       | I asked an agent to write an http endpoint at the end of the work

       | thought, "maybe it was 20 minutes for 4 hours worth of work". The
       | next day I looked at it and found the logic was convoluted, it
       | tried to write good error handling but didn't succeed. I went
       | back and forth and ultimately wound up recoding a lot of stuff
       | manually. In 5 hours I had it done for real, certainly with a

             | 
             | Or a little while back I was implementing a basic

       | They don't explicitly ask for it, but they won't take you

       | was because it claimed to be "Faster than C++".

       | Watch HN for a while and you'll start to notice that "fast" is
       | the _only_ feature that is necessary to win over mindshare. It is
       | like moths to a flame as soon as something says it is faster than

           | Yes, but under the assumption that it is already built to be
           | as "fast" as possible. "Fast" is assumed. That's why "faster"
           | is such a great marketing trick, as it tunes people into
           | "Hold up. What I'm currently using actually sucks. I'd better
           | reconsider."
           | 
           | "Fast" is deemed important, but it isn't asked for as it is
           | considered inconceivable that you wouldn't always make things
           | "fast". But with that said, keep in mind that the outside
           | user doesn't know what "fast" is until there is something to
           | compare it with. That is how some products can get away with
           | not being "fast" -- until something else comes along to show
           | that it needn't be that way.

             | This is what people are missing. Even those "slow" apps are
             | faster than their alternatives. People demand and seek out
             | "fast", and I think the OP article misses this.
             | 
             | Even the "slow" applications are faster than their
             | alternatives or have an edge in terms of speed for why
             | people use them. In other words, people here say "well wait
             | a second, I see people using slow apps all the time! People
             | don't care about speed!", without realizing that the user
             | has already optimized for speed for their use case. Maybe
             | they use app A which is 50% as fast as app B, but app A is
             | available on their toolbar _right now_ , and to even know
             | that app B exists and to install it and learn how to use it
             | would require numerous hours of ramp up time. If the user
             | was presented with app A and app B side by side, _all
             | things equal_ , they will choose B every time. There's
             | proficiency and familiarity; if B is only 5% faster than A,
             | but switching to B has an upfront cost in days to able to
             | utilize that speed, well that is a hidden speed cost and
             | why the user will choose A until B makes it worth it.
             | 
             | Speed is almost always the universal characteristic people
             | select for, all things equal. Just because something faster
             | exists, and it's niche, and hard to use (not equal for
             | comparison to the common "slow" option people are familiar
             | with), it doesn't mean that people reject speed, they just
             | don't want to spend time learning the new thing, because it

       | Early in my career as a software engineer, I developed a
       | reputation for speeding things up. This was back in the day where
       | algorithm knowledge was just as important as the ability to
       | examine the output of a compiler, every new Intel processor was
       | met with a ton of anticipation, and Carmak and Abrash were
       | rapidly becoming famous.
       | 
       | Anyway, the 22 year old me unexpectedly gets invited to a
       | customer meeting with a large multinational. I go there not
       | knowing what to expect. Turns out, they were not happy with the
       | speed of our product.
       | 
       | Their VP of whatever said, quoting: "every saved second here adds
       | $1M to our yearly profit". I was absolutely floored. Prior to
       | that moment I couldn't even dream of someone placing a dollar
       | amount on speed, and so directly. Now 20+ years later it still
       | counts as one of the top 5 highlights of my career.
       | 
       | P.S. Mentioning as a reaction to the first sentence in the blog
       | post. But the author is correct when she states that this happens
       | rarely.
       | 
       | P.P.S. There was another engineer in the room, who had the nerve
       | to jokingly ask the VP: "so if we make it execute in 0 seconds,
       | does it mean you're going to make an infinite amount of money?".
       | They didn't laugh, although I thought it was quite funny. Hey,
       | Doug! :)

       | browser, I just tried first approach and moved on. It even
       | crossed my mind to add it somehow to Jira marketplace...
       | 
       | Anyway, caches stuff locally and refreshes often. Filtering uses

       | demonstration from 4 years ago, Casey Muratori called out
       | Microsoft's new Windows Terminal for slow performance and people
       | argued that it wasn't possible, practical, or maintainable to
       | make a faster terminal and that his claims of "thousands of
       | frames per second" were hyperbolic, and one person said it would
       | be a "PHD level research project".
       | 
       | In response, Casey spent <1 week making RefTerm, a skeleton
       | proto-terminal with the same constraints Microsoft people had -
       | using Windows APIs for things, using DirectDraw with GPU
       | rendering, handling terminal escape codes, colours, blinking,
       | custom fonts, missing font character fallback, line wrap,
       | scrollback, Unicode and Right-to-Left Arabic combining
       | characters, etc. RefTerm had 10x faster throughput than Windows
       | Terminal and ran at 6-7000 frames per second. It was single-
       | threaded, not profiled, not tuned, no advanced algorithms, no-
       | cheating by sending some data to /dev/null, all it had to speed
       | it up was simple code without tons of abstractions and a Least
       | Recently Used (LRU) glyph cache to avoid re-rendering common
       | characters, written the first way that he thought of. Around that
       | time he did a video series on that YouTube channel about
       | optimization and arguing that even talking about 'optimization'
       | was too hopeful, we should be talking about 'not-pessimization',
       | that most software is not slow because it has unavoidable
       | complexity and abstractions needed to help maintenance, it's slow
       | because it's choked by a big pile of do-nothing code and
       | abstraction layers added for ideological reasons which hurt
       | maintenance as well as performance.

       | and run orders of magnitude faster without adding much complexity

         | the combined two words to be as short as possible.
         | 
         | A naive brute-force solver takes the Cobble wordlist of 64k
         | words and compares every word against every other word and does
         | 64k x 64k = 4Bn loops and in the inner loop body, loops over
         | the combined characters. If the combined words average 10
         | characters long, that's 40 billion operations just for the code

         | for a puzzle that feels like any modern computer should solve
         | it in microseconds.

         | It's always mildly intresting to me how a simple to explain

         | _anything_ in a reasonable time, let alone find fast paths
         | through complex problem patterns. Or perhaps, of all the
         | zillions of possible problems which could exist, find any which

           | I sighed when I read your comment, a comment which is
           | exemplary of what Casey Muratori was ranting against - casual
           | lazy dismissal of the idea that software can be faster, based
           | on misunderstanding and lack of knowledge and/or interest,
           | and throwing out the first objection that comes to mind as if
           | it's an impassable obstacle. There were no bazillion features
           | that made WinTerm slow over the years because Windows
           | Terminal was a new product for Windows 10, released in
           | 2019.[1]. There were piles of problems in Windows Terminal,
           | Casey calls out that it didn't render Right-to-Left Arabic
           | combining glyphs and it wasn't a perfect highly polished
           | program from the outset. And it was an optional download,
           | Fortune 500s wouldn't run it if they didn't want to.
           | 
           | RefTerm was explicitly not a production quality terminal and
           | was _not_ intended to be a replacement for Windows Terminal.
           | RefTerm was a _lower bound_ for performance of an untuned
           | single-thread terminal. RefTerm was a proof of concept that
           | if Microsoft had spent money and engineering skill on
           | performance they could have profiled and used fancy
           | algorithms and shortcuts and reimplemented slow Windows APIs
           | with faster local ones, used threading, and _improved_ on
           | RefTerm 's performance. A proof that "significantly faster
           | terminals are unrealistic" is not true, that all the casual
           | dismissals of why it's impossible are not the reasons for
           | slowness, and that 10x better is an easily achievable floor,
           | not a distant unreachable ceiling.
           | 
           | As a result of Casey's public shaming, Windows Terminal
           | developers _did_ improve performance.
