linuxrebe1··on Ask HN: Could early 80s computers have had better software given today's CS?
I would agree, I would also add that generally programmers today are not used to dealing with the memory limits of '80s computers. What is now considered an embedded device, back then was a desktop. My smartwatch likely has more memory than a PC Jr.
linuxrebe1··on The anatomy of a 2AM mental breakdown
Based on the way you were troubleshooting it. You can tell you're a programmer first. You went to your code, you went to your logs. Both reasonable, both potential causes of the problem. Both ignore the primary clue that you had. It worked on localhost.

As an SRE/devops/platform engineer or whatever the title of the day is people want to give. I would have zeroed in on the difference between the working system. And the non-working system. Either adding and then removing, or removing and then adding back the differences one at a time. Until something worked. What I see is two things. 1) you have an environment where it does work. 2) the failing environment was working, then started failing.

Is my method superior to yours, no. It just is being stated to highlight the difference in the way we look at a problem. Both of a zero in on what we know. I know systems, you know code.

linuxrebe1··on No more boot loader: Please use the kernel instead
I'm curious if they're proposal will be capable of handling multi-os boots. I know grub can, I can have Linux and windows and possibly even a third OS if I want. I am concerned that red hats solution the well-intended, may be rather myopic, and be commercial only. What I failed to understand, is what problem this solves for systems that I probably only reboot once or twice a year. (Given that it only works with Linux only systems)
linuxrebe1··on The Curse of Docker
99.9% of the problems you spoke to, which are very real. Could be solved if people building the software would just understand one thing. A container is not a mini VM. It is not in any way shape or form a virtual machine. If what you need is a lightweight virtual machine. Build that. Do not build a container because it's the latest and greatest buzzword. But instead I see large monolithic applications, shoved into a container, and then I hear a multitude of complaints about performance issues ETC. You may be able to drive a nail with a screwdriver but it's not a good idea.
linuxrebe1··on A C Compiler that fits in the 512 byte boot sector of an x86 machine
This is scary. It hides in boot sector and can compile tiny C apps to bootstrap malware. Wipe system, rebuild, blackhat is soon back in, rinse and repeat. Th end solution ... destroy the box.
linuxrebe1··on Ask HN: What are you passionate about at the moment?
AI induced reactive Observability. What if we could (ok we can just haven't) create a system that based on past solutions looks for a specific condition and then, when that condition is met, takes specific actions immediately and then reports to the human rather than reporting to the human and waiting for them to take a known set of actions. Beyond just "container died restart" but getting into "Container 2 is exhibiting performance that indicates it is suffering a very slow memory leak. Capture logs and readings to prove this, restart the container and report findings to a human"
linuxrebe1··on Why even let users set their own passwords?
I'll ask, in the corporate world. Why even allow them to know their password. To login to their device a Yubi Key or Door key could be used (or similar) then once logged into their laptop they have an app the works like 1password or lastpass that inserts their passwords, updates their passowrds etc. for everything the company uses. (If they have a reddit account that is non corporate they could use their own pw manager.) This would also solve the "shared password" issue where a company that has a corporate Twitter account, they control access to the credentials and the credentials. Also gives you a paper trail in that you now know who used the credentials at the time of a post.
linuxrebe1··on If-then-else had to be invented
Short would be, 'and' implies, coincidence, not causality. 'Or' implies choice. If-then implies causality ("If my pants are dirty, then they need to be cleaned")

The big difference I see is with 'OR' in programing the options are exclusive. Ex: "Are you tired or hungry" The answer is yes if you are tired. Yes if you are hungry, Yes if you are both. No if you are neither. This is natural English. In programming if you are both. The answer is No.(False)
