AlEinstein··on iOS 13 often reloads background apps, loosing unsaved data
TechCrunch says a fix is out: https://techcrunch.com/2019/11/07/ios-13-2-2-fixes-bug-that-...

It’s dismaying how much Apple have taken their eyes off the ball when it comes to software quality. They used to have such a great reputation.

AlEinstein··on Fast Markov chains in ~20 lines of sh, grep, cut and Awk
Which makes it a valid reference for bash.
AlEinstein··on 'Greta Shaming' Photos of Climate Activist Used to Deter from Using Plastics
I hope the people using photos of Greta to shame people into not using plastic utensils have provided an alternative.
AlEinstein··on “May You Live in Interesting Times”
Most people here in Australia have never heard of the Australian Shepherd breed of dogs.

AlEinstein··on Jack Ma Says 12-Hour Work Week Could Be the Norm
Just conditional mood rather than subjunctive I think.

AlEinstein··on Visa, Mastercard, Stripe, and eBay exit Facebook’s Libra project
Exactly this. Facebook will definitely move forward with some kind of payment system. Libra would have been fantastic for them if it had worked out but it was never their only option. They won't give up on Libra yet though.
AlEinstein··on C++ Ecosystem: Compilers, IDEs, Tools, Testing
Second this. I've found IntelliJ to be much faster on large codebases.
AlEinstein··on The Ties That Bind Facebook's Libra
I like to hate on Facebook as much as anyone but there's a fairly obvious explanation for this situation: of the 100 or so organisations that initially expressed interest, the 27 organisations that have so far formally joined are more aligned with Facebook. It's an easier decision for them so they acted more quickly.

With PayPal pulling out and governments expressing concern, it will come down to what well known financial institutions like Visa and Mastercard decide to do.

If they still sign on, I'd hope the balance will be much better by the time they hit the target of 100 founding members. Time will tell.

It'll be interesting to see how far Facebook can push this if other organisations bail out.

That said, I don't for a moment believe that Libra exists for the greater good.

AlEinstein··on Collapse OS
> As for scavenged parts, you're going to need a warehouse of manuals and datasheets, eh?

You're right! As a thought experiment, let's say I download CollapseOS and then switch off my internet.

I have in my house a normal complement of electronic devices. I have a soldering iron, some wire etc. I assume if I start taking things apart I'll find some Z80s. Those Z80s will be living on boards with clock chips and memory etc. Where do I even start?

AlEinstein··on macOS no longer allows changing wifi mac address
Thanks. As a vim user I’ve been assuming the new macbook pros are a non-starter.
AlEinstein··on Zachtronics: Ten Years of Terrible Games (2017) [video]
I totally get what you're saying. For x86-64 I recommend Ray Seyfarth's book: http://rayseyfarth.com/asm/

But I can't help suggesting you try TIS-100. It's genuinely enjoyable and not like regular assembly at all.

AlEinstein··on macOS no longer allows changing wifi mac address
Note that this violates the macOS licensing conditions unless you're running on Apple hardware.

Honest question asked in good faith: Are you a developer? What's it like not having an escape key or function keys?
AlEinstein··on Zachtronics: Ten Years of Terrible Games (2017) [video]
If you've not heard of TIS-100 then, given that you're currently on a site called "Hacker News", I heartily recommend it to you: http://www.zachtronics.com/tis-100/

Also excellent is Shenzhen IO: http://www.zachtronics.com/shenzhen-io/

AlEinstein··on A function that represents all primes
In a sense, this function isn't that interesting; It's just a way of encoding the prime numbers into a real number.

However, one interesting aspect is how efficiently this particular function works for the prime numbers. The function doesn't work for Fibonacci numbers, for example.

Still, it takes 113 bits to encode the primes up to 100, which can trivially be encoded with 100 bits so...

AlEinstein··on Wolfram Rule 30 Prizes
Would you mind providing a little more detail of your reasoning?

For example, say that someone shows that the most efficient algorithm for computing the value (0 or 1) of the central column of the nth row of rule 30 starting with a single 1 cell (i.e., the system under consideration for the prize) takes time n^2. Wouldn’t one then say that the complexity of the calculation is O(n^2)? One couldn’t say that it’s O(n), surely?

AlEinstein··on Why I'm Worried About the Repo Market
Looks fine on my iPhone.
AlEinstein··on WARP is here
"due to some unspecified magic your network performance will increase"

In this post, they say that routing over cloudflare's network can be up to 30% faster because they maintain more efficient routing information than the public network:

AlEinstein··on The exponential function is a miracle
On the face of it, if someone told me a series converged on a small value like -0.4, I wouldn't expect to encounter 43 million along the way.

It's easy to dismiss things as uninteresting but HN is a forum for nerds and I'd conjecture that things like this are interesting for that group.

Surprisingly good performance for the C# implementation!
AlEinstein··on The beauty of Japan's lonely vending machines
This still happens in Australia too. The primary reason to do it this way is that you don’t need a person standing there all day to sell items. A working farm cannot spare a person full time.

I imagine that farms stop the practice when it’s no longer profitable due to dishonesty and theft. It’s only a small secondary source of income in any case. The main income is wholesale anyway.

The article addresses this question.
AlEinstein··on RSA is a fragile cryptosystem
Well that title made me click on it and now I’ve bookmarked that page in case I ever feel the urge to implement my own crypto using RSA. Or at all for that matter.
AlEinstein··on Nobody talks about the real reason to use Tabs over Spaces
But you still haven't said what's dim witted about it.
AlEinstein··on Nobody talks about the real reason to use Tabs over Spaces
There is no logical coherence to this statement. Just because there have been proponents of both sides of a debate for many years doesn't mean that a new argument is invalid.
AlEinstein··on Why Continuations Are Coming to Java
Speaking as a dev who started with Java 1.2, I actually much prefer to write code that doesn’t rely on magic unseen effects.

The only exception to this is dependency injection via annotations but for god’s sake use it in moderation.

But then I still prefer to write for loops rather than streams because I know what the jit compiler is doing.

AlEinstein··on macOS Catalina, 64-bit, 32-bit, and related Questions
I don’t know what to tell you. Every time I launch CS6 on my Mac it tells me that it won’t run on Catalina.

I have no reason to believe that’s not true.

I think it’s quite possible that when Adobe says “64-bit” they’re not saying exactly the same thing that Apple means. I’m no expert with macho binaries and MacOS library linking.

AlEinstein··on macOS Catalina, 64-bit, 32-bit, and related Questions
Unfortunately for people who never switched to the subscription model, the CS6 updates stopped at 13.0.6.

You need 13.1 to launch in 64-bit, which is only available to CC subscription holders.

Edit: it seems that at one time it was possible for non-CC license holders to upgrade to 13.1 but it doesn't work anymore.

AlEinstein··on macOS Catalina, 64-bit, 32-bit, and related Questions
MacOS has supported 32-bit apps and 64-bit apps for years. I don’t know why Apple has decided to drop support for 32-bit apps.

I still use Photoshop CS6 because I never signed up to the subscription model so if I upgrade to Catalina I won’t have Photoshop anymore (unless I run it in a VM).
