   Glad to see this suggested. This is very similar to why OO programming was such a more humane system.

   I have been lazy about this recently. A buddy of mine who works on flash storage told me to do the same with any on disk data structures. This post has pushed me to finally getting checksums in.

   just skimmed the beginning, saw a mention of the use of popcount. That looks interesting. It is an article like this that I really enjoy on HN. Thanks for writing it.

   So - this is interesting. The thing that I always look for is how the system deals with all of the time issues that come up. For example, how does it deal with Daylight Savings, or a leap second, or adjustments to time, or the daemon gettin

   As another commentor noted, this is the way every system is implemented. It is simple, slightly inefficient, and deals with most of the nasty problems that arise when dealing with time on all systems today.

   look at the ARM in the original newton. It had a similar and interesting memory protection unit. The OS was designed to be a single address space.

   This is interesting. For a while, like a few, I thought the solution was to assume the maximum and then iteratively optimize to shorter sequences. I think I even read that in that book on Assemblers and Linkers online. The counter example b

   @SloopJon - I thought the same thing when I looked at this years ago. In fact, many older books/articles mentioned. @rer0tsaz - this is a great counter example. Is there a general form for these types of problems and solutions? Also, I

    SGI computers had value, so people paid $$ for that value that they couldn't get anywhere else. For those people, it wasn't overpriced. Like many companies that do really well, they eventually squandered that edge. To answer you q

    Interesting. I have never heard of Modula-3. I remember Modula-2 and then Oberon. Thanks for sharing.

    OS-9 was a great OS. I ran it on a Coco III with 512k and a hard drive that I got surplus from a DEC guy. I learned C on that system.

    I find TS to be quite productive, especially when combined with a great editor that supports it (Visual Studio Code).

    Is there a description of how react avoids event listeners? How does it observe changes in a model? I've never heard that aspect associated with react before.

    They are very similar, but your answer hits on a good distinction between them. There was a lot of work in Exokernels to allow them to run multiple libOSs on the same hardware safely and securely. Another distinction was that Exokernels did

    I've always wondered... what does a tail call recursion look like in a debugger? Essentially, it is just a loop, but is it worth providing some special indication of tail recursion?

    That first example with 'eq is a little surprising to me. Previous to your post, I believed that Common Lisp symbols were equivalent to Lisp atoms. That is, I just thought of symbols as a way of interning strings (like Smalltalk, Objc,

    I like Apple Pay. I use it every time I can. I can't stand receipts and signing. What I think the reporter isn't covering adequately is why many small merchants are cash only. I suspect they are doing this to avoid taxes. These me

    I know this is not popular. I think ML has a clean syntax and simple but powerful semantics. I enjoyed coding in it. It just looks better than OCaml. Haskell is, I think, even cleaner, but there is a tendency for developers to explore the p

    Unless this has great, zero-issues unix support, I'll have to pass. Is there a laptop like this that is supported by linux or any of the BSDs well?

    very cool - I haven't heard of this before. It looks like it resolves a lot of the issues I have with JSON.

    I agree. Also, given how bad fracking is, this is inferior to solar from an environmental perspective.

    I think they would do just fine for certain roles in a large scale internet service. I don't think you need disks on every node.
