That's also one of the more notable incompatibilities of zsh - by default it treats $a the same as "$a", and you're supposed to use arrays if you want multiple words. Although I'm not an expert - maybe ysh and zsh d

Ok, thanks. I was wondering because last year I spent a few hours poring through Redis documentation, trying to figure out how to get access to read-only snapshots...

by unnah 2y ago
But those Redis snapshots are only used for regular back-ups, so completely unlike snapshot isolation in a relational database, right?

So far I have avoided Powershell in anything distributed to end users, because execution of unsigned scripts is disabled by default in Windows. It has been easier to use VBScript or BAT files to automate basic tasks, since those scripts can

If you did partition all core resources between SMT threads, it seems like the end result would be exactly what was called "rentable units" above, i.e. you could convert a high-performance core into two lower-performance cores. Th

Yet another possibility is that there actually are papers laying out foundations of potential new fields in impenetrable prose... and then no one understands those papers and they are promptly forgotten. One can only hope that someone else

Maybe some designer/typographer nerd should make syntax highlighting rules that only subtly emphasize different syntax categories. I am thinking something with italics, slightly different font weights, and very limited use of colours.

Yes, there are definitely challenges, and there must be a reason no one is seriously selling 1024-core versions of old 8-bit processors... but perhaps on an Intel 130 nm process you could make a faster Z80 than just 50 MHz. Quick googling d

On that kind of process, you could make a 1024-core Z80 machine, leaving half the area for memory, interconnect and I/O. With suitably smart programming and an embarrassingly parallel problem, it might even be able to beat a Pentium II

It looks like standard C99 variable-length array (VLA) syntax: https://en.cppreference.com/w/c/language/array#Variable-leng... The major difference is when the array is multi-dimensional. If you don't ha

That would be a great use for an HDR screen - make the "indicator light" extra bright compared to the rest of the screen, to make it really obvious that the light is now "on". Of course this would only work as long as th

If you are open in your visa application about what you're going to be doing, then it's obviously all above the board. However, somehow I got the impression that many digital nomads would rather not to mention their work to any of

Visa rules were typically set up at a time when there was no such thing as remote work to speak of. When they mention working, they don't make any distinction between remote or local work. For example, a US B-2 visitor visa allows &quo

Ok, thanks - not sure how I missed that. I guess the conclusion is that we now have two pretty much complete reimplementations of ggplot2 available in Python.

by unnah 3y ago
Interesting. It seems the major difference with plotnine is that lets-plot is implemented in Kotlin and the Python package uses a Python-Kotlin bridge. Both lets-plot and plotnine are available under the MIT license. It looks like lets-plot

As someone who makes plots every now and then with breaks of several months in between, I have found the ggplot syntax surprisingly intuitive and easy to remember even after a long break. Importantly, the basic syntax can be used to compose

I don't think they're talking about a bound for the optimum objective value, but a theoretical upper bound for a covering radius related to a convex body and a lattice. The bound would be useful in a lattice-based algorithm for in

There are flat chess pieces that have the traditional 2D symbols on top. Another question is whether anyone makes 3D knight pieces that are designed to lay flat on the board. Such pieces would fit a "Godfather" themed chess set ra

I think Zilog still makes eZ80 based system-on-chip products, and eZ80 is backwards compatible with Z80. For example: https://www.digikey.com/en/products/detail/zilog/EZ80F92AZ02...

Yes, but C is a much more arcane and complicated language. Case in point: instead of writing a+b in Python, in C you would have to write a+b (Jokes aside, it would really be more complicated in C if a and b were actually strings or lists.)

A non-esoteric answer: in Forth dot prints the top of the stack and function calls are separated by spaces. Hence three dots separated by spaces is the simple and straightforward way to print the top three stack elements.
