commonlisp94··on West Virginia University to drop 32 majors including all world language programs
What would you do to collect this information? Keep in mind most of your administrative workers will be uncomfortable learning or doing anything new.
commonlisp94··on West Virginia University to drop 32 majors including all world language programs
This is essentially written by bitter ex or current employees.

Professors often approach public debate by assuming everyone else is braindead, rather than puzzling through conflicting information.

For example, they immediately dismiss the president's claim that a demographic change contributes to this issue as "false" because the US birth rate may have been very stable. But that says nothing about parents in the WVU area, which we know are either older or moved to other states.

> I'm lucky that I've had a long career and my skills are very much in demand, so I will always be able to find a remote job somewhere.

Yep, this is exactly who WFH benefits, and nobody else.

I disagree. The vast majority of people benefit from basic supervision and accountability.

Yep, what you want is a good and predictable approximation.

> What point are you trying to make?

In practice most Matlab solutions you are describing are awful, in terms of performance and in terms of accuracy due to ignorance about underlying theory.

commonlisp94··on Students’ insight proves that the local-global conjecture doesn’t hold
It's really not. No problem looks exactly like the textbook you have to use analytical knowledge to devise a solution.

> The point is that 3-5 years of analysis might be an overkill

Rarely have I met an engineer and said, wow that guy knows TOO much about math. What do you think they should substitute?

Partition point is even simpler and can be optimized the same way.

> if you don't need the more general case and its associated performance cost

In C++ the "more general case" typically doesn't have a performance cost.

commonlisp94··on Students’ insight proves that the local-global conjecture doesn’t hold
The math literacy here is pretty poor when people imagine mathematicians to be solving college "calculus and algebra" problems.

> Having matlab at hand makes it possible to save years of analytical tinkering and simplifications and approximations.

And they use poor and imprecise approximations that they can't debug, because they just plug in numbers and hope for answer.

> I will never need it as numeric methods took over completely

What if you want to make a numerical method for something you can't look up the recipe for?

lower_bound and upper_bound are typically implemented in terms of partition_point, which is much more general than this version of lower_bound taking an element.

Good point. I don't think anyone actually uses it for containers that only support forward iteration. But the author did declare the signature with ForwardIterator.
commonlisp94··on Paul Graham on Conversations with Tyler
You can share all the true examples you want. But 19th century France and 20th century America have completely different economic models. So we can't understand that purely by studying French literature.

> “Behind every great fortune lies a great crime."

This quote reflects a very European attitude towards wealth to me. I believe PG specifically talks about possible origins of this idea.

commonlisp94··on Want employees to return to the office? Then give each one an office
They have plenty of choices, including:

- visa workers who have no bargaining power.

- younger people who are mobile

- moving offices to other places

There have been a few recent posts about struggling to find jobs... every time it turns out they are only applying to online listings for remote jobs, and have high standards. That's not a situation you're likely to stand out in.

I just don't see how global remote work as the norm is "pro worker" for anyone except those already well established in their career. Besides being more disposable, what happened to complaints about companies not providing job resources or training? Did we give up on that one?

> You can't be serious.

Ok, im serious. It's silly to quote someone when you don't have a rebuttal.

2008 was 15 years ago, and didn't hit tech as hard as other industries. The last serious one was early 2000s. A significant number of people "in it for the money" or with non-traditional credentials simply had to leave the field.

There is a detailed PDF manual that explains every feature concisely, you just can't google for the answers.
commonlisp94··on Google Maps has become an eyesore
I don't think the issue is digital maps, just that the data is not accessible or preserved.
commonlisp94··on Edsger Dijkstra’s One-Day Workweek
one related thought: many of the ideas he is famous for (and are named after him) came from his memos. Can you imagine an academic even acknowledging they got an idea from a non-peer reviewed sources, let alone giving him the credit?
commonlisp94··on My frugal indie dev startup stack (2022)
People used to make websites by uploading some php or perl scripts to a shared server (or just buying a domain and pointing it at their home ip). In that context, I can't imagine someone writing an article like this.

> if I was a Turing prize winner like he was

That came later. He just had a flexible gig that was common for researchers at the time. From what I can tell, none of his behavior would be accepted today:

- participating in a new field without formal credentials

- not writing papers or participating in peer review

- writing books and papers without citing other works

- bouncing between academic and industry roles

Academic research is just a different world, with very different life tradeoffs, even for "big' names.

> I think there's a lot of nostalgia at play here

I don't think that's the case with latency, as we can measure that directly.

> There's a lot of ways in which modern computing is far nicer than it was in the past.

And resource consumption and latency isn't one of them.

commonlisp94··on Google Maps has become an eyesore
I think this a myth told by marketing.

They already know the photos have the objects they are interested in. Are they still working on motorcycles buses and signs?

The recaptcha part doesn't even depend on recognition, it's just a statistical comparison with what other humans clicked on given the same prompt + some pointer analysis and browser fingerprinting.

commonlisp94··on Google Maps has become an eyesore
Unlike a physical map, we can't go back and access old google maps, so those changing preferences in style leave a memory hole.
commonlisp94··on Ask HN: What is the most powerful, fully open, fully programmable computer?
You don't need to write a software stack for that, just install something like netbsd.

I'm sympathetic to your argument, but I think also many problems (or popular implementations) turned out to be quadratic. For example, the resolution of windows 95 applications vs today.

Contrast helps. But running a convolution model on a single video frame, or aggregate of frames, is not how human vision works either. Give a human a glob of pixels with no context and they will struggle to identify it too. Identification involves motion and knowledge of the scene.
