xaedes··on Common tech jobs described as cabals of Mesoamerican wizards
If you like that you might also like The Wizardry series by Rick Cook

Here a short description from some bookseller for the first book "The Wiz Biz":

It all began when the wizards of the White League were under attack by their opponents of the Black League and one of their most powerful members cast a spell to bring forth a mighty wizard to aid their cause. What the spell delivered was master hacker Walter Wiz Zumwalt. The wizard who east the spell was dead and nobody—not the elves, not the dwarves, not even the dragons—could figure out what the shanghaied computer nerd was good for. But spells are a lot like computer programs, and, in spite of the Wiz's unprepossessing appearance, he was going to defeat the all-powerful Black League, win the love of a beautiful red-haired witch, and prove that when it comes to spells and sorcery, nobody but nobody can beat a Silicon Valley computer geek!

For me it will always be "cutie". It is feels better to use as noun but is still somehow cute.
xaedes··on Never mind outrunning a T. rex – you could probably outwalk it
You could outwalk it if does not run, because this here was about walking speed.

---

As for T. rex's next steps, the study authors want to incorporate their flexible tail into models of a running T. rex, van Bijlert said. Maximum running speed for a T. rex is thought to be in the range of 10 to 25 mph (16 to 40 km/h), according to Hutchinson. Biomechanics researchers have long proposed that T. rex's maximum running speed would be limited by the strength of its bones, because the animal was so heavy. However, a flexible tail could change that by acting as a shock damper during running, "allowing it to run faster without breaking its bones," van Bijlert said.

xaedes··on Experiments indicate that bees have surprisingly rich inner worlds
Telling the bees is a tradition in many European countries in which bees would be told of important events in their keeper's lives such as births, marriages and departures and returns in the household. If the custom was omitted or forgotten and the bees were not "put into mourning" then it was believed a penalty would be paid, such as the bees leaving their hive, stopping the production of honey or dying.

Comparing things that are equivalent is pretty pointless, because the outcome would always be the same: "they are the same". We compare things that may be similar but actually different. Comparing things highlights differences and commonalities.

xaedes··on Climate protection: CO2 turned into methanol
The Fischer–Tropsch processes - they are talking about that , don't they, at least very similar - for converting CO or CO2 and methan into liquid fuel seem so attractive... They are feeding on both of the worst green house gases to make fuel. Basically that makes it the reverse process to our climate-sins of burning fossil fuels like there is no tomorrow.

If we could use the Fischer-Tropsch processes to process atmospheric CO2 and methan on a really large scale we could recycle burnt fuel and create a global equilibrium. Fuel would then be used as energy storage instead of energy source. Fuel is an attractive energy storage, because it is simple, has high energy density and we have LOTS of experience and legacy hardware powered by fuel.

From the view point of a simearth/civilization/4x/colonization/strategy game player that is a technology I would like to unlock.

Obviously simplistic view, because it is not that easy... Like the article states: "However, they have the major disadvantage that they are not robust. If there are certain other substances in the exhaust gas stream besides carbon dioxide, for example sulfur, the catalyst quickly loses its activity. It is said that the catalyst is poisoned."

Good to see them make progress in that area!

xaedes··on GitHub Copilot is generally available
As they don't mention it I doubt it.

Tabnine, a similar competitor, explicitly mentions this on their website:

" Tabnine only uses open-source code with permissive licenses for our Public Code trained AI model (MIT, Apache 2.0, BSD-2-Clause, BSD-3-Clause). "

Other commenters here say the completion quality is worse than Copilot. I use Tabnine for local short completions only and am quite happy with it. Didn't try Copilot yet.

xaedes··on How to Not Get Hit by Cars
My misunderstanding, I misread part of your comment and was thinking you meant using the sideway as a car driver for some reason.

I am a bicylce rider, that wants to survive. I dont drive by car. Some car drivers are reckless and the cars they command are pretty dangerous. That makes me avoid car lanes.

My prefered solution is separate bike lines - separate from cars, separate from pedastrians. To avoid #1 problem listed on the page I prefer crossings that are ultimately regulated by traffic lights, i.e. no free right turn when light is red. Otherwise the safest spot to cross a street is on official crossings, best is with traffic lights, where you have enough distance to road turns or intersections. So that car drivers have a lot of time to see you crossing the street and you can see cars coming on both lanes when checking in both directions. When it is too close to a turn, a car can appear from around the corner without you being able to see each other first. A bit like the "right cross" and "crosswalk slam" issue from the website. Almost all the other issues are related to driving on the car lanes, hence the call for separate bike lanes.

I know it is not applicable everywhere - what can you do when there are no bike lanes... Fortunately in my home town we have enough space allocated for those and lots of traffic lights.

xaedes··on How to Not Get Hit by Cars
That is why I suggested:

> Avoid crossing street at intersections that are not ultimately regulated by traffic lights. Instead try to find a crossing, preferable with traffic lights, on a street with enough distance to intersections where cars could suddenly appear from.

And a car driving on sidewalk should be super focused. I mean the car does not belong there at all!

xaedes··on How to Not Get Hit by Cars
How to avoid all of these: Have and use bike lanes that are isolated from car lanes, e.g. on sidewalks.

Avoid crossing street at intersections that are not ultimately regulated by traffic lights. Instead try to find a crossing, preferable with traffic lights, on a street with enough distance to intersections where cars could suddenly appear from.

Instead one is often instructed to ride right next between/to cars in the middle of the lane. In the name of safety! Shaking my head... Would you let your child rather ride its bike between those metal monsters or in actual safety? Some countries have exceptions for children, that allow them to ride on sidewalk, even when adults are required to ride on car line. Why is that? Maybe because it is safer for the children. Well then it should apply in general regardless of age. Cars are dangerous.

xaedes··on The computers are fast, but you don't know it
> I think developer speed is more important than optimising clock cycles unnecessarily.

Developer time is spent once. Users will always have to pay the price of additional run time. For. Each. Single. User. Always.

It scales!

Due to the scale of, e.g. slow front-ends, with millions of users, this takes a HUGE amount of time. Only to save a few hours or days to develop it better.

Having 1 million users each wait a single second is already 11 days. If they have to wait that single second for each interaction, it quickly adds up.

It is also bad for the environment due to scaled up inefficiency and resulting increase of power usage.

xaedes··on Ask HN: Best place to publish a Haiku, accessible 10k years from now?
Very enlightening, this is a perspective on oral vs. written communication I never considered.
xaedes··on Ask HN: Best place to publish a Haiku, accessible 10k years from now?
Without jokes, build a successful religion with the haiku in focus. But it probably won't survive in its exact form over this time. Lots of physical artifacts with the haiku engraved distributed over the world should provide error correction. You also need to keep the language of the haiku intact. Provide a superb language specification like Pāṇini did for Sanskrit. Making it a sacred language like Arabic in Islam seems to add some kind of longevity.

Or piggy-back on some similar endeavour and inject your haiku.

xaedes··on Ten things all languages have in common
They claim "All languages can communicate all ideas and feelings", but I think it is wrong. First of all there are ideas and especially feelings which can not be directly communicated with language at all. Surely you can label them and hope for the best, that the other side can relate to it, but you can not actually transmit the true idea or feeling you have. If language could truly communicate all ideas it should also be able to communicate all tacit knowledge, i.e. the term for the concept of "tacit knowledge" wouldnt be necessary to begin with. You can try to explain, but the explanation is only the map, not the territory.

Or to relate it with computing terminology:

Language is digital but existence is analog.

xaedes··on Greece passes first climate law, vows to cut dependence on fossil fuels
> Greece is bankrupt

From 4 Apr 2022:

Greece has received three international bailouts from the euro zone and the IMF worth 280 billion euros ($307.19 billion) since 2010. It emerged from its latest bailout in 2018 and has relied on the debt markets to cover its borrowing needs since.

“Greece concluded today the repayment of its debts to the IMF,” Finance Minister Christos Staikouras said in a statement. After previous early repayments to the IMF, Greece owed 1.9 billion euros in loans due by 2024, the last batch of a total of 28 billion euros the Fund provided between 2010 and 2014.

xaedes··on Why Japan's rail workers can't stop pointing at things (2017)
This is a great technique to enhance focus and spot details. After I read about it the first time I thought that must also work for other things. Since then, during particularly hard sessions of of debugging or (code) reading, I use it to physically point at code/text. Sometimes with both hands. It forces me to actually pay attention to the thing I point at. In this way it also helps spotting tokens that would otherwise be skipped, like the double "of" in the third sentence of this comment. Physically following some data, control or logic flow by tracing it out can also help to avoid losing the proverbial "thread".
xaedes··on Bunnymark GL in Jai – 200k sprites at 200fps [video]
Nice demo! We need more of this approach.

You really can achieve amazing stuff with just plain e.g. OpenGL optimized for your rendering needs. With todays GPU acceleration capabilities we could have town-building games with huge map resolutions and millions of entities. Instead its mostly only used to make fancy graphics.

Actually I am currently trying to build something like that [1]. A big big world with hundreds of millions of sprites is achievable and runs smoothly, video RAM is the limit. Admittedly it is not optimized to display those hundreds of millions of sprites all at once, maybe just a few millions. Would be a bit too chaotic for a game anyway I guess.

xaedes··on A Swedish skier was basically frozen, but lived (2016)
Specifically I was referring to the Parsis and their Zoroastrian teachings. The introduction to the quoted book has put it in those words:

https://www.sacred-texts.com/zor/sbe04/sbe0402.htm#page_xi

The Zend-Avesta is the sacred book of the Parsis, that is to say, of the few remaining followers of that religion which feigned over Persia at the time when the second successor of Mohammed overthrew the Sassanian dynasty [At the battle of Nihâvand (642 A.C.)], and which has been called Dualism, or Mazdeism, or Magism, or Zoroastrianism, or Fire-worship, according as its main tenet, or its supreme God [Ahura Mazda], or its priests, or its supposed founder, or its apparent object of worship has been most kept in view.

> Indeed, they are not the Stargate ancients. But in the same book they write about some other kind of "golden ring" with a most interesting coldness related story:

https://www.sacred-texts.com/zor/sbe04/sbe0408.htm

7 (17) 2. Then I, Ahura Mazda, brought two implements unto him: a golden ring and a poniard inlaid with gold. Behold, here Yima bears the royal sway!

8 (20). Thus, under the sway of Yima, three hundred winters passed away, and the earth was replenished with flocks and herds, with men and dogs and birds and with red blazing fires, and there was no more room for flocks, herds, and men.

9. Then I warned the fair Yima, saying: 'O fair Yima, son of Vîvanghat, the earth has become full of flocks and herds, of men and dogs and birds and of red blazing fires, and there is no more room for flocks, herds, and men.'

10. Then Yima stepped forward, towards the luminous space, southwards, to meet the sun, and (afterwards) he pressed the earth with the golden ring, and bored it with the poniard, speaking thus:

'O Spenta Ârmaiti, kindly open asunder and stretch thyself afar, to bear flocks and herds and men.'

11. And Yima made the earth grow larger by one-third than it was before, and there came flocks and herds and men, at his will and wish, as many as he wished.

12 (23). Thus, under the sway of Yima, six hundred winters passed away, and the earth was replenished with flocks and herds, with men and dogs and birds and with red blazing fires, and there was no more room for flocks, herds, and men.

> this process of using the golden ring is used multiple times, with a total of 1800 winters passing

> but it is not over:

22 (46). And Ahura Mazda spake unto Yima, saying:

'O fair Yima, son of Vîvanghat! Upon the material world the fatal winters are going to fall, that shall bring the fierce, foul frost; upon the material world the fatal winters are going to fall, that shall make snow-flakes fall thick, even an aredvî deep on the highest tops of mountains.

23 (52). And all the three sorts of beasts shall perish, those that live in the wilderness, and those that live on the tops of the mountains, and those that live in the bosom of the dale, under the shelter of stables.

24 (57). Before that winter, those fields would bear plenty of grass for cattle: now with floods that stream, with snows that melt, it will seem a happy land in the world, the land wherein footprints even of sheep may still be seen.

25 (61). Therefore make thee a Vara, long as a riding-ground on every side of the square, and thither bring the seeds of sheep and oxen, of men, of dogs, of birds, and of red blazing fires. Therefore make thee a Vara, long as a riding-ground on every side of the square, to be an abode for men; a Vara, long. as a riding-ground on every side of the square, to be a fold for flocks.

26 (65). There thou shalt make waters flow in a bed a hâthra long; there thou shalt settle birds, by the ever-green banks that bear never-failing food. There thou shalt establish dwelling places, consisting of a house with a balcony, a courtyard, and a gallery.

27 (70). Thither thou shalt bring the seeds of men and women, of the greatest, best, and finest kinds on this earth; thither thou shalt bring the seeds of every kind of cattle, of the greatest, best, and finest kinds on this earth.

28 (74). Thither thou shalt bring the seeds of every kind of tree, of the greatest, best, and finest kinds on this earth; thither thou shalt bring the seeds of every kind of fruit, the fullest of food and sweetest of odour. All those seeds shalt thou bring, two of ever), kind, to be kept inexhaustible there, so long as those men shall stay in the Vara.

29 (80). There shall be no humpbacked, none bulged forward there; no impotent, no lunatic; no poverty, no lying; no meanness, no jealousy; no decayed tooth, no leprous to be confined, nor any of the brands wherewith Angra Mainyu stamps the bodies of mortals.

30 (87). In the largest part of the place thou shalt make nine streets, six in the middle part, three in the smallest. To the streets of the largest part thou shalt bring a thousand seeds of men and women; to the streets of the middle part, six hundred; to the streets of the smallest part, three hundred. That Vara thou shalt seal up with the golden ring, and thou shalt make a door, and a window self-shining within.'

> I don't know that that golden ring represents, maybe the sun?

xaedes··on A Swedish skier was basically frozen, but lived (2016)
Sounds like the ancients had similar thoughts as “We will not declare her dead until she is warm and dead.”:

https://www.sacred-texts.com/zor/sbe04/sbe0411.htm

From The Zend Avesta, Part I - FARGARD V.

10 (34). O Maker of the material world, thou Holy One! If the summer is past and the winter has come, what shall the worshippers of Mazda do?

Ahura Mazda answered: 'In every house? in every borough, they shall raise three small houses for the dead.'

11 (37). O Maker of the material world, thou Holy One! How large shall be those houses for the dead?

Ahura Mazda answered: ‘Large enough not to strike the skull, or the feet, or the hands of the man, if he should stand erect, and hold out his feet, and stretch out his hands: such shall be, according to the law, the houses for the dead.

12 (41). ‘And they shall let the lifeless body lie there, for two nights, or for three nights, or a month long, until the birds-begin to fly, the plants to grow, the floods to flow, and the wind to dry up the waters from off the earth.
