We really need to revise this to say "there is no global free lunch."

You can and often do get local free lunches.
These are great questions.

All of the above, actually.

Turing-completeness and the uncomputability thereof are widespread, easy to build, hard to keep away, and affects everything that might happen at runtime.

A list of things that can happen is infinite, but that list absolutely includes:

* Whether a particular function pointer resolves to certain functions,

* Whether evaluating the comptime portion of a Zig program will take forever,

* Whether the compiler fails to exclude a particular function from being used as a function pointer at a particular place.

Turing-completeness is a wildly powerful property, but that power is not free; the inability to figure out what might happen in a program is only just the biggest and most apparent cost.

The problems this might cause can be summarized like this: you can never know what a program will do for a given set of inputs until you run the program on those inputs, and even then, you might never know if the program never halts.

Does that make sense?
As a user of AWS/GCP/Azure, Azure is the one where we have the most issues, the most services that somewhat work but never right and where it is the biggest pain to actually get up and running successfully. We've also run into a lot of random limitations that are massive pain points in building automation against Azure where there's a mixture now of terraform, Powershell, and Azure Resource Manager templates to try and enforce state.

We have also found that we are spending almost 25% more in Azure for similar compute capabilities as we've had to launch more servers to meet expected baseline performance (or pricier systems).

The lack of proper AZ's in certain locations is also a huge bummer, on top of that, we've found that in certain regions you will have certain instance types that are available in one AZ but not the other. So you end up having to find somewhat equivalents and rewrite infrastructure as code to deal with that mess.

Last but not least is the fact that GCP and Azure both don't have great support for IPv6. AWS may have been late to the game, but it's easy to deploy, and it just works. Whereas in GCP you have to be in certain regions, and in Azure I still am not sure what they were smoking with giving such a tiny public IPv6 prefix: https://learn.microsoft.com/en-us/azure/virtual-network/ip-s...
As mentioned by gregjor business pay people to solve business problems but given your interest in pure tech I would look for companies who's core business is something purely technical (example: DevTool companies are a great place to start).

Unsure what you mean by "senior" roles, but in most large companies it's what you described as not wanting to do: tech + non tech responsibilities. If by seniority you mean owning a larger piece of the codebase and solving challenging problems I would look more for roles of "founding engineers" or simply "software engineer" at early stage startups (again building software that has a technical edge).

The smaller the organisation and the more its business is purely a tech product in itself the more likely it will align with what you're looking for (+ you'll be surrounded with like minded engineers). Hope it helps :)
Yes! I'm Johnny.Decimal and I'm starting to advocate for the idea of 'the Librarian' at work. You need someone to organise your stuff. That person needs the right skills -- passion, even -- to do that job.

Today that role is filled by either a) nobody or b) the lowest lackey who doesn't give a hoot about the concept.
When you put it like that it sounds really difficult, but what exactly would it mean to "completely rebuild"?

IMO it could look something like this:

- Governments around the world set up a Climate Change Council

- The council is given power to regulate industry, and assign national resources

- High impact industry is shut down or refactored. For example, coal should be banned, but oil companies should be nationalized and fazed out while alternatives are built

That's pretty much it. It's hard, and it's a large effort over a long period of time, but there's nothing impossible about it. We don't have to reimagine society to do it.

Personally the appeal isn't high for me myself, but I tend towards more DIY. And I generally feel like a little nit doing an ec2 copy is a poor indicator, and that platforms tend more towards being at parity than differentiating.

My tiny little Azure Cloud nit on a rare-for-me encounters with Azure Cloud was the dev tools requiring two totally separate login types for seemingly no real reason other than a lack of updating a legacy system, and that made me forever think Azure Cloud was kind of dialing it in. It made working with them more complex than anything else I'd worked with.

One thing I think we agree a lot on is the value of good directory services:

> Today, when I go and look at Azure Active Directory, I have a level of confidence that simply does not exist anywhere else. Everything can be made to suffer our policies and procedures from top-down.

With my interest in DIY, self-hosting, I have long & increasingly felt like the weakest link is Directory Services. Tons of great great ways to run operate & maintain systems. But man, keeping track of employees (and ideally users too, albeit in a separate Directory) is hard! Roles are hard!

Red Hat's FreeIPA is good stuff (albeit on the somewhat off base/lower development 389ds Directory Server), a huge collection of tools to help setup infra. But it's been fairly inaccessible until semi-recently & it definitely requires significant growing in & expertise. And it's one of the only high-integration options out there. There's tons of great tools that complement each other well to build amazing directory service systems, but FreeIPA is one of the only already well integrated options.

And it's still only semi Cloud integrated. Trying to setup Kubernetes to use this all is still a huge second feat. I think, with the native cloud world, the directory service concerns are rapidly becoming the biggest gate, the worst hurdle, for those trying to set themselves up as capable computer operators. We seemingly both share appreciation for this task.
Companies will not find unlimited liquidity at given share prices.
The problem, IMO, is the muddying of the managerial role, such that they now do 2 separate roles, one of which is overpaid, the other not. The computer all but killed the secretary, and the remaining (computer-assisted) secretarial duties got split between the ICs and management. Because you can only dump so much secretarial work onto your ICs before they stop being able to produce anything, the managerial level got a bulk of the secretarial work, which in turn prompted more hiring at the managerial level. On top of that, it represented a flip-flop in power dichotomy, because the managers still have their managerial duties/powers: the people doing a lot of the secretarial work now have the power to fire the people doing the product work. Combined with people's self-interest in protecting and building their own positions, this leads to secretarial work bloat, and thus even more managerial bloat, and an increase in secretarial workload on the ICs.

My pitch for a the ideal corporate structure: bring back the secretaries. Re-introduce the division between your secretarial work and your managerial work, and shrink the number of managers by a significant fraction. Ideally, the result is A) fewer managers means more budget for hiring better mangers B) less secretarial work among your ICs and managers boosting both productivity and job satisfaction C) flatter management hierarchy means less information loss between ICs and the top decision makers and D) the people doing secretarial work no longer have the power to shunt that work off onto the ICs.

> IKEA has always fallen apart when you try to move it

IKEA has different levels of quality, including amazing cardboard LACK.

IKEA also has a lot of solid wood furniture.

What pertains to the article, is that IKEA is keeping prices of the expensive stuff lower than competition... by pushing materials to their limits.

I had moderately expensive IKEA furniture and I had "designer furniture". IKEA isn't much different. I have Besta unit, that has moved multiple times thousands of miles over the last 8 years... still looks pretty good.

> Totally agree. Online shopping is only going to get worse: more expensive, less quality, harder to return. On the other hand, brick and mortar places are going to have less variety, and lower quality

What I am hoping might change things is a near-total collapse in the value of commercial & retail real estate. This is clearly already happening and doesn't show any signs of slowing - who is going to take a long term, expensive lease on retail real estate now?!

But once prices have collapsed & property owners are forced to adjust to the new reality, I'm hopeful it might lead to a bunch of new competitors able to roll the dice by focusing on smaller scale speciality stuff, which will eventually grow. Kinda like capitalism has promised forever, except maybe this time it might actually happen?!
I am currently reading the gorgeous Folio Society edition of the A Man on the Moon
The Voyages of the Apollo Astronauts by Andrew Chaikin (worth a buy from https://www.foliosociety.com/usa/a-man-on-the-moon.html if you a) like the topic and b) have 235.00).

I just finished the book 1 which ends with well known Apollo 13 disaster and the RCA of the explosion is that the liquid O2 tank for the fuel cell was intended for Apollo 10, but was removed for modifications, and during that was dropped about 5cm, a "minor jolt, but enough to damage the tube assembly used to fill and empty the tank". As part of testing - and under full, and capable supervision of NASA astronauts and mission control - the tank was filled and tested, and would refuse to drain fully due to the tube assembly being in the way. Alternative procedure to empty it was to heat it with the internal heater and have the liquid O2 simply evaporate. BUT! The heater inside was originally spec'ed to use 28V, but was upgraded to 65V, and everything in it was redesigned to do so, EXCEPT the thermostat inside the tank itself. The thermostat was supposed to provide temperature control and shut the heating process off if temperatures exceed things. Well, during that ground draining operation the 65V fried the thermostat, and the temp gauge on the ground only went up to 85 degrees. The insides of the tank went up to a 1000, which cracked the insulation on the wires of the motor designed to stir the tank, and those arced while in transit to moon and boom, made that mission what it was.

So yeah, space is hard. I am sure the mission people for the lander will do their design review and I look forward to their findings.
The COVID effect was mostly one of trend accelerations: more people using online services for everything, delivery for everything. It produced a shock that is currently changing our infrastructure patterns.

We learned relatively quickly that although the streets cleared out, our energy use stayed roughly similar overall, and the supply shocks are tied to that story by shifting demand for goods and services in a relatively short period.

Back-to-office is also part of that because one of the goods and services that could not move that quickly is real estate: individuals could move, but businesses had leases. And everyone looking at the commercial real estate market has been shaking their heads and seeing a negative trend: yes, companies did mobilize to get people back on their office commute, but the market is still sliding and cities are looking at the difficult prospect of converting commercial buildings to housing now.

I'm 30 and this is my situation:

- I have health issues that decrease my quality of life and leads to embarrassment. I can't work an in-person job anymore.

- I work freelance but have one client, and they're an miser - very tight with cash, so I barely meet my minimum needed income to cover expenses and save a little.

- Because of the above, I have been stuck in a very poor apartment for the last 8 months. Water leaks, air quality issues, noise, shit-water rings around the toilet base, dangerous electrical faults, etc

- Prior I was a late to graduate college student, then worked at a few corporate jobs, but it killed me to be a part of that corporate dysfunction I saw every day.

- I quit multiple jobs because they burned me out.

- I think I'm still burned out because my client is being a prick, not giving me the hours I need yet expects me to be available.

- I keep thinking about starting my own business, but no sustainable income = no business

- I have an addiction to THC edibles because it makes my situation feel less hopeless.

- I'm a complete idiot see above.
That's not how this works. Plate tectonics won't stop if you cool down things a little bit. The amount of cooling you'd need to do amount to have that stuff stop is comparable to creating forests and oceans on mars. Not gonna happen, we'll kill off humankind before that.

Amazon only has AWS, their retail business isn't worth that much (maybe $200 bil max, given low margins). Online2Offline has mostly a disappointment, as the margins of tech just could not be replicated in offline businesses.

Microsoft has O365 (Dominant business tool), Github/Vscode (Dominant coding tools, also perfect datasource for AI coding), Gaming (Windows is still overwhelmingly dominant in gaming, and also Xbox exists), AI (They own 50% of OpenAI), and finally Azure.

Alphabet has the consumer google suite (Youtube/gmail/google) that just prints out extremely high margin cash. They also have android/chrome as defensive moats for the core suite.

Hence Amazon only beats out Meta in stock valuation

I'd think we'd have already seen this with GitHub Copilot. There was an interview I was part of late last year where the candidate had Copilot turned on during the live coding, and he didn't turn it off even after it was obvious that's what he was using. What I was more surprised by is how I thought this was a bigger deal than everyone else. Like, why come up with these elaborate tests when the candidate is just going to use autocomplete the whole time?

Maybe programming in another few years will just be glorified autocomplete and little more.

And perhaps testing people on how to write code was a mistake to begin with. It's one thing to write code, but reading code is another.

A Platform for Sharing Interview Recordings
I'm exploring an idea for a platform that will allow job interviewees (esp. techies) to share their interview recordings to help others prepare for similar interviews. I believe this will be extremely valuable for job seekers who are looking to improve their interview skills and gain insights into what employers are really looking for.

However, I'm aware that privacy and anonymity is a big concern and I want to make sure that interviewees feel safe and comfortable sharing their recordings. So, I've put a lot of thought into how we can ensure anonymity while still providing valuable insights to job seekers.

Here's what I'm thinking so far:

- All videos will be completely anonymized before being shared on the platform. This includes blurring out faces, changing voices (if requested), and removing any identifying information such as company names and any personal info.

- All videos will be thoroughly reviewed before being published to ensure that they meet strict standards for anonymity and content.

As a means to reward them, interviewees can also choose to receive compensation for their video through a system similar to Buy Me A Coffee where viewers tip them if they found it helpful.

I would really appreciate any feedback on this. Do you think this would be valuable for job seekers? And do you have any concerns or suggestions?

Let me know what y'all think!

These high density batteries are going to allow you to have the same range with fewer batteries. Most Americans will find an upper bound of 500 miles to be pretty reasonable for a car. Most American's don't drive 500 miles per day and thus won't be charging a full battery pack every day.

You should consider upgrading your car solely for the fact that newer cars are significantly safer in crashes.
I bet this wasn't motivated by the sys admin use case; as you say, people like you don't need this because they will do it manually with shell commands after due diligence.

This is for development environment: you know that tool foo always runs on port 8888; you want a clean slate before rerunning your tests/dev server/ whatever.

(But sure, personally I would say people should learn enough shell programming to use shell commands for this, or even make their own utility as a shell script/function, rather than use a one-off tool).

Versioning does not solve the problem.

The aligned allocation operators have existed since llvm 8.x.

The problem is not that the aligned allocation APIs are new. The problem is that TCMalloc is only partially replacing the global allocation APIs, it's just taken until this year for that bug to be exposed.

What has happened is presumably some part of the OS has updated its target C++ version so is now using the aligned allocators, which exposes the gap in TCMalloc.

I'm not sure if the spec explicitly allows an aligned allocation to be fed into an unaligned operator delete, but it seems like implementations do, so that's probably why adopting aligned operator new wouldn't be seen as an ABI break.
No, if you live in an apartment your typical experience right now is one of rent increases pricing you out of your neighborhood - if you owned a home this wouldnt be a problem. So living in an apartment kinda has an implicit expiration - your time is up once you get priced out.
