mfgs··on Why You Should Take Any Vaccine
I think the parent comment was intended to be sarcastic.
mfgs··on Tesla spent $1.5B in clean car credits on Bitcoin
How would a company like Tesla "store" such a large amount of cryptocurrency? Who would hold the private key(s)? Surely not one person, and if not, how would they be distributed in a safe way that both prevented insider theft and provided redundancy to prevent lock out?
mfgs··on A visual guide to SSH tunnels
Yep, but it works well for me in landscape view.
mfgs··on Zoomquilt (2004)
Definitely putting this on the projector next time I have a party.
mfgs··on Femtosecond laser writing of glass, including borosilicate, sulfide, and lead
Some interesting photos of what's possible with that technique: http://optofab.org.au/uli.html
mfgs··on AVR support merged into Rust nightly
What does this mean for someone who is quite familiar with AVR but new to Rust? How much of what I can normally achieve in my AVR projects can now be done under Rust?
mfgs··on Monobloc chair
But a lower thermal conductivity will make it feel less hot when you sit on it.
mfgs··on Free Software Foundation Asks Microsoft to Open Source Windows 7
I'd imagine there's too much code overlap with Windows 10 for Microsoft to want to do this.
mfgs··on Letting slower passengers board airplane first is faster, study finds
I just wish people that had to wait 20 minutes for their checked in luggage to be unloaded would stay seated until others had exited.
mfgs··on Show HN: Space Invaders in the URL
Cool! Firefox on mobile doesn't render the emojis though, just long strings of Unicode strings.
mfgs··on Samsung: Anyone's thumbprint can unlock Galaxy S10 phone
That seems unlikely. They surely would've done the most basic testing that would've found a bug like that. The issue here seems to be the addition of the screen cover is making all fingerprints appear similar enough to pass as the same one.
mfgs··on Microplastics found in 93% of bottled water tested in global study
All that carbonic acid can't be great for her teeth.
mfgs··on Giant batteries and cheap solar power are shoving fossil fuels off the grid
Is there a theoretical limit to (current generation) battery capacity, like there is with solar panel power output?
mfgs··on A giant whiteboard for $14 plus nails
For my home desk I used a second hand dining table. It's 2.5 metres long, cost ~$200, and is beautifully finished timber. It worked out cheaper and much nicer than building a desk out of new wood. The second hand market for furniture in my city is amazingly cheap.
mfgs··on PyPI now offers two-factor auth
You won't lock yourself out. I just did a quick test and if you reset your password (via an email link) then you are automatically logged in. At this point you can even disable 2FA. So 2FA is protecting against logging in with a stolen password, but it's not protecting against logging in if you have access to the account's email account.

Whether or not that's the intended behaviour is another question...

mfgs··on Former student destroys 59 university computers using USB Killer device
You'd need opto-isolated data lines. I can't see any common devices having that.
mfgs··on Show HN: Hacking slot machines with a buttonhole camera and brute-force search
Raspberry Pi is slow for image processing. You can probably greatly increase speed if you take smaller images or downsize them before processing.
mfgs··on Drawing fractals in the browser with L-systems and ES6
Nice.

Can L-systems support random variations? The code in the example produces the same fractal each time as the L-system is deterministic.

mfgs··on Loopwheels: A vibration-reducing wheel with integral suspension
Friction and noise aside, it's better to have the suspension built into the frame rather than the wheels. Added weight in the wheels adds to rotational inertia, which is harder to overcome than linear inertia. A rough rule of thumb is one kilogram in the wheels is worth two in the frame for a car in terms of acceleration.
mfgs··on Age of Enlightenment: The Promise of Circadian Lighting
That depends on which hemisphere you're in.
mfgs··on That feel when you can't captcha [video]
If there wasn't a cost associated with completing captchas then wouldn't it defeat the purpose?

mfgs··on The world's first solar-powered train
The train only runs a return route of 3km on flat track. It looks as if the train is battery powered with the batteries being charged from solar panels both on the train and at the station. It seems unlikely that the train alone could hold enough solar panels to keep the batteries charged, even when factoring in time spent waiting at the station. Mains power can also assist in charging the batteries when solar is inadequate (which is possibly all of the time?).

This train was originally planned to be diesel powered but has now switched to electric, I'm guessing due to protest from the local community.

mfgs··on Recycle robot – using raspberry pi and tensorflow
Impressive, it's already more intelligent than half the people in my apartment building.
mfgs··on Comprehensions in Python the Jedi way
In terms of pure readability I find breaking the list comprehensions helps in more complex cases (and is still valid Python), e.g.:

    octets = [bbs[i:i+8]
              for i in range(0, len(bbs), 8)
              if i%2 != 0]
mfgs··on A Book about Qt5
Huh, strange. My standalone build sucked in numpy and PyQt4 (but not PySide) no troubles at all. I did have a minor problem with ctypes (explicitly importing _ctypes was required), but apart from that surprisingly smooth sailing. I have tried Cython briefly but Nuitka seemed a lot easier; just point and go. No modification to the source code needed and I ended up with a nice .exe and a bunch of .dll and .pyd files (including those for numpy and PyQt4). Build time was 30 minutes for a small-medium size application (25000 lines) in Python 2.7.
mfgs··on A Book about Qt5
Lately I've been using Python/PyQt with Nuitka, which transpiles the Python to C++ and then compiles it into a standalone exe + dlls. It (more or less) just works too, very cool indeed!
