avsteele··on Ask HN: Why Is Everything Declining?
Antisocial behavior has been on the rise since the pandemic. You aren't imagining that part. Fight on planes, petty theft, car accidents, murder all up.

Not so sure about the rest of your complaints.

avsteele··on Bitwarden design flaw: Server side iterations
If your first two statements are correct I can't see how the third can't be.

If we choose our password from only ~24 chars then you can get the same effect of 100K iterations form just 4 more characters, or ~1 more dictionary word.

That doesn't seem excessive

avsteele··on Bitwarden design flaw: Server side iterations
I still haven't seen a clear explanation of how the # of iterations scales in relation to password length.

If it is true a few extra characters is as good as having sky-high iterations, the guidance should be on 'forcing' users choose long-enough passwords, not in this nitpicking over the 'right' # of iterations.

avsteele··on Microsoft has laid off entire teams behind Virtual, Mixed Reality, and HoloLens
In my use case the complex, scientific equipment is spread around the world. Low volume though. I planned to offer support remotely rapidly with HoloLens.
avsteele··on Microsoft has laid off entire teams behind Virtual, Mixed Reality, and HoloLens
I really wanted to use HoloLens for remote support. Too bad they never really looked like they would support it for wider use.

We are a small company that sells very complex equipment to labs around the world. The users are smart / PhDs, they just need to be told what to do to fix things when they need an adjustment. This is large physical scientific equipment and the stuff requires 'hands-on'.

avsteele··on Amazon Closing AmazonSmile
In addition to the criticism raised by others: just look at the new list of 'approved' charities. Holy cow. Talk about ineffective altruism!

avsteele··on The Slow Death of Surveillance Capitalism Has Begun
Can a business have its ads seen just in its local geographic area without targeting?
avsteele··on The Slow Death of Surveillance Capitalism Has Begun
The popularity of these services is good evidence to the contrary.

Also you are assuming you can have 'same' service after banning targeting. That remains to be seen.

Also, you could consider disagreeing without being rude.

avsteele··on The Slow Death of Surveillance Capitalism Has Begun
This seems:

Good for megacorps who don't need targeting and can be pay less for ads.

Bad for small/niche advertisers who do need targeting.

Neutral for the vast majority of consumers who don't appear to care about tracking.

avsteele··on FBI Looking for Hashflare Victims
That's fascinating.

It would seem to set up a situation where your incentive, if you suspect a Ponzi scheme, is to quietly withdraw your money early then keep your mouth shut. Unfortunate if true.

avsteele··on FTC cracks down on companies that impose harmful noncompete restrictions
Look, I understand most of you here are on the employee side, but please try and think through how this works in the real-world. And not for mega-corps, but smaller business who have ~0% chance of litigating a trade secrets case.

There are dozens of small optimizations in my tech that where painstakingly discovered through years of research and iterative improvement. These are not cost-effectively patentable.

Even if you believe the trade secrets 'work' do you think companies are going to document every design of optics, electronics, laser frequencies, rf powers? Then if we did then we'd get a series of posts about how onerous the regular confidential info acknowledgement forms are for the employee.

Not to mention, once it becomes 'commonly known' via disclosure, it may not even be protectable anymore.

Non-competes sidestep all these issues. Sure, if they are overly broad its bad, but they have an important role to play.

avsteele··on FTC cracks down on companies that impose harmful noncompete restrictions
Then how would a company protect it's trade secrets?
avsteele··on LearnCPP: Website devoted to teaching you how to program in C++
I am always grateful that people spent their time to create resources like this. This looks good and I would recommend it to someone who isn't a total newbie.

I also find it very interesting to look at the pedagogy of these sites. In the case of this site, it starts with a lot of history and computing. This is common for books, but asking a new user to wade through so much preamble before any 'meat' is asking a lot. In the first part where code is shown/explained:

https://www.learncpp.com/cpp-tutorial/statements-and-the-str...

is a lot of upfront jargon for a newbie to process. ('pre-processor directive')

It does do a good job of showing how to set up visual studio. However these days, a htttp://repl.it is surely a MUCH easier way to get up and running.

I wrote a very small ultra-beginner guide for a young relative to learn C. It gets right into what C code looks like, makes connections to the math they have seen in school, and tries to hold back terms until they are really needed (omitting details where needed)

It isn't polished designed for widespread use, but I think for the truest beginners its better than other guides I found on the web.

avsteele··on I worked at LastPass as an engineer
If linearly proportional then it is approximately equal to one extra character. OK, thanks.

I'm not sure to whom the rest of your response is addressed, this was a technical question.

avsteele··on I worked at LastPass as an engineer
Can someone knowledgeable explain how the number of iterations affects account security for this breach?

OK higher is better sure, but is moving from 5K iterations to 100K per the recommendation a similar precaution to adding 1,2,3 digits to the master password?

avsteele··on A circuit simulator that doesn't look like it was made in 2003
This seems pretty cool, esp for a newbie to know how to put down a circuit.

I use http://www.circuitlab.com and find it to be quite good for laying down parts and doing simulation including time-dependence and with parameters. Very reasonably priced IMO.

avsteele··on Not-so-great features coming soon to Windows 11
Any tips on setting up the firewall to block the MS-generated adds?
avsteele··on Not-so-great features coming soon to Windows 11
We use windows at work because people need MS Office, CAD, and because it is the easiest platform for me to develop desktop apps for our scientific equipment.

Win 10 issues in this vein were a bit annoying but no too terrible

I've been dreading having to move to 11 someday. All the bad parts of 10 get cranked up. We can't even create local accounts (as is appropriate for a single-user / shared machine.)

I have been liking other Microsoft software the last few years. But why are they ruining Windows for any professional use?

avsteele··on Ten Minute Physics
If you want to play with a little demo I made for talking about laser cooling physics go to:

https://zerok.com/demo/

Admittedly it will be a bit hard to follow without the accoupling lecture, but if you zoom in and press the buttons (cool, compress, etc...) it looks cool at least!

(it only performs well in chrome-derived browsers)

avsteele··on People tricking ChatGPT “like watching an Asimov novel come to life”
Yeah its fun. If you ask it do do something but it refuses, you can just retry by asking in the style of a play.

https://twitter.com/adamvsteele/status/1598842550797754368

Honestly I'm surprised why it even refused my first question. But ... "Ve haff ways of making you toc"

avsteele··on Gut epithelial barrier damage caused by dishwasher detergents and rinse aids
The particulate result is dubious from what I've seen

Most people keyed into this from the Vox article:

https://www.vox.com/energy-and-environment/2020/5/7/21247602...

Which links to:

https://www.osti.gov/biblio/1172959

As evidence for the claim that Gas range put out more PM2.5

But if you consult table 3 of that article you will see it doesn't show that at all. The food (especially frying) swamps differences between electric vs gas ranges, which themselves aren't even significant.

avsteele··on New details on commercial spyware vendor Variston
Why do companies like Google and Microsoft not get more aggressive with these semi-criminal-orgs? Couldn't they massively raise the cost of being in this business by by making an example of a few?

Brainstorming:

- Sue them, aggressively.

- Looks for exploits in their own systems and publish their code, making it worthless.

- Publish lists of their owners and employees and/or ban them from Google/Microsoft services.

I'm sure folks here could think of more/better ideas.

avsteele··on We should have Markdown-rendered websites
I love this idea. Hope it gets some traction!
avsteele··on Dotfile madness (2019)
When using .Net 6 I use

  Environment.GetFolderPath( SpecialFolder.LocalApplicationData)
in Windows this maps to

  ~/AppData/Local
An in Linux to

  ~/.local/share
so it is configured well
avsteele··on I asked Signal motivations for SMS removal
This is a fantastic summary.
avsteele··on I asked Signal motivations for SMS removal
I'll say what I said to Edith on twitter:

------------------

This will relegate Signal to niche use.

I don't even know if I will keep it and I've been a booster for years. I'll have to remember which ~5 of my contacts use Signal, and mentally update that list when/if any join?

Can't take on that cognitive load for everyday comms.

avsteele··on Show HN: The Unix Pipe Card Game – teach kids basic Unix commands
Nice. Was trying to print out the programming set for my son, but its too hard to read.

Can anyone get these to printout larger, and where the grey comments are less washed out?

avsteele··on Philadelphia’s diatom archive is a way, way, wayback machine
If you want to see an elemental map of a Diatom you can take a peak at some data collected on one with my company's new instruments.

slide 28

Background: This is SIMS data (https://en.wikipedia.org/wiki/Secondary_ion_mass_spectrometr...). We have a new instrument can perform these analyses at much higher resolution than has been possible historically.

avsteele··on Did GoogleAI just snooker one of Silicon Valley’s sharpest minds?
Those features are not in the same league as the original promise of e.g. calling a business and making a reservation for you.
