacs, python, ruby, node, but does it support chrome, firefox, visual studio code, docker, virtual box ?
reacweb··on Kiss – A Linux distribution with a focus on “less is more”
X is widly used since 30 years. Its configuration (and security model) is well documented (xorg.conf). It is as simple as launching the X server using a simple command line and being able to connect any client (even remote) thanks to a single environment variable (DISPLAY).

How do you launch a wayland server and how do you forward "display" (ssh -X or -Y) to launch a remote application ?

reacweb··on Stripe’s new funding round values company at $35B
And thank you also for your CTFs. I almost finished CTF 2 (I had the 3/4 of last password) and I learned a lot during this CTF. I am very proud of my T-Shirt.
reacweb··on Stallman's final interview as FSF president
rms writes and talks a lot. This gives many opportunities for his opponents to find ways to attack him. The main point of rms is freedom. Freedom is a right than can sometimes benefit to evil people. Defending freedom does not mean we defend evil people. I don't see anything reprehensible in the comments of rms, just opportunities for his opponents to use this fallacy.
