drpixie··on Hynix launches 321-layer NAND
Title should probably be "Hynix launches 321-layer NAND RAM".
drpixie··on Gentle Guide to Self-Hosting
Yup - as they say, "the cloud" is just some else's computer.

It's not so hard to genuinely self-host. You just need a reasonable ISP who is willing to open your connection, and to be sensible about securing your systems.

drpixie··on What is the longest known sequence that repeats in Pi? (homelab)
I suspect not. Pi is known to be irrational, and repeating sequences are known to be rational. So pi cannot be truely repeating.
drpixie··on Show HN: I Made a Website for Problems
Could be interesting, but I'm not going to bother signing-up just to see more than a very slim homepage. That's a fail from me :(
drpixie··on The Vala Language (2017)
>> The existing ones are all deficient in rather serious ways

But most of the new ones look and behave just like the old ones - but with slightly more awkward syntax to allow for some special "feature" dear to the authors ;)

I routinely check out the various new languages mentioned on HN and Lobsters. While plenty of languages are new to me, I'm yet to see any feature that is new to me :(

I appreciate the work that goes into any language, but the stream of "new" languages feels like a stream of tweaks and rearrangement. It's disappointing. Most new languages come across as "like language X but with feature Y".

Reminds me of all those "Airbnb for X" proposals from a few years ago:)

drpixie··on The Vala Language (2017)
You're right of course. I was thinking that human languages change naturally while in use.
drpixie··on The Vala Language (2017)
Aarrggghhh. Why do we insist that projects/systems/languages must be continually changing and evolving?

Shouldn't there be room for a system that just does the thing(s) is does well? Why do we need to be continually tweaking? Adding increasingly obscure "features" and new bugs?

Unlike a human language, a computer language isn't "dead" when it stops changing. It is dead when nobody is using it. These are very different criteria.

drpixie··on Google removed Organic Maps from the Play Store
Australia "up-to-date commercial data like stores and their opening hours" is about all that appears on Google Maps :(
drpixie··on I put a toaster in the dishwasher (2012)
Love the distinction between "Conventional Wisdom and Conventional Ignorance" :)
drpixie··on Launch HN: Airhart Aeronautics (YC S22) – A modern personal airplane
> they almost always culminate in the pilot failing to control the airplane

"failing to control the airplane" is a little like saying everyone dies of heart failure. Yes their heart stopped - but why!?

The real cause is somewhat earlier. Why was a normally competent pilot in a situation where they no longer adequately controlled the aircraft?

Improve avionics - great. Improve situational awareness - really helpful. Handling should be way down the list - it becomes quite intuitive very quickly.

drpixie··on Launch HN: Airhart Aeronautics (YC S22) – A modern personal airplane
Minimal traffic? An ATPL pilot here. Fly into any major airport and you'll see that it can be REALLY BUSY. The system is based around separation down to about 1 minute. Major airfields are all traffic limited (hence "slots").

1 minute might seem like a lot when you're walking or driving, but when coming in at 200mph in something that weights hundreds of tons ... I want that guy 1 minute ahead of me off the runway ;)

And that's considering that existing traffic is of similar speed and ability. Adding slow, small, low-performance aircraft to the mix makes things very interesting ;( Then add low-experience pilots who have to stop and think about procedures, actions, radio calls ...

permission to back their car out of their driveway - It might be different if those cars cost $100M-$300M. A tiny bingle is very expensive.

drpixie··on Ask HN: Am I crazy or is Android development awful?
Strong agree - it's horrible. I can't get past the enormous amount of boilerplate code that's required to do anything - even the proverbial Hello World.
drpixie··on The Chorleywood Experiment (2023)
In Australia "baked in store" actually meant baked in Ireland, frozen, shipped to the other side of the would, and warmed-up/finished-off in an oven at the supermarket!
drpixie··on Just Be Rich (2021)
Why not something a little simpler, like a universal sales/VAT/transaction tax offset by a UBI. This simpler model provides fewer opportunities to build or exploit loopholes.

The universal tax would be at a relatively low rate, because it would apply to all transactions. And the UBI compensates everyone for the tax on essentials.

drpixie··on Beating the Compiler
Can you give an example?

In general, searching any significant space is very slow, applying heuristics is much quicker.

drpixie··on Rounding Percentages
And a really bad example - apps from a certain large search/email/ad company where the progress bar moves even when nothing is actually happening ;(
drpixie··on What You Get After Running an SSH Honeypot for 30 Days
Yes - Anyone who's FAQ answer to "How to avoid being scanned" is "We don't have an opt-out, you must block all these addresses" isn't behaving like a legit business.

"Nice network you've got there."

"We noticed something might be open. We're not telling you what it is."

"It would be a pity if something happened to your business."

"Give us lots of money."

Sounds like a movie strong-arm thug.

drpixie··on Heat Death of the Internet
> calling it "heat death" makes me think how the whole thing is steadily unraveling

"Heat death" seems especially appropriate when talking about google results being pages of nothing but scraped results of SEO rated pages of scraped results, ... Or youtube showing ads for ads for ads...

And how long before our AI results are built primarily on previous generations of AI results. Turtles all the way down to ... mindless nothing :(

drpixie··on Crazy Charlie's Window
I really hope that someone, somewhere can tell us the origin of the window ;)
drpixie··on Monowheels: Vehicles with Insufficient Wheels
> Vehicles with Insufficient Wheels

Nothing insufficient about monowheels. Should not the title be "When one is sufficient"?

drpixie··on Ask HN: Why does an infinite universe mean a duplicate of me?
Sounds like the start of a proof by contradiction that the universe is not infinite, merely very, very, very large :)
drpixie··on Linux fu: getting started with systemd
> Like many long-time Unix users, I’m not a big fan of systemd. Then again, I’m also waiting for the whole “windows, icon, mouse, pointer” fad to die down.

I like a writer with perspective :)

drpixie··on Cow Magnets
In Australia, a "chick magnet" is a large attention seeking car owned by a young guy. It is intended to attract girls (chicks). It always has a serious stereo, and probably has a modified exhaust.

Young guys spend a fortune on their "chick magnet", presumably to indicate that they could spend a fortune on potential girlfriends. The desired outcome often fails to eventuate - many "chick magnets" are only driven up and down the main street occupied by the single owner and his single friends ;)

drpixie··on Did any processor implement an integer square root instruction?
So many people assume that everything that came before they were at school was primitive, and barely chugged along :)

A little reading shows the opposite. Most of our smart ideas were already used in 1940s/50s/60s computers, and are recycled on our fab new chips!! Pipelining, out of order exec, multiple cores, etc.

That old-time hardware might have been a bit "chunky" but the architectures used some very smart techniques.

drpixie··on What makes housing so expensive?
Yes - normal people normally pay everything they can afford on their house, so it's peoples' income that determines house prices.

Interesting that almost everyone is happy to drive around in a mass produced car, precisely the same as 10,000 other vehicles. And cars, although much more capable, cost (relatively) much less than decades ago.

But almost everyone wants their house to be special and unique, and pays whatever they can to that end. I don't see it as housing supply driving costs, so much as money supply.

drpixie··on Ask HN: What is the most useless project you have worked on?
Different but similar. I once wrote a trivial lotto number selector app, at the request of some colleagues. It just emitted a few unique random numbers. Silly but why not.

They hated it.

I added moderate, random delays before emitting each number. They loved it, and used it every week for quite some time :)

drpixie··on Bitcoin tumbles $5000 in 24 hours as interest rates jump
I would have thought a $5k change was normal random bumps for bitcoin ;)
drpixie··on Show HN: Faster-than-light ping (April Fools')
Very nice. Takes a special mind to think about tweaking the contents of ping packets :)

Now, by rights, you've shown that I shouldn't trust anything I receive from anybody.

drpixie··on Xzbot: Notes, honeypot, and exploit demo for the xz backdoor
Sounds like (another) good reason for IPv6 - your box can have many, very obscure addresses :)
drpixie··on -2000 Lines of Code (2007)
When I managed software for a large corporate, I kept a box of pencils on my desk.

For around 1/2 the information requests that came through the department (always very important, we need the info now, it will save/make big dollars) the obvious answer was "Work it out from the info you already have. You've got a calculator and spreadsheet - would you like a pencil?"

Better to avoid the system handling X than having multiple special cases bulking up the systems, most of which only get used once in a blue moon. No one knows the special cases/programs are there, or what actually do. Even if well documented, no one spends the time required to know what's available. So most of those special features are actually waste of time.
