stolk··on Ask HN: Who is hiring? (June 2023)
The 3dverse link'd in has: "There are no jobs right now."

Also no careers link on your website?

stolk··on Network bandwith statistics in your terminal: ifgraph
Light-weight tool to graph bandwidth use aggregated over multiple network devices. For Linux. Zero dependencies.
stolk··on The $8 Linux Computer
Heh... I do feel like a dinosaur at times.

Do you have a suggestion for a better platform?

stolk··on The $8 Linux Computer
OP here...

My first linux computer was a 33Mhz i386. I can't remember the amount of RAM, but it must have been 2MB or maybe 4MB.

This thing has 64MByte of RAM, after login, 44MB of it is free.

stolk··on The $8 Linux Computer
OP here...it got a little better with a patched picoprobe.

I wrote up part 2 here: http://thelittleengineerthatcould.blogspot.com/2022/12/the-8...

But yeah, not plug-n-play. I still have to find out how to get network or SD-Card.

stolk··on The $8 Linux Computer
Yes, but those are microcontrollers. This is a computer on a chip with mmu, and three cores, 64MB ram.
stolk··on The $8 Linux Computer
It is a SoC with MMU. It just looks like a MCU.

64MByte RAM, (45MByte of it free after logging in.)

stolk··on In Defense of Dumb TVs
Does this cause issues with HDCP2?
stolk··on Show HN: Monitor CPU frequency scaling under Linux
Yesterday, I released freqtop.

It is a linux tool that runs in the terminal and shows a live view of the frequencies that the CPU cores are scaled to.

Core frequencies in linux are dynamically set by a governor based on the load.

stolk··on The world could soon run out of space to store oil. Prices may plunge below zero
Sweden at one point, had marginal income tax rate EXCEEDING 100% for some people.

Look it up. It is very hard to believe, but true. That exceeds communism.

102% income tax rate, people... https://en.wikipedia.org/wiki/Pomperipossa_in_Monismania

stolk··on Gathering Intel on Intel AVX-512 Transitions
Would disabling “Intel Turbo Boost Technology” be advised to avoid this?

If it never uses turbo, it should not suffer the transitions?

stolk··on There is more to high house prices than constrained supply
The double star * * 'power' operator was removed from my text.

(925/650.0) raised to the power (1/20) is 1.0178

1.0178 raised to the power 20 is 1.42

stolk··on There is more to high house prices than constrained supply
Your personal rent example: 650 -> 925 in 20 years is very meager growth, well below inflation: 1.78% per year.

So yes, less than 4%. A lot less.

>>> (925/650.0) (1.0/20)

1.0177975914387338

Note that 20 years of +1.78% per year does +42% compounded.

>>> 1.0178 20 1.4231442772353857

In real money, the rent for your place has gone down, not up, ignoring the furnishing.

stolk··on Most stockmarket returns come from a tiny fraction of shares
Does this statistic consider cap gains only?

Or did the author take dividend into account?

I'm not surprised that cap gains are concentrated in a few stocks, but overal wealth creation? I have my doubts.

stolk··on Reality has a surprising amount of detail (2017)
It sounds like it would be far easier to pour concrete steps instead? Gravity will take care of making each step perfectly horizontal, at least.
stolk··on Her six-hour commute each day seems crazy, but her affordable rent is not
I would go home for weekends, and during the week sleep in a van in the parking garage. This works even better if you can make your work week 4 long days, then 3 day weekend away from the city.
stolk··on Everything Is Crazy and the Markets Aren’t Freaking Out
And why wouldn't the stock market go up?

Companies are growing their revenues, and are making healthy profits.

A good chunk of those profits are paid out as dividends. If dividend yield is much higher than those tiny interest rates, why wouldn't you borrow money, invest, and enjoy dividends? It's the rational thing to do, and hence, demand for stock is up, stock price is up. But as long as the corporations keep distributing, it makes sense.

Real Estate. I bought into Vancouver's RE bubble. Bubble still grows though.
stolk··on [dead]
Well, even if it is not impossible today, the likelihood of making it big approaches zero.

In 2010, people were hungry for iOS games, but the supply of quality games was limited. There were few people who were able to write good OpenGL ES2 apps. Now, there is the Unity engine and others.

For several years now, the market has been saturated. Years ago, I already saw a 1000 new games per week in Apple's iOS store. I suspect this number is larger now.

The one-man app-store hit days are over.

Also... Apple no longer gives you free visibility in "new releases." Worse... it makes you bid on the search results (!!!!)

stolk··on [dead]
Mobile games, iOS in 2010, later on Android.

Spent it on expensive RE though, so no longer in chequeing account.

stolk··on If you’re renting a city apt. without a car, 16% of your rent pays for parking
So what if you don't have a car: No car, but a parking space assigned to your condo/apt? Just rent it out to a neighbour with two cars, and you get those $150,- per month right back. Problem solved. I rented an additional space in my building for my motorcycle. Happy renter, happy parking-space-landlord.
stolk··on How 'OK' took over the world (2011)
In French, "au quai" means "in the harbour."

Cargo in the harbour, is not lost at sea, or in transit.

Instead it is safe and sound, or O.K.

stolk··on Windows Phone Developers: Just Let It Go
So about UWP: Browsing the Microsoft website, I see that you can develop in C++. But can you do OpenGL apps with UWP? Or is Direct3D the only way to do 3D for the UWP platform? If it is, it kinda makes porting from Android/iOS/Linux to UWP too hard to be practical.
stolk··on Why I switched to Mac after being a long time Windows evangelist
Windows 10 Creator's edition was incredibly unstable for me: after the upgrade, it would hang within minutes after boot. Each and every time. This went away after upgrading firmware of my Samsung SSD EVO 840 drive. But yeah, windows has never been an industrial strength OS like QNX and UNIX are.
stolk··on AMD 16-Core ThreadRipper Enthusiast CPUs to Reportedly Utilize 4094 Pin Socket
The i9 is most definitely something new.

It is the first desktop CPU to bring AVX512. If the code is designed for it, that by itself doubles the perf compared to AVX2 CPUs.

I look forward to porting my algorithms to 16 wide SIMD.

stolk··on Why F.E.A.R.’s AI is still the best in first-person shooters
Yes, all actions have a cost associated with it.

You can use it in different ways: like you describe: have some agents prefer certain actions, different from the preferences of other agents.

The way I use it is to adapt to the environment. For instance, I make walking over to let's say an apple, less costly if the closest apple is near.

stolk··on Why F.E.A.R.’s AI is still the best in first-person shooters
AVX is used for exactly this: GOAP.

The search space for the plans is ridiculously large, so testing pre-conditions needs to be insanely fast. With AVX, you get to test up to 256 boolean preconditions in one go!

To give you an idea about search space: the Orcs have a repertoire of 115 possible actions. Stringing together a plan of let's say 12 actions (some plans are longer), gives 115 12 possible plans. That is a scary big number: 5350250105473711181640625

A* helps guiding the search through this space, but can only do so much. So every A* operation needs to be as fast as possible.

stolk··on Why F.E.A.R.’s AI is still the best in first-person shooters
It crashes? Can you email b.stolk at gmail the call stack? You should see a window with crash info if it crashes. Thanks.
stolk··on Why F.E.A.R.’s AI is still the best in first-person shooters
Playable right now. It's a free download from Steam.

Look up `Children of Orc.'

The player can give assignments to the other Orcs, and the action plans for those assignments are displayed in-game. The Orcs are smart enough to find cheap plans. When tasked with procuring stone, e.g. they will see what the quickest way is. Sometimes scavenging for discarded stone may be cheaper, other times, with pickaxe in hand near a quarry, quarrying is the way to go of course. They adapt. But whatever plan they come up with, it is communicated to the player in an info-window.
