And induction gets hot immediately. And it is easier to clean. And it is less likely to cause fires. It's just a better technology all around when compared to gas stoves. The only issue I personally have with it is that it is not c

I agree that visualization does not need to be perfect. One issue is that "correct visual output" depends on your expertise level. A visualization that is good to teach undergrads may be frustratingly bad to experts and research

I get what you are saying, but my issue is not that it runs a script. My issue is that curl piped into a shell does not verify that the download is from the original source before running the script. A .deb file has many advantages over cu

You raise a good point. This is why people sign the checksums. The signature confirms that authenticity of the checksums. That somewhat moves the goalpost, though, since it then depends on where you got the source's public key, but

Curl does verify certificates [1]. That does confirm that your connection is to the right server, but it does not confirm that the files were unmodified. SSL/TLS/HTTPS is more about encrypting the traffic and ensuring that there

The issue does not have to do with whether the download is a binary or source code. It has to deal with verifying the integrity of the download before installation. Curl piped into a shell command provides no means to verify that the downl

I still have no comprehension of how curl piped into a shell command has become the default installation method for many projects (looking at you, Rust...). It breaks my brain as to how potentially unsafe it is.

Von Braun was not "just lucky" to get captured by the US. He and his immediate staff took active steps to get captured by the Americans [1]. [1] https://en.wikipedia.org/wiki/Wernher_von_Braun#Surrender_to...

I imagine that it could be usage, but it also could be fewer people caring to report issues on the weekends too for that matter.

The issue, in my experience, is that there is a lot of productive work that does not look productive at first glance. Long term work may not look productive for years until it suddenly is tremendously productive. And there is a lot of qui

I've often described this as a bias towards easily taught ("teachable") material over more realistic but difficult to teach material. Sometimes teachers teach certain subjects because they fit the classroom well as a medium.

Even if this line is true, and I am not saying that it is, running and other cardiovascular activities lower your resting heart rate [1]. So even if you believe that you only have a finite number of heart beats, running should in fact incr

I completely agree. The issue is that some misconceptions just never go away. People were talking about how bad lines of code is as a metric in the 1980s [1]. Its persistence as a measure of productivity only shows to me that people feel

I spent around 170 hours on this so far, with only 60% of that being coding. The rest was mostly research or writing.

Before I started the project, I was already vaguely familiar with the notion of an inverted index [1]. That small bit of knowledge meant that I knew where to start looking for more information and saved me a ton of time. Inverted indices

I recently wrote a command-line full-text search engine [1]. I needed to implement an inverted index. I choose what seems like the "dumb" solution at first glance: a trie (prefix tree). There are "smarter" solutions li

Reading that particular section made me think of the tree swing cartoon [1]. I agree that the best engineers have likely been on the ground making concrete changes at some point, watching bricks being laid as you said, but I have encounter

The language enforced difference is that only functions can return a value, but other than that, they are quite similar and just called "procedures" generally. In my experience, Fortran programmers use them differently in practic

by atrettel 10mo ago
They are pretty similar, but they are definitely used differently. For one, you have to "call" a subroutine in one statement, but you can use multiple functions on the same statement (since they can return values). Functions (us

Yes, sorry for the confusion. To be clear, the quote is directly about spaces not being significant in the source code in general, but I was commenting more about how this mindset affects variable names in practice. At least in my experie

by atrettel 10mo ago
The article did not discuss this, but to me, one of the bigger differences between Fortran and more modern languages is the difference between functions and subroutines. Yes, they are not synonyms in Fortran and serve different purposes.

There is actually a lot of debate as to whether scientific discovery is driven by "heroes and geniuses" (as you argue) or by multiple people simultaneously and independently coming up with the same idea [1], often called "mul

It's not just for universities and for CFD. Slurm is the primary job scheduler at Los Alamos National Lab. I know other federal labs that use it too. It is just really popular in general.

I agree with the notion that LLMs may just end up repeating coding mistakes of the past because they are statistically likely mistakes. I'm reminded of an old quote by Dijkstra about Fortran [1]: "In the good old days physicists r

I really like that Vanguard supports Yubikeys too. They are the only ones that support them in my experience, but I have seen some increased support for TOTP in financial institutions lately. Fidelity now allows for TOTP instead of SMS.
