Combined with a replication strategy and automated health checks, a load balancer could direct traffic to a healthy instance automatically.

I recently purchased Computer Systems: A Programmer's Perspective [0] and am currently working through it with pen and paper.

I've only had peripheral exposure to writing in assembly and "systems level" programming so I'm really quite enjoying it.

Not mentioned in my initial comment, but yeah, I'm viscerally aware of the affect the time period and resources at the time have on API design in C and other languages from that time period.

The null pointer in place of the operand here just seemed like a really good quirk to point out

Besides my DA/Algo classes in College, I've never used C seriously. And you know, it's semantics like this that really make me go WTF lol....

From strtok man page... "The first time that strtok() is called, str should be specified; subsequent calls, wishing to obtain further tokens from the same string, should pass a null pointer instead."

Really?? a null pointer.. This is valid code:

  char str[] = "C is fucking weird, ok? I said it, sue me.";
  char *result = strtok(str, ",");
  char *res = strtok(NULL, ",");

Something very similar to this was pulled of by Ukraine last year

Wow... A speculative branch prediction path actually get's preemptively executed despite the branch outcome? No matter if the execution has side-affects??? That's quite amazing. Are modern CPUs doing speculative execution like this and just put extra safeguards around affects or do they just prefetch / decode instructions now-a-days?

Is this macro mapped in vim or OS level? Sounds interesting.

Congrats on shipping!

Two things, does anyone else feel like 2017 was not 9 years ago and rather feels like it was just yesterday? I use a 2017 iMac running MacOS 13.7.8. It appears my hardware will not support any newer version of MacOS. For the most part, I haven't been too discouraged by this as I prefer older MacOS designs over the newer ones.

However, this is the second time in 2 days I've actually hit a wall in the Apple eco-system due to an older OS.

Last night I tried to build Ghostty to hack on a feature... it needs Xcode SDK 26 which isn't supported on Xcode 14 (latest version I'm able to install).

Now today, attempting to try this app out, I can't launch it due to being on too old of an OS.

It's really a shame because this iMac from 2017 is quite the capable machine. Absolutely no reason to upgrade it (from a hardware / performance standpoint).

"No client simulation allowed only server."

Seriously

Who knows if this is the reason that Trump is putting in place this trade war and increasing tariffs, but this paper is a very interesting perspective on why someone in the position the US is in, in regards to the global economy is extremely thought provoking [1].

Seeing as how Trump appointed the author into his political circle though could be evidence this is the ultimate goal.

The paper is quite lengthy, however, in the beginning Stephen explains this idea of the Triffin Dilemma. A country that acts as the worlds reserve currency and thus creates enormous demand for their currency for things outside of goods are at a disadvantage that exasperate their trade deficit. This is implicit for a countries currency where most global trade is settled in their dollars, not to mention the benefits of holding the world reserve currency as a value store or investment.

I've wondered since the tarifs were announced how much impact they can actually have, but besides that point what is a reserve currency country to do? Give up their reserve currency status? There are significant downsides to that as well...

Well isn't that the whole point? At a fundamental level, investment profits are a payment for the risk you take. No risk equals no profit. There are "safe" investments currently. You can get paid 4% a year roughly to hold treasuries right now. Considered a "risk free" investment (Which sure, maybe the merits can be argued).

But at the end of the day the only way to profit from an investment is taking some risk. It all comes down to pricing that risk.

Does this mean it's impossible in Zig to do strictly Stack related recursion and just by the mere inclusion of a recursive function your implicitly getting heap allocations alongside?

What is the value proposition for these form libraries? Is it scale? Is it the custom builder? How complex are people's HTML forms these days from a UX perspective?

I was browsing the code, and noticed this forms library was using Supabase, presumably a paid service if this OSS library takes off. I just can't seem to grasp why a custom form building library needs a 3rd party, managed Database included. Scale maybe?

These are genuine questions as I'm woefully unaware of the state of HTML forms / Frontend in 2025

Super interesting project! I have zero experience writing Postgres extensions, but I was browsing a blog post about an extension the other day. I was curious what ones workflow looked like while developing a PG extension. From the little I read, it looked like you would have to recompile postgres, including your extension, then enable it just to run it. Seems like a very long feedback loop. Was I missing something?

Is there a DBMS or storage engine intended for a DBMS that does bypass the filesystem altogether? I'm not aware of any, but at the same time I don't have a full grasp of all the storage engines offered.

It almost seems like a ridiculous idea to me for a database component author to want to write there own filesystem instead of improving their DB feature set. I hear the gripes in this thread about filesystems, but they almost sound service level user issues, not deeper technical issues. What I mean by that, is the I/O strategies I've seen from the few open source storage engines i've looked at don't at all seem hindered by the filesystem abstractions that are currently offered. I don't know what a DBMS has to gain from different filesystem abstractions.

Scrolling behavior is one of my biggest gripes with tmux. I've not done enough digging on terminal emulators and multiplexers to know why this is.

Is this an inherent limitation of multiplexers or does it stem from a choice made by tmux?

I have been wrestling with having to enter scroll mode for so long now. It's so infuriating. It works without configurations on iTerm, but does not work on a single other terminal emulator I've tried.

I just tried your config setting in Ghostty and still, when I use my mouse it scrolls through zsh history, not the screen

Being an advanced scuba diver is absolutely no indication of one’s ability to freedive. You Absolutly can not compare the two besides both taking place underwater.

On top of that, even if this guide was a Divemaster which is far from guaranteed given the other safety failings from this company, being an advanced Divemaster does not equate to one’s ability to cave dive. Survivors state the lack of lighting in the boat and so I’m assuming he would have had to navigate the boat in complete dark under water. So while not exactly cave diving, it’s equatable. An activity that’s insanely dangerous to anyone, even Divemasters that don’t have cavern or cave experience.

There’s a reason there’s a grim reaper sign at the entrance of caves in popular dive locations.

This is exactly what us hunters do year after year, time and time again. Drive for hours, hike for miles. Gathering what information we can. Then at some point we have to make assumptions and commit to some scenario in hopes it pans out the way you assume.

A tremendous amount of time and effort is spent with it all riding on a few, hopefully, well placed assumptions. Sometimes it works out, sometimes it doesn't. Usually your acquaintances only hear about the times the hunt works out. Same with this. We only hear about it, because it worked out for the hunter

There's also a great story that speaks more towards the detriment of using Black-Scholes as an investment thesis.

I'm not familiar with rails, so sorry if your reply above inherently answered this.. So you're enabling the tracing with a call in your controller method, but how is the tool capturing function params and returned values for sub-calls in the respective controller method?

Is it waiting for execution to return to the controller method and polling the stack trace from there?

I'd be interested in talking with you about this

Recently found myself in the same business. Early similar to you. Small business', strictly local.

I've got a couple high level questions for someone more seasoned than I.

Could I email you?

That's awesome! Really cool to see another knowledgeable fan of Muay Thai on this forum!

Totally unrelated, but what's the connection between your name and the famous Muay Thai fighter Yodthanong Photirat, better known as Yodsanklai Fairtex?? [1]

We have to assume this is partly the reason for the parabolic increase in TSLA stock price don't we? Thinking out loud here, correct me if I'm wrong anywhere..

According to your second source, there was $14.5B worth of shorted shares on 1/14/2020 and the closing price for $TSLA on that day was $107.58.

According to the source below [1], as of 11/15/2020 there was $27.19B worth of short shares. Closing price 11/16 was $408.09

Shares shorted 1/14/2020: 14.5B / 107.58 = 134.78 Million Shares

Shares shorted 11/16/2020: 27.19B / 408.09 = 66.62 Million Shares

According to TSLA July 2020 10Q they had 186M shares outstanding [2] so while not the most accurate when comparing a 9 month change in Shorted shares, we can estimate in the neighborhood of 1/3rd the shares on the market were covered by short sellers.

This is awesome man, truly happy for ya.

Your comment isn't the first time I have heard this advice, "Find a small non tech company and get involved" however I have previously written this advice off for w/e reason.

I now find myself in search of a new opportunity and am very much like many other commenters in this thread, highly unsatisfied with "rat race" type jobs, and if I'm not happy I don't perform up to my ability well.

I'm actually very interested in exploring your path, possibility finding a small non tech company and seeing where/ if I could add value to their organization with my software development experience.

All my previous jobs have been found via standard software development job boards though, StackOverflow, LinkedIn, homegrown software job boards, etc. Do you have any advice on finding a small non tech company that might be looking to add a software developer to their ranks?

Honestly I'd love to chat with ya personally. If you're comfortable shoot me an email otherwise any incite here would be wonderful. Email in my Bio

"repo markets don't help corporate debt at all"

I'm not sure I agree with this statement. The repo market may not help or hinder corp debt directly, but I think it very much so effects corporate debt.

Corporations presumably get their loans from banks. What facilitates banks to make these loans? The Repo market. What happens if the repo market collapses / shrinks / endures instability? Banks most likely, would not be able to make as many loans and the rate for future loans would increase due to lower supply and higher demand.

On top of future loans, this could have a negative impact to current outstanding loans held by corps. I'm not 100% sure the terms of corporate loans, but if they have variable rate loans with banks, this shrinking of loan supply coupled with increased demand for liquidity would surely hurt some of these corporations.

I look at it this way. Your essentially buying a companies future earnings by buying their stock. For some time here, corporate earnings are going to take a hit. B2C probably the hardest, but B2B will also feel the effects, ripple effect if you will. The strain these quarantines are putting on Small business owners will also ripple into the larger corporate companies that the market is composed off because these SBO are the consumers too.

I don't have a full understanding of the Repo market, but I do get it at a moderate level. I understand that it acts as the "lube" to our financial system and It's obvious it's not functioning correctly. What effect will this happen on the growing corporate debt that's out there? What effect will the lower revenues have on the ability for business' to pay back the debt and interest?

These are questions I have, but don't necessarily have factual answers for. However I don't feel good about the answers to them and for that reason do think were in for a recession.

Based on your opinion, you think productivity will slow and inflation will rise (regardless of cause) that is the definition of stagflation and by definition bad for the economy, bad for equities. Given these two things, higher inflation lower productivity, we would expect to see the price of equities go lower.

Also side note which is interesting, but not entirely sure how it effects things.
