grumpy_coder··on A practical guide to AI image generation, from diffusion to agents
All of that still reads as a non-professional messing about at ten different things.

If we want to use a pixel art generator commercially we need 'practical guide' to making a small change to one animation, two months after creating the original character.

We need images generated in psd layers, with actual text using a font.

Sticking to the brand palette religiously.

grumpy_coder··on There is more to code review than (automatable) detection
Code review was pretty rare until Github launched in 2008 and made it very easy to add to your process.

I honestly didn't see as much improvement in code quality as people assume. Friends approve their friends PRs. Most coding cultures really push back on refusing a PR.

Automated testing in CI was the much bigger improvement, at least the code compiles now.

grumpy_coder··on Don't couple your Go code to GitHub
How many other people have hit the pain of injecting ssh keys for gitlab into a docker container building your code in CI?

Compiling code shouldn't hit network by default.

grumpy_coder··on The American Religion of Self-Storage Facilities
Cities have started to fix it, but it was mostly a zoning loophole. Protected industrial zoning typically allowed building 'mini warehouses' with limited public comment, no parking, on land that was fairly cheap.

Made self storage plentiful and cheap in areas where housing lot sqft was limited.

grumpy_coder··on The labor share of income in the US is at its lowest post-war level
You have to have access to far more than $250k to be willing to blow that creating a startup. I may give my kids $250k for a house to live in. I do not have enough for them to yolo it on a dot com startup.
grumpy_coder··on The room the economy can't see
Unfortunately were I live...

The sports clubs were bought out by private equity and charge large fees. The local park is rented to the same private sports teams 7 days a week. The local elementary closed it's playground. (been open for 40 years, installed gates 5 years ago) Only scouts at the church remains, and it has become oddly focussed on getting fairly rich kids into college.

grumpy_coder··on Oracle files H-1B visa petitions amid mass layoffs
The cuts include workers in senior director and vice president roles, as well as managers, product developers, product managers, program managers, software developers, site reliability developers, technical analysts, user experience developers and others.

They are in no-way laying off call center employees, they are laying off tens of thousands of the most highly paid US workers.

And yes the numbers of H1Bs granted in 2025 is relevant. You don't layoff 20% of your 100,000+ people workforce all of a sudden 'cos March went badly.

grumpy_coder··on High school student discovers 1.5M potential new astronomical objects
The schools studied in that paper are free, or close to free. Not $50,000 per anum And I don't think OP was suggesting it's the quality of education that affects outcomes in attendees of expensive private high schools.
grumpy_coder··on Architecting large software projects [video]
Yeah, I think the first mistake is thinking 'large software project' is specific enough to have any good advice at all.

Large software projects could include AAA console videogame, or banking mobile app, or embedded vehicle entertainment system, or airport baggage handling system, or hundreds of other totally different domains.

The only good advice I can think of is given a large software project try to hire someone (or a whole team) that have built something pretty similar before.

grumpy_coder··on AMD CEO sees chips from TSMC's US plant costing 5%-20% more
A fine time to cancel Larabee properly and get serious about specialized GPU hardware five years earlier.
grumpy_coder··on The Death of the Middle-Class Musician
The grocery bagger on a zero hour contract needs to be able to survive when not given 40 hours. Also the 5% unemployed people in a 'full employment' economy need to be able to survive when sacrificed to control inflation.
grumpy_coder··on The Death of the Middle-Class Musician
Have you seen how much money we are shoveling into 'AI'
grumpy_coder··on The Who Cares Era
Boeing has consistently underperformed the market massively since the MD merger. Making maybe 3% after inflation
grumpy_coder··on The Ingredients of a Productive Monorepo
Monorepo very often means bazel for tooling (rbe and caching tests) and that means one WORKSPACE with common versions of libs.

Monorepo also means a team 'vetting' new thirdparty libs, and a team telling you your CI takes too long, and a team telling you to upgrade your lib within 23 minutes because theres a security issue in the korean language support...

grumpy_coder··on Career Development: What It Means to Be a Manager, Director, or VP (2015)
in this context 'your boss' is usually a level or two above your direct manager on org chart Take it as the most senior person you can get regular face time with, this also needs to be gamed.
grumpy_coder··on uBlock Origin is no longer available on the Chrome Store
More like the willfully blind engineers, disingenuously claim to believe that absurd bullshit. There's not a lot genuine left in that company.
grumpy_coder··on Should managers still code?
Should managers exist?

We got along better before all these managers arrived, could ship huge projects with 100 people and one ceo. And the ceo wrote code and didn't do any of the nonsense most managers fill their days with.

grumpy_coder··on How the U.K. broke its own economy
Then when you need to buy a house you have to leave.

Net migration to London from the rest of England and Wales is only positive for those aged 20 to 27

There's plenty of great experienced people outside London, but all the rich (business owners) are openly prejudice to everywhere else. https://www.bbc.com/news/videos/cwy57v07gn2o

grumpy_coder··on It’s still worth blogging in the age of AI
Me too. At least i can be wrong in private that way.
grumpy_coder··on Do you want to be doing this when you're 50? (2012)
This sounds far more real to me than the original post. All the technical issues in the world don't bother me unduly, it really is the managers who make you hate work.

Money wise these corps are a system of their own, they pay enough to make you not quit. The more they pay, generally the more they suck.

Just need to wait till my 401k doubles one more time, my kids finish college, and the house is paid off.... just 10 more years

grumpy_coder··on Don't "optimize" conditional moves in shaders with mix()+step()
I believe the conclusion is correct in 2025, but the article in a way just perpetuates the 'misinformation', making it seem like finding if your code will compile to a dynamic branch or not is easier than it is.

The unfortunate truth with shaders is that they are compiled by the users machine at the point of use. So compiling it on just your machine isn't nearly good enough. NVIDIA pricing means large numbers of customers are running 10 year old hardware. Depending on target market you might even want the code to run on 10 year old integrated graphics.

Does 10 year old integrated graphics across the range of drivers people actually have running prefer conditional moves over more arithmetic ops.. probably, but I would want to keep both versions around and test on real user hardware if this shader was used a lot.

grumpy_coder··on Ask HN: Promoted, but Career Path Derailed
"it will almost certainly double in value in 7 years" implies 10% is an almost certain long term return. It is not.

10 years is a common rule of thumb to double your investment, this is a good guess since after adjusting for inflation, the real return of S&P 500 is about 6.8%. Which is about 10.5 years to double your investment.

(give or take S&P 500 being one of the best returns you will find historically)

grumpy_coder··on Mistakes engineers make in large established codebases
I see an over-reliance on automated tests recently. Often suggesting just passing the CI tests is enough to approve a change. In ancient code it's just as important to limit the blast radius of your changes, and have a good reason for making them. Not changing something is the ultimate way to prevent a regression.
grumpy_coder··on Insurers rely on doctors whose judgments have been criticized by courts
It's also important to realize claim denial isn't the same for all customers. When I was classed as an executive at a large blue chip company, my claims were approved quickly and easily at the company specific hotline. With the same provider, making the same claims, they are now partially denied initially and it requires long phone calls to get them to admit they should be covered and often it just isn't worth the hassle.
grumpy_coder··on US weighs Google break-up in landmark antitrust case
That game already exists. Intel and Amd had an odd relationship for years when Intel needed Amd so they could claim that competition existed. Cross licensing instruction sets and the like.
grumpy_coder··on Foundations: Why Britain Has Stagnated
They are referring to the liz truss budget.
grumpy_coder··on Companies need junior devs
100% this; unfortunately also often seeing junior devs called staff after job hopping for 3 or 4 years never really learning anything.

Junior job titles are nearly as much of a mess as interviewing them.

Particularly in recent hot topics like AI the reality is you want both experienced and less-experienced devs. Most AI teams I see actually lack AI experience and keep falling for the same issues (like quickly getting to 80% working and thinking just a bit more data to 99.9%)

grumpy_coder··on Tesla’s TTPoE at Hot Chips 2024: Replacing TCP for Low Latency Applications
"Instead of using typical supercomputer networking solutions like Infiniband, Tesla chose to adapt Ethernet to their needs with a modified transport layer."

So, they need to compare it to Infiniband, not TCP, and definitely not software TCP. And they need to explain how/if it works with standard huge capacity switches (which is at least a reason to prefer TCP over Infiniband).

There could be reasons to build this, AWS have something, but for Tesla to build their own stinks of NIH bad.

grumpy_coder··on Problem with selling developer tools is that devs have no purchasing authority
Generally, nobody has authority. Even the highest executive has to fight procurement in a big corp. Own a VC-backed startup, the investors want you to get prior agreement on 'large' purchases. Maybe if you are the sole owner of a small firm without a purchasing department.

Politics always has people insert themselves in the flow of money.
