I should also point out that this is a common misconception for hardware/solution companies. Very hard to make enough money to fund R&D with consulting. I did that for the first 4 years of the company. Put bluntly, that model, th

I did that at the beginning. Until I had enough cash to build and market product. But it was barely enough cash. Then big orders started hitting. Before I knew it, we were at $3MM/y sales, growing about 33% yoy. And then we crashed.

There is a saying in karate. Fall down 7 times. Get up 8. But also, definitely, make sure you are not going to be financially destroyed by your actions. Take time to be with your family. Remain focused upon your life, and life goals. Do

Here here. When you empty your 401k to build your business, and don't contribute to it for 15 years while you are building, as you simply don't have the cash, and cannot afford it ... Yeah. The implicit assumptions of the "

As one who bootstrapped, took that risk, and lost ... everything ... I've been talking passively about this for a while. I speak with startups who have a product that is poorly differentiated, me-too like, that think they are going to

Not entirely true (that we understand magnetism). We get some things about it. But not everything. The nature of physics is such that we never really have 100% confidence in our theories. We are always looking for things the theory under

I wanted them to open an academy. Even though I am likely too old for it, I'd definitely apply to be a space cadet.

Simple. Friendship transcends posturing and virtue signalling, at least for me. Dropping someone as a friend because we disagree, at a deep and fundamental level over something important, doesn't preclude us from having other common

Why do you assume that I am not a minority or that I have not experienced such discrimination? I am a religious minority and have experienced this my entire life. Overt in school and grad school. Less overt but still there in professional

That there was 'punishment' for expressing an opinion that is not aligned with a particular world view, by donating money to support something that was in the majority world view less than a decade before ... should be terrifying.

I've worked at a company where every single meeting I had with a certain set of engineers started and rapidly devolved into a political narrative of how bad certain groups where. I smiled and ignored them. I subconsciously made sure t

I wish I could upvote this more than once. Metastasized is the appropriate word.

This article calls out the dangers of corporate virtue signalling. I have many friends and acquaintances that do the personal version of this, and are part of the problem. Honestly, I think the only way to combat this is to make taking the

Yeah, the article was weak. I must have missed the compelling reason to switch off of a live language to the EOLed one. And ... did they actually, really do that, for a critical piece of infrastructure, because someone dislikes perl? That

Seems to be common amongst pythonistas. I've run into their tired bashing of perl for 20+ years. I use perl daily. And Julia. And C. Python more like weekly. Always select the right tool for the job. Changing code that works, and

> There are no photons in free space. Um ... I'd suggest rewording that, as this wording is incorrect. Cosmic background photons would likely want to have a word with you on this as well. It is true that what a photon is in a physi

Any data to back up this claim? My experience in dealing with large numbers of files, huge data sets, is that Perl generally roars, while python lags. I converted a python code to Perl associated with some recent work, and got a good ~2.5

No, the numbers are pretty accurate. In most of the cases I've run into, Perl is faster than Python for its operations. Some trivial examples[1] showed up on HN a few weeks ago, about how this person "optimized" python, by

In my 30 years (yes) working with Perl (4->5.32), I have never, once, used wantarray. Perl does not lend itself to bad code. Bad coders, people whom cannot use or articulate good practice in coding or documentation, lend themselves to

Hmm ... don't conflate the presentation UI with the underlying language. I wrote my companies website (2 jobs ago) in Mojolicious (perl web framework), with a responsive UI, based in part upon bootstrap. Very modern (for the time) UI

Lots of new things. Perl is an immensely powerful language. If you know how to write code well, it will be fully comprehensible by even casual programmers. Many orgs ship perl based tools as current, up-to-date products. Mellanox OFED is

On my multiple Linux laptops, suspend just works. Has for a long time (many years) with no tinkering. In this case, MBP is uncommon HW for Linux users, and things may not work that well. I imagine windows 10 would have similar problems th

Alternative theory. Perl aficionados have a long history of being on the receiving end of passive aggressive language zealots. Usually they are Pythonistas, but others have joined in as well. You see this in messages that say "perl is

I kept that in simply to keep the "playing field level", as I run Julia code as "scripts", knowing full well that it is far more powerful than that. I do use BenchmarkTools.jl as well, though I've found TimerOutputs

Honestly, this is subjective. I generally agree that some languages are well designed for fast prototyping, but not really great for computationally intensive production. I see Python in this role. Note that when the original author wishe

I know this is supposed to be about python optimization. However, the post switches over to C at nearly the beginning of the process. Hence it really is about how to optimize python applications, by rewriting them in C (or other fast lang

I rewrote the benchmark in perl and julia as well. Kept it to its origins, and including startup interpreter time. Original python: #!/usr/bin/env python3 def main(): for j in range(20): for i in range(1000
