«Surely the point of writing readable code is to make it easy to come back later and modify it... But if you adhere so strongly to readability that you reject any attempts to improve the code out of fear they will increase its complexity, then you've destroyed the benefits of that readability. It's kind of the opposite of technical debt - you've spent a lot of effort building up technical credit by keeping the code readable, but that effort is wasted unless you eventually spend the credit on valuable features or performance. Obviously there's a danger of spending too much and going back into debt, but you shouldn't ignore the danger of spending too little.» #programming #quote #link https://lwn.net/Articles/754782/

It's an interesting take. One obvious thing that the author of the quotation omits is the ability to reason about the code when something goes wrong in production. ‎· 9000

«At my workplace, we use my #database library [beam](https://github.com/tathougies/beam) to make sure that our queries (written in a Haskell-like DSL) are runnable on the backends we choose. ... We freely join against queries (which may themselves be the results of joins, aggregates, window functions, etc). The SQL produced is what you'd expect.» @squadette, I think you thought along these lines in one of your posts.

As far as I can tell, they map physical table to a “class”. My idea is to map attributes of a class to fields in tables. ‎· псы в рапиде
Comment
What I liked is the idea of abstracting tables and datasets, and freely doing joins on them, which then get translated to whatever the DB layer supports. That a class, in your model, is decoupled from tables, and is represented as a query behind the scenes, but you still do normal relational things between your models. ‎· 9000

The less cool part: this is done via reference counting, not via advanced lifetime / escape analysis as one could have hoped. Ephemeral data in Clean are based on the latter. I wonder if a refcount-based C++ variant exists. ‎· 9000

And more about the #madness of inflicting good on people, whether they want it or not: «[P]ress publishers will receive—whether they like it or not—an “inalienable right to obtain an [sic] fair and proportionate remuneration for such uses.” This means that publishers will be required to demand payment from news aggregators. This inalienable right directly conflicts with publishers who wish to share freely and openly using Creative Commons licenses.» (https://medium.com/the-mission/the-tragedy-of-fritz-haber-the...) #link #copyright

Что-то никто почти не понял, поэтому не ночью и по-русски. в ЕС внесли законопроект, по которому _запрещается_ бесплатно раздавать свои произведения. Лицензии типа Creative Commons он делает юридически ничтожными: от права на вознаграждение нельзя отказаться. Если вы любите картинки в википедии, например, то показ их на территории ЕС станет стрёмным делом. Не говоря уж о разных блогах и даже целых газетах. ‎· 9000

А что в этом контексте считается произведением? Например, человек сочиняет истории и выкладывает их в общедоступный блог, откуда другие могут их скопировать - ему запретят? ("Тебя посодють, а ты не пиши"?) ‎· angry cat swimming in floodwater

The idea touched but not explicitly formulated in [1]: Being creative in adult age is a rare gift, but not because being born creative is rare. The rare gift is to pass through the education / indoctrination mechanisms of the society ("do it because I tell you so"), adapt to them, but still preserve (some of) the creativity.

I love this kind of "pattern matching", when a "smart and complex" thing is looked at attentively, and mapped to well-known, simple, pretty standard things, because it consisted of these things from the very beginning. They were just not recognized. Here monadic parsing is mapped to StateT and applicatives, and things become simple and nearly trivial: http://vaibhavsagar.com/blog/2018/02/04/revisiting-monadic-pa... #functional #programming #beauty #link

По знаменитой гипотезе из Blindsight, человеческий разум — проблема и паразит вида-носителя, перетягивающий ресурсное одеяло целиком на себя, в свои бесконечные глубины рассуждения, оторванные от практики выживания вида. Венкатеш Рао внезапно поёт романтический гимн ровно этому свойству разума, типа «The life of the mind, as experienced by those who enjoy living it, is about the whys of the human condition, rather than the hows. That thinking can be a means to valuable ends is almost the least interesting thing about it.» И дальше, по заветам Deus Ex, мечтает о взаимо-желанном слиянии человека и машины. https://mailchi.mp/ribbonfarm/intellectualism-in-a-digital-mi... #link

Любопытно попроверять на практике такой вывод: «When I talk to strident anti-intellectuals, beneath the surface animus, I often detect an undercurrent of real fear. I can tell they know monsters lurk where they dare not dive. They are not bad at thinking (many are much better at it than I am), they're afraid of where thinking might take them.» Мне кажется, что тут есть некоторая недооценка человеческой лени и просто другой области интересов.

These guys just launched a rocket to LEO: https://www.theverge.com/2018/1/21/16915996/ Not a big deal, one could say in 2018, but this is their first commercial launch, and the second launch total. Mr. Musk should pay attention to these shrewd businessmen. #space #link

They do small rockets with a small payload (300 to 500 lb) and already have a bunch of orders to the upcoming launches. I can imagine them saying: "Building a small orbital rocket is not rocket science anymore; let's just execute it well and start raking in our millions already". ‎· 9000

Since #netneutrality is a hot topic again, I'd like to remind us the best solution I've ever encountered, from 3 years ago. «I'd call up the ISPs and say this: "Hello, Uncle Sam here. You can charge whatever you like based on the contents of what you are carrying, but you are responsible for that content if it is hurtful; inspecting brings with it a responsibility for what you learn. -or- You can enjoy common carrier protections at all times, but you can neither inspect nor act on the contents of what you are carrying and can only charge for carriage itself. Bits are bits. Choose wisely. No refunds or exchanges at this window."» Source: http://geer.tinho.net/geer.blackhat.6viii14.txt #link #quote

The keynote is actually a treasure trove on various topics. E.g. «Privacy used to be proportional to that which it is impossible to observe or that which can be observed but not identified. No more -- what is today observable and identifiable kills both privacy as impossible-to-observe and privacy as impossible-to-identify, so what might be an alternative? If you are an optimist or an apparatchik, then your answer will tend toward rules of data procedure administered by a government you trust or control. If you are a pessimist or a hacker/maker, then your answer will tend towards the operational, and your definition of a state of privacy will be my definition: the effective capacity to misrepresent yourself.» ‎· 9000
