  • All junior devs should read OCs comment and really think about this.

    The issue is whether is_number() is performing a semantic language matter or checking whether the text input can be converted by the program to a number type.

    The former case - the semantic language test - is useful for chat based interactions, analysis of text (and ancient text - I love the cuneiform btw) and similar. In this mode, some applications don't even have to be able to convert the text into eg binary (a 'gazillion' of something is quantifying it, but vaguely)

    The latter case (validating input) is useful where the input is controlled and users are supposed to enter numbers using a limited part of a standard keyboard. Clay tablets and triangular sticks are strictly excluded from this interface.

    Another example might be is_address(). Which of these are addresses? '10 Downing Street, London', '193.168.1.1', 'Gettysberg', 'Sir/Madam'.

    To me this highlights that code is a lot less reusable between different projects/apps than it at first appears.

  • Couldn't agree more.

    And now that this occurred, and cost $500m, perhaps finally some enterprise companies may actually resource IT departments better and allow them to do their work. But who am I kidding, that's never going to happen if it hits bonuses and dividends :(

  • It is terribly sad - they must live in a world of hurt.

    However so many of these people actively try to hurt LGBTQ+ and trans people by inciting hate and changing laws to harm the non-straight. In particular they have been preaching that being gay/trans equates to being a child molester. This is horrific and needs to stop. Exposing the hypocrisy is essential to reducing the harm they are inflicting to real people right now

  • The first GPT-4-class AI model anyone can download has arrived: Llama 405B

    Jump

  • Typically you need about 1GB graphics RAM for each billion parameters (i.e. one byte per parameter). This is a 405B parameter model. Ouch.

    Edit: you can try quantizing it. This reduces the amount of memory required per parameter to 4 bits, 2 bits or even 1 bit. As you reduce the size, the performance of the model can suffer. So in the extreme case you might be able to run this in under 64GB of graphics RAM.

  • I think that's a better plan than physically printing keys. I'd also want to save the keys in another format somewhere - perhaps using a small script to export them into a safe store in the cloud or a box I control somewhere

  • An angry admin shares the CrowdStrike outage experience

    Jump

  • You need at least two copies in two different places - places that will not burn down/explode/flood/collapse/be locked down by the police at the same time.

    An enterprise is going to be commissioning new computers or reformatting existing ones at least once per day. This means the bitlocker key list would need printouts at least every day in two places.

    Given the above, it's easy to see that this process will fail from time to time, in ways like accicentally leaking a document with all these keys.

  • What about the people who lived in the Americas or the Pacific 1800 years ago? These people could not have heard of Jesus as missionaries could not have spread any word to them at this time.

    (And while I'm about it, Christianity was a whole different thing back then - the Trinity hadn't been invented, there were multiple sects with very different ideas, what books would be in the New Testament had not been decided, etc etc. People with beliefs of that time would seem highly unorthodox today, and the Christianity of today would be seen as heretical by those in the 3rd century, so who's going to heaven again?)

    Purgatory was invented for the purpose of not sending good people who had not heard of Jesus to hell. But still, these people were denied their chance to get to heaven which seems mighty unfair.

  • Were zx spectrum +2 keyboards disgusting to type on?

    Jump

  • I had a Sinclair QL which pioneered the keyboard. It wasn't great - it was far behind the Acorn BBCs and the Commodores) but it was quite usable.

    There was significant vertical travel, and there was variation in the push the key gave back - increasing to a point of no return, then a quick downward movement to the thunk of the end of key travel.

    I could type moderately fast on it.

  • Vaccines don’t cause autism, but the lie won’t die. In fact, it’s getting worse.

    Jump

  • That was one of the original proposed mechanisms to explain how the (obviously false) autism was caused.

    But since then, since thiomersal was removed, other 'causes' and moral issues have been invented, including cells from abortions.

    The one that makes me laugh the most is that it's terrible that the poor poor baby is exposed to so many illnesses (measles, mumps, rubella, polio, tetanus, notovirus, rotovirus and more) in such a short space of time, it's no wonder the poor dear's immune system is compromised. And then the same mother drops the kid off at daycare and exposes the poor dear to all those viruses and more - and live viruses at that.

    There is no bleeding logic, just feels. And they get so angry at the fake harm that medicine is causing, and simultaneously actually causing real harms to real people.

  • Switching to OCaml bois

    Jump

  • I don't think that the anti-oop collective is attacking polymorphism or overloading - both are important in functional programming. And let's add encapsulation and implementation hiding to this list.

    The argument is that OOP makes the wrong abstractions. Inheritance (as OOP models it) is quite rare on business entities. The other major example cited is that an algorithm written in the OOP style ends up distributing its code across the different classes, and therefore

    1. It is difficult to understand: the developer has to open two, three or more different classes to view the whole algorithm
    2. It is inefficient: because the algorithm is distributed over many classes and instances, as the algorithm runs, there are a lot of unnecessary calls (eg one method on one instance has to iterate over many instances of its children, and each child has to iterate over its children) and data has to pass through these function calls.

    Instead of this, the functional programmer says, you should write the algorithm as a function (or several functions) in one place, so it's the function that walks the object structure. The navigation is done using tools like apply or map rather than a loop in a method on the parent instance.

    A key insight in this approach is that the way an algorithm walks the data structure is the responsibility of the algorithm rather than a responsibility that is shared across many classes and subclasses.

    In general, I think this is a valid point - when you are writing algorithms over the whole dataset. OOP does have some counterpoints encapsulating behaviour on just that object for example validating the object's private members, or data processing for that object and its immediate children or peers.

  • What is the oldest common food in the typical western diet?

    Jump

  • I'm going to suggest food items that we still take from nature and eat with minimal preparation:

    • Honey
    • Fish like salmon, trout, grouper
    • Shellfish (eg oysters)

    We have evidence of shellfish and fish being eaten for a very long time - at least the middle stone age at 140kya - in middens which are 10s of thousands of years old.

    Honey is likely to have been a food source - a treat even - even before humans left Africa (so before 100kya) but sadly this would be invisible in the archeological record

    Jargon is the mind-killer.

    Jargon is the little-death that brings total confusion. I will face the jargon. I will permit it to pass over me and through me. And when it has gone past I will turn the inner eye to see its path. Where the jargon has gone there will be clarity. Only sense will remain.
