Leszek··on Project delays: why good software estimates are impossible
100% confidence in any estimate is impossible, that's what makes it an estimate.
Leszek··on Final features of C++17
Because they still wanted to support some EBCDIC code pages which don't include { or }.

Leszek··on Angular Material 1 will enter a maintenance mode
I think removing the word "deprecated" would go a long way towards making the title less misleading.
Leszek··on Can text in different colors help you tackle the most difficult books?
I'd enjoy an interactive version that could e.g. define variables when the mouse hovers above them. It's a shame that we're still bound so much by the rules of print.
Leszek··on Chromebooks outsold Macs for the first time in the US
> I don't think it's the year of the linux desktop anymore than Android is the year of the linux phone. Sure, there's a kernel somewhere deep, but the userspace is locked-down, weak and anti-consumer.

Perhaps Stallman has a point when asking people to talk about Linux as GNU/Linux.

Leszek··on Stopping All Stations – The Pyongyang Metro
I don't disagree with the general message of your comment, however:

> There is a palpable sense of fear and unease on people's faces, not a smile to be seen.

I'm not sure that if you took a picture on the London Tube or the NY Metro you'd see any smiles either.

Leszek··on AI is transforming Google search – the rest of the web is next
Sure, but transforming a feed-forward neural net into an RNN is also not just a fine-tuning.
Leszek··on AI is transforming Google search – the rest of the web is next
Well, we do know why gradient descent works (for smooth data), at least for finding a local minimum, because finding the minimum is basically what it does by construction. Similarly, we certainly know how back-propagation works, because it's simple calculus, backwards application of the chain rule.

Perhaps what you're trying to say is we don't know why finding local minima of these problems is good at solving the problem?

Leszek··on AI is transforming Google search – the rest of the web is next
I agree with you, but I should point out that adding recursion is hardly "fine-tuning", it's changing the network into something entirely different.
Leszek··on Ncurses Programming How to (2005)
For those who have as much difficulty googling this as I did: https://www.enlightenment.org/about-terminology
Leszek··on Using two-factor authentication for SSH
I don't really understand authy: does it not keep your 2FA tokens in "the cloud" behind a password? Therefore, does this not make them equivalent to a password, and negate the whole point of 2FA?
Leszek··on Animated SVG vs. GIF
That's a very interesting approach, the packing in particular is much better than the usual transparency hack used for GIF animation compression. Using overlayed divs for faux-blitting where canvas is unavailable is also cool, though perhaps somewhat fragile.
Leszek··on When I stopped hearing the voices in my head
I'm curious, since perception is an interesting thing when you can no longer trust your sense: are you certain that you actually heard a fully functioning, never before heard, tunable symphony, or did you simply believe that you were? That is, did the symphony itself exist in your mind, or just your perception of it?

I ask because I often have the experience in dreams, that I experience something which I perceive to make sense until I actually try to make sense of it, whereupon it falls apart. My brain only generates my response to the input, not the input itself, and when queried for the input fails to produce it.

Leszek··on “Dissected Maps” Were the First Jigsaw Puzzles
Interesting that the ~1812 map of Europe is at least 40 years out of date, as Poland appears to have the borders it had before the 1772 partition.
Leszek··on Why Torture Doesn't Work: The Neuroscience of Interrogation
And similarly, torture can be stopped. The time and experience of imprisonment cannot be returned.
Leszek··on Braess' paradox: adding a new road to a city can slow down traffic
This is close enough, it's not quite as clear as the demonstration I saw but it shows the same effect: https://www.youtube.com/watch?v=xiOEYNGV5P8
Leszek··on Braess' paradox: adding a new road to a city can slow down traffic
I once saw a particularly interesting physical manifestation of this paradox (performed I believe by Chris Bishop), where a weight was suspended from two partially elastic ropes, both attached to the ceiling. These two suspending ropes were connected in the middle by another rope. The weight was analogous to the destination, and the ropes were the roads, with the total duration of the route being analogous to the distance of the weight from the ceiling. When we removed the central road (by cutting the connecting rope), the weight paradoxically went up instead of down.

I wish I had a video of this demonstration, it really hammered in the point (for me) that this is a real phenomenon and not just mathematical trickery or electrical weirdness.

Leszek··on Tesla Model S Autopilot Features
It's more likely to be cranked down though, because that's more efficient and people might be less frustrated with slow driving if they can kill time on their phones during the drive.
Leszek··on Chromecast + NFC
Also see: Amazon Prime Video.
Leszek··on Kilogram conflict resolved at last
Also known as Planck units

Leszek··on 81-year-old man driven to death by phone scammers
I made the mistake of reading this book once: the rest of it is similarly awful.
Leszek··on Nap desks
I tried napping in one of these once: it was pretty uncomfortable, since you're still sitting fairly upright (imagine an airplane seat tilted backwards), and I find the pod to do little for me in terms of blocking the surroundings, especially noise.
Leszek··on Code to transform Hillary's emails from raw PDF documents to a SQLite database
I stand corrected on that one, I'd personally only ever heard of her referred to by her full name, but that's just my own ignorance.
Leszek··on Code to transform Hillary's emails from raw PDF documents to a SQLite database
To be fair, there was another famous Clinton that could make this confusing. I've never heard of Condoleezza Rice, Sarah Palin or Angela Merkel being called by just their first name, although I admit that I don't often hear them being called by just their last name either (maybe except Merkel).
Leszek··on Airbnb, My $1B Lesson
It's very interesting hearing a story from the VC's side. One always reads about the trials and tribulations of startups trying to raise capital, but I've never considered that there might be similar issues and competition on the investors' side.
Leszek··on After Moore's Law: how phones are becoming open-source
I agree with Linus Torvalds about Moore's law:

"It's like Moore's law - yeah, it's very impressive when something can (almost) be plotted on an exponential curve for a long time. Very impressive indeed when it's over many decades. But it's _still_ just the beginning of the "S curve". Anybody who thinks any different is just deluding themselves. There are no unending exponentials."

Leszek··on The Max Headroom TV Hack
This is the thread that the article mentions.
Leszek··on Introducing the San Francisco system font
So... what does it look like? The font on that page is Myriad, and I can't see link to a preview of the font itself.
Leszek··on Terms of Service, Didn't Read
Fair point, but in that case free/open source is irrelevant: one could equally well build a closed-source app without a ToS, or an open source app with one.
Leszek··on Original Star Wars script discovered in UNB library
It is, but that one is actually the reference to Luke Skywalker's name in some of the earlier drafts. See, for example:
